    摘要: Wireless sensing units, methods, systems, and processor-readable media for obtaining pressure data relating to one or more pressure locations of a surface area are described. A wireless sensing system includes a pressure monitoring device communicating with modular wireless smart floor tiles using RFID, either using an RFID reader or wireless network interface (e.g., 802.11). The tiles incorporate passive or active RFID tags. The tiles can be powered wirelessly, e.g. by a built-in piezoelectric power unit or by a wireless power source using magnetic resonance. A data capture circuit in each tile collects and saves the data for transmission to the floor pressure monitoring device. Various software applications can be enabled by the smart floor system, including fall detection and prediction, gesture input, intrusion detection, and user location tracking for smart home automation.

    摘要: Digital records are clustered and assigned unique individual identity across a plurality of data sources. Each record contains one or more tagged common properties, which belongs to an underlying identifiable entity. A special parameterized metric distance is calculated for all pairs of records. With adjustment of the metric parameters, the records are clustered based on a predetermined distance threshold. Based on the clustered records, the underlying identity associated with the records can be resolved.

    摘要: A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by controlling and separating the LTE signaling and the non-LTE signaling using dedicated time intervals to separate LTE signaling from non-LTE signaling. In addition, coexistence mode handover procedures are provided which use threshold-based triggering events to avoid coexistence interference and to prevent ping-pong effects by establishing a “keeping time” parameter so that a non-interfering network node does not switch back to an interfering network node after handoff. Coexistence interference is also avoided by providing a hybrid automatic repeat request (HARQ) mechanism which accounts for coexistence interference by providing a fixed or variable on-interval parameter and an activity parameter indicating whether non-LTE activity is present to maximize a time interval for non-LTE devices without interference from LTE activity on the same device.
