An automatic identification system for communicating identifying information by coupling signals through the human body is provided. The system includes a battery powered identification device that transmits an identifying signal via a modulated carrier. The identification device is coupled to the body of the user via a coupling plate. The signal from the identification device is received by a reading device that is also coupled to the body of the user via a coupling plate. The reading device may display and/or enunciates the identifying information to the user. The coupling technique, carrier frequency, and construction of the devices are such that the identification information is not inadvertently radiated or coupled to unintentional users or receivers.

In the present invention, by connecting a band-gap reference voltage module unit to a threshold unit of a limiter circuit, the ON-voltage of the threshold unit can be dynamically and continuously controlled; and the output voltage value of the band-gap reference voltage module unit can be arbitrarily set as needed for operating the circuit. When a voltage of the antenna terminal is higher than the sum of this band-gap reference voltage value and the respective threshold voltage of the serial MOS transistors, the threshold unit is turned ON to switch on a grounded path, so that charge at the antenna is output to the ground; in this way, the amount of charge at the antenna terminal is reduced and the rectified DC voltage is thus reduced. When the voltage at the antenna terminal is lower than the sum of this band-gap reference voltage value and the respective threshold voltage of the serial MOS transistors, the threshold unit is turned off to switch off the grounded path. The rectifier circuit rectifies all the charges at the antenna end into DC power for powering the load circuit. In this way, the function of continuously adjust the limited voltage is achieved, so that the limited voltage value has continuity and accuracy, and the stability of the operating voltage value of the circuits is guaranteed.

A multi-layer conductor device is disclosed comprising two or more conductors used in an antenna for a more durable radio-frequency identification (RFID) tag. The conductors interconnect electrically, but are separated mechanically, so a failure in one conductor will not necessarily cause a failure in the other conductor. And, if the failure occurs at different locations on the antenna, the current path through the antenna will bridge the break.

A method, apparatus, and computer readable storage to implement a social networking game that enables players to scan QR codes (or other identifying markers) and transmit the items scanned to a server that determines the physical location of the player. Players can play a game where they attempt to find and scan as many QR codes as possible. In an embodiment, the QR codes can also be used for crowd control. People in areas that are overly populated can be incentivized to move to lower traffic areas by offering them incentives for reporting to the low traffic area.

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 card actuated automated banking machine (10) is operative to carry out financial transactions responsive to data included on user cards. The banking machine includes a user interface (15) including a display (24). The user interface includes a card reader (16) which is operative to read data on user cards which identify at least one of user and a user's financial accounts. A fascia of the machine includes a keypad (404, 438, 458) through which users input confidential data. Covers (400, 422, 430) prevent unauthorized persons from viewing confidential inputs to the keypad. Authorization signals assure that the display is operating in a manner that provides appropriate user instructions. A visual indicator is operative to indicate to a user that keypad inputs are being encrypted. Alternatively a touch screen display module (608) is operative to securely receive manual inputs and/or card data.

A card-based method for generating a dynamic password, in which the method comprises: power on a device, initialize a current running state as a first state, prompt a user to press down a mode key, the device determines an operation to be executed when the mode key is pressed down, obtain input data according to the operation on a number key pressed by the user in the case that a number key is pressed down; obtain a confirm state according to the operation on a state key pressed by the user in the case that a state key is pressed down; otherwise, execute a corresponding operation according to the current running state, the corresponding operation comprises: obtain a dynamic password according to the interaction with the card and preset process the password data and output the dynamic password. According to the invention, both internal data of the card held by the user and information input by the user take part in the generation of the dynamic password, thus, the password data is formed to protect from being manipulated so as to make the process of generating a dynamic password more secure.

A method to identify and manage recyclable materials. The method includes the steps of: (i) identifying, using a mobile device, a recyclable material based on a detected oscillation frequency of an oscillator associated with the recyclable material; (ii) communicating, using the mobile device, information about the recyclable material to a controller, the information comprising an identification of the recyclable material and a location of the recyclable material; and (iii) creating, by the controller, scheduling instructions for the identified recyclable material.

Embodiments described herein disclose a mobile device system for displaying contactless payment options to a user of a mobile device. A location of the device may be detected. The location may be transmitted to a payment services provider, and information indicating that the location corresponds to a merchant having contactless payment options may be received. In response, graphical depictions of payment options associated with a plurality of payment sources are displayed on a touch-sensitive display of the mobile device. A selection of one of the graphical depictions is received, and in response, one or more transceivers of the mobile device, such as one or more NFC transceivers, may be activated. The activation may cause the transceivers to transmit a personal account number to a point-of-sale terminal. Thus, the user is presented with contactless payment options based on a geographical location, and may be presented with a suggested payment source.

Systems and methods for integrating tags with items. The methods comprise: dynamically determining a length of each metal thread to be incorporated into or trace to be disposed on a item to optimize tag performance in view of dielectric and tuning properties of the item. In the metal thread scenarios, the methods also involve: creating a metal thread having the length that was dynamically determined; and sewing the metal thread into the item being produced to form an antenna for a first tag. In the trace scenarios, the methods also involve forming the trace on the item being produced to form an antenna for a first tag. Next, at least a communications enabled device is attached to the item so as to form an electrical coupling or connection between the communications enabled device and the at least one antenna.
