  • Publication number: 20200065879
    Abstract: A system recommends home devices to users. The recommended home devices are identified based at least on the environment where the home devices are to be placed. The system analyzes images representing the environment where a home device is to be placed. Characteristics of the environment are analyzed and used to identify home devices that are compatible with the environment. The system may employ one or more machine learning models to analyze the images. The recommended home devices can be further identified based on users' specification for home devices and/or users' profiles. The system provides previews of the recommended home devices to users such that the users can review placement of the home devices in the environment.

  • Patent number: 6862494
    Abstract: An automated cooking system (10) cooks food (12) accompanied by machine-readable indicia, such as a bar code (16) read by a reader (18). Cooking data, including function coefficients, are accessed from an Internet server (20) based on the information in the bar code. An oven (40) cooks the food in phases in response to the cooking data and one or more monitored food parameters of humidity, temperature and weight. The cooking is controlled by functions in which one or more food parameters are multiplied by coefficients that vary according to food type.

  • Patent number: 6826267
    Abstract: Appliances (102, 102, 106 and 108) are controlled by providing a source (2016, 112) of command fields (CMD, FIG. 2) that include a context subfield (Community, FIG. 4) defining operating modes and a command subfield (Command, FIG. 4) defining operations to be performed within the context subfield. A network (119) transmits the command fields between the source and the appliance. A controller (112, 116) processes the command fields so that an operation defined by one of the command subfields is performed.
