Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 158 words
A self leveling sensitivity adjustable vehicular alarm apparatus comprising: a. a non conducting base mount; b. a first conducting weighted shaft suspended from and pivotally connected to said mount at a first pivot point wherein said fIrst shaft includes a conducting ring adjustably connected to and disposed at a variable angle to said first shaft, wherein said conducting ring constitutes a first contact point and a sensitivity control; c. a second conducting weighted shaft independently suspended from and pivotally connected to a second pivot point wherein said second shaft has a rate of swing different from the rate of swing of said first shaft and is positioned to pass through the center of said conducting ring, wherein said second shaft constitutes a second contact point; and d. an alarm means electrically connected to said first and second contact points wherein said means is activated when said first and second contact points come into physical contact with each other.
Claim 2
Dependent Claim 158 words
A self leveling sensitivity adjustable vehicular alarm apparatus comprising: a. a non conducting base mount; b. a first conducting weighted shaft suspended from and pivotally connected to said mount at a first pivot point wherein said fIrst shaft includes a conducting ring adjustably connected to and disposed at a variable angle to said first shaft, wherein said conducting ring constitutes a first contact point and a sensitivity control; c. a second conducting weighted shaft independently suspended from and pivotally connected to a second pivot point wherein said second shaft has a rate of swing different from the rate of swing of said first shaft and is positioned to pass through the center of said conducting ring, wherein said second shaft constitutes a second contact point; and d. an alarm means electrically connected to said first and second contact points wherein said means is activated when said first and second contact points come into physical contact with each other.
Claim 3
Dependent Claim 138 words
A vehicular alarm system comprising: a. a power source; b. an alarm module; c. a master switch connected between said power source and said alarm module; d. a movement responsive switch for connecting said alarm module to said power source having a non conducting mount and two independently suspended conducting shafts, one of which includes an adjustably connected conducting ring disposed thereto at a variable angle and through which passes the other conducting shaft; e. delay relay means having normally closed contacts for opening said contacts to break the circuit and stop the alarm after a predetermined length of time; and f. a latching relay responsive to the closing of the contacts of said movement responsive switch to maintain power to said delay relay means and to maintain the connection of said power source to said alarm module.
Claim 4
Dependent Claim 138 words
A vehicular alarm system comprising: a. a power source; b. an alarm module; c. a master switch connected between said power source and said alarm module; d. a movement responsive switch for connecting said alarm module to said power source having a non conducting mount and two independently suspended conducting shafts, one of which includes an adjustably connected conducting ring disposed thereto at a variable angle and through which passes the other conducting shaft; e. delay relay means having normally closed contacts for opening said contacts to break the circuit and stop the alarm after a predetermined length of time; and f. a latching relay responsive to the closing of the contacts of said movement responsive switch to maintain power to said delay relay means and to maintain the connection of said power source to said alarm module.
Claim 5
Dependent Claim 34 words
A vehicular alarm system according to claim 2 comprising further a circuit connecting the vehicular lights to said movement responsive switch and causing the lights to turn on and off simultaneously with said alarm.
Claim 6
Dependent Claim 155 words
A vehicular alarm system comprising: a. a power source; b. an alarm module; c. a master switch connected between said power source and said alarm module; d. a movement responsive switch for connecting said alarm module to said power source wherein said switch includes a weighted conducting shaft suspended through a pair of concentric conducting rings, each of which is rotatable with respect to the other to facilitate a sensitivity adjustment wherein said conducting shaft constitutes a first contact point and either of said conducting rings constitutes a second contact point; e. delay relay means having normally closed contacts for opening said contacts to break the circuit and stop the alarm after a predetermined length of time; and f. a latching relay responsive to the closing of the contacts of said movement responsive switch to maintain power to said delay relay means and to maintain the connection of said power source to said alarm module.
Claim 7
Dependent Claim 155 words
A vehicular alarm system comprising: a. a power source; b. an alarm module; c. a master switch connected between said power source and said alarm module; d. a movement responsive switch for connecting said alarm module to said power source wherein said switch includes a weighted conducting shaft suspended through a pair of concentric conducting rings, each of which is rotatable with respect to the other to facilitate a sensitivity adjustment wherein said conducting shaft constitutes a first contact point and either of said conducting rings constitutes a second contact point; e. delay relay means having normally closed contacts for opening said contacts to break the circuit and stop the alarm after a predetermined length of time; and f. a latching relay responsive to the closing of the contacts of said movement responsive switch to maintain power to said delay relay means and to maintain the connection of said power source to said alarm module.
Claim 8
Dependent Claim 31 words
A vehicular alarm system according to claim 4 comprising further a circuit connecting the vehicular lights to said movement responsive switch and causing the lights to turn on and off simultaneously.
