Abstract: A lever assembly and hair clipper with a lever assembly is provided. The lever assembly may include a shaft having a plurality of dimples arranged around a periphery thereof, a pin with an apex, the apex being shaped to mate with the dimples of the shaft, and a spring mounted on the pin. Moreover, the device may include a lever having a head section and an arm section; the head section of the lever including a cam protrusion, and a first cavity shaped to receive the shaft and defining an axis of rotation of the lever; and the arm section including a cavity that receives the pin and the spring, and aligns the apex of the pin with the dimples of the shaft.

Abstract: An image-based camera calibration system includes a calibration processor configured to calibrate image frames of a video feed. The calibration processor determines a proposed calibration of the image frame to initialize a refined calibration process that generates a refined calibration. The refined calibration may be generated by rendering a 3D model of the environment captured in the video feed and comparing the rendering to the video feed image and adjusting the proposed calibration values such that the comparison between the rendered image and the image frame is minimized. The system is configured to generate the calibration for sequential images of the video feed in real-time to support live broadcasts without the need for additional data with respect to the camera position, only the video feed.

Abstract: A modular tracheostomy task trainer device comprising a base unit comprising at least one attachment point, and at least one module comprising an attachment point configured to removably attach to the at least one attachment point of the base unit. A tracheostomy training kit comprising the modular tracheostomy task trainer device.

Abstract: A system and method are described that include pre-processing of user data at a mobile communication device prior to transmission of the user data to a cellular-connected server. Such pre-processing increases the efficiency of the cellular-connected server to permit near real time mapping of dead zones while maintaining a high degree of accuracy of the dead zone boundary.

Abstract: A shredded cheese product blend and a method of making such a shredded cheese product blend is disclosed in which the blend is a mixture of one or more types of shredded cheese and one or more kinds of vegetable and/or fruit particles, and optionally also includes one or more spices. One or more shredded cheeses are blended with one or more vegetable and/or fruit particles having reduced moisture content in selected relative amounts, with the shredded cheese product blend then being packaged in a conventional manner. A variety of different cheeses can be shredded, or a blend of two or more cheeses can be shredded and mixed together. A number of different vegetables and/or fruits can be used, and combinations of two or more vegetables and/or fruits can be particularized and mixed together.
