    摘要: A device for measuring the absolute value of the refractive index of a liquid by immersion uses the optical properties of a cylindrical waveguide with a solid core and normal angle of incidence of the light source. The device consists of a transparent tube forming the enclosure of the waveguide, impervious to the surrounding liquid and partially filled with a transparent solid or liquid material of appropriate index of refraction, a fiber optic means of inputting light via a LED or laser and fiber optic means of coupling emerging light to a photodetector. The emerging light intensity is a function of the index of refraction of the surrounding liquid.

    摘要: A videoconference device provides an interface for initiating and controlling a videoconference and incorporating and annotating content in the videoconference without a personal computer. The content may reside on a portable storage medium such as a Universal Serial Bus (USB) or other flash memory device inserted in the interface device or on the device itself. The interface device may be a dedicated device for controlling the videoconferencing system, navigating to desired content, and interacting with the shared content. The device may also be a portable device such as a tablet device or mobile phone that interfaces with a videoconference system via an installed application.

    摘要: Electronics packages are provided with structure that provides a significantly-reduced package footprint and also facilitates substantial reduction of package fabrication time and cost. The footprint reduction is realized with a frame that defines an aperture wall which surrounds first sets of components on the first side of a printed circuit board and also extends away from the printed circuit board to provide package input/output access along the perimeter of the package footprint. The second side of the printed circuit board receives a second set of components and this set is protected by a board fill. The frame and printed circuit board are configured for realization from frame and board panels whose planar forms substantially reduce package fabrication time and cost because they facilitate the use of modern high-speed printed circuit board (PCB) fabrication processes.

    摘要: Systems for removing a tire from a rim are shown and described. In one embodiment, the system comprises a substantially flat base. A centerpiece is configured to attach to the base. A primary lever having a tire-interface portion at one end, a handle at the opposite end, and a centerpiece-attachment in between the tire-interface the said handle is also a component of the system. The primary lever is configured to attach to the centerpiece in a manner that allows the primary lever to rotate relative to the centerpiece.
