摘要： Mating air ducts may be joined to each other via an integrally formed protrusion on male air duct and an integrally formed groove on a female air duct for effecting linear and angular alignment of the mating air ducts. The integrally formed protrusion and groove may be formed on the air ducts via a process known as selective laser sintering or stereo lithography. Further, more than one groove and protrusion may be formed on the air ducts in an uneven manner such that the protrusions fit within the grooves in only one angular orientation. The protrusion may be a nub or a thread. Also, the groove may be a channel aligned to a central axis of the female air duct or a helical groove. The male air duct is linearly aligned and/or angularly aligned to the female air duct when the protrusion engages a distal portion of the groove or an abrupt change of the groove.

摘要： A system and method is provided for a gesture recognition interface system. The interface system may comprise a first and second light source (16,18) positioned to illuminate a background surface (20). The interface system may also comprise at least one camera (12,14) operative to receive a first plurality of images based on a first reflected light contrast difference between the background surface (20) and a sensorless input object caused by the first light source (16) and a second plurality of images based on a second reflected light contrast difference between the background surface (20) and the sensorless input object caused by the second light source (18). The interface system may further comprise a controller (24) operative to determine a given input gesture based on changes in relative locations of the sensorless input object in the first plurality of images and the second plurality of images. The controller (24) may further be operative to initiate a device input associated with the given input gesture.

摘要： Systems and methods are provided for providing high dynamic range operation over a variable range of frequencies. A delta-sigma modulator, having associated frequency characteristics, produces a digital output signal. A digital-to-analog converter converts the digital output signal into an analog signal. A clock circuit provides a clock signal to the delta-sigma modulator and the digital-to-analog converter. A frequency control controls one or more of the clock circuit, the delta-sigma modulator, and the digital-to-analog converter to alter the frequency characteristics of the delta-sigma modulator. A filter circuit can provide one or more passbands to one or more downstream amplifiers ensuring that out of band quantization noise is removed before amplification.

摘要： A light beam on a single optic fiber carries time division multiplexed information originating from multiple sensors driven from a single light source. An optical switch apparatus coupled in series between the source and the sensors switches the light beam of the source between ON and OFF states. The switch apparatus includes an electro-optic switch and an acousto- optic switch coupled in series with the electro-optic switch. A controller and drivers for the electro-optic and acousto-optic switches produce in an appropriate time sequence control signals resulting in a desired ON and OFF time of the light beam being switched.

摘要： A multiple station gamma ray absorption contraband detection system utilizes a proton source (200) and disk-shaped target (100) to provide a 360 degree resonant gamma ray cone which is suitable for use in four separate gamma ray absoprtion contraband detection stations (202, 204, 206, 208) simultaneously. The target has two beryllium walls coated with 13C and 34S so as to facilitate the detection of nitrogen and chlorine in a manner which reliably and effctively identifies contraband such as explosives and drugs via gamma ray absorption.

摘要： A laser system (10) for operation at elevated temperatures with minimal cooling requirements. The laser system (10) comprises a laser media (34) having first and second optical ends (66, 68) and an input port (64). The laser system (10) further comprises at least one hightemperature laser diode which optically communicates with the laser media (34) and is operative to generate a source beam of light which is transmitted into the input port (64) of the laser media (34). Optically communicating with the first optical end (66) of the laser media (34) is at least one reflector (36), while optically communicating with the second optical end (68) of the laser media (34) is at least one optical coupler (50). The laser media (34), the reflector (36) and the optical coupler (50) are configured to form a laser resonator operative to generate a laser beam which is transmitted through the optical coupler (50).

摘要： A personal communication system provides full duplex digital communications between multiple users for both audio and data. A universal adaptor interface (12a) receives a plurality of wireless communications. The wireless adaptor interface (12a) multiplexes the plurality of wireless communications into a composite signal. The universal adaptor interface (12a) transmits the composite signal wirelessly. At least one personal communications unit (10a) receives the composite signal. Multiplexing the plurality of wireless communications facilitates simultaneous reception thereof by the personal communication units.
