摘要： A wireless power transfer system includes a power transmitter (101) providing power to a power receiver (105) via an inductive power signal. The power transmitter (101) and receiver (105) can operate in different modes including a test mode and a power transfer mode. Operating parameters of the power receiver (105) are constrained in the test mode relative (and specifically the loading). A foreign object detector (209) generates a foreign object detection estimate from a comparison of a measured load to an expected load of the inductive power signal when the power receiver is operating in the test mode. A controller (211) enters the power transmitter (101) and receiver (103) into the power transfer mode when the foreign object detection estimate is indicative of no detection of a foreign object. In the power transfer mode, a parasitic power loss detector (207) generates a parasitic power loss detection for the power transfer if a parasitic power loss estimate is outside a range.

摘要： To enable a good HDR image or video coding technology, being able to yield high dynamic range images as well as low dynamic range images, we invented a method of encoding a high dynamic range image (M_HDR), comprising the steps of: - converting the high dynamic range image to an image of lower luminance dynamic range (LDR_o) by applying a) scaling the high dynamic range image to a predetermined scale of the luma axis such as [0,1], b) applying a sensitivity tone mapping which changes the brightnesses of pixel colors falling within at least a subrange comprising the darker colors in the high dynamic range image, c) applying a gamma function, and d) applying an arbitrary monotonically increasing function mapping the lumas resulting from performing the steps b and c to output lumas of the lower dynamic range image (LDR_o); and - outputting in an image signal (S_im) a codification of the pixel colors of the lower luminance dynamic range image (LDR_o), and - outputting in the image signal (S_im) values encoding the functional behavior of the above color conversions as metadata, or values for the inverse functions, which metadata allows to reconstruct a high dynamic range image (Rec_HDR) from the lower luminance dynamic range image (LDR_o).

摘要： A thermal barrier for a wireless power transfer system comprises a first surface area (807) for coupling to a power receiver (111) to be powered by a first electromagnetic signal and a second surface area (805) for coupling to a power transmitter (101) providing a second electromagnetic signal. The thermal barrier (801) further comprises a power repeater (803) with a resonance circuit including an inductor and a capacitor. The power repeater (803) is arranged to generate the first electromagnetic signal by concentrating energy of the second electromagnetic signal towards the first surface area (807). The thermal barrier may provide thermal protection of the power transmitter (101) without unacceptable impact on the power transfer operation.

摘要： To enable better encoding of the currently starting to appear high dynamic range images for use in full high dynamic range technical systems (containing an HDR display, and e.g. in an HDR grading application), we invented a method of constructing a code allocation function for allocating pixel colors having pixel luminances to codes encoding such pixel luminances, in which the step of determining the code allocation function to be applied to at least one color coordinate of the pixel to obtain a code value, comprises constructing that function out of at least two partial functions, and similar methods at a receiving side, and apparatuses, and signals for communicating between the two sites.

摘要： A wireless power transfer system includes a power transmitter (101) arranged to provide a power transfer to a power receiver (105) via a wireless inductive power signal. A parasitic power loss detector (207) is arranged to detect a parasitic power loss for the power transfer, and a user indicator (209) is arranged to initialize a user alert in response to the detection of the parasitic power loss. The system comprises an input (211) for receiving user inputs; and a controller (213) which is arranged to initiate an adaptation of a parasitic power loss detection operation performed by the parasitic power loss detector (207) to detect parasitic power losses if a user input meeting a criterion is not received. Each of the individual features may be implemented in the power transmitter (101), the power receiver (105), or may e.g. be distributed between these. The approach may allow improved foreign object detection in a wireless power transfer system.

摘要： A wireless power transfer system includes a power transmitter (101) arranged to provide a power transfer to a power receiver (105) via a wireless inductive power transfer signal where the power transfer signal is provided in a power time interval of a repeating power transfer signal time frame. The time frame furthermore comprises a reduced power time interval. An apparatus (typically being the power receiver (105) or the power transmitter (101)) comprises a short range communication unit (305, 405) arranged to communicate data messages with a second entity (which is the complementary unit, i.e. either the power transmitter (101)) or the power receiver (105)) using short range communication. The short range communication has a range not exceeding 20 cm. The apparatus further comprises a synchronization unit (309, 409) arranged to synchronize the short range communication to the power transfer signal time frame such that short range communication is restricted to the reduced power time intervals. The communication may specifically be NFC communication.
