摘要： A method for resetting and reenumerating a Universal Serial Bus (USB) device, an Electrical Fast Transient/Burst (EFTB) unit of a USB device for resetting and reenumerating the USB device and a USB device are described. In one embodiment, a method for resetting and reenumerating a USB device involves detecting a USB reset command from a host device at a USB device, setting a reset flag in the USB device in response to the detecting of the USB reset command, determining if the USB device is in a corrupted state in response to the reset flag, and causing a Single Ended Zero (SE0) signal to be issued to reset the USB device out of the corrupted state and reenumerate the USB device back to the host device if the USB device is determined to be in the corrupted state. Other embodiments are also described.

摘要： In one embodiment, a light measurement is acquired from each of a plurality of illumination zones. Each light measurement is digitized, and values derived from the digitized light measurements are stored, proximate to where the light measurements are acquired. The values derived from the digitized light measurements are then transmitted to a central control system, and light emitted by the illumination zones is regulated based on determinations made by the central control system. In some cases, the light measurements may be acquired and transmitted via a light sensor package having: a light sensor providing an analog output proportional to received light; an analog-to-digital converter to convert the analog output of the light sensor to a digital value; a memory to store a value derived from the digital value; and an addressable communication interface to transmit the stored value to an external control system.

摘要： Optical feedback for controlling color of light from a light source is provided. Incident optical energy of the light is detected as a function of discrete steps of wavelength. For each discrete step of wavelength, an X, Y and Z tristimulus subvalue is produced. All the X, Y and Z tristimulus subvalues for all the discrete steps are summed together to produce an X, Y and Z tristimulus value for the light. The X, Y and Z tristimulus values are used as feedback in controlling color of the light generated by the light source.

摘要： In one exemplary method, a mixed light is produced using first and second light sources of first and second colors. In one embodiment, the first and second light source are a white light source and a colored (e.g., red) light source. A determination is then made as to whether feedback tristimulus values, representative of the mixed light, are within a range of reference tristimulus values. If one or more of the feedback tristimulus values is out of range, a luminance ratio between the first and second light source is adjusted. In one embodiment, the mixed light is used as a backlight for a liquid crystal display.

摘要： A direct-firing backlight for a display is designed with a plurality of light emitting regions. Each of a plurality of light sensors is positioned to sense light produced by a corresponding one of the light emitting regions. A control system is operatively associated with the light sensors and light emitting regions. The control system receives information from the light sensors and, in response thereto, regulates light emitted from regions of a display. The regions of the display correspond to the light emitting regions of the direct-firing backlight. Various configurations of such a direct-firing backlight, and related methods, are also disclosed.
