Abstract
Abstract The present invention provides a portable microcomputer-implemented bowling aid which indicates to the bowler (i) correct starting position and (ii) correct board marker over which to roll the ball after its released so as to maximize pin count with minimum data entry problems. In accordance with one aspect of the present invention, the bowler first inputs game parameters such as right- or left-handness through I/O elements to a RAM of a microcomputer operationally connected to a bowling alley replica display. The replica display includes representations of (a) triangularly configured pins 1, 2, 3, . . . 10, (b) the bowling lane, (c) the foul line, (d) a series of board markers or spots adjacent to the foul line but on the pin side thereof and (e) a series of foot positions to the start of the bowler's approach to delivery of the bowling ball. The representations related to (a), (d) and (e) are keyed together by programing steps. As a result, control signals are generated by the microcomputer to control a logic driver circuit in series with LEDs of (d) and (e), supra. However, the drive current for the LEDs is not sourced from within the microcomputer. The algorithm for operations is in ROM stepped through operations by the CPU within the microcomputer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
276 words
A portable microcomputer-implemented apparatus and system for teaching bowling comprising: (a) a viewing surface having a series of indicia representative of an actual bowling alley lane; (b) a microcomputer supported adjacent to said viewing surface; (c) viewable light emitting means supported adjacent to said viewing surface and said series of indicia in operative contact with said microcomputer; (d) said light emitting means defining positions on said viewing surface corresponding to: (i) at least a pair of board markers; and (ii) a series of start foot positions for a bowler on said actual bowling alley lane; (e) switch means in scanning contact with said microcomptuer positioned adjacent to said viewing surface and having at least ten contact positions, each of said at least ten contact positions corresponding to one of ten bowling pin positions of said actual bowling alley lane; and (f) driver logic means in operative contact with and controllable by control signals generated by said microcomputer for selectively coupling said light emitting means to a drive current sourced independently from said microcomputer, said selective coupling being based on scanned closure of said at least ten positions of said switch means by said microcomputer to indicate correct foot and aim positions by said light emitting means to teach a bowler where to stand and aim to convert a particular standing pin configuration; and (g) said driver logic means includes a current source, first and second series of EXCLUSIVE-OR gates, each having first and second inputs and an output, and a series of latches each having a D input, a G input and a Q output to selectively activate said light emitting means with said drive current.
Claim 2
Dependent Claim
276 words
A portable microcomputer-implemented apparatus and system for teaching bowling comprising: (a) a viewing surface having a series of indicia representative of an actual bowling alley lane; (b) a microcomputer supported adjacent to said viewing surface; (c) viewable light emitting means supported adjacent to said viewing surface and said series of indicia in operative contact with said microcomputer; (d) said light emitting means defining positions on said viewing surface corresponding to: (i) at least a pair of board markers; and (ii) a series of start foot positions for a bowler on said actual bowling alley lane; (e) switch means in scanning contact with said microcomptuer positioned adjacent to said viewing surface and having at least ten contact positions, each of said at least ten contact positions corresponding to one of ten bowling pin positions of said actual bowling alley lane; and (f) driver logic means in operative contact with and controllable by control signals generated by said microcomputer for selectively coupling said light emitting means to a drive current sourced independently from said microcomputer, said selective coupling being based on scanned closure of said at least ten positions of said switch means by said microcomputer to indicate correct foot and aim positions by said light emitting means to teach a bowler where to stand and aim to convert a particular standing pin configuration; and (g) said driver logic means includes a current source, first and second series of EXCLUSIVE-OR gates, each having first and second inputs and an output, and a series of latches each having a D input, a G input and a Q output to selectively activate said light emitting means with said drive current.
Claim 3
Dependent Claim
37 words
