  • Patent number: 9427592
    Abstract: Techniques are provided for use with implantable medical devices or trial medical devices for wirelessly connecting the devices to external instruments such as tablet computers or smartphones. In an example where the medical device is an implantable neurostimulator, the neurostimulator passively detects wireless wake-up signals generated by the external instrument, i.e. the neurostimulator “sniffs” for advertisement signals generated by the external instrument. In response to passive detection of a wake-up signal, the implantable neurostimulator determines if a response is warranted and, if so, the neurostimulator activates its wireless transmission components to transmit an acknowledgement signal to the external instrument so as to complete a wake-up and handshake protocol.

  • Patent number: 9419469
    Abstract: A control method for a wireless charging system has steps of performing impedance matching on an antenna of the wireless charging system; tracing an optimal frequency point by sending a sensing signal with a default transmission frequency, and calculating a transmission efficiency of the sensing signal; determining whether the transmission efficiency meets a transmission requirement. When the transmission efficiency does not meet the transmission requirement, repeats the previous steps with another default transmission frequency until the transmission efficiency meeting the transmission requirement. When the transmission efficiency meeting the transmission requirement, the default transmission frequency is defined as the optimal frequency point for charging.

  • Patent number: 9343415
    Abstract: In a method for forming a packaging structure, a metal pad is formed on a semiconductor substrate, and a first polymer insulating layer is formed over the semiconductor substrate. An opening passing through the first polymer insulating layer is formed to expose a portion of the metal pad. A copper-containing material is deposited in the opening and over the first polymer insulating layer, thereby forming a copper-containing layer having a first thickness and a first width over the first polymer insulating layer. A conductive bump having a second width is formed over the copper-containing layer, in which the second width is smaller than the first width. An exposed portion of the copper-containing layer is etched using the conductive bump as a mask until the exposed portion is reduced to a second thickness, thereby forming a monolithic copper-containing structure.
