Abstract: A process for manufacturing a cadmium telluride based thin film photovoltaic device having an intermixed layer is provided. The process can include introducing a substrate into a deposition chamber, wherein a window layer (e.g., a cadmium sulfide layer) is on a surface of the substrate. A sulfur-containing gas can be supplied to the deposition chamber. In addition, a source vapor can be supplied to the deposition chamber, wherein the source material comprises cadmium telluride. The sulfur-containing gas and the source vapor can be present within the deposition chamber to form an intermixed layer on the window layer. In one particular embodiment, for example, the intermixed layer generally can have an increasing tellurium concentration and decreasing sulfur concentration extending away from the window layer.An apparatus for sequential deposition of an intermixed thin film layer and a sublimated source material on a photovoltaic (PV) module substrate is also provided.

Abstract: Techniques for improving linearity of amplifiers are described. In an exemplary design, an amplifier (e.g., a power amplifier) may include a plurality of transistors coupled in a stack and at least one diode. The plurality of transistors may receive and amplify an input signal and provide an output signal. The at least one diode may be operatively coupled to at least one transistor in the stack. Each diode may provide a variable bias voltage to an associated transistor in the stack. Each diode may have a lower voltage drop across the diode at high input power and may provide a higher bias voltage to the associated transistor at high input power. The at least one transistor may have higher gain at high input power due to the higher bias voltage from the at least one diode. The higher gain may improve the linearity of the amplifier.

Abstract: Exemplary techniques for performing impedance matching are described. In an exemplary embodiment, the apparatus may include an amplifier (e.g., a power amplifier) coupled to first and second matching circuits. The first matching circuit may include multiple stages coupled to a first node and may provide input impedance matching for the amplifier. The second matching circuit may include multiple stages coupled to a second node and may provide output impedance matching for the amplifier. At least one switch may be coupled between the first and second nodes and may bypass or select the amplifier. The first and second nodes may have a common impedance. The apparatus may further include a second amplifier coupled in parallel with the amplifier and further to the matching circuits. The second matching circuit may include a first input stage coupled to the amplifier, a second input stage coupled to the second amplifier, and a second stage coupled to the two input stages via switches.

Abstract: A vending machine capable of refilling used ink cartridges as well as dispensing filled ink cartridges is closed. The vending machine includes at least one cartridge receptacle for receiving an ink cartridge, a user interface, a display unit, a nozzle health check module, a printhead servicing module, an ink reservoir, an ink refilling unit, a compartment containing new ink cartridges, a compartment containing filled, second-hand ink cartridges, and a recycle compartment for receiving discarded ink cartridges. The user is presented by the display unit with the option of (a) refilling a used cartridge, (b) purchasing a filled cartridge, or (c) returning a used cartridge in exchange for a purchase rebate or a discount voucher. When the user selects the option of refilling, the vending machine executes a refilling subroutine which includes checking the nozzle health.

Abstract: The present invention provides a method and system for automatic objects classification. The method comprises: acquiring a set of objects; classifying the objects based on query log to generate a first classification result; classifying the objects based on ontological information to generate a second classification result; and semantically fusing the first and second classification results to generate a final classification result. According to the present invention, compared with the prior arts, by semantically fusing the query log-based classification result and the ontology-based classification result, the accuracy and user-friendness of the object classification can be improved.
