Implantable systems for controlling flow through body lumens comprise a control module and an actuator. The actuator is implanted at least partially over the body lumen to selectively constrict the lumen and control flow therethrough. The control module includes at least a power source for operating the actuator and a remotely operated switch for controlling the power source. Usually, the control module will have programmable circuitry for adjusting on / off time, degree of closure, and the like. The switch of the control module is remotely actuated by a magnetic or other signal. The control circuitry may be remotely programmed using a hand-held programmer.
A single communication interface for controlling multiple smart appliances. The communication interface can be integral with an appliance and have a port for communicating with at least one other appliance or energy consuming devices. The communication interface can be a separate module connectable to a plurality of appliance or energy consuming devices. A wireless or wired connection can be established between the communication module and an energy management device for controlling the smart appliances or energy consuming devices connected to the communication module. One or more of the appliances or energy consuming devices can be wirelessly connected to the communication interface.
