Abstract: Methods, systems, and computer-readable media for patient-observer monitoring are provided herein. A method creates a reference model based on interaction data of previous patient-observers. The method determines an optimal value for alertness based on the reference model. The method detects interaction data for a particular patient-observer. The method calculates an alertness value for the particular patient-observer. The method generates a warning when the calculated alertness value does not satisfy the optimal value.

Abstract: Systems and methods for a shuttle platform that is configured to allow a path for one or more passengers to load or unload from a light rail transit vehicle that runs on a shared track. The shuttle platform can move in a linear plane that is parallel to a ground level from a first position to a second position and/or the second position to the first position. The shuttle platform can be associated with a setback platform that provides a first path parallel to a centerline of the shared track and a second path parallel to the centerline of the shared track, wherein the first path is at a first height from the ground level, the second path is at a second height from the ground level, and the first path and the second path are adjacent to one another.

Abstract: Systems and methods for a shuttle platform that is configured to allow a path for one or more passengers to load or unload from a light rail transit vehicle that runs on a shared track. The shuttle platform can move in a linear plane and may be operationally engaged with a drive system comprising, a drive component and a combination position lock and drive mechanism disconnect. The drive component may comprise a transfer component. The combination position lock and drive mechanism disconnect may comprise: a drive disengage latch; a secondary lock latch selectably alternatively engagable between strikers; a manual drive receiver simultaneously operationally engagable with both the drive disengage latch and the secondary lock latch, and comprising a manual drive work output operationally engagable with the manual drive work input; and an automatic release.

Abstract: A closed loop adaptive fluid control system and method for use in hydraulic applications monitors one or more fluid characteristics, such as pressure, flow rate, accumulation time in an actuator, fill volume, etc., and compares the characteristic with a target response. A fluid characteristic sensor detects at least one fluid characteristic at a hydraulically-actuated device that is actuated by a electrically-operated. The sensor sends a device signal corresponding to the actual sensed characteristic to an electronic controller, which compares the device signal with a target response. The controller then identifies any differences between the device signal and the target response and provides a feedback signal to the electrically-operated valve to adjust the current to the valve, which in turn adjusts the electrically-operated valve so that the device signal corresponding to the sensed characteristic at the device converges toward the target response.

Abstract: A novel electrical circuit is disclosed that corrects for at least one undesired characteristic in an incoming electrical signal. In one embodiment, the apparatus reduces the number of wires heretofore required to correct electrical signals in a circuit. The apparatus also corrects for one or more of a second-order error in a measurement, an offset drift can be directly corrected during operation, and a span can be linearized during operation.

Abstract: A solenoid operated valve has a pressure transducer sensing valve outlet pressure integrally formed in the valve body, such as by overmolding. Upon connection of the transducer and solenoid to an electronic controller, the controller generates a valve energization signal in response to a desired valve pressure output and the transducer input for providing closed loop control of the valve outlet pressure. An ASIC may also be integrally formed in the valve body, such as by overmolding for providing integrated signal conditioning; and, the optional ASIC, if employed, may also include the circuitry for the electronic controller for providing a “smart” pressure control valve.

Abstract: An electro-hydraulic manifold assembly with a plurality of solenoid operated valves disposed on a manifold block and each operable to control pressure from the inlet to a separate outlet. Sensing ports are provided in each outlet with a pressure sensor sealed over the sensing port for providing a signal indicative of the sensed pressure. The pressure sensors are mounted on a interface and electrically connected to the interface. The interface has slots therein which permit the frame to be simultaneously electrically connected by bayonet connection to the terminals on each solenoid valve as the transducers are sealed over the sensing ports and the interface attached to the manifold block.

Abstract: A solenoid operated valve has a separate pressure sensing port communicating with the valve outlet port. A circuit board with a pressure transducer mounted over a sensing orifice in the board is attached to the valve body with the sensing orifice communicating with the sensing port in the valve body. The transducer thus provides a feedback signal indicative of the valve outlet pressure.
