  • Patent number: 10764532
    Abstract: Unlike conventional methods and systems for locating ingress, which only monitor the upstream path, a method and system of locating ingress by monitoring the downstream path is provided. A test system measures the signal quality in the upstream path and in dependence upon a noise level being above a predetermined limit, polls a plurality of terminal equipment devices to return a downstream signal quality measurement. The test instrument analyzes the downstream signal quality measurements to locate an ingress source contributing to the noise.

  • Patent number: 10601465
    Abstract: Non-disruptive sweep measurements using low power coherent signals overcome the limitations of prior art frequency response systems for cable networks. Modulated or unmodulated, e.g. continuous wave (CW), test signals are transmitted into the network at a first or input point (input point is in the head end for forward sweep; input point is in the field for reverse sweep). The test signals are transmitted continuously at multiple frequencies, so as a composite they form a wideband, OFDM-like (orthogonal frequency-division multiplexing) waveform. A receiver at a second or output point generates power reading measurements, from which the frequency response of the network is produced.

  • Patent number: 10528206
    Abstract: First to third electrode layers (1) are laminated. A dielectric (22) disposed between the second and third electrode layers can be elastically deformed by pressing force from the first electrode layer-side to reduce distance between the second and third electrode layers. The first electrode layer is composed of first electrodes (Rxc) along a first direction (X). The second electrode layer is composed of second electrodes (Txcf) along a second direction (Y) intersecting the first direction. The third electrode layer is composed of third electrodes (Rxf) along a third direction (X) intersecting the second direction. During position-detection, the second electrodes (Txcf) function as transmission-side position-detection electrodes and the first electrodes function as reception-side position detection electrodes to constitute a mutual-capacitance touch panel unit (31).

  • Patent number: 10404388
    Abstract: A signal leakage in a cable network may be detected by using a test device to obtain a spectrum of an electromagnetic wave propagating in vicinity of the cable network, and automatically detecting QAM channels in the obtained spectrum by detecting characteristic spectral roll-offs at boundary frequencies between QAM channels of the cable network. A test device may be used to determine which QAM channels are currently active on the cable network, thereby facilitating automatic QAM signal leakage detection.
