Abstract: A self-reacting center wheel nut assembly includes a reaction ring (120) formed between a center wheel nut (110) and a lock collar assembly (130). The self-reacting center wheel nut assembly may also include a washer (140) and O-rings. The self-reacting center wheel nut assembly improves and simplifies wheel bolt tightening; uses the lock collar assembly as a reaction point by transferring opposing torque generated during installation and removal through the reaction ring, which is reacted on by a dual sleeved drive assembly; may be used with HYTORC electric battery powered torque multiplier gun/tools to deliver quick, accurate and precise torque; eliminates the need for external reaction points such as the rim or ground, thereby eliminating side loads and damage to the wheel; is fully sealed and lubricated; eliminates vehicle movement and the need to lock the brakes; reduces operator fatigue, chances of injury and saves operator time and energy.

Abstract: A quick disconnect apparatus including a first end configured to interface with a legacy fill and drain valve (FDV) of a satellite to be serviced, a second end configured to interface with a refueling tool, and a middle portion including at least one redundant seal to prevent unwanted fuel transfer during connection of the FDV and refueling tool.

Abstract: The resonant frequency of a reactive circuit is determined in situ by determining phase angle differences between an A.C. driving voltage applied to a transformer primary winding and an induced alternating current in the transformer secondary winding. The phase angle is determined indirectly by detecting when the driving voltage applied to the primary changes its polarity and when an induced current in the secondary changes its polarity. The time difference between those polarity changes indicates whether the voltage leads or lags the current or is in phase. A driving voltage frequency is adjusted in real time until the phase angle differences disappear. A duty cycle of the driving signal applied to the primary is also adjusted to change the voltage induced in the secondary winding. The duty cycle is adjusted by changing either a phase of primary driving voltages or the duty cycle of primary driving voltages.

Abstract: Methods and systems for power conversion are disclosed, including receiving at least one interrupt indicative of a transient power condition of the power converter and switching the processor to operate in a second mode from a first mode responsive to the interrupt. The switching enables the processor to allocate greater resources to process a power output parameter of the power converter operating in the transient power condition compared to resources allocated by the processor operating in the first mode to process the power output parameter.

Abstract: Disclosed herein is an electrical system topology for voltage regulation in a 12-volt vehicle power distribution system. Particularly, a single transistor power converter is configured to operate in both as a traditional voltage regulator mode (i.e., as buck converter to reduce the field voltage applied to an alternator to a value less than that available from the main bus) and as an alternator field current boost converter (i.e., as a boost converter to boost the field voltage applied to an alternator to a value greater than that available from the main bus). The converter may also include a controller that incorporates a thermal model of the alternator to limit the amount of voltage boost applied and/or direct temperature measurement of the alternator or alternator components. Additionally, these two approaches may be combined such that measured temperatures are used to refine the temperature estimated by the thermal estimator.

Abstract: The position of a rotor of a motor is determined. The motor includes a stator having a plurality of coils. The rotor includes at least one rotating magnetic field device. When the rotor is moving below a threshold speed, the current in the coils is measured. A pre-programmed data structure is accessed. The data structure stores stator currents associated with predetermined rotor positions. A first absolute position of the rotor is determined from the data structure according to the measured current from each of the coils. When the rotor is moving above the threshold speed, one or more rising or falling edges of magnetic field strength associated with the at least one rotating magnetic field device are sensed. At least one timing aspect of the rising and falling edges of magnetic field strength are compared to determine a second absolute position of the rotor.

Abstract: Disclosed herein are a variety of different electrical system topologies intended to mitigate the impact of large intermittent loads on a 12 volt vehicle power distribution system. In some embodiments the intermittent load is disconnected from the remainder of the system and the voltage supplied to this load is allowed to fluctuate. In other embodiments, the voltage to critical loads is regulated independently of the voltage supplied to the remainder of the system. The different topologies described can be grouped into three categories, each corresponding to a different solution technique. One approach is to regulate the voltage to the critical loads. A second approach is to isolate the intermittent load that causes the drop in system voltage. The third approach is to use a different type of alternator that has a faster response than the conventional Lundell wound field machine.

Abstract: The APPARATUSES, METHODS AND SYSTEMS FOR AN ACTIVITY TRACKING AND PROPERTY TRANSACTION FACILITATING HUB (“HUB”) facilitates the generation, evaluation, and recording of information and activities related to property transactions and associated communications. In one implementation, the HUB dynamically generates an interface based on a user role, allows quick and efficient viewing of information relevant to an actual or potential property transaction, and records user activities or interactions to allow future access to a given interface state or set of relationships defined by interface element values, such as they may pertain to the given property transaction, an associated counterparty or contact, and/or the like. In one implementation, the HUB may provide a bifurcated display to allow for side-by-side visualization of required and available property information, attributes, and/or the like.
