Abstract
Abstract Individual/driver-defined durations of lever-off automotive turn signaling are provided in response to the application of one or more "taps" to a vehicle's signal lever. A counter is incremented for each tap detected by monitoring circuitry. A non-zero tap count imparts the timing out of lever-off signaling. A timed-signaling duration is the sum of either one or a series of predetermined-length, tap-associated duration segments. As each segment is timed out, the tap counter is decremented. On-the-fly extensions of the duration are enabled. Reset provisions and the transparent invoking means preclude conflicts with non-timed signaling.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
348 words
An apparatus for providing momentary-activation-defined durations of motor vehicle turn signaling in a turn signal system having a means for selecting either left or right, and either momentary or latched signal activations, said apparatus comprising: means for detecting said momentary activations of said selecting means of said turn signal system; means for counting and maintaining a count total of said momentary activations; means for timing successive pre-determined lengths of time, said timing means becoming operative when said count total is non-zero, said timing means decrementing said count total upon a passage of each successive pre-determined length of time; means for detecting a right or left direction of said momentary activations; a first switching means for conducting pulsed battery current to a right signal lamp, said first switching means conducting said pulsed current when said selecting means of said turn signal system is in a right activation position, said first switching means also conducting said pulsed current when said means for timing successive pre-determined lengths of time is operative and said direction detecting means indicates a right direction for a last momentary activation; a second switching means for conducting pulsed battery current to a left signal lamp, said second switching means conducting said pulsed current when said selecting means of said turn signal system is in a left activation position, said second switching means also conducting said pulsed current when said means for timing successive pre-determined lengths of time is operative and said direction detecting means indicates a left direction for a last momentary activation; means for blocking a count of a momentary activation when said timing means is operative and said means for detecting a right or left direction of said activation detects a direction different from a last direction detected; means for deactivating said means for timing and for resetting said count total to zero when said selecting means of said turn signal system is latched or momentarily activated in a direction different from a last direction detected by said direction detecting means; and means for generating an audible signal upon each count of a momentary activation.
Claim 2
Independent Claim
348 words
An apparatus for providing momentary-activation-defined durations of motor vehicle turn signaling in a turn signal system having a means for selecting either left or right, and either momentary or latched signal activations, said apparatus comprising: means for detecting said momentary activations of said selecting means of said turn signal system; means for counting and maintaining a count total of said momentary activations; means for timing successive pre-determined lengths of time, said timing means becoming operative when said count total is non-zero, said timing means decrementing said count total upon a passage of each successive pre-determined length of time; means for detecting a right or left direction of said momentary activations; a first switching means for conducting pulsed battery current to a right signal lamp, said first switching means conducting said pulsed current when said selecting means of said turn signal system is in a right activation position, said first switching means also conducting said pulsed current when said means for timing successive pre-determined lengths of time is operative and said direction detecting means indicates a right direction for a last momentary activation; a second switching means for conducting pulsed battery current to a left signal lamp, said second switching means conducting said pulsed current when said selecting means of said turn signal system is in a left activation position, said second switching means also conducting said pulsed current when said means for timing successive pre-determined lengths of time is operative and said direction detecting means indicates a left direction for a last momentary activation; means for blocking a count of a momentary activation when said timing means is operative and said means for detecting a right or left direction of said activation detects a direction different from a last direction detected; means for deactivating said means for timing and for resetting said count total to zero when said selecting means of said turn signal system is latched or momentarily activated in a direction different from a last direction detected by said direction detecting means; and means for generating an audible signal upon each count of a momentary activation.
Claim 3
Dependent Claim
42 words
The apparatus of claim 1 further comprising means for generating a second audible signal upon each reset of said count total by said resetting means, said second audible signal distinct from said audible signal generated upon each count of a momentary activation.
Claim 4
Dependent Claim
49 words
The apparatus of claim 1 further comprising means for resetting said count total to zero when said selecting means of said turn signal system is unlatched from a latched activation, said selecting means being unlatched either manually by a vehicle operator or automatically upon completion of a vehicle turn.
Claim 5
Dependent Claim
37 words
The apparatus of claim 1 further comprising means for unlatching said means of said turn signal system from a latched activation when a non-zero count total is decremented to a zero count total by said timing means
Claim 6
Dependent Claim
83 words
The apparatus of claim 1 further comprising a visual signal indicator array, said indicator array comprising: a plurality of right side visual indicators for indicating said count total when said detecting means detects a right direction of a last momentary activation; a plurality of left side visual indicators for indicating said count total when said detecting means detects a left direction of a last momentary activation; and means for deactivating said right and left side visual indicators upon said count total being zero
Claim 7
Dependent Claim
55 words
The apparatus of claim 5 further comprising means for activating all of said plurality of right side visual indicators on a selection of a right latched activation of said turn signal system, and all of said plurality of left side visual indicators on a selection of a left latched activation of said turn signal system.
Claim 8
Dependent Claim
55 words
The apparatus of claim 1 wherein said means for generating an audible signal upon each count of a momentary activation further comprises means for buffering said count of momentary activations and generating an audible signal comprising a timed sequence of tones and pauses of equal duration, a number of said tones equal to said count.
Claim 9
Dependent Claim
20 words
The apparatus of claim 1 further comprising means for modifying said pre-determined lengths of time measured by said timing means.
Claim 10
Dependent Claim
41 words
The apparatus of claim 2 further comprising means for generating a third audible signal when a non-zero count total is decremented to a zero count total by said timing means or when said selecting means is unlatched from a latched activation.
