Abstract
Abstract An apparatus for monitoring tire pressure on automobiles, having an arrangement (1), intended for installation into a wheel, made up of a pressure sensor, a transmitter, and a circuit for operating the pressure sensor and transmitter, and having a battery (2) which supplies the circuit with power via a power supply line (3), the arrangement (1) and the battery (2) being located in a sealed housing (9). Located in the power supply line (3) is an electronic switch (4) which has a control electrode (5) and is nonconductive when the control electrode (5) is connected to ground.

Claim 1
Independent Claim
132 words
An apparatus for monitoring tire pressure on automobiles, having an arrangement (1), intended for installation into a wheel, made up of a pressure sensor, a transmitter, and a circuit for operating the pressure sensor and transmitter, and having a battery (2) which supplies the circuit with power via a power supply line (3), the arrangement (1) and the battery (2) being located in a sealed housing (9), wherein there is located in the power supply line (3) an electronic switch (4) which has a control electrode (5) and is nonconductive when the control electrode (5) is connected to ground, where the line (6) can be permanently interrupted between the control electrode (5) and ground by a measure to be effected on the housing (9), for purposes of setting the arrangement into operation.
Claim 2
Independent Claim
132 words
An apparatus for monitoring tire pressure on automobiles, having an arrangement (1), intended for installation into a wheel, made up of a pressure sensor, a transmitter, and a circuit for operating the pressure sensor and transmitter, and having a battery (2) which supplies the circuit with power via a power supply line (3), the arrangement (1) and the battery (2) being located in a sealed housing (9), wherein there is located in the power supply line (3) an electronic switch (4) which has a control electrode (5) and is nonconductive when the control electrode (5) is connected to ground, where the line (6) can be permanently interrupted between the control electrode (5) and ground by a measure to be effected on the housing (9), for purposes of setting the arrangement into operation.
Claim 3
Dependent Claim
55 words
The apparatus as defined in claim 1, wherein the housing (9) has a housing wall with a flexibly configured segment (12) on the inner side of which is arranged an interrupter (7) that can be opened by being pressed in and is located in the line (6) which connects the control electrode (5) to ground.
Claim 4
Dependent Claim
51 words
The apparatus as defined in claim 1, wherein the housing (9) has a housing wall with a flexibly configured segment (12) on the inner side of which is arranged a segment of the line (6) connecting the control electrode (5) to ground that can be broken off by being pressed in.
Claim 5
Dependent Claim
38 words
The apparatus as defined in claim 3, wherein the line (6) which connects the control electrode (5) to ground has one or more defined break points (13, 14) on the flexibly configured segment (12) of the housing wall.
Claim 6
Dependent Claim
28 words
The apparatus as defined in claim 1, wherein the line which connects the control electrode (5) to ground runs partially on the outer side of the housing (9).
Claim 7
Dependent Claim
44 words
The apparatus as defined in claim 5, wherein that portion of the line (6) connecting the control electrode (5) to ground which runs on the outer side of the (9) has a loop (8) standing out from the outer side of the housing (9).
Claim 8
Dependent Claim
27 words
The apparatus as defined in claim 6, wherein the loop (8) has defined break points (10, 11) just next to the outer side of the housing (9).
Claim 9
Dependent Claim
44 words
The apparatus as defined in claim 6, wherein the housing (9) with the externally located loop (8) is dimensioned, in accordance with the predefined installation conditions on the wheel, that installation into the wheel absolutely requires that the loop (8) first be broken off.
Claim 10
Dependent Claim
41 words
The apparatus as defined in claim 7, wherein the housing with the externally located loop is dimensioned, in accordance with the predefined installation conditions on the wheel, that installation into the wheel absolutely requires that that loop first be broken off.
