Abstract
Abstract A warning apparatus for a vehicle in which a plurality of detecting devices are arranged to be operated in response to respective input signals which are different in degree of importance. The detecting devices are provided on their output sides with respective sound signal sources so that, when any one of the detecting devices is selectively operated, the corresponding one of the sound signal sources is also selectively operated. In the event that two or more detecting devices are simultaneously operated, a single signal source corresponding to the input signal highest in degree of importance is selected for operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
Warning apparatus comprising a plurality of detecting devices for detecting different conditions having sequential degrees of importance, alarm means responsive to said detecting devices for producing respective and different sound alarms for each condition, and further means coupling said devices to said alarm means and providing, in the event of simultaneous operation of more than one said device, for the producing of a sound alarm corresponding only to the detected condition of highest degree of importance, said further means including a plurality of parallel circuits coupled between respective of said devices and said alarm means, relay coils in respective of said circuits and contact means cooperating with said coils and arranged in respective of said circuits to open the circuits corresponding to lesser degrees of importance when a circuit corresponding to a higher degree of importance is actuated.
Claim 2
Dependent Claim
138 words
Warning apparatus comprising a plurality of detecting devices for detecting different conditions having sequential degrees of importance, alarm means responsive to said detecting devices for producing respective and different sound alarms for each condition, and further means coupling said devices to said alarm means and providing, in the event of simultaneous operation of more than one said device, for the producing of a sound alarm corresponding only to the detected condition of highest degree of importance, said further means including a plurality of parallel circuits coupled between respective of said devices and said alarm means, relay coils in respective of said circuits and contact means cooperating with said coils and arranged in respective of said circuits to open the circuits corresponding to lesser degrees of importance when a circuit corresponding to a higher degree of importance is actuated.
Claim 3
Dependent Claim
138 words
Warning apparatus comprising a plurality of detecting devices for detecting different conditions having sequential degrees of importance, alarm means responsive to said detecting devices for producing respective and different sound alarms for each condition, and further means coupling said devices to said alarm means and providing, in the event of simultaneous operation of more than one said device, for the producing of a sound alarm corresponding only to the detected condition of highest degree of importance, said further means including a plurality of parallel circuits coupled between respective of said devices and said alarm means, relay coils in respective of said circuits and contact means cooperating with said coils and arranged in respective of said circuits to open the circuits corresponding to lesser degrees of importance when a circuit corresponding to a higher degree of importance is actuated.
Claim 4
Dependent Claim
138 words
Warning apparatus comprising a plurality of detecting devices for detecting different conditions having sequential degrees of importance, alarm means responsive to said detecting devices for producing respective and different sound alarms for each condition, and further means coupling said devices to said alarm means and providing, in the event of simultaneous operation of more than one said device, for the producing of a sound alarm corresponding only to the detected condition of highest degree of importance, said further means including a plurality of parallel circuits coupled between respective of said devices and said alarm means, relay coils in respective of said circuits and contact means cooperating with said coils and arranged in respective of said circuits to open the circuits corresponding to lesser degrees of importance when a circuit corresponding to a higher degree of importance is actuated.
Claim 5
Dependent Claim
75 words
Apparatus as claimed in claim 1 comprising a second plurality of circuits corresponding to the first plurality, contact means in the second plurality corresponding to and operable with the first said contact means, switches coupling respective and corresponding of parallel circuits, a solenoid for sequentially operating said switches, and coils coupled to respective of said pluralities of parallel circuits for twisting the solenoid on and off to control the extent of movement of the same.
Claim 6
Dependent Claim
23 words
Apparatus as claimed in claim 2 comprising a selection means controlled by said solenoid to select a sound alarm from said alarm means.
Claim 7
Dependent Claim
