  • Publication number: 20240113032
    Abstract: Interconnect structure packages (e.g., through silicon vias (TSV) packages, through interlayer via (TIV) packages) may be pre-manufactured as opposed to forming TIVs directly on a carrier substrate during a manufacturing process for a semiconductor die package at backend packaging facility. The interconnect structure packages may be placed onto a carrier substrate during manufacturing of a semiconductor device package, and a semiconductor die package may be placed on the carrier substrate adjacent to the interconnect structure packages. A molding compound layer may be formed around and in between the interconnect structure packages and the semiconductor die package.

  • Patent number: 10490052
    Abstract: A motion-sensing floor mat, an assembly of such floor mats, and a monitoring system with such floor mats are provided; wherein the floor mat can be joined with another such floor mat and electrically connected to a monitoring device to form the monitoring system; the monitoring device stores a queue list and a topology matrix and uses a topological algorithm to store the identification tag of each such floor mat detected into the queue list in order, to gradually establish the topology matrix for the floor mats detected; and to thereby obtain the relative positions of the floor mats detected. When any of the floor mats is subjected to pressure (e.g., when someone falls on the floor mat accidentally) and generates a sensing signal, the monitoring device can pinpoint the position of that floor mat (i.e., the location of the fall) rapidly according to the topology matrix.

  • Publication number: 20180101599
    Abstract: An “Interactive Text Completion System” provides various techniques for presenting a user with personalized context-based multi-word text completion suggestions via a user interface. The multi-word text completion suggestions are updated in real-time as the user types and/or selects one or more words of the completion suggestions. The Interactive Text Completion System applies a language model in combination with a document context to generate the completion suggestions. In various implementations, the language model is generated from a store of prior documents created or edited by the user. As such, the language model is personalized to individual users based on prior documents of those users. However, any desired source or corpus of existing documents can be used to generate the language model. The resulting language model offers relatively long completion suggestions (e.g., phrases consisting of a sequence of multiple words) based on the current document context.

  • Publication number: 20150364023
    Abstract: The present invention is to provide a monitoring system including a plurality of motion sensing carpets and a monitoring device (e.g., a computer) electrically connected to one of the motion sensing carpets serving as a control unit while all the other motion sensing carpets directly or indirectly joined to the control unit serves as auxiliary units. The monitoring device is able to carry out a topology algorithm and then establish a topology matrix of the motion sensing carpets in a stepwise manner so as to obtain the relative location of each motion sensing carpet. When any of the motion sensing carpets is subjected to pressure caused by a senior member or child in the family toppling over thereon (e.g., an accident) and generates a sensing signal, the monitoring device can rapidly know from the topology matrix the exact location of the accident according to the sensing signal.
