  • Patent number: 6088220
    Abstract: Prior miniaturzed palm-top computers have reduced-size keyboards which are not useful for standard typing. The present invention provides a folding pocket-sized computer, comprising up to a 12" screen, a central processing unit, data storage and input means and a full size computer keyboard. It does this by having the keyboard divided into two halves hingedly connected along a fold line, whereby one of the keys is split along the fold line to permit folding of the keyboard, and by folding the screen and abutting the sections of the screen with no intervening frames.

  • Patent number: 6086615
    Abstract: A pylon includes a first end portion connected to a patient's leg stump and a second end portion connected to a prosthetic foot. The second end portion includes a piston, and the first end portion includes a piston chamber receiving the piston. The second end portion is thus rotatable and axially movable relative to the first end portion about and along a longitudinal axis of the pylon, respectively. The piston chamber encloses a compressible volume of fluid through which substantially all of the patient's weight applied through the patient's leg stump is supported. The compressible volume of fluid is sealed so that it can be pressurized. Also, a torsional spring couples the piston and piston chamber and resists relative rotation between the piston and piston chamber without supporting any substantial portion of the patient's weight applied through the patient's leg stump to the piston. The present invention thus advantageously provides a pylon which is more cushioned and resilient than conventional pylons.

  • Patent number: 6081660
    Abstract: A method of forming a cohort for use in identification of an individual by comparing a model of characteristics of the individual, such as a model of utterances, with models of the cohort including a model for the client in respect of whom it is desired to test whether the individual is identifiable. Models related to the population excluding the client are tested to determine whether they meet an acceptance threshold test as to identify with a model for the client. Then, from each meeting the threshold test, it is determined whether those models are distributed so as to present at least a substantial probability that models for nonmembers of the population spaced from the client model in all directions will each be closer to a member of the cohort, excluding the client, than to the client. If that probability is less than a predetermined value, a selection is made from the population of another cohort member which will reduce that probability.

  • Patent number: 6075718
    Abstract: The method comprises the steps of detecting the trailing edge of an initialization signal, and generating a read bias signal and a read activation signal for the cell, when the trailing edge of the initialization signal is detected. The signals of read bias and read activation have a ramp-like leading edge and both signals are disabled when reading of the cell is completed. Thereby, phenomena of soft-writing of the cell are avoided, and risks of erroneous readings are reduced.

  • Patent number: 6069837
    Abstract: A row decoding circuit for an electronic memory cell device, particularly in low supply voltage applications, is described. The row decoding circuit is adapted to boost, through at least one boost capacitor, a read voltage to be applied to a memory column containing a memory cell to be read. The circuit is powered between a first supply voltage reference and a second ground potential reference, and comprises a hierarchic structure of cascade connected inverters and a circuit means of progressively raising the read voltage level dynamically. First means are provided for raising the read voltage level to a value equal to the supply voltage plus a threshold voltage, and second means are provided for raising the read voltage level to a value equal to the supply voltage plus twice said threshold voltage.

  • Patent number: 6058450
    Abstract: A method interfaces a plurality of bus requesters with a computer bus. The method apportions the bus bandwidth among the bus requesters by assigning to each bus requester a bus bandwidth portion that is based on the bandwidth of the bus requester. The method identifies a requester bandwidth for each of the bus requesters and sums the requester bandwidths to obtain a total bandwidth. The method determines, for each of the bus requesters, a weighting value representing the ratio of the bus requester bandwidth to the total bandwidth. The method apportions the bus bandwidth among the bus requesters by assigning each bus requester a bus bandwidth portion that reflects the weighting value of the bus requester. Apportioning the bus bandwidth based on the weighting values causes the requester bandwidth of each bus requester to be reduced by the same percentage when the bus saturates.

  • Patent number: 6055654
    Abstract: A test circuit for a memory device having a pair of arrays each of which includes a plurality of memory cells arranged in rows and columns, and a pair of complimentary digit lines being provided for each column of each array. The digit lines are selectively coupled to a pair of I/O lines for each array which are, in turn, coupled to a pair of complimentary data lines. The data lines are coupled to respective inputs of a sense amplifier, one of which is provided for each array. A multiplexer connects the pair of I/O lines for either one of the arrays to the data lines in a normal operating mode. Thus, in the normal operating mode, data is selectively coupled to the inputs of the sense amplifier from the complimentary digit lines for an addressed column. In a test mode, the multiplexer connects an I/O line for one array to one of the data lines and an I/O line for the other array to the other data line.

  • Patent number: 6052798
    Abstract: A computer system includes a memory requester that interfaces with a memory module that includes memory portions. An error map that identifies the defective memory portions of the memory module is created and stored in the computer system. Using the error map, a remapping table that maps each of the defective memory portions to a non-defective memory portion in the memory module is created and then stored. In response to receiving from the memory requester a request for access to a requested memory portion of the memory module, a determination is made from the error map whether the requested memory portion is one of the defective memory portions. If the error map indicates that the requested memory portion is one of the defective memory portions, then a determination is made from the remapping table the non-defective memory portion to which the requested memory portion is mapped.
