Abstract: Disclosed is a package delivery mechanism for use by an unmanned aerial vehicle (UAV). The package delivery mechanism includes a gravity activated locking mechanism to lock and unlock a package attached to the UAV based on the weight of the package. When the package is attached to suspension means of the UAV that lowers the package to the ground from the UAV, the locking mechanism automatically engages with the package and keeps the package locked to the suspension means, due to the weight of the package. When the package is lowered and reaches on the ground, the weight of the package is offloaded from the suspension means, which enables the locking mechanism to be disengaged, thereby releasing the package. The package delivery mechanism includes a severing module to sever the suspension means from the UAV.

Abstract: Disclosed are unmanned aerial vehicle (UAV) positioning mechanisms for moving a UAV across a surface. The positioning mechanisms comprise a first guide assembly arranged opposite to a second guide assembly. A drive system is arranged to move the first guide assembly towards the second guide assembly and guide the UAV from a first position to a second position.

Abstract: Disclosed are transportable unmanned aerial vehicle (UAV) facilities. The facilities comprise a housing having an ingress port arranged to receive a payload for delivery by a UAV. The UAV facility is arranged to determine whether the payload corresponds to a delivery consignment based upon a comparison of one or more determined physical characteristics of the payload with one or more expected characteristics of the delivery consignment.

Abstract: Disclosed are unmanned aerial vehicle (UAV) facilities suitable for use by both emergency and non-emergency UAVs. The facilities comprise a housing having first and second moveable platforms. A cover is arranged above the second moveable platform. A drive system operates the first and second moveable platforms and the cover.

Abstract: Disclosed are transportable unmanned aerial vehicle (UAV) facilities. The facilities comprise a housing for holding a UAV, where the housing defines a landing area for the UAV. The facilities also comprise a structure for reducing wind speed across the landing area.

Abstract: A package delivery mechanism (PDM) of an unmanned aerial vehicle (UAV) is described. The PDM includes a gravity activated locking mechanism to lock and unlock a package attached to the UAV based on the weight of the package. When the package is attached to a suspension member of the UAV, the locking mechanism automatically engages with the package and keeps the package locked to the suspension member, due to the weight of the package. When the package is lowered and reaches the ground, the weight of the package is offloaded from the suspension member, which enables the locking mechanism to be disengaged, thereby releasing the package.

Abstract: A thin movement for a stepping motor watch employs a single frame member a peripheral front frame portion surrounding and connected to a back frame portion and stepping motor stator, affixed to the frame member, pins fixed in the back frame portion and stepping motor stator, gear members including the stepping motor rotor and gear train driving the watch hands rotatably mounted on said pins, a dial for the timepiece supported on the front frame portion, the dial serving to control axial movement of the gear members on the pins. Only two layers of gear members are required in the space between the back frame portion and the dial.

Abstract: A magnification lens (12) is disclosed which fits into and is retained in a window (11) in the dial of a calendar wristwatch and is arranged to magnify indicia (10) on a date ring rotatable beneath the window.
