Abstract

A system may include a transmitter and receiver. The system may include an electromagnetic transmission line sensor configured as a passive sensor, configured to determine at least one of a presence of one or more objects or one or more additional sensing parameters, wherein the electromagnetic transmission line sensor is configured as a continuous sensor, wherein the electromagnetic transmission line sensor includes a first port; a second port, wherein one of the first port or the second port comprises the transmitter and another of the first port or the second port comprises the receiver; and a length of waveguide suitable for transmitting an electromagnetic wave, wherein the length of waveguide is configured to couple to auxiliary sensors, wherein the transmitter transmits a packet comprising the electromagnetic wave through the length of waveguide to the receiver, wherein the one or more processing elements of the receiver interprets the packet.

Dependent claims

A system, comprising:

a transmitter;
a receiver, the receiver comprising one or more processing elements;
and
an electromagnetic transmission line sensor, configured to determine at least one of a presence of one or more objects or one or more additional sensing parameters, wherein the electromagnetic transmission line sensor is configured as a passive sensor, wherein the electromagnetic transmission line sensor is configured as a continuous sensor, wherein the electromagnetic transmission line sensor comprises:
a first port;
a second port, wherein one of the first port or the second port comprises the transmitter and another of the first port or the second port comprises the receiver;
and
a length of waveguide disposed between the first port and the second port, wherein the length of waveguide is suitable for transmitting an electromagnetic wave, wherein the length of waveguide is configured to couple to one or more auxiliary sensors, wherein the transmitter transmits a packet comprising the electromagnetic wave through the length of waveguide to the receiver, wherein the one or more processing elements of the receiver interprets the packet to determine the presence of at least one of:
a touch event with the one or more objects, a proximity of the one or more objects, a gesture of the one or more objects, or the one or more additional sensing parameters.

6 more elements

A system, comprising:

an interrogator, the interrogator configured to transmit a launched packet comprising an electromagnetic wave and receive one or more reflected packets corresponding to the launched packet;
and
an electromagnetic transmission line sensor, configured to determine at least one of a presence of one or more objects or one or more additional sensing parameters, wherein the electromagnetic transmission line sensor is configured as a passive sensor, wherein the electromagnetic transmission line sensor is configured as a continuous sensor, wherein the electromagnetic transmission line sensor comprises:
a first port;
a second port, wherein one of the first port or the second port comprises a connection to the interrogator;
and
a length of waveguide disposed between the first port and the second port, wherein the length of waveguide is suitable for transmitting the electromagnetic wave, wherein the length of waveguide is configured to couple to one or more auxiliary sensors, wherein the interrogator transmits a launched packet through the length of waveguide, wherein the one or more reflected packets are caused by a corresponding one or more of one or more objects, the one or more auxiliary sensors, or another of the first port or the second port, wherein the interrogator interprets the packet to determine the presence of at least one of:
a touch event with the one or more objects, a proximity of the one or more objects, a gesture of the one or more objects, a location of the one or more objects, or the one or more additional sensing parameters.
