摘要:
A method for providing unlimited multiplexing of network nodes includes steps of: placing a plurality of tags within a network node, wherein the tags comprise the RuBee long wavelength network protocol; clipping the plurality of tags into separate areas for transmitting and receiving, by placing a plurality of base stations within the network node such that at least one base station overlaps with an adjacent network node; and synchronizing transmit packets from two adjacent base stations transmitting at a same time, such that the tags detect and respond to the packets from a nearby base station and perceive the packets from the distant base station as noise.

A warehousing system includes a container for storing at least one item, a first electronic (e.g., radio frequency identification (RFID)) module associated with the first container, and a controller which wirelessly communicates with first electronic module, for directing a transfer of said at least one item to and/or from said first container. The inventive system may include, for example, a hybrid retail/warehouse system which includes a facility having a shelving area, and a picking area adjacent to the shelving area, and a layout so as to minimize a picking area and a walking distance between a picking area and a shelving area.
摘要:
A method, system, and associated identification device for identification of an entity, such as a passport for identification of national citizens. The identification device includes: a) a display for displaying a photo and other identification data relating to the entity; b) a wireless communication part operable to receive data queries and transmit data wirelessly. The wireless communication portion includes: i) an antenna operable at a low radio frequency not exceeding 1 megahertz; ii) a transceiver operatively connected to said antenna and operable to transmit and receive data at the aforesaid low radio frequency; iii) a data storage device operable to store data including identification data for identifying the entity; iv) a data processor operable to process data received from the transceiver and the data storage device and to send data to cause the transceiver to emit an identification signal based upon the identification data stored in the data storage device; and v) an energy source operable for activating said transceiver and said data processor. The energy source is selected from a rechargeable battery, a replaceable battery, a solar cell, a pair of electrical connectors connectable to a mating pair of connectors extending to a power supply, and a tag energization antenna operable to receive radio frequency energy from an ambient radio frequency field of a second radio frequency.
摘要:
A wireless key (6), capable of transmitting an ultra-low frequency radio wave signal (5), is used to gain access to a secure receptacle (1), the wireless key (6) and receptacle (1) comprising a system to ensure the secure transfer or delivery of items between parties typically engaging in e-commerce. The wireless key (6) possesses a means to discriminate against the unauthorized entry of the receptacle, such as through the use of buttons to enter a secure access code. The wireless key (6) accepts an access code entry from the user desiring entry to the receptacle (1) and subsequently transmits an ultra-low frequency signal (5) to a receiving and processing means (4). If the analysis of the signal indicates the user of the wireless key (6) is authorized to gain entry to the receptacle (1), the receptacle's locking mechanism (3) is disengaged to allow entry.
摘要:
A combination of a patch and a low-frequency (inductive, LF) radiating radio transceiver tag, and antenna system, may be used to track and control electrophoretic/electro-osmotic transdermal drug delivery systems and provide fill data logs of use without complex belts that are worn by the patient or other patient-based attachments.
摘要:
A sturdy radio tag has an antenna and semiconductor chip tuned to low frequency, encapsulated using a low-temperature, low-pressure, low-viscosity injection molding process.
摘要:
An RFID tag in a receptacle is active and includes a microprocessor, a data storage device operable to store a selected code (e.g. an ID code to identify said object or said product), the object including a display for displaying the aforesaid selected code upon a signal from the microprocessor and an energy storage device (e.g. a lithium ion battery), operable to energize the microprocessor, the display, and the transmitter. The tag has an antenna having a dimension thereof that is substantially as large as to a maximum dimension of receptacle.
摘要:
A networked card for identifying and tracking animate and inanimate objects and personnel, the card including: a radio frequency modem operable at a low radio frequency not exceeding one megahertz, the modem including a full duplex transmitter and receiver; a loop antenna operatively coupled with the radio frequency modem, the antenna operable within a range of hundreds of feet; a programmable microprocessor operatively coupled with the radio frequency modem and fully programmable within a network; a memory operatively coupled with the programmable microprocessor, the memory holding identification data; and a battery for providing power to the microprocessor.
摘要:
A method for identifying, tracking, and monitoring a firearm includes steps of: attaching a low frequency radio tag to the firearm; storing, in the data storage device of the radio tag, identification data relating to the firearm; and reading the identification data from the transceiver by interrogating the radio tag. The radio tag includes a shot sensor, a shot count register for tracking the number of shots fired and cadence registers for tracking the intervals between shots.
摘要:
A system for tracking weapon health includes a low frequency networked radio tag coupled with a firearm, said radio tag configured to receive and send data signals; a reader configured to be in operative communication with the tag antenna; and a display configured to display data relating to weapon health. The radio tag includes a shot sensor, a shot count register for tracking the number of shots fired and cadence registers for tracking the intervals between shots.
