摘要:
A lock programmer/interrogator assembly for communicating with an electronic lock. The assembly includes a key comprising a circuit card having surface contacts positioned to align with contacts in an electronic lock smart card reader when the key is inserted into a smart card reader module. A cable connector is mounted on the circuit card. The circuit card includes current paths that electrically connect the surface contacts to pins of the cable connector. The assembly also includes a cable connectable at a first end to the cable connector and at a second end to a computer. The cable includes wires connectable between the pins of the cable connector and the computer.

A method for tracking user access to electronic mortise locksets includes providing electronic mortise locksets that each include a locking bolt that a lock-out mechanism blocks against retraction until a lockset controller disengages the lock-out mechanism in response to a key reader identifying a properly configured key. Each lockset controller is programmed to upload access data to a key memory whenever a properly configured key is used to unlock the electronic mortise lockset by inserting the key into a key reader of the lockset. The access data stored in the key memory includes a record of the times that the key is inserted into each of the locksets.

A lockset controller that functions in either a low power sleep mode or an active mode and includes a processor that's inactive in the sleep mode and active in the active mode. A wakeup control module switches the controller from the sleep mode to the active mode when a wakeup event occurs. A key card control module acts as an interface between a key card reader and the controller such that electronic data may be transferred between the two devices. A motor driver module drives an electrical motor that moves a locking mechanism component of the lockset apparatus between locked and unlocked states. The controller switches from sleep to active mode when the processor receives a wakeup signal. Once in active mode, if the processor receives an authorized data signal, the processor transmits a power signal that causes the electrical motor to unlock the locking mechanism.

A method and apparatus for remotely and selectively controlling and altering fluid flow through tubular string disposed within a wellbore and further control fluid flow between the tubular string inner flow passage and the annular flow passage, and a method for selectively and remotely receiving and interpreting a form of command or information at a particular apparatus within the wellbore caused by the operator on earth surface through a change of a physical property of the environment. The apparatus comprising a body, a valve operable in plurality of states, an actuator, and an activator responsive to a change of a physical property of the environment caused by the operator on earth surface.

A key card encoder incorporates a plunger that is pushed downward as the card is manually inserted into a slot in the encoder and a potentiometer whose value changes based on the plunger position to indicate the card's position at all times. As the card is inserted into the slot, a head encodes a magnetic strip on the card as the card is inserted into the slot, while the head verifies the code in the reverse direction as the card is withdrawn from the slot. The slot is illuminated in different colors and flashing patterns to guide the user through the encoding process and notify the user if there is an encoding error.

The present invention discloses a method and apparatus for remotely and selectively control fluid flow through tubular string disposed within a wellbore and further control fluid flow between the tubular string inner flow passage and the annular flow passage. The present invention further discloses a method of selectively and remotely receiving and interpreting a form of command or information at a desired apparatus within the wellbore caused by the operator on earth surface.
摘要:
A method of communicating between electronic door locks, access point hubs and a central controller includes the steps of transmitting a probe signal from a central controller, or access point hub receiver to the electric door lock in several different frequencies. Transmission between the locks stations and the access point hub are then synchronized to accommodate multiple lock stations and to prevent overlapping transmissions.
