Title: Method and system for processing first and second digital signal versions of a signal in a diversity receiver
Inventor: ZASTERA BRUCE JOSEPH
IPC: H04B7/08
Filed: 1995-07-20
Granted: 2000-10-24
Abstract: A system for digital selection diversity includes receiving different versions of a signal at different antennas (222, 226) of a receiver (210), and processing the different versions on separate branches each having a digital downconverter (224, 228) and filter (232, 236). The filters are controlled by a diversity switch selector (250) so that one acts to filter (the active branch), and the others decimate their respective input signal versions, based on detected signal quality. The diversity switch selector also controls a demodulator (240) to demodulate the filtered signal. The decimated signals are used to provide both signal quality information, and phase history when a branch becomes active. When the signal quality on an inactive branch is determined to be the greatest, the diversity switch controller controls that branch's filter to switch to a filter mode, and the demodulator to use the last decimated sample for phase history when initially demodulating the signal version coming from the newly active branch.

Title: Long tennis racquet
Inventor: DAVIS STEPHEN J
IPC: A63B60/00
Filed: 1995-08-22
Granted: 2002-01-15
Abstract: A tennis racquet has an overall length greater than 28 inches, preferably between 29 and 32 inches, an egg shape strung surface having a length of at least 14 inches, and a strung surface area greater than 95 square inches. The frame is of widebody construction and formed of a composite material so as to have a minimum weight per unit length. While the overall length is increased, the strung weight of the racquet does not exceed 300 grams, and the mass moment of inertia about the butt does not exceed 56 g-m2. The foregoing racquet produces a number of playing advantages, while maintaining a conventional mass moment of inertia about the handle and thus retain good maneuverability.

Abstract: Disclosed is an improved process for irradiating cell-containing compositions, especially, red cell-containing compositions, wherein vitamin E or a derivative thereof is added to the cell-containing composition prior to, during or after such irradiation. Addition of vitamin E or a derivative thereof is protective of cells in such compositions, but not of virus. Cells irradiated using the inventive process show a reduced leakage of K+ from cells and also a reduced loss of negative charges from the cell membrane compared to cells subjected to the similar process wherein vitamin E or a derivative thereof are not used. In addition, red blood cells sterilized by this process are better preserved during storage and their life-time in the circulation in vivo is greatly enhanced.

Title: Enhanced uplink modulated backscatter system
Inventor: MACLELLAN JOHN AUSTIN
IPC: H04J3/00
Filed: 1996-11-18
Granted: 2004-04-20
Abstract: In accordance with the present invention, a novel Time Division Multiple Access (TDMA) duplex radio communication system comprises an Interrogator which generates a first radio signal by modulating a first information signal onto a radio carrier signal. The Interrogator transmits the first radio signal to at least one remote Tag of the system. The remote Tag receives and processes the received first radio signal. The remote Tag then modulates a second information signal onto a second radio carrier signal to form a second modulated signal. This second modulated signal is then transmitted, in a time-slotted manner, back to the Interrogator. The remote Tag selects, or is instructed, how many times it should repetitively transmit the second modulated signal; and selects, or is instructed, over how many of the time. slots following receipt of the first radio signal the remote Tag should repetitively transmit the second modulated signal. Other embodiments of this invention include the use of Modulated Backscatter to transmit the second modulated signal, and the use of homodyne detection to demodulate the second modulated signal. A      Frequency Division Multiple Access (FDMA) duplex radio communication system embodiment utilizes multiple subcarrier frequencies and another embodiment combines the FDMA and the TDMA methods. A Code Division Multiple Access (CDMA) embodiment utilizes multiple spreading codes; in addition, another embodiment combines the CDMA and the TDMA methods. A novel method for power control of the tag, using modulated backscatter, is also disclosed. Finally, a method for the Interrogator to instruct the Tag to dynamically alter the data rate of the second information signal is also disclosed.
