  • Patent number: 11939688
    Abstract: Photoelectrochemical (PEC) technology for the conversion of solar energy into chemicals may require cost-effective photoelectrodes to efficiently and stably drive anodic and/or cathodic half-reactions to complete the overall reactions for storing solar energy in chemical bonds. Apparatus and systems incorporating effectively transparent metal catalysts enable the design and/or implementation of PEC devices for light harvesting. Triple-junction photocathodes with the triangular catalyst grids are provided to improve the efficiency of the photocathodes to generate renewable fuel from sunlight.

  • Patent number: 10353803
    Abstract: A cluster of devices can be identified where results from executing a test by any cluster devices can be considered as being from the same device. Thus, instead of waiting for a single device to produce comparable results, multiple devices from the same cluster can simultaneously perform the test and obtain the needed set of test results more quickly. The technology can identify clusters of devices that are all similar to a primary cluster device. A device pair can be considered similar when (1) a mean each of a set of test results from each device are within a first threshold of each other, (2) a measurement of the consistency of each test result set are within a second threshold of each other, and (3) a measurement of the consistency of a combination of the test results sets is between the consistency measurements of the individual test result sets.

  • Patent number: 9755688
    Abstract: A MemEx Cell Phone Case for providing a combination of accessory functions in conjunction with a protective mobile device case, including a storable touchscreen stylus, a foldable, magnetically retained kickstand, an external memory expansion adapter, and openings for charging ports. The memory adapter permits consumers to increase the memory of their smart phone or other device which may be otherwise incapable or receiving a memory upgrade. The adapter includes a receptacle for commercially available memory storage devices such as a micro-SD card, and features a dust cover. The entire assembly is secured by a detachable phone retainer to ensure a positive connection between the phone and case functions. The MemEx case is designed to accommodate all the controls and functions of various mobile devices in a durable, utilitarian case while providing these additional accessories.

  • Patent number: 9727318
    Abstract: An apparatus to identify and purge unused code may comprise a processor circuit on a device and a storage component configured to store a codebase including one or more portions of programming code. The apparatus may further comprise a sampling component, a profiling component, and a purge component. The sampling component may sample the codebase and generate one or more leads identifying portions of programming code from the codebase determined to be unused during a sampling period. The profiling component may receive the one or more leads and profile programming code identified therein during a profiling period and to identify portions of programming code determined to be unused during the profiling period. The purge component may receive identification of the portions of programming code determined to be unused during the profiling period and initiate a purging process thereon. Other embodiments are described and claimed.

  • Publication number: 20150234652
    Abstract: Techniques to identify and purge unused code are described. In one embodiment, for example, an apparatus may comprise a processor circuit on a device and a storage component configured to store a codebase including one or more portions of programming code. The apparatus may further comprise a sampling component, a profiling component, and a purge component. The sampling component may be operative on the processor circuit to sample the codebase and generate one or more leads identifying portions of programming code from the codebase determined to be unused during a sampling period. The profiling component may be operative on the processor circuit to receive the one or more leads and profile programming code identified therein during a profiling period. The profiling component may be further operative on the processor circuit to identify portions of programming code determined to be unused during the profiling period.

  • Patent number: 8887142
    Abstract: Loop control flow diversion supports thread synchronization, garbage collection, and other situations involving suspension of long-running loops. Divertible loops have a loop body, a loop top, an indirection cell containing a loop top address, and a loop jump instruction sequence which references the indirection cell. In normal execution, control flows through the indirection cell to the loop top. After the indirection cell is altered, however, execution flow is diverted to a point away from the loop top. Operations such as garbage collection are performed while the loop (and hence the thread(s) using the loop) is thus diverted. The kernel or another thread then restores the loop top address into the indirection cell, and execution flow again continues through the restored indirection cell to the loop top.

  • Patent number: 8266604
    Abstract: Transactional memory compatibility type attributes are associated with intermediate language code to specify, for example, that intermediate language code must be run within a transaction, or must not be run within a transaction, or may be run within a transaction. Attributes are automatically produced while generating intermediate language code from annotated source code. Default rules also generate attributes. Tools use attributes to statically or dynamically check for incompatibility between intermediate language code and a transactional memory implementation.

  • Patent number: 6073774
    Abstract: A mixture of air, paper stock made from recycled paper, foaming agents and surfactants are injected into a pressurized container. The container has a stock inlet at an end opposite a stock outlet, and three outlets arranged along the top of the container between the stock inlet and the stock outlet. The first top outlet nearest the stock inlet is separated from the second and third outlets by a baffle, and the second and third outlets are separated from the stock outlet by a baffle. Each outlet has a valve which controls flow from that outlet. By adjusting the outlet valves, foam and waste ink is vented from the first and second outlets from the stock inlet, while stock is vented from the third outlet which is closest to the stock outlet. The stock passing through the third outlet is recycled through the container.

  • Patent number: 5271844
    Abstract: In a process for biodegrading under highly alkaline conditions organics in a waste stream derived from a Bayer processing system for producing aluminum oxides,i) the waste stream being typical of oxalate waste streams resulting from alkaline treatment of bauxite, the oxalate waste streams being rich in oxalates, formates, acetates, benzoates and sodium ions and having a pH in excess of 8,ii) treating the highly alkaline waste stream to neutralize and thereby lower pH and to reduce sodium ion concentration prior to introducing the waste stream into a bioreactor,iii) biodegrading the oxalates in the bioreactor by use of Pseudomonas genus microorganisms, andiv) discharging at least a portion of the biodegraded waste stream, the improvement being characterized by:a) introducing the highly alkaline waste stream rich in sodium ions to the bioreactor to avoid the treatment of step ii),b) biodegrading the organics in the waste stream with the Pseudomonas genus microorganisms characterized by ATCC 53883 deposited micr
