  • Publication number: 20200162290
    Abstract: A method and apparatus to adjust a differential transmitter output impedance is disclosed. Output voltage is sampled and averaged to mitigate noise and leakage. Averaged uplevel and downlevel voltages are used to select a number of pullup devices and a number of pulldown devices to control the differential transmitter output impedance to match a distal termination resistance or a transmission line impedance.

  • Publication number: 20200041230
    Abstract: A method of making and deploying a bullet proof vest that can be used to protect students at points of education. The method involves a process of combining/bonding fifteen fiberglass sheets with fiberglass resin in a time specific manner and then pressing the fiberglass sheets together thereby forming a fiberglass plate. A pair of fiberglass plates formed using the present method are thereafter inserted within a vest that has a front and a back receiving pocket. The vest has a strap that is used to tighten the vest on a user wearing the vest. The bullet proof vest of the present invention is inexpensive, lightweight and may also include a tracking device that will inform the authorities of the deployment of the vest. The tracking device of the bullet proof vest will connect to a central monitoring system and will be stored/deployed within an educational desk.

  • Publication number: 20200008899
    Abstract: A stereoscopic camera with fluorescence visualization is disclosed. An example stereoscopic camera includes a visible light source, a near-ultraviolet light source, and a near-ultraviolet light source. The stereoscopic camera also includes a light filter assembly having left and right filter magazines positioned respectively along left and right optical paths and configured to selectively enable certain wavelengths of light to pass through. Each of the left and right filter magazines includes an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter. A controller of the camera is configured to provide for a visible light mode, an indocyanine green (“ICG”) fluorescence mode, and a 5-aminolevulinic acid (“ALA”) fluorescence mode by synchronizing the activation of the light sources with the selection of the filters. A processor of the camera combines image data from the different modes to enable fluorescence emission light to be superimposed on visible light stereoscopic images.

  • Publication number: 20190327394
    Abstract: A robotic imaging apparatus is disclosed. A robotic imaging apparatus includes a robotic arm, a stereoscopic camera, and a sensor positioned between the robotic arm and the stereoscopic camera. The sensor transmits output data that is indicative of translational and rotational force imparted on the stereoscopic camera by an operator. The robotic imaging apparatus also includes a processor that is configured to determine a movement sequence for the robotic arm based on a current position of the robotic arm and the output data from the sensor and to cause at least one of the joints of the robotic arm to rotate based on the determined movement sequence via one or more motor control signals provided to the at least one joint. The rotation of the at least one joint provides power-assisted movement of the robotic arm based on the detected translational and rotational forces imparted by the operator.

  • Publication number: 20190274776
    Abstract: A stereoscopic visualization camera and platform are disclosed. An example stereoscopic visualization camera includes a main objective assembly and left and right lens sets defining respective parallel left and right optical paths from light that is received from the main objective assembly of a target surgical site. Each of the left and right lens sets includes a front lens, first and second zoom lenses configured to be movable along the optical path, and a lens barrel configured to receive the light from the second zoom lens. The example stereoscopic visualization camera also includes left and right image sensors configured to convert the light after passing through the lens barrel into image data that is indicative of the received light. The example stereoscopic visualization camera further includes a processor configured to convert the image data into stereoscopic video signals or video data for display on a display monitor.

  • Patent number: 10299880
    Abstract: A stereoscopic visualization camera and platform are disclosed. An example stereoscopic visualization camera includes a first plurality of lenses positioned along a first optical path and a first image sensor to record a first image stream of a target site from light in the first optical path. The stereoscopic visualization camera also includes a second plurality of lenses positioned along a second optical path, parallel to the first optical path, and a second image sensor to record a second image stream of the target site from light in the second optical path. The stereoscopic visualization camera also includes a processor configured to reduce spurious parallax between the first and second images streams by selecting pixel sets of pixel grids of the first and second image sensors such that zoom repeat points (“ZRP”) are located at a center of the respective pixel grids.

  • Patent number: 6626907
    Abstract: An anterior cervical plate is disclosed, along with threaded fasteners for securing the plate to vertebrae or other osseous material. The cervical plate has several pockets or apertures, preferably at least four, to receive a corresponding number of the fasteners. The pockets have spherical surfaces, and the fasteners have heads with similarly sized spherical surfaces, which when engaged permit each of the fasteners to be oriented at a variety of projection angles with respect to the plate. In connection with each pocket, the cervical plate incorporates a fastener retaining feature. The feature can take the form of a cantilevered tab or a beam supported at its opposite ends, in each case plastically deformable between an open position for admitting the fastener and a closed position for preventing retraction.
