Abstract: An apparatus includes a disposable assembly and a reusable assembly. The disposable assembly includes a fluid input port, a fluid output port, and a tube configured to provide fluid communication between the fluid input port and the fluid output port. The reusable assembly includes a housing, a fluid management assembly that is configured to transition between an open position and a closed position, and a sensing assembly. The fluid management assembly is configured to prevent fluid from traveling past the tube to the fluid output port in the closed position. The sensing assembly is configured to sense fluid accumulating within the tube while the fluid management assembly is in the closed position. The sensing assembly is also configured to drive the fluid management assembly from the closed position to the open position when the sensing assembly detects fluid within the tube at a predetermined range.

Abstract: A non-contact sensing system acquiring three-dimensional information includes a laser light source and fiber generating a Gaussian optical beam. A movable mirror is angularly adjusted to scan the beam to an area of illumination. A lens package between the light source and the movable mirror focuses the optical beam to under-fill a movable mirror optical surface and control an optical beam scanned volume. The optical beam reflected by the movable mirror is redirected using a fold mirror orthogonal to an optical beam orientation. The optical beam is maintained Gaussian by the mirrors and lenses. An imaging device having a field of view intersecting the area of illumination receives optical beam image data reflected from the area of illumination. A control module communicating with the imaging device receives an object location in the imaging device field of view from the image data and reports object location data to a coordinate system.

Abstract: A telescope design having an integrated baffle is disclosed herein. The integrated baffle is configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between the primary and secondary mirrors of a given telescope design. The baffle design can be adjusted to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput. The interior facing surfaces of the integrated baffle can be configured with corner reflectors, so that the detector views itself, instead of the baffle.

Abstract: A telescope design is disclosed that has at least some of its interior facing surfaces configured with corner reflectors, so that a detector operatively coupled to the telescope views itself, instead of those surfaces. The corner reflectors may be on, for example, interior facing surfaces of a conventional baffle appended to the telescope and/or mirror supports or other structures inside the telescope housing that are within the detector's FOV. Likewise, the corner reflectors may be on interior facing surfaces of a baffle that is integrated into the telescope housing. In some such cases, the integrated baffle can be configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between mirrors of a given telescope design, and/or configured to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput.

The corner reflectors may be on, for example, interior facing surfaces of a conventional baffle appended to the telescope and/or minor supports or other structures inside the telescope housing that are within the detector's FOV. Likewise, the corner reflectors may be on interior facing surfaces of a baffle that is integrated into the telescope housing. In some such cases, the integrated baffle can be configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between minors of a given telescope design, and/or configured to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput.

Abstract: A sensor is used to detect and track a plurality of objects by using a separate track window for each object. Such sensors may be electro optical or infrared. Each object of interest (potential target) in the sensor FOV has a unique track window assigned. This allows independent control of video frame summing for each object to maintain a constant (optimized) signal to noise ratio (SNR) over an extremely large signal dynamic range and reduces track jitter by the simultaneous tracking of multiple objects.

Abstract: A light source is injected into an optical path of a camera to provide a controlled background to insure optimum uniformity of performance of the camera. An optical system, camera, image background measurement system, source intensity control, and light source comprise a closed loop control around the light source to control an operating point of the camera. Intensity of the light source is decreased as intensity of a background flux is increased.

Abstract: A body composition analyzer provides the resistive and reactive components of a body's measure impedance as well as body fat information and ideal weight information. The analyzer includes an analog circuit under the control of a microprocessor for providing signals to the microprocessor that are representative of the voltage across the network formed by the body and of the voltage across a reference network of known impedance that is connected in series with the body network. The microprocessor calculates the body networks impedance as a function of the ratio of the body network voltage and reference network voltage signals to provide extremely accurate results. The body composition analyzer is a hand-held unit that can transmit data to a peripheral device for recording via a wireless communication network. The analyzer is further programmable so that various algorithms and constants stored therein can be updated.

Abstract: An electrical rotary switch includes a single support housing (18) for rotation about a base (12). The base (12) is a circuit board which includes an opening (16) through which the housing (18) is secured to the base. A pair of contact pads (14) extend radially away from the opening (16) on the base (12). The housing (18) includes a cavity (34) facing the base (12). A conductive roller (38) is located in the cavity (34) for rolling over the pair of contact pads (14) to establish an electrical connection. The switch is characterized by a fulcrum ridge (40) extending from the housing (18) into the cavity (34) for allowing the roller (38) to rock in case a bump is incurred in the contact pads (14) to ensure an electrical connection.
