  • Patent number: 10651036
    Abstract: Small size chip handling and electronic component integration are accomplished using handle fixturing to transfer die or other electronic components from a full area array to a targeted array. Area array dicing of a thinned device wafer on a handle wafer/panel may be followed by selective or non-selective de-bonding of targeted die or electronic components from the handle wafer and optional attachment to a carrier such as a transfer head or tape. Alignment fiducials may facilitate precision alignment of the transfer head or tape to the device wafer and subsequently to the targeted array. Alternatively, the dies or other electronic elements are transferred selectively from either a carrier or the device wafer to the targeted array.

  • Publication number: 20200112633
    Abstract: A method for using an intercom to implement an intelligent calling process, an intelligent calling apparatus and a system is presented. The method is adapted to a site that adopts intercoms to perform a calling process. The system utilizes a server for receiving a calling signal generated by an intelligent calling apparatus. The calling signal records ID information used to represent a calling location. The server obtains the calling location by querying a database. The software process running in the server combines voice signals according to the calling location. A calling voice is generated and sent to the intercoms carried by the personnel member. When any personnel members receive the calling voice by the intercom, this calling process can be completed as the personnel member arrives at the calling location.

  • Publication number: 20200068370
    Abstract: The disclosure is related to a method for intelligent calling service, an apparatus and a system thereof. The method is performed in a server. When the server receives a service request signal recording a device ID generated by an apparatus for intelligent calling service, call information of service personnel can be obtained based on a service location corresponding to the device ID by querying a database of the server. After that, the server issues a service call signal to service communication devices carried by the service personnel. When a distance between the service communication device and the apparatus for intelligent calling service reaches a threshold, it shows that one of the service personnel is in service. This calling service procedure is done when the server receives a dismissing signal generated by the apparatus or the service communication device near the apparatus.

  • Publication number: 20200068369
    Abstract: The disclosure is related to an IoT service system with a Bluetooth Low Energy mesh network, and a communication method thereof. The IoT service system includes multiple intelligent service calling devices, multiple service communication devices and an agent node forming a BLE mesh network. One service calling device generates a service request signal that is broadcasted over a BLE mesh network. When a server receives the service request signal through the agent node, a service personnel and his portable service communication device are obtained by querying a database according to identification information relating to the service calling device that generates the service request signal. A service calling signal is therefore formed and broadcasted over the BLE mesh network. If a distance between the service communication device and the service calling device reaches a threshold while the service personnel is in service, a service dismissing signal is generated.
