Title: Method for simultaneously slicing at least two cylindrical workpieces into a multiplicity of wafers
Inventor: HUBER ANTON
IPC: H01L21/78
Filed: 2007-10-25
Abstract: A method for simultaneously slicing at least two cylindrical workpieces with a multiplicity of wafers is provided to prevent damage of the wafer when a separation element is inserted by using a multi wire saw. A selection process is performed to select n-number of workpieces among workpieces having different lengths. The n-number of workpieces are sequentially fixed on a mounting plate(11) in a vertical direction and, simultaneously, intervals among the workpieces are constantly maintained. A mounting plate provided with the fixed workpieces is clamped on a multi wire saw. The multi wire saw slices the workpieces in a direction perpendicular to the vertical direction to form n-number of stacks(121,122,123) of a wafer(12) fixed on the mounting plate. The wafer fixed on the mounting plate is inputted into a wafer carrier(13) at two points on a circumference of the wafer spaced away from the mounting plate. A separation element is inserted into between the adjacent two stacks of the wafer and fixed on the wafer carrier. A coupling between the wafer and the mounting plate is released. The wafer is removed from the wafer carrier.

Title: Frequency error correction by using remodulation
Inventor: CHAPMAN JAMES
IPC: H04L27/00
Filed: 2005-09-09
Abstract: A communications signal is received through a propagation channel, down-converted in frequency and then converted into a digital signal. The samples of the digital signal are processed to estimate the information conveyed by the communications signal. The estimated information is then used with knowledge about the propagation channel. The result is compared with actual samples of the received digital signal to deduce phase errors in the digital signal. The phase errors are then used to deduce a frequency error in the digital signal that can be used to correct the samples of the digital signal and to correct the down-conversion process.

Title: Method and system for broadcasting multimedia data
Inventor: RACHWALSKI JON
IPC: H04L47/80
Filed: 2005-10-05
Abstract: A broadcast system provides support for clients to receive transmissions over a unicast or a multicast channel from a broadcast server. A server administrator configures each of a first server and client systems connected to the server to receive data in one of a multicast or unicast transmission mode. An empirical test determines whether an intervening network can support the configured mode and if not, transmission is performed using a fall back mode. The first server is able to provide access to data streams from other servers to the client systems connected thereto. Upon requesting a data stream from another server, the first server receives the data stream, replicates the data stream, transmits the data stream to the requesting client system and stores the replicated data stream for immediate access by any requesting client server connected thereto.

IPC: H02M3/335
Filed: 2005-10-13
Abstract: According to prior art, a clock frequency increase for clocked high-frequency integrated circuits, in particular microprocessors, reaches a current physical limit of approximately 3 GHz, as dynamic current modifications cannot be sufficiently compensated. The aim of the invention is to provide a power supply for electronic systems with a double-figure GHz range. To permit the rapid compensation of dynamic current modifications, the current compensation circuit (10) is placed in the vicinity of the integrated circuit (11) or is integrated into the latter. A control amplifier (8) influences a pulsewidth modulator (2) by means of an optical coupler (9). Said pulsewidth modulator control controls a normal mode voltage converter (3, 4) with synchronous rectification (5). A specific application area for the invention is the supply of future high-performance microprocessors, whose development has been delayed by the aforementioned power problem.
