Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus and related methods for continuous long-term non-invasive measurement of the pressure of a pulsatile fluid flowing through a flexible tube, particularly human arterial blood flow, is disclosed.          Specifically, the apparatus provides a continuous calibrated pressure measurement by first undertaking a "calibration" phase comprised of determining the pressure at various pre-defined conditions of flow and, in response thereto, ascertaining the values of a plurality of coefficients each of which is associated with a corresponding term in a pre-defined function that characterizes fluid pressure in relation to pulsatile displacement of the wall of the tube; and second, undertaking a "continuous monitoring" phase comprised of determining each subsequently occurring pressure value as the pre-defined function of each corresponding pulsatile wall displacement value, and re-initiating the calibration phase at the expiration of pre-defined time intervals which adaptively change based upon current and prior results.  Methods, which are particularly useful in conjunction with the disclosed apparatus, for ascertaining systolic and diastolic arterial blood pressure values are also disclosed.

Title: Spring coilable top reading rule with improved guide structure for coilable blade
Inventor: CZERWINSKI FRANK G

Granted: 1988-03-15
Abstract: ABSTRACT    A top reading power return rule has a shock-absorbing rib adjacent the spool, to prevent kinking upon retraction of the blade.   The rib is positioned so as to be normally out of contact with  the blade,  but to intercept the blade when engagement of the hook member upon the casing causes it to abruptly stop and snap inwardly.   The rib functions by decreasing the deflection of the taut blade about the small roller closest to the spool; excessive deflection is also avoided by providing a contact surface portion on the rib that is of relatively large area.

Abstract: CHARGE BALANCING DETECTION CIRCUIT          Abstract Prior detection circuits for measuring capacitance differences have commonly included error sources, such as P-N junctions, in the DC signal path. The present invention provides an improved detection circuit for measur-ing the capacitance difference between first (C1) and second (C2) capacitive elements. The detection circuit comprises Q first capacitor (C3) serially connected to the first capacitive element at a first common node (36) to form a first series circuit, and a second capacitor (C4) serially connected to the second capacitive element at a second common node (38) to form a second series circuit. The detection circuit also includes switch means (32) connected betweenthe common nodes and a reference potential, drive means (30) for applying a drive signal across each series circuit, switch activation means (48) and means (34) for measuring the voltage difference between the common nodes. The switch means has a first state in which the common nodes are connected to the reference potential and a second state in which the common nodes are isolated from the reference potential and from one another. The drive signal comprises a series of first voltage transitions (104, 106) operative to vary the total voltage drop across each series circuit. The switch activation means changes the switch means from the first state to the second state at or prior to each first voltagetransition. Therefore after each first voltage transition, the difference between the voltages of the first and second common nodes is a measure of the differencebetween the capacitances of the first and second capacitive elements. A similar technique may be applied to the measurement of the capacitance of a single capacitor.

Abstract: ABSTRACT OF THE DISCLOSURE           A device is disclosed for providing a suckling infant with a liquid diet supplement simultaneously with normal breast feeding.  Improvement in suckling in the child and stimulation of the mother's milk supply are thereby encouraged.  The device includes a container for holding the supplement and at least one tube com-municating with the supplement having an end which is positioned adjacent the user's breast nipple.  A valve mechanism seats on the container mouth, and is comprised of a valve mount on which a flexible valve member is received.  A portion of the valve member covers an aper-ture formed in the valve mount.  The valve member pre-vents liquid from escaping through the aperture, but allows air to enter the container through the aperture when liquid is removed by suckling.  The valve mechanism also permits ready and thorough cleaning of the thin tubing used.  A cleaning solution placed in the con-tainer can be forced through the tubing by squeezing the container, with the valve member preventing the solution from flowing out the aperture.  Two tubes are preferably carried by the valve member and extend through slots formed in the valve mount.  Several inter-changeable valve members are provided which each have a different diameter tubing for adjustment of fluid flow.        A neck cord for suspending the device in position on the chest is also disclosed, along with an attachment ring for the valve mechanism which has a plurality of notches into which the tubing can be wedged to pinch it closed when not in use.

Abstract: ACTIVE IMPEDANCE LINE FEED CIRCUIT Abstract of the Disclosure A typical active impedance line feed circuit includes tip and ring amplifiers being controlled in response to signals at tip and ring voltage taps by a control circuit to exhibit a.c. impedance and d.c. resistance characteristics for the purpose of supplying energizing current via tip and ring terminals for tip and ring leads of a two wire communication line.  In one example of the active impedance line feed circuit, improved operational tolerance of longitudinal interference and of a ground fault condition is provided by a d.c. amplifier being responsive to voltages at the tip and ring terminals.  The circuit is characterized in that an inverting input of the d.c. amplifier is connected via resistors to the tip and ring voltage taps.  In operation, the d.c. amplifier provides complete cancellation of all common mode signals at the tip and ring voltage taps and a compensation circuit is also connected between the tip and ring voltage taps and is responsive to the output of the control circuit for compensating for non-symmetrical current, the non-symmetrical current being introduced between the tip and ring voltage taps by normal operation of the control circuit, thereby, a threshold of ground fault current limiting action is substantially constant under all operating conditions.  The d.c. amplifier is conveniently manufacturable in integrated circuit technology along with the remaining amplifiers in the active impedance line feed circuit.                             - i -
