Abstract: A substrate support includes an edge ring, a heater element arranged within the edge ring, a ceramic layer, at least one heating element arranged within the ceramic layer, and a cable configured to provide power from a power source to the heater element and the at least one heating element. The cable includes a first plurality of wires connected to the heater element, a second plurality of wires connected to the at least one heating element, a filter module, and an isolation device connected only to the first plurality of wires between the filter module and the heater element. The first and second pluralities of wires are twisted together within the filter module. The isolation device is configured to compensate for a resonance frequency generated during operation of the heater element and the at least one heating element.

Abstract: This document discusses, among other things, an impedance detection circuit, method, and integrated circuit, comprising a ramp-up current generation circuit and an impedance determining circuit, wherein the ramp-up current generation circuit is configured to input a ramp-up current including n breaks to a port of a device where the ramp-up current generation circuit is disposed, to which port an external device is connected, and wherein the impedance determining circuit is configured to detect an impedance of the external device in each break time period of the ramp-up current input by the ramp-up current generation circuit until the impedance of the external device is acquired by detection in the last break time period of the n breaks.

Abstract: This document discusses, among other things, a detection circuit configured to receive an output of a window comparator over a range of input values and to measure a difference between first and second thresholds of the window comparator, and a trim circuit configured to adjust at least one of the first or second thresholds using the measured difference between the first and second thresholds.

Abstract: An apparatus comprises a connector configured to receive an electrical contact of an accessory device that is electrically coupled to a resistor of the accessory device, a current source configured to apply a specified current to the resistor to generate a resulting voltage, a comparator configured to receive and compare the resulting voltage to a reference voltage, and a controller configured to store an outcome of the comparison as a bit in a register, to adjust the applied current using the outcome of the comparison, and to determine a resistance value for the resistor using the bit stored in the register.

Abstract: A method for centrally creating a schedule for a group of company employees who may be geographically dispersed. The system operates over a distributed network thereby providing communication among employees and other data sources. The scheduling system assigns the employees to shifts while accommodating numerous factors including staffing requirements, employee preferences, and optimal settings based on forecasting. Forecasts derived from information concerning factors outside the company constitute extrinsic influences on the schedule generated according to the invention.
