Abstract:
A vehicle remote control device includes a communications device for transferring vehicle movement control signals to a remote vehicle and a touch-screen interface configured to present a graphical representation of the remote vehicle and to allow a user to manipulate the graphical representation on the touch-screen. A conversion component converts the manipulation of the graphical representation into vehicle control signals for transfer by the communications device.
Abstract:
A one story high building block with the capability of having window or door openings, or a variety of other desirable features; pre-cast within the body of the building block itself. The building block can be colored and stamped or etched to provide an almost endless variety of visual effects. The building block can be connected to a number of other building blocks, each with their own variety of features, to create a dynamic building.

A display device includes a first layer having an optically active display portion, a second layer including a photovoltaic element, and a third layer including electronics operatively coupled to the first layer, wherein the electronics are configured to drive the optically active display portion. Further, the second layer is arranged between the first and third layers.
Abstract:
A method comprises forming elongate structures (5) on a first substrate (3), such that the material composition of each elongate structure (7) varies along its length so as to define first and second physically different sections in the elongate structures. First and second physically different devices (1,2) are then defined in the elongate structures. Alternatively, the first and second physically different sections may be defined in the elongate structures after they have been fabricated. The elongate structures may be encapsulated and transferred to a second substrate (7). The invention provides an improved method for the formation of a circuit structure that requires first and second physically different devices (1,2) to be provided on a common substrate. In particular, only one transfer step is necessary.
Abstract:
A method and apparatus for inspection of the optical quality of a glazing is provided. A greyscale image is generated digitally, and reflected off or transmitted through a glazing, and captured using an image capture device. Preferably, the generation of the greyscale pattern and the capturing of the reflected or transmitted greyscale pattern are synchronised.
Abstract:
An impressed current corrosion protection system comprises a distributed anode in the form of a conductive core (4) covered with a conductive polymeric coating (6) and surrounded by packed coke (8) contained within a polymeric jacket (18). This outer jacket is typically a fabric having a specified resistance to acid conditions and chlorine conditions.
Abstract:
Apparatus whose measurement means consists solely of electronic components, measures the power taken by an electrical load connected to an alternating source of electricity supply in such a manner that the power sensed or energy accumulated is in agreement with the same measurements as performed by a conventional rotating disc electromechanical meter. Fundamental frequency filtering means when applied to either one or both supply voltage and load current ensure that the electronic circuitry performs the appropriate measurements in determining power consumption. A single sample per mains cycle applied to load current and supply voltage is sufficient to measure power consumption, energy consumption accumulation, and produce accumulated energy pulses appropriate to measurement of real power, true power and volt-ampere power consumed by the load. Similar multiphase meters apply the fundamental frequency filtering means to each load current and optionally to each supply voltage to extend the method used in single-phase meters. To improve accuracy of the measurements where an analogue to digital converter is used the current signal, and optionally the supply voltage signal, is perturbed by a Quantisation Error Dispersion (Q.E.D.) signal. Various circuits are described to generate the Q.E.D. signal and the essential properties of the signal are defined.
