  • the home computer or “Thin-Server” can be used to monitor and control the home appliances, including microwaves, ovens and refrigerators, as well as other appliances.
  • the protocol used to control such an appliance from the home server is one that has been developed specifically for the home network communication interface.
  • the communication interface protocol allows one to provide an abstract definition of say an appliance and be able to query it and perform operations on it.
  • Communication interface can operate over many different types of networks, power lines, radio frequency, coaxial cable and twisted pair, as well as others.
  • the Applicant's invention uses existing power lines in an existing home to communicate to the appliances. This avoids retrofitting a home with a new network.
  • Applicant's invention uses object oriented methodologies in many ways. The system is written in an object oriented language. Second, the communication interface protocol is object oriented by design. Each communication interface device is considered an object with attributes that can be interrogated or changed directly via operations or methods.
  • the remote interface is any suitable remote interface known in the art. Essentially, this technology allows one to easily design objects (such as home appliances) in one's home. These objects can be directly manipulated from any computer around the world. The use of the remote interface is an important aspect for the remote operation of the appliance.
  • a remote interface object on the home server is built for each home appliance. These objects take requests from the software to control the appliance. The software could be located locally on the home server or could be remotely located at one's office in another state or country. This allows a homeowner to remotely monitor their home with unprecedented ease and ability.
  • This applet is launched within the browser and provides the means to communicate with remote interface objects on one's home server that controls the home appliances.

  • the software on the home server that controls the home appliance is called the appliance server.
  • the appliance server searches for all home appliances in the home. It does this by broadcasting a communication interface request on the communication media to which all communication interface compliant home appliances respond. Response includes its address on the network, the type, manufacturer and model of the appliances. The appliance server knows, based on the appliances manufacturer and model, how to control the appliance. After discovering all home appliances in the home, the appliance server then creates a remote interface object for each appliance. If the home appliances are powered on after the appliance server has started, the appliance broadcasts an announcement that is received by the appliance server. The appliance is then made available via a remote interface object.
  • the preferred remote interface is as follows.
  • Applicant's software GUI and Applicant's Java applet are two programs that communicate with the remote interface objects in order to control the appliances. These programs are referred to as remote interface clients. Once the client programs connect to these objects, they operate on them as if they were locally defined and created within the client program. The client programs can then use the object's interface to manage the remote appliance. As far as safety is concerned, the remote interface object provides an interface for specifying a safe temperature level. If the temperature of the unit rises above this level, the remote interface object will tell the home appliance to shut down. The object will also notify all client programs that are connected to it that a high temperature condition has occurred. An object can also notify all connected clients if a home appliance has stopped responding to input.
  • the core of software system is the management/GUI software that allows the user to view each home appliance being controlled.
  • Each appliance can be programmed to keep a dish cool until it is time to be cooked. Dishes can be defined by the user which spells out the steps to cook the dish and whether or not it needs to be kept cool before cooking.
  • a major feature of software is the ability to monitor and manage home appliances from remote locations. Applicant's software accomplishes this by providing an appliance server software that runs on the home server. This software is a remote interface server that spawns a remote interface appliance object for each home appliance that it discovers on the home network. These appliance objects continually monitor the real home appliance as well as wait for the GUI software to connect to it.
  • the Applicant's software that connects the appliance objects is referred to as client software.
  • the client software can be run at home on the home server or on another machine in the home.
  • Remote interface objects are inherently distributed. This means that not only can any computer in the home manage home appliances through the remote interface appliance objects, but from any computer in the world, one can monitor and manage appliances in their home.
  • the client software described earlier communicates with appliance objects residing on the home server.
  • the client software is configured with the Internet address of the home server. This allows it to remotely communicate with the home server through the Internet.
  • the client software communicates with the appliance objects through a well known port number.
