  • Patent number: 9000919
    Abstract: A solar panel system includes a plurality of the panels connected together in one or more panel strings. An embodiment includes a signal generator module connected to the photovoltaic panel strings injecting a multiple radio frequency signal onto each of the strings and a detector module analyzing a frequency response echo from the panel strings. The signal generator may include a string coupling module communicating with a controller. The detector module analyzes the echo to obtain an analog fingerprint for each panel string and determine whether the fingerprint for each panel string is within an acceptable range. The detector module initiates an alarm when one of the fingerprints is outside the acceptable range. During night time, when no current is being produced by the photovoltaic cells, a DC or AC source may be connected to the panel strings to inject a signal onto the strings for the same purpose.

  • Patent number: 8947282
    Abstract: A current controller includes impedance elements coupled to form at least one impedance ladder circuit which exhibits a fixed impedance at an input and current divider steps each differing in a current magnitude by a multiple of three with respect to the current magnitude in an adjacent less significant step. Single pole triple throw (SPTT) switchably couple an associated step in the impedance ladder circuit to one of three outputs. Three discrete current sources or sinks are each coupled to a corresponding one of the outputs of each of the SPTT switches. The digital driver is coupled to each control input of each SPTT switch to additively deliver selected ones of the stepped currents from each step of the impedance ladder circuit to a corresponding selected one of the current sources or sinks.

  • Patent number: 8345859
    Abstract: A XDSL line card including an allocator for allocating power to the multi-tone modulated communications on each of the subscriber lines, and for selecting control parameters sufficient to effect communications on each of the subscriber lines at a power level proximate to an allocated power level therefore. The line card also includes configurable components coupled to one another to form a transmit path and a receive path to couple to the digital subscriber lines. The configurable components are responsive to the control parameters selected by the allocator to initialize multi-tone communications over each of the plurality of subscriber lines at a power level proximate the allocated power level.

  • Patent number: 8036293
    Abstract: A transceiver having shared and discrete components forming a transmit path and a receive path configured to couple to a communication medium for establishing a multi-tone modulated communication channel thereon. The transceiver includes a line driver component on the transmit path. The line driver is configured to respond to a protocol determination and by configuring at least one of a transmit power level and a transmit bandwidth of the multi-tone modulated communication channel on the communication medium. The line driver includes a plurality of pre-amplifiers each exhibiting a combination of transmit power and bandwidth for amplification of a transmit signal modulated with a selected multi-tone modulation protocol. The line driver also includes a single output amplifier having an output coupled to the communication medium and an input switchably coupled to an output of a selected one of the plurality of pre-amplifiers in response to the protocol determination.

  • Patent number: 6489768
    Abstract: A double tuned probe for employment in NMR apparatus includes a first resonant circuit of normal phase conductor coupled to the sample and also in communication with a second circuit containing a component in a superconductive phase. Communication between the two circuits supports two RF channels which may be exhibit relative sensitivities in proportion to their relative Q values.
