    摘要: In a wireless communication system, dynamic payload header suppression (DPHS) is applied to a data stream to reduce header overhead. DPHS allows the suppression of static fields as well as fields that change in a predictable manner (i.e., predictably dynamic fields). To suppress predictably dynamic fields, delta encoding is utilized to enable a cable modem to replace a dynamic field with information indicating how the field is different from the same field in a previous packet in the data stream. DPHS constructs a suppression mask by using a special packet called a “learn” packet. The “learn” packet is a copy of the original packet with extra bytes that guide the suppression process. It indicates that both the sending and receiving entities are to take a full copy of a packet header, which is then used as a reference to reconstruct the suppressed fields.

    摘要: A heat sink includes a heat sink body including a number of fins and a cavity for holding a phase change material and a number of particles to enhance the mixing of the phase change material during the operation of the heat sink. In operation, the body of the heat sink conducts thermal energy to the phase change material. The energy is absorbed during the phase change of the phase change material. After absorbing energy and changing to a liquid state, the phase change material continues to dissipate energy by convection. The convection currents in the cavity are directed by the shape of the cavity surfaces and enhanced by the particles intermixed with the phase change material.

    摘要: A system and method for adjusting the filtering of acknowledgments (ACKS) in a TCP environment. State variables are used to keep track of, first, the number of times an ACK has been promoted into (a variable which can be stored on a per-packet basis along with the session ID), and second, the number of times an ACK is allowed to be promoted into (which can be global, or can be stored per-session).

    摘要: Improved methods for performing burn-in of electronic components, such as integrated circuits (ICs) with on-board thermal sense circuits, are used to obtain a higher bin split. According to an embodiment, a thermal set-point is loaded into each IC. While the ICs are maintained at a constant elevated temperature, the burn-in system checks each IC to determine whether the set-point has been exceeded. If so, it characterizes the IC by that set-point; if not, it decrements the set-point and checks again. The method continues until all ICs have been characterized to a specific set-point. As a result of the method, a junction temperature is obtained for each IC. In addition, a real-time estimate of the burn-in time for each IC is obtained, so that burn-in time can be adjusted to maximize burn-in throughput. Apparatus for implementing improved IC burn-in is also described.

    摘要: Downstream synchronous multichannel (DSSM) communications are provided among a plurality of carriers, each being a completely DOCSIS™ 2.0-compliant downstream. The synchronous multichannels support communications with both DSSM-capable communications nodes and non-DSSM-capable communications nodes (e.g., legacy cable modems). Non-DSSM packets are transmitted on a single channel. DSSM packets are split into multiple pieces, which are transmitted simultaneously on all available channels. Since the physical delay variation (e.g., group delay change) across the adjacent carriers is small (on the order of a symbol time), the multiple pieces arrive at the receiving communications nodes at nearly the same time and can be reassembled with minimal buffering and no packet ordering problems. To avoid causing trouble for the non-DSSM-capable communications nodes, the packet pieces are encapsulated with a header that causes the non-DSSM-capable communications nodes to silently discard them.
