Abstract: A collection of wirelessly connected devices monitored and controlled by a proportional-integral-derivative (PID) control loop application software executing on a wirelessly connected non-dedicated controller, that combine to form a wireless feedback control system that can manipulate the orientation of a vehicle frame to desired state. An inertial measurement unit (IMU), with six degrees of freedom, measures attitude with respect to gravity, is paired with wirelessly connected control mechanisms that effect the attitude of the vehicle, when controlled by software application that executes on the user provided smart phone or tablet, a closed loop control system is created that is completely wireless and where the controlling element is user provided and not dedicated to the system.

Abstract: A retention strap for NTSB standard hitch safety pins. The retaining head has a ? inch and ½-inch hole for the most common hitch pins, and ¼-inch hole for storage of a backup safety clip. The retaining head contains magnets to ensure retention of the hitch pin under most force conditions. Additionally, the magnets can retain the safety clip. The magnets also allow the device and pin to be temporarily secured to any metal surface. The large securing loop allows for multiple options for connection to the hitch or receiver.

Abstract: A device that controls the electrical connections to an accessory actuation solution, with integrated motion detection as an activation interlock, and diagnostic monitoring of the accessory. The device can use relays, or electronic drive solutions, to control electric or electro-hydraulic actuation devices. The device measures accelerations, rotations, voltages, currents, pressures, temperatures and other signals to provide diagnostic information about the accessory being controlled and vehicle to ensure safe operating conditions exist to activate the device. The device prohibits activation of the actuator if motion above a threshold is detected in more than one degree of freedom.

Abstract: A dual mode medical oxygen delivery system includes an oxygen supply, a first delivery device, and a second delivery device. A connector includes a valve member and defines a first passage extending from a supply port to a first port and a second passage extending from the supply port to a second port. An oxygen supply conduit interconnects the oxygen supply with the supply port. A first delivery conduit interconnects the first port and the first delivery device, and a second delivery conduit interconnects the second port and the second delivery device. The valve member is movable between a first position corresponding to a first operation mode in which the first passage is fluidly open and the second passage is fluidly blocked, and a second position corresponding to a second operation mode in which the first passage is fluidly blocked and the second passage is fluidly open.

Abstract: A gauge assembly includes an indicator for providing an indication of an amount of fluid in a tank and a stop-fill assembly for stopping the flow of fluid flowing into the tank once the fluid reaches a particular level. The gauge assembly has a shaft that rotates as the fluid level changes in the tank. The indicator translates the rotational position of the shaft into a fluid level. The stop-fill assembly moves from an open position, where fluid can flow into the tank, to a closed position, where fluid is prohibited from flowing into the tank, depending on the rotational position of the shaft.

Abstract: A combination tank valve apparatus providing fluid flow control, overfill protection, and fluid level gauging for use on a storage tank for liquefied gas, the storage tank having an internally threaded outlet port. The apparatus includes a service valve having a body defining a tank connection, a valve seat, a valve outlet, and a pair of wrench flats. The apparatus also includes an overfill protection device mounted to the tank connection of the service valve and including a float, a shaft, a overfill valve, and a shaft magnet. The apparatus also includes a dial mounted on the body of the service valve and having a body, a dial magnet, and a pointer, the pointer being mounted on the dial magnet to rotate with the dial magnet and provide a visual indication of the liquid level within the tank.

Abstract: A system for determining a fluid level in a pressurizable container comprising is disclosed. The system includes a service valve having a set of wrench flats defining parallel flat surfaces, one of the wrench flats having a recess defined entirely within its flat surface, a stop-fill device interconnected with the service valve and operable to rotate a first magnet inside the service valve in proximity to the recess in proportion to the amount of fluid in the pressurizable container, and a dial assembly having a dial face and a pointer attached to a second magnet, the second magnet housed in a magnet protrusion on a side of the dial face opposite the pointer and operable to fit into the recess in the service valve such that the dial moves on the dial face proportionately to the degree of rotation of the first magnet inside the service valve.

Abstract: A float-type liquid level gauge assembly is provided for measuring the level of a liquid in a tank. The liquid level gauge is designed to reduce inventory requirements and to speed the assembly process. The gauge includes a gear housing having a lower longitudinal passageway, a shaped drive shaft, a shaft head with a first receptacle and a pinion gear with a second receptacle. The shaped drive ends mate with the first and second receptacles such that the drive shaft may be inserted into the receptacles at two or less orientations. The length of the first receptacle is less than the length of the lower longitudinal passageway, so that if the drive shaft slips down in the first receptacle the drive shaft will not completely fall out of the first receptacle.

Abstract: A brake light warning system for safety helmets includes a transmitter module adapted for mounting to a vehicle, such as a motorcycle, and a receiver module adapted for mounting to a safety helmet. The transmitter module is configured to continuously transmit a transmission signal when a brake of the vehicle is disengaged and discontinue transmission of the transmission signal when a brake of the vehicle is engaged. The receiver module is configured to detect a presence or absence of the transmission signal from the transmitter module. The receiver module has at least one light generating element that illuminates or increases in brightness upon detection of the absence of the transmission signal to indicate that the vehicle brake is engaged.

Abstract: An indicator for displaying either low liquid level or satisfactory liquid level conditions within a tank includes a sensor for detecting the liquid level conditions, a photodetector for detecting an ambient dark condition, a pair of indicator lights for indicating either the low liquid level or satisfactory liquid level conditions, and electrical circuitry operable to illuminate one of the indicator lights upon detection of the ambient dark condition by the photodetector and detection of either the low liquid level condition or satisfactory liquid level condition by the sensor.

Abstract: A spring disk clamp is provided for securing one or more data storage disks to a disk drive without the need for screws. The disk clamp incorporates an angled surface defining the central opening of the clamp which is positioned adjacent a sloping surface of the hub. An external axial load applied to the clamp deflects the clamp, and allows a retaining member to be wedged between the clamp and the hub. Stabilizing features such as O-rings and the like are also eliminated as the clamp of the invention provides both radial and axial stabilization to the disk pack in its mounting to the hub.

Abstract: A method for installing a printed circuit board assembly on a disk drive base plate is disclosed, as well as the corresponding structure used for this installation. Generally, the printed circuit board assembly includes a pair of bosses that are each disposed within a corresponding concave slot on the base plate. When installing the printed circuit board assembly, the bosses are disposed within their corresponding slot while the printed circuit is disposed at an angle relative to the base plate. Thereafter, the printed circuit board assembly is pivoted toward and into interfacing relation with the base plate at least generally about the bosses.
