Abstract

Abstract An electronic drag race starting signal unit includes a housing contained circuit provided with or energizing a series of race starting lamps. The race start indicator or Christmas Tree, which may be a series of LED's, are preferably three aligned amber or yellow lamps terminating in aligned relationship with a red lamp and a green lamp interposed betwen the red lamp and the adjacent yellow lamp. A manually held pushbutton switch, when closed, simulates a vehicle transmission brake and energizes the circuit to sequentially or simultaneously energize the yellow lamps followed by the green lamp which is the start signal. A counter in the circuit visually records the time lapse between the start signal and the release (opening) of the push-button switch by the operator which, if it is received before a predetermined time, energizes the red lamp as a disqualification.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 214 words
An electronic simulated racing vehicle brake release and driver start signal reaction timer, comprising: a housing containing an electronic circuit connected with a source of electrical energy and including; a plurality of lamps arranged in generally straight line relation and including first, second and third lamps having one color, a fourth lamp having a second color and a fifth lamp having a third color; means including a counter for sequentially energizing said lamps at predetermined times starting with said first lamp through at least the fourth lamp; push-button switch means simulating a racing vehicle transmission brake or wheel brake and enabling the sequential energizing means when said push-button switch means is closed and disabling the sequential energizing means when the push-button switch means is opened before a predetermined time lapse; and, means including a digital display unit visually recording the time lapse between energizing said third lamp and the opening of said push-button switch means during one predetermined time period so that said fourth lamp is energized with the opening of said push-button switch when opened no sooner than at the end of said time period, but where said fifth lamp is energized with the fourth lamp inhibited by said push-button switch when said switch is opened before the expiration of said time period.
Claim 2
Dependent Claim 214 words
An electronic simulated racing vehicle brake release and driver start signal reaction timer, comprising: a housing containing an electronic circuit connected with a source of electrical energy and including; a plurality of lamps arranged in generally straight line relation and including first, second and third lamps having one color, a fourth lamp having a second color and a fifth lamp having a third color; means including a counter for sequentially energizing said lamps at predetermined times starting with said first lamp through at least the fourth lamp; push-button switch means simulating a racing vehicle transmission brake or wheel brake and enabling the sequential energizing means when said push-button switch means is closed and disabling the sequential energizing means when the push-button switch means is opened before a predetermined time lapse; and, means including a digital display unit visually recording the time lapse between energizing said third lamp and the opening of said push-button switch means during one predetermined time period so that said fourth lamp is energized with the opening of said push-button switch when opened no sooner than at the end of said time period, but where said fifth lamp is energized with the fourth lamp inhibited by said push-button switch when said switch is opened before the expiration of said time period.
Claim 3
Dependent Claim 69 words
The reaction timer according to claim 1 in which said sequential energizing means includes: an oscillator; a plurality of decade counters connected in cascade with said oscillator for predetermined time spacing the electrical pulses from said oscillator; a sequencer connecting the electrical pulses from said decade counters with said lamps; and, a plurality of electronic switch means interposed between the sequencer and at least said fourth and fifth lamps.
Claim 4
Dependent Claim 83 words
The reaction timer according to claim 2 and further including: means simulating a vehicle delay response time including a vehicle timer interposed between the push-button means and the sequencer; means for adjusting the vehicle time delay to a desired value; and, a series of other electronic switch means connected with said counter/driver and responsive to selected lamp energizing electrical pulses for enabling or blocking the energizing of said fifth lamp in accordance with a predetermined time lapse following energizing of said fourth lamp.
Claim 5
Dependent Claim 31 words
The reaction timer according to claim 3 and further including: mode switch means interposed between said sequencer and said lamps for enabling the sequencer to simultaneously energize the first three lamps.
Claim 6
Dependent Claim 54 words
The reaction timer according to claim 4 and further including: electronic signal delay means including a signal inverting latch interposed between said oscillator and said sequencer for resetting the sequencer output thereby generating a random time delay between the time of closing said push-button switch means and the start of sequentially energizing said lamps.
