摘要： The invention refers to an apparatus (130) for configuring a radiofrequency sensing of a radiofrequency sensing network (100) comprising network devices (121, 122, 123), e.g. luminaires, wherein the network is adapted to perform radiofrequency sensing in a first (101, 201 301) and second area (102, 202,. 302) separated by a physical separation (126, 330). The apparatus comprises a providing unit (131) determining a first baseline and a second baseline, wherein the first/second baseline is associated with the first/second area, respectively. The first/second baseline enable a radiofrequency sensing of events in the second area by the network devices. A configuration unit (132) is adapted to configure the radiofrequency sensing to differentiate between events originating from the areas based on the baselines. This allows the present invention to provide an apparatus that allows for a more accurate and reliable 10 radiofrequency sensing in a predefined sensing area.

摘要： A power beaming system includes a power beam transmitter arranged to transmit the power beam, and a power beam receiver arranged to receive the power beam from the power beam transmitter. A power beam transmission source is arranged to generate a laser light beam for transmission by the power beam transmitter from a first location toward a remote second location. A beam-shaping element shapes the laser light beam, at least one diffusion element uniformly distributes light of the shaped laser light beam, and a projection element illuminates a power beam receiving element of predetermined shape with the shaped laser light beam. At the power beam receiver, a diffusion surface diffuses a portion the power beam specularly reflected from the power beam receiver.
