摘要： A high resolution pulse width modulation (PWM) or voltage controlled output (DCO) generator is disclosed. The resolution is increased over that of the circuit clock by delaying the generated signal through a series of delays, all of which are controlled by a delay locked loop. The delays are a small fraction of the clock period, thus providing resolution greater than that of the circuit clock.

摘要： A method for associating a group of lighting units in a wireless-controlled lighting system to respective buttons or other control elements on a remote control. Each of the lighting units transmits, via modulation of its own illumination light, a unique identification code for the respective unit. The remote control is successively positioned to receive the modulated light from each lighting unit and, at each position, the user activates a respective control element of the remote control for association with the lighting unit. The remote control then transmits to a control master for the group the unique codes and codes identifying the respective control elements with which they have been associated.

摘要： A multi-mode modular pulse-width-modulator capable of outputting low-speed and high-speed control signals is presented. The operation of the modulator is determined by parameters that are stored within the modulator and provide for high-speed updating and control capability in response to changes in voltage or current. In one mode, an update and control signal is generated based on timing parametric data stored in a local memory. In a second mode, an update and control signal is generated based on timing parametric data that provided by an external input device. Furthermore, control variables are also stored locally which control the position of switches, which alter signal paths within the modulator.
