摘要:
A device-under-test card includes a matrix of fuses and/or antifuses formed as part of a multi-layered structure. The matrix of fuses and/or antifuses can be electrically programmed to connect any one of first electrical contacts to any one of second electrical contacts and so allows the device-under-test card to act as a junction between burn-in board traces couplable to signal drivers and/or receivers and burn-in board traces couplable to terminals of a device-under-test. The device-under-test card also includes a discrete resistor or alternatively a resistor ladder that permits a terminal of a device-under-test to be coupled to a power or ground terminal or to any combination of resistances including a short, in addition or as an alternative to any one of various signal drivers and/or receivers.

A system and method for automatically analyzing and characterizing Internet search results and annotating a search results page according to specific characteristics of each webpage located at a URL corresponding to a search result. Such characteristics include the composition of each search results webpage as well as which search term elements are present in a webpage located at a URL corresponding to a search result out of those search term elements that were submitted to a search engine to produce the search results webpage. Further, search results are annotated to indicate which search term elements are present in a descendent webpage of a webpage located at a URL corresponding to a search result. Search results may also be optionally filtered according to specific characteristics of a webpage located at a search results URL such that certain categories of webpage are excluded from being referenced in the displayed search results.

Systems and methods are disclosed for tracking the progress of a trip where a person or persons wish to have a third party automatically informed of a delayed return. For long duration trips and/or trips to distant destinations, people typically make provision for having their pets and/or children watched over. However for short trips, they typically do not, especially with respect to their pets. The disclosed methods provide monitoring of a trip's progress such that if a traveler doesn't return home by a certain time, a third party is notified, thus avoiding a prolonged period of time wherein the pets and/or children are unattended, especially in the event of a catastrophic accident. The third party may be notified if an arrival time is predicted to be delayed, and when an actual arrival occurs. Provision is also included for adjusting the trip duration to delay or advance a designated arrival time.

Systems and methods are described for remote control of a media server computer from a controller device, typically a laptop computer, where remote operation of the media server, including the selection of videos and other digital media may be performed from the controller while normal TV programming (cable, satellite, or broadcast) is viewed on the TV. Other embodiments describe background operations performed on the controller device, the media server, or both, such that new videos may be located on the web or locally on the LAN while a current video is playing on the media server and viewed on the TV. Methods are also described for more reliably establishing network connections between the controller and media server, and systems and methods are described for implementing a multi-video display on the media server where videos to be displayed on the media server are displayed on and selected by a controller device.
摘要:
A binning method is disclosed for measuring semiconductor devices for certain parameters and placing specific devices into different categories or “bins” according to the measured parameters. Measurable parameters include performance/speed-grading, power consumption, current leakage, and the ability to operate at certain temperature extremes. A method for speed grading semi-custom ASIC devices is specifically described that does not require removing partially completed wafers from the fab line for testing. To speed-grade a new boat of partially completed un-customized wafers, a small number of wafers (1 or 2) are processed to completion while being customized specifically for a customer design requiring only the slowest bin. These wafer(s) are then performance tested and the remaining wafers in the boat are certified according to these results for their performance level and placed in a wafer bank for later use.
摘要:
To serve prototype and initial production requirements, an emulation solution is described where an ASIC semiconductor device die containing primarily fixed functions, for example a DSP processor with programmable instruction interface, is mounted in the same package as a conventional FPGA device—the FPGA in this example implementing custom instructions for DSP algorithm acceleration and connecting primarily to the fixed function device. A fully integrated, single die ASIC solution is then available for migration of designs to higher volume production where some of the field programmable function will be replaced with fixed function. The base wafer for the ASIC device used in the prototype package and base wafer for the volume production ASIC device may be the same.
摘要:
A programmable logic array (PLA) in accordance with the invention achieves a maximum amount of depopulation of programmable connections while still implementing a logic function and maintaining flexibility for future reprogramming. In addition, a PLA in accordance with the invention can be built so that no matter what functionality is programmed, performance characteristics for the device are maintained. Further, a PLA in accordance with the invention does not require a regular array structure.
摘要:
A new circuit architecture is provided for testing digital integrated circuits which allows one to arbitrarily force any combination of logic values to be simultaneously driven onto any combination of internal nets. This allows all of the connections to each internal logic cell, and the logic cell itself, to be verified by applying a set of test patterns to each logic cell individually. In this way, the integrity of the entire device can be verified without having knowledge of the operation of the circuit as a whole.

A printed circuit board includes an array of conductive pads including component-mounting holes disposed on first and second surfaces thereon. An array of conductive attachment lands arranged in pairs of first and second attachment lands are disposed on the first and second surfaces. The first and second attachment lands are insulated from one another and separated by a distance selected to allow attachment of standard sized components therebetween on the first and second surfaces of said circuit board. First and second conductive power distribution planes are disposed on the first and second surfaces and are insulated from the conductive pads and the second attachment lands disposed thereon. The first attachment land of each pair on the first surface of the circuit board is electrically connected to the first power distribution plane and the first attachment land of each pair on the second surface of the circuit board is electrically connected to the second power distribution plane, and the second attachment land of each pair on the first and second surfaces of the circuit board electrically connected to one of the conductive pads.
摘要:
An absolute encoding system is provided based on an incremental optical encoder which, together with a low power circuit technology and means for pulsing the light emitter(s) of the encoder (normally the largest power consuming device(s) in such a system) with a signal of low duty cycle and means for sampling the light detector outputs during the appropriate period of response to the emitted light pulses, produces an encoder system having extremely low internal power consumption allowing not only data retention but also data acquisition during periods of isolation from an external power supply by relying on its own relatively small battery-based power source.
