Upstream signal quality monitoring
The problem is that a measurement of the average signal quality (average modulation error ratio), does not identify poor quality signals that may be originating from an individual cable modem. The device of the present invention displays the modulation error ratio (MER) for each packet received.

Method for facilitating latency measurements using intermediate network devices between endpoint devices connected by a computer network
Network latency measurements of RTP traffic are measured using an intermediate network device positioned between endpoints that do not necessarily support RTCP. During an active RTP stream between two endpoints, the intermediate device detects whether the endpoints are already providing their own RTCP packets and responding to RTCP packets from the other endpoint. If not, the intermediate device generates RTCP packets on behalf of the non-responsive or non-providing endpoint(s), acting as a proxy for the endpoint(s), so the packets appear to one endpoint as if they were generated by the other endpoint. Thus, if at least one endpoint supports RTCP, a single intermediate device is sufficient to generate the RTCP packets that allow the latency calculation to be performed. |

Non-volatile memory and method with continuous scanning time-domain sensing
A page of non-volatile multi-level memory cells on a word line is sensed in parallel by sense amps via bit lines. A predetermined input sensing voltage as an increasing function of time applied to the word line allows scanning of the entire range of thresholds of the memory cell in one sweep. Sensing of the thresholds of individual cells is then reduced to a time-domain sensing by noting the times the individual cells become conducting. Each conducting time, adjusted for delays in the word line and the bit line, can be used to derive the sensing voltage level that developed at the word line local to the cell when the cell became conducting. The locally developed sensing voltage level yields the threshold of the cell. This time-domain sensing is relative insensitive to the number of levels of a multi-level memory and therefore resolve many levels rapidly in one sweep. |

Malfunction detection with derivative calculation
Systems and methods of detecting occlusions and fluid-loss conditions (e.g., disconnects and/or leakages) in an infusion pump are discussed. For example, electrokinetic infusion pumps may develop an occlusion in the fluid flow path, which can disrupt control of fluid dispersed from the pump. As well, an infusion set disconnect can also result in a fluid-loss that can be disruptive. Such disruptions can be troublesome to systems that control the infusion pump, such as closed loop controllers. Accordingly, systems and methods described herein can be used to detect such occlusions and fluid-loss conditions during infusion pump operation. For example, a position sensor can be used to monitor fluid flow from the infusion pump, with the measurement being compared with an expected value to detect an occlusion or fluid-loss condition. Other algorithms for utilizing the position sensor are also described. |

Anticancer agents based on regulation of protein prenylation
Oncoproteins such as Ras and RhoB are known to induce cell division in an unrestrained manner when such proteins are localized at the inner surface of a cancer cell membrane.
