Patent CA-2039096-A1 (CA)
Title: Thermostat with means for disabling pid control
Inventor: BIRD DOUGLAS D
IPC: G05B5/01
Filed: 1991-03-26
Abstract: ABSTRACT        A thermostat is disclosed which includes a Proportional-Integral-Derivative (PID) controller and a means for disabling the PID controller for selected periods.  The PID controller is disabled during a temperature recovery period, which can be triggered by the occurrence of one or more of many preselected events.  The PID controller is re-enabled when the thermostat setpoint less a void offset temperature is reached.  To reduce error in future temperature recovery periods, the void offset temperature is adjusted after a temperature recovery by adding the amount of error to the void offset temperature to create a new void offset temperature for use in a next temperature recovery period.

Title: System for distinguishing or counting spoken itemized expressions
Inventor: THEIS PETER F
IPC: G10L15/04
Filed: 1991-08-29
Abstract: ABSTRACT OF THE DISCLOSURE A speech categorization system includes first and second timers which generate first and second measured durations indicative of duration of selected higher and lower amplitude segments included in a voice message.  A higher amplitude segment is classified in a first category when the first and second measured durations corresponding to the higher amplitude segment and an adjacent lower amplitude segment satisfy a classification test, and a counter counts the number of the higher amplitude segments classified in the first category.  To detect spoken itemized words such as numbers or letters, the classification test can include the requirement that the lower amplitude segment be relatively short as compared to the preceding higher amplitude segment.

Inventor: HATANAKA KATSUNORI
IPC: G01Q30/04
Filed: 1992-04-21
Abstract: In order to effect the reading-out of a signal from a recording medium at a high speed and without the collision of a probe electrode, the control of the spacing between the probe electrode and the signal recording layer of the recording medium is effected by sampling a tunnel current detected by the probe electrode at the timing of a reproduction clock, and reproduction is effected with this sampled value as a reference. Also, in order to effect information recording with good reproducibility and at high density, the control variable of a servo control circuit for controlling the spacing between the probe electrode and the recording layer is changed over during the periods before and after a writing pulse is applied to the probe electrode. Also, in order to effect re-recording reliably, the prior recorded state at the re-writing position is detected, and from the result of this detection, an optimal servo control variable, the waveform of a pulse voltage applied, etc. are set. <IMAGE>

Filed: 1992-06-03
Abstract: ABSTRACT         An attachment for securing a leg to an article of furniture, such as a table, eliminates the use of the costly sub-frame that would normally be required.  The attachment utilizes a rigid large flat steel plate that is connected to the upper end of the leg by machine screws passing through holes in the plate and spaced axially extending bores in the table leg, these bores leading to a transverse bore in which is positioned a cylindrical dowel pin.  The ends of the machine screws are threaded into the dowel pin and the screws can then be tightened to clamp the plate to the leg.  The plate is of very much greater area than the leg and has holes around its perimeter through which wood screws can be passed to attach the plate to the underside of a table or the like.

Abstract: ABSTRACT OF THE DISCLOSURE    An infusion device which permits transcutaneous access to an implanted catheter for use in introducing an external filament such as a optical fiber, external catheter, guide wire or rigid needle.  In accordance with this invention the device includes a valve assembly including a first valve element defining an aperture with a sealing member which is normally to engage and sea} against the aperture.  The sealing element is made from a hard material such as a metal.  Upon introduction of a rigid external  introducer such as a needle,  the needle  directly contacts the sealing member plug unsealing it from the valve element aperture which then closes against the external element. The device enables repeated access using a sharp introduced element such as a needle without it contacting soft sealing elements which could be degraded by such repeated access.
