Abstract: A dye sublimation apparatus is disclosed. The apparatus is configured to either print one or more images onto transfer media, or to print images directly onto products. A selected product to receive the image(s) is positioned on a platen configured to receive one or more types of such products into channels matching those products' dimensions. Proper positioning of the transfer media (or the product, when directly printed) is facilitated by aligning fiducial markers printed on the transfer media and/or product with one or more lights disposed on the platen. The apparatus comprises one or more heating platens configured to sublimate one or more sides of the product in a single thermal cycle with a predetermined temperature, pressure, and duration based on properties of the product. The product platen is translated inside and out of the apparatus by a reversible motor.

Abstract: A method and system for cleaning a brake booster aspirator shut-off valve are provided. The shut-off valve is operable to selectively permit flow of intake air through an aspirator; the aspirator bypasses a throttle of an engine and provides a vacuum source for a brake booster. The method comprises determining whether the shut-off valve may require cleaning, opening the shut-off valve so as to permit a flow of air through the shut-off valve and clean the shut-off valve and adjusting the throttle position of the engine to compensate for the additional flow of intake air through the aspirator.

Abstract: A stethoscope system may include an array of sensors, which may include pressure sensors. The array may be implemented in a wearable “patch” that is conformable to a patient's body. The stethoscope system may include a control system that is capable of receiving signals from the array of sensors. The signals may, for example, correspond to measurements from multiple pressure sensors of the array. The control system may be capable of combining signals from multiple pressure sensors to produce combined signals. The control system may be capable of filtering the combined signals to remove, at least in part, breathing signal components and to produce filtered signals. The control system may be capable of determining a correspondence between heart signal components of the filtered signals and corresponding heart valve activity.

Abstract: Systems and methods to determine a location of a mobile device by combining a radio frequency navigation system and an inertial navigation system, where the radio frequency navigation system determines a location of the mobile device in reference to a map of radio frequency signals and the inertial navigation system based on dead reckoning the position of the mobile device based on measurements from motion sensors. When the radio frequency navigation system produces accurate results, the mobile device automatically re-initializes the inertial navigation system using the accurate result from the radio frequency navigation system.

Abstract: Systems and methods to determine a location of a mobile device by combining a radio frequency navigation system and an inertial navigation system, where the radio frequency navigation system determines a location of the mobile device in reference to a map of radio frequency signals and the inertial navigation system based on dead reckoning the position of the mobile device based on measurements from motion sensors. When a set of successive locations determined by the radio frequency navigation system is found to have a predetermined pattern (e.g., within a minimum distance from each other, or separated by more than a maximum distance), the mobile device discards the location results from the radio frequency navigation system for the period of time, in favor of the location results from the inertial navigation system.

Abstract: Systems and methods to determine a location of a mobile device by combining a radio frequency navigation system and an inertial navigation system, where the radio frequency navigation system determines a location of the mobile device in reference to a map of radio frequency signals and the inertial navigation system based on dead reckoning the position of the mobile device based on measurements from motion sensors and/or magnetic field sensors. The mobile device combines the position determination results from the radio frequency navigation system and the inertial navigation system to determine two successive locations. A heading of the user of the mobile device is computed from the two successive locations without using the orientation of the mobile device.

Abstract: A collision avoidance system comprises a pair of video cameras mounted to a vertical stabilizer of the aircraft, a machine vision processing unit, and a system to inform the pilots of a potential collision. The machine vision processing unit is configured to process image data captured by the video cameras using stereoscopic and structure from motion techniques to detect an obstacle that is near or in the path of the aircraft. Estimates of the range to the object and the rate of change of that range are computed. With the range and range rate, a time to collision can be estimated toward every point of the aircraft. A pilot warning can be sounded based on the nearness of the potential collision. A method of calibrating the video cameras using existing feature points on the top of the aircraft is initiated in response to power being turned on.
