Abstract: Disclosed is a technique for landing a drone using a parachute. The technique includes a parachute deployment system (PDS) that can deploy a parachute installed in a drone and land the drone safely. The parachute may be deployed automatically, e.g., in response to a variety of failures such as a free fall, or manually from a base unit operated by a remote user. For example, the PDS can determine the failure of the drone based on data obtained from an accelerometer, a gyroscope, a magnetometer and a barometer of the drone and automatically deploy the parachute if any failure is determined. In another example, the remote user can “kill” the drone, that is, cut off the power supply to the drone and deploy the parachute by activating an onboard “kill” switch from the base unit.

Abstract: A system for formulating a performance metric of a motion such as water sport motion, preferable a swimming stroke, includes a wearable sensor device including 4 pressure sensors, a 9 degrees of freedom inertial measurement unit (IMU), a micro-processor communicating with the pressure sensors and the IMU, and waterproof housing in the form of a flexible silicone band to house the microprocessor, the pressure sensors and the IMU. The system includes an external computer communicating with the device for receiving and combining input data from each of the pressure sensors and the IMU, via the microprocessor, and a processing unit configured to combine the input data from both the at least one pressure sensor and the IMU. The input data is used to infer at least one force magnitude and at least one force direction, the input data being used to provide the performance metric of the water sport motion.
