  • Patent number: 8769327
    Abstract: A battery charger management system/method implementing indirect execution of battery charging profiles is disclosed. The system utilizes a power source control unit (PSCU) to selectively switch a power supply source to a battery charging power supply (BCPS) that charges a battery. A power monitor control unit (PMCU) monitors the current consumed by the BCPS and reports this to the PSCU. The BCPS current consumption provides the PSCU a profile of the charging characteristics of the battery attached to the BCPS, allowing identification of the battery type and a determination of the optimal charging profile for the battery in its current charge state. The power source to the BCPS is switched by the PCCU in accordance with the determined optimal charging profile to optimally charge the battery. The PSCU may operate independently or in conjunction with wireless commands received from a mobile communication device (MCD).

  • Publication number: 20140101476
    Abstract: A battery management system/method implementing optimal dynamic battery charge/discharge cycling is disclosed. The system utilizes a power source control unit (PSCU) to selectively switch a power supply source to a battery charger that charges a battery servicing a portable computing device. The PSCU is controlled by a power monitor control unit (PMCU) that monitors the battery state and determines the optimal charge/discharge profile for the battery. Depending on the type and current condition of the battery as well as battery charge/discharge history, the PMCU monitors the historical, current, and/or anticipated demand activity of the battery to determine an optimal charge/discharge profile for the battery to enable maximum battery life under a wide variety of environmental and use profiles. Present invention methods control battery charge/discharge activity based on computing device historical/anticipated use characteristics, battery chemistry, and/or optimal battery lifecycle operation.

  • Patent number: 8666560
    Abstract: A power control system/method implementing Internet based access to hybrid home automation networks is disclosed. The system utilizes a smart gateway power controller (SGPC) to selectively switch an AC power source to a load device under control of local or remote network commands that may be routed through a variety of network interfaces and protocols present within home or other structure-local communications network. SGPC configurations may be nested within a home automation network to permit separation of control for load devices within a common home automation environment. Present invention methods may include routing protocols between disparate home automation networks as well as remote access protocols that permit control of disparate home automation networks via the Internet using a wide variety of remote access interfaces including mobile devices, tablet computers, laptops, desktop computers, and the like.

  • Publication number: 20130261774
    Abstract: A security monitoring system/method implementing distributed Internet-based environmental monitoring and control is disclosed. The system utilizes a smart gateway power controller (SGPC) configured for new/retrofit installation into electrical power distribution networks to allow controlled connection of an AC power source to a customer load device under direction of local or remote Internet direction. The SGPC may also be configured with sensors to detect motion, audio, video, visual images, smoke, carbon monoxide, carbon dioxide, light/darkness, and other environmental data. The SGPC may be configured using a local web-based graphical user interface (GUI) to relay collected sensor information to a remote web browser hosted on a remote computing device. The GUI may incorporate a configuration/setup interface allowing mapping of sensor data to information associated with the sensor location and triggered security reports to occur based on collected sensor data.

  • Publication number: 20130231796
    Abstract: A light fixture monitoring/control system/method allowing a lamp associated with a lighting fixture to be controlled in response to localized lighting fixture sensor inputs and/or remote wireless commands is disclosed. The system utilizes a light fixture adapter (LFA) as a dimming control and monitoring interface between a light fixture and the lamp installed in the LFA. Dimming control is directed by a computing device based on a LFA program (LFAP) that analyzes information from one or more sensors integrated within the LFA. The LFA supports a web-based browser interface and a wireless communication link allowing remote users to define the LFAP and/or directly control lamp dimming and/or access data from LFA sensors. The LFA permits low-cost retrofitting of existing light fixtures with “smart” networked lighting controls that may incorporate advanced spatially diverse security monitoring functions including audio and/or video surveillance.
