Abstract: A system includes a controller that is in communication with a medication delivery device and that includes control logic. The control logic is operative to calculate a first filtered total daily dose (TDD) during an initial tracking phase based, at least in part, on a first set of insulin delivery doses and subject to a first set of rate limits. The control logic is also operative to calculate a second filtered TDD during a steady state tracking phase based, at least in part, on a second set of insulin delivery doses and subject to a second set of rate limits.

Abstract: A dual-port testing apparatus is provided for testing a cable network at two test points. The testing may comprise demodulation of a same data packet at the test points, decoding the data packet, performing spectral analysis of the signal, etc. Testing results may be correlated with one another, both visually and by using pre-defined test metrics comprising a weighted sum of demodulation and decoding parameters such as modulation extinction ratio and a codeword error.

Abstract: Systems and methods for quantifying the suitability of a coax network segment to support MoCA communications, comprising: transmitting a test signal associated with MoCA communications through the segment's first end; receiving the test signal through the segment's second end; determining a response function; determining a channel degradation reference based on the highest power level of the response function and a predetermined reference; calculating subcarrier degradation for each MoCA subcarrier, in accordance with the difference between the channel degradation reference and the subcarrier response function; and quantifying the suitability of the segment to support MoCA communications from the first end to the second end in accordance with the subcarrier degradation of all subcarriers in the response function.

Abstract: A method of characterizing a wiring network is implemented in a system which includes a test controller and at least two probes. On commands from the test controller, at least one of the probes changes its impedance between the nominal impedance of the wiring network and a mismatch impedance. Reflectometry measurements are performed before and after of switching the impedance of the second probe. At the first probe, an RF signal is generated and a reflected signal is measured. Then, the impedance of the second probe is changed, and again an RF signal is generated and a reflected signal is measured at the first probe. Additionally, a frequency response may be measured at the second probe. The results of the measurements are used for characterization of a transmission line between the first and second probes.

Abstract: A method for determining a contribution of burst noise to a bit error rate in a digital system for reception of an interleaved forward error correction-enabled digital symbol stream is described. The method is based on identifying errored symbols at a decoding stage, determining their positions in the interleaved stream, and performing a windowing operation such that the errored symbols located within the window in the interleaved stream are designated as burst errored symbols. A corresponding digital receiver and a digital transmission system are also disclosed.

Abstract: In order to measure the performance of a DOCSIS upstream channel as well as to locate impairments, a special test signal is transmitted in a time slot of the upstream channel by a test instrument positioned anywhere within the CATV plant. A second test instrument, located at the termination point of the upstream plant, then detects, recovers, and processes the test signal in order to complete the measurement. The typical methods used to detect and recover bursted signals within a DOCSIS upstream channel use precise timing information transmitted in a corresponding DOCSIS downstream channel. Unfortunately, the downstream channel and thus the precise timing information are not always available to the secondary test instrument. The present invention also describes an apparatus and method for detecting a bursted test signal without the use of the DOCSIS upstream channel timing.
