The device tethering system may include a retraction component, tether, pouch, belt, device mounting component, device aspect of the device mounting component, and/or tether aspect of the device mounting component. A method for securing a device to a source location using the device tethering system is also provided.
Abstract:
An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body is made from a transparent or translucent polycrystalline ceramic for improved aesthetics. The movable member may comprise the polycrystalline ceramic. The polycrystalline ceramic has a grain size distribution characterized by an average grain size in the range of larger than 3.4 μm to about 6 μm. The polycrystalline ceramic may have a fracture toughness of at least 4.0 MPa·m1/2. The grain size distribution may not be characterized as a lognormal distribution and may be a multimodal distribution. The polycrystalline ceramic may comprise aluminum oxide or alumina. The grain size distribution may be characterized by having up to about 50% of the grains being less than about 3 μm in size. The grain size distribution may be characterized by having up to about 90% of the grains being less than about 10 μm in size.
Abstract:
An improved assay of target components in a sample utilizes specific gravity-altering particles which are attached to the target components by specific antibodies. The attached specific gravity-altering particles are preferably liposomes which will buoy or sink the targets to a common level in the specimen sample when the latter has been centrifuged in a transparent tube. The liposomes can provide an accentuated and more pronounced indication of the presence of the targets in the sample due to their ability to contain many multiples of fluorescent or non-fluorescent dye molecules with minimal steric interference with the attached antibodies' binding ability.
Abstract:
A food cooking oven having exterior walls and inwardly spaced interior walls wherein the interior walls are electrically conductive and are connected to an electrical power source. In operation, the interior of the oven is heated to a food cooking temperature by passing an electric current through the interior walls of the oven.
Abstract:
An outboard motor unit for use on small boats and having a primary propulsion engine connected through a clutch to the propeller shaft and an electric motor aligned with and connected to the propeller shaft. The electric motor is connected to a battery through a switch operatively connected to the engine throttle to complete the power connection for the electric motor when the throttle is at a selected proportion of full throttle. The electric motor operates as a motor when the engine is stopped and as a generator when the engine is running.
Abstract:
A sample cartridge (40) for microscopic imaging of a biological sample comprises a body having an end portion (43) and a pair of generally parallel opposing side edge portions (44), a locking edge portion (45) formed on the body; a carrier removably connected to or permanently connected to the body; and at least one anti-analyte antibody coupled to either the carrier or to the chamber (41) side wall portion (e.g., at the surface to be imaged, or supporting the sample to be imaged). An XYZ stage (101) for receiving such a cartridge (40) is also described.
Abstract:
Embodiments include strain sensor devices for detecting movement, morphological changes or other physical parameters within a patient's body tissue. Some embodiments are directed specifically to measuring parameters within a patient's heart and may also be configured to communicate with an implantable stimulation device and associated external programming device.
Abstract:
A high pressure xenon arc illuminator bulb having a sapphire window generates a broad band of ultraviolet, visible and infrared radiation extending from about 180 nanometers to about 2000 nanometers.The emitted radiation in the range from about 180 to about 200 nanometers, in passing through the oxygen in the air, causes the molecules of oxygen in the form O.sub.2 to recombine to produce ozone, O.sub.3. Ozone is toxic.In the invention, a lens barrel, which holds a sapphire condensing lens, is joined to the xenon arc illuminator bulb with a lighttight and also hermetic connection. Thus, the condensing lens is optically rigid with the illuminator bulb and the ozone formed within the lens barrel is not released to the ambient environment, even though its local concentration within the lens barrel becomes high. Furthermore, the ozone confined within the lens barrel acts as an absorption filter for all of the wavelengths in the 180 to 200 nanometer band which are capable of producing ozone.The ultraviolet and other radiation leaving the sapphire condensing lens therefore does not produce toxic ozone in the ambient environment.
