Point of reference displacement and motion sensor
First Claim
1. A sensor module comprising:
- a disc-shaped housing comprising a front end, a rear end opposing said front end, and first and second opposing sides extending between said front end and said rear end, said front end comprising an upper portion being semi-circle-shaped, and a lower portion;
said disc-shaped housing defining a first opening and a second opening spaced apart from said first opening on said upper portion of said front end;
an inertial measurement unit (IMU) sensor carried by the disc-shaped housing;
a wireless transmitter carried by the disc-shaped housing;
a battery power supply carried by the disc-shaped housing; and
an infrared (IR) ranging circuit configured to sense range information for a target and comprising an IR transmitter aligned with the first opening and configured to emit an IR pulse, and an IR photodetector aligned with the second opening and configured to detect a reflected IR pulse;
said wireless transmitter configured to transmit the range information to a remote location.

Abstract
Sensors, devices, systems, devices, and methods for providing wireless modular self-contained units with battery power supply that can use radar, ultrasonic, and IR measuring techniques and sensors for directional detection of impeding objects, persons, or moving targets, and can be used with mobile smart phones and the like. The modular sensor units can be used as a displacement and motion measurement sensor for point of reference measurement applications. The displacement sensing method can use radar, ultrasonic, and IR measuring techniques for directional detection of impeding objects, persons, or moving targets. Upon the detection of the said target, algorithms make use of the direction, angle of ascent, and speed to provide real time position data represented in discrete format. The said sensors are modular in embodiment allowing for multiple sensors to be positioned in strategic regions on the person or system of interest to study the said frame using the method of moments to dissect the object in varying degrees of granularity. The sensor shall connect wirelessly to a mobile handheld (i.e. the end user'"'"'s smartphone) device for real-time data acquisition along with seamless integration into an existing IMU only based system requiring information beyond six degrees of freedom as normally represented by gyros, and accelerometers.
