Home automation system and method

A home automation system and method for automatic control of controlled devices throughout a home. A unique architecture of occupancy sensors includes entry/exit sensors for detecting movement through doorways that separate rooms in the home, room motion sensors for detecting room occupancy, spot sensors to detect occupancy of specific locations within the rooms, and house status sensors to detect the status of certain parameters of the home. A central controller communicates with the sensors and controlled objects over a communications network, where the sensors and controlled objects can be added to the system in a ‘plug and play’ manner. The central controller controls the controlled objects in response to the entry/exit sensors, room motion sensors, spot sensors and the house status sensors. This control is accomplished by assigning each room to one of a plurality of room occupancy states, and to one of a plurality of room modes for creating desired room atmospheres using the controlled objects, which both dictate how the controlled objects are controlled by the central controller. The room modes travel from room to room as the occupant moves throughout the home, and multiple occupants can be using different room modes as they move about the home. The controlled objects also have controlled object states, which are used by the central controller to control the controlled objects.

In-vehicle device for wirelessly connecting a vehicle to the internet and for transacting e-commerce and e-business

An in-vehicle device data communicates with Internet based data processing resources for the purpose of transacting e-mail, e-commerce, and e-business. The in-vehicle device and the Internet based data processing resources can effectuate a wide variety of e-mail, e-commerce, and e-business including accessing auto part databases, warranty, customer, and other remote databases. In addition, e-mail, e-commerce, and e-business transactions can include vehicle security and vehicle service management, data communicating Internet based radio, audio, MP3, MPEG, video, and other types of data. Furthermore, e-mail, e-commerce, and e-business transactions can include interactive advertising, promotional offers, coupons, and supporting other remote data communications.
The in-vehicle device can also include functionality for remote monitoring of vehicle performance, data communicating and accessing remote Internet based content and data, and effectuating adjustments and control of vehicle operation. Remote monitoring and control of vehicle operation can be by way of an Internet based data processing resource and can include engine control system programming and setting adjustment, vehicle monitoring, and transmission of vehicle telemetry and metric data. Vehicle telemetry and metric data can include global positioning system (GPS) data, vehicle operational data, engine performance data, and other vehicle data.
The in-vehicle device can also wirelessly data communicate with a communication interface device (COM device) or an Internet appliance. Such COM devices or Internet appliances can data communicate wirelessly with an in-vehicle device and simultaneously data communicate in a wired or wireless mode of operation to Internet based data processing resources, and to other data processing resources.

Methods and apparatuses for using mobile GPS receivers to synchronize basestations in cellular networks

Methods and apparatuses for synchronizing basestations in a cellular network. One exemplary method performs time synchronization between at least two basestations, a first basestation and a second basestation, of a cellular communication system. In this exemplary method, a first time-of-day and a first geographical location of a first mobile cellular receiver station (MS) are determined from a first satellite positioning system (SPS) receiver which is co-located with the first MS, and the first time-of-day and first location are transmitted by the first MS to a first basestation which determines a time-of-day of the first basestation from the first time-of-day and first location and from a known location of the first basestation. Also in this exemplary method, a second time-of-day and a second geographical location of a second MS are determined from a second SPS receiver which is co-located with the second MS, and the second time-of-day and the second location are transmitted to a second basestation which determines a time-of-day of the second basestation from the second time-of-day and the second location and a known location of the second basestation. Other methods and apparatuses are also described for synchronizing basestations in a cellular network.

Using a derived table of signal strength data to locate and track a user in a wireless network

A method for locating a user in a wireless network is disclosed. A mobile computer seeking to determine its location within a building detects the signal strength of one or more wireless base stations placed at known locations throughout the building. The mobile computer uses this measured signal strength to determine its location via a signal-strength-to-location table look-up. A table of known locations within the building and the base station signal strength at those locations is searched to find the most similar stored signal strength to the signal strength detected. The location corresponding to the most similar stored signal strength is determined to be the current location of the mobile computer. Alternatively, a number of signal strengths from the table can be used and the corresponding locations can be spatially averaged to determine the location of the mobile computer. The table can be derived empirically, by placing a mobile computer at the known locations and detecting the signal strength of the wireless base stations at those locations, or the table can be derived mathematically by taking into account a reference signal strength, the distance between the reference point and the known location, and the number of walls between the reference point and the known location. As an alternative, the base stations can detect the signal strength of the mobile computer. In such a case, the table would relate a known position of the mobile computer to the signal strength of the mobile computer at that location as detected by the one or more base stations.
