Abstract
Abstract A vehicle alarm triggering system having a trigger switch mounted such that a reverse force applied to the vehicle brake pedal causes either a continuous silent alarm, e.g., a radio signal to be transmitted, or an audible alarm to be activated. The triggering system includes a test mode enabling the alarm to be briefly activated, and a trigger switch such as a dry-reed encapsulated switch activated by a permanent magnet.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A vehicle alarm triggering system for a vehicle having a pedal with a front and a back surface, said pedal being normally activated by applying a positive force against the front surface of the pedal, comprising: triggering means, operatively connected to said pedal, having active and inactive operational states, and arranged to be activated by a reverse force in a direction toward the back surface of said pedal, for providing a trigger signal responsive to the triggering means being activated; and alarm means for providing an alarm signal in response to the trigger signal.
Claim 2
Dependent Claim
94 words
A vehicle alarm triggering system for a vehicle having a pedal with a front and a back surface, said pedal being normally activated by applying a positive force against the front surface of the pedal, comprising: triggering means, operatively connected to said pedal, having active and inactive operational states, and arranged to be activated by a reverse force in a direction toward the back surface of said pedal, for providing a trigger signal responsive to the triggering means being activated; and alarm means for providing an alarm signal in response to the trigger signal.
Claim 3
Dependent Claim
72 words
A vehicle alarm triggering system according to claim 1, further comprising: locking receiving means, operatively connected to receive the trigger signal, for sensing a change in the operational state of the trigger means and for providing a continuous activating signal responsive to the change in the operational state of the trigger means; and alarm means, operatively connected to receive the activating signal, for providing an alarm signal responsive to the activating signal.
Claim 4
Dependent Claim
30 words
A vehicle alarm triggering system according to claim 1, wherein said pedal corresponds to a brake pedal and said triggering means is mounted on the rear of the brake pedal.
Claim 5
Dependent Claim
30 words
A vehicle alarm triggering system according to claim 2, wherein said pedal corresponds to a brake pedal and said triggering means is mounted on the rear of the brake pedal.
Claim 6
Dependent Claim
34 words
A vehicle alarm triggering system according to claim 3, wherein said triggering means comprises one of a dry-reed encapsulated switch, a Hall-effect switch and a mechanical switch, and is operatively connected to the pedal.
Claim 7
Dependent Claim
26 words
A vehicle alarm triggering system according to claim 4, wherein said triggering means comprises one of a dry-reed encapsulated switch, a Hall-effect switch and a relay.
Claim 8
Dependent Claim
26 words
A vehicle alarm triggering system according to claim 3, wherien said alarm means comprises a radio transmitter for transmitting the alarm signal at a predetermined frequency.
Claim 9
Dependent Claim
26 words
A vehicle alarm triggering system according to claim 4, wherein said alarm means comprises a radio transmitter for transmitting the alarm signal at a predetermined frequency.
Claim 10
Dependent Claim
28 words
A vehicle alarm triggering system according to claim 3, wherein said alarm means comprises an astable circuit for activating one of an audible alarm and a silent alarm.
Claim 11
Dependent Claim
28 words
A vehicle alarm triggering system according to claim 4, wherein said alarm means comprises an astable circuit for activating one of an audible alarm and a silent alarm.
Claim 12
Dependent Claim
32 words
A vehicle alarm triggering system according to claim 2, wherein said locking receiving means is operatively connected to receive a test signal, and activates the alarm in response to said test signal.
Claim 13
Dependent Claim
112 words
A vehicle alarm triggering system for connection with a locking receiving circuit and an alarm circuit activated by the locking receiving circuit provided in a vehicle having a pedal with a front and a back surface, said pedal being normally activated by applying a positive force against the front surface of the pedal, said system comprising: triggering means, operatively connected to said pedal and having active and inactive operational states arranged to be activated by a reverse force in a direction toward the back surface of said pedal for providing a trigger signal responsive to the operational states; and means for activating the locking receiving circuit in response to said trigger signal.
Claim 14
Dependent Claim
112 words
A vehicle alarm triggering system for connection with a locking receiving circuit and an alarm circuit activated by the locking receiving circuit provided in a vehicle having a pedal with a front and a back surface, said pedal being normally activated by applying a positive force against the front surface of the pedal, said system comprising: triggering means, operatively connected to said pedal and having active and inactive operational states arranged to be activated by a reverse force in a direction toward the back surface of said pedal for providing a trigger signal responsive to the operational states; and means for activating the locking receiving circuit in response to said trigger signal.
