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： A light source and method for controlling the same. The light source utilizes a light generator that generates a light signal of a wavelength at an intensity that is set by a control signal. The control signal is controlled by a servo that monitors the light output of the light generator and compares the monitored value with a target value. When the target value is changed, the control signal is initially replaced by a predicted control signal based on the new target value rather than the error signal generated in the servo. This provides time for the servo to adjust to the new target value. In one embodiment, the control signal includes a periodic signal that switches between a value that causes the light generator to generate light of the wavelength and a second value at which the light generator does not generate light of the wavelength.

摘要： A color management system for a field sequential lighting system. The color management system includes a plurality of light sources, a driver circuit, and a controller. The driver circuit is coupled to the plurality of light sources, and the controller is coupled to the driver circuit. The driver circuit drives the plurality of light sources. The controller generates first and second control signals for a first subframe of a temporal sequence of subframes. The first control signal corresponds to a first light source of a first color which is a primary color for the first subframe. The second control signal corresponds to a second light source of a second color which is a supplemental color for the first subframe. Embodiments of the color management system maintain a color point of the primary color of each subframe.

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： The present invention includes a light source having N light generators, a receiver, and an interface circuit. Each light generator emitting light of a different wavelength, the intensity of light generated by the kth generator is determined by a signal Ik coupled to that light generator. The receiver receives a color coordinate that includes N color components, Ck, for k=1 to N, wherein N is greater than 1. The interface circuit generates the Ik for k=1 to N from the received color components and a plurality of calibration parameters. The calibration parameters depend on manufacturing variations in the light generators. The calibration parameters have values chosen such that a light signal generated by combining the light emitted from each of the light generators is less dependent on the manufacturing variations in the light generators than a light signal generated when Ik is proportional to Ck for k=1 to N.

摘要： A system and method for generating white light involves using a combination of phosphor-converted white LEDs and non-phosphor-converted color LEDs to produce white light and adjusting the emitted light in response to feedback signals. Generating white light using a combination of phosphor-converted white LEDs and non-phosphor-converted color LEDs produces white light with an improved CRI and a wide SPD. Adjusting the emitted light in response to feedback allows luminance and chrominance characteristics of the white light to be controlled as the performance of the LEDs changes over time. The emitted light can be adjusted on a per-color basis and/or on a per-group basis, where a group of LEDs includes a combination of at least one phosphor-converted white LED and at least one non-phosphor-converted color LED.
