Patent CA-2391486-A1 (CA)
Title: Peak power energy storage device and gravitational wave generator
Inventor: BAKER ROBERT M L JR
IPC: H02K7/18
Filed: 2000-11-17
Abstract: An energy storage device (10) comprising a large scale flywheel supported by a fluid bearing (44, 45). The flywheel has a diameter greater than 100 feet and a concrete, steel-reinforced rim (11) weighing in excess of 1000 metric tons. In off peak periods the apparatus is operated as a motor with energy input causing the rim (11) to rotate up to a predetermined speed and to maintain rotation at that speed in the power take off mode. During peak power time periods, the operation of the electrical circuitry is reversed and the flywheel generates electrical energy which is delivered by the storage device to the power grid. As energy is delivered, the rotational speed of the flywheel diminishes and gravitational waves capable of being shaped and modulated are generated The unique electrical circuit utilizing coils (26) and power transistors (30, 32) under computer software control facilitates operation as a peak power energy storage device or as a gravitational wave generator.

Patent CA-2438857-A1 (CA)
Inventor: JOSHI ABHAY
IPC: H04L12/56
Filed: 2002-02-21
Abstract: The present invention provides a method and apparatus for maximizing throughput of a data call in a wireless communication system in which data is transmitted from a wireless station, such as a mobile station, on multiple assigned channels in accordance with a known transmission standard, such as IS-95B. The multiple assigned channels include a fundamental channel and at least one supplemental channel. Data is formatted into variable rate data frames and transmitted on the fundamental channel and the supplemental channel. A  wireless receiver, such as a base station, receives the multiple assigned channels. The wireless receiver demodulates and decodes data frames associated with each of the multiple assigned channels. The wireless receiver determines a likely initial data rate for each demodulated and decode data frame. The wireless receiver correlates all of the likely data rates, by comparison to one another and to a relevant transmission protocol standard, to determine a maximum likelihood combination of data rates. The maximum likelihood combination of data rates includes a maximum likelihood data rate corresponding to each likely data rate. Decoded data frames are invalidated and erased when the likely data frame rates do not match corresponding maximum likelihood data rates.
