  • Publication number: 20240124298
    Abstract: Microelectromechanical devices and methods of manufacture are presented. Embodiments include bonding a mask substrate to a first microelectromechanical system (MEMS) device. After the bonding has been performed, the mask substrate is patterned. A first conductive pillar is formed within the mask substrate, and a second conductive pillar is formed within the mask substrate, the second conductive pillar having a different height from the first conductive pillar. The mask substrate is then removed.

  • Patent number: 11829314
    Abstract: A charging system includes a source terminal and a sink terminal. The control method of the charging system includes transmitting a bus voltage by the source terminal, determining whether the sink terminal has entered a sink attached state when the sink terminal receives the bus voltage, enabling a message transceiver of the sink terminal if the sink terminal has entered the sink attached state, transmitting a source message to the transceiver of the sink terminal by the source terminal, transmitting a request message to the source terminal by the message transceiver of the sink terminal while the source terminal transmits the source message, and continuing to enable a communication function for communicating with the sink terminal and continuing to transmit the bus voltage to the sink terminal by the source terminal when the source terminal receives the request message.

  • Publication number: 20230153575
    Abstract: The present disclosure provides an electronic device including a processor and a memory device. The memory device is configured to store a residual neural network group for restoring data and a multi-head neural network. The multi-head neural network contains multiple of self-attention neural modules. The processor is configured to perform the following steps. Multiple pieces of data corresponding to multiple of leads are input into residual neural network groups, respectively, to generate multiple of feature map groups respectively correspond to the leads. The feature map groups are classified to the self-attention neural modules according to labels of the feature map groups.
