Patent number: 5480032Abstract: A wide variety of product types, sizes and shapes are sorted into designated destination bins or other outputs utilizing a computer controlled transport path that includes an infeed section and a pinch roller diverting section. The infeed section receives a singulated stream of products to be sorted, optically scans each product for a destination code and transports the products downstream to the diverting section. The diverting section consists of a series of individually and selectively controlled roller pairs in combination with a number of diverting gates. Each roller pair includes an upper foam covered pinch roller and a lower friction drive roller oriented such that products moving downstream pass between each roller pair until diverted from the transport path. An array of photoelectric detectors provide product position information to identify and track product movement through the apparatus.Type: GrantFiled: February 9, 1994Date of Patent: January 2, 1996Assignee: ElectroCom Automation, Inc.Inventors: James M.

Patent number: 5465243Abstract: The optical tape recorder of the present invention is capable of archiving data at rates in excess of 400 megabits per second by concurrently writing or reading a plurality data tracks in each data trace. A read-write module outputs an illumination beam comprised of combined multiple write beams (channels), a read beam and an autofocus beam. Optics within the read-write module spatially combine and accurately position the plurality of beams with respect to each other to form the multi-beam illumination beam. A read-write head comprised of a synchronized scanning transmissive polygon and rotating lens wheel scans the multi-beam illumination beam across a recording media to read or write multi-channel data tracks. An autofocus system is also included to ensure that the multi-beam illumination beam is accurately focused on the recording media.Type: GrantFiled: April 25, 1994Date of Patent: November 7, 1995Assignee: E-Systems, Inc.Inventors: John D.

Patent number: 5463404Abstract: A prefabricated and assembled microstrip antenna element has at least one layer of dielectric substrate on which is deposited a metal etched to form a radiating element and over which is attached a protective radome. To compensate for uncontrollable variations in the dielectric constant of the substrate between different lots of material, the resonance frequency of the assembled microstrip is shifted or tuned to a desired resonance frequency by drilling a bore hole of predetermined diameter and location through the radome, metal layer and substrate that removes a predetermined amount of metal from a predetermined location on the radiating element. The bore hole is then filled with a non-conductive epoxy having a dielectric constant approximately equal to that of the substrate.Type: GrantFiled: September 30, 1994Date of Patent: October 31, 1995Assignee: E-Systems, Inc.Inventor: Angela M.

Patent number: 5462357Abstract: A method of estimating both atmospheric conditions and surface temperatures of an object from either a single set of multispectral images or multiple simultaneously-acquired single-band images of the object. Estimates of atmospheric conditions are generated by determining and radiometrically correcting radiance values measured from the image of the object. Expected radiance values are then determined and compared with the measured radiance values. The best fit of the radiance values measured from the image of the object to the expected radiance values corresponds to the best estimate of the atmospheric conditions associated with the object. The present method estimates atmospheric conditions for the object regardless of the availability of atmospheric conditions associated with the image.Type: GrantFiled: October 28, 1993Date of Patent: October 31, 1995Assignee: E-Systems, Inc.Inventors: Paul M. Ingram, Jr., James R. Johnson, Fenton L. Givens

Patent number: 5451771Abstract: A singulated stream of products comprised of both single and overlapping products is transported through a scanning zone along a transport path. Each single or overlapping product defines a shadow on the transport path that is analyzed to determine the presence of product multiples in the product shadow by measuring the width and length of the product shadow. If the length of the product shadow exceeds by more than a predetermined amount the average length of previously measured shadows having a similar width, the shadow likely contains two or more overlapping products. As the product shadow moves through the scanning zone, each product included therein is scanned for affixed bar codes by a plurality of bar code scanners. If two different bar codes or two identical bar codes from mutually exclusive scanners are recorded for a single product shadow, then the shadow likely contains two or more overlapping products.Type: GrantFiled: September 12, 1994Date of Patent: September 19, 1995Assignee: ElectroCom Automation, Inc.Inventor: Gary S. Robertson

Patent number: 5450228Abstract: The present invention provides a read-write head for an optical tape recorder comprised of a synchronized scanning transmissive polygon and rotating lens wheel. The transmissive polygon is a multi-sided piece of transparent optical quality material for displacing a through transmitted collimated read or write light beam. The lens wheel comprises a unitary disk-shaped piece of optical quality material having a plurality of individual lenses precision molded or diamond point turned therein for focusing the through transmitted and displaced read or write light beam onto a recording media. The polygon is rotated to translate the displaced beam for scanning along a linear path aligned with an arcuate path followed each successive lens on the rotating lens wheel.

Patent number: 5450250Abstract: Separations between the end of one data file and the beginning of the next data file are recognized, without utilizing an entire data storage block by means of a controlling program for a peripheral recording device monitoring the control information headers of helically stored data on a recording tape. When files are stored on the recording tape, the controlling program increments an increase of a file section number by one and increments to zero a data block number at the beginning of a new data file. When the recording device is reading the recording tape and there is detected an incrementation of the file section number and a zero value for a data block number, a recognition is made that this data indicates the end of one data file and the beginning of another data file.Type: GrantFiled: February 28, 1992Date of Patent: September 12, 1995Assignees: E-Systems, Inc., Ampex CorporationInventors: Jose A.

Patent number: 5444864Abstract: A method and apparatus system for cancelling a leak-through signal component generated by an interfering transmitter from a received/leak-through signal comprising a multiplier for multiplying the received/leak-through signal by a reference signal provided from the interfering transmitter. The system further includes an integrator for integrating the output of the multiplier to generate an estimate of the gain and phase of the leak-through signal component. A gain and phase adjustor, responsive to the generated gain and phase estimates, is also included for adjusting the gain and phase of the reference signal to generate a cancellation signal that is a substantially gain and phase matched estimate of the leak-through signal. The generated cancellation signal is then subtracted from the received/leak-through signal to substantially cancel the leak-through signal component.Type: GrantFiled: December 22, 1992Date of Patent: August 22, 1995Assignee: E-Systems, Inc.Inventor: Winthrop W.

Patent number: 5437785Abstract: An apparatus for gas entrainment of wastewater in an anaerobic wastewater treatment system, the use of which includes the steps of withdrawing wastewater from an anaerobic digester and piping it into a flotation container. Thereafter the wastewater is pumped into a free standing tank having pressure in the tank maintained at a predetermined level through the injection into the tank of compressed gas generated by anaerobic digestion occurring in the treatment system. The wastewater is removed from the tank and pumped through a multiple jet configuration wherein gas from the tank is entrained in the wastewater as the water is injected back into the tank. The gas entrained water is then discharged from the tank back into the flotation container where the gas bubbles particles to the surface of the water to form a sludge layer.Type: GrantFiled: November 22, 1993Date of Patent: August 1, 1995Assignee: Darling InternationalInventor: Mel Roshanravan
