摘要： Radio frequency certificates of authenticity (RFCOAs) and associated scanners and methods are presented. In one implementation, an array of miniaturized antenna elements in an RFCOA scanner occupies an area smaller than a credit card yet obtains a unique electromagnetic fingerprint from an RFCOA associated with an item, such as the credit card. The antenna elements are miniaturized by a combination of both folding and meandering the antenna patch components. The electromagnetic fingerprint of an exemplary RFCOA embeddable in a credit card or other item is computationally infeasible to fake, and the RFCOA cannot be physically copied or counterfeited based only on possession of the electromagnetic fingerprint.

摘要： Radio frequency certificates of authenticity (RFCOAs) are presented. In one implementation, a scattering agent is attached to an object to provide a reproducible radio frequency (RF) fingerprint that can be used to authenticate a tag or a seal for the object. In one implementation, the RF fingerprint is measured and digitized, combined with information associated with the object to which the RFCOA is attached, and stored in a radio frequency identification (RFID) system associated with the RFCOA. A scanner receives the fingerprint and the information and authenticates the information by comparing the fingerprint against a new fingerprint obtained from the object.

摘要： A PIFA (Planar Inverted-F Antenna) array antenna has multiple PIFAs. The PIFA array is used to provide different radiation patterns for communication. A signal being emitted by the PIFA array is manipulated. According to the manipulation, the PIFA array may emit the signal with an omni-directional radiation pattern or a directional radiation pattern; the same PIFA array (antenna) is used for both directional communication and omni-directional communication. The PIFA array may be used in mobile computing devices, smart phones, or the like, allowing such devices to transmit directionally and omni-directionally. The signal manipulation may involve splitting the signal into components that feed PIFAs, and before the components reach the PIFAs, changing properties of the components (e.g., phase) relative to each other.

摘要： Human body motion is represented by a skeletal model derived from image data of a user. The model represents joints and bones and has a rigid body portion. The sets of body data are scaled to a predetermined number of sets for a number of periodic units. A body-based coordinate 3-D reference system having a frame of reference defined with respect to a position within the rigid body portion of the skeletal model is generated. The body-based coordinate 3-D reference system is independent of the camera's field of view. The scaled data and representation of relative motion within an orthogonal body-based 3-D reference system decreases the data and simplifies the calculations for determining motion thus enhancing real-time performance for multimedia applications controlled by a user's natural movements.

摘要： The claimed subject matter provides for systems and/or methods for a dynamic range wireless access point to initiate deliberate and/or selective communications with one or more wireless devices over a short range radio path. One embodiment of an access point system comprises a processor that transfers one or more wireless devices to a long range radio path once a transition condition has been met. In another embodiment, an access point system may affect transactions between user/customer's smart devices and a commercial place of business where the access point system and the smart devices initiate communications when the smart devices are deliberately placed within the proximity of the access point antenna and/or the smart devices are brought within the vicinity of the access point antenna such as by passing through the entrance or exit to the place of business.
