Abstract: A system includes memory, and processing circuitry coupled to the memory, the processing circuitry configured to: determine at least one of: a cross-electrical signal measurement at a first electrode on a first lead implanted within a tongue of the patient based on a stimulation signal between a second electrode on the first lead or a second lead implanted within the tongue of the patient and a third electrode, or a strain measurement of at least one of the first lead or the second lead. The processing circuitry is configured to determine movement of the tongue based on at least one of the cross-electrical signal measurement or the strain measurement, and generate information indicative of the movement of the tongue.

Abstract: Systems and methods are provided for monitoring the effects of conductive dust deposits that compromise the ability of a trip unit to accurately detect AC current in a circuit interrupter. When a Rogowski coil is used as a current sensor in the circuit interrupter and the trip unit processes the output of the Rogowski coil using a printed circuit board assembly (PCBA) processing circuit, the DC component of the processing circuit output signal can be analyzed to determine whether any conductive dust has formed unintended electrical pathways on the PCBA and compromised the ability of the PCBA to accurately measure AC current in the circuit interrupter. It can be determined that such unintended electrical pathways have formed when the DC component of the processing circuit output either exceeds a predetermined threshold or has increased by a significant amount after opening of the separable contacts.

Abstract: A brewer, system, and method of use for producing and dispensing a beverage. The apparatus, system, and method of use includes a receiver for receiving a brewing substance container. The receiver receives the container, positions it for infusion with heated water, and then positions the container for removal from the receiver. The present apparatus, system, and method minimizes the drive mechanisms associated with the apparatus and improves the control and reliability of the apparatus. The apparatus facilitates collection and dispensing of beverage produced in the receiver and removal of the brewing substance container from the receiver.

Abstract: A reusable beverage container for use with a beverage maker to retain a beverage making substance therein. The reusable container has a container portion, a base and a cover. The base is coupled to the container portion and at least a portion of the base is foraminous. The cover is displaceably retained on the container for allowing a beverage making substance to be placed in the container and retained therein. At least a portion of the base is faraminous. The container may also be in the form of a kit for use with a beverage maker for containing a beverage making substance. The kit includes a cover displaceably retained on a holder of the beverage maker. The holder defines a cavity for retaining beverage making substance and the cover is displaceably positionable over the cavity for selectively retaining beverage substance in the holder.

Abstract: A variable capacity, vane-type compressor has a cylinder block with an oval rotor chamber. A plurality of vanes mounted in slots on a rotor rotate inside the rotor chamber on a shaft that is concentric with the minor diameter of the rotor chamber. Valves discharge refrigerant gas from the rotor chamber. The front nose block is located on the front side of the cylinder block and contains a bore for the rotor shaft and a set of needle roller bearings which supports the forward end of the shaft. A circular O-ring groove with an O-ring is located on the rearward side of the front nose block at its perimeter for sealing between the front nose block and the forward side of the cylinder block. The cylinder block has internal, weight-reducing voids located outboard of the rotor chamber. The lower voids serve as an oil sump and supply high pressure lubricant to the undervane pressurization manifolds. Like the front nose block groove, the cylinder block has a circular groove machined on a rearward side.

Abstract: A control valve for a variable rotary vane compressor is modular. The control operates an actuator to vary the position of a rotary valve plate located between the intake chamber and the compression chamber. The control valve locates in a cavity which has a suction pressure portion, a control pressure portion, and a discharge pressure portion. The control valve has an end cap and a valve seat member connected together by a sleeve. A valve element engages a seat in the valve seat member. The spring and a bias pin urge the valve element to the closed position. A bellows located within the sleeve has a stem that contacts the valve element to move it off of the seat. The sleeve allows the distance between the valve seat member and the end cap to be varied to preset the bellows prior to installation in the compressor.
