Abstract: A dimmer control system has a communication control loop that connects a master unit in series with a plurality of remote units, and it is superimposed in series on the dimmer load line so as to allow two-way communication between the master unit and remote units without affecting the operation of the load. Communications from the master to the remote units are encoded in loop current fluctuations, whereas communications from any remote to the master unit are encoded in loop voltage fluctuations. The master unit has a switched power supply, for use during normal LOAD ON operation, in tandem with a capacitive power supply, for use during LOAD OFF operation of the control units so as to minimize hum. The master unit power supply circuit provides an output rail voltage comprised of a reference voltage for the load superimposed with a control loop voltage for the voltage drop across the series-connected remote units. The master unit has a POWER OFF detection circuit and a non-volatile memory for storing system status information, so that when power is restored, the system can be restored to its former power level. The switch units are formed with a cover frame mounting a switch plate on a hinge axis allowing ON/OFF movement of an opposing side thereof. An array of LED light pipes is mounted in the switch plate aligned with the hinge axis, in order to minimize displacement of the light pipes during actuator movement.

Title: Method for limiting amplitude of a carrier frequency output signal
Inventor: JELONNEK BJOERN
IPC: H04B1/04
Filed: 2003-04-01
Granted: 2012-01-17
Abstract: The invention concerns a method for forming a carrier frequency output signal from n partial signals of a basic frequency band. Each of the n partial signals is attributed as input signal to a representative main branch, wherein the corresponding partial signal is limited in amplitude, filtered and converted into an intermediate frequency partial signal. As output signals of the main branch, the n partial signals are assembled into a common sum signal.  Said sum signal is limited in amplitude, subjected to a digital-analog conversion and converted into a frequency carrier output signal. Moreover, each partial signal reaches an auxiliary branch, whereby probable signal increased heights of the partial signal can be determined as estimated values.  Using said estimated values, the amplitude limitations of the corresponding partial signals, executed in the main branch, can be regulated in said branch.
