Abstract: Systems, devices and methods are provided to display or otherwise provide addresses in proximity to the device, and to periodically update the addresses as the navigational aid device is transported along a road. The device is adapted to be transported on a road. The device includes a processor and a memory adapted to communicate with the processor. The processor and the memory are adapted to cooperate to provide an address that is proximate to the device. Another aspect includes a method. According to one method embodiment, an address proximate to a navigational aid device is estimated and displayed on the navigational aid device. Other aspects are provided herein.

Abstract: A valve actuator preferably driven by an electric motor is disclosed. The valve actuator is useful with surface safety valves and uses power input from an electric motor to position the valve in its normal position. A mechanism is provided to allow the valve to shift positions to a failsafe position upon failure of electrical power to the motor connected to the actuator. A screw drive is provided with the motor, with a latch mechanism holding a nut against rotation. The nut can advance longitudinally upon rotation of the drive to move a valve stem. Upon failure of electrical power, the latch mechanism releases the nut from a coupling in the actuator which is connected to the valve stem, and the main return springs in the actuator allow the nut to rotate with respect to the screw drive so that the valve can assume its failed position. Normal applications allow the valve to fail closed; however, the valve can be configured so that failure results in opening of the valve if the application requires it.

Abstract: Apparatus for determining the speed and direction of a moving medium such as the atmosphere. The apparatus includes a sensing element which is exposed to the wind to be subjected to forces which displace the sensing element from its rest position. Attached to the sensing element is a dielectric slab which moves in an electric field. The sensing element resides in an equilibrium position determined by the forces applied by the moving medium and those applied by an electric field between the dielectric slab and a set of conductive plates. The displacement of the sensing element is variously determined to indicate the speed and direction of the wind.
