Abstract: Techniques relating to communicating system events in universal serial bus (USB) power delivery (PD) devices are described. In an example, a USB PD controller receives a notification of a system event in a first device associated with the USB PD controller, the system event being based on one of a change in machine state of the first device and occurrence of a user interaction event in the first device. A PD protocol based message, indicative of the system event in the first device, is generated. The PD protocol based message provides for activation of a predefined profile setting in a second device, wherein the second device is to interface with the first device through the USB PD controller.

Abstract: Films with optical transmittance of >80% between 400 and 750 nm and with coefficient of thermal expansion less than 20 ppm/° C. are prepared from aromatic polyamides that are soluble in polar organic solvents yet have glass transition temperatures>300° C. The films are cross-linked in the solid state by heating at elevated temperatures for short periods of time in the presence of multifunctional epoxides. Surprisingly, the optical and thermal properties of the films do not change significantly during the curing process. The temperature required for the crosslinking process to take place can be reduced by the presence of a few free, pendant carboxyl groups along the polyamide backbones. The films are useful as flexible substrates for electronic displays and photovoltaic devices.

Abstract: A fluorine-containing triazolopyridine represented by formula (I) and a racemate, R-stereoisomer, S-stereoisomer, pharmaceutically acceptable salt, or mixture thereof are described. The triazolopyridine can be used as a positive allosteric modulator of an mGluR2, and is highly selective in activating the mGluR2, exerting no activation or very limited activation of other homologous metabotropic glutamate receptor. The triazolopyridine can thus be used to prepare a product for treating an mGluR2-related disease, such as a central nervous system disease or neurological disease.

Next, the system identifies a subset of action labels within the sequence of action labels. The system next extracts a set of gait features for the person from a subset of video frames within the sequence of video frames corresponding to the subset of action labels. Subsequently, the system analyzes the set of extracted gait features to generate a fall risk assessment for the person.

Abstract: The present invention provides a method and apparatus for dewatering a biological solid material employing both microwave irradiation and solvent extraction. The method comprises microwave irradiation pretreatment, solvent extraction dewatering, solid-liquid separation, and solvent recovery. Through microwave irradiation of an aqueous biological solid material, gaps in the solid material are increased, and the biological material is fractured, thus releasing more bound water in the solid material. Subsequently, the microwave-irradiated biological solid material is brought into full contact with an organic solvent, allowing the solvent to absorb and extract moisture from the solid, thus removing moisture from the solid. The aqueous solvent is then subjected to evaporation under reduced pressure or gasification under reduced pressure in a separation apparatus so as to separate the moisture and the solvent. The solvent is then compressed, condensed and recovered for recycling.
