Title: Disk scanning apparatus for batch ion implanters
Inventor: FREYTSIS AVRUM
IPC: H01J37/20
Filed: 1991-05-03
Abstract: A mechanical scanning system for a batch ion implanter includes a disk (40) for mounting wafers (39) at sites (42) near its periphery and a disk drive assembly (50) for rotating the disk (40). The disk (40) and the disk drive assembly (50) are supported in an end station vacuum chamber (30) by a scan arm (44) which extends through a sealed opening (64) in an access door (60). A scan drive assembly (52) attached to the access door (60) scans the scan arm (44) and the disk (40) in an arc-shaped path. Simultaneous rotation and scanning of the disk cause the ion beam (20) to be distributed over the surfaces of the wafers (39) mounted on the disk (40). A pivot drive assembly (54) rotates the scan arm (44) and the disk (40) about a pivot axis (C) between an implant position and a load/unload position. A bellows (102) seals the scan arm (44) to the vacuum chamber (30) while transmitting arc-shaped movement into the vacuum chamber (30). A bellows guide apparatus guides an intermediate portion of the bellows so as to limit lateral distortion caused by pressure differences applied to the bellows in the combination with asymmetrical deflection thereof.

Title: Audible alert for automatic lighting shut off circuit
Inventor: ERWIN WILLIAM RANDALL
IPC: H05B37/02
Filed: 1992-12-09
Abstract: An automatic lighting controller applies a turn-off control signal to a gate controlled power switch SW1 for switching OFF lighting when a timer circuit (40) determines that motion activity above a threshold level has not occurred within the controlled area during a prescribed interval. A counter (62) produces a grace period count signal and a reset count signal, with the grace period count signal occurring with a predetermined sub-interval, for example, one count cycle prior to the reset count signal. The grace period count cycle (N - 1) interval is adjustable, for example, from about 0.6 second (for test purposes) to about 14 seconds. The grace period count signal enables an audio transducer 96 which provides an audible alert that the lights are about to be switched OFF automatically. A person in the controlled area can override the impending automatic shutoff simply by initiating some motion activity during the grace period. <IMAGE>

Title: Depth selection optical measurement system, particularly for transcutaneous measurement of substances in body tissues or fluid
Inventor: GRAVES PIERRE ROBERT
IPC: A61B5/145
Filed: 1995-11-17
Abstract: Light from a source (1), such as an LED, is directed towards an object, such as a patients's skin (5), via focussing means (2, 3) and a beam splitter (4). The light passes through the skin and is focussed at a selected depth (d) beneath the surface. Reflected or fluorescent light returning from the subject passes through the focussing means (3) and beamsplitter (4) and then optical selecting means (6), such as a pinhole, so that only light returning from the selected level (d) beneath the surface of the subject is transmitted to the detection means (10), via further lenses (7, 9) and a dispersing element (8). By selecting the level from which measurements are taken, interference from other levels can be reduced. A particular application is a hand-held device for the measurement of bilirubin, where factors which previously could affect the measurement, such as skin pigmentation and thickness, are overcome with this system.

Title: Fail-safe float temperature compensating battery charger
Inventor: FARRELL MALCOLM
IPC: H02J7/00
Filed: 1996-01-03
Abstract: During float charging of a standby battery 3 at constant charging voltage via rectifiers 5,5',5", a float temperature compensation block 1 responds to the output of battery temperature and voltage sensing means 2 to control the rectifiers 5,5',5" so that the charging voltage decreases as battery temperature increases. The block 1 controls the rectifiers via respective logic gates 4,4',4" which each have a second input from a watchdog block 6 connected to battery temperature and voltage sensing means 7. If the watchdog block 6 senses that the battery voltage does not lie within a predetermined margin of error of the voltage which should be instructed by the block 1 for the present battery temperature, the block 6 assumes that there is a failure in block 1 and turns off the gates 4,4',4' and activates an indicator 8. The rectifiers 5,5',5" then revert to an internally reset output voltage. The gates 4,4',4" also turn off in the event of a failure in block 6, or in both blocks 1 and 6. <IMAGE>
