A system, apparatus, and method for providing a distributed location based service system to a mobile user. Information related to a particular geographic location may be electronically transferred to a mobile electronic device, without a request from the user, and interpreted locally on the device in the form of a virtual map of location based resources. The mobile device is capable of determining its location using a GPS (Global Positioning System) or a process of measurement and prediction based on calculation. The mobile device can then use the location information and compare it to available location based resources within the device.

A source computer 8 stores updated data that is to be distributed to a plurality of destination computers (12 to 30). The destination computers (12 to 30) are divided into groups sharing a common priority level (5, 4, 3, 2, 1). Each of these groups is then associated with a push update task to be executed by the source computer 8. These push update tasks are then sequentially executed. If a particular group of destination computers exceeds a threshold size, then it may be further divided in accordance with a hierarchy of splitting rules. The push update tasks use multicasting to transfer the update data to the destination computers within their groups in a manner that reduces network traffic.

Systems and methods are described for interactively and graphically interfacing with a user on an HVAC system controlled by a thermostat. The user interface is implemented on a touch screen display on a remote wirelessly connected device such as smartphone or a tablet PC. The interface displays a screen that mimics the display on the thermostat including allowing one or more input methods that are analogous to input methods used on the thermostat. Touch screen gestures such as touch and drag, touch and hold and tapping are used in an intuitive way. The user experience is enhanced by allowing large-scale changes while reducing the risk of sudden unintended changes. The control signals are judiciously tailored to protect the HVAC equipment from unwarranted over-controlling, reduce unnecessary network traffic, and prevent the waste of energy.

A database consisting of at least one fact table and multiple dimension tables is partitioned and distributed across the slave nodes of the database system so that queries are processed in parallel without requiring the transfer of data between the slave nodes. The fact table and a first dimension table of the database are partitioned across the slave nodes. The other dimension tables of the database are duplicated on each of the slave nodes and at least one of these other dimension tables is partitioned across the slave nodes.

A method for compressing a stream of application layer network traffic communicated over a transport layer connection of a virtual private network connection between a client and a server using an appliance. The appliance intercepts one or more transport layer packets of a stream of application network traffic communicated via a transport layer connection of a virtual private network connection between a client and a server. The appliance accumulates data from a payload of the intercepted transport layer packets, determines data accumulated for transmission should be compressed based on one or more compression trigger, and compresses the accumulated data into a self-contained compression block for transmission.

In one embodiment web page response time is improved by requesting multiple resources in a batch request, receiving said resources in a batch response, and disjoining the resources and corresponding HTTP headers before caching on the client. The resources are retrieved by web browser from the cache separately without loss of cache granularity. Client parses base page to determine the embedded resources and includes in the batch requests only web addresses those resources that are uncached or may be expired. To reduce required bandwidth, server validates caching information of every resource before sending the batch response. In another embodiment web application performance for mobile users is improved by combining individually requested resources into the batch response on a network node positioned on a link between cellular network and the Internet.

A data compression method and data communication system utilizing the same includes: a sender apparatus that compares, in response to input of data to be sent, the input data with the previously sent data in storage. The sender apparatus produces, when a data item repeated in the input data and previously sent data is found, delta data by excluding the repeated data item from the input data. The sender apparatus represents the delta data in a transport format, and transmits the delta data. The system includes a receiver apparatus that receives the data in a transport format. The receiver apparatus adds, when delta data is present in the received data, a repeated data item to the delta data, and recovers the original data. The sender apparatus sends and receives data to and from the receiver apparatus through a text-based protocol.

A method and apparatus for providing distributed control of a home automation system is provided. Each device participating in a home automation system is equipped with control logic for providing distributed control. Through the control logic, each device maintains scene definitions describing the state of the device for each scene in which it participates. When any device in the system receives a request to launch a scene, such as a button press on one of the devices, the device broadcasts a scene state change message to all devices within the home automation system. The scene state change message identifies to each device a particular scene that should be launched. Each device in the system receives the message and determines whether the device is a participant in the scene. If the device is a participant in the scene, the device adjusts its state according to a scene definition stored in the device associated with the scene. The device may adjust a controlled electrical load, such as a light, according to the scene definition by turning the load on, off, or setting the load to some intermediate value.
