A system and method for combining power from DC power sources. Each power source is coupled to a converter. Each converter converts input power to output power by monitoring and maintaining the input power at a maximum power point. Substantially all input power is converted to the output power, and the controlling is performed by allowing output voltage of the converter to vary. The converters are coupled in series. An inverter is connected in parallel with the series connection of the converters and inverts a DC input to the inverter from the converters into an AC output. The inverter maintains the voltage at the inverter input at a desirable voltage by varying the amount of the series current drawn from the converters. The series current and the output power of the converters, determine the output voltage at each converter.

A system for producing an assembly comprising at least one component includes at least one 3D metrology system, a workstation processing element, numerical control apparatus and a flexible work cell. The metrology system maps the components for use by the workstation processing element, which electronically displays three-dimensional authority models representative of the components.

The workstation processing element then commands the numerical control apparatus to perform a machine operation on the components based upon the comparison. As the numerical control apparatus performs the machine operation on the components, the workstation processing element dynamically displays the actual models such that the electronic display of the actual models is automatically and repeatedly updated.

The purpose of this invention is to increase reliability of a switching element while reducing consumption power. In the vertical blanking period, an end pulse signal (ED) changes from the low level to the high level. The potential of first nodes (N1) in the first stage to (m−1)th stage of cascade-connected m-stage bistable circuits included in a shift register of the scanning signal drive circuit is reliably maintained at the low level, and the potential of second nodes (N2) in the first stage to the (m−1)th stage changes from the high level to the low level. In a bistable circuit in the m-th stage, the potential of the first node (N1) in the m-th stage changes from the high level to the low level, and the potential of the second node (N2) in the m-th stage is maintained at the low level. The supply to a bistable circuit of clock signals (CKA, CKB) is stopped. Until a write period in the subsequent vertical scanning period, the potential of the first node (N1) and the potential of the second node (N2) in each stage are maintained at the low level.

An inter-layer insulating film and a gate insulating film which are positioned on the optical path of light from an organic EL element to be externally emitted, for example, located under a transparent electrode, are removed. Because SiO₂ films having a refractive index which differs significantly from refractive indexes of other films are used for these films, there was a problem of light attenuation in these layers. Such light attenuation can be reduced by removing these layers located in the region through which light from the organic EL element passes.

Moreover, since it is possible to lower a voltage of a timing pulse supplied by the driver circuit, a booster circuit can be omitted, and reduction of an area of the driver circuit can be realized.

The apparatus of the present invention are directed to an selectively accessible electromagnetically resonant data storage element (implemented as a resonant tag, card, and/or embedded element), that is selectively responsive to predetermined electromagnetic interrogation thereof, that comprises a novel membrane switch component for enabling a user to selectively enable and/or disable interrogatory access to the resonant component, to protect from unauthorized interrogation thereof (hereinafter “MSRDS element”). The inventive MSRDS element comprises a top circuitry layer, a bottom circuitry layer, which includes a microchip, a plurality of contact pads and an antenna, an insulation spacer layer, a pressure layer retention component, and an optional EM/EMI shielding layer. The membrane switch may be formed through a combination of aligned and configured subcomponents of at least a portion of the element's layers. In one embodiment thereof, the pressure layer retention component may be advantageously utilized to maintain the membrane switch in a pressed down position to thereby enable the MSRDS element to function continuously (i.e., in an Always-ON security mode), until such time that the pressure layer retention component is removed. In this exemplary embodiment of the MSRDS element, for example used in conjunction with consumer products, when a consumer purchases a product that has been provided with the MSRDS element, they remove (e.g., peel off, etc.) the pressure layer retention component to change the element to an Always-OFF security mode, such that the MSRDS element is only accessible to electromagnetic interrogation thereof when the membrane switch is held down. Therefore, the MSRDS element of the present invention provides a greater level of data security advantageously balanced with convenience—it is freely accessible prior to acquisition thereof by a user, and is thereafter easily made secure by the user, who is provided with the capability of readily and selectively enabling access to the data stored therein.
