A system includes an electric appliance, which is operated with replaceable and rechargeable batteries, a charging station and two or more battery units. The charging station has two or more receptacles for holding and charging the battery units. A first coupling is provided between a battery unit and the appliance and a second coupling is provided between a battery unit and the charging station such that a battery unit connected to the appliance can be uncoupled from the appliance by one-handed operation and can be coupled to the charging station for charging by one-handed operation. Similarly, a battery unit connected to the charging station can be coupled to the appliance and uncoupled from the charging station by one-handed operation.

A short-range wireless power transmission and reception system and method are provided. Power is transmitted from the electrical utility mains power supply to electrically powered appliances via electromagnetic radiation. The appliances are capable of receiving the transmitted power, converting it into electricity and storing it for subsequent use, as well as using it directly to power the appliances.

Disclosed herein is a geofence service that enables various remote control and automatic operations based a user's current geographic position as determined by the user's mobile device's current geographic location. The geofence service enables the user to define one or more geofences based on specific geographic locations. Such geofences may be applied against several geofence applications for remote and automatic control of devices. In one embodiment, the mobile device's volume or power control settings are adjusted based on the user's location inside or outside a geofence. In one embodiment, temperature setting of a building or house is controlled based on user's proximity to a geofence. In one embodiment, electrical appliances within a home are activated and controlled automatically based on user's current geographic location.

An integrated remote controller and a main set-top-box therefor, wherein the integrated remote controller performs communication with the main set-top-box of home network system through WLAN and provides appliance control signals to a corresponding appliances connected to the main set-top-box through wires or wirelessly. Every home networked household appliance can be controlled by one integrated remote controller through intuitive and easy user interface, irrespective of where a user is, whereby the user can easily control any appliance, check a control result in response to a control request right away, and check or control the status of appliances through a regular monitoring function. As a result, user mobility, convenience, and functionality can be maximized.

Electrical appliance energy consumption control methods and electrical energy consumption systems are described. In one aspect, an electrical appliance energy consumption control method includes providing an electrical appliance coupled with a power distribution system, receiving electrical energy within the appliance from the power distribution system, consuming the received electrical energy using a plurality of loads of the appliance, monitoring electrical energy of the power distribution system, and adjusting an amount of consumption of the received electrical energy via one of the loads of the appliance from an initial level of consumption to an other level of consumption different than the initial level of consumption responsive to the monitoring.

A method and apparatus for switching AC appliances and lights of residences and other automation systems through SPDT or DPDT relays connected in electrical circuit with SPDT or DPDT switch including a current sensor and/or a status sensor. The operating key of the relay and the key lever of the electric switch can each be used for operating a dedicated appliance or light, a group of appliance and lights and all appliance and/or lights including scenarios setup via the many well known two way, three way or four way light switches, by operating the switch lever or key in multi steps. The SPDT or DPDT relays are operated via RF, IR and fiber optic communicating two way signal for operating the lights and reporting statuses.

Autonomous personal service robot to monitor its owner for symptoms of distress and provide assistance. The system may include sensors to detect situations before they affect people such as smoke, heat, temperature and carbon monoxide sensors. The system can provide security for the home. The PRA may comprise features such as a medicine dispenser and blood pressure cuff. Features such as broadband internet, MP3 player, reading lights and eye glass tracker provide butler type capabilities that enable the system to appeal to markets beyond the elderly and infirmed. The system may also include an X10 transmitter/receiver to automatically control various household lights and appliances. Equipping the system with a robot arm enables the robot to fetch items, turn on and off wall switches and open the refrigerator.

An electrochemical device for moving particles covered with a protein is provided. The device includes at least two electrodes that are in contact with a liquid containing the protein-covered particles and a circuit that generates a potential difference in a range that does not cause electrolysis of the liquid between the electrodes. The particles are moved by electrophoresis in the direction of the arrangement of the electrodes. The invention provided herein has numerous applications, including use in a microorganism concentration condensing device, a blood component induction device, and/or a blood component induction method, and/or an electric appliance that decreases the concentration of microorganisms present on the surface of a heat exchanger.

A voice control system is adapted for controlling an electrical appliance, and includes a host and a portable voice control device. The portable voice control device is capable of wireless communication with the host, and includes an audio pick-up unit for receiving a voice input. One of the host and the portable voice control device includes a voice recognition control module that is configured to recognize a control command from the voice input. The host controls operation of the electrical appliance according to the control command, and transmits an appliance status message to the portable voice control device. The portable voice control device further includes an output unit for outputting the appliance status message.

An electric power monitoring system includes a source monitor for measuring momentary power output of an electric source supplying electric power to a power distribution system having at least one electric load. The momentary power output is compared with a reference load capability for the electric source to determine the ability of the electric source to support additional load, and load capability data is transmitted based on the load capability. At least one load control receives the transmitted load capability data and controls the supply of power to the at least one corresponding electric load based on the load capability data.

A communication device, for connecting one or more electrical appliances to a remote service centre, comprises a control unit (AMC), means (PLG) for connecting the device (HG) to an alternating voltage electric mains network (Vac) and means (SK) for supplying the alternating mains voltage (Vac) to a power supply line of an electric appliance. The device (HG) further comprises first communication means (CSA), prearranged for receiving information possibly generated by the electric appliance and transmitted through the power supply line thereof, second communication means (ZB), prearranged for establishing a connection with a local area network (HN1) and third communication means (GGM), prearranged for establishing a connection with a further communication network, different from the local network (HN1), to which the remote service centre is connected.
