摘要： A wireless communication device capable of determining its location in an indoor environment is disclosed. In an indoor environment, a wireless communication device may have insufficient access to GNSS satellites or cellular towers to make an accurate determination as to its location. Therefore, the wireless communication device generates a fingerprint map of the environment by estimating its position and scanning multiple positions within the environment for accessible access points and characteristics. The device stores this information in memory, which it can later refer to for determining its current position.

摘要： A wireless communication device capable of more accurately estimating its location in an indoor environment is disclosed. In an indoor environment, the wireless communication device may seek to generate a fingerprint map so as to later identify its location within the environment. However, the map requires the device to at least estimate its current position. Therefore, the device includes one or more sensors to identify each of a bearing and a speed of the device. For example, the speed may be determined based on sensed steps and a stored step length. This information may then be used to estimate the device's location as it moves through the indoor environment.

摘要： A system and a method for routing an instant message which can refer to a Converged IP Messaging (CPM) message are provided. The instant message, for example, CPM message and the like, is sent to a plurality of terminals having the same user identification of the same user; in the case that the receiving party uses a plurality of terminals online simultaneously, the communication system such as a CPM system routes the instant message such as CPM message to a plurality of terminals respectively. Thereby, the problem of routing when forwarding an instant message such as a ‘one number more machines” CPM message can be solved, further, the transmission of messages in the communication system such as the CPM system is realized better, and improving the user experience.

摘要： The present invention provides a method and system for transmitting a large message mode CPM message. A MSRP link is created respectively between a CPM client at a sending end and a participating function entity at a source end, between the participating function entity at the source end and a CPM control function entity, and between the CPM control function entity and an inter-working function entity based on a media negotiation process before the CPM client transmits a large message mode CPM message to a non-CPM system receiver in a target group; then, the CPM client at the sending end sends the contents of the large message mode CPM message to the inter-working function entity through each created MSRP link sequentially; and the inter-working function entity sends the received contents of the large message mode CPM message to the non-CPM system receiver after performing protocol conversion on the received contents. The method and the system solve the problem that a large message mode CPM message cannot be transmitted to a group in the prior art and the user experience is improved.

摘要： A proxy-based thin-client web browsing framework enables cooperative web browsing of multiple devices. The multiple devices may include devices that are not intended for web browsing and have limited or no web browsers and/or user input capabilities. The proxy-based thin client web browsing framework employs a virtual browser at a proxy server to perform all browser-engine logics, and retrieve, render and encode web pages on behalf of the multiple devices. The multiple devices therefore only need to have limited decoding and display capabilities to perform web browsing. The proxy-based thin client web browsing framework further includes a touch controller as a remote controller for a device that has no or limited user texting or manipulating capabilities.

摘要： A method for compressing a high dynamic range (HDR) texture. A first block of texels of the HDR texture in a red-green-blue (RGB) space may be transformed to a second block of texels in a luminance-chrominance space. The first block may have red values, green values and blue values. The second block may have luminance values and chrominance values. The chrominance values may be based on a sum of the red values, a sum of the green values and a sum of the blue values. The luminance values and the chrominance values may be converted to an 8-bit integer format. The luminance values may be modified to restore a local linearity property to the second block. The second block may be compressed.

摘要： Techniques describe providing a web page for a proxy-based browser on a mobile device to enhance user experience. A proxy server receives a layout of the web page, extracts web elements from the web page, and captures images of the web elements of the web page. The web elements are incorporated with a background screen image to form a composite screen format to represent a display of the web page. The background screen image is compressed by splitting an encoded frame into fixed-size slices and splitting a previous screen frame into fixed-size slices. The proxy server provides the web page synchronized with the mobile device based on the composite screen format and the compressed background screen image. Furthermore, the proxy server receives input from a user to provide updates to web elements that are dynamic on the web page to be displayed on the screen of the mobile device.

摘要： Image resizing for web-based searching is described. In one implementation, a system resizes a user-selected thumbnail image into a larger version of the image that emulates the quality of a large, original image, but without downloading the original image. First, the system extracts resizing parameters when each thumbnail image is created. Then, the system creates a codebook of primitive visual elements extracted from a collection of training images. The primitive visual elements in the codebook provide universal visual parts for reconstructing images. The codebook and a resizing plug-in can be sent once to the user over a background channel. When the user selects a thumbnail image for enlargement, the system resizes the thumbnail image via interpolation and then refines the enlarged image with primitive visual elements from the codebook. The refinement creates an enlarged image that emulates the quality of the large, original image, without downloading the original image.
