20110132680 | ANTITHEFT APPARATUS FOR EQUIPMENT WITH PRIME MOVER - In an apparatus for preventing theft of equipment (electric wheelchair) having a prime mover (electric motor), a prime mover controller, and an authenticator that acquires ID information from an electronic key when the key is brought close thereto by an operator, determines whether the acquired ID information corresponds with authentication ID information, and permits the controller to start the prime mover when the acquired ID information is determined to correspond with authentication ID information, the controller stores operating history of the equipment, and the authenticator acquires the history from the controller when the key is brought close thereto and transmits the acquired history to the key when the key is brought close thereto, thereby making it easy to acquire the operating history of the equipment. | 06-09-2011 |
20110133550 | ANTITHEFT APPARATUS FOR EQUIPMENT WITH PRIME MOVER - In an apparatus for preventing theft of equipment (electric motor) having a prime mover (motor), a prime mover controller, a starter switch that allows the operator to connect/disconnect power from a power source to the prime mover; and an authenticator that acquires ID information from an electronic key through a receiver when the key is brought close thereto by the operator, and permits the controller to start the prime mover when acquired ID information is determined to correspond with authentication ID information, the starter switch is made of electrode pair that is sensitive to electrostatic capacitance, and the starter switch and the receiver are installed together on an electronic circuit board, thereby achieving the smaller structure of the apparatus. | 06-09-2011 |
20110133911 | ANTITHEFT APPARATUS FOR EQUIPMENT WITH PRIME MOVER - In an apparatus for preventing theft of equipment having a prime mover, an prime mover controller, and an authenticator that acquires ID information from an electronic key when the key is brought close thereto by an operator, and permits the prime mover controller to start the prime mover when the acquired ID information is determined to correspond with authentication ID information, data indicating a number of times the key is updated is included in the ID information, and the authenticator determines whether the number of times indicated in the data is greater than that in the authentication ID information, and when the number of times indicated in the data is greater than that in the authentication ID information, updates the authentication ID information such that it is equal to the number of times indicated in the data, thereby enabling to easily update authentication ID information of the equipment. | 06-09-2011 |
