Abstract: In certain embodiments, a method includes accessing, in response to a request to monitor a host device, a first set of discovery information associated with the host device. The first set of discovery information indicates at least one characteristic of the host device. The method further includes determining, based on the first set of discovery information, a second set of discovery information associated with the host device. The method also includes determining, based on the first and second sets of discovery information and based on one or more pre-defined rules, a metric associated with the host device to be monitored. The method includes communicating, based on the metric to be monitored, an installation package to the host device. The installation package includes a probe that is configured to monitor the metric.

Abstract: A voltage signal and a wetting current are received from a switching device. A first pulse train is created from the voltage signal and the first pulse train has a first duty cycle that is proportional to the voltage at the switching device. The first pulse train is transmitted across an isolation barrier. The first pulse train that is received across the isolation barrier is digitized and at least one operating condition of the switching device is determined based upon the digitized pulse train. A second pulse train having a second duty cycle is received and the wetting current from the switching device is controlled based upon the second duty cycle.

Abstract: A voltage from a switching device across a plurality of attenuation paths is received. Each of the attenuation paths provides a different attenuation to the voltage from the others. At embedded control logic, at least one of the plurality of attenuation paths is chosen and a sensed voltage is determined according to the at least one attenuation path that is chosen.

Abstract: An RF modem used with a host device for transmitting information to, and receiving information from, other host devices. Prior to a transmission, the information is Manchester encoded and transmitted by On/Off Keying. A superregenerative receiver circuit (which may also operate as the transmitter) operating at the transmitted frequency detects the transmitted information. The information is recovered in conjunction with a timing function which times the buildup of RF energy within the receiver circuit so that a transmitted binary 1 can be distinguished from a binary 0. For use in a system with a plurality of hosts, multiple channels of operation are provided. In order to conserve power, the apparatus is operated in a power saving, sleep or scanning mode, as well as a full power active mode.
