A system and method for managing a population of RFID tags. In various aspects, an RFID reader implements one or more RFID protocols to execute a read cycle that defines a series of actions for the RFID reader to perform. The read cycle may begin by the RFID reader broadcasting a query to deselected RFID tags to generate a list of deselected tag identifiers. The read cycle then causes the RFID reader to broadcast a query to selected RFID tags to track selected RFID tags. Finally, the read cycle causes the RFID reader to broadcast a selection command that includes the list of deselected tag identifiers.

An information collection system includes a plurality of radio tags and a reading device. Each of the radio tags stores identification information and includes a sensor, an antenna that receives a carrier wave from the reading device, and a data transmission unit that sends measurement data including the identification information and information obtained by the sensor to the reading device after the carrier wave is received by the antenna. The plurality of radio tags send the identification information and the information obtained by the sensor with different natural periods from the data transmission units. The reading device transmits the carrier wave to each of the radio tags, receives data from each of the radio tags, and obtains the data.

Energy remains a critical challenge for continuous sensing: with low-capacity batteries, wearable devices require frequent charging. In contrast, installing sensors in everyday smart objects, such as kitchen cabinets, household appliances and office equipment, supports ADL detection via indirect observations on human interaction with such objects, but cannot provide individual-specific insights in multi-tenanted environments. The embodiments herein provide a method and system for energy efficient activity recognition and behavior analysis. Architecture disclosed utilizes a hybrid mode of inexpensive, battery-free sensing of physical activities performed by a subject been monitored during his Activities for Daily Living (ADLs). The sensing combines object interaction sensing with person-specific wearable sensing to recognize individual activities in smart spaces. The method and system disclosed quantifies a probabilistic approach that uses longitudinal observations of user-item interactions, over each individual episode, to compute the anomalous behavior of the subject.

Response parameters for a population of RFID tags present in an inventory space are determined by (a) continuously scanning the inventory space to interrogate the population of RFID tags and receiving responses from RFID tags within the population; (b) after multiple responses have been received from a specific RFID tag, determining response times for the specific RFID tag corresponding to time periods between sequential ones of the multiple responses from the specific RFID tag, (c) calculating a maximum acceptable response time based at least in part on the response times determined in step (b); and (c) recording a response interval data set including one or more of the response times determined in step (b) and the maximum acceptable response time calculated in step (c).

An operating method of a card reader supporting high-speed data communication. The method comprises: if a card reader determines that a first in-place flag is not valid, then the card reader sends a card query instruction in a contactless field, sends a speed adjustment configuration instruction to a contactless card upon receiving of query response data returned by the contactless card, and determines whether response data indicating successful speed adjustment configuration and returned by the contactless card is received; and if so, then the card reader configures communication speeds thereof, such that a received first instruction is sent to the contactless card with a first communication speed, and an operation result returned by the contactless card is received with a second communication speed, otherwise the card reader configures the communication speeds thereof, such that a received first instruction is sent to the contactless card with a third communication speed, and an operation result returned by the contactless card is received with a fourth communication speed, wherein the first communication speed is greater than the third communication speed, and the second communication speed is greater than the fourth communication speed. The above method can shorten interaction time between a contactless card reader and a contactless card, thereby improving user experience.

An RFID apparatus for communicating with at least one RFID transponder is provided that has an RFID transceiver for radiating and receiving RFID signals and a control unit that is configured to encode RFID information into the RFID signal in accordance with an RFID protocol or to read it from the RFID signal and in which a singulation process is implemented to give a command to only one respective RFID transponder. The singulation process in this respect checks a communication parameter of the RFID signal itself that is independent of RFID information encoded in the RFID signal.

A method includes storing a user address associated with a particular user of a device in a first transceiver identification field stored on a first identification tag of a first smart object of a first type. An interrogator of the device is enabled to read a second identification tag attached to a second smart object of the first type. A second transceiver identification field is stored on the second identification tag. The user address is stored in the second transceiver identification field using the interrogator responsive to determining that the second radio identification field has a default value. A connection is established between the device and the second smart object using a first transceiver of the device based on the user address.
