  • Patent number: 9336878
    Abstract: A first memory cell including a phase change material. The first memory cell is programmable to store one data value of a plurality of data values. The plurality of data values are represented by a plurality of non-overlapping ranges of resistance of the first memory cell. At least one testing pulse is applied to the first memory cell to establish a cell resistance of the first memory cell in an intermediate range of resistance, the intermediate range of resistance in between first and second adjacent ranges in the plurality of non-overlapping ranges of resistance representing the plurality of data values. After applying the at least one testing pulse to the first memory cell, it is determined whether to apply at least one healing pulse to repair the first memory cell, depending on relative values of (i) the cell resistance in the intermediate range of resistance and (ii) a reference resistance in the intermediate range of resistance.

  • Patent number: 9312029
    Abstract: A memory device and associated controlling method are provided. The memory device includes a memory cell array, a sensing unit and a controller. The memory cell array has a plurality of memory cells. The sensing unit is electrically connected to the memory cell array and the controller. The sensing unit senses characteristic of a memory cell of the plurality of memory cells. The controller determines whether the characteristic of the one of the memory cells deviates and accordingly controls the memory cell array.

  • Patent number: 8942253
    Abstract: A system for data transmission on wireless alternating switching channels comprises a user, which allows a user to have at least an additional service on multiple service channels. The user sends at least a service forwarder a request to get at least an additional service, and receives the replied information of a specified forwarding channel. Before the connection between the user and the service forwarder fails or ends, the user receives original service and the service forwarder uses a specified service channel and transmits or receives additional service data for the user in the service channel interval; while in the control channel interval, the service forwarder uses the specified forwarding channel and transmits selective control message and selective additional data for the user, and the user switches to the specified forwarding channel to receive the selective control messages and the selective additional data.

  • Patent number: 8896432
    Abstract: A cooperative event data record system includes an in-car system working cooperatively with a communication system. The in-car system has a communication module, a cooperative event record processing unit and an impact determination module. The cooperative event record processing unit connects to the communication module, the impact determination module and an event data record unit. The impact determination module transmits a signal to the cooperative event record processing unit. The communication module transmits a request from the cooperative event record processing unit to a communication module element of the communication system, and receives a response from the communication module element. According to the response, the cooperative event record processing unit stores at least a video data to the event data record unit, or retrieves video data from the event data record unit.

  • Publication number: 20140286325
    Abstract: A vehicle network transmission method and a vehicle network transmission system are provided. The vehicle network transmission method comprises the following steps. A first transmission device transmits a data signal to a second transmission device. It is determined whether the second transmission device is located in a target area. If the second transmission device is located in the target area, then a geographic location of the first transmission device is retrieved and a transmission region of the first transmission device is calculated. It is determined whether all of the third transmission devices adjacent to the second transmission device in the target area are located in the transmission region. If all of the third transmission devices adjacent to the second transmission device in the target area are located in the transmission region, then the second transmission device does not continue forwarding the data signal.
