Abstract
Abstract The present invention is a remote control targeting and control system for use with a standard raster scanned television and an associated gaming unit. The remote control system includes a mobile transceiver and a fixed transceiver which communicates with the gaming system. The system implements a simple communication system which allows the mobile transceiver to ordinarily transmit position data and to periodically transmit button press data. The mobile transceiver includes an electro-optic detector for observing when a scan line crosses a target area. Each time a scan line is detected, the mobile transceiver transmits a pulse to the fixed unit, based upon which the gaming unit translate the pulse into position data based on the time of its detection. The button press data is transmitted synchronously with the raster scanned television in that the fixed transceiver is caused to transmit a single pulse during each vertical retrace of the television. The preferred remote control system is contained in a gun-shaped main unit of a multipiece housing. A stalk and a sighting system having viewing tubes may be optionally attached to the main unit. The sighting system is comprised of a pair of viewing tubes and a rotatable sighting tube which may be place in front of either sighting tube.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
197 words
A video system comprising: an electronic gaming unit which executes a game program and which generates a video signal in response thereto; a raster scanned video display terminal which displays a video image in response to said video signal, two alternating time phases being used to display said video image, an image phase during which horizontal scan lines are displayed and a blank phase during which the display is blank; and a remote control system for controlling the game program including: a fixed transceiver having a transmission means for transmitting time phase information denoting the blank phase and a receiving means for receiving data; a mobile transceiver including at least one button which may be activated by a user and means for generating button-press data in response thereto, an optical sensor means for observing a target area on the raster scanned video display terminal, a receiving means for receiving the time phase information from the transmission means of said fixed transceiver, and a transmission means for transmitting data, said mobile transceiver transmitting the button-press data during the blank phase in response to the time phase information only and transmitting the image position data during the image phase.
Claim 2
Dependent Claim
197 words
A video system comprising: an electronic gaming unit which executes a game program and which generates a video signal in response thereto; a raster scanned video display terminal which displays a video image in response to said video signal, two alternating time phases being used to display said video image, an image phase during which horizontal scan lines are displayed and a blank phase during which the display is blank; and a remote control system for controlling the game program including: a fixed transceiver having a transmission means for transmitting time phase information denoting the blank phase and a receiving means for receiving data; a mobile transceiver including at least one button which may be activated by a user and means for generating button-press data in response thereto, an optical sensor means for observing a target area on the raster scanned video display terminal, a receiving means for receiving the time phase information from the transmission means of said fixed transceiver, and a transmission means for transmitting data, said mobile transceiver transmitting the button-press data during the blank phase in response to the time phase information only and transmitting the image position data during the image phase.
Claim 3
Dependent Claim
39 words
The video system of claim 1 wherein the transmission means of the mobile and fixed transceivers are comprised of IR transmitting diodes and wherein the reception means of the mobile and fixed transceivers are comprised of IR sensitive diodes.
Claim 4
Dependent Claim
26 words
The video system of claim 1 wherein the transmission means of the fixed transceiver transmits only a single pulse at the beginning of the blank phase.
Claim 5
Dependent Claim
52 words
The video system of claim 3 wherein the means for generating button-press data is comprised of a means for detecting the single pulse transmitted by the fixed transceiver and a means for generating the button-press data based on the buttons which are depressed when the means for detecting detects the single pulse.
Claim 6
Dependent Claim
29 words
The video system of claim 4 wherein the button-press data is a pulse-train comprising a series of pulses, the number of pulses representing which of the buttons were depressed.
Claim 7
Independent Claim
208 words
A method of synchronizing remote control signals in a video gaming system in which a gaming computer generates a raster scanned image on a video display terminal, using two separate time phases to display said video image, an image phase during which horizontal scan lines are displayed and a blank phase during which the display is blank, the method of comprising the steps of: placing a fixed transceiver for transmitting information and for receiving data in proximity to the video display terminal and in electronic communication with the gaming computer; providing a mobile transceiver, including at least one button which may be activated by a user to generate button-press data, an optical sensor to observe a target area on the video display terminal, electronics connected to said optical sensor to generate positional data, a receiver for receiving the information from said fixed transceiver and a transmitter for transmitting button-press and positional data to the fixed transceiver; transmitting time phase information from the fixed transceiver to the mobile transceiver, the information indicating when the blank phase begins; and transmitting button-press data, based on the time phase information, so that button-press data is transmitted only during the blank phase and the positional data is transmitted only during the image phase.
