Patent CA-2258009-A1 (CA)
Title: Dsp implementation of a cellular base station receiver
Inventor: SHENOI KISHAN
IPC: H03D3/00
Filed: 1997-06-16
Abstract: Demodulating FM signals using digital signal processing extracts a carrier signal from digitized channel signals, multiplies the digital channel signal with this extracted carrier signal, and further filters out the carrier signal to produce the demodulated signal. The DSP technique first down converts a group of channels to baseband which are then processed through an A/D  converter to produce a digitized composite signal. A bank of bandpass filters, typically based on FFT processors, applied to the composite signal produce (a group of) digitized channel signal(s). The digitized channel signal is then demodulated by recovering a carrier signal by digitally filtering, for example, using a Hilbert bandpass filter, the channel signal and digitally filtering the product of the carrier signal and the channel signal to recover the modulating voice signals.
Patent CA-2261515-A1 (CA)
Inventor: FURBER JOHN
IPC: G01F23/68
Filed: 1999-02-12
Abstract: The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port. The float chamber containing a float operably connected to an alarm. The float, when a chamber is filled with fluid, disables the switch from generating a signal. The float, as the chamber is emptied of liquid, reaches a position and is detected energizing the switch to send a "low or empty product" signal. The apparatus operates by passing liquid through the body. As liquid in the source of liquid is depleted and is no longer available for passage through the body, the body becomes emptied of liquid as the source of pressure removes liquid from the body and particularly from the chamber causing the float to reach a position generating a signal.

Title: Method of pultruding a part from fiber reinforced resin with a wood grain finish
Inventor: DAVIES LAWRENCE W
IPC: B29C70/52
Filed: 1999-02-15
Abstract: A wood grain finish to a pultruded part is obtained by applying to a surface of the part before entering the die a strip carrying male projections shaped in differential depths and spacing across the width of the part to form a simulated wood grain pattern. The strip is then removed after the part is set leaving recesses in the outside surface which provide a simulated wood grain finish which can be differentially stained.

Filed: 1998-07-10
Abstract: In accordance with the present invention, it has been discovered that nuclear receptor proteins isolated from the silk moth bombyx mori (bR) are useful for the regulation of transgene expression. bR is generally thought to be a strong transcriptional regulator within cells of the silk moth. In accordance with the present invention, it has been discovered that bR is also functional in mammalian cells. It has further been discovered that the addition of activation domains to the bR open-reading frame enhances the activity of the ligand modulated regulator to afford high-level transcriptional induction. Further modifications to the bR ligand binding domain result in receptors with unique tranactivational characteristics.

Patent CA-2310818-A1 (CA)
Inventor: LYTINAS MICHAIL
IPC: A61C5/00
Filed: 1999-08-06
Abstract: Disclosed are two methods for coating teeth so as to protect the tooth surfaces from caries and periodontal diseases and optionally paints teeth at a desired color. The anti-caries protection is due to the blocking of the enamel minerals that exit the enamel in order to balance the acidic environment that is created by the bacteria acids. The periodontal diseases protection is due to the low surface tension that is created after the application of specific substances on the enamel, i.e., makes the enamel more slippery. The painting effect comes from the colors that the applied substances have. One embodiment includes three steps: etching of the teeth, application of the protective and painting substance and sealing of the teeth (optional). Another embodiment relates to the implantation of a material in the outer layer of the tooth enamel or dentin or cementum and involves an implantable material, polymer or ceramic, fixed in place by use of a dental laser or a flame. This method also includes three steps: the dental tissue is etched and dried, the material is applied into the tissue, the laser beam or the flame melts the material into the tissue and finally the irradiated spot is air dried.
