Patent CA-2188926-A1 (CA)
Title: Implantable Capacitive Absolute Pressure and Temperature Sensor
Inventor: HALPERIN LOUIS E
IPC: G01L9/12
Filed: 1996-01-24
Abstract: An endocardial lead (12) for implantation in a right heart chamber (RV) for responding to blood pressure and temperature and providing modulated pressure and temperature related signals to an implanted or external hemodynamic monitor (100) and/or cardiac pacemaker or pacemacker/cardioverter/defibrilator.  The lead (12) has a sensor module (20) formed in its distal end and is coupled to a monitor (100) that powers a sensor circuit in the sensor module. The sensor module is formed with a pickoff capacitor (Cp) that changes capacitance with pressure changes and a reference capacitor (Cp) that is relatively insensitive to pressure changes. The sensor circuit provides charge current that changes with temperature variation at the implant site, alternately charges and discharges the two capacitors, and provides timing pulses having distinguishable parameters at the end of each charge cycle that are transmitted to a demodulator (150). The demodulator (150) detects and synchronizes the timing pulses and derives pressure and temperature analog voltage values representative of the intervals between the timing pulses which are digitized and stored in the monitor. The monitor may also be coupled with other sensors (106, 152) for measuring and storing related patient body parameters, e.g. blood gas, ECG, and patient activity.

Patent CA-2190688-A1 (CA)
Inventor: NUBER RAY
IPC: H04N19/895
Filed: 1996-11-19
Abstract: Audio data is processed from a packetized data stream carrying digital television information in a succession of fixed length transport packets. Some of the packets contain a presentation time stamp (PTS) indicative of a time for commencing the output of associated audio data. After the audio data stream has been acquired, the detected audio packets are monitored to locate subsequent PTS's for adjusting the timing at which audio data is output, thereby providing proper lip synchronization with associated video. Errors in the audio data are processed in a manner which attempts to maintain synchronization of the audio data stream while masking the errors. In the event that the synchronization condition cannot be maintained, for example in the presence of errors over more than one audio frame, the audio data stream is reacquired while the audio output is concealed. An error condition is signaled to the audio decoder by altering the audio synchronization word associated with the audio frame in which the error has occurred.

Title: Balloon expandable stent-graft delivery system
Inventor: GATERUD MARK T
IPC: A61F2/91
Filed: 1995-10-20
Abstract: A stent-graft delivery system (10) which includes a catheter (12), an expandable balloon (18) having non-tapered ends positioned near the distal end of the catheter (12), a stent (20) circumferentially positioned around a center of the balloon, and a graft (22) circumferentially positioned around the stent (20). The balloon configuration comprising non-tapered ends may be achieved by 1) preforming the balloon to the desired geometry which comprises substantially non-tapered ends; 2) positioning a non-compliant sheath (24) over each of the ends of an existing balloon (18) having tapered ends, or 3) invertedly attaching the first (42) and second (54) ends of a compliant tubular member to the catheter to form the desired balloon (18) configuration.  The desired balloon configuration is a balloon geometry which uniformly conforms to the geometry of the stent-graft assembly. A method for introducing the stent-graft delivery system into a blood vessel are also disclosed. The method includes inserting the stent-graft delivery system into the blood vessel, guiding the stent-graft assembly to the desired site, inflating the balloon of the balloon catheter, deflating the balloon, and withdrawing the catheter and expandable balloon. The stent-graft delivery systems (10) are also suitable for introducing and delivering stents (20) without grafts (22).
Patent CA-2204089-A1 (CA)
Title: Digital delay locked loop
Inventor: MILLAR BRUCE
IPC: G11C7/22
Filed: 1997-04-30
Abstract: An improved edge-triggered fully digital delay locked loop (DLL), which maintains reliable synchronization from startup and in spite of system clock jitter is described.  An internal clock signal is synchronized with a reference clock signal by propagating the reference clock signal through a variable digital delay path. A wide phase detection region surrounds a selected rising edge of the internal clock signal.  The DLL loop is open as long as the internal clock signal and a target edge of the reference clock signal are not simultaneously within the phase detection region.  To achieve a DLL locked condition, the variable delay is increased from a minimum setting until the edge of the phase detection region is shifted in time just past the target edge of the reference clock. Once the DLL loop has been closed, a clock jitter filter is enabled to reject reference clock jitter effects on the DLL locked condition.  A digital phase detector controls the delay line propagation delay to establish synchronization between the internal clock and the reference clock. Unused delay elements within the variable delay path are deactivated to save power.
Patent CA-2205545-A1 (CA)
Title: Method and apparatus for detecting and identifying microbial colonies
Inventor: MORGAN SCOTT D
IPC: C12M1/34
Filed: 1995-09-20
Abstract: A method and system for detecting and identifying microbial colonies in an inoculated growth medium first acquires a first image of the inoculated growth medium (100). After a selected incubation time interval (110), a second image of the growth medium is acquired (100). A difference image is produced by taking the difference between corresponding pixels in the first and second images (112). Potential colonies are identified within the difference image by locating peak pixels having local maximum pixel intensities within the difference image and having decreasing gradients in a predetermined number of directions (118). The potential colonies are validated as actual colonies by eliminating those potential colonies that are noise spikes or noise around previously validated colonies (120).
