Abstract: A smart device is provided with an application program for displaying a video feed received from the smart device's camera. The application can determine the coordinates for an intersection point, which is a point on the ground where the smart device is pointing at. The application can display a target on the visual representation of the intersection point. Based on whether the smart device is at an appropriate distance from the intersection point, the user interface can superimpose an indicator on the video feed received from the camera. This can inform the user whether the smart device is at an optimal scan distance from the intersection point (or an object) so that the object can be identified by a machine learning model.

Abstract: Light emitting diode (LED) apparatuses and methods having a high lumen output density. An example apparatus can include a substrate with one or more LEDs enclosed by an encapsulant. The encapsulant comprises beveled edges and/or top surface facets. By providing facets in the encapsulant and minimizing the chip-to-area ratio through efficient via placement, a high lumen density is achieved. Facets and bevels can be created by removing material from the encapsulant with a beveled blade.

Abstract: Sound muffling flooring underlay tile systems using sonic foam-enhanced underlay board may comprise a sound-muffling tile assembly for installation underneath a floor surface to help minimize sound transfer between living areas and to provide increased insulation. The sound-muffling tile assembly may comprise a flooring base member, a cushioning film layer, and a fastener for securing the flooring base member to the cushioning film layer. In one embodiment of the present invention, the cushioning film layer may comprise a foam substance comprising an open-cell structure. In addition to actively dampening sound waves that travel through the open-cell structure of the foam substance, the cushioning film layer provides a floated surface for the floor above the sound-muffling tile assembly when installed.

Abstract: An LED lighting system using a retro-formed component is disclosed. Embodiments of the invention make use of a component that has an external form factor of a structural element of a pre-existing light fixture. The component, for example, can be a power supply, or a heat sink with a connector. The component allows an LED lighting unit to be used without having the power supply and/or a heat sink take up space within what a consumer would normally see as the light bulb. In some embodiments the form factor is that of a screw-in socket such as an Edison E-26 socket. A connector or connectors can allow removal of the power supply portion of the lighting unit, or of the LED and possibly an optical element from the power supply.

Abstract: A method is disclosed for preparing carrier wafers for semiconductor device manufacture. The method includes the steps of sorting a plurality of standard carrier wafer blanks into batches by thickness to define a batch of starting carrier wafers that are within a predetermined tolerance of one another, reducing the thickness of the sorted carrier wafers to within 10 microns of a final target thickness, and polishing the sorted carrier wafers to the final target thickness. The polished carrier wafers are mounted to device precursor wafers having at least one semiconductor epitaxial layer on a substrate by joining one surface of a carrier wafer to the epitaxial layer on a substrate. The thickness of the device precursor wafer is then reduced by removing material from the device precursor substrate opposite the joined epitaxial layer.

The rotor is housed within a chamber containing a field controllable material which is acted upon by a magnetic field generator to impede movement of the rotor. The shaft is supported by bearings. The controllable brake housing defines a second housing chamber adapted to enclose means for monitoring and/or controlling the brake and in this way, an integrated, compact controllable brake is provided.

Abstract: A safety switch is provided to detect when a tube launched which exits the tube. The switch is located within the vehicle having a switch plunger extending to the periphery of the vehicle. The plunger is biased to provide outward pressure against a lever on the exterior of the vehicle. The lever rides within the bore of the launch tube such that, when the vehicle is within the launch tube, the lever contacts the interior bore of the tube. The lever contacting the tube bore prevents the plunger from extending to activate the switch. When the vehicle exits the tube, the lever is free to rotate away from the vehicle allowing the plunger to extend and activate the switch which may be a single or multi-pole switch.

Abstract: A launching mechanism is provided for ejecting a small buoy from a high sd deep depth submersible. The buoy is held in place and constrained by a pair of latch levers that lock into a groove in the buoy tail piece. The latch levers are held in place by locking pins. On launch a solenoid valve is operated allowing ambient sea pressure to actuate a release system. The sea pressure retracts a release piston assembly to which the locking pins are attached. Upon withdrawal of the locking pins, the latch levers are released by the force of neg'ator ejection springs. The ejection springs accelerate an open ended cage containing the buoy through a four foot displacement. The buoy strikes a plunger actuating a muzzle plug release mechanism that permits ejection of the buoy from the launch cage.
