Abstract: A method and apparatus for quantitatively characterizing performance of a laser steering galvanometer mirror directs a laser beam from a calibration “sensor” onto a side region of the mirror to directly determine rotational positioning, velocity, and/or acceleration thereof using interferometry, time-of-flight measurements, and Doppler measurements. Measured positioning errors can be compared with a database to predict required calibration adjustments. Embodiments automatically adjust digital calibrations. Mirrors, splitters, and/or a plurality of sensors can apply measurement beams simultaneously or sequentially to both sides of a mirror, and/or to more than one mirror. Large rotation ranges, for example larger than +/?15 degrees, can be accommodated by applying measurement beams from a plurality of directions. The calibration apparatus can be distinct, or integral with the galvanometer, and can be used to monitor and/or to control the mirror positioning.

Abstract: A soap reforming assembly includes a housing and a soap collection unit that is coupled to the housing for collecting and transporting pieces of soap when the pieces of soap are dropped into the housing. A heating element is coupled to the housing and the heating element heats the soap collection unit to melt the soap pieces into a fluid soap. A forming unit is positioned within the housing for receiving the fluid soap from the soap collection unit when the heating element produces the fluid soap. The forming unit cools and forms the fluid soap into a bar for bathing. A drawer is slidably positioned in the housing and the drawer receives the bar of soap from the forming unit. The drawer is positionable in an open position having the drawer extending outwardly from the housing to dispense the bar of soap.

Abstract: Mechanical vibration may be sensed by a remotely located ultrasonic sensor. An ultrasonic wave may be transmitted from a transmitter to a vibrating surface, in which the transmitter is separated from the vibrating surface by a distance. A reflected portion of the ultrasonic wave that is reflected from the vibrating surface may be received by a receiver that is also separated from the vibrating surface by a distance. A measure of phase shift amplitude in the reflected portion of the ultrasonic wave may be determined and converted into an amplitude of a vibration of the vibrating surface.

Abstract: A method for correcting long-term phase drift of a crystal oscillator in a numerically-controlled oscillator is described. The method includes determining the phase error in an oscillator signal in comparison with an external time base; delta-sigma modulating the phase error to generate a delta-sigma error bitstream; conditionally adding or subtracting an error correction step size from a phase increment value in each clock cycle based on the delta-sigma error bitstream, to create a modulated phase increment value; and adding the modulated phase increment value to a phase accumulator to generate an error-corrected output digital signal. The delta-sigma-based error correction method avoids the use of multipliers. The same delta-sigma error signal can be used in multiple numerically-controlled oscillators configured to different output frequency if driven by the same reference oscillator.
