A method and system for communicating estimated blood loss parameters of a patient to a user, the method comprising: receiving data representative of an image, of a fluid receiver; automatically detecting a region within the image associated with a volume of fluid received at the fluid receiver, the volume of fluid including a blood component; calculating an estimated amount of the blood component present in the volume of fluid based upon a color parameter represented in the region, and determining a bias error associated with the estimated amount of the blood component; updating an analysis of an aggregate amount of the blood component and an aggregate bias error associated with blood loss of the patient, based upon the estimated amount of the blood component and the bias error; and providing information from the analysis of the aggregate amount of the blood component and the aggregate bias error, to the user.

A wireless access method, device and system is disclosed that enables remote dynamic configuration of wireless devices which emulate wireless tags, while maintaining compatibility with prior art access systems. This enables wireless tags to be shared in a manner that allows copies of the tags to remain synchronised with each other. The system includes a remote server, configured to selectively provide tag data to the wireless devices to enable the wireless devices to emulate the one or more wireless tags using the selectively provided tag data. In use, the wireless tags are configured to first retrieve tag data from the remote server, and subsequently emulate one or more wireless tags according to the retrieved tag data.

A biological sample storage container and a dual chip wireless identification tag thereof are provided. The dual chip wireless identification tag includes a substrate, an antenna structure, a first chip, and a second chip. The antenna structure is disposed on the substrate, and includes two radiation parts and two matching parts. The two matching parts are connected between the two radiation parts, the first chip is coupled to one of the matching parts, and the second chip is coupled to the other one of the matching parts.

A universal radio frequency identification reader and emulation handheld device and system configured to read and emulate radio frequency identification tags in the low frequency, high frequency, and ultra-high frequency spectrums. The system may include a mobile or a web application to control and interact with the handheld device. The mobile application may receive an identifier of an RFID tag, upload the identifier to a server, determine, via the server a chip/identifying number of the RFID, and command an RFID emulator to emulate an RFID tag based on the received chip/identifying number.

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable of communicating information to a magnetic stripe reader. Information used in validating a financial transaction is encrypted based on time such that a validating server requires receipt of the appropriate encrypted information for a period of time to validate a transaction for that period of time. Such dynamic information may be communicated using such an emulator such that a card may be swiped through a magnetic stripe reader—yet communicate different information based on time. An emulator may receive information as well as communicate information to a variety of receivers (e.g., an RFID receiver).

A high speed tabletop and industrial printer is disclosed with integrated high speed RFID encoding and verification at the same time. The industrial printer simultaneously prints on and electronically encodes/verifies RFID labels, tags, and/or stickers attached to a continuous web. The industrial printer comprises a lighted sensor array for indexing the printing to the RFID tags; and a cutter powered from the industrial printer for cutting the web that the RFID tags are disposed on. The industrial printer comprises two RFID reader/writers that are individually controlled. Specifically, one of the RFID reader/writers comprises the ability to electronically encode the RFID tags while the web is moving; and the second RFID reader/writer uses an additional RFID module and antenna on the printer for verifying the data encoded to the RFID tags. The printer provides for successive writes to various memory blocks and optimizes the communication sequence between the interrogator and tag.

A universal radio frequency identification reader and emulation handheld device and system configured to read and emulate radio frequency identification tags in the low frequency, high frequency, and ultra-high frequency spectrums (from 30 kHz to 1050 MHz). The system may include a mobile or a web application to control and interact with the handheld device. The system may allow for the saving of radio frequency identification tag information in cloud infrastructure for later emulation.

A method for vehicle-loading warehousing asset management based on an ultra-high frequency (UHF) radio frequency identification (RFID) path loss model, which includes the following steps. An electromagnetic wave is emitted by a tag reader. The electromagnetic wave is diffracted, reflected, and scattered when passing through a warehousing vehicle hood, and the electromagnetic wave is emitted and scattered through the ground. A UHF RFID tag attached to a front surface location region of assets receives electromagnetic waves of various paths emitted by the tag reader. The tag reader reads UHF RFID tag information. A transfer function of a tag receiving signal is constructed according to the tag information, and a path loss function during a UHF RFID tag sensing electromagnetic wave process is constructed according to the transfer function. The path loss is calculated according to the constructed path loss function. A location of the UHF RFID tag is obtained.

A magnetic field induction coupled RFID system for scanning and reading at least one object having an RFID tag or inlay label device attached or embedded therein to impart a unique identity to each of the objects. The RFID tag has two distinct modes of air interface protocols operating in the same frequency band (e.g., HF band), such that the tag is capable of being read at close proximity range by a device utilizing a command-and-control protocol, such as an NFC-protocol compatible smartphone or similarly functioning device, and alternatively by an RFID reader utilizing a different protocol capable of supporting efficient high-speed anti-collision features for enabling fast inventorying at item level of retail store items, warehousing, customs and logistics operations over considerably greater interrogation distances. The passive RFID can further include a third mode of air interface protocol operating in a different (second), e.g., UHF, frequency band, such as EPCGlobal Class-1 Generation-2 conforming protocol, or a commandless asynchronous protocol operating at UHF.
