摘要： A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design for scheduling the servicing of data requests, using the variable latency mode, in an FBDIMM memory sub-system is provided. A scheduling algorithm pre-computes return time data for data connected to DRAM buffer chips and stores the return time data in a table. The return time data is expressed as data return time binary vectors with one bit equal to “1” in each vector. For each received data request, the memory controller retrieves the appropriate return time vector. Additionally, the scheduling algorithm utilizes an updated history vector to determine whether the received request presents a conflict to the executing requests. By computing and utilizing a score for each request, the scheduling algorithm re-orders and schedules the execution of selected requests to preserve as much data bus bandwidth as possible, while avoiding conflict.

摘要： A method for generating reliability tests for a telephone system is based upon sampling an orthogonal array which covers various combinations of test parameters. Field data is collected of actual telephone activity on a telephone system. The field data is evaluated so as to determine call-mix characteristics. Probabilistic weights for the different call-mix characteristics are obtained, and then the probabilistic weights are used to sample the test case scenarios generated in the orthogonal array which have the same call-mix characteristics. These test case scenarios are used to run tests on the telephone system. These tests are preferably performed using automated test scripts. After the test data is collected, reliability metrics are calculated from the test data.

In the preferred embodiment of the invention, the compound observable state of the electronic device includes a display bit map file or the status of lights or buttons. The compound observable state can be evaluated by the computer in real-time to alert nearby operators of a failure (i.e. a telephone that needs to be rebooted) or malfunction (not rising to the level of a failure). Also, the data related to the compound observable state can be stored in the computer for later review to assist in debugging the telephone's software.

摘要： A MEM inertial sensor (e.g. accelerometer, gyroscope) having integral rotational means for providing static and dynamic bias compensation is disclosed. A bias compensated MEM inertial sensor is described comprising a MEM inertial sense element disposed on a rotatable MEM stage. A MEM actuator drives the rotation of the stage between at least two predetermined rotational positions. Measuring and comparing the output of the MEM inertial sensor in the at least two rotational positions allows for both static and dynamic bias compensation in inertial calculations based on the sensor's output. An inertial measurement unit (IMU) comprising a plurality of independently rotatable MEM inertial sensors and methods for making bias compensated inertial measurements are disclosed.

摘要： A microelectromechanical (MEM) optical switching apparatus is disclosed that is based on an erectable mirror which is formed on a rotatable stage using surface micromachining. An electrostatic actuator is also formed on the substrate to rotate the stage and mirror with a high angular precision. The mirror can be erected manually after fabrication of the device and used to redirect an incident light beam at an arbitrary angel and to maintain this state in the absence of any applied electrical power. A 1×N optical switch can be formed using a single rotatable mirror. In some embodiments of the present invention, a plurality of rotatable mirrors can be configured so that the stages and mirrors rotate in unison when driven by a single micromotor thereby forming a 2×2 optical switch which can be used to switch a pair of incident light beams, or as a building block to form a higher-order optical switch.

摘要： Microfluidic devices are disclosed which can be manufactured using surface-micromachining. These devices utilize an electroosmotic force or an electromagnetic field to generate a flow of a fluid in a microchannel that is lined, at least in part, with silicon nitride. Additional electrodes can be provided within or about the microchannel for separating particular constituents in the fluid during the flow based on charge state or magnetic moment. The fluid can also be pressurized in the channel. The present invention has many different applications including electrokinetic pumping, chemical and biochemical analysis (e.g. based on electrophoresis or chromatography), conducting chemical reactions on a microscopic scale, and forming hydraulic actuators.
