Abstract:
An electronic apparatus includes a PCB with a heat generating electronic component disposed thereon, a heat sink, and a mounting device for mounting the heat sink onto the heat generating electronic component. The mounting device includes a mounting frame and a wire clip. The mounting frame surrounds the heat sink, and includes two first mounting arms and two second mounting arms disposed above the first mounting arms. The first mounting arms abut on the PCB. A pair of engaging wings are formed on the second mounting arms. The wire clip includes a pivot axle pivotably attached to the mounting frame and two resilient arms at opposite sides of the mounting frame. The resilient arms abut against the heat sink and engage with the engaging wings, thereby exerting a resilient force on the heat sink toward the heat generating electronic component.

Also described are a method and apparatus for content delivery including receiving content from a first network, performing a handover, receiving content from a second network, determining if any content is missing and requesting the missing content.
Abstract:
A method and apparatus are described for gaining access to a communication medium in a contention-based network, including determining a slot count based on a number of stations in the contention-based network, adjusting the slot count, initiating a frame transmission when the slot count reaches a predetermined value and wherein said number of stations and an address queue are adjusted to reflect a priority. Further, a method and apparatus are described for gaining access to a communication medium in a contention-based network, including receiving a slot count based on a number of stations in the contention-based network, adjusting the slot count, initiating a frame transmission when the slot count reaches a predetermined value and wherein said number of stations and an address queue are adjusted to reflect a priority.
Abstract:
A multicast/unicast admission control method, a multicast/unicast admission control device, and a multicast/unicast admission control system are provided. In the method, through centralized resource control of a resource and admission control subsystem (RACS), sharing of multicast/unicast resources is realized. The RACS allocates and authorizes resources to an access node (AN), the AN manages the obtained multicast resources under the authorization, and the resource allocation is adjusted through interaction when the multicast resources of the AN or the resources of the RACS are not sufficient.
Abstract:
The embodiment of this invention discloses a method, a system and an apparatus for admission control of multicast or unicast. The method for admission control of multicast comprises: a network device receives a multicast request and executes admission control operation of multicast resources according to the multicast request; when multicast resources are not sufficient, the network device sends an outer resources request to a resources admission control device, and executes multicast operation according to the results of admission control operation returned by the resources admission control device responsive to said outer resources request. The method for admission control of unicast comprises: a resources admission control device receives a unicast resources request and executes admission control operation of unicast resources according to the unicast resources request; when the unicast resources are not sufficient, the resources admission control device sends an outer resources request to a network device; the resources admission control device executes unicast operation according to the results of admission control operation returned by the network device responsive to said outer resources request. The embodiment of this invention guarantees fast handoff of multicast service channel in the case of implementing resources share of multicast services and unicast services, and the implementation is simple.
Abstract:
A method for transmitting data in TDM mode is provided to solve the problem in the prior art that the data processing between a transmitter side and a receiver side could not be real time and the delay time during data transmitting would be longer. The method comprises: packaging TIME DIVISION MULTIPLEXING (TDM) frame head information and data to be sent into a TDM frame at a transmitter side, and transmitting the TDM frame to a receiver side; receiving the TDM frame at the receiver side. With the solution according to the present invention, it is possible to perform real time data processing between the transmitter side and the receiver side and shorten the delay time during data transmitting.
Abstract:
An adaptive and scalable packet error correction apparatus and method in a wireless multicast network is provided. Each retransmission request from a receiver contains a round number and the number of repairs sent in that round. At each receiver, there are two counters for counting the rounds sent out on the network and the number of repairs that have been required. A receiver on the wireless multicast network listens to the ARQ requests sent by other receivers to update the two counters and determines whether its request should be suppressed or be sent out.
