Abstract: A photovoltaic (PV) module distribution device may include a platform and an installation arm. The platform may be configured to store a plurality of PV modules in a pre-determined orientation. Each of the PV modules may include solar components that are pre-assembled to form a corresponding PV module. The installation arm may be configured to retrieve a PV module of the plurality of PV modules from the platform. The installation arm may also be configured to position the PV module proximate a support column physically located proximate the PV module distribution device to permit a user to attach the PV module to the support column.

Abstract: A photovoltaic (PV) panel distribution device may include a housing assembly, an elevating system, or a movement mechanism. The housing assembly may store a PV panel in a predetermined orientation within a volume defined by the housing assembly. The elevating system may engage the PV panel to move the PV panel in a direction within the volume so as to position the PV panel in an initial removal position relative to the volume. The movement mechanism may apply a force on the PV panel in the initial removal position to move the PV panel to a final removal position to permit a user to retrieve the PV panel from the final removal position.

Abstract: A method for forming a dye sublimation image in a plastic substrate with a sheet having an image formed thereon of a sublimatic dyestuff is provided. The image on the sheet with a treatment that deposits a silicon compound is placed against a first surface of the substrate. The sheet is heated to a sublimation temperature, which causes the image of the sheet to sublimate into the substrate. The sheet is cooled to a release temperature. The sheet is removed from the substrate.

Abstract: A computer-implemented service is provided to generate a high-resolution digital image data file suitable for creating a large format item in which the digital image is imbued in an object. A user interacts with a configuration application program to determine configuration parameters for the high-resolution digital image data file. A representation (such as a low-resolution image) is displayed, to the user, of what would result if a high-resolution digital representation of an actual scene is adjusted in view of the at least one configuration parameter. Once the user has completed determination of the configuration parameters, the high-resolution digital image data file is generated from digital image data that is the high-resolution digital representation of an actual scene, adjusted in view of the at least one configuration parameter.

Abstract: Method for forming a dye sublimation image in a substrate, particularly a plastic substrate, and apparatus to perform the method. According to the method taught by the present invention, a substrate is disposed on a perforated platen and a dye carrier having an image formed thereon of a dye sublimation ink is disposed on the substrate such that the image is in contact with the substrate. The substrate, dye carrier and at least a portion of the perforated platen are then covered with a flexible membrane. A clamping pressure is then applied to the substrate and the dye carrier through the membrane. Once the clamping pressure is attained, the substrate and dye carrier are first heated, then cooled.

Abstract: A method of operating a variable optical attenuator, including producing an error signal indicative of the product of the reciprocal of the actual input power or actual output power and the difference between the actual output power and the target output power; and controlling the attenuator on the basis of the error signal.

Abstract: A method for forming a dye sublimation image in a substrate with a dye carrier having an image formed thereon of a sublimatic dyestuff is provided. The image of the dye carrier is placed against a first surface of the substrate. The substrate and dye carrier are conveyed along a path with a first part and a second part. A continuous pressure is provided against the first surface of the substrate in the first part and second part of the path and therebetween. The dye carrier is heated to a sublimation temperature in the first part of the path. The dye carrier is then cooled to a depressure temperature in the second part of the path.

Abstract: An optical amplifier comprises a doped fiber and a pump source for providing pump light to the fiber. A power measurement circuit is provided for measuring the output power of the amplifier and a disable circuit is controlled to disable the pump source in response to the output power of an output pulse exceeding a predetermined limit. In this way, power surges can be avoided. Preferably, the predetermined limit takes into account the duration of the output pulse, so that the disable circuit can be tailored to pulse power versus pulse duration standardised limits.

Abstract: An optical amplifier comprises: at least first and second amplifier stages, each stage comprising a doped fiber and a pump source for providing pump light to the fiber. The input and output power of the amplifier is measured to enable automatic gain control. The input and output power is processed in order to derive target pump source levels for achieving a substantially constant gain, and the temporal response of the gain control loop is varied in dependence on the target pump source levels. The response time of the gain control loop is thus matched to the open loop gain of the amplifier, taking into account the combination and settings of the amplifier stages.

Abstract: An optical amplifier comprises a pumped doped fiber with a power measurement circuit for measuring the input and output power of the amplifier. Automatic gain control is implemented, and the calculation of output power for the AGC loop takes into consideration the temperature provided by a temperature measurement device. This enables a flatter gain response to be achieved over varying input power, which enables an increase in the dynamic range of the amplifier and thereby a possible increase in system capacity of a WDM system using the amplifier.
