Patent number: 7184556Abstract: A sound compensation system alters an electrical audio signal for input to a sonic reproduction device having associated behavioral characteristics. The behavior characteristics of the device are defined by individual or groups of individual components of the sonic reproduction device and include mechanical, acoustic and electromagnetic behaviors. The model includes a plurality of filters that simulate at least one of the behavior characteristics of the sonic reproduction device. The filters are defined by digital signal processes or by analog circuits and are characterized by one or more of an associated frequency, time, phase and transient response. These responses combine to define an overall response for the model. The filters include adjustable parameters which are used to alter filter responses to produce responses that are conjugates to the responses of the unaltered filters and thus the sonic reproduction device. A controller modifies the parameters.Type: GrantFiled: August 11, 2000Date of Patent: February 27, 2007Assignee: Microsoft CorporationInventors: Keith O. Johnson, Alex Limberis, Mats Myrberg, Timothy E. Onders

Patent number: 5014713Abstract: A body fat thickness measuring device comprising a pair of infrared emitting diodes, one emitting a steady, low-intensity light, and the other emitting periodic, high-intensity pulses of light, to be placed against the skin where the fat is to be measured. The device contains an array of detectors in the form of infrared-sensitive photo-transistors which are placed against the skin in predetermined locations near the two diodes, yet shielded from ambient light. The detector array provides signals proportional to the amount of infrared light detected, and these signals are summed and amplified, forming a composite signal. The amplitude of this composite signal, which is indicative of the thickness of the layer of fat, is displayed on a digital readout device.Type: GrantFiled: December 5, 1989Date of Patent: May 14, 1991Assignee: Tarris Enterprises, Inc.Inventors: Alan Roper, Keith O.

Patent number: 4124784Abstract: A system for detecting and reproducing variable-area-type optically recorded audio signals by cyclically detecting substantially only the position of a boundary of the sound track. In one embodiment, the boundary is detected by imaging the boundary onto an array of photosensors and scanning the array to provide an output signal containing a transition corresponding in the time domain to the position of the boundary. The transition signal is filtered and sliced to provide electrical interpolation to improve the resolution substantially over the special resolution of the photosensitive elements of the array. The system may also include a multitrack capability with means for minimizing the effect of film weave.Type: GrantFiled: May 23, 1977Date of Patent: November 7, 1978Assignee: DBX, Inc.Inventors: Keith O.

Patent number: 3967382Abstract: A system for the measurement of the length of the plenum chamber in a nuclear fuel rod, both before and after service in the nuclear reactor. The system basically comprises inserting the fuel rod into a casing having an eddy current sensing coil therein and advancing it until the coil output provides a signal indicative of the end of the plenum spring being centrally located within the coil. At an end of the casing is provided a plenum chamber length transducer of the displacement type, such as a linear variable differential transformer, which contacts the adjacent end cap of the fuel rod and when the coil provides an appropriate readout corresponding to proper location of the plenum spring end produces an output signal which is indicative of the length of the plenum chamber.Type: GrantFiled: January 10, 1975Date of Patent: July 6, 1976Assignee: Exxon Nuclear Company, Inc.Inventors: Keith O.
