摘要:
Methods of coding and retrieving information by using the unique emission properties of the semiconductor nanocrystals (quantum dots) for the identification of valuable documents, articles and objects are described. A carrier medium is prepared containing quantum dots selected to give the carrier medium defined fluorescent emission characteristics encoding predetermined information. The carrier medium is then applied to the object, preferably in the form of an ink.

Disclosed herein is a portable communication device. The portable communication device includes a first housing extending in a first direction, a second housing extending in a second direction perpendicular to the first direction and formed at a bottom surface of the first housing so that a predetermined region of an outer circumferential surface of the second housing protrudes perpendicularly outward from the bottom surface of the first housing, and a camera lens module rotatably or linearly movably mounted in the second housing. The camera lens module is inserted into or drawn out from the second housing in the second direction. The camera lens module is repeatedly inserted into and drawn out from the second housing by pushing the camera lens module, and the camera lens module moves upward and downward when it is drawn out from the second housing.

A printing unit 14 is built into an upper portion of a handheld terminal (11), a display unit (13) is built into the middle portion, and a key inputting unit (12) is built into a lower portion. A laser type scanner (15) for reading a barcode, etc. is built into the right side of the main body, and a switch (16) for turning on/off the scanner (15) is built into the proximity of the bottom of the scanner (15). The scanner (15) is aimed at the direction of a barcode, and the switch (16) is turned on to irradiate a laser beam, so that the barcode can be read.

A system is described for managing data and information in a healthcare environment, such as a hospital. A handheld code scanner reads codes and either accepts data, or performs instructions based on the read code. The code scanner wirelessly transmits the codes or data to a central server which acts on the read code to carry out necessary functions. The system is useful for tracking patient data, such as for delivery of medicine. In addition, since the system can carry out instructions, it is useful for allowing healthcare workers to quickly and conveniently perform their duties without the necessity of sitting at a computer terminal.

A scanning device adapted to scan an interface surface provided on a product item, the interface surface having disposed thereon coded data indicative of an identity of the product item, the product item being provided in a sensing region, the scanning device including: a beam generator for emitting at least one beam; first and second acousto-optic deflectors for deflecting the beam in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch; a sensor for sensing at least some of the coded data on the interface surface of the product item as the product item passes through the sensing region; and a processor for determining, using at least some of the sensed coded data, product identity data indicative of the identity of the product item.
摘要:
In a non-contacting smart card interrogator (1) a first end (A) of an eighth-wave transmission line (13) is connected to a terminal connecting a first receiver (16) to a transmission line (14), and to a second end (B) of the transmission line (14) the carrier wave generator (11) is connected. To the first end (A) of the eighth-wave transmission line (13) the first amplitude demodulation receiver (16) and to the second end (B) thereof a second amplitude demodulation receiver (16null) are connected. In the non-contacting smart card interrogator of the invention an effective use of amplitude demodulation is made possible by changing the phase modulation into an amplitude one by means of a passive element, whereby, however, no noise source has been introduced into the system.
