Abstract: An electronic compressor bypass valve (eCBV) module includes a pedestal housing, and a compressor bypass valve mounted to the pedestal housing. An inlet port, a first outlet port, and a second outlet port are integrally formed as part of the pedestal housing, where pressurized air flows into the inlet port. The eCBV module also includes a venturi device at least partially disposed in the second outlet port. When the compressor bypass valve is in an open position, a portion of the pressurized air flows through the first outlet port, and a portion of the pressurized air flows from the inlet port through the venturi device and through the second outlet port. When the compressor bypass valve is in the closed position the pressurized air is prevented from flowing into the first outlet port, and all of the pressurized air flows through the venturi device and through the second outlet port.

Abstract: An ultrasonic transducer that includes a delay line, a piezoelectric element, and a metal conductive layer between the delay line and the piezoelectric element. The delay line and the piezoelectric element are acoustically joined with an atomic diffusion bond to facilitate coupling ultrasonic waves from the piezoelectric element into the delay line or from the delay line into the piezoelectric element.

Abstract: An ultrasonic transducer that includes a delay line, an active piezoelectric element, and interposing metal conductive layer between the delay line and active piezoelectric element. The delay line and active piezoelectric element are joined so that ultrasonic waves may be coupled from the active piezoelectric element into the delay line or from the delay line into the active piezoelectric element. A via is formed, using a milling operation, in the active piezoelectric element to expose the edge of the interposing metal conductive layer between the delay line and active piezoelectric element. A conductive layer makes electrical contact between the interposing metal conductive layer and the surface of the active piezoelectric element to allow an electrical connection to be made from the surface of the active piezoelectric element to the interposing metal conductive layer.

Abstract: In general, the subject matter described in this specification can be embodied in methods, systems and program products. A server system receives from a plurality of computing devices indications that a user of each of the computing devices requested to receive posts that a first user authors. The server system receives from a first computing device a post that was authored by the first user. The post is transmitted from the server system to the plurality of computing devices. A score for the post is determined to satisfy a criteria for transmission to a second user who has not requested to receive posts authored by the first user. The determination uses a distance of the second user to the first user in a social network graph. In response, the post is transmitted from the server system to a second computing device that is associated with the second user.

Abstract: A method of managing a display of applications on a computing device can include identifying a plurality of contexts in which the computing device is used, each context being associated with (i) one or more signals and (ii) a plurality of applications. The method can also include detecting at least a subset of the signals during usage of the computing device and determining, based on the detected signals, that the computing devices is being used within a first context. The method can further include ranking, based on usage of the computing device, the applications associated with the first context. The method can still further include displaying, based on the ranking, representations of a first subset of the applications associated with the first context on a display of the computing device.

Abstract: Thrombostasin is an anti-clotting protein found in saliva of Haematobia irritans. Disclosed herein are studies testing blood uptake of horn flies feeding on cattle which confirm the association of ts genotype with blood uptake of horn flies. Blood uptake volumes of homozygous ts10 horn flies were lower than those of other ts genotypes when fed on control cattle. Cattle vaccinated with recombinant protein isoforms rTS9 or rTB8 resisted horn fly feeding by yielding lower blood volumes compared to flies feeding on control cattle. The impact of vaccination varied by ts genotype of flies. Cattle vaccinated with isoforms rTS9 resisted flies of ts2, ts9, and tb8 genotype. Vaccination with isoforms rTB8 produced resistance to ts8, ts9 and tb8 genotype flies. Horn flies of genotype ts10 were not affected with either TS isoforms and fed well on rTS9 and rTB9 vaccinated as on control-vaccinated cattle.

Abstract: A method and system for camera calibration comprises configuring a calibration target comprising calibration reflectors on a test vehicle. Video of a test scene is collected. Next the test vehicle is identified as it enters the test scene and recorded as it passes through the test scene. The position of the calibration target in each frame of the video is determined and the corresponding individual position of each calibration reflector for each frame of the recorded frames is used to construct a camera calibration map to calibrate the video camera.
