Title: Automatic blood pressure monitor with a dual-speed control circuit for the dc inflation pump motor
Inventor: NEWELL SCOTT
IPC: A61B5/0235
Filed: 1995-05-24
Abstract: An automatic blood pressure monitor has a dual-speed control circuit which is used to control the speed of a DC motor that powers the inflation cuff.  The control circuit limits the motor current, permitting operation from a limited power source (such as a battery).  The control circuit also includes a means for electrically braking the motor; the motor is braked after a time delay which commences after motor power is cut off.
Patent CA-2151330-A1 (CA)
Inventor: ISO KEN-ICHI
IPC: G10L15/02
Filed: 1995-06-08
Abstract: A speech recognizer performs recognition of input speech by analyzing the input speech at a predetermined time interval, extracting feature vectors and calculating a likelihood value of a reference pattern model of each category to be recognized. A first probability calculation means calculates a probability that a first hidden Markov model having an internal state number as an output symbol for each of the categories to be recognized outputs an internal state number. A second probability calculation means calculates a probability that a second hidden Markov model having transition probabilities of internal state number and feature vector output probability distribution for each of the respective internal state numbers, outputs a feature vector. A likelihood value calculation means calculates a likelihood value of a reference pattern model of the category to be recognized by using outputs of the first and second probability calculation means.

Title: Oscillometric blood pressure monitor employing deflation periods of alternating durations
Inventor: BOOTH JOHN
IPC: A61B5/022
Filed: 1995-09-28
Abstract: An automated sphygmomanometer in which the timeout duration of respective deflation periods during which oscillatory complexes may be detected is alternated so that the monitor cannot synchronize with the heart rate for more than one deflation step.  The timeout durations at each deflation step are alternated to have long-short-long-short durations so that the overall duration of the measurement cycle is preferably about the same as in conventional monitors in which the timeout periods all have the same duration.  Once the oscillatory complexes are detected, the timeout is typically not needed and the processing proceeds to the next deflation step in a conventional manner.

Title: Method for improving wear resistance of polymeric bioimplantable components
Inventor: HAMILTON JOHN V
IPC: B65B55/16
Filed: 1996-04-02
Abstract: Wear resistance and oxidation resistance of bioimplantable polymeric parts is improved by packaging the parts within flexible, gas impermeable containers while subjecting the containers and the parts to a relatively high vacuum force. The containers are heat sealed while subjected to the vacuum force such that, upon sealing, hydrostatic pressure is exerted on the part. Following sealing of the packages,-the packages and their contents are irradiated to an extent sufficient to sterilize the parts and to promote crosslinking within the part. Alternatively, the same property enhancements can be imparted to polymeric parts by packaging the part within rigid or flexible containers, minimizing the oxygen content within the containers, pressurizing the containers with an inert gas, or with a mixture of hydrogen and an inert gas, to greater than 1.5 atmospheres, and irradiating the part and the container.

Patent CA-2178968-A1 (CA)
Title: Leakproof shower curtain
Inventor: MOSESON YEHUDA
IPC: A47K3/38
Filed: 1996-06-14
Abstract: This invention creates a system with the capability and methodology forsealing the junctions between shower curtains and bathtub, or shower stall, or whirlpool surfaces, thereby preventing water leakage into areas surrounding bathtubs or shower stalls or whirpools.   The common problem of water leakage into areas exerior to the bathtub, or shower stall, or whirlpool, is caused by the lack of an adequate seal between the shower curtain and the surrounding surface.   A solution to this problem was developed using a system to adequately seal the junctions between shower curtains and surrounding surfaces. This is made possible by the application of one velcro strip along the leading edge of either or both sides of the shower curtain annexed to the auxiliary portion of the velcro strip which adheres to the primary edge of the contiguous wall of the shower stall, bathtub, or whirlpool by means of either gluing, sewing, heat-sealing or otherwise.   A shower curtain may ordinarily be made of assorted materials, such as cloth, nylon, or polyester, (to name a few), all of which will now, by utilization of this invention, effectively contain the water.
