CPC Class H04N

Embodiments of the present application provide a laser light source and a laser projection device. The laser light source includes a laser assembly and a light combination mirror assembly. The laser assembly includes at least a laser, a light emitting surface of the laser has a plurality of light emitting regions, and beams emitted from different ones of the plurality of light emitting regions are in different colors. The light combination mirror assembly includes a plurality of mirrors that are sequentially arranged along an optical transmission path of the laser, with each of the mirrors corresponding to one of the light emitting regions. The light combination mirror assembly is used to converge the beams in different colors emitted from the laser to form a white beam.

A mobile device includes a camera and a light source module embedded in the mobile device. The light source module includes at least a laser-pumped phosphor light source that includes a photoluminescent phosphor and a laser diode to generate laser light within a first wavelength range to pump the photoluminescent phosphor. Exposure of the photoluminescent phosphor to the laser light results in emission of visible light within a second wavelength range according to a laser-pumped emission spectrum associated with the photoluminescent phosphor.

A wireless power transmitting device according to an embodiment may include a power transmission circuit and a processor. The processor may be configured to control the power transmission circuit to wirelessly transmit power to a first area around the wireless power transmitting device, perform a predetermined first operation when an obstacle is detected in a second area around the first area, and perform a predetermined second operation when it is detected that the obstacle has entered the first area.

An image display apparatus is disclosed. The image display apparatus includes a signal processing device having a transceiver that includes a current sweep circuit configured to output a plurality of sweep currents, a current selector connected to the current sweep circuit and configured to select a predetermined current from the plurality of sweep currents based on comparison with a reference voltage, and a comparator configured to compare a voltage output from the current selector with the reference voltage. Accordingly, a constant output voltage level can be obtained.

A programmable logic circuit device includes: a processor; and plural reconfiguration regions each including a circuit configured by change of connection between elements, wherein the processor is configured to: receive designation of a processing group including a series of plural kinds of processing; acquire management data decided for each processing group, the management data designating plural pieces of reconfiguration data each designating connection between elements in a corresponding one of the plural reconfiguration regions so that the designated processing group is performed; acquire the plural pieces of reconfiguration data designated by the acquired management data; change connection between elements in the plural reconfiguration regions in accordance with the designation by the acquired plural pieces of reconfiguration data; and when connection between elements is changed in accordance with designation by the plural pieces of reconfiguration data, in a case where designation by at least one of the acquired plural pieces of reconfiguration data does not require change of connection in a corresponding one(s) of the plural reconfiguration regions, use same reconfiguration data as that used to connect the elements in the corresponding one(s) of the plural reconfiguration regions.

The present invention relates to a device and a method for performing channel selection in a wireless AV system. Such present specification discloses a wireless data transmission device for performing channel selection, the device comprising: a communication unit for performing the steps of selecting an initial channel in a non-connection state on the basis of first channel monitoring, transmitting a periodic beacon onto the initial channel in a standby mode after switching to a connection state, and selecting a new channel in the standby mode on the basis of second channel monitoring in an interval in which beacon transmission does not occur; and a processor connected to the communication unit so as to control the operation of the communication unit. Fast and economic channel selection appropriate for the wireless AV system is possible.
