Abstract:
The present speckle reduction device comprises an optical element intended to be passed through by the coherent light beam to be treated. It also includes means able to cause heating of the said optical element; and a cooling element coupled to the said optical element so as to be able to cool the latter. A control module is configured to control the heating means and the cooling element so as to create thermal perturbations in the optical element, causing corresponding variations in the refractive index of the said optical element. The optical element is a piezoelectric crystal which is excited in a specific deformation mode causing its heating.

A system to align a vehicle in a parking location includes a plurality of heat generating devices, such as infrared LEDs, arranged in a surface of the parking location to produce a distinctive thermal pattern. A multiple zone temperature sensor is mounted to view the heat generating devices and is configured to output thermal data for each of the zones. A controller is configured to receive the thermal data and determine a thermal map of the plurality of heat generating devices. A display provides a graphic indication of the thermal map and a thermal alignment target. The system may be used to align a vehicle having a capture resonator of a wireless power transfer system to a parking location having a source resonator of a wireless power transfer system.

A wire cable assembly including a wire cable and a contact element. The contact element is configured to axially receive the wire cable and is formed to attach the wire cable to the contact element. A portion of the contact element is formed to define a single pair of indentation arrangements. The pair of indentation arrangements consists of a first indentation arrangement that diametrically opposes a second indentation arrangement. The contact element may also define a pair of humps adjacent to each of the grooves in the single pair of grooves. The wire cable may further include a conductive inner core, a first insulation layer surrounding the inner core, and an outer wire layer surrounding the first insulation layer. The wire cable assembly may further include an inner ferrule and an outer ferrule with the outer wire layer disposed between the inner ferrule and the outer ferrule.

Abstract:
Pressure sensitive transducer assembly that includes a force sensing resistor. The force sensing resistor includes: first and second substrates; at least a first and a second electrically conductive traces on the inner surface of the first substrate including interdigitated fingers defining a sensitive area; and a resistive layer facing the sensitive area. The force sensing resistor includes an auxiliary trace on the inner surface of the first substrate connecting the first trace to the second trace through a constant resistance that is not dependent on the force applied to the substrates. The constant resistance being of a value largely greater than the value of the variable resistance which can be measured indirectly between the fingers when an external force is applied to the substrates. A system and a control method are also proposed.
Abstract:
A ground fault circuit interrupter (GFCI) includes a sense coil to determine a current flow in a power circuit coupled between a power source and a load. The GFCI also includes a switching device configured to disconnect the power source from the load. The GFCI further includes a controller that controls the switching device based on the current flow in the power circuit. The GFCI additionally includes an electrical power supply that provides electrical power to the switching device. The power supply is electrically separate and isolated from the power circuit. The GFCI may be used to monitor a power circuit connected to a tuned resonant circuit, such as a source or capture resonator of a wireless power transfer system, since inductive elements in the switching device, such as solenoids, are isolated from the power circuit and therefore cannot unbalance a tuned resonant circuit connected to the power circuit.
Abstract:
A fluid pump includes an inlet for introducing fluid into the fluid pump and an outlet for discharging fluid from the fluid pump. The fluid pump also includes a motor having a shaft that rotates about an axis. An impeller includes an array of blades radially surrounding the axis. The impeller is rotatable by the shaft of the motor such that rotation of the impeller pumps fluid from the inlet to the outlet. A vibration isolation member applies a force on the shaft such that the force has a component that is perpendicular to the axis.

A horizontal scroll compressor assembly for compressing a working fluid and lubricated with an oil, including a housing having an axis, an interior surface, and a suction sump for collected oil located in the suction plenum, and a compression mechanism including an orbital scroll member having a thrust surface, the thrust surface and the housing interior surface axially superposed. The thrust surface is provided with an oil distribution channel extending at least partially about an axis. Oil from the suction sump received into the distribution channel urged along the distribution channel and delivered to locations between the superposed surfaces during movement of the orbital scroll member about the axis relative to the housing. Also, a method for distributing oil in a scroll compressor assembly including: receiving oil from a suction sump into an oil distribution channel located in the thrust surface of an orbital scroll member; pumping oil along the oil distribution channel to locations between the thrust surface and a superposed housing surface; and lubricating a thrust surface interface with oil pumped to locations between the thrust surface and the superposed housing surface.
Abstract:
A sensor assembly that integrates a camera and a radar sensor is described herein. The sensor assembly includes a housing configured to partially enclose the camera and the radar sensor, and define a partial radome that partially intrudes into the radar beam. The partial radome is configured such that after passing through the partial radome a first phase angle of the first portion of the radar beam differs from a second phase angle of the second portion of the radar beam by an amount substantially corresponding to an integer number of three hundred sixty degrees (360°) of phase angle shift. The partial radome provides glare shield to the camera, protection to assembly, and is configured to minimally effect radar performance.
