  • Publication number: 20220043052
    Abstract: A semiconductor component burn-in test module includes a burn-in board and an external power transmission component. The burn-in board includes a plurality of burn-in seats, wherein a plurality of chips are disposed on the burn-in seats. The external power transmission component is arranged at opposite two sides of the burn-in board, where the external power transmission component includes a plurality of conductive members and a plurality of terminal seats. The burn-in board is provided with a plurality of wirings corresponding to the external power transmission component. As such, electric power can be conveyed to the plural burn-in seats of the burn-in board, through the plural terminal seats and the plural conductive strips. This decreases the length and the number of copper foil wirings in the burn-in boards for power transmission, so as to lower the cost of the burn-in boards.

  • Patent number: 10104643
    Abstract: A method of managing bandwidth resources provided by multiple network interfaces is proposed. When one or more network interfaces provide network bandwidth resources, a bandwidth manager manages all available bandwidth resources based on a list of decision criteria. The list of decision criteria includes energy efficiency, network throughput, channel condition, device mobility, and user preference. An application traffic flow distributor dynamically adjusts the amount of traffic flows on different network interfaces according to the joint decision based on the decision criteria. A network interface manager dynamically enables or disables each network interface according to the joint decision based on the decision criteria. Furthermore, a device movement analyzer analyzes and predicts device movement to facilitate accurate decision making of the bandwidth management.

  • Patent number: 10028109
    Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID.

  • Patent number: 9349540
    Abstract: The present invention provides a method for manufacturing platinum nanoparticle solution and a self-assembled platinum counter electrode thereof. The present invention adopts a polyol reduction method and controls the reduction reaction periods under various pH conditions. After the platinum nanoparticle dispersion solution of uniformly distributed platinum nanoparticles having small sizes is produced, the self-assembled platinum nanoparticles are adsorbed on a functionalized surface of a conductive substrate by dip coating at the normal temperature. Therefore, the structure of a platinum nanoparticle monolayer is formed, to obtain the self-assembled platinum counter electrode with a homogeneous single layer on the surface. This process is much simpler without adding any stabilizers or surfactants, without involving any subsequent heat treatments, and it consumes less amount of the platinum material.
