Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
An electronic device for decisions and scoring comprising at least three control boxes, each having designated decision members each switchable between two logic states by a person to indicate a decision or score, an indicator panel forming part of one of said boxes having energizable indicator means designed to correspond to the decision members, audible indicator means connected to the said indicator panel, and electronic digital logic circuitry means between the decision members in the control boxes and the energizable indicator means in the panel, the digital logic circuitry means being arranged to actuate the indicator means when similarly designated decision members situated in at least two separate control boxes are actuated to establish a predetermined logic pattern in the said logic circuitry means whereby the indicator means indicates the logic pattern of such actuated decision members, and the audible indicator means being arranged to be actuated when a selected condition of said logic pattern occurs.
Claim 2
Dependent Claim
156 words
An electronic device for decisions and scoring comprising at least three control boxes, each having designated decision members each switchable between two logic states by a person to indicate a decision or score, an indicator panel forming part of one of said boxes having energizable indicator means designed to correspond to the decision members, audible indicator means connected to the said indicator panel, and electronic digital logic circuitry means between the decision members in the control boxes and the energizable indicator means in the panel, the digital logic circuitry means being arranged to actuate the indicator means when similarly designated decision members situated in at least two separate control boxes are actuated to establish a predetermined logic pattern in the said logic circuitry means whereby the indicator means indicates the logic pattern of such actuated decision members, and the audible indicator means being arranged to be actuated when a selected condition of said logic pattern occurs.
Claim 3
Dependent Claim
64 words
An electronic device according to claim 1 characterized in that three control boxes are used and two of the said control boxes are remote from the said third box and are connected by cable means to the said third control box, and the said third control box carries the said digital logic circuitry means and the said indicator panel to form a MASTER unit.
Claim 4
Dependent Claim
23 words
An electronic device according to claim 2 characterized in that the said audible indicator means are also carried by the said MASTER unit.
Claim 5
Dependent Claim
59 words
An electronic device according to claim 2 characterized in that the said MASTER unit comprises a box having a front panel, push buttons on the said panel connected to actuate the said switchable decision members, and a series of lights forming the said energizable indicator means also on said panel, said MASTER unit incorporating the said audible indicator means.
Claim 6
Dependent Claim
51 words
An electronic device according to claim 4 characterized in that the said MASTER unit and the said remote units have the said decision members arranged in corresponding positions the one to each other and in that the said energizable indicator means are arranged in corresponding positions the one to each other.
Claim 7
Dependent Claim
53 words
An electronic device according to claim 4 characterized in that the said box of the MASTER unit has a handle pivoted to the box to extend therefrom to allow the box to be supported in a tilted position, and by means to connect electrical transmission cables from each to the said remote boxes.
Claim 8
Dependent Claim
58 words
An electronic device according to claim 1 arranged as a scoring device for the game of squash having the said decision members on each box identified as STROKE, LET, NO LET, UP, NOT UP, IN and OUT, and in that the said audible alarm is actuated when either the OUT or the NOT up decision members are actuated.
Claim 9
Dependent Claim
48 words
An electronic device according to claim 1 characterized in that the said audible indicator means comprise an OR gate connected to be triggered by a signal from selected decision members and connected to initiate a relay in turn connected to impress an audible signal on a loud speaker.
Claim 10
Dependent Claim
20 words
An electronic device according to claim 8 characterized by a manual switch connected to also trigger the said OR gate.
