  • Patent number: 10203443
    Abstract: A light emitting device includes a light guide plate and a light source. The light guide plate has a first surface, a second surface that is opposite to the first surface, at least one third surface, and a light incident surface. The third surface and the light incident surface are between the first and second surfaces. The third surface is adjacent to the light incident surface and has a concave-convex structure. The light source is located on the light incident surface. When the light source emits light, the light of the light source enters the light guide plate and transmits to the concave-convex structure, such that the light irradiates out from the concave-convex structure due to refraction, and is reflected back to the light guide plate by the concave-convex structure.

  • Publication number: 20180335473
    Abstract: A top housing having a back slot and a front slot parallel with each other, and both stacked on top of a row of lower slots, which is perpendicular to the back and front slots. In this way, the juxtaposition of the back and front slots and the row of lower slots forms two rows of virtual rectangular through-openings. The back of these rows receives a row of first contacts extended through them. The front of these rows receives a row of second contacts extended through them. The through-openings thus guide the contacts at a position of the contacts that is very close to where they contact the lead of the DUT. Hence, there is a very high amount of precision and control of the contact tip that contacts the lead of the DUT.

  • Patent number: 10080169
    Abstract: Systems, apparatus and methods for facilitating identification and/or acquisition of an access point are provided. Methods can include transmitting or receiving access point information (“API”) indicative of an identification of the access point (“AP”). The API can be provided at the AP through hardwiring or receipt of configuration information input by a user or transmitted to the AP by a network operator through Over-The-Air (“OTA”) signaling. The API can be computer-readable and, in some embodiments, the API can also be human-readable. The API can be transmitted on a paging channel from which user equipment (“UE”) can receive information. The frequency at which the API is transmitted can be fixed, dynamic and/or configurable. Upon receipt of the API, acquisition of the AP is attempted if the AP is determined to be a permitted AP.

  • Patent number: 10045322
    Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.

    Abstract: An electronic device and a method for detecting a malicious file are provided. The method includes the following steps: An executable file is searched, and an import table is extracted from the executable file. The import table includes at least a name of a first DDL and a name of a second DDL. A distance between the first DLL and the second DLL is calculated. Whether the distance exceeds a threshold is determined. If the distance exceeds the threshold, then whether a duplicate content of the import table exists in the executable file is checked. The executable file is regarded as a malicious file if the duplicate content of the import table exists in the executable file.

  • Publication number: 20180121545
    Abstract: The disclosed methods, systems, and apparatus use Natural Language Processing (NLP) in conjunction with a world model and cognitive frames to semantically analyze, understand, rank, store, and retrieve digital text. The goal is to improve the relevance, usefulness and efficiency of information search. The world model represents things existing in the real world whereas cognitive frames specify possible user interaction with such a world. Using NLP in conjunction with a world model and cognitive frames to understand text is an advancement in automated text analysis. It addresses three serious shortcomings of the existing search technology: the inadequate measure of the meaningful content in web pages; a poor understanding of users' goals and tasks in their search and, the irrelevant search results. The disclosed methods have led to the successful implementation of a full-scale semantic search engine in medicine, and they are applicable and adaptable to other disciplines.
