Toll transponder with deactivation means
First Claim
Patent Images
1. A transponder system for use in conjunction with an interrogator of a toll highway comprising:
- a. a transponder which comprises a transponder electronic circuitry which enables interaction with an optical switch, said circuitry being encased within an essentially closed casing, said transponder having two modes;
I. an “
active-responsive”
mode during which the transponder is continuously in standby, while upon receipt of an interrogator signal it responds by sending an identification signal; and
II. an “
inactive-not responsive”
mode during which the transponder does not respond to any interrogation signal;
b. a non-electronically activated switch within the transponder casing having two states, a first state in which it causes the transponder to be in said “
active-responsive”
mode, and a second state in which it causes the transponder to be in said “
inactive-not responsive”
mode;
c. a non-electronic hanging device for placement of the transponder therein, said hanging device being attached to a part of the vehicle where the transponder, when placed, is capable of receiving interrogating signals coming from a proximate interrogator; and
d. a non-electronic activator at said hanging device for causing said non-electronically activated switch to transfer into said first state upon placement of the transponder within said non-electronic hanging device, thereby causing the transponder to be in said “
active-responsive”
mode, and for causing said non-electronically activated switch to transfer into said second state upon removal of the transponder from said non-electronic hanging device, thereby causing the transponder to transfer into said “
inactive-not responsive”
mode, therefore, the mere existence of said transponder casing within said hanging device provides to a vehicle driver a clear indication that the transponder is in the “
active-responsive”
mode, while absence of the transponder casing from said hanging device is a clear indication to the vehicle driver that the transponder is in said “
inactive-non-responsive”
mode,wherein the non-electronically activated switch is said optical switch located within the transponder, and wherein the non-electronic activator is an element made from an opaque material which is placed at the non-electronic hanging device at a location in which it interrupts the light path at the switch when the interrogator is placed within the non-electronic hanging device, andwherein if said casing is not fully closed, there exists an opening in said casing which at most allows said activator on said non-electronic hanging device to enter the interior of the casing in order to block a said light passage at said non-electronically activated switch.

Abstract
A transponder of an interrogator and toll highway system has a non-electronically activated switch for a first state in which the transponder is in an “active” mode and a second state in which the transponder to be in an “inactive” mode. A non-electronic hanging device hangs the transponder in a vehicle for receiving interrogating signals and a non-electronic activator causes the switch to be in the first state only when the transponder is placed within the hanging device, and to be in an “inactive” mode when the transponder is not placed within the hanging device.

3. In a transponder of an interrogator and toll highway system, wherein the transponder is of a type that enables interaction with an optical switch, and said transponder has an “
- active-responsive”
mode during which the transponder is continuously in standby, while upon receipt of an interrogator signal it responds by sending an identification signal, and an “
inactive-not responsive”
mode during which the transponder does not respond to any interrogation signal, the improvements comprising;a non-electronically activated switch within an essentially closed transponder casing of the transponder having a first state in which it causes the transponder to be in the “
active-responsive”
mode, and a second state in which it causes the transponder to be in the “
inactive-not responsive”
mode;a non-electronic hanging device for receiving the transponder and attaching to a part of a vehicle where the transponder is capable of receiving the interrogator signal coming from a proximate interrogator; and a non-electronic activator on at least one of the transponder and hanging device for causing the non-electronically activated switch to be in the first state only when the transponder is received by the hanging device, therefore, the mere existence of said transponder casing within said hanging device provides to a vehicle driver a clear indication that the transponder is in the “
active-responsive”
mode, while absence of the transponder casing from said hanging device is a clear indication to the vehicle driver that the transponder is in said “
inactive-non-responsive”
modewherein said non-electronically activated switch is said optical switch located within the transponder, and wherein the non-electronic activator is an element made from an opaque material which is placed at the non-electronic hanging device at a location in which it interrupts a light path at the switch when the interrogator is placed within the non-electronic hanging device, and wherein if said casing is not fully closed, there exists an opening in said casing which at most allows said activator on said non-electronic hanging device to enter the interior of the casing in order to block a said light path at said non-electronically activated switch.
