Abstract: A compression device wearable by a user can apply compression, heat and cold on a left lower limb and a right lower limb of the user. The compression device includes a left massager sleeve, a right massager sleeve, a computing device, a left air pressure hose, and a right air pressure hose. The left massager sleeve and the right massager sleeve surround and secure the left lower limb, and the right lower limb respectively. The computing device generates air pressure. The computing device includes a control panel to control the flow of the air pressure in the left massager sleeve and the right massager sleeve. The left air pressure hose is connected to the left massager sleeve to apply the air pressure to the left lower limb. The right air pressure hose is connected to the right massager sleeve to apply the air pressure to the right lower limb.

Abstract: A compression device wearable by a user can be used to apply compression on one of a left lower limb or a right lower limb of the user. The compression device includes a massager sleeve, a computing device, and an air pressure hose. The massager sleeve is adapted to surround and secure one of the left lower limb or the right lower limb. The massager sleeve includes a heat pad to apply heat to the left knee or the right knee of the user. The computing device generates air pressure. The computing device includes a control panel to control the flow of the air pressure in the massager sleeve. The computing device includes a battery to provide power supply to the control panel. The air pressure hose supplies air pressure to the massager sleeve.

Abstract: There is provided a method for navigation of a drone through a geographical air space, comprising: identifying a drone within or in proximity to a geographical air space; receiving flight data representing a certain flight path through the geographical air space; evaluating the flight data based on a flight risk map to determine the flight risk through the geographical air space, wherein the flight risk map includes zones, each zone being associated with a certain flight safety score; and one or more of: approving the certain flight path when the flight risk of the drone is within an acceptable risk threshold, blocking the certain flight path when the flight risk of the drone is outside the acceptable risk threshold, and obtaining external control of navigation of the drone to navigate the drone through at least one zone having the acceptable risk threshold.
