  • Publication number: 20180034263
    Abstract: A diagnostic system for a DC-DC voltage converter is provided. A first temperature sensor generates a first temperature signal associated with a buck mode integrated circuit. A first analog multiplexer outputs the first temperature signal to a first analog-to-digital converter which generates a first temperature value. A second temperature sensor generates a second temperature signal associated with a boost mode integrated circuit. A second analog multiplexer outputs the second temperature signal to a second analog-to-digital converter which generates a second temperature value. A microcontroller generates control signals to command first and second bi-directional switches in the DC-DC voltage converter to each transition to an open operational state if the first temperature value is greater than a first threshold temperature value.

  • Publication number: 20180030520
    Abstract: The present invention provides compositions, apparatuses and methods for detecting one or more nucleic acid targets present in a sample. Methods of the invention include utilizing two or more ligation probes that reversibly bind a target nucleic acid in close proximity to each other and possess complementary reactive ligation moieties. When such probes have bound to the target in the proper orientation, they are able to undergo a spontaneous chemical ligation reaction that yields a ligation product that is directly detected or that is amplified to produce amplicons that are then detected. The present invention also provides methods to stabilize sample RNA so that degradation does not significantly affect the results of the analysis.

The mobile device comprises a recording module, a fragmented media data (FMD) codec, a segmented media data (SMD) codec and a wireless communication module. The recording module records an event on the scene and generates a real-time video stream. The FMD codec encodes the real-time video stream into fragmented media data comprising a start fragment information, at least one media fragment and a media fragment (MF) random access point. The SMD codec directly segments the fragmented media data into a plurality of segmented media data, which are a start segment and at least one play segment. The SMD codec automatically and sequentially transmits the segmented media data to the server. Finally, the server pushes the segmented media data to the client terminal for play through a browser.

  • Publication number: 20180032650
    Abstract: Methods and systems are provided for generating a predictive tachometer profile at a tachometer of a vehicle. When an inertia phase of a transmission shift event is determined to be in progress, the predictive tachometer profile can be computed based on: a computed shift completion percentage; a difference between the current attained gear speed and the commanded gear speed; and a commanded engine torque that is determined based on the accelerator pedal position and the vehicle speed. The predictive tachometer profile can then be displayed at the tachometer. The predictive tachometer profile accounts for delays in a signal path between an engine speed sensor and the tachometer.
