摘要:
A tag holder includes a top surface, a bottom surface opposite to the top surface, an inner surface, and an outer surface. The outer surface and the inner surface connect to the top surface and the bottom surface. The top surface defines at least one receiving cavity. The inner surface defines at least one groove. RFID tags are held by the tag holder in such a way as to provide ease of reading the tags, and to reduce any electromagnetic interference offered by the object to which the tag holder is attached.

A detection unit positioned on a package includes a magnet, a first magnetic switch, a second magnetic switch, a processor, and a clock. The first magnetic switch outputs a first control signal or a second control signal according to magnetic flux density of the magnet. The second magnetic switch outputs a third control signal or a fourth control signal according to the magnetic flux density of the magnet. The first control signal is the same as the third control signal; the second control signal is the same as the fourth control signal. When the processor receives the first control signal and the third control signal at the same time, the processor reads a first real-time clock (RTC) signal from the clock. When the processor receives the second control signal and the fourth control signal at the same time, the processor reads a second RTC signal from the clock.

A monitoring system for a parking space includes a number of radio frequency identification (RFID) tags, a monitor, a data transceiver, and a data center. The monitor corresponds to one of the parking spaces and is positioned in the parking space. When the monitor identifies an RFID tag within the parking space, the monitor records an occupied state of the parking space. When the monitor identifies the RFID tag is no longer within the parking space, the monitor records a vacant state of the parking space. The data center communicates with the monitors using the data transceiver, and stores the vacant state and/or the occupied state of the parking space.

A radio frequency identification (RFID) reader includes a main body, a first connecting portion, and a second connecting portion. The first connecting portion and the second connecting portion are positioned at two sides of the main body. The first connecting portion is configured to connect to the second connecting portion of another RFID reader and interconnecting the RFID reader to another RFID reader in series.

A control unit for tracking articles is positioned approximate to a package and communicates with a reader. The control unit includes a radio frequency identification (RFID) tag, a switch, a clock; and a microcontroller. The switch outputs a first control signal to the microcontroller when the package is opened. The microcontroller reads a real-time clock (RTC) signal from the clock according to the first control signal, and transmits an open status signal and the corresponding RTC signal to the RFID tag. The RFID tag feeds back the open status signal and the corresponding RTC signal to an RFID reader.
摘要:
A fixed reader in communication with a portable reader includes an induction circuit and a microcontroller. The induction circuit receives wireless signals sent by the portable reader, and outputs control signals according to the received wireless signals. The microcontroller is electronically connected to the induction circuit, and activates the fixed reader according to the control signals, to allow the fixed reader to enter into a working state or an idle state.
摘要:
An anti-counterfeiting article includes a first part, a second part, a first radio frequency identification (RFID) tag, and a second RFID tag. The second part of the article is detachably attached to the first part. The first RFID tag is attached to the first part, and the second RFID tag is attached to the second part. The first RFID tag pre-stores a first identification code, the second RFID pre-stores a second identification code, the first identification code is identical with or is related to the second identification code in a some way or according to a predetermined criteria for confirming the status of the article as a certified product.
摘要:
A method for directing display of a standard operation procedure of an item using multimedia devices positioned on at least one workbench that produces the item. The method divides the SOP into several instruction steps, assigns a corresponding identifier to each instruction step of the SOP, and sends a start command to multimedia devices. The method further downloads and directs a instruction step of the SOP having the same identifier with the multimedia device if the multimedia device receives the start command.
