Patent CA-2141154-A1 (CA)
Title: Device for Measuring Rotary Speed of a Rotating Member
Inventor: TERAMAE KATSUHIRO
IPC: G01P3/48
Filed: 1995-01-26
Abstract: A rotary speed measurement device comprises an oscillator including a resonant circuit with a coil which conducts a resonant current to develop a magnetic field therearound. A wheel is connected to rotate together with a rotating member and is provided along circumference with alternately arranged first and second marks which causes different magnetic effect on the magnetic filed. The coil is disposed adjacent the wheel so as to sense the magnetic effect and provide a corresponding voltage Vs. An analyzer is provided to give a parameter Vsub based upon voltage Vs and to compare the parameter with a predetermined threshold V TH to give a pulse when the parameter exceeds the threshold as indicative of that the wheel rotates by an increment corresponding to an angular distance between the first mark and the adjacent second mark. The pulse is counted by a counter within a unit time to obtain a rotary speed of the wheel. The device is characterized to include a reference circuit connected in circuit with the resonant circuit to provide a reference voltage Vr which is in phase with voltage Vs and varies at a different rate from voltage Vs in response to the inductance change in the coil, and to include a differential low-pass filter which is connected to receive voltage Vs and reference voltage Vr for providing a difference therebetween as the parameter Vsub to be compared at the analyzer with the threshold V TH. Thus, voltage difference between Vs and Vr can represent the parameter of which amplitude is kept within a limited range irrespective of the distance between the coil and the wheel, whereby realizing successful rotary speed measurement without necessitating to care the relative position of the rotor to the wheel, and extending the measurable distance between the coil and the wheel.

Title: Finger cot oximetric probe
Inventor: BRANIGAN BRENDAN
IPC: A61B5/024
Filed: 1994-07-13
Abstract: An oximetric sensor probe (21) is movably coupled to a patient's finger to facilitate transillumination and detection of optical energy through a portion of the patient's finger without subjecting the finger to significant deformation. The finger is received within a finger cot (22) having a cupshaped closed end (26) and an opposite open end (24) that is rolled up upon itself and is adapted to be unrolled longitudinally along the finger to form a tubular enclosure which closely surrounds the finger. An optical source (34) and an optical detector (36) are arranged in spaced axial alignment with each other on opposite sides of the finger so that optical energy transmitted by the source (34) through the finger is received by the detector (36). The detected light is analyzed to noninvasively determine the saturation of oxygen within the patient's blood. By virtue of the nonadhesive connection between the probe (21) and the finger, decoupling the optical path between the source (34) and detector (36) is minimized in the event that the patient moves his finger duringtesting. The optical source (34) and optical detector (36) also are separable from the finger cot (22) such that the optical sensor (23) may be reused withanother finger cot.

Title: Releasable coupling
Inventor: ANGELL JONATHAN GEORGE CORDY
IPC: F16L37/092
Filed: 1994-07-07
Abstract: A releasable coupling (1) which can grip and retain an object such as a pipe (2) inserted in the hollow body (3) of the coupling, with the gripping effect being releasable such that the object can be removed from the body. A sleeve (6) is movable axially within the body (3) and carries in a plurality of holes (7) around its circumference a number of rollers (9) which are adapted to grip the surface of the pipe (2). As the pipe is inserted the rollers (9) are able to move away from the pipe surface in the body (3) to allow it to enter, but as it is withdrawn, the rollers (9) are entrained and thus brought into contact with the cam surface (5) which forces them towards the pipe axis, thereby gripping the pipe. The gripping effect is released by pushing the sleeve (6) into the body (3) to disengage the rollers (9) from the cam surface (5) thereby permitting removal of the pipe (2). An O-ring seal (14) can be included to provide a fluid-tight seal, if desired.
