Patent CA-2331800-A1 (CA)
Inventor: GRUBER MORITZ F
IPC: E04F15/02
Filed: 2001-01-22
Abstract: A panel for a portable floor system comprising a rectangular core defining an upper surface and a lower surface extending parallel to the upper surface and lateral side surfaces extending from edges of the upper surface to edges of the lower surface. Frame members are connected to the lateral side surfaces and define outwardly projecting channels. The frame members have opposed spaced parallel horizontal walls defining an upper wall and a lower wall, and further have a transverse connecting end wall for connection to the lateral side surfaces. A laminated graphic layer is integrally joined to the upper surface of the rectangular core and extends over the upper walls of the frame members to conceal the frame members. The channels of the frame members have flanges for releasably securing connecting members for joining a panel to other panels in side-by-side aligned relationship.

Title: Improved radiation synthesizer systems and methods
Inventor: MERENDA JOSEPH T
IPC: H01Q1/27
Filed: 2001-01-24
Abstract: Synthesizer radiating systems provide efficient wideband operation with an antenna, such as a loop, which is small relative to operating wavelength.  Energy dissipation is substantially reduced by cycling energy back and forth between a high-Q radiator and a storage capacitor. Wideband operation is achieved by actively controlling power switch devices. Dissipation is further reduced during high speed switching by use of sequential switching methods to avoid dissipation of energy capacitively stored in switch capacitances, including switch control circuit capacitance. Systems using multi-segment loop antennas are arranged to match antenna input impedance to switching circuit parameters. Personal transmit/receive systems mounted on a jacket or other clothing for field use are enabled.

Title: Adaptive power margin for hard handoffs in code division multiple access based systems
Inventor: CORBETT EDDIE
IPC: H04B7/26
Filed: 1999-07-13
Abstract: A technique for regulating the transmit power level for a mobile station following a hard handoff in a code division multiple access (CDMA) based system is disclosed. In an embodiment of the invention, a profile is develop ed from data associated with transmit power levels from a statistical collectio n of a plurality of hard handoff events. A power margin is derived from the profile such that it may be varied in accordance with high or low load conditions in the system. The power margin is then applied to mobiles performing hard handoffs such that they transmit only at the appropriate pow er level required for a sufficient connection in the cell. The technique provid es an automated and dynamic power margin which is scalale according to the varying loading conditions in the system. The invention reduces the amount o f interference generated by transmitting at unnecessarily high power levels following hard handoffs thereby improving the overall performance and connection quality of the system.

Title: Method, apparatus and computer-readable medium for altering the appearance of an animated object
Inventor: PURDY D GRAY
IPC: G06T13/00
Filed: 1999-08-02
Abstract: A data animation program (11) is provided that alters the appearance of an animated object (39) to reflect a per-centage change in data represented by the animated object. The data is pro-vided to the data animation program by a data source (20) such as a tempera-ture sensor or an Internet web site.   The percentage change in data is converted to a rate of motion for the animated ob-ject. The appearance of the animated object is then altered in accordance with the rate of motion. For example, if the animated object is a propeller, the rate of motion will be expressed in revolu-tions per minute (RPMs) and the pro-peller then spins at the determined rate of motion so as to indicate the percent-age change in data represented by the animated object.
