摘要： A magnetically actuated visual display board comprises a grid array of open ended chambers. Display configurations in each chamber utilize a magnetically responsive sliding element to move a display loop to alternate between two different display surfaces to create a desired visual array. A magnetic rod passing a chamber moves the sliding element within the chamber.

摘要： An instant no-sew and removable fabric fastener is similar to a spring push-pin fabric fastener, and thus, the instant no-sew and removable fabric fastener includes a fastener socket and a fastener stud. However, the instant no-sew and removable fabric fastener is different than a standard spring push-pin fabric fastener by incorporating a rotational-type attachment mechanism and by being completely removable. The rotational-type attachment mechanism allows the fastener stud and the fastener socket to be deadlocked to each other. The fastener stud cannot be detached from the fastener socket even with a force until either the fastener socket or the fastener stud is rotated 90 degrees. After the fastener socket or the fastener is rotated 90 degrees, the fastener stud can be detached from the fastener socket. Additionally, this means the instant no-sew and removable fabric fastener does not permanently attach to fabric and thus, can be removed when desired.

摘要： A spring tensioned roller and spaced tension bar have a vehicle cover folded in half and rolled around the spring tensioned roller. The rear half of the cover has an end rod and a central opening which allows it to be hooked over a trunk lock mechanism and kept secure when the trunk is shut. The front half of the cover has a lead rope or belt with two hooks for securing it under the hood of the vehicle or any other edged surface on the front of the car. The tensioned cover is elevated above the roof of the vehicle by the roller and tension bar for purposes of ventilation.

摘要： A center foam strip has a series of transverse fold lines separating the strip into panels which fold onto each other in an accordion pattern for storage. A soft fabric waterproof cover material is attached to the center foam strip to hang down the sides of the vehicle to be closed in the vehicle doors shading the side windows. The cover material and center foam strip are sewn together to conform to the shape of the top of a particular vehicle with the foam strip covering the roof, windshield, and rear window. The center foam strip and surrounding soft fabric are held in place by the trunk lid, doors, and windshield wipers.

摘要： A resonant power converter is disclosed with a driving circuit generating a switching signal connecting power to a resonant tank circuit, with a voltage monitoring circuit measuring a voltage output and a load current. A micro-controller is operable with a control circuit for multiple step sampling with the switching signal at a switching frequency to settle the resonant circuit determined from the voltage output and load current. A fast load transient response at a high frequency with the resonant circuit provides the multiple step sampling to ensure enough time for micro-controller to calculate. Optimal trajectory control facilitates a burst mode of high frequency with the resonant circuit using adaptive multiple step sampling for an on-time to extend the burst operation range. A soft start-up process uses the micro-controller processing in multiple stages.

摘要： Systems and methods for applying cosmetics are provided using an incoherent light projector shining light on the face, capturing the reflected light using a camera and the projector, communicating with the camera and the projector and a structured light depth processor to generate a depth image output. A control device communicates with the structure light depth sensor to receive the output, to receive the face profiles and generate motion trajectory commands, and a robot communicates with the control device to receive the commands to apply the cosmetics to the face in accordance with the face profiles. Methods for applying the cosmetics include receiving a face profile, receiving a depth sensor input representing a face, extracting face features, matching the face profile to the face features, and generating a guide or outputting robot trajectory to apply the cosmetics.
