Patent CA-2262895-A1 (CA)
Title: Intrusion detection system using quiet signal band detection
Inventor: GAGNON ANDRE
IPC: G08B13/24
Filed: 1998-06-05
Abstract: In an intrusion detec-tion system of the kind which comprises a "leaky cable" or open transmission line and is used to determine the pres-ence of objects, things or peo-ple moving in the vicinity of the leaky cable, a transmit-ting antenna (10) and a re-ceiving antenna (18), one of which is an open transmis-sion line/leaky cable, are con-nected to a transmitter unit (14) and a receiver unit (18), respectively. A control unit (26) controls both the trans-mitter unit (14) and the re-ceiver unit (18), and causes the receiver unit (18) to scan a preselected radio band, with the transmitter unit (14) not transmitting, to detect one or more relatively quiet portions of the band in which instant received signal levels are lower than a predetermined threshold. The control unit (26) selects a plurality of disparate frequencies in such one or more relatively quiet portions and subsequently causes the transmitter unit (14) to transmit signals by way of the transmitting antenna (10) at the disparate frequencies. The receiver unit (18) receives signals corresponding to the transmitted signals and the control unit (26) detects perturbations in the received signals caused by an intruder in the vicinity of the leaky cable to determine the presence of the intruder. The disparate frequencies may have a bandwidth equal to at least 5 per cent and preferably about 10 per cent of their mean frequency. Operation in the quiet bands allows frequency diversity to be employed, reducing the effects of standing waves and allowing the leaky cable to be deployed without a surrounding electrically-lossy medium, for example above ground, while providing uniform detection sensitivity.

Title: Combined subtractive interference cancellation and space diversity signal processing in a cellular cdma communications system
Inventor: DENT PAUL W
IPC: H04B7/26
Filed: 1997-08-12
Abstract: A communications system is disclosed comprising a plurality of mobile stations and an improved base station for receiving signals from said mobile stations and decoding information-bearing signals transmitted therefrom. An antenna comprising antenna elements disposed around a support structure receives signals transmitted from the plurality of mobile stations and generates output signals from each antenna element. Convertors amplify, filter and convert signals from each of the antenna elements into a corresponding number of converted signals for processing. Storage devices temporarily store a number of samples of the converted signals. Processors iteratively process and reprocess the stored samples successively to decode the information from each of the mobile stations in turn. The processing provided by the processors identifies from the stored samples an information symbol transmitted by one of the mobile stations thereby decoding the information-bearing signal, and subtracts values dependent on the identified information symbol from the stored samples thereby reducing interference between the just-decoded signal and the signal to be decoded at a subsequent iteration.

Patent CA-2271410-A1 (CA)
Title: Speech coding apparatus and speech decoding apparatus
Inventor: OZAWA KAZUNORI
IPC: G10L19/10
Filed: 1999-05-10
Abstract: A speech coding apparatus includes a spectrum parameter calculation section, an adaptive codebook section, a sound source quantization section, a discrimination section, and a multiplexer section. The spectrum parameter calculation section receives a speech signal and quantizes a spectrum parameter. The adaptive codebook section obtains a delay and a gain from a past quantized sound source signal using an adaptive codebook, and obtains a residue by predicting a speech signal. The sound source quantization section quantizes a sound source signal using the spectrum parameter. The discrimination section discriminates the mode. The sound source quantization section has a codebook for representing a sound source signal by a combination of non-zero pulses and collectively quantizing amplitudes or polarities of the pulses in a predetermined mode, and searches combinations of code vectors and shift amounts used to shift the positions of the pulses to output a combination of a code vector and shift amount which minimizes distortion relative to input speech. The multiplexer section outputs a combination of outputs from the spectrum parameter calculation section, the adaptive codebook section, and the sound source quantization section.

Title: Disposable mandibular advancement appliance
Inventor: FRANTZ MICHAEL D
IPC: A61F5/56
Filed: 1997-12-15
Abstract: A mandibular advancement, or positioning, device for short-term or one-time use is described. The appliance has an upper tray and a lower tray holding impression material, into which the patient bites. The impression material, and optional adhesive, serve as a way to secure the trays to the patient's upper and lower teeth, and, therefore, to the patient's maxilla and mandible. Preferably, the front portions of the trays are bendable or flexible, for allowing the use of just a few sizes of trays for all patients. A connector is attached to a rear area of the lower tray and adjustably connects to the upper tray at or near the center of the upper tray front area, so that the connector easily may be manually pulled forward and temporarily locked in place to advance the mandible. The device is particularly useful for short-term use in applications which do not require long-teem comfort and durability, such as sleep-lab testing of the usefulness of mandibular advancement in treating a particular patient, or as a step in surgical anesthesia to enlarge a patient's pharyngeal airway space.
