Abstract

Abstract An alarm or indicating system for indicating that an automotive appliance has been left in the vehicle. The system includes a circuit powered by the battery of the vehicle and a first switch which is closed by inserting the appliance into a predetermined position in the vehicle and opened by removing the appliance from the predetermined position. The circuit further includes a control switch that is operated by the door of the vehicle such that when the door is opened the control switch will be closed to energize the circuit of the appliance is in its predetermined position. When the operator removes the appliance it will open the first switch to de-energize the circuit and the alarm. When the door of the vehicle is closed the control switch will be opened and the alarm circuit will be de-energized.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 48 words
A method of protecting against theft an electronic appliance installed in an automotive vehicle comprising the step of releasably connecting the appliance to an indicating circuit to produce an alert signal when the operator leaves the vehicle without removing the appliance from a predetermined position in the vehicle.
Claim 2
Independent Claim 48 words
A method of protecting against theft an electronic appliance installed in an automotive vehicle comprising the step of releasably connecting the appliance to an indicating circuit to produce an alert signal when the operator leaves the vehicle without removing the appliance from a predetermined position in the vehicle.
Claim 3
Dependent Claim 48 words
The method defined in claim 1 further including the steps of using the predetermined position of the appliance in the vehicle to energize the signal only as long as the appliance remains in the predetermined position, and removing the appliance from said predetermined position to de-energize the signal.
Claim 4
Dependent Claim 46 words
The method defined in claim 1 further including the step of connecting the indicating circuit to a switch actuated by the door of the vehicle such that when the door is opened while the appliance is still in said predetermined position the circuit will be energized.
Claim 5
Dependent Claim 46 words
The method defined in claim 2 further including the step of connecting the indicating circuit to a switch actuated by the door of the vehicle such that when the door is opened while the appliance is still in said predetermined position the circuit will be energized.
Claim 6
Dependent Claim 94 words
An indicating system for indicating that an electronic appliance has been left in an automobile vehicle comprising in combination, indicating means for producing a signal, a circuit for energizing said indicating means including a first switch which is closed when the appliance is installed in a predetermined position in the vehicle and which is open when the appliance is removed from said predetermined position, and a control switch for energizing said circuit to energize said indicating means when the appliance is in said predetermined position and said control switch is in a first position.
Claim 7
Dependent Claim 94 words
An indicating system for indicating that an electronic appliance has been left in an automobile vehicle comprising in combination, indicating means for producing a signal, a circuit for energizing said indicating means including a first switch which is closed when the appliance is installed in a predetermined position in the vehicle and which is open when the appliance is removed from said predetermined position, and a control switch for energizing said circuit to energize said indicating means when the appliance is in said predetermined position and said control switch is in a first position.
Claim 8
Dependent Claim 51 words
The indicating system defined in claim 5 wherein said circuit is de-energized when said control switch is in an open position and wherein said first position of said control switch is a closed position which will cause the circuit to be energized if said first switch is in a closed position.
Claim 9
Dependent Claim 35 words
The indicating system defined in claim 6 further including means positioned between said first switch and said indicating means for protecting the indicating means from B+ signals which emanate from the vehicle or switching device.
Claim 10
Dependent Claim 115 words
In an automotive vehicle having an electronic appliance located in a predetermined operative position, said appliance being removable from said operative position, first switch means which is closed when the appliance is placed in said predetermined operative position and which is opened when the appliance is removed from said predetermined operative position; an indicator, a circuit for energizing and de-energizing said indicator including said first switch means, said circuit including a second control switch having a first position for energizing the circuit to energize the indicator when the appliance is in said predetermined operative position thereof, said circuit being de-energized when the appliance is removed from said predetermined position thereby opening said first switch means.
Claim 11
Dependent Claim 115 words
In an automotive vehicle having an electronic appliance located in a predetermined operative position, said appliance being removable from said operative position, first switch means which is closed when the appliance is placed in said predetermined operative position and which is opened when the appliance is removed from said predetermined operative position; an indicator, a circuit for energizing and de-energizing said indicator including said first switch means, said circuit including a second control switch having a first position for energizing the circuit to energize the indicator when the appliance is in said predetermined operative position thereof, said circuit being de-energized when the appliance is removed from said predetermined position thereby opening said first switch means.
Claim 12
Dependent Claim 26 words
The combination defined in claim 8 wherein said control switch has an open position for de-energizing the circuit when the appliance is in said installed position.
Claim 13
Dependent Claim 33 words
The combination defined in claim 9 wherein the vehicle has a door for closing the control switch when the door is opened and for opening the control switch when the door is closed.
Claim 14
Dependent Claim 15 words
The combination defined in claim 9 wherein said control switch is a remote control switch.
Claim 15
Dependent Claim 19 words
The combination defined in claim 8 wherein said circuit includes a diode between said indicator and said first switch.
Claim 16
Dependent Claim 16 words
The combination defined in claim 8 wherein said first switch means is included in said appliance.
