  • Patent number: 11974845
    Abstract: Systems and methods are disclosed which provide for a “factory-calibrated” sensor. In doing so, the systems and methods include predictive prospective modeling of sensor behavior, and also include predictive modeling of physiology. With these two correction factors, a consistent determination of sensitivity can be achieved, thus achieving factory calibration.

  • Patent number: 6413083
    Abstract: A computerized system and method for diagnosing a tooth-size discrepancy and recommending an ideal arch size based on the size of an individual patient's teeth. The computerized system includes a central processing unit, a first storage device, a second storage device, a dynamic memory device, and input/output devices. The input devices include a computerized caliper for measuring the mesiodistal width of teeth and directly inputting the measurements into the computerized system. The computerized system and method determine the existence of a tooth-size discrepancy, the necessary anatomical correction, at least one tooth responsible for the tooth-size discrepancy, and a recommended arch wire size.

  • Patent number: 6280184
    Abstract: An orthodontic onlay having a mesial and distal sections is debonded from multiple teeth by positioning a plier-type debonding apparatus having a first and a second lever arms pivotally connected for rotation relative to each other and having respectively a first and a second handle portions, a hook extending from said second jaw portion, and a bracing platform pivotally connected to said first jaw portion and facing the hook. The appliance is removed by engaging the hook at the adhesive line of the appliance and the tooth, placing the bracing platform against the occlusal bonded surface of the appliance, pivoting the debonding apparatus clockwise and counterclockwise.

  • Patent number: 6153864
    Abstract: A cap sealing unit for securing foil-polymer laminate innerseals to containers has an air cooled electronics cabinet that may be sealed in accordance with NEMA 4 standards. Heat sinks in the bottom of the electronics cabinet and the top of the sealing head are cooled by two external, wash-down safe fans disposed between the cabinet and the sealing head. The fans draw air in opposite directions, one toward the cabinet and the other toward the sealing head. The cap sealer can be operated with interchangeable flat or tunnel sealing heads of various sizes and coil windings that can be connected to the power supply with plug-in shielded connector assemblies.

  • Patent number: 5100255
    Abstract: An apparatus for joining lengths of tubing to form tooling structures for high temperature and high pressure molding processes. The apparatus is shaped to join lengths of tubing in the configuration of the tooling structure, contact the joined lengths of tubing on at least one side, and enclose on three sides the joined lengths of tubing.

  • Patent number: 4639740
    Abstract: A method and apparatus for laser marking of an article in which a pulsed, linearly polarized laser beam is passed through a stencil-type mask and imaged onto an article to be marked.In order to increase the overall transmission and hence the efficiency of the process, at least part of the laser beam energy which is reflected from the opaque parts of the mask is collected and redirected to the mask. The apparatus includes means for separating by beam polarization that portion of the laser radiation reflected by the opaque parts of the stencil and means for reflecting said portion of the radiation back to the stencil.

    Assignee: Laser Applications Limited
    Inventor: David C. Hamilton
  • Patent number: 4340969
    Abstract: Laser apparatus operable in the range 8 to 50 microns, has an optical cavity defined by two mirrors M1 and M2, one of which is partially transmitting. The cavity contains a laser active medium AM and a reflecting polarizer RP. The reflecting polarizer comprises a substrate carrying a metallic reflecting coating covered by a dielectric layer of alumina, silicon dioxide or magnesium oxide. The wavelength of operation determines the dielectric material to be used, and the thickness of the layer determines the absorption loss introduced into one of two perpendicular planes of polarization.

  • Patent number: 4193444
    Abstract: The present invention constitutes an electrical mounting and conduction means having a support element having a generally U-shaped interior surface, the base of the exterior of the support element being in thermal contact with a heat dissipating surface; a carrier element having a generally U-shaped exteriorsurface, the surface having a cross-section of smaller dimension than that of the U-shaped surface of the support element, the carrier element being nestable within the support element; and locking means removably securable to adjacent arm members of each of the support and carrier elements for maintaining the support and carrier elements in selective securement to each other.
