摘要： A remote locator (RL) continuously transmits multi-frame pings in a slow ping mode. The user activates a transponder/micro-transponder (MT) to receive at least a portion of the multi-frame ping and transmits a reply to the RL. The RL calculates a distance between the RL and the MT using the time-of-flight between the transmission of the ping and the receipt of the corresponding reply. The RL continues to send pings to the MT, where the ping includes distance measurements encoded therein. The user initiates sending a message from the MT to the RL to change to a fast ping mode, where the RL transmits pings at an increased rate. The MT includes a compass to captures readings while receiving and replying to pings. The MT determines a directional location for the RL with the collected measurements and received information and can provide a distance and directional readout to the user.

摘要： A facsimile system is explained on the basis of a single unit which is connected to a video pick-up device and to a facsimile reconstruction device. The video signal is converted into a two level signal and the lengths of runs of the same level are metered by counting increments of such run lengths and converted the count numbers into a stream of ternary digits to distinguish length numbers for the runs of different signal levels by digit notation. These ternary encoded run length numbers pass through a buffer for storage on tape. Upon retrieval they pass again through the buffer and are converted in groups of one or two ternary digits into seven symbols, used to phase and amplitude modulate a carrier for transmission. Carrier signals when received are demodulated and converted into ternary code signals, which are buffered and stored. Upon image reconstruction, the stored, ternary encoded run length numbers are retrieved, pass through the buffer and are used to re-establish a two level signal. The system and method as such is usable for data compression of any type of two level source signals.

摘要： Described is a system and method for providing a synchronization pattern in a communication system. The method includes generating a synchronization pattern with good randomness properties; packing a signal for transmission with m headers, each header consisting of the synchronization pattern 1/m symbol-time shifted from the previous header; and transmitting the signal. A further method provides for the sampling the transmitted signal with m headers of symbol-time shifted synchronization patterns; and determining symbol timing offset by computing and reordering correlation peaks from the synchronization patterns. A system includes a transmitting system, a receiving system, and a data channel. The transmitted signal includes m headers with 1/m symbol-time shifted synchronization patterns. The receiving system undersamples the transmitted signal with m synchronization patterns to simulate an oversampled synchronization pattern.

摘要： The location of a transponder or micro-transponder (MT) device can be determined relative to a remote locator (RL) device. The RL transmits a multi-frame ping to the MT when initiated by a user. The MT receives the multi-frame ping, and transmits a multi-frame reply that can be hollowed out to conserve transmit power and reduce interference between devices. The RL calculates a distance between the RL and the MT using the time-of-flight (TOF) between the transmission of a ping and the receipt of a reply. The user designates one or more threshold ranges for the MT relative to the RL. The RL provides a user alert whenever the MT travels outside a threshold range. Alerts can be provided through a number of mechanisms including an audible alert, a visible alert, a vibrating alert, an email message, an SMS message, an instant message, a pager message, a telephone call, etc.

摘要： A hand-held remote locator (RL) device is used to locate a transponder or micro-transponder (MT). The user activates the RL to transmit a multi-frame ping to the MT in a slow ping mode, where the MT transmits reply messages when the multi-frame ping is received The RL calculates a distance between the RL and the MT using the time-of-flight (TOF) between the transmission of a ping and the receipt of a reply. The user can then engage a fast ping mode, where the RL transmits the multi-frame ping at an increased rate. The user then extends the RL device away from their body and turns through at least a partial arc length about their center line such that data is collected including compass readings, Doppler information, and distance calculations. The directional location for the MT is determined by the RL using the collected data.
