International Classification:

H03F 3/191

US Classification:

330302, 330305

Abstract:

A circuit having: an input matching network; a transistor coupled to an output of the input matching network; and wherein the input matching network has a first input impedance when such input matching network is fed with an input signal having a relatively low power level and wherein the input matching network has an input impedance different from the first input impedance when such input matching network is fed with an input signal having a relatively high power level.

International Classification:

B05B 5035

US Classification:

427 30

Abstract:

An electrostatic coating method and apparatus are provided that are capable of applying an extremely thin and virtually constant thickness coating to a substrate, and includes a coating applicator having an opening formed of dielectric material through which coating material flows for coating purposes. The coating material supplied to the applicator is pressurized to maintain a substantially constant volume of coating material at the applicator opening output and is vibrated in the vicinity of the applicator opening to provide a uniform flow of coating material to the applicator output, to stabilize the shape of the coating material at the applicator output and to preclude changes in coating material flow rate caused by electrostatic field induced coating material dryout. An electrostatic field of predetemined magnitude is established between the coating material surface and the adjacent substrate to thereby extract minute, uniform size particles from coating material at the applicator opening and subsequently deposit an ultra-thin layer of these particles on the adjacent substrate as the substrate moves past the applicator opening. In dielectric substrate coating applications where a relatively thick coating layer is required, an electrostatic charge is established on the dielectric substrate, at a remote location, before the substrate is coated in order to neutralize the electrostatically charged coating material so that such coatings can be electrostatically applied.

G06K 9/00

Abstract:

Augmented reality-based training and troubleshooting is described for medical devices. An electronic mobile device can be equipped with an AR application that, when executed, causes the electronic mobile device to provide augmented reality-based training on how to set up, or perform maintenance on, one or more components of a medical device. The AR application, when executed, can also cause the electronic mobile device to provide augmented reality-based troubleshooting for one or more components of a medical device.

US Classification:

330296, 323315

Abstract:

A current mirror circuit having formed in a semiconductor: a pair of transistors arranged to produce an output current through an output one of the transistors proportional to a reference current fed to an input one of the pair of transistors; a resistor comprising a pair of spaced electrodes in ohmic contact with the semiconductor, one of such pair of electrodes of the resistor being coupled to the input one of the pair of transistors; and circuitry for producing a voltage across the pair of electrodes of the resistor, such circuitry placing the resistor into saturation producing current through a region in the semiconductor between the pair of spaced ohmic contacts, such produced current being fed to the input one of the transistors as the reference current for the current mirror.
