  • Patent number: 8299932
    Abstract: In a closed-loop monitoring system, a host device is operable to output encoded signals at a coupling side to a single transmission line. Each of monitoring devices includes: a current inducting generating unit generating induced encoded signals when the encoded signals pass through a signal current generating element coupled across an input side coupled to the transmission line; a control unit identifying a monitoring signal from the induced encoded signals generated by the current inducting generating unit; and a detecting unit detecting, in response to the monitoring signal, whether each of electronic devices coupled thereto is activated ox deactivated and transmitting a reply signal associated with states of the electronic devices to the transmission line based on a detection result made thereby. The host device receives the reply signal from each monitoring device through the transmission line and the coupling side to obtain state information associated with the electronic devices.

    Abstract: A characteristic tracking method for a battery module including at least one battery is disclosed. A look-up table is provided according to a primary characteristic of the battery. It is determined whether a battery has satisfied a preset condition when the battery module is operated from a usage state to an idling state. The battery is measured to have obtained a first voltage and a real capacity when the battery satisfies the preset condition. The measured first voltage is utilized to locate a table capacity of the battery from the look-up table. The look-up table is updated according to the real capacity and the table capacity. A peripheral circuit of characteristic tracking method has been exhibited.
