  • Publication number: 20250197461
    Abstract: In the present disclosure, a yeast interactive plasmid of a detoxifying enzyme glucosinolate sulfatase (GSS1) is constructed based on a yeast two-hybrid system and then screened with an Arabidopsis thaliana-yeast library, and a plant protein zeaxanthin epoxidase aba1 that interacts with the GSS1 is obtained for the first time. A zeaxanthin epoxidase gene, also known as an aba-1 gene, is an abscisic acid (ABA) synthase that can catalyze oxidative conversion of the zeaxanthin into all-trans violaxanthin, thereby generating carotenoid precursors required in an ABA biosynthetic pathway. Furthermore, a core peptide segment that interacts with the aba1 is obtained by continuously reducing the length of a GSS1 sequence and conducting one-to-one yeast two-hybrid verification with the aba1 sequence.

  • Patent number: 9977133
    Abstract: Examples are provided that enable a cellular network location assist to confirm a position determined using a sensor of a mobile device. As a result of global positioning system signals becoming unavailable due to the mobile device traveling indoors, the mobile device implements a sensor-based position determination that provides a position of the mobile device as the mobile device travels about a location. In order to confirm the reliability of the sensor-based position determination, the mobile device, after passage of time or after traveling some estimated distance, requests location assistance indications from the cellular network. A processor of the mobile device receives the location assistance indications and generates a directional vector based on several of the location assistance indications. Using the directional vector, the processor confirms the reliability of the dead reckoning position.

  • Patent number: 9781487
    Abstract: A device may receive information that identifies available content associated with multicast streams available for transmission via a network. The device may determine content selected from the available content. The selected content may be associated with a multicast stream available for transmission via the network. The device may receive the multicast stream associated with the selected content via an air interface. The device may process the multicast stream into a format compatible with a connection interface.

  • Publication number: 20150179037
    Abstract: Liquid ingress event detection methods and detectors are provided. Temperature and moisture data are synchronously collected from at least one sensor unit coupled to an electronic device susceptible to liquid damage. A rate of change of each of the temperature data and the moisture data are determined, to form respective temperature change rate data and moisture change rate data. Each of the temperature change rate data and the moisture change rate data are compared to at least one predetermined liquid ingress condition. A liquid ingress event is identified when at least one of the temperature change rate data or the moisture change rate data matches the predetermined liquid ingress condition. An indication of the identified liquid ingress event is stored.

  • Patent number: 8943204
    Abstract: Information is provided to a mobile device while reducing the number of traffic channels established over a predetermined time period. A pull client on a mobile device receives requests for information from applications on the mobile device. The pull client creates a timing list which includes the timing requirements for each application. Applications that have overlapping timing requirements are grouped together into the same timing group. Once the time for creating a traffic channel for one of the groups arrives, a traffic channel is created between the mobile device and a carrier gateway. Information for each respective application within the same timing group is obtained through the network using the same traffic channel. When the requested information is provided to all applications within the same timing group, the traffic channel is released after a predetermined time. The method is repeated for a next timing group entry.
