Patent CA-2299034-A1 (CA)
Inventor: CARPENTER CHARLOTTE N
IPC: G01R23/16
Filed: 2000-02-18
Abstract: A configurable mufti-rate channelizer (20) is provided to separate an input bandwidth into a plurality of narrowband channels at different data rates, such as 1x, 2x and 4x. The innovative multi-rate channelizer design may contain the same hardware blocks, such as the window presum block 22, the cyclic shift block 24 and the discrete Fourier transform (DFT) block 26 for channelizing both real and complex representations of an input wideband signal into individual channels. However, only some of these hardware blocks may be used while some other hardware blocks may be bypassed depending on the output data rate chosen for an input wideband signal with minimal additional hardware for reconfiguration. For the 1x data rate, all hardware blocks may be used to channelize an input wideband signal into four (4) channels at 1x data rate. For the 2x data rate, most hardware blocks except for a 2-point DFT of the DFT block 26 may be used to channelize an input wideband signal into two (2) channels at 2x data rate. For the 4x data rate, only the window presum block 22 and the 2-point DFT of the DFT  block 26 may be used as first and final stages of accumulation for an integrate and dump operation. This way a single channelizer may be reusable for multiple applications while realizing design gate savings.

Patent CA-2299800-A1 (CA)
Inventor: CHU CHUN LIN
IPC: B05B9/08
Filed: 2000-02-29
Abstract: The invention relates to a liquid spray bottle with manual air pump for spraying an aerosol mist of cooking oil, salad dressing or other liquids. The bottle has a removable base that enables the user to: clean the tubular bottle interior with conventional dishwashing equipment; and to place whole spices and whole garlic cloves within the bottle to infuse flavours into the liquids to be sprayed.  The removable base also serves as a "sacrificial" means to prevent shattering of the internally pressurised bottle when internal pressure is excessively high or when the bottle is accidentally dropped. The removable base with sealing gasket will leak liquid rather than allow internal pressure to exceed the capacity of the bottle. The base will also shatter and leak thereby absorbing impact rather than permitting the bottle to explode. A removable base also eliminates the stability problem caused when the bottom of a blow moulded bottle bulges under pressure since the separate base can be manufactured with any thickness required to maintain a flat configuration independent of the tubular bottle body.

A non-conductive barrier that is operable to move into the gap when the thermal switch moves to an open position, the barrier preventing line voltage surges from arcing between the thermal switch and the voltage sensitive element.

Abstract: A DNA amplification and homogeneous DNA probe assay device is provided which includes a multiplicity of discrete sample cells in a flat "card" format, with each sample cell containing the reagents necessary for both DNA amplification and homogeneous DNA probe assay. The device is particularly suitable for fluorescence polarization DNA probe assays, and is preferably provided with an integral polarizer to avoid the need for polarizing elements in the related measuring apparatus. The size and geometry of the sampe cells allows for a "hot start" of the DNA amplification reaction and thereby avoids mispriming of the amplification reaction.

Title: Method for manufacturing resin-impregnated endless belt structures for papermaking machines and similar industrial applications
Inventor: MCGAHERN DESMOND
IPC: B29D29/00
Filed: 2000-05-11
Abstract: A resin-impregnated endless belt for a long nip press or calender of the shoe type, or for other papermaking and paper-processing applications, has an open base fabric in the form of an endless loop with an inner surface, an outer surface, a machine direction and a cross-machine direction. A coating of a polymeric resin is on the inner surface of the base fabric. The polymeric resin impregnates and renders the base fabric impermeable to liquids, and forms a layer on the inner surface thereof. The coating is smooth and provides the belt with a uniform thickness. The belt is manufactured by mounting the base fabric about a first roll and a second roll, which are separated to place the base fabric under tension in the machine direction. A conveyor belt is placed within the base fabric at a preselected distance from the inner surface thereof. The conveyor belt and base fabric are run at a common speed, and, starting at a lateral edge of the base fabric, polymeric resin is dispensed onto the base fabric over the conveyor belt from a dispenser. The conveyor belt and dispenser are moved transversely across the base fabric as the latter is coated in a spiral fashion.

Inventor: ZHU LILY
IPC: H04B7/005
Filed: 2000-08-17
Abstract: The power level of at least one forward-link signal is determined for a measurement interval, where the measurement interval has a duration smaller than or equal to the time period in which at least one power-indicative signal characteristic can change. For example, a power-indicative signal characteristic used can be the information rate of the signal, which can change once per frame. In this case the measurement interval would be smaller than or equal to a frame. Preferably, the measurement interval is smaller than the time period in which any of the power-indicative signal characteristics can change. The power level of the signal is based on the signal's power-indicative signal characteristics during the measurement interval. In one embodiment of the invention, the signal's power-indicative signal characteristics include the information rate, and the gain of the signal. The power-indicative signal characteristics can also include whether the information contained in a traffic signal is control information or voice and/or data information, whether the signal is setting up a call or is part of an established call, and whether the call is in a soft handoff. Each forward-link signal is a part of a signal set. The signal set can include: all or some of the signals corresponding to a sector of the cell containing the base station; or all or some of the signals amplified by the base station's amplifier. The power level of each signal that is in the signal set is summed to obtain the power level of the signal set.
