Title: Ultrasonic monitor
Inventor: SUMMERS JOHN BRIAN
IPC: G01S15/36
Filed: 1996-03-29
Abstract: Ultrasonic monitors are described which are developments of those described in WO94/20021. Bursts of ultrasound pulses are periodically emitted into a monitored zone by an emitter (TX) and reflections from objects in the room are received by a receiver (RX). The phase of individual pulses of the reflected waves are measured relative to the phase of the transmitted waves in order to produce a phase-time profile (Figure 19) for each cycle corresponding to a respective burst of transmitted pulses. Individual objects in the field of view can be identified by their characteristic shape or sub-profile in the phase-time profile. The monitor can be arranged as an intruder alarm in a room by arranging for the sub-profiles in the phase-time profile to be compared with the parameters of sub-profiles representative of an intruder. False alarms associated with small objects close to the emitter/detector can be avoided by measuring the size of the object in various ways. The monitor can also be used to detect removal of a specific object from a monitored zone, for example removal of a baby from a crib. A fire can also be detected by detecting a time-shift of the entire phase-time profile.

Title: Polycrystalline diamond composite cutters
Inventor: TRUAX DAVID
IPC: E21B10/56
Filed: 1996-08-22
Abstract: An improved polycrystalline diamond composite ("PDC") cutter for an earth boring bit has a secondary PDC cutting surface 16 in addition to a primary PDC cutting surface 14. The secondary cutting surface 16 may take the form of one or more rings or other shapes such as a square, dots, a cross, a triangle, V shape, or straight or curved strips. The secondary cutting surfaces 16 are formed by compacting and sintering diamond in grooves formed at the surface of the cutter body. The cutter body may consist of at least one wafer of cemented tungsten carbide. When more than one wafer is used, the wafers may be of different grades of tungsten carbide and are bonded to form the cutter body. This reduces crack propagation through the cutter body. Different grades of diamond may be compacted and sintered in different grooves. The secondary PDC cutting surfaces also reduce erosion of the cutter bodies.

Title: Coin mechanism with magnetic locking system
Inventor: SCHWARZLI JOSEF W
IPC: G07F5/00
Filed: 1998-07-23
Abstract: A coin mechanism 10 is provided with a magnetic rocker and latch system for preventing rotation of a coin mechanism intended for use with a magnetic coin when a non-magnetic coin is deposited, or for preventing rotation of a coin mechanism intended for use with a non-magnetic coin when a magnetic coin is deposited. A magnet 54 is lodged in arm 51 of a rocker 50 which is biased away from coin recess 42 in the coin conveyor 40. The attractive force of the magnet on a magnetic coin inserted into the coin recess overcomes a biasing force on the rocker arm, causing the rocker arm to move toward the coin. In a coin mechanism intended to accept a magnetic coin, this causes a latch 55 on the magnetized arm to retract from a recess 95 in rotatable latch plate 92, allowing the plate to rotate and thus allowing the mechanism to operate. In a coin mechanism intended to accept a non-magnetic coin, this causes a latch on an opposed arm of the rocker to engage in a further recess in the rotatable latch plate, preventing the plate from rotating, and thus preventing the mechanism from working. The latch plate 92 can be provided with two recesses and the rocker with a latch on each of two opposing arms, one arm to be filed off depending on the type of coin to be accepted. The coin mechanism may be used with apparatus dispensing merchandise or with parking meters.
