    摘要： A method for sharpening a metal carbide emitter tip is disclosed. The metal carbide emitter tip is exposed to an oxygen rich, low vacuum environment when the metal carbide emitter tip is at a first temperature. The metal carbide emitter tip is rapidly heated to a higher second temperature at regular intervals of time.

    摘要： A method for controlling chemical dry etching to improve smoothness of an etched surface is disclosed. Ions are implanted into a surface to form a volatilizable compound at a temperature low enough to avoid, reduce, or eliminate formation of three-dimensional structures of the volatilizable compound that might create the roughness at an etched surface of the volatilizable compound. The ions are applied in a sufficient energy to penetrate to a predetermined depth of material that is to be removed from the surface in an etching cycle, and in a sufficient dosage to achieve full formation of the volatilizable compound. The surface of the volatilizable compound is exposed to a gas composition for a time duration sufficient to completely etch the volatilizable compound.

    摘要： Monitoring a state of a rechargeable battery involves repeatedly obtaining at least one measured value related to the battery during discharge of the battery; repeatedly calculating the state of the battery during discharge of the battery based on a previously calculated state of the battery, the measured value and at least one parameter of the battery; before the state of the battery passes a threshold value, updating the parameter of the battery at a first rate; after the state of the battery passes the threshold value, updating the parameter of the battery at a second rate, faster than the first rate; and correcting the state of the battery in response to each update of the parameter.

    摘要： A method and imaging assembly (10) are disclosed adapted for reading a target object comprising a scan engine (48) having a sensor (46), focusing optics (44), and an imager (48). The scan engine includes a field-of-view defining an area to be imaged by the imaging assembly (10). A housing (80) internally lodges the scan engine (48) and an illumination source (36). The illumination source (36) is adapted to project illumination from the housing (80). A boot (30) extends from the housing (80) for shaping the illumination as it passes through the boot to form an illumination pattern from the illumination. The illumination pattern substantially conforms to a geometrical shape of the boot (30) and is adapted to envelope the scan engine field-of-view.

    摘要： A TE011 cavity filter assembly is disclosed. The system includes at least one resonator operating in TE011 mode having a resonant frequency. The at least one resonator may include a cavity comprising an inner diameter and a cavity length. The at least one resonator may also include a first metal disc inside the cavity. The first metal disc may include a disc diameter and a void in the metal disc, which includes a void diameter and a void depth. The inner diameter of the cavity may be greater than the disc diameter creating a gap with a gap width and a gap depth. The TE011 cavity filter assembly may further include positive coupling.
