Abstract:
An automobile rear lighting includes a first emitter that emits a first light through a cover and a second emitter that emits a second light, different from the first light, through the cover such that an output light including the first light and the second light is emitted through the cover. The automobile rear lighting also includes a driving apparatus. The driving apparatus provides a first driving current to the first emitter and a second driving current to the second emitter. The driving apparatus adapts a magnitude of the first driving current and the second driving current based on at least one of at least one property of the cover or at least one optical component of the automobile rear lighting and a pre-defined color coordinates specification for the output light.
Abstract:
An imaging system includes multiple LED modules, a single image sensor, a controller, a processing unit and a depth map generator. Each LED module has a distinct angular emission profile and emits light having a distinct wavelength range. The image sensor detects light originating from at least two of the LED modules after reflection by an object in a field of view of the image sensor to provide an image sensor output. The controller controls the LED modules to turn on and off such that only one LED module emits light at a time. The processing unit processes the image sensor output to identify an intensity profile for the reflected light from each of the LED modules. The depth map generator determines an angular position of the object based at least on the intensity profile for the reflected light from each of the LED modules.

Abstract:
Methods and apparatus are described. A method, implemented in a wireless transmit/receive unit (WTRU) includes monitoring a first control channel search space (SS) associated with a first normal beam set comprising a first beam set. The WTRU initiates extended monitoring and monitors, subsequent to a trigger based on a measurement by the WTRU, a control channel SS associated with an extended beam set comprising the first beam set and one or more additional beam sets. The WTRU determines a second beam set from the extended beam set. The determination is based on a received control channel beam switch command or based on a control channel SS in which a beam switch command is received. The WTRU monitors a second control channel SS associated with a second normal beam set comprising the determined second beam set.

A method and apparatus for configuring a Long Term Evolution (LTE)-controlled Wireless Local Area Network (WLAN) interface for a wireless transmit/receive unit (WTRU) are described. A method includes receiving LTE Radio Resource Configuration (RRC) signaling that provides parameters for the WTRU to configure the LTE-controlled WLAN interface. The LTE RRC signaling includes a set of WLAN access points (APs), an indication that the WTRU is permitted to autonomously initiate association with a WLAN within the set, a type of one or more bearers to use for the LTE-controlled WLAN interface, WLAN-related security information, and a configuration for the WTRU to report a status of an association with a WLAN AP. The WTRU selects a WLAN AP to associate to from the list and initiates association to the selected WLAN AP using at least the WLAN-related security information.
