By virtue of its composite mechanical nature, the so-built inertial meta-material gains enhanced capacities of passive frequency-band filtering.
Because the transponders have to be carried by insects in flight, extreme miniaturisation was obviously essential and it was achieved by using a passive, frequency-doubling technique, so that no on-board battery was needed.
It has been shown earlier by the present authors that every passive future frequency domain behavior ˆW+ on W may be realized as the future frequency domain behavior of some passive s/s system Σ, and that it is possible to require, in addition, that Σ is (a) controllable and forward conservative, (b) observable and backward conservative, or (c) simple and conservative.
In this paper, we will consider only passive ultrahigh frequency (UHF) RFID systems.
A robust passive high frequency high pressure micro check valve was developed for piezoelectrically actuated pumps.
Passive radio frequency identification (RFID) is increasingly being used to identify and trace objects in supply chains, in manufacturing process, and so forth.
This paper takes a passive radio frequency identification (RFID) tag-based locating and navigating approach for AGV to examine the influences of tags, antennas, and environmental aspects.
The scope of this research is the use of passive radio frequency identification (RFID) as the sensing technology and focuses on the operation and maintenance phase of the lifecycle of an office building.
Passive Radio Frequency Identification (RFID) tags, due to their ability to uniquely identify every individual item and low cost, are well suited for supply chain management and are expected to replace barcodes in the near future.
In this paper, we present the received signal strength of passive radio frequency identification (RFID) tags that can be used to carry out on-site shopping data mining, such as which items are popular, which goods are customers interested in, which items are usually bought together, which areas have a large customer flow, and what is the order of items being bought by customers.
