    摘要: Methods and apparatuses for reducing dark current and hot pixels in CMOS image sensors. A pixel apparatus includes a photosensor capable of generating dark current, a floating diffusion region coupled to the photosensor by way of a charge transfer transistor, a rest transistor connected between the floating diffusion region and an array pixel supply voltage. The array supply voltage varies between first and second voltages when sampling pixel signals from the pixel.

    摘要: Methods and apparatuses using four-way-shared readout circuits to increase pixel fill factor. Embodiments consolidate circuits from several pixels, reducing the number of components in each pixel and this increasing the fill factor of each pixel. Additionally, embodiments use “straight gate” transfer gates to increase the readout speed and symmetry of the smaller pixels.

    摘要: Web workflow service information may include implementations, contracts, addresses, bindings, and other information that is sprinkled throughout source files, configuration files, and other locations. A service explorer extracts service information, and visualizes service information in a form that supports navigation, thereby helping developers understand and use workflow service information. A workflow service structure underlying the visualization is constructed with the extracted service information. A hierarchical node visualization of the service structure is displayed in a service explorer GUI. A developer navigates by expanding/contracting nodes, searching nodes, selecting nodes, and running tools with node-specific information, e.g., for testing, tracing, publication, workflow design, and so on. The visualization is automatically updated after service configuration changes. Node-specific source code is displayed for contract and implementation classes, and pertinent sections of configuration files are displayed for bindings and addresses. Derivation of endpoints, bindings, and addresses are displayed for implicitly set endpoints.
