  • Patent number: 9910998
    Abstract: A method, system, mediation server, client, and computer program for deleting a copied file in which a master file is duplicated while maintaining a certain level of security. A mediation server receives and stores a copied file in which a master file stored in a server is duplicated, generates private-key information and public-key information, and transmits the generated public-key information and the copied file to a client. The client receives and stores the copied file and the public-key information. In a case where the copied file is updated, the client encrypts difference information on the difference arising in the updating using the public-key information and transmits the difference information to the mediation server. The client determines whether the condition for being secure is satisfied when a process for updating the copied file becomes possible. When determining that the condition is not satisfied, the client deletes the copied file.

  • Publication number: 20120051492
    Abstract: Anti-lock and intelligent braking systems have become ubiquitous in modern vehicles, which employ wheel speed sensors or WSSs. These WSSs generally uses current-domain signals (transmitted through power wires) to reduce the size of the vehicle's wiring harness, but because a vehicle is an inherently noisy environment, mixed signal circuit or MSC (used to decode these signals for a microcontroller) should be able to filter out or compensate for noise. However, traditional MSCs have been plagued with problems, partly due to errors in time base measurement due to noise (as well as other factors). Here, an MSC is provided that accurately calculates a wheel speed pulse width (which is used for time base measurements) by observing the wheel speed pulse as it passes through several thresholds.

  • Publication number: 20090323888
    Abstract: A step count measuring system includes a pedometer and a step count managing apparatus which are able to communicate, with each other. In the pedometer, a step count value sequentially detected for each unit of time is stored, and a time counted in the pedometer is stored as first time data by being brought into associated with each of the step count values. When a battery is replaced in the pedometer, a reset is executed to start initialization processing, and the time stored as first time data is stored as second time data which can be discriminated from the first time data. A recording time of each of the step count values being associated with the first time data before the initialization processing is set on the basis of the time counted by the step count managing apparatus, and a recording time of each of the step count values being associated with the second time data after the initialization processing is set on the basis of the second time data.

  • Publication number: 20080258825
    Abstract: Random number generators are used for entertainment in gambling, lotteries and video gaming devices. True Random Number Generators, as are now currently defined, must be actuated by a physical noise source, typically based on the uncertainty of the phase differences of a stable and an unstable autonomous oscillator. In this invention an autonomous random frequency modulated oscillator driven by a self contained pseudo-random number generator outputs three loosely correlated random binary streams. Included in the invention is a hardware method for proving wandering phase differences and also the existence of a colored random distribution of concatenated nibbles.

  • Publication number: 20080159467
    Abstract: A method for determining the rotation speed of a rotating shaft that has associated with it a means that has markings which produce an electrical signal upon being carried past a sensor element of a sensor, the sensor encompassing an evaluation device that counts the markings carried past the sensor element within a gate time and transfers them to a control unit as a numerical value. The gate time is derived from a time increment, and a pulse having an actual time duration derived from the time increment is transferred to the control unit and is compared by the control unit with a target time duration, the numerical value being corrected using a correction value that is ascertained from a comparison of the actual time duration with the target time duration.

  • Patent number: 7113886
    Abstract: A circuit and related method for distributing events in an event stream (i.e., an electronic signal having a plurality of rising edge transitions and falling edge transitions). The circuit distributes the events in a primary event stream across multiple secondary event streams in such a way that the event rate in each of the secondary event streams is lower than the event rate in the primary event stream, but the relative timing of the events in the primary event stream is maintained in each of the secondary event streams. The secondary event streams can then be provided to respective timestamp circuits, which record the times at which events occur in the secondary event streams. Since the relative timing of the events in the primary event stream is maintained in each of the secondary event streams, the multiple timestamp circuits collectively record the times at which events occur in the primary event stream. The circuit and related method can be used when debugging/testing semiconductor devices.
