An acoustic otoscope generates volume change excitations of either a trapezoidal or sinusoidal waveforms which are coupled into a sealed ear canal using a speculum tip. The change in volume results in a pressure change, for which a pressure measurement is taken during the volume change excitation interval. In one example, a trapezoidal time-domain volume change is presented, and a pressure measurement waveform is stored, the pressure measurement waveform thereafter examined to find a change of slope point in time, after which the pressure measurement waveform is scaled to be equal to the volume change waveform at that same point in time, a difference between scaled pressure measurement and volume excitation is formed, and examined for peak value prior to the earlier determined change in slope point in time.

According to one example a linear translation stage is provided. The linear stage includes a first portion (e.g., a base portion) and a second portion (e.g., a stage portion) configured for relative translation with respect to each other. One of the first portion or the second portion has a coil associated therewith and the other of the first portion or the second portion has a magnetic source associated therewith. The magnetic source may include one or more magnets to produce a magnetic field that generally encompasses the coil such that current through the coil causes a force on the coil, thereby causing translation of the first portion relative to the second portion.

Tunable external cavity lasers are used in applications such as interferometry, FM spectroscopy, and optical communications equipment testing. Mode hop free high bandwidth frequency modulation operation is desired in a tunable external cavity laser. This application describes new and novel techniques for controlling the output wavelength of a tunable external cavity laser while suppressing mode hop.

The present invention provides a temperature controlled energy transparent window or electrode used to advantage in a substrate processing system. The invention also provides methods associated with controlling lid temperature during processing and for controlling etching processes. In a preferred embodiment the invention provides a fluid supply system for the lid which allows the fluid to flow through a feedthrough and into and out of a channel formed in the window or electrode. The fluid supply system may also mount the window or electrode to a retaining ring which secures the window or electrode to the chamber. In another aspect the invention provides a bonded window or electrode having a first and second plate having a channel formed in the plates so that when the plates are bonded together they form a channel therein through which a temperature controlling fluid can be flowed. An external control system preferably regulates the temperature of the fluid.

A method for electrohydrodynamic printing wherein multiple colors are printed by discharging the receiving medium by reverse-sign corona discharge, then charging the receiving medium by corona discharge, and then printing the first color. The receiving medium is then discharged, and charged a second time by corona discharge. The process is repeated for each color used in the printing. As a result, the colors are printed in their intended locations without deflection even if the intended location is a dot of previously deposited color.
