A device for two-way detection of the approach of a portable apparatus for near-field hands-free access to a vehicle, said device including a communication antenna having a near-field communication frequency, the device including: a first passive inductive sensor oriented towards the outside of the vehicle, a second passive inductive sensor oriented towards the inside of the vehicle, the two sensors being arranged so as to face one another, separated by a ferrite, and receiving the electromagnetic field emitted by the communication antenna, and being capable of detecting the approach of the portable apparatus; a device for measuring a first voltage across the terminals of the first sensor and a device for measuring a second voltage across the terminals of the second sensor; a device for comparing the first voltage and the second voltage in order to detect the approach of the portable apparatus coming from outside or coming from inside the vehicle.

Embodiments relate to a security system for securing items within any cavity, of any object, which may be opened or closed with a zipper. The security system includes functionality to detect the opening and/or detect the closing of a zipper. The security system may be configured to trigger an alarm if the zipper is opened while the security system is in an armed state. The security system may be configured to not trigger the alarm if the zipper is opened while the security system is in a disarmed state. The security system may be armed and/or disarmed via a wireless signal.

An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry. Audit trail data may be recorded based on usage of the key.

An induction type padlock includes a shell, a lock bolt, a shackle, a driving unit, a light-emitting component, and an induction control unit. The lock bolt slides in the shell and has a recess. The shackle is inserted into the shell through the lock bolt and has a latch portion being able to be latched by the lock bolt. The driving unit rotates the position limiter in the recess; the position limiter has a wide portion and a narrow portion. The induction control unit is electrically connected to the driving unit and the light-emitting component. The induction control unit senses a signal to select the wide or the narrow portion of the position limiter to be disposed in the recess and controls the light-emitting component. Therefore, the time delay problems of unlocking and locking can be solved and the distinguishable lighting indications of unlocking and locking can be obtained.

A mobile computing device for transmitting token data to a key card reading device having an activation mechanism is provided. The computing device is programmed to receive token data representing access data of a key card, generate a transmission signal representing the access data of the key card based on the token data in response to receiving the token data, and output the transmission signal to the key card reading device. The access data causes the key card reading device to activate the activation mechanism. The transmission signal causes the key card reading device to activate the activation mechanism when the mobile computing device is placed near the key card reading device and the transmission signal is authenticated by the key card reading device.

This invention relates to a transponder key testing device and to a method of testing a transponder key. The transponder key may be used with any article using transponder key technology, typically a motor vehicle. The transponder key testing device has a first memory (30) in which is stored data relating to an article signal emitted by each one of a number of articles (10) and a second memory (32) in which is stored data relating to a response signal emitted by each one of a number of transponder keys (20). The testing device has a receiver (24) adapted to receive the article signal and the response signal. The testing device compares the article signal with data in the first memory, compares the response signal with data in the second memory, and determines whether or not the transponder key (20) is compatible with the article (10). There is also provided a method of testing a transponder key for compatibility with a particular article.

An intelligent authentication system including an electronic lock and an electronic key is provided. The electronic key includes an electronic paper display apparatus. The electronic key is adapted to perform a two-step authentication with the electronic lock. The two-step authentication includes the first authentication step and the second authentication step. The electronic paper display apparatus is driven after the first authentication step is passed. And during the second authentication step, the electronic key performs an authentication operation with the electronic lock by using the driven electronic paper display apparatus. Furthermore, an electronic key for the foregoing intelligent authentication system is also provided.
