Abstract: An adjustment method and system for an auxiliary power unit (APU) allows the APU speed to vary based on the inlet air temperature to the APU compressor. The APU is controlled by a control law that allows the APU speed to float within a selected range based on speed and electric power generators phase matching criteria that provides smooth power transfer between the APU and a main engine generator. The specific APU mechanical speed for a given temperature may be determined from a compressor map that identifies the optimum combination of pressure ratio, flow rate and efficiency for a given inlet temperature, and avoids running the APU near mechanical resonant vibration conditions.

Abstract: A universal input/output module may be tailored to enable or disable a pull-up or pull-down function such that distinct type digital signals reaching the digital signal processor may be changed such that the distinct digital signals are similar in nature when processed. The digital signal processor is able to enable or disable a pull-down or a pull-up function to provide the ability to universally handle these distinct digital signal types. In other features, a plurality of the modules may be associated with a common power supply, board controller and central communication bus. The input/output modules have applications such as in processing a switch or sensor signal, and outputting a control signal to an associated component.

Abstract: A blender for blending foodstuff comprising a motor housing that encloses an electric motor and has a first end and a second end. An upper housing is attached to the first end of the motor housing. The motor housing includes a fan driven by the motor controlled by a plurality of switches positioned behind a flexible cover. A transparent base having translucent base feet and an open bottom partially surrounds the motor housing and has a first end. The first end of the base is clamped between the upper housing and the first end of the motor housing to thereby solely suspend the motor housing from the first end of the base. A shroud is positioned partially around the motor within the motor housing. The fan draws air through the open bottom of the base into the second end of the motor housing and then around and outside of the shroud into the open top of the shroud to thereby cool the motor. The air is then directed out through the open side portion of the shroud and then sealingly vented to atmosphere.

A second system and method for extracting estimated an input current of an AC motor based on the actual motor input voltage, and the output voltage of the power inverter.

Abstract: A body armor assembly includes a plurality of rigid tiles that are supported in a manner to provide movement and flexibility while still providing the protection of rigid armor. In a disclosed example, a tile holder maintains a plurality of tiles in a selected alignment. The tile holder maintains a minimum overlap dimension between adjacent tiles. Some of the tiles are maintained by the tile holder in a manner that allows for the overlap dimension to increase beyond the minimum overlap dimension. In a disclosed example, at least two rigid layers have at least one ballistic material layer between them to provide a rigid armor material composition.

Abstract: A system for controlling an electric motor includes a controller and a position indicator that provides position information regarding at least one motor component to the controller. The controller utilizes phase relationships indicative of the position information to determine the actual position of the component of interest. The phase information in one example is derived from the output of a resolver that provides two output signals corresponding to sin (?) and cos (?), where ? is the angular position. Utilizing the phase relationship simplifies the task of determining accurate position information that is useful to modify motor control signals to compensate for latency when making position determinations, velocity calculations or both. The inventive system makes it possible to use less expensive electronics to arrive at more reliable results.

Abstract: An electric motor has at least one component that is submerged in a cooling fluid held in a fluid-filled cavity. The stator, rotor, and rotor shaft bearings are all possible components that may be submerged. The cooling fluid floods the stator, rotor, and/or bearings to cool the components. The fluid may have a high electrical resistance to isolate the motor components from any contact with flammable gasses as well as prevent arcs or sparks. The cavity holding the fluid also ensures continuous lubrication by preventing fluid from leaking or evaporating out of the motor.

The case layer is a metal, epoxy-based, silicone-based, or polymer material that encapsulates the coating layer and the electric element to protect the coating layer and electric element from physical damage.

Abstract: A blender jar defines a geometry to impart vertical movement to material being processed in the blender jar, and, alternatively or in combination, improves the horizontal movement to the blended material. By configuring one or more agitators on the floor of a jar, laminar flow or symmetric flow of material around the jar is disrupted. The material is forced in an upward direction in the jar and, therefore, into more frequent contact with the cutter blades rotating in the jar.

Abstract: A motor includes a housing including separate motor and bearing cooling inlets. A motor is arranged within the housing and includes a stator and rotor assembly that is supported on air bearings. The motor cooling inlet is in fluid communication with the stator, and the bearing cooling inlet is in fluid communication with the air bearings.

The bearing cooling duct is in fluid communication with a high pressure side of a ram air duct, such as through a reverse J-tube. A differential pressure between the high and low pressure sides moves cooling fluid from the bearing cooling inlet to the vent to cool the bearings.
