A lighting system and method are provided for controlling a PWM duty cycle. The lighting system is provided with at least one device that is configured to emit light in response to receiving electrical power. The lighting system includes a power circuit and a feedback circuit. The power circuit is configured to selectively supply power to the device at a duty cycle corresponding to a first mode and a second mode, wherein the duty cycle of the first mode is less than 10% of the duty cycle of the second mode. The feedback circuit is configured to provide a feedback signal that is indicative of the energy provided to the device. The power circuit is further configured to disable power to the device during the first mode in response to the energy being greater than a threshold energy value, thereby adjusting the duty cycle.

Lighting system and method for PWM duty cycle control

A light control system having a light emitting device to produce a pre-determined light output is disclosed. The light control system includes a power circuit in electrical communication with the light emitting device for transmitting an electrical current to the light emitting device for controlling the light output, a timing circuit in electrical communication with the power circuit, wherein the timing circuit generates a pre-determined timing sequence and regulates a duty cycle of the power circuit in response to the timing sequence, and a feedback circuit in communication with the light emitting devices and the timing circuit, wherein the feedback circuit is adapted to monitor an electrical characteristic of the light emitting devices and control the timing sequence of the timing circuit in response to the electrical characteristics of the light emitting devices.

Cavities within structural members of a motor vehicle or other structure are used for propagation of wireless RF communication signals. The system is particularly adapted for use in structures wherein permanent, fixed transmission guides can be easily provided, and it is especially useful in motor vehicles where it 1) reduces the cost and power requirements of electronic modules using wireless communication, 2) shields the communication channel from outside electromagnetic interference, and 3) allows the propagation of emissions to be substantially restricted to desired regions away from people and electronic devices not in the intended network.

Low power, high speed data communications in vehicles

A method for identifying image data bits, especially where the image data is to be reliably co-identified with collateral document has been disclosed. Such &ldquo;identification-bits&rdquo; should be carried with the image data through various stages of processing, so the image's identity can be maintained at each processing station, and can be transferred to a downstream processing station. A salient object hereof is to identify image data; especially with &ldquo;sync bits&rdquo;.

Check Reading apparatus and method utilizing sync tags for image matching

An arrangement for extracting and processing image data to form an array of re-scaled pixel data, this arrangement being part of a Normalizer/Scaler stage in an image lift/processing system, and including: a scaler for storing N different selectible scaling algorithms; a scaler-output; an input for receiving scanned lines of pixel data and feeding it sequentially line-by-line, pixel-by-pixel to the scaler, the input including 'scale factors' for selecting an algorithm; while the scaler includes a mapping stage for executing a two-dimensional mapping of adjacent pixel values and adjacent scanline values; this arrangement also including a command store for storing scaling algorithms, with a command register input for the scale factors. Preferably the scaler also includes a First ROM for storing pixel values at prescribed addresses; a Second ROM for similarly storing previous pixel values, being input in parallel with the First ROM; a Latch to which the ROMs are output; and a pixel Counter reset with each new scan line; with a 'current pixel' value input to a prescribed address in the First ROM, along with a 'pixel count' number from the Counter, plus an associated scale factor; with an Adder interposed between the ROMs and the Latch to execute addition mapping.
