Abstract: A method of coating a seal slot according to an exemplary embodiment of this disclosure, among other possible things includes applying a coating to a slot in a component and machining the coating to provide an open width configured to receive a seal. after the applying, the slot has an initial open width that is smaller than the open width after the machining. A method of forming a sealing assembly is also disclosed.

Abstract: Disclosed herein are embodiments of systems, methods, and products that generate semantic resolutions of wireless signals. An analytic server may train a plurality of inductive classifiers generate a respective set of deduction rules. For example, the analytic server may train a first inductive classifier to mine a first set of deduction rules matching service set identifiers (SSIDs) with business entities. As another example, the analytic server may train a second inductive classifier to mine a second set of deduction rules matching proximal groupings of wireless signals (also referred to as hyperclusters) with business entities. Upon receiving an unresolved wireless signal, the analytic server may apply at least one of the first and second set of deduction rules to assign a semantic meaning to the wireless signal.

Abstract: The present invention is directed to segmented waveguide for a fiber optic rotary joint. The segmented waveguide is mountable to the existing stator surface. The segmented waveguide is capable of receiving signals from the rotor. The fiber optic rotary joint includes a rotor and an existing stator surface. The rotor is rotatable through a full 360° and is concentric to the existing stator surface. The rotor has one of a plurality of light transmitters and light receivers connected to a first circumference of the rotor. The segmented waveguide includes a reflective waveguide surface shaped to match a potion of existing stator surface. At least one waveguide support supports the reflective waveguide surface and is connectable to the existing stator. At least one of a light transmitter or light receiver is optically coupled to a reflective waveguide surface.

Abstract: A hybrid fiber optic transceiver is described which includes a transmitter for converting electrical data signals to corresponding light energy, a receiver for converting optical data signals back to electrical data signals and a clock recovery mechanism to maintain the electrical data signals outputs from the receiver in their proper order. The transceiver includes an optical splitter or coupler that allows light signals to be transmitted and received over a single fiber. The opto-electrical hybrid circuitry of the transceiver and the fiber optic coupler are enclosed in a small light weight package which is hermetically sealed.

Abstract: A motorized vehicle, particularly a wheelchair, having a joystick controller for controlling energization of driving motors which in turn drive vehicle wheels and control steering of the vehicle. The joystick controller includes fiber-optic arrangements which sense tilting movement of the joystick in forward, rearward, rightward or leftward directions, or a combination thereof. Light signals are generated of an intensity corresponding to the position of the joystick, which signals are converted into electric signals and supplied to a controller which in turn controls energization of the drive motors to control driving and steering of the vehicle.

Abstract: A fast acting solid state AC circuit breaker includes a power transistor module in series with a load. Load current is continuously monitored and compared with threshold current values which define maximum current for equipment turn-on and steady state conditions. The steady state conditions may be briefly exceeded to allow normal transient overloads to exist on the line for periods up to 25 milliseconds. A maximum current level greater than the normal transient overload can exist on the line for 10 milliseconds after the circuit breaker turns on. The circuit breaker can be turned off in less than 10 microseconds.
