  • Video traffic monitor for retail establishments and the like
    Patent number: 5465115
    Abstract: A video traffic monitor and method for counting people using video imaging provides an inexpensive hardware implementation for analyzing real-time video where the operational environment presents a reasonably restricted traffic flow, such as in the entryway of a building. The video traffic monitor utilizes a windowed subsample of an image frame, and the image frame is further subdivided into gates. The video traffic monitor processes this windowed area to highlight the objects moving through the gates. The gates are then analyzed to determine a direction of movement for the people and support the logic for noise elimination and object discrimination. The video traffic monitor counts the detected people and records the count according to the direction of movement of the people.

  • Method and apparatus for determining driver fitness in real time
    Patent number: 5465079
    Abstract: A method and apparatus for evaluating a driver's performance under actual real-time conditions and for using such evaluations to determine the driver's ability to safely operate a vehicle compares the information gathered by a radar system and other sensors with information previously stored in an event recording device. Conditions monitored are used to make a determination as to whether the driver is performing in conformity with normal driving standards and the driver's own past performance. The driver's performance is constantly monitored and compared to that driver's past performance to determine whether the driver's present performance is impaired, and if so, whether the impairment is detrimental to the driver's ability to safely operate the vehicle.

  • Two-stage water gas shift conversion method
    Patent number: 5464606
    Abstract: A method and apparatus are provided for reducing the concentration of carbon monoxide in a gaseous reactant stream comprising carbon monoxide and water vapor. The catalyst bed of a water gas shift reactor is preferably divided into two sections. Alternatively, an assembly which includes two sequential reactors can be employed. The first section or reactor operates in an adiabatic fashion whereas the second section or reactor is cooled, thereby facilitating the further conversion of carbon monoxide in the second section or reactor. The gaseous reactant stream exiting the second section or reactor typically has a carbon monoxide concentration in the range from about 0.06% to about 0.14% by volume.

  • Method for coplanarity inspection of package or substrate warpage for ball grid arrays, column arrays, and similar structures
    Patent number: 5465152
    Abstract: A method for determining coplanarity with 3-D sensing means of substrates for ball grid array, column grid array, and similar surface mount integrated circuit chips, in which opaque fiducials are provided as index pads. Heights of the index pads are correlated with signal pad heights in a neighborhood about the index pads. The index pads are opaque to incident radiation from the 3-D sensor. The index pads reflect sufficient radiation to be detected easily by the 3-D sensor. The index pads are disposed in a prearranged pattern over a domain of ball grid array signal pads. The index pads are restricted to a predetermined range of heights.

  • Cellular based traffic sensor system
    Patent number: 5465289
    Abstract: A method and apparatus for providing vehicular traffic information using presently existing cellular telephone system technology. Traffic sensors monitor the control and voice channel transmissions of cellular units within a cellular telephone system. Data from these transmissions is extracted and analyzed according to a statistical model and derived vehicle geolocating information to generate vehicular traffic information that is transmitted to a central control center. By combining the information from all of the traffic sensors and each individual cell within a cellular telephone system, a picture of the traffic conditions existing along major thoroughfares may be determined.

  • Optical recorder and reader of data on light sensitive media
    Patent number: 5465243
    Abstract: 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.

  • Cardiac ablation catheters and method
    Patent number: 5464404
    Abstract: A catheter uses a steerable outer catheter with an inner catheter rotatable and extendable with respect to the outer catheter. The outer catheter may be positioned within a patient's heart and a portion of the outer catheter may provide movement like that of a windshield wiper by manipulation of a spring. By combining the windshield wiper type movement with the extension and rotation of the inner catheter relative to the outer catheter, a large area within a patient's heart may be readily mapped for conduction tissue and be subjected to laser ablation if appropriate. Various configurations provide flexibility in relatively positioning of windows used to apply laser energy and ring electrodes used to sense conduction tissue.

  • Method and apparatus for timing acquisition of partial response class IV signaling
    Patent number: 5465059
    Abstract: A method and apparatus for timing acquisition of partial response class IV Signaling is described. The invention uses an acquisition logic block to determine an output sequence that best matches a preamble pattern. The logic block analyzes current quantizer output X and the two previous decisions X.sub.n and X.sub.n-1. The logic uses these values to determine the next value X.sub.n+1 so that the best match occurs. The invention is implemented with OR gates, AND gates, and D flip-flops and can operate in acquiring mode or tracking mode.

  • Process and apparatus for the treatment of semiconductor wafers in a fluid
    Patent number: 5464480
    Abstract: Provided is a process for removing organic materials from semiconductor wafers. The process involves the use of subambient deionized water with ozone absorbed into the water. The ozonated water flows over the wafers and the ozone oxidizes the organic materials from the wafers to insoluble gases. The ozonated water may be prepared in-situ by diffusing ozone into a tank containing wafers and subambient deionized water. Also provided is a tank for the treatment of semiconductor wafers with a fluid and a gas diffuser for diffusion of gases directly into fluids in a wafer treatment tank.
