摘要： This disclosure is directed to a dynamic data compression system. A device may request data comprising certain content from a remote resource. The remote resource may determine if any part of the content is identical or similar to content in other data and if the other data is already on the requesting device. Smart compression may then involve transmitting only the portions of the content not residing on the requesting device, which may combine the received portions of the content with the other data. In another example, a capturing device may capture at least one of an image or video. Smart compression may then involve transmitting only certain features of the image/video to the remote resource. The remote resource may determine image/video content based on the received features, and may perform an action based on the content. In addition, a determination whether to perform smart compression may be based on system/device conditions.

摘要： Wireless location identification systems, methods, and devices include a wireless device configured to transmit at least one sonic signal operating on at least one acoustic frequency and to receive at least one echo signal indicative of the at least one sonic signal being reflected by objects in a current location, an audio module configured to measure the received at least one echo signal and process the at least one echo signal to extract attributes of the echo signal and generate at least one echo profile characteristic; and logic configured to compare the at least one profile characteristic with previously-stored sonic characteristics that are correlated with pre-identified locations. The current location is then identified as a pre-identified location correlated to the previously-stored sonic characteristics that match the at least one profile characteristic.

摘要： This disclosure is directed to positioning and mapping based on virtual landmarks. A space may include a plurality of signal sources (e.g., wireless access points (APs), cellular base stations, etc.). The space may be virtually divided into a plurality of regions, wherein each region in the space may be associated with a virtual landmark. Virtual landmarks may be identified by a signature comprised of measurements of wireless signals received from the plurality of access points when at the associated region. A device position may be approximated based on signal power magnitude and variance measurements for wireless signals received at the virtual landmark. Devices may employ an algorithm such as, for example, Simultaneous Localization and Mapping (SLAM) for positioning and map creation in the space without the need for GPS signals, specialized signaling equipment, pre-navigation device training, etc. Navigation/mapping may also account for space changes, signal source position changes, etc.
