Abstract: An optical based identification system that is easily deployable and can be used in broad daylight. Fluorescent semiconductor nanocrystals (quantum dots) that fluoresce at specific wavelengths are distributed in a suitable polymer. The resulting mixture can then be applied as paint or on an adhesive label for application to a portion of any equipment or member of a friendly unit. The system also has a corresponding detectional processing unit which may be mounted on ordnance or on any other equipment such as aircraft. The detection unit uses a laser, which when active, causes a laser beam to strike the paint or adhesive able applied to the friendly unit. This causes the quantum dots to fluoresce. The fluorescence of the quantum dots can be detected by the sensor portion of the detection/processing unit. The sensor portion then transmits the data generated. by the detected fluorescence to a data processing portion detection/processing unit such as a corresponding signal to the equipment operator or, if the unit is mounted on ordnance that has been launched to the warhead to deactivate the warhead. To overcome the effects of broad daylight on an optical system, the quantum dots can be detected by the sensor portions of the detection/processing unit. The sensor portion then transmits the data generated by the detected fluorescence to a data processing portion which decodes the data. if the decoded data indicates a friendly unit, the detection/processing unit sends a corresponding signal to the equipment operator or, if the unit is mounted on ordnance that has been launched to the warhead to deactivate the warhead. To overcome the effects of broad daylight on an optical system, the quantum dots are engineered to fluoresce at wavelengths corresponding to the absorption lines of the solar spectrum, more commonly known as Fraunhofer lines.

Title: Nose pad assembly for an eyeglass frame
Inventor: NEGISHI TOHRU
IPC: G02C5/12
Filed: 2004-09-07
Granted: 2011-01-25
Abstract: A nose pad assembly is slidably mounted to an eyeglass frame by which a pair of multifocal lenses are held. The nose pad assembly includes a pair of oval nose pads within which elongated guide grooves are defined. Two pairs of upper and lower magnets are coaxially and fixedly mounted in the upper and lower ends of the respective nose pads. A pair of slides are slidably moved along the guide grooves and attached to a pair of pad arms of the eyeglass frame. The slides include a corresponding pair of slide magnets positioned within the respective guide grooves. The slide magnets are selectively attracted to the upper and lower magnets to hold the eyeglass frame in its upper and lower positions, respectively. A bridge member extends between the upper end of the nose pads. The bridge member is configured to resist a substantially vertical force which may be applied thereto when the eyeglass frame is moved between its upper and lower positions. The bridge member is free to flex in a substantially horizontal direction so that orientation of the nose pads can readily be adjusted.

Granted: 2010-03-16
Abstract: A torque transfer mechanism having a multi-plate friction clutch connecting a pair of rotary members and a electrohydraulic clutch actuator for controlling engagement of the friction clutch. The clutch actuator includes a hydraulic pump, a hydraulically-actuated rotary operator, and a thrust mechanism. The hydraulic pump draws low pressure fluid from a sump and selectively delivers high pressure fluid to a series of actuation chambers and return chambers defined between coaxially aligned first and second components of the rotary operator. The magnitude of the fluid pressure delivered to the actuation chamber controls angular movement of the second component relative to the first component for energizing the thrust mechanism. The thrust mechanism applies a clutch engagement force on the friction clutch, thereby transferring drive torque from the first rotary member to the second rotary member. An electrohydraulic control system regulates the fluid pressure delivered to the actuation and return chambers.
