Abstract: A cross reality system enables any of multiple devices to efficiently access previously stored maps. Both stored maps and tracking maps used by portable devices may have any of multiple types of location metadata associated with them. The location metadata may be used to select a set of candidate maps for operations, such as localization or map merge, that involve finding a match between a location defined by location information from a portable device and any of a number of previously stored maps. The types of location metadata may prioritized for use in selecting the subset. To aid in selection of candidate maps, a universe of stored maps may be indexed based on geo-location information. A cross reality platform may update that index as it interacts with devices that supply geo-location information in connection with location information and may propagate that geo-location information to devices that do not supply it.

Abstract: A door lock includes a case mounted in a door and an inside handle mounted to an inner side of the door. A latch bolt is operably connected to the inside handle and movable between an extended, latching position and a retracted, unlatching position. A spring device is mounted to a deadbolt for biasing the deadbolt from a retracted, unlocking position toward an extended, locking position. A positioning member engages with and retains the deadbolt when the deadbolt is in the retracted position. An auxiliary bolt is operably connected to the positioning member and movable between an extended position and a retracted position. The auxiliary bolt disengages the positioning member from the deadbolt when the auxiliary bolt is in the retracted position such that the deadbolt is moved to the extended position by the spring device.

Abstract: The present invention relates to a method and apparatus universal serial bus (USB) physical layer. An UTM interface control logic receives a transmit data packet of USB 2.0 transceiver macrocell interface (UTMI). A transmit first-in first-out (FIFO) unit receives the transmit data packet output from the UTM interface control logic. A transmit unit receives the transmit data packet output from the transmit FIFO. An analog front-end (AFE) receives the transmitted data packet output of the transmit unit. A receive unit receives a receive data packet output from the AFE. A receive FIFO receives the receive data packet output from the receive unit and connected to the UTM interface control logic, whereby the receive data packet is output to the USB 2.0 transceiver macrocell interface.

Abstract: A light-emitting diode with a micro-lens layer, includes a die substrate, a second epitaxy layer deposited on the top surface of the die substrate, a first epitaxy layer deposited on a portion of the top surface of the second epitaxy layer, a second electrode formed on a portion of the top surface of the second epitaxy layer, a first electrode formed on a portion of the top surface of the first epitaxy layer, and a micro-lens layer mounted on a portion of the top surface of the first epitaxy layer. The micro-lens layer can change the projection angle and the projection path of the light beams radiated within the light-emitting diode in virtue of the diffusion effect caused by the micro-lens, and thereby improving the light-drawing efficiency and the luminance of the light-emitting diode.
