  • Patent number: 6613473
    Abstract: A higher amp-hour capacity battery is formed in a conventional battery package by arranging cylindrical cells in a bundled configuration. A bundle of cylindrical cells, whether nonrechargeable or rechargeable may be less expensive to produce and may offer more desirable charge and discharge characteristics than other arrangements and cell geometries, even though some space in a resulting package is not occupied by cells. A rectangular 9-volt type battery may include seven cells wired in series and bundled horizontally or vertically inside the rectangular case.

  • Patent number: 5675344
    Abstract: The method includes receiving (404) by a first base station (212) a signal (215) transmitted from the mobile station (216); demodulating (406) the signal by the first base station (212) to form a demodulated signal; remodulating (408) at least a portion of the demodulated signal to form a reference signal; receiving (412) by the first base station (212) and a second base station (210, 214) a retransmitted signal (217); comparing (414, 16), by the first base station (212), the retransmitted signal (217) with the reference signal to determine a first delay; comparing (414, 416), by the second base station (210, 214), the retransmitted second signal (217) with the reference signal to determine a second delay; and based on the first and second delays, determining (420) a location of the mobile station (216).
