  • Patent number: 8352775
    Abstract: A computer readable storage medium with executable instructions specifies the execution of a state machine operating across a set of computing nodes in a distributed computing system. The executable instructions execute a set of operators, where the execution of each operator is under the control of a state machine that periodically invokes pause control states to pause the execution of an operator in response to a violation of a service level agreement specifying an operating condition threshold within the distributed computing system. Partitions of input data are formed that are worked on independently within the distributed computing system. A set of data batches associated with the input data is processed. Data partition control states to process the partitions associated with the set of data batches are specified. Key control states to process a set of keys associated with a data partition of the partitions are defined.

  • Patent number: 8348251
    Abstract: A sewing clip is provided. In one embodiment, the sewing clip securely clamps fabrics of various thicknesses, sizes, elasticity, and textures in assistance of a sewing operation. The sewing clip includes two rigid members and an elastic assembly. The two rigid members each have a first surface with a clamping and handling end and a hinge extension coupled to the first surface. When employed in a sewing operation, the clamping end of each rigid member has a tapering-width adapted to slide in a direction away from a stitching point. An elastic assembly couples the hinge extensions of each rigid member and biases the two rigid members so as to secure overlapping fabric between the clamping ends while avoiding unnecessary alteration or damage to the fabric. A recessed divot is also provided in the clamping end that allows for retention of surplus fabric.

  • Patent number: 8352954
    Abstract: A resource allocation system begins with an ordered plan for matching requests to resources that is sorted by priority. The resource allocation system optimizes the plan by determining those requests in the plan that will fail if performed. The resource allocation system removes or defers the determined requests. In addition, when a request that is performed fails, the resource allocation system may remove requests that require similar resources from the plan. Moreover, when resources are released by a request, the resource allocation system may place the resources in a temporary holding area until the resource allocation returns to the top of the ordered plan so that lower priority requests that are lower in the plan do not take resources that are needed by waiting higher priority requests higher in the plan.

  • Patent number: 8349866
    Abstract: The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of 1H-imidazo[4,5-c]quinolin-4-amines and 1H-imidazo[4,5-c]quinolin-4-amine-related compounds, which are capable of crossing biological barriers with high penetration efficiency. The HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

  • Patent number: 8347030
    Abstract: A control arrangement, for example, in a digital component that forms part of a system, draws an input current for its operation and is configured for monitoring an interface for any one of a group of commands and, upon detecting an issued one of the group of commands, operates the component for executing the issued command in an operational mode, and during an idle time on the interface, the control arrangement exclusively monitors the interface for any one of the group of commands such that the input current is limited to a leakage current. The component may draw less than 1 milliamp of current during the idle mode.

  • Patent number: 8346567
    Abstract: Methods, devices, and computer program products enable the embedding of forensic marks in a host content that is in compressed domain. These and other features are achieved by preprocessing of a host content to provide a plurality of host content versions with different embedded watermarks that are subsequently compressed. A host content may then be efficiently marked with forensic marks in response to a request for such content. The marking process is conducted in compressed domain, thus reducing the computational burden of decompressing and re-compressing the content, and avoiding further perceptual degradation of the host content. In addition, methods, devices and computer program products are disclosed that obstruct differential analysis of such forensically marked content.

  • Patent number: 8344547
    Abstract: A system and method for operating a photovoltaic element at or near a maximum power point. A maximum power point tracker changes a voltage or current set point of a photovoltaic element in sequential discrete steps, measuring an output power at each step after a predetermined settling time. A slope of a power-voltage curve is then estimated and the slope is corrected for irradiance changes. Finally, an operating voltage or current of the photovoltaic element is adjusted based on the slope of the power-voltage curve and other factors, causing the photovoltaic element to operate at or near its maximum power.

  • Patent number: 8345238
    Abstract: A device for measuring spectrum of light includes a differential group delay (DGD) device positioned to receive light under measurement and to produce output light with a DGD value representing a difference in the group delay between two orthogonal optical polarizations of the light under measurement. An optical detector is positioned to receive the output light from the DGD device to measure a state and a degree of polarization of the output light. A processing device receives and processes measurements of the state and the degree of polarization from the optical detector. A probe light source produces probe light. An optical sensor receives the probe light and interacts with the probe light at a resonance wavelength of the optical sensor. A processing unit processes the optical spectrum of the returned probe light to extract information on a parameter to change the resonance wavelength.
