Abstract
A method (e.g., a method for measuring a separation distance to a target object) includes transmitting an electromagnetic first transmitted signal from a transmitting antenna toward a target object that is a separated from the transmitting antenna by a separation distance. The first transmitted signal includes a first transmit pattern representative of a first sequence of digital bits. The method also includes receiving a first echo of the first transmitted signal that is reflected off the target object, converting the first echo into a first digitized echo signal, and comparing a first receive pattern representative of a second sequence of digital bits to the first digitized echo signal to determine a time of flight of the first transmitted signal and the echo.
Claims21
A device comprising:
- a housing hosting a processor, a memory, a receiver, a transmitter, and at least one of a display or a speaker, wherein the processor is in communication with the memory, the receiver, the transmitter, and the at least one of the display or the speaker, wherein the memory stores a set of instructions executable via the processor, wherein the set of instructions instructs the processor to:
- cause a signal to be sent via the transmitter,
- cause an echo to be received via the receiver, wherein the echo is based on the signal reflecting off an object, wherein the echo includes a digital value,
- decode the digital value such that a decoding is formed,
- determine a time of flight of the signal based on the decoding,
- generate a distance value based on the time of flight,
- determine a position of the housing based on the distance value, wherein the position is relative to the object, and
- take an action based on the position, wherein the action includes an output, wherein the output is via the at least one of the display or the speaker.
A system comprising:
- a defined area including a plurality of distance sensors that are able to receive signals from each other;
- and
- a processor in communication with the distance sensors, wherein the processor is programmed to:
- receive a plurality of readings from the distance sensors based on an object positioned within the defined area,
- determine a position of the object within the defined area based on the readings, and
- take an action based on the position.
