Publication number: 20160255196Abstract: An ALI/ESME steering gateway bridges the nationwide ALI/ESME network notes (or PSAPs) with the GMLC/MPCs of various different XPC networks. The steering gateway provides a unified interface between the PSAP/ALI network and positioning centers (GMLC/MPC/VPCs). Using the steering gateway, an E911 service provider accesses positioning centers (GMLC/MPC/VPC) of any XPC network. This access by the ALI to the positioning center is accomplished with any type of interface, irregardless of the protocol type. The connectivity of each virtual communication path between ALIs and PSAPs is managed. The ALI/ESME steering gateway also provides translation of the protocols between the two ALI-MPC interface sets (inbound and outbound). The ALI/ESME steering gateway also consolidates (or “de-duplicates”) any/all duplicated requests from a same ALI or PSAP for the same emergency call so that only one request is then sent to the destined positioning center within the relevant network.Type: ApplicationFiled: February 2, 2016Publication date: September 1, 2016Inventors: Yinjun Zhu, Cristine Connor, Gordon John Hines, Hsin-Chih Liao, William Pelligrini

Publication number: 20160165487Abstract: A technique to allow a server such as a location server to throttle concurrent or closely timed location requests for the position of a given wireless device such that within a certain time period preferably only one location request will be initiated to the positioning engine and the remaining closely-timed location requests will be buffered or cached. When a position for the given wireless device is returned per the outstanding location request, then the retrieved position will be used to respond to each of the buffered location requests. Thus, a plurality of location requests are satisfied with a single request to the positioning engine. By optimizing the use of cached position requests, throttling of location requests per the invention reduces network traffic significantly, increases the efficiency of a positioning server (therefore reducing business cost), and provides for an improved grade or quality of location based services in general.Type: ApplicationFiled: February 4, 2016Publication date: June 9, 2016Inventors: YINJUN ZHU, GORDON JOHN HINES, VICTOR BURTON, HSIN-CHIH LIAO

Publication number: 20130290346Abstract: A geographic information system (GIS) includes a created link between GIS objects in the database of the geographic information system (GIS), and performed GIS operations. The linked GIS object and performed GIS operation provides a mechanism to more easily identify the impact of making an update to a GIS database. A database association is maintained between GIS object identifiers and the requesting GIS operation to enable a reverse trace back from the nature of the GIS operation to the GIS object involved.Type: ApplicationFiled: April 29, 2013Publication date: October 31, 2013Inventor: Hsin-Chih Liao

Patent number: 6524970Abstract: This invention disclose a method for growing a barium titanate layer by means of liquid phase deposition (LPD), which characterizes by low cost, low-temperature growth, and easily practice. This novel method for growing a barium titanate characterizes by mixing a barium nitrate solution and hexafluorotitanic acid solution to produce a barium titanate solution. Next, a boric acid solution is added to the barium titanate solution to prepare a barium titanate growth solution. Then a substrate, such as a wafer, ready to grow a barium titanate layer thereon is dipped in this growth solution for a period of time at a suitable temperature. Thereafter, a barium titanate dielectric layer with the properties of high dielectric constant, low leakage current and breakdown resistant can be formed on the substrate.Type: GrantFiled: October 26, 1999Date of Patent: February 25, 2003Assignee: Winbond Electronics Corp.Inventors: Ming-Kwei Lee, Hsin-Chih Liao

Publication number: 20020155859Abstract: The present invention pertains to a voice broadcasting method on cellular phone's buttons. The method is applied to let users listen and learn the corresponding message of each button on the cellular phone through the way of voice broadcasting in the meantime while they operate the keypad on the cellular phone. When users dial numbers or set any function of the cellular phone, according to the steps' order of the buttons being operated the present invention informs users the steps' names by voice broadcasting at the right moment so that users are able to assure themselves whether the steps are correct or not. Due to the present invention capable of providing synchronous voice broadcasting of cellular phone's buttons, especially, when the light is dim in the operating surroundings or the cellular phones do not have any spontaneous light source, users are still able to confirm the accuracy of dialing numbers or setting functions.Type: ApplicationFiled: April 18, 2001Publication date: October 24, 2002Inventors: Kun- Huei Chen, Hsin-Chih Liao
