Title: Ring laser interferometer with external feedback
Inventor: SON JUNG YOUNG
IPC: H01S3/083
Filed: 2000-05-09
Abstract: A ring laser interferometer comprises a ring laser cavity formed by a plurality of internal mirrors 233 234 235 236 of which at least two 235 236 are partially transmitting and has two counter-propagating laser beams 261 262 of the same wavelength. At least one external mirror 244 245 reflects the fraction of the laser beams escaping from the transmitting mirrors back into the ring laser cavity, possibly via retro-reflectors 240 241. The length of an optical path between the external mirror and ring laser is controlled by the physical quantity to be measured, such as displacement, length, position, temperature, refractive index or pressure, possibly through displacement of the retro-reflector mounts 273 274 (and figure 11b) or through a test gas in a measurement cell (see figures 12a,b). The ring laser is preferably operated under lock-in and is insensitive to rotation of the ring laser.

Patent GB-2379726-A (GB)
Title: Electro-magnetically operated device
Inventor: WYGNANSKI WLADYSLAW
IPC: H01H51/22
Filed: 2001-07-05
Abstract: An electro-magnetically operated device is described in which a magnetisable armature 10 in the form of a length of thin naturally resilient mild steel, is sandwiched between, and extends from, two parts of a magnetic circuit which contains an air gap 28 into which the armature extends. An electromagnet polarizes the armature along its length so as to cause the end thereof in the air gap to be attracted to one or the other of the two poles 24,26 of the magnetic circuit defining the gap. The armature is designed so as to be capable of adopting a mid-position between the poles of the air gap if the current flowing in the electromagnet is reduced to zero. Equalising the air gaps and adjusting the size of the gap relative to the resilience of the armature will produce a bistable characteristic in which the armature will not remain in the mid-position, but will always remain in contact with one pole or the other, and is shifted from one to the other by a pulse of current of appropriate polarity. Adjustment of the size of the air gap on one side or the other of the armature introduces an out of balance in the magnetic circuit enabling the device to adopt a monostable characteristic instead of a bistable characteristic. Movement of the armature can open and/or close valves, controlling a flow of fluid.

Title: Infrared LED driver for a remote control transmitter
Inventor: KATAOKA YASUTAKA
IPC: H01L33/00
Filed: 2003-01-17
Abstract: The invention provides a simple and stable infrared light emitting diode (LED) drive circuit for preventing an LED from emitting a continuous intense infrared light when a fault occurs. The driver circuit comprises a voltage source 2, a first transistor 5 connected in series with an LED 4, a second transistor 7 connected in parallel with the LED and a set of operation keys 8 for generating pulse signals. During normal operation when any of the operation keys are pressed a pulse is applied to the base of the series transmitter resulting in current flowing to the LED. If the emitter and collector of the series transistor are short circuited however, the parallel transistor becomes active to prevent current flowing to the LED when operation keys are not pressed. Application is to a remote control transmitter or other communication appliance such as an electronic notebook or personal digital assistant.
