Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
189 words
A cycle alarm, comprising: an enclosure adapted to be secured to a cycle; angle-sensing switch means secured to and within said enclosure, comprising a first switch having a first condition in which it remains so long as said enclosure is positioned within a predetermined range of angular positions with respect to the vertical and responsive to a departure of said enclosure from said range of angular positions to actuate said first switch to a second condition thereof; a source of electrical supply voltage within said enclosure; alarm means within said enclosure for generating alarm signals when supplied with said supply voltage; means connecting said source and said first switch with said alarm means to generate said alarm signals when said first switch is actuated to said second condition thereof; means for continuing said alarm signals for at least a predetermined interval after each actuation of said first switch to said second condition despite return of said switch to said first condition thereof, and for terminating said alarm signals automatically at a time following return of said switch to said first condition by an interval equal to said predetermined interval.
Claim 2
Dependent Claim
189 words
A cycle alarm, comprising: an enclosure adapted to be secured to a cycle; angle-sensing switch means secured to and within said enclosure, comprising a first switch having a first condition in which it remains so long as said enclosure is positioned within a predetermined range of angular positions with respect to the vertical and responsive to a departure of said enclosure from said range of angular positions to actuate said first switch to a second condition thereof; a source of electrical supply voltage within said enclosure; alarm means within said enclosure for generating alarm signals when supplied with said supply voltage; means connecting said source and said first switch with said alarm means to generate said alarm signals when said first switch is actuated to said second condition thereof; means for continuing said alarm signals for at least a predetermined interval after each actuation of said first switch to said second condition despite return of said switch to said first condition thereof, and for terminating said alarm signals automatically at a time following return of said switch to said first condition by an interval equal to said predetermined interval.
Claim 3
Dependent Claim
86 words
The cycle alarm of claim 1, in which said angle-sensing means comprises a second switch in parallel with said first switch, said first switch being actuated to its closed condition when said enclosure departs from said range of angular positions in one angular sense, and said second switch being operated to its closed condition when said enclosure departs from said angular range in the opposite angular sense, each of said first and second switches being independently settable to different angular positions with respect to said enclosure.
Claim 4
Dependent Claim
28 words
The cycle alarm of claim 1, in which said alarm means comprises sound generating means responsive to supply thereto of said supply voltage to sound an audible alarm.
Claim 5
Dependent Claim
45 words
The cycle alarm of claim 3, comprising electronic switch means connected between said source and said sound generating means, said electronic switch means being normally open but responsive to actuation of said first switch to said second condition to be rendered conductive at least intermittently.
Claim 6
Dependent Claim
34 words
The cycle alarm of claim 4, comprising means responsive to actuation of said first switch to said second condition to render said electronic switch means intermittently conductive, thereby to sound said audible alarm intermittently.
Claim 7
Dependent Claim
39 words
The cycle alarm of claim 1, comprising a trigger circuit connected between said first switch and said alarm means initiating operation of said alarm means only when the voltage supplied to said trigger circuit rises above a predetermined level.
Claim 8
Dependent Claim
67 words
The cycle alarm of claim 6, comprising resistance-capacitance timing circuit means connected between said source and said trigger circuit by way of said first switch for providing prompt turn-on of said trigger circuit when said first switch is actuated to said second condition and for delaying by a predetermined time interval the turn-off of said trigger circuit when said first switch is returned to said first condition.
Claim 9
Dependent Claim
26 words
The cycle alarm of claim 1, comprising a key switch on said enclosure connected to control connection of said source to the remainder of the circuit.
Claim 10
Dependent Claim
62 words
The cycle alarm of claim 8, comprising capacitance means for maintaining operation of said alarm means for a predetermined time interval after each actuation of said first switch to said second condition, and diode means connected to discharge said capacitance means more rapidly when said key switch is open than when said key switch is closed and said first switch is open.
Claim 11
Dependent Claim
64 words
The cycle alarm of claim 1, in which said enclosure is provided with a removable cover portion, and with another portion mountable to said cycle and having fastening means operable only from the interior of said enclosure to remove said enclosure from said cycle, said enclosure containing additional switch means operable in response to removal of said cover portion to operate said alarm means.
Claim 12
Dependent Claim
32 words
The cycle alarm of claim 1, in which said alarm means comprises means responsive to application thereto of said supply voltage to generate audio-modulated radio-frequency signals for radiation to a remote receiver.
