Title: Sound imaging method and apparatus
Inventor: LOWE DANNY D
IPC: H04S1/00
Filed: 1989-09-01
Granted: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE         The illusion of distinct sound sources distributed throughout the three-dimensional space containing the listener is possible using only conventional stereo playback equipment by processing monaural sound signals prior to playback on two spaced-apart transducers.  A plurality of such processed signals corresponding to different sound source positions may be mixed using conventional techniques without disturbing the positions of the individual images.          Although two loudspeakers are required the sound produced is not conventional stereo, however, each channel of a left/right stereo signal can be separately processed according to the invention and then combined for playback.          The sound processing involves dividing each monaural or single channel signal into two signals and then adjusting the differential phase and amplitude of the two channel signals on a frequency dependent basis in accordance with an empirically derived transfer function that has a specific phase and amplitude adjustment for each predetermined frequency interval over the audio spectrum.  Each transfer function is empirically derived to relate to a different sound source location and by providing a number of different transfer functions and selecting them accordingly the sound source can be made to appear to move.

Abstract: A unitary molded plastic bakery tray, with the end walls higher than the side walls to provide for a 90 degree cross-nesting, and the end walls having interengaging feet and rails to provide for 180 degree oriented high stacking and like oriented low stacking. The bottom is either a flat planar surface with chamfered bottom edges or is raised so that the tray is provided with corner structure having chamfered bottom edges. Blind stacking structure is provided by an additional outer rail on each end wall and additional outer feet on each end wall for engaging the outer rail. Alternatively, blind stacking is provided by structure along each end wall having large feet and cooperating large recesses coplanar with inner small feet and cooperating inner recesses such that the large feet can span and smoothly slide over the small recesses during blind stacking.          Further, trays of different series having different stacking heights can be blind stacked on one another during stacking, but include bottom and side wall structure that prevents inter cross-nesting of trays of different series.

Abstract: METHOD AND TARGET FOR SPUTTER DEPOSITING THIN FILMS       Abstract A sputtering target has a sputtering surface with first and second regions of respective first and second materials. The first region comprises a surface of a first member of the first material, such as of a circular cobalt plate.  The se-cond region comprises a surface of a second member of the se-cond material, such as a platinum ring.  A cobalt cover ring clamps the platinum ring to the cobalt plate.  By varying the relative sizes of the first and second regions, as by changing the size of the cover ring to expose more or less of the platinum ring, the concentration of the two materuals in a layer deposited from the target onto substrates is varied. In addition, by imparting planetary motion to substrates during deposition and sizing and positioning the exposed por-tion of the platinum ring, a radial coercivity gradient is established in the layer deposited on the substrates.

Abstract: Abstract of the Disclosure Signal conversion apparatus transforms an input signal having a value falling in one of a plurality of ranges into an output signal whose value varies for each different range. All of the output signal values corresponding to the plurality of ranges form an ordered set. The output signal values in this set are related to one another such that the value of any output signal is equal to the immediately preceding output signal value multiplied by a predetermined factor which is a constant for at least a plurality of consecutive output signal values. Use of such a relationship between output signal values advantageously reduces quantization errors in certain telecommunications applications and can be embodied within analog-to-digital, digital-to-analog and digital-to-digital signal conversion apparatus.

Abstract: This is an electronic scheme for correcting mechanical misalignment and electrical delays from laser beam to laser beam in the scan direction of a multiple beam laser scanning system for use in an electrophotographic machine.  The position at which a reference beam is turned on is sensed and adjusted to a desired position.  Thereafter, the positions at which non-reference laser beams are turned on are sensed and adjusted to the desired position.  In one embodiment, the energization of laser beams is posi? tioned at the trailing edge of the second element of a photodetector.  In a second embodiment, the point of full laser energy is matched, beam to beam, at the junction of the same two elements in a CCD array.  Programmable delay lines are used to obtain sub-pel resolution.
