Abstract: An approach to detection and repair of application level semantic errors in deployed software includes inferring aspects of correct operation of a program. For instance, a suite of examples of operations that are known or assumed to be correct are used to infer correct operation. Further operation of the program can be compared to results found during correct operation and the logic of the program can be augmented to ensure that aspects of further examples of operation of the program are sufficiently similar to the examples in the correct suite. In some examples, the similarity is based on identifying invariants that are satisfied at certain points in the program execution, and augmenting (e.g., “patching”) the logic includes adding tests to confirm that the invariants are satisfied in the new examples. In some examples, the logic invokes an automatic or semi-automatic error handling procedure if the test is not satisfied.

Abstract: Authenticating a third party client system prior to providing Internet access via an Internet access point. In a distributed computing system including an Internet access point, an authentication service, and a third party client system, an authentication service receives an authorization request from a third party client system. The authorization request is initiated in response to a single action being performed by a user of the third party client system. The user is not required to manually submit any identification information. The authorization request includes a unique client identifier for identifying the third party client system. The method also includes verifying that the third party client system associated with the unique client identifier is authorized to access the Internet via the Internet access point. If the third party client system is authorized to access the Internet, Internet access is provided to the third party client system.

Abstract: Multi-directional currents are generated in a medium by cyclically reversing the direction of a conventional current applied to at least one of at least two electrodes so that an electromotive force (EMF) pulse travels from side of the electrode to the other, changing the direction of current in the medium. The multi-directional currents may be used to accelerate electrolytic processes such as generation of hydrogen by water electrolysis, to sterilize water for drinking, to supply charging current to a battery or capacitor, including a capacitive thrust module, in a way that extends the life and/or improves the performance of the battery or capacitor, to increase the range of an electromagnetic projectile launcher, and to increase the light output of a cold cathode light tube, to name just a few of the potential applications for the multi-directional currents.

Abstract: A flow-through muffler includes a plurality of heat conducting walls, baffles, or partitions that together define a plurality of passages arranged to form acoustic waveguides, attenuators, and/or cancellation chambers, the walls, baffles, or partitions increasing a surface area exposed to the exhaust gases to facilitate extraction of heat while attenuating or canceling the resulting sound pressure waves. The muffler may have a cooling arrangement mounted thereon, and thermoelectric generator elements or other heat-powered device, such as a reformer, connected across the heat differential between the cooling arrangement and an exterior surface of the muffler housing that is in thermal contact with the heat conducting walls, bafflers, or partitions. In addition, the muffler may be made tuneable by providing a device for varying a length of one of the passages relative to another passage, and by including a sound cancellation chamber at an intersection of the passages.

Abstract: A sound-cancelling flow-through muffler includes a linear first inner passage, and a curved or zig-zagged second outer passage that wraps around or surrounds the inner passage and that is situated between the linear first inner passage and an exterior wall of the muffler. The outer passage has a length that is equal to, or a multiple of, one-half the wavelength of sound to be cancelled by the muffler such that sound exiting the inner and outer passages destructively interferes or cancels in a sound cancellation or conversion chamber. In addition, the walls of the outer passage serve as a heat sink to extract heat from the exhaust stream and conduct the heat to the outside of the housing. Alternatively, the outer passage may have a closed such that reflects sound back toward the inner passage for cancellation, the walls of the outer passage continuing to serve as a heat sink to extract heat from the exhaust stream and conduct the heat to the outside of the housing.

Abstract: Emissions from systems that use a catalytic converter are substantially reduced by introducing hydrogen, or a hydrogen containing fluid or fuel component, into the exhaust stream being scrubbed by the catalytic converter, resulting in instant lightoff and a significant reduction in emissions. Hydrogen for injection into the exhaust stream may, optionally, be generated within the vehicle using heat recovered from the catalytic converter, and/or the engine or elsewhere in the exhaust system, by a thermoelectric generator, the electrical output of which may be used to perform electrolysis and/or to power a reformer in order to generate the hydrogen. The thermoelectric generator may be retrofit onto the catalytic converter, or integrated in a way that enhances thermoelectric generation, including providing a catalyst coated heat sink and integrated cooling pipes to enhance the thermal differential required for thermoelectric generation.

Abstract: Novel structures and methods for evaluating lines in semiconductor integrated circuits. A first plurality of lines are formed on a wafer each of which includes multiple line sections. All the line sections are of the same length. The electrical resistances of the line sections are measured. Then, a first line geometry adjustment is determined based on the electrical resistances of all the sections. The first line geometry adjustment represents an effective reduction of cross-section size of the lines due to grain boundary electrical resistance. A second plurality of lines of same length and thickness can be formed on the same wafer. Then, second and third line geometry adjustments are determined based on the electrical resistances of these lines measured at different temperatures. The second and third line geometry adjustments represent an effective reduction of cross-section size of the lines due to grain boundary electrical resistance and line surface roughness.
