Abstract: A peak detection/digitization circuit includes a plurality of level detect units, each having a comparator and a flip-flop with a clock input responsive to the output of the comparator. For a detection period, each level detect unit configures a data output signal of the flip-flop to a first data state responsive to a start of the detection period. Further, each level detect unit is configured to enable the comparator responsive to the data output signal having the first data state or a second data state, respectively. While the comparator is enabled during the detection period, the level detect unit configures the data output signal of the flip-flop responsive to a comparison of an input signal to a corresponding reference voltage level by the comparator. The data output signals of the flip-flops of the level detect units at the end of the detection period are used to determine a digital value representative of a peak voltage level of the input signal.

Abstract: A pulse width modulation (PWM) signal generator generates a PWM signal having a specified effective PWM duty resolution for a corresponding cycle window. The PWM signal generator receives an N-bit value representing a duty to be implemented and sets values X and Y to the M least significant bits and the N-M most significant bits, respectively, of the N-bit value. The value M can be determined based on the value N and a maximum implementable frequency of a clock signal used to time the generation of each PWM cycle. The PWM signal generator generates a cycle window of 2M PWM cycles, each PWM cycle of the cycle window having a duty of either Y or Y+1. The number of PWM cycles in the cycle window having the duty Y+1 is based on the value X and the PWM cycles having a particular duty are contiguous within the cycle window.

Abstract: A power management technique in a light emitting diode (LED) system is disclosed. The LED system includes a plurality of LED driver connected in series, each LED driver configured to regulate the current flowing through a corresponding subset of a plurality of LED strings. Each LED driver determines the minimum tail voltage of the LED strings of the corresponding subset, compares the determined minimum tail voltage with an indicator of a minimum tail voltage of one or more other subsets provided from an upstream LED driver in the series, and then provides an indicator of the lower of the two tail voltages to the downstream LED driver. In this manner an indicator of the minimum tail voltage of the plurality of LED strings is cascaded through the series. A feedback controller monitors the minimum tail voltage represented by the cascaded indicator and accordingly adjusts an output voltage provided to the head ends of the plurality of LED strings.

Abstract: A rework method of a metal hard mask layer is provided. First, a material layer is provided. A dielectric layer, a first metal hard mask layer, and a patterned first dielectric hard mask layer have been sequentially formed on the material layer. There is a defect on a region of the first metal hard mask layer, and therefore the region of the first metal hard mask layer is not able to be patterned. After that, the patterned first dielectric hard mask layer and the first metal hard mask layer are removed. A planarization process is then performed on the dielectric layer. Next, a second metal hard mask layer and a second dielectric hard mask layer are sequentially formed on the dielectric layer.

Abstract: A distributed collaborative computer system is provided that comprises a plurality of server computers interconnected via a high-speed link. Client computers can connect to any available server computer and start or join a conference hosted on either the server computer to which the client computer is connected or any other server in the system. As a result, the system and method of the present invention is easily scalable to support an arbitrary number of participants to a conference by merely adding the appropriate number of server computers to the system. In addition, by replicating the conference information on more than one server computer, the single point of failure limitation is eliminated. In fact, if a server hosting or participating in a conference malfunctions, the failure is detected by other server computers and the client computer is able to reconnect to the conference through a new server computer.
