US Patent:

20050051950, Mar 10, 2005

Filed:

May 13, 2002

Appl. No.:

10/144303

Inventors:

David Greene - Baltimore MD, US

International Classification:

A63F007/00

US Classification:

27311800R

Abstract:

Marble Tag is a lively and highly interactive game played in, on, and above a board or maze with marbles guided by sticks. The game may be played either indoors or outdoors. Players of all ages from four years old to more than eighty-four are attracted to participate. Much of the excitement and exercise common to the age-old game of tag are included in the game, however the game requires both less vigor and less space than tag. A certain dexterity to manipulate the sticks and marbles is advantageous, but not necessary. The existence of various strategies of play gives multiple levels of interest to the game. Three qualitatively different ways to play Marble Tag are: as individuals, as partnerships, and with handicaps. Furthermore, other games can be played with the same Marble Tag apparatus or on mazes with minor modifications.

US Patent:

50087401, Apr 16, 1991

Filed:

Apr 14, 1989

Appl. No.:

7/339044

Inventors:

Larry G. Phillips - Knoxville TN
Edwin R. Meyer - Knoxville TN
David C. Greene - Knoxville TN

Assignee:

North American Philips Corp. - New York NY

International Classification:

H04N 965

US Classification:

358 23

Abstract:

Apparatus and methods for remodulating digital luminance and color difference components for display as PIP information, or together with other composite video components for multi-PIP and test pattern applications are disclosed. A digital encoder is used for conducting a digital quadrature modulation on the color difference components and for digitally adding the luminance signal thereto prior to the converting of the remodulated information into an analog format. Preferably, the digital video information output by the encoder is in the form Y1+(R-Y)1, Y1 +(B-Y)1, Y2-(R-Y)1, Y2-(B-Y)1, Y3+(R-Y)2. Y3+(b-Y)2, Y4 -(R-Y)2,. . . , where Y is the luminance component, R-Y and B-Y are color difference components, and where the numbers index received samples of the video components with the luminance component being sampled at twice the frequency of the color difference components. Where digitally modulated composite video is desired, fixed black level, burst, and background values are multiplexed with the active R-Y and B-Y signals, while fixed sync tip, black level, and background values are multiplexed with the active Y signals prior to encoding.

Appl. No.:

7/339032

Inventors:

Larry G. Phillips - Knoxville TN
Edwin R. Meyer - Knoxville TN
David C. Greene - Knoxville TN

Assignee:

North American Philips Corporation - New York NY

International Classification:

H04N 504

US Classification:

358 17

Abstract:

A method and apparatus for synchronizing a received television signal to a subcarrier locked signal is provided. The apparatus includes a comparison block for determining whether the received television signal and subcarrier locked signal are related by a predetermined fixed frequency relationship and for providing indications of the same, and a signal generation block for dividing down the subcarrier locked signal according to the predetermined fixed frequency relationship so as to provide an output signal which is synchronized with the subcarrier locked signal, and at a frequency determined according to the fixed frequency relationship when the signals are related. The apparatus is particularly useful in PIP applications where the received television signal is a horizontal signal and the subcarrier locked signal is a four times multiple of the subcarrier frequency. The comparison block preferably includes a counter and a windowing circuit for determining whether edges of horizontal signal pulses are received within or outside a predetermined time window, and a decision circuit for determining whether the occurrences (counts) of in and out of window edges are indicative of related or unrelated signals. The entire apparatus preferably includes only flip-flops, simple logic gates such as AND, NAND, or OR gates, inverters, multiplexer switches, and resettable counters.

Filed:

Apr 4, 1990

Appl. No.:

7/505089

Inventors:

David C. Greene - Knoxville TN
Edwin R. Meyer - Knoxville TN

Assignee:

North American Philips Corporation - New York NY

International Classification:

H03B 532

US Classification:

331158

Abstract:

A stabilized gated oscillator that provides pulses at a predetermined repetition rate in phase coherence with a gating signal includes a ceramic resonator in a feedback resonant circuit between the output terminal and the input terminal of a linear amplifier. The resonant circuit, which establishes the repetition rate, is constructed to provide an oscillator frequency in a frequency range between two resonant frequencies of the ceramic resonator wherein the ceramic resonator acts as an inductance.

Inventors:

David C. Greene - Knoxville TN

Assignee:

North American Philips Corporation - New York NY

International Classification:

H03B 512

US Classification:

331117R

Abstract:

A gated oscillator circuit for generating a sampling signal for digitally processing television signals, uses an LC oscillator to achieve, high frequency stability and reduced edge jitter. Circuitry is provided on both sides of a tank circuit in the oscillator for decoupling the tank circuit from other active circuit elements thereby enhancing the frequency stability.

Appl. No.:

16/862454

Inventors:

- Cave Creek AZ, US
David Greene - Cave Creek AZ, US

International Classification:

A61B 17/06

Abstract:

A thread lift cannula has a plurality of therapeutic liquid discharge ports to enable the discharge of a therapeutic liquid into the surrounding tissue. The therapeutic liquid may be injected into the thread lift cannula conduit by a syringe and the thread therein may be bioresorbable and absorb the therapeutic liquid. The therapeutic liquid may include a medicament to reduce swelling or to treat pain, or a biologic that aids in collagen creation, formation, or restructuring. The plurality of therapeutic liquid discharge ports may vary in size along the length of the cannula. A distal discharge port may be larger than a proximal discharge port to enable a more uniform delivery of therapeutic liquid along the cannula. A therapeutic liquid discharge port may be configured at a port angle, offset from orthogonally through the wall of the cannula, to prevent blockage of the outlet opening of the discharge port.
