Latest Patents

One of his latest inventions is the acoustic otoscope. This device generates volume change excitations of either 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 is then examined to find a change of slope point in time. After this, the pressure measurement waveform is scaled to be equal to the volume change waveform at that same point in time. A difference between the scaled pressure measurement and volume excitation is formed and examined for peak value prior to the earlier determined change in slope point in time.

Another significant patent is a linear stage that includes an integrated actuator and associated methods. According to one example, this linear translation stage consists of a first portion, such as a base portion, and a second portion, such as a stage portion, configured for relative translation with respect to each other. One of these portions has a coil associated with it, while the other has a magnetic source. The magnetic source may include one or more magnets to produce a magnetic field that generally encompasses the coil. This setup allows current through the coil to create a force, causing translation of the first portion relative to the second portion.
