Patent CA-2065810-C (CA)
Title: Content-activation system for an automated mail extraction apparatus
Inventor: HAYDUCHOK GEORGE L
IPC: B43M7/02
Filed: 1992-04-10
Granted: 2004-01-20
Abstract: Envelopes in a bulk-mail processing system are inspected for emptiness, which indicates that all of the contents have been removed. The envelopes are spread apart at an extraction station, for manual or automatic removal of contents. The light transmissivity of the envelope and contents is measured when the envelope is unspread, and then when the envelope is spread. Based on at least the measured transmissivities of the envelope when spread and unspread, a threshold value of transmissivity consistent with the envelope being empty is calculated.

Title: Storage stable powder organosiloxane composition and method for preparing the same
Inventor: BILGRIEN CARL J
IPC: C08J3/12
Filed: 1992-11-09
Granted: 2003-11-25
Abstract: Storage stable and gel-free organosiloxane compositions in the form of flowable powders are prepared by blending a high consistency polydiorganosiloxane into a quantity of fluidized reinforcing filler that is heated to a temperature of from 100 to 200°C. prior to or immediately following introduction of the polydiorganosiloxane. When silica is the reinforcing filler, the filler is typically treated with an anti-creping agent either prior to or during this blending process. The resultant mixture is heated while being subjected to shearing forces that reduce its average particle size to achieve a flowable powder.

Title: Ranging, detection and resolving in a multislope frequency modulated waveform radar system
Inventor: BROVKO OLEG
IPC: G01S13/931
Filed: 1993-02-24
Granted: 1996-08-06
Abstract: A maximum likelihood estimator and range-only-initialization target detection method employed to detect and resolve targets in a multislope linear frequency modulated waveform radar.  The method resolves a large number of target returns without a large amount of signals processing and without creating a significant number of false alarms, or ghosts.  The method simultaneously estimates range and doppler for each target.  The method rejects undesired long-range targets that fold into target regions, and processes target regions of interest around a nearest target to reduce signal processing throughput requirements.  Using a K out of N detection rule, the method detects targets that compete with mainlobe rain clutter, mainlobe ground clutter, and receiver leakage.  The method simultaneously estimates target parameters and optimally resolves any number of targets.  The  method is limited only by the number of frequency modulation ranging slopes, the slope values, and the doppler filter resolution set by the radar waveform design.  The method has the ability to process and detect extended targets. Uses include in automotive cruise control, collision warning systems and airborne radar.

Patent CA-2096991-C (CA)
Inventor: SWAMINATHAN KUMAR
IPC: G10L25/90
Filed: 1993-05-26
Granted: 1997-03-18
Abstract: A high quality low bit rate audio codec having a reproduced voice quality that is comparable to that of a full rate codec compresses audio data sampled at8 Khz e.g., 64 Kbps PCM to 4.2 Kbps or decompresses it back to the original audio or both. The accompanying degradation in voice quality is comparable to the standard 8.0 Kbps voice codes. This is accomplished by using the same parametric model used in traditional CELP coders but determining quantizing encoding and updating these parameters differently. The low bit rate audio decoder is like most CELP decoders except that it operates in two modes depending on the received mode bit. Both pitch prefiltering and global postfiltering are employed for enhancement of the synthesized audio. In addition built-in error detection and error recovery schemes are used that help mitigate the effects of any uncorrectable transmission errors.

Abstract: The coating of an RF active material on a non-RF active substrate material of typical thick-ness for packaging purposes, can generate suffi-cient thermal energy to effect strong bonding of the substrate materials. The RF active material may be deposited on less than the entire inner sur-face area of the substrate material, preferably, at or near the portion of the substrate surface which re-presents the heat seal interface. In this manner of application, additional coating or printing of other substances on the substrate surface can be achieved without hampering the heat sealing pro-cess. Flexible medical containers capable of con-taining a product which is maintained and re-moved under sterile conditions, can be constructed on commercial production machines from these coated non-RF active substrate materials.

Abstract: An osmotic bursting device for dispensing a beneficial agent to an aqueous environment. The device comprises a beneficial agent and osmagent surrounded at least in part by a semipermeable membrane. Alternatively the beneficial agent may also function as the osmagent. The semipermeable membrane is permeable to water and substantially impermeable to the beneficial agent and osmagent. A trigger means is attached to the semipermeable membrane (e.g., joins two capsulehalves). The trigger means is activated by a pH of from 3 to 9 and triggers the eventual, but sudden, delivery of the beneficial agent. These devices enable thePH-triggered release of the beneficial agent core as a bolus by osmotic bursting.]

Abstract: A conductive spring device (46, Fig. 8) is described, which shorts a pair of connector terminals (14, 16) when the connector (12) is not mated to a second connector device (18). The spring device is of the type having a fixed anchor end (50) connected to a first terminal and an opposite contacting end portion (44) which can pivot in a shorting direction (S) to move outwardly (O) and also sidewardly (A) against the second terminal, and which can be forced to pivot in an unshorting direction (U) to move inwardly and sidewardly away from the second terminal. An isolator (92) of insulative material surrounds an inner portion of the second terminal, so when the contacting end portion is in its unshorting position, it cannot move sidewardly against the second terminal. The spring device is formed of a piece of sheet metal with its anchor end (50) having a hole that closely receives the first terminal, the spring device also having a tab (100) which projects inwardly into a slot (102) in the insulative base of the connector to limit pivoting of the spring device about the first terminal.

Granted: 2003-06-10
Abstract: A blood sampling device has a tubular body (1, 2) housing a spring loaded (7) lancet (8) whose needle (17) is initially pro-tected by a cap (20) which projects out from the forward end of the body. A  rocker-like trigger (9) is formed as part of the moulded body (1, 2) and holds the lancet (8) in a retracted position when the lancet is pushed back by the projecting cap (20). The cap can then be removed by a twist and pull action, breaking it free from the lancet body, which is prevented from rotating. Pres-sure on the trigger (9) releases the lancet (8), which is shot forward by the spring (7) for momentary projection of the needle tip (19), and then retracts to bring the needle tip within the body.
