摘要： A method and system is provided for conducting secure power line carrier communications in full duplex over the power lines of a building. Power line carrier current telephone extension systems utilize 1) a single BASE unit per central office line (for interfacing line carrier signals with the central office line) and 2) one or more EXTENSION units, one for each extension phone set (for interfacing said line carrier signals with said extension phone sets). The method employs system control logic for providing A) multiple extension arbitration logic, B) privacy from eavesdropping and C) security from third party central office line capture by means of a digital messaging system in each base and extension unit utilizing a unique and matching security key (preamble) with each message instructing the system to change operating states, such as, A) during a conversation an extension unit may be put on hold so that a second matching extension can pick up the line, B) a base unit rings matching extension units to signal an incoming call or C) an outgoing call is initiated by a user taking a matching extension phone off hook to access the central office line. Matching of the random security codes may be initiated by the user. By this means unauthorized access to the central office line (especially for long distance calls) and eavesdropping by other users in the same building with similar line carrier telephone extension products is prohibited.

摘要： A method for identifying properties of a downhole electromagnetic network in a downhole tool sting, including the step of providing an electromagnetic path intermediate a first location and a second location on the electromagnetic network. The method further includes the step of providing a receiver at the second location. The receiver includes a known reference. The analog signal includes a set amplitude, a set range of frequencies, and a set rate of change between the frequencies. The method further includes the steps of sending the analog signal, and passively modifying the signal. The analog signal is sent from the first location through the electromagnetic path, and the signal is modified by the properties of the electromagnetic path. The method further includes the step of receiving a modified signal at the second location and comparing the known reference to the modified signal.

Voltage detection circuitry may be intermediate the input voltage source and the activation transistor. An input port may be intermediate and operably connected to the input voltage source and the activation transistor.

The battery-switching transistor is connected to a battery and a power supply node for an electric device. The activation transistor may be configured to activate the battery-switching transistor, enabling voltage from the battery to be available at the power supply node for the electric device. A deactivation transistor is in communication with the battery-switching transistor, and is configured to disrupt power flow from the battery. The transistors may be bipolar junction transistors or metal-oxide semiconductor transistors. The deactivation transistor may be controlled by circuitry from the electric device, enabling the electric device to power itself down.

摘要： A method for triggering an action of at least one downhole device on a downhole network integrated into a downhole tool string synchronized to an event comprises determining latency, sending a latency adjusted signal, and performing the action. The latency is determined between a control device and the at least one downhole device. The latency adjusted signal for triggering an action is sent to the downhole device. The action is performed downhole synchronized to the event. A preferred method for determining latency comprises the steps: a control device sends a first signal to the downhole device; after receiving the signal, the downhole device sends a response signal to the control device; and the control device analyzes the time from sending the signal to receiving the response signal.
