  • Patent number: 10768586
    Abstract: It is advantageous to switch an active element with a background element. By using a switching mechanism, a background element can be made active while the application remains active. That is, the application does not need to be taken offline to switch the active element with a previously loaded background element. Single input/single output (SISO) relationships are defined for background elements and an active element which provides one or many functions and an active element which provides one or many functions between one input variable and one output variable. The switching mechanism acts on a given SISO relationship to determine the background element to use to replace the active element.

    Abstract: Techniques are provided for power optimization of home automation system devices (e.g., battery-powered devices). In one example embodiment, the power optimization is based on service states for a room associated with the device. A service state is determined for each of one or more services available in the room. The device is maintained in a low-power inactive state while there are no active services in the room. In response to at least one service being activated, the device transitions from the inactive state to a full-power in-use state. Such transition is performed preemptively, absent any current attempt to use the device by a user or another device. In response to expiration of a timer since a last use of the device or the transition to the in-use state was made and no actual use occurred, the device exits the in-use state and may eventually return to the inactive state.

  • Patent number: 10067600
    Abstract: The disclosure provides a touch display panel. A scan line enters a display mode and a touch mode in a scan period. In the display mode, the scan line receives a first voltage to turn off a switch unit and enable a pixel unit to receive a pixel voltage signal from a first signal transmission line; and in the touch mode, the scan line receives a second voltage to turn on the switch unit and disable the corresponding pixel unit to stop receiving the pixel voltage signal, such that a sensing pixel unit outputs a touch sensing signal to the first signal transmission line through the switch unit, wherein the first voltage is greater than the second voltage. In the disclosure, an aperture ratio of the touch display panel is improved efficiently to meet the requirement of narrow border design of the touch display panel.

    Abstract: Self-referenced reading of a memory cell in a memory includes first applying a read voltage across the memory cell to produce a sample voltage. After applying the read voltage, a write current is applied to the memory cell to write a first state to the memory cell. After applying the write current, the read voltage is reapplied across the memory cell. An offset current is also applied while the read voltage is reapplied, and the resulting evaluation voltage from reapplying the read voltage with the offset current is compared with the sample voltage to determine the state of the memory cell.

  • Patent number: 9684319
    Abstract: A method for entering an operation mode in a low-temperature environment is applicable in a situation that plural electronic devices in an electronic apparatus are not activated. Through performing the method, the electronic apparatus obtains a temperature of each electronic device after receiving a request of a user. Then the electronic apparatus determines whether the temperatures of all the electronic devices reach a threshold value. If the temperatures of at least two electronic devices do not reach the threshold value, the electronic apparatus generates a plurality of corresponding enable signals for the electronic devices having the temperatures lower than the threshold value. The waveforms of the enable signals vary alternately. The electronic apparatus transfers the enable signals to a plurality of corresponding heaters. Being activated by the received enable signal, each of the heaters heats the corresponding electronic device.

  • Patent number: 9671764
    Abstract: The present invention is to provide a control system including a sensing device capable of periodically driving a corresponding operation device based on a trigger policy, wherein the sensing device and the operation device have the same trigger policy stored therein. The control system is characterized in that the trigger policy at least includes a trigger code, a time data (such as “after 15 minutes”) and an operation data (such as “turn on a lamp”). When the sensing device detects a sensing signal, the sensing device generates and transmits a trigger instruction to the operation device. When the operation device determines that a trigger code carried in the trigger instruction matches with a second identification code stored therein, the operation device calculates an expiration time of the time data based on the current time, and then executes an action corresponding to the operation data at the expiration time.
