Abstract
This document describes techniques using, and devices embodying, radar-based force sensing. These techniques and devices can enable a great breadth of forces to be measured. Furthermore, radar-based force sensing enables those forces to use, control, and interact with devices.
Claims20
An apparatus comprising:
- a reflective surface configured to:
- deform based on an applied force;
- and
- reflect radar signals;
- and
- a radar-based force-sensing system configured to:
- transmit the radar signals to the reflective surface;
- receive the radar signals reflected by the reflective surface;
- detect the deformation on the reflective surface based on the received radar signals;
- and
- measure a characteristic of the applied force based on the detected deformation.
8 more elements
A method comprising:
- transmitting, with a radar system, radar signals to a reflective surface that is configured to deform based on an applied force;
- receiving, via the radar system, the radar signals reflected from the reflective surface;
- detecting, via the radar system and based on the reflected radar signals, a deformation of the reflective surface, the deformation caused by the applied force;
- and
- measuring a characteristic of the applied force based on the detected deformation.
2 more elements
A method comprising:
- providing a radar field;
- receiving, via the provided radar field, a reflection from a reflective surface having a deformation caused by an applied force;
- detecting, via the received reflections, the deformation on the reflective surface;
- measuring a characteristic of the applied force based on the detected deformation;
- receiving calibration information associated with the applied force;
- and
- mapping the characteristic of the applied force to the calibration information to enable a characteristic of a later-applied force to be associated with the calibration information.
