A device comprising: an input for receiving images captured by a camera, of an environment illuminated by light from a light source; an image processing module; and a verification module. The image processing module is configured to process one or more of the images to decode a timestamp modulated into the light, and to output an indication of the decoded timestamp. The verification module is arranged to receive the indication of the decoded timestamp output by the image processing module, and based thereon to perform an at least partially automated verification of a time at which the one or more images were captured.

Verification of images captured using a timestamp decoded from illumination from a modulated light source

The disclosure relates to the control of a lighting system illuminating a space such as a room. The controller receives signals from a mobile user terminal, including an indication of a user input entered by a user via an on-screen user interface of the mobile user terminal. The controller is also able to determine a position from which the user input was entered by the user. Further, each of a plurality of discrete control policies is associated with a respective positional demarcation within the space in question, where each control policy defines a respective type of response of the illumination to one or more on-screen elements of the lighting-control user interface. Based on this association, the controller selects one of the control policies associated with the determined position. The controller then controls the lighting system to provide the illumination in accordance with the response defined by the selected control policy.

Controlling a lighting system using a mobile terminal

A controller, method and program for controlling one or more sources of a utility to provide the utility into a space occupied by one or more users, e.g. for controlling light sources illuminating an indoor or outdoor space. An input from one or more sensors is processed to detect motions of a user in the space, to detect that the motions correspond to predetermined gestures performed by the user, and to detect a position from which each gesture was performed. Further, each of a plurality of discrete control policies is associated with a respective combination of predetermined gesture and positional demarcation within the space. Each control policy defines a respective response of the utility to the respective associated gesture. For gestures performed from each of a plurality of different positions, a different control policy is selected based on being associated with the detected gesture and detected position.

Gesture based control of a utility

A lighting system () and a method of protecting a lighting device of a lighting system against theft are provided. The lighting system comprises a lighting device () and at least one other device (). Both the lighting device and the at least one other device comprises a data storage (), a controller () and a network interface (). The lighting device additionally comprises a light emitter (). When the lighting device powers up, the other device transmits a verification value stored in its data storage to lighting device. The lighting device assesses the verification value in relation to a unique value stored in its data storage to check whether the lighting system knows the lighting device. In dependence of the assessment, the lighting device is controlled to operate in a first or in a second operational mode. In a commissioning procedure the other device may receive the verification value for storage in its data storage.

Lighting device and a method of protecting a lighting device

An apparatus comprises a controller and an input for receiving a signal from a microphone. The controller processes the signal from the microphone to detect a sound associated with the use of a consumable by a user, and generates an output in response to detecting that sound. For example the consumable may be pre-packaged and the sound may be associated with the packaging. In embodiments the controller controls ambient lighting in response to the sound of a first action (e.g. opening the cap of a container), and controls task lighting in response to the sound of a second action (e.g. dispensing the product from the container). In another embodiment the controller detects a sound indicative of the consumable running out (e.g. the hollow sound of the container being put down on a surface), and in response generates a visible indicator or transmits a signal over a network.
