    摘要: An identification tag reader reads identification tags on vehicles of a train consist. Identification tag identifiers are used to retrieve weights and lengths of the vehicles, and the weight and length information is used by an onboard train control system either to verify weight and length information already stored in the system or input the information initially, in either case for use in controlling the train such as in the calculation of braking curves. In another embodiment, an identification tag reader is paired with a sensor capable of detecting a condition on a train vehicle requiring maintenance, and the condition and an identification tag identifier are transmitted to maintenance personnel. The identification tag is preferably an AEI tag.

    摘要: A method for statistically distinguishing between two or more populations, such as between samples containing background and threat particles, is disclosed. According to one embodiment, the method for statistically distinguishing is a method for processing a signal in a particle detection system. The method may include characterizing each particle detected by a signal vector. The method may further include calculating a weight of each particle detected using a weighting function of the signal vectors. The weighting function may be a functional of a threat particle probability distribution and a background particle probability distribution. The method may also include summing a total weight of all particles tested and generating an alarm signal if the total weight exceeds an alarm level.

    摘要: An apparatus and method is provided that reduces the propagation delay in a conductor carrying an electrical signal from a first area of a circuit to a second area of the circuit. The conductor is fabricated to include a first conductor extending from the first area to the second area. The conductor also includes a second conductor extending substantially parallel and along the first conductor and electrically connected to the first conductor. A third and additional conductors may also be used which extend substantially parallel and along the first conductor and are electrically connected to the first conductor. The additional second conductor (and any additional conductors) reduces the capacitance of the conductor thereby reducing the propagation delay in the conductor (increasing the speed of the signal). The additional conductor(s) effectively “shield” the first conductor from some capacitance that the first conductor would normally “see” without the use of such additional conductors.

    摘要: A scanning fingerprint detection system that includes an array of capacitive sensing elements. The array has a first dimension greater than the width of a fingerprint and a second dimension less than the length of a fingerprint. Each of the capacitive sensing elements has a size less than the width of a fingerprint ridge. Circuitry is provided for scanning the array to capture an image of a portion of fingerprint and for assembling the captured images into a fingerprint image as a fingerprint is moved over the array.

    摘要: A redundant circuit and method for a semiconductor memory device is disclosed. The redundant circuit includes a programmable circuit for selectively generating at least one first address corresponding to a defective memory row or column line, and shifter circuitry for remapping second addresses which are greater than the first address to row/column lines. For each second address which is greater than the first address, the shifter circuitry remaps the second address to a row/column line which was initially mapped to an immediately higher address relative to the second address. The programmable circuit is capable of generating a plurality of first addresses corresponding to a plurality of defective memory row or column lines.

    摘要: A method and apparatus for reducing the time for determining a memory refresh frequency for a dynamic random access memory. The method includes disabling the bootstrap circuitry associated with a word line when writing data into a memory cell during a test operation. For instances in which data representing a high logic level is written into the memory cell, the resulting charge that is stored is less than the stored charge under normal operation of the dynamic memory. Consequently, the decay time for the stored charge is shortened, thereby shortening the time for testing the refresh frequency of the memory cell. Testing time for the dynamic memory is thus reduced.
