Embodiments of the present invention relate to an apparatus. In particular, they relate to a novel network apparatus.
There is a convergence of technology in the field of mobile devices. It is not unusual for a single personal device to be capable of performing as a mobile cellular telephone, a personal digital assistant, an internet client, a network client, a gaming device, a media player (pictures, video, audio) and a media recorder (pictures, video, audio).
There has also been some convergence of technology in the field of home devices. For example, the functionality of a games console and a video player have been integrated.
There is a tendency, in field of home devices, to reuse existing hardware such as the processing power or the memory capacity of a home computer or a games console or the screen resolution of a large digital television.
However, reusing existing hardware perpetuates the patterns of behavior that have developed in association with that hardware.

According to various, but not necessarily all, embodiments of the invention there is provided an interchangeable unit comprising: a galvanic connector configured to interconnect with a corresponding galvanic connector of a base unit that is configured to connect to an empty light fitting; functional circuitry configured to provide additional functionality to the base unit wherein the additional functionality may be varied by interchanging the interchangeable unit, wherein the interchangeable unit and the base unit, when connected, enable communication between an environment adjacent to the light fitting and a data communications network.
For a better understanding of various examples of embodiments of the present invention reference will now be made by way of example only to the accompanying drawings in which:
In
Although the light fitting illustrated resembles a pendant fitting, any suitable light fitting 4 may be used.
The term galvanic connector is used to indicate a connector that closes an electrical circuit via an Ohmic (resistive) connection, as opposed to an inductive or capacitive coupling.
The Figure also illustrates an apparatus 10 which is configured to be received in the empty light fitting 4 and to provide for communication between an environment 6 adjacent to the light fitting 4 and a data communications network.
The apparatus 10 comprises: a galvanic connector 12, a network interface 16 and a communications interface 20.
The communications interface 20 is configured to enable communication between an environment 6 adjacent to the light fitting 4 and the network interface 16.
The network interface 16 is configured to operate as a node in a data communications network.
The galvanic connector 12 is configured to interconnect with the corresponding galvanic connector 3 of the empty light fitting 4. The galvanic connector 12 has the same size and dimensions as a galvanic connector (cap) of a standard lighting unit for the light fitting 4.
In this example, the apparatus 10 also comprises an illumination source 14 powered via the galvanic connector 12. The illumination source 14 provides a luminance flux similar to that of a standard lighting unit for the light fitting 4. For example, the illumination source may have a luminous flux greater than 100 lumens at a defined wavelength. For example, if the illumination source has a broad spectrum (e.g. it appears white) then the luminous flux may be greater than 100 lux at 555 nm. If the illumination source has a narrow spectrum (e.g. it appears as a particular color) then the luminous flux may be greater than 100 lux at a central wavelength of the narrow spectrum.
The illumination source 14 may, for example, comprise one or a plurality of light emitting diodes. Alternatively it may, for example, comprise a light bulb, a fluorescent lamp, a halogen lamp or any other illumination source.
In the illustrated example, the electrical power is provided as an alternating voltage to a transformer 18, which converts the alternating voltage to a direct current (DC) voltage before distributing the DC voltage to the illumination source 14, the communications interface 20 and the network interface 16. In some embodiments, the illumination source 14 may be supplied with power directly from the galvanic connector 12.
In other examples, the electrical power may be provided as a direct current (DC) voltage which is then distributed from the galvanic connector 12 to the illumination source 14, the communications interface 20 and the network interface 16.
The apparatus 10 may be provided with a user actuated control 11 that enables a user to controllably vary the luminous flux. For example, there may be different lux settings such as, for example, 100, 200, 300, 400 lux and the user may select one of the settings to control the luminous flux from the illumination source 14.
The communications interface 20 is a non-tactile interface in that communication is not via user touch.
The communications interface 20 may comprise an input interface 22 for data input. The input interface 22 is configured to communicate data dependent upon the environment 6 adjacent to the light fitting 4 to the network interface 16.

The communications interface 20 may comprise an output interface 24 for data output. The output interface 24 is configured to communicate data received from the network interface 16 into the environment 6 adjacent to the light fitting 4.
Referring to
The display device 24A may, for example, be a projector for projecting an image onto a surface spaced from the apparatus 10 such as, for example, an underlying table.
The audio output device 24B may, for example, be a loudspeaker. The loudspeaker may, for example, be optimized for teleconferencing.
The single wireless transceiver may provide reception for the input interface 22 and transmission for the output interface 24.
A wireless transceiver of the communications interface 20 may, for example, be configured to provide a network node in a local wireless network 32 (
As illustrated in

The apparatus 10 may be the source, or it may be the destination or it may be a node between the source and destination. The data may be transmitted as packet data. The network 30 may be a packet switched network.

The local wireless network may, for example, be a radio network that has a range of less than 100 m. The local wireless network may, for example, be a wireless local area network (WLAN), a Bluetooth piconet or another type of radio network.
Alternatively, the radio transceiver of the network interface 16 (if present) may, for example, be configured to provide a network node in a public wireless network 30. The public wireless network 30 may, for example, be a radio network that is shared by multiple users and typically has a range of more than 100 m. The public wireless network may, for example, be a cellular telephone network or a wireless large area network (WLAN).
The network interface 16 may use a unique network identifier. In the example of
The empty light fitting 4 is configured for interconnection with a standard lighting unit.
The galvanic connector 12 forms a “cap” or “base”. This provides for electrical contact and also physical retention.
In
The galvanic connector 12 is ‘male’ bayonet cap with one or more pins 11. The empty light fitting has a female L shaped slot 6 in its galvanic connector 3 and a spring 5.
The pin(s) 11 of the galvanic connector 12 are aligned with the slot(s) 6 of the light fitting 4 and pushed towards the light fitting 4 against the spring 5. When pin(s) 11 reach a base of the L shaped slot, the galvanic connector 12 (and the apparatus 10) is turned relative to the light fitting 4 to guide the pin across the base of the L shaped slot. The spring 5 presses the pin into a locking position at the end of the L shaped slot 6.
