Abstract: An autonomous remote device for deployment in an area, comprising: a mechanism for launching the device airborne from a first of a plurality of locations; a mechanism for navigating the device when airborne to a second of the plurality of locations; and a mechanism for landing the device at the second of the plurality of locations.

Abstract: An aerial device (100) capable of controlled flight has a body (110), a rotor (120) arranged to rotate relative to the body; and a deployable sheet (130), the sheet having an undeployed configuration in which the sheet is folded against the body and a deployed configuration in which the sheet is at least partially unfolded away from the body.

Abstract: A robotic vehicle has legs and propellers to enable it to walk, fly, and or swim.

Abstract: There is provided a method of using a device capable of controlled flight in a surrounding environment, the device comprising: lifting means for providing lift to the device; object-retaining means for holding an object to be affixed to a target site; and a dispensing assembly for dispensing an adhesive, wherein the method comprises: controlling the lifting means so as to controllably fly the device in the surrounding environment; and using the device to affix an object held by the object-retaining means to a target site in the surrounding environment by dispensing an adhesive from the dispensing assembly. Thus, an aerial device, for example a robotic device, may be used to fly to a desired location and affix an object at the desired location, by dispensing, ejecting or otherwise applying an adhesive.

Abstract: A window assembly with a safety catch comprises a manually movable window sash which normally slides between a raised and a fully lowered position within a surrounding window frame. A weight is connected to the sash by a cable which counter-balances weight of the sash. The safety catch prevents downward falling of the sash to the fully lowered position in the event of breakage of the cable. The safety catch comprises a sash block spaced below the weight and clear of the sash when the cable is intact and the weight is positioned to fall if released from the sash to move the sash block to a blocking position which holds the sash above its fully lowered position.
