Abstract: A body communication system (100) is provided which comprises a first device (110) and a second device (130). The first device (110) comprises a first body coupled communication interface (114) for forming a body communication network (170) via a body transmission channel (160) following a body of a user (150) when the first body coupled communication interface (114) is in a direct vicinity of the body of the user (150). The second device (130) comprises a second body coupled communication interface (134) for forming the body communication network (170) with the first device (110) via the body transmission channel (160) when the second body coupled communication interface (134) is in the direct vicinity of the user (150). The first and second body coupled communication interfaces (114, 134) communicate information with each other via the body transmission channel (160).

Abstract: The present invention relates to a light controller (102) configured to control a lighting system (100) for emitting light, comprising an image sensor (202) configured to capture an image of an activity area, and a control unit (200) configured to received the image, to detecting movement within the activity area, and to provide an activation signal for switching on a light source (104, 106, 108, 110) of the lighting system (100), wherein the control unit (200) is further configured to provide a deactivation signal for switching off the light source (104, 106, 108, 110) after a computed time period if no movement is detected within the activity area, the computed time period being based on a computed distance between a predetermined position within the activity area and a position of the latest detected movement within the activity area. The present invention provides advantages in relation to e.g.

Abstract: The present invention concerns LED drivers and is in particular directed to signal overlay for feature addition to an existing LED driver. Specifically, the invention is directed to an apparatus (200) for operating a LED driver (100), to a method of operating a LED driver, to a computer program for operating a LED driver and to a LED driver unit. The apparatus (200) is capable of overlaying an overlay signal (digital or analogue) to a control signal (164) of the LED driver (100) in dependence of external control information (256). The control signal (164) is provided to the LED driver at a control signal inlet (105). By overlaying the overlay signal, the apparatus (200) modulates the control signal (164) and provides a modulated control signal (164) to the same control signal inlet (105).

Abstract: A sensor device includes at least one autonomous streaming module. Predetermined internal events of the autonomous streaming module or predetermined external events from streaming data at an interface to a smart shell of the autonomous streaming module are detected. An operational mode of a component or subsystem within the smart shell of the autonomous streaming module is controlled in response to the detection.

Abstract: A processing element (1) forming part of a parallel processing array such as SIMD comprises an arithmetic logic unit (ALU) (3), a multiplexer (MUX) (5), an accumulator (ACCU) (7) and a flag register (FLAG) (9). The ALU is configured to operate on a common instruction received by all processing elements in the processing array. The processing element (1) further comprises a storage element (SE) (11), which supports the processing of local customized (i.e. data dependent) processing in the processing element (1), such as lookup table operations and the storing local coefficient data.

Abstract: An image processing apparatus (400) comprises a SIMD processor (401) which scans an image frame for regions of interest (step 301), for example corresponding to regions having objects or lines of interest. Each region of interest is rescanned to an orthogonal grid. The orthogonal grids are then floorplanned so that they are rearranged into a smaller subset of image lines. The floorplanning consists of mapping a set of rectangles into a compressed frame portion. Optionally, the rectangles can be rotated in order to allow the rectangles to be packed more densely. The SIMD processor (401) then processes the floorplanned image data (step 307). Once the image data has been processed by the SIMD processor, the DSP (405) re-associates the processed data (step 309), using information stored during floorplanning. The image processing apparatus results in a more efficient use of the SIMD processor (401).
