Abstract: A method and an apparatus for collision detection are proposed, which serve to make faster plausibility checking of a collision signal possible. To that end, the unfiltered sensor signal is used, and this unfiltered sensor signal is compared with a plausibility threshold. Preferably as a function of the comparison of the unfiltered signal with the plausibility threshold, a plausibility flag is set. This plausibility flag can be maintained for a relatively long time by a hold element. As the sensor, an acceleration sensor can advantageously be used.

Abstract: A four point measurement technique for testing programmable impedance drivers such as the BZIO buffers contained in RapidChip® and ASIC devices. Specifically, two test pads are added for taking voltage measurements at additional points. By taking the additional voltage measurements and performing some calculation using Ohm's law, the error components of the testing process are effectively eliminated. The technique is suitable for use at wafer sort where additional device pads can be made available for contact with the automated test equipment (ATE) used in the manufacturing test environment.

Alternatively, the selected module may enable a component type to be input and received on-line and display a component fleet leader.

Abstract: Sensors detect machine parameters such as vibration, turning speed, and temperature, and a local processor performs logic operations based on the parameters and inference rules to produce fault information that is reported to a system processor, which selectively uses the fault information to control the plant machines. The inference rules include rules for determining faults as to balance, alignment, bearing condition, electrical condition, and cavitation. The inference rules are contained in rules code that is separate from the analysis code that performs the logical operations. Thus, the inference rules may be easily changed without changing other code, such as the analysis code.

Abstract: The invention determines the population size and population overlap in data containing records on the unique entities without unique identifiers for the unique entities and having at least one common type of information with a known distribution of finite expectation by decomposing probabilistic calculations. The computer determines population overlap of unique entities between the data sets by subtracting a probabilistic incremental number of unique entities needed for a larger total number of values of the information with the known distribution from the data sets. The invention can also maintain the security of private data by allowing a remote computer where the original data is stored to download diagnostic and aggregation procedures from another computer over a network. The remote computer performs the functions on the data and forwards the results to the estimate processor computer over the network.

In this method, the vector of unknown parameters is segmented into a plurality of groups where each individual group of unknown parameters may be isolated linearly by manipulation of said equations. Multiple concurrent and independent recursive least squares identification of each said group run, treating other unknown parameters appearing in their regression equation as if they were known perfectly, with said values provided by recursive least squares estimation from the other groups, thereby enabling the use of fast, compact, efficient linear algorithms to solve problems that would otherwise require nonlinear solution approaches. This invention is presented with application to identification of mass and thruster properties for a thruster-controlled spacecraft.

Abstract: A method and a battery powered electronic device incorporate use-adaptive fuel gauging. The use-adaptive fuel gauging adapts a fuel gauge algorithm to an average use model for the device. The adaptation accounts for the effects that variations in average use by a user of the device have on a total available energy or charge capacity of a battery. Accordingly, use-adaptivity can improve the fuel gauging accuracy by improving an estimate of the total energy available. The method and device optionally account for different battery chemistries yielding further increases in fuel gauging accuracy compared to conventional fuel gauging approaches.

Abstract: A threshold voltage model with an impurity concentration profile in a channel direction taken into account is provided in the pocket implant MOSFET. With penetration length of the implanted pocket in the channel direction and the maximum impurity concentration of the implant pocket used as physical parameters, the threshold voltage model is obtained by linearly approximating the profile in the channel direction. By analytically solving the model by using a new threshold condition with inhomogeneous profile taken into account, the threshold voltage can be accurately obtained. Based on thus obtained model, the threshold voltage can be predicted and can be used for circuit design.

Abstract: An electrical fuse circuit design for reducing the testing time for a semiconductor device manufactured with redundant eFuse circuitry. A two-to-one multiplexer (MUX) is provided at each eFuse circuit in addition to the fuse latch and pattern latch. Information on which fuse is to be blown is stored in the fuse's pattern latch. The output of the pattern latch is ANDed with a program input to provide a select signal for the MUX. Based on the select signal, the MUX allows the shifted “1” to either go to the next latch in the shift chain or bypass the next latch or latches in the shift chain when the next fuse(s) is not to be blown. Accordingly, the invention enables only those fuse latches associated with fuses that are to be blown to hold up the propagation of the shifted “1” to the next eFuse circuits.

If the value is above a predetermined value, the fault symptom strength is plotted and fitted to a trend line to determine an estimate of when the fault symptom strength will exceed a predetermined value. Output messages are then selected based on the fit.
