Abstract: A drone equipped with fuel cell power pack capable of reducing weight by supplying power from a fuel cell while enabling long-term operation of a drone is provided. The drone equipped with fuel cell power pack may include a case including a wing part placed along an outer circumference of the case, a module frame placed in the case, a fuel cell unit placed in the module frame with a weight balance; and a gas tank mounted on the module frame and connected to the fuel cell unit. Because an overall weight balance of the fuel cell power pack itself can be maintained, even if it is integrally mounted inside the drone, the stable operation of the drone can be achieved.

Abstract: A fuel cell power pack is provided. The fuel cell power pack may include a case, a gas tank placed in a gas tank mounting and removing part formed in the case, and a fuel cell unit placed in the case in a weight balance with the gas tank. According to the fuel cell power pack, it is possible to reduce weight by supplying power from a fuel cell while enabling long-term operation of a flying object such as a drone, to maintain an overall weight balance and achieve a stable operation of the drone, even if integrally mounted in the drone, to maintain a stable operating environment temperature of a stack by improving an air circulation structure, and to enhance the user's convenience with a gas supply structure that is easy to attach and detach the gas tank.

Abstract: A multicopter is provided. The multicopter may include a main body part, a wing part having one end connected to the main body part, and the other end connected to a propeller assembly, and a foldable part disposed on the wing part to fold the wing part, wherein the wing part is located above the main body part with respect to a Z-axis.

Abstract: Weighing apparatus preferably comprises at least two weight sensing elements that are connected to each other by at least one communication cable. In accordance with this invention, weight sensing elements are preferably positioned either adjacent to or at each end of bed in order to support bed. In a preferred embodiment, each weight sensing element comprises a weight sensing base and at least a pair of mounting assemblies that may be at or adjacent to the head and foot of bed. Preferably, weight sensing base extends laterally and mounting assemblies extend vertically. Each weight sensing base is supported by the corresponding pair of mounting assemblies. In addition, a power cord is used for transferring electrical power to weighing apparatus. A pendant assembly is used for operating weighing apparatus. A pendant cord connects hand-held pendant to both weight sensing elements upon being plugged into either weight sensing element.
