Abstract: An occupant weight-based airbag suppression method utilizes adjustable time constant filtering and dynamic threshold adjustment to reliably determine and indicate airbag suppression status. The filter time constant is ordinarily set to a first value that provides relatively fast tracking of the raw occupant weight, but is set to a second value that provides relatively slow tracking of the raw occupant weight when both the raw and filtered occupant weights are within a specified band about the threshold value. The threshold value and band are dynamically adjusted after the suppression status is initially determined so as to effectively increase the separation between the filtered weight and the threshold.

Abstract: A system for testing an integrated circuit device under test (DUT) communicating though synchronous digital signals and through a high speed serialization/de-serialization (serdes) bus includes a serdes interface circuit for communicating with the DUT via the serdes bus and an integrated circuit (IC) tester for communicating with the DUT and with the serdes interface circuit via digital signals. State changes in the digital signals are synchronized to a clock signal within the IC tester. The serdes interface circuit receives instructions from the IC tester via at least one of the digital signals and responds to the instructions by transmitting data to the DUT via the serdes bus using appropriate serdes protocol, by receiving and storing data transmitted by the DUT via the serdes bus, and by thereafter forwarding the stored data to the IC tester via at least one of the digital signals.

Abstract: The device comprises a voltage divider (Rv1, Rv2) to whose two terminals the oscillator signal with a phase position that is mutually opposed is supplied until, in the instance of a switched-on probe heating, the voltage (VRpvs) that is proportional to the probe internal resistance (Rpvs) falls below a predetermined set value (set), whereby, at this point in time, the output signal of the oscillator (SZ) is supplied to both terminals of the voltage divider (Rv1, Rv2) with the same phase position (area 1) thus effecting an amplitude change-over (amplitude amplification).

Abstract: A system and method is provided for remotely and automatically calibrating a mass-flow sensor in a yield monitor of a combine. The invention uses a wireless communication device installed on a combine and a remote wireless communication device installed on a grain carrier or truck carrier. Once an actual weight is obtained, calibration information is sent to the combine to calibrate the mass-flow sensor.

Abstract: The invention concerns a rotational angle measuring arrangement for measuring angle dependent units of an encoding shaft which is journaled in a transducer housing. A stator coupling non-rotationally connects the transducer housing to the housing of a drive system that is to be measured, and the encoding shaft and a drive shaft of the drive system are non-rotatably secured to each other. To provide an improved angle measuring system when the stator coupling is positioned between the transducer housing and the drive housing, to prevent angle measurement errors and to facilitate the mounting of the transducer, at least one locking mechanism is provided. When the transducer, including the stator coupling, is detached from the drive housing, the locking mechanism causes the stator coupling to non-rotatably lock the encoding shaft to the transducer housing, and when the stator coupling is secured to the drive system, the locking mechanism permits the encoder shaft to freely rotate.

Abstract: Methods, systems, and computer program products determine absorption, specific gravity, and/or porosity of construction materials undergoing analysis corresponding to different measurements of material samples divided from a “parent” construction material sample. Dry and wet weights of the samples are obtained under different conditions. In certain embodiments, the material sample is an aggregate that is held in liquid in a volumetric container and the container with the liquid and aggregate is weighed. Another weight of a second sample can be obtained. The second sample is encased in an evacuated vacuum-sealed bag that is opened while immersed in a liquid bath, at which time the weight can be obtained. The weight data can be used to calculate the parameter of interest.

Abstract: A test plug for in-situ testing a glove installed in a glovebox is provided that uses a top plate and a base plate, and a diametrically expandable sealing mechanism fitting between the two plates. The sealing mechanism engages the base plate to diametrically expand when the variable distance between the top plate and the bottom plate is reduced. An inlet valve included on the top plate is used to introducing a pressurized gas to the interior of the glove, and a pressure gauge located on the top plate is used to monitor the interior glove pressure.

Abstract: A catalytic bead sensor or a semiconductor sensor is operated in a manner in which the power requirement is greatly reduced. The reduction in power is accomplished by operating the sensor at a temperature less than the desired operating temperature in the absence of a combustible gas and increasing to the desired operating temperature when the sensor is exposed to a combustible gas.

Abstract: A calibration spring tension adjuster for a seat belt tension sensor has a calibration spring, and a holder. The fixed part and the movable part are adjacent to each other and comprise mutually facing stepped helical faces arranged so that the movable part can be rotated relative to the fixed part causing the steps to slide over each other causing a gap between the stepped faces to increase and compressing the spring. The steps can be arranged so that movement of the movable part in one direction is resisted. The holder is arranged to attach to the fixed part and the spring is held between an abutment face of the holder and a non-stepped face of the movable part.

Abstract: Method for correcting an angle error of an absolute-angle detector that detects the angular position of a first shaft whose rotary movement is linked to a second shaft. The angular position of second shaft is first detected during at least one complete revolution of first shaft; the corresponding angular position of first shaft is derived from this value; the corresponding output value of absolute-angle detector is compared to the corresponding angular position of first shaft, and the difference formed by this comparison is stored. The corresponding output value of absolute-angle detector is then corrected by the stored value.
