  • VIRTUAL BUSINESS CARD AND METHOD FOR SHARING CONTACT INFORMATION ELECTRONICALLY
    Publication number: 20070129959
    Abstract: An apparatus and system for sharing contact information for a contact information database electronically, the system comprising a first and second electronic device, each of device having memory module for storing data, the devices having contact information stored as computer readable data and an integrated wireless radio module, for wirelessly communicating with other devices. The devices establish a wireless connection via the wireless radio modules, send the contact information to via the wireless connection, store the contact information on the memory modules and transfer the contact information to the contact information database.

  • Universal input miniature power supply with a single split transformer primary winding
    Patent number: 6529389
    Abstract: A transformer connected to a power source, which consists of a primary coil, a secondary coil and a magnetic core, the secondary coil being configured to provide a regulated DC output voltage and/or current. The primary coil contains two portions, one portion being used to operate the transformer as a low voltage input converter and both portions being used when the transformer is used as a high voltage input converter.

  • Method and apparatus for asynchronous time measurement
    Patent number: 4908784
    Abstract: The present invention relates to time measurement apparatus and method for measuring, with picosecond precision, intervals between single edged events, where each measured interval comprises the summation of a rough clock count and fine or calibrated vernier counts of measured fractional clock periods before and after each START and STOP event selected from a calibrated vernier memory. The calibrated vernier memory takes the form of a table of linear voltage versus time developed using pseudo-random generated measurement events of random duration and random separation.
