Definitions
- the present invention relates to radio devices, particularly dual-position radio devices.
- Modern homes may have a plurality of various radio devices, such as mobile stations, wireless telephones, and as a newcomer, radio access point devices constituting a wireless Internet radio interface.
- Base stations and radio access point devices of wireless telephones are relatively permanently mountable in a given location. They are typically mountable in a vertical position on a wall or in a horizontal position on a desk.
- the base stations of wireless telephones often comprise a turnable and extractable telescopic antenna, which is turn- able to an upright position irrespective of the position of the base station.
- a telescopic antenna is also previously known to most users. However, a telescopic antenna is susceptible to bending and breaking, and soldered joints are often made manually during the assembly of the antenna.
- a telescopic antenna also comprises moving parts. A telescopic antenna extending from a base station may complicate the placement of the base station in an otherwise suitable location. In this case the consumer who acquired the wireless telephone easily leaves the antenna against the side of the base station, whereby the audibility naturally somewhat deteriorates.
- Wireless telephones often use frequencies below 50 MHz, whereby the audibility may remain reasonable irre- spective of the wrong position of the antenna.
- a radio signal below 50 MHz still 'bends' relatively well compared with for example radio access point devices operating at a frequency exceeding 2,000 MHz.
- An antenna provided on the circuit board of a device is considerably more in- expensive than a telescopic antenna and can be made fully automatically, i.e. it is suitable for mass production.
- An antenna provided on a circuit board is also covered inside a device.
- mounting the device on a wall or a desk causes the antenna to end up in various positions, whereby the radiation field generated by the antenna also turns in different directions.
- the disadvantage may prevent the use of directional antennas in devices mount- able on walls and desks.
- LPRF New low power radio frequency systems
- Bluetooth technology is an example of LPRF .
- Bluetooth is a widely known technology operating at a free frequency range in the domain of 2.45 GHz. This frequency band is usable worldwide and the range of systems operating at the band is typically 10 metres at normal power. Bluetooth can be applied to various types of devices to allow them to communicate with other devices.
- a micro-cell cellular, mainly indoor, network can be implemented for Bluetooth devices.
- Such a network comprises some Bluetooth base stations and a host server that controls the base stations. Since the network is intended for home and office use, it has to be economic and easily installable. Bluetooth base stations should preferably be freely placeable on desks, shelves or walls, for example.
- the above devices often comprise indicator lamps.
- the indicator lamps are typically LED lights (Light Emitting Diode), for which openings are provided in a cover of the base station and which protrude to some extent from their openings allowing the user to see the light emitted from the LED.
- LED lights Light Emitting Diode
- the procedure has drawbacks: a mechanical fastening for the LEDs has to be ar- ranged inside the device in the vicinity of the outer cover of the device, and electricity has to be conducted to them for their use.
- the most inexpensive way is to solder the LEDs onto a circuit board arranged close to the outer cover of the device. However, this is not always possible, particularly when aesthetic considerations are taken into account in the design of the cover of the device and technical restrictions are to be avoided.
- Aligning the LEDs to their openings may also require special carefulness in the assembly, and involves a risk of failure. If the LED is not aligned with the opening, it easily bends under the cover and in the worst case its legs may cause a short circuit. Openings provided for LEDs may also be perceived as a sign of old-fashioned technology.
- the finish of a device is indeed often improved by gluing a transparent plastic plate onto the openings, rendering the outer surface of the device uniform. This also facilitates cleaning of the device, since its surface does not comprise narrow sharp-edged recesses that easily attract dirt and dust.
- a recess must be provided in the cover for said transparent plastic plate, and the plastic plate has to be fastened to the recess (for example by gluing).
- a radio device comprising: a body defining a space inside thereof and at least one opening; and at least one light source for emitting light, placed in said space at the at least one opening provided in the body; characterized in that the radio device further comprises: a part to be fastened to the body; at least one photoconductor fitted to the part to be fastened to the body; and that the part to be fastened to the body is fitted to be attached to the body by means of the photoconductor so that the photoconductor settles at said at least one opening and at least partly outside said space.
- the same photoconductor is usable both for conducting light from the light source to the outside of the radio device and for fastening the part to be fastened to the body.
- the part to be fastened to the body is preferably a support device for supporting the radio device in the desired position.
- a radio device comprising: a body defining a space inside thereof and at least one opening; and at least one light source for emitting light, placed at the at least one opening provided in the body; characterized in that the radio device further comprises: a support device for supporting the body in the desired position, the body being fitted to be fastened to the support device at at least two different angles with respect to the support device; and at least one photoconductor fitted to the support device, the photoconductor being arranged to settle at the at least one opening defined by the body when the support device is fastened to the body, for conducting the light emitted by said at least one light source via the photoconductor to the outside of the radio device.
- said light source is an indicator lamp.
- said part to be fastened to the body is fitted to be fastened with a quick fastener. This allows rapid fastening without tools.
- the radio device of the invention is preferably installable on either a horizontal or a vertical surface.
- the same indicator lamp and photoconductor may be used to give signals to the user. Owing to the photoconductor, the indicator lamp need not be fitted to any narrow opening in the body, but the indicator lamp is placeable loosely and the light can be conducted into sight with the photoconductor.
- the radio device also comprises at least one circuit board in the space inside the body and that said at least one light source is installed on the circuit board.
- the antenna of the radio device of the invention can be manufactured directly on the circuit board, whereby it is inexpensive and suitable for mass production.
- the photoconductor comprises an end fitted placeable in said opening for fastening the body at a first angle to the support device and for receiving light to the photoconductor from the light source.
- Fitting the end of the photoconductor to said opening simultaneously fastens the body at the first angle to the support device and places the end in the vicinity of the light source allowing the photoconductor to receive light from the light source.
- the body also comprises a fastening part, the fastening part being fitted to attach to the photoconductor for fastening the body to the support device at a second angle, and the fastening part being fitted to direct the photoconductor at said opening for receiving light from the light source to the photoconductor via the opening.
- the fastening part both fastens the body to the support device at the second angle and guides the photoconductor to the opening for receiving light from the light source. This way light is received to the photoconductor from the same light source irrespective of at which of the first and second angles the body is fastened with respect to the support device.
- a support device allows the radio device to be preferably placed in the same position when placed on a horizontal and a vertical surface. This ensures that the antenna is in the correct position.
- the antenna is directional so that the maximum of its radiation pattern is substantially on the horizontal plane.
- Such an antenna is well suitable for use when the position of the antenna remains substantially the same irre- spective of the location of the radio device.
- Installing at least one light source directly onto a circuit board and making it visible through an opening in the body and a photoconductor according to the invention provides several advantages. Installing light sources on a circuit board is well suitable for mass production, since the light sources do not have to be separately fastened to the body and wires do not have to be drawn from there to coupling points on the circuit board. When a photoconductor is used, said at least one opening serves to let out light from the light source to the photoconductor, but the light source does not have to be flush with the open- ing. Accordingly, alignment of the light sources is not nearly as critical as if they were placed in confined openings in the cover of the body.
- a recess is provided in the body for the photoconductor so that the photoconductor settles substantially flush with the surface of the body at least when the radio device is placed on either a horizontal or a vertical surface.
- the side view of the photoconductor is conical such that at least one indicator light of the radio device slopes downwards in a wall installation and upwards in a desk installation.
- the support device is preferably made from a transparent material, such as plastic or glass, so that the photoconductor constitutes an integrated part of the support device.
- the body is fitted to be detachably attachable to the support device.
- the body is fitted to be fastened with a friction joint.
- the support device comprises a number of protruding photoconductors, and the body comprises corresponding cavities for fastening the support device to the body. This allows a home user, for example, to easily couple the support device to the body of the radio device at the desired angle for placement on a horizontal or vertical surface.
- the support device preferably comprises grooves fitted to a screw head for fastening the support device to a wall.
- a method for displaying light with a radio device comprising a body defining a space inside thereof and at least one opening, the method comprising the steps of: fastening to the body a part to be fastened to the body and comprising a photoconductor so that the photoconductor settles at said at least one opening and at least partly outside said space; emitting light in said space towards said at least one opening; conducting said light via at least one photoconductor to the outside of the radio device; and using the photoconductor for fastening to the body the part to be fastened to the body.
- a method for displaying light with a radio device comprising a body defining a space inside thereof and at least one opening, the method comprising the steps of: fastening the body to a desired position in a support device in which at least one photoconductor is fitted such that the photoconductor settles at the at least one opening defined by the body; supporting the body with the support device to the desired position; emitting light in said space; conducting said light via the photoconductor to the outside of the radio device.
- Figures 1 to 3 show a first configuration of an embodiment of the invention
- Figures 4 to 6 show a second configuration of an embodiment of the invention.
- Figure 1 shows a first configuration of an embodiment of the invention, wherein a base station unit 10 is being coupled to a base 20 in a first position.
- the base station unit 10 is a Bluetooth radio access point device operating at a frequency of about 2.45 GHz.
- the base station unit 10 is approximately in the shape of a tile, its dimensions (length x width x depth) being 10 x 8 x 5 cm.
- the base station unit 10 is fitted to be used in the upright position and the base 20 is fitted to support the base station unit to the right position both in wall and in desk installations.
- One lateral surface of the base station unit 10 is provided with a thinned part having an about 1-cm deep recess of the width of the entire unit.
- the recess is defined by the end of the base station unit and extends to about 3 cm from it.
- the surface of the thinned lateral surface, i.e. bottom 12 forms, at a distance from the end of the base station unit, an array of openings having five rectangular first openings 14 grouped at uniform intervals.
- the base 20 comprises a photoconductor part 22 and a background part 23.
- the base serves to support the base station unit 10 to its position of use (in this example upright) when the base station unit is being installed on a wall or desk according to the user's choice.
- a radio access point device should be installed once in a suitable place in a set of rooms, after which it is not necessarily moved at all, or moved only when refurnishing or when there is a need to change the coverage area of the radio access point device.
- the background part 23 is a plate intended to serve as a support surface for desk installation of the base station unit and as a wall mounting plate for wall installation.
- the photoconductor part 22 comprises five photoconductor bars 24 having a rectangular profile.
- the photoconductor bars are substantially parallel and in line with the level of the background part, at an about 4-cm distance from the level of the background part.
- the photoconductor bars 24 are of transparent plastic and they are fitted to settle narrowly in the first openings 14.
- the photoconductor bars comprise two ends: an end fitted to settle narrowly in the openings and a wedge part 26, which is fitted to penetrate the surface of the photoconductor part and whose structure and operation will be described later.
- Figure 2 is another view of the configuration of Figure 1.
- Figure 2 shows an end 28 of the photoconductor part and a body counter surface 11 , i.e. a wall beside the recess, against which wall the end 28 rests when the body is coupled to the base (see Figure 3).
- Figure 2 also shows the surfaces of the thinned lateral side of the base station unit.
- a cutting face 16 of the recess constitutes a second row of openings, comprising five rectangular second openings 18 grouped at uniform intervals, in the same way as the photoconductor bars 24.
- the second row of openings is intended for a second configuration shown in Figures 4 to 6.
- Figure 2 also shows that the photoconductor bars extend from the end 28 such a distance that, in the configuration of Figure 3, the photoconductor bars extend through the first openings 14, but do not extend too far inside the first openings so that the photoconductor bars 24 could harm the indicator lamps inside the body.
- the photoconductor bars are also fastened by friction to the body at the first openings 14.
- Figure 3 shows the configuration of Figure 1 with the base station unit 10 fastened to the base 20.
- the photoconductor bars 24 of the base are inserted in the first openings 14.
- the photoconductor bars lock the base station unit with respect to the base so that the base station unit stands better when arranged on the horizontal plane with the base 20.
- Figure 3 also shows that the wedge part 26 of the photoconductor bars 24 forms a light surface sloping downwards away from the base station unit. In this first configuration, the wedge part serves to conduct light via a photoconductor from the base station unit on a desk towards the eyes of a user standing in the vicinity or seated at a desk.
- Figure 4 shows a second configuration according to an embodiment of the invention.
- the base 20 is turned to the upright position such that the back- ground part 23 settles behind the base station unit 10.
- the photoconductor part 22 settles onto the recess of the base station unit.
- An end plate 29 that settles against the end 19 of the base station unit is arranged between the background part and the photoconductor part.
- Figure 5 shows a second configuration of Figure 4 with the base station unit 10 coupled to the base 20.
- the base station unit is preferably placed high up, e.g. at 2 metres, and fastened to the wall of a room. When placed high up, the base station unit has an unobstructed connection to the radio devices in its vicinity, since furniture and domestic appliances often remain below the straight line between the base station and the radio device using it.
- the indicator lights radiating straight ahead would be poorly visible, but the photoconductors 26 turn the indicator lights obliquely downward so that they are better visible to a user in the vicinity of the base station unit.
- the base 20 is intended to be fastened to the wall before the base station unit is fitted to the base. This al- lows easy and safe wall installation of the base station unit.
- Figure 6 is a cross-section of the base station unit 10 and the base 20 of Figure 5 at a photoconductor 24.
- the photoconductor bar 24 is inserted in a second opening 18.
- a circuit board 30 is arranged inside the base station unit 10.
- a directional laterally radiating surface antenna 34 is arranged on the circuit board.
- a light source 32 e.g. a LED lamp or a laser diode, is fastened to the circuit board in the vicinity of the first opening 14. Light from the light source 32 propagates through the first opening 14 beyond the wedge part 26 of the photoconductor bar, is immersed in the wedge part and deflected from the wedge part obliquely downwards as was described above in connection with Figure 5.
- the end of the photoconductor bar 24 settles in the immediate vicinity of the light source 32 and conducts light from the light source to the wedge part, from which the light is deflected obliquely upwards as was described above in connection with Figure 3.
- Figure 6 also shows that the second openings 18 serve as fastening parts for locking the photoconductors to the body.
- the body comprises tight guides, slots and other holders for the photoconductors for fastening the photoconductors to the body.
- the keys or the display of a radio device may also be illuminated in accordance with the invention.
- the invention is particularly useful in displaying indicator lights, since in that case several independent lights have to be displayed.
