  • Patent number: 9381777
    Abstract: A signal transponder transceiving signals using different communication protocols has a control module, a receiving module and a transmitting module. The control module is electrically connected to the receiving module and the transmitting module, is built in with multiple communication protocols, decodes a tire pressure signal transmitted from and encoded by an external tire pressure sensor with one of the communication protocols, encodes the decoded information to a new tire pressure signal, and further transmits the new tire pressure signal to a tire pressure receiver. Accordingly, there is no failure in decoding and transmissions and cost increase when the signal transponder communicates with tire pressure sensors and a tire pressure receiver using two different communication protocols.

  • Patent number: 9308783
    Abstract: The tire pressure monitoring device has a storage module, a receiver module and a control module. The tire pressure monitoring device retrieves a protocol by external indication or internal discrimination. The external indication is that the control module retrieves a protocol from the storage module according to an external signal, and then the control module compares the retrieved protocol with a protocol of a tire pressure signal received by the receiver module. If a comparison of the protocols matches, the tire pressure monitoring device decodes the tire pressure signal. The internal discrimination is that the control module compares different protocols stored in the storage module with a protocol of the tire pressure signal. If a comparison of the protocols matches, the tire pressure monitoring device decodes the tire pressure signal.

  • Publication number: 20090190805
    Abstract: A fingerprint recognition system for an electronic device includes an input module, a computational module, and a database. The input module receives initial and subsequent fingerprint templates, and a unique character code. The computational module calculates a unique key for the initial fingerprint template on the basis of the character code to establish security, and a check key for the subsequent fingerprint template on the basis of the character code. The computational module removes the security for the electronic device when the check key matches the unique key. The database stores the initial fingerprint template and the unique key. An electronic device including the fingerprint recognition system, and a fingerprint recognition method are also disclosed.

    Abstract: Disclosed is a cockroach-trap mainly including a box having a top cover and a bottom tray pivotally hinged together, a metal net spread over inner surfaces of the box and being formed by alternately and densely arranging conductors of different polarities, and an intermittent-high-voltage generating circuit electrically connected to two conductors extended from the metal net. The box is provided with at least one entrance which is not covered by the metal net. When the box is closed, two pin holes separately provided on the top cover and the bottom tray opposite to the hinges together form a socket to receive a plug connected to a power source, so that power can be supplied to the intermittent-high-voltage generating circuit for the circuit to generate intermittent high voltage on the metal net. Cockroaches entering into the closed box can be killed by the high voltage.
