METHOD AND APPARATUS FOR RANGING FINDING, ORIENTING, AND/OR POSITIONING OF SINGLE AND/OR MULTIPLE DEVICES
First Claim
1. A device for conveying a signal for determining a distance traveled by the signal between the device and a receiver, the device comprising a transmitter operable to transmit a series of pulses having a varying pulse strength that varies across the series of pulses in accordance with a designated pulse strength profile.

Abstract
A method and apparatus for ranging finding of signal transmitting devices is provided. The method of signal reception is digitally based only and does not require receivers that are analog measurement devices. Ranging can be achieved using a single pulse emitting device operating in range spaced relation with a minimum of a single signal transmitter and a single digital receiver and processing circuitry. In general a plurality of transmitting pulsed emitters may be ranged and positioned virtually simultaneously in 3-dimensions (XYZ coordinates) using a configuration of a plurality of digital receivers arranged in any fixed 3-dimensional configuration. Applications may involve at least one single transmitter to receiver design to determine range, or at least one transmitted reflecting signal off from an object to determine range.

12. A system comprising:
-
a transmitter operable to transmit a signal formed at least in part by a series of pulses having a pulse strength that varies across said series in accordance with a designated pulse strength profile; a receiver; and a signal processor operatively coupled to said receiver, said signal processor processing received pulses as a function of a received pulse strength profile thereof to output a range value representative of a distance traveled by said series of pulses between said transmitter and said receiver. - View Dependent Claims (13, 14, 15, 16, 17)

18. A signal processor for operative coupling to one or more receivers for processing a transmitted signal received thereby to identify a distance traveled by the transmitted signal, the transmitted signal comprising a series of pulses having a transmitted pulse strength that varies across the series in accordance with a designated pulse strength profile, the signal processor operable to:
-
access a received pulse strength profile of received pulses in said series; identify those of said received pulses having a received pulse strength above a designated threshold; and correlate said identified pulses with a value representative of the distance, said value pre-calibrated as a function of a relative change between said received pulse strength profile and said designated pulse strength profile over distance. - View Dependent Claims (19, 20, 21, 22)

23. A method for identifying a distance traveled by a signal between an emitter and a receiver, comprising:
-
generating a signal formed at least in part by a series of pulses having a pulse strength that varies across said series in accordance with a designated transmission pulse strength profile; transmitting said signal via the emitter; receiving at least a subset of said series of pulses at the receiver; detecting a received pulse strength profile of said received pulses; and correlating said detected pulse strength profile with a distance traveled by the signal between the emitter and the receiver. - View Dependent Claims (24, 25, 26, 27, 28)
