Abstract: A multi point contactor (MPC) on a component testing system for electrically contacting a terminal on a device under test (DUT) includes at least three independently moveable contacts to help insure at least two of them contact the DUT terminal. At least one of the contacts includes an integral spring, preferably in the form of a blade laser machined from a sheet of electrically conductive material to include a first portion for bearing against the contact-holding structure, a second portion for bearing against the terminal on the DUT, and a third portion interconnecting the first and second portions that functions as an integral spring bias for spring biasing the second portion from the first portion toward the terminal on the DUT. Preferably, the third portion of the blade has a serpentine shape that consistently results in desired constant-force spring characteristics over a nominal range of blade travel.

Abstract: A method for controlling the flow of information between a UE and a Node B is provided. The UE transmits over a control channel to the Node B a signal requesting to transmit information to the Node B. The UE then receives over a shared channel from the Node B a signal identifying a time at which the UE is permitted to transmit information. Thereafter, the UE transmits at the identified time over a data channel to the Node B a signal containing the information.

Abstract: The present invention is a general mode of a pixel-based adaptive blending method. By receiving several different input signals to generate a pixel and a blending factor of each signal, an output pixel can be generated depending on these pixels and blending factors. Thus, several different video and graphic images can be overlapped and blended flexibly on an output display.

Abstract: A telephone includes a transmit channel and a receive channel, each including a bank of sub-band filters having a VAD coupled one to each sub-band filter. Each VAD measures the spectral energy in a sub-band, compares the spectral energy to a first threshold, and produces an output signal representative of whether or not the first threshold is exceeded. The voice activity detector also includes a threshold circuit for calculating a dynamically adjustable noise threshold based upon averaged measured spectral energy. A wide band or system VAD monitors echo canceling circuitry to detect voice activity and double talk. A dynamic balance control circuit maintains the transmit and receive channels in a predetermined energy ratio during double talk.

Abstract: Low cost antennas formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises conductor fibers or conductor particles in a resin or plastic host wherein the ratio of the weight of the conductor fibers or conductor particles to the weight of the resin or plastic host is between about 0.20 and 0.40. The conductive fibers can be stainless steel, nickel, copper, silver, or the like. The antenna elements can be formed using methods such as injection molding or extrusion. Virtually any antenna fabricated by conventional means such as wire, strip-line, printed circuit boards, or the like can be fabricated using the conductive loaded resin-based materials. The conductive loaded resin-based material used to form the antenna elements can be in the form of a thin flexible woven fabric which can readily cut to the desired shape.

Abstract: A circuit is provided having a secondary semi-analog FIR filter connected to a primary filter via a coefficient to reduce the size of the sizes of the resistors used in the primary filter. The coefficient may be one or more intermediate resistors connected between separate resistor/voltage driver banks that make up the FIR filter. The result is a circuit that takes up less chip space required to accommodate the required resistance for a digital to analog converter (DAC). The invention configures the resistor structure to produce the same output result as a conventional circuit, but with smaller resistor values that take up less surface area on the chip.

Abstract: Methods for the determination of center of focus and process control for a lithographic tool. Diffraction signatures are obtained from a plurality of diffraction structures located within multiple different focus setting fields. Variability of diffraction signatures with each field are determined, by direct analysis or comparison to a library. The variation or uniformity may be represented by any measure, including the standard deviation or the range of values of a chosen feature of a library of theoretical diffraction structures or the variability or uniformity of the diffraction signatures themselves, such as by RMS difference or intensity range. The methods may be used for process control and monitoring of focus drift by determining intra-field variation of diffraction signatures of multiple diffraction structures in a series of wafers.

Abstract: A torque transmitting system supports rotational and lateral movement of a drive shaft. The system includes translating inner and outer tubes which have aligned canals for placement of a ball bearing and a pinion shaft to couple the tubes to a drive system. Rotational torque is transferred from the pinion shaft, to the outer tube and, through the ball positioned in the aligned canals, to the inner tube and then to the drive shaft. Furthermore, the ball engaged in the canals defines a range of motion in which the inner tube is slidable with respect to the outer tube, along the tubes' longitudinal axis, to permit advancement of an attached drive shaft.

Abstract: A method for monitoring a subject can include acquiring data from the subject, and dynamically adjusting an alarm limit based on the data. The method can also comprise determining a first value that is typical for the subject for the characteristic being monitored, determining a second value for the characteristic being monitored, and generating a comparison based on the two values. The method could also comprise setting a threshold for a characteristic being monitored, and decreasing the alarm limit if the data crosses the threshold. The method could also include setting an extremity limit. The following methods can be applied to the monitoring of a healthcare patient, or other subjects of interest. Also, the values used in the monitoring of the subject can be configured to be transferable from one monitor to another.
