  • Publication number: 20240153842
    Abstract: A semiconductor structure includes a die embedded in a molding material, the die having die connectors on a first side; a first redistribution structure at the first side of the die, the first redistribution structure being electrically coupled to the die through the die connectors; a second redistribution structure at a second side of the die opposing the first side; and a thermally conductive material in the second redistribution structure, the die being interposed between the thermally conductive material and the first redistribution structure, the thermally conductive material extending through the second redistribution structure, and the thermally conductive material being electrically isolated.

  • Publication number: 20240113071
    Abstract: An integrated circuit package including electrically floating metal lines and a method of forming are provided. The integrated circuit package may include integrated circuit dies, an encapsulant around the integrated circuit dies, a redistribution structure on the encapsulant, a first electrically floating metal line disposed on the redistribution structure, a first electrical component connected to the redistribution structure, and an underfill between the first electrical component and the redistribution structure. A first opening in the underfill may expose a top surface of the first electrically floating metal line.

  • Patent number: 11927303
    Abstract: A wearable device includes a host, a first belt, a second belt, a circuit board, a cable, and an adjustment mechanism. The first belt, one end of which is connected to a first side of the host, has a cable holding part. One end of the second belt is connected to a second side of the host. The circuit board is disposed at an overlap of the first belt and the second belt. A first end and a second end opposite to each other of the cable are connected to the circuit board and the first side respectively, and a holding section of the cable is fixed to the cable holding part. The adjusting mechanism is disposed at an overlap of the first belt and the second belt to adjust an overlapping length of the first belt and the second belt.

  • Patent number: 9172662
    Abstract: A virtual chassis system includes a plurality of network nodes configured with a master virtual chassis address. The network nodes are connected by virtual fabric link (VFLs) that provide a connection for exchange of data packets between the network nodes. The data packets include source MAC addresses and associated hardware device information, such as source chassis ID, source network interface identifier and source port identifier information. The network nodes use this information to maintain synchronized MAC address tables for forwarding of data packets in the virtual chassis system. One or more control protocols in the network node are used for topology discovery, master network node election, generation of routing tables, health monitoring and other functions.

  • Patent number: 9148390
    Abstract: A virtual chassis system includes a plurality of network nodes configured with a master virtual chassis address. The network nodes are connected by virtual fabric link (VFLs) that provide a connection for exchange of packets between the network nodes. The virtual chassis system is operable to provide warnings to help prevent a virtual chassis split event in response to an administrative action. The topology of the virtual chassis system is analyzed to determine the possible impact of one or more administrative actions. Based on this analysis, a warning is generated when an administrative action is requested that may lead directly or indirectly to a virtual chassis split.
