Patent number: 5775033Abstract: The present invention provides a building structure within which a setting is maintained which allows restaurant patrons to enjoy dining out while allowing primarily children accompanying adult patrons the opportunity of playing in an adjacent amusement area without disturbing the adult patrons. The adult patrons, however, can view the children and any other amusement area patrons, allowing monitoring of the children's activity while simultaneously enjoying the view of the children at play and enjoying their meal. Preferably sound proofing is disposed between the two areas. Additionally, other areas, such as an exercise area, a play area, a coffee shop, gift shop, art projection area and the like can be contained within the building structure.Type: GrantFiled: August 20, 1996Date of Patent: July 7, 1998Assignee: Kenquest, Inc.Inventor: Paula Kent Meehan

Patent number: 4661853Abstract: A motion detector for determining image motion in a video signal develops an array of signals representing the difference between pixels from adjacent frames. The array of signals are grouped into subarrays, each of which include the signal corresponding to the pixel under examination for motion. Each of the subarrays are independently examined to determine if the magnitude of all of the pixel differences represented in a particular subarray exceed a predetermined threshold and/or the pixel differences have like polarity. If these conditions are met in any one of the subarrays, a motion signal is produced.Type: GrantFiled: November 1, 1985Date of Patent: April 28, 1987Assignee: RCA CorporationInventors: Barbara J. Roeder, Leopold A. Harwood, Hermann J. Weckenbrock

Patent number: 4654717Abstract: Arc-over in the cathode ray tube of a digital television receiver produces a large current pulse which, when it discharges via the chassis ground, disrupts the reference ground potentials of other circuitry coupled to the chassis ground. The affected circuitry includes digital data storage elements which may experience random state changes caused by the fluctuating ground potential. The CRT arc-over condition is detected by circuitry which applies a pulse to the reset terminal of the microprocessor, causing it to restore the potentially corrupted data in the data storage elements using preset data stored in a less volatile programmable read only memory.Type: GrantFiled: May 20, 1985Date of Patent: March 31, 1987Assignee: RCA CorporationInventor: John W. Stoughton

Patent number: 4654711Abstract: A contour map signal generator is provided for generating television signal. The contour map signal generator consists of n-series connected circuit, each generating signals for a first pattern and second pattern enlarged or reduced from the first and outputting by arithmetic addition contour map data representative of a step region consisting of two patterns. n-step contour map data generated through the n-series circuit is stored in an image memory and read out to be fed back to the input of said contour map signal generator. n x N-step contour map is generated through N times feedback operations. The contour map data is used for generating a television signal representative of a picture effect in which the original pattern area is enlarged or reduced as the time elapses for highlighting the original pattern.Type: GrantFiled: September 5, 1985Date of Patent: March 31, 1987Assignee: Nippon Television Industry CorporationInventor: Tsuneo Mikado

Patent number: 4623924Abstract: A peaking circuit for use in a digital video signal processing system includes a digital peak detector which produces a peak magnitude whenever the slope of the video signal changes polarity. The peak magnitudes, and the absences of peaks are summed in an accumulator over a field period. The accumulated peaks are applied to a gain calculating circuit which develops a peaking control signal having three regimes. For low valued accumulated peaks the gain or peaking control signal is constant and relatively large. For high valued accumulated peaks the gain is constant and negative. In between the gain is in inverse porportion to the value of the accumulated peaks.Type: GrantFiled: February 19, 1985Date of Patent: November 18, 1986Assignee: RCA CorporationInventors: Robert A.
