Abstract

A sensing system includes a sensor, a wireless transmission system, a wireless receiver system, and a controller. The sensor is configured to determine sensor data, the sensor data associated with a sensing environment. The wireless transmission system is configured to wirelessly couple with the sensor, the wireless transmission system configured for wirelessly providing significant electrical energy to the sensor as wireless power signals and receive the sensor data as in-band data signals encoded in the wireless power signals. The wireless receiver system is operatively associated with the sensor and with which the wireless transmission system couples with the sensor and is configured to receive the significant electrical energy as the wireless power signals from the wireless transmission system. The controller is operatively associated with the wireless transmission system and is configured to decode the in-band signals from the wireless power signals as the sensor data.

Dependent claims

A sensing system comprising:

a wireless transmission system that is configured to:
generate an alternating electromagnetic field for delivering wireless power;
detect a change in the alternating electromagnetic field that is representative of an in-band data signal;
and
decode the in-band data signal to retrieve embedded data from the in-band data signal;
one or more sensors that are configured to determine sensor data at a first location;
and
a wireless receiver system that is (i) in a wired electrical connection with the one or more sensors, (ii) proximate to the first location, and (iii) configured to:
receive the wireless power as delivered via the alternating electromagnetic field;
receive the sensor data from the one or more sensors;
encode the sensor data as the embedded data for the in-band data signal;
and
modify the alternating electromagnetic field thereby causing the change in the alternating electromagnetic field that is representative of the in-band data signal,
wherein the wireless transmission system is positioned proximate to a second location that is separated from the first location by a separation gap, and
wherein one or more intermediary objects are positioned within the separation gap.

A method of operating a sensing system, the sensing system comprising (i) one or more sensors, (ii) a wireless receiver system in a wired electrical connection with the one or more sensors, and (iii) a wireless transmission system, the method comprising:

generating, via the wireless transmission system, an alternating electromagnetic field that is configured to deliver wireless power to the wireless receiver system, thereby powering the wireless receiver system and the one or more sensors;
determining, via the one or more sensors, sensor data associated with a first location that is separated from the wireless transmission system by a separation gap between the first location and a second location that is proximate to the wireless transmission system, wherein one or more intermediary objects are positioned within the separation gap;
using the wireless receiver system:
encoding the sensor data as embedded data for an in-band data signal;
and
modifying the alternating electromagnetic field thereby causing a change in the alternating electromagnetic field that is representative of the in-band data signal;
and
using the wireless transmission system:
detecting the change in the alternating electromagnetic field that is representative of the in-band data signal;
and
decoding the in-band data signal to retrieve embedded data from the in-band data signal, wherein the embedded data is representative of the sensor data.
