Methods and systems related to near field communication (NFC) front ends for point of sale terminals are disclosed. One point of sale system includes an applications microprocessor programmed to: (i) instantiate an operating system for the point of sale system and (ii) generate a set of data packets. The system also includes a discrete microcontroller communicatively coupled with the applications microprocessor and programmed to: (i) selectively operate in an unsecure mode and a secure mode; and (ii) filter, when operating in the unsecure mode, the set of data packets received from the applications microprocessor using a filter and a whitelist for the filter. The system also includes a near field communication front end communicatively coupled to the discrete microcontroller and an antenna, for transmitting a near field communication signal based on information from the set of data packets via the antenna.

Systems and methods involving secure connections between security meshes are disclosed herein. One disclosed device includes a first security processor located within a first security mesh, a first casing having a connector and supporting the first security mesh and the applications processor, a second security processor located within a second security mesh, and a second casing connected to the first casing via the connector and supporting the second security mesh. The first security processor and second security processor are programmed to generate a unique pre-shared key independently on both the first security processor and the second security processor using an elliptic key exchange and establish a secure connection between the first security processor and the second security processor using the unique pre-shared key.

Embodiments of the present invention enable near field communication (NFC) through a touch display. Some embodiments include specialized touch displays with lower electromagnetic dissipation factors than standard touch displays. Some embodiments include methods and devices for detecting the activation or deactivation of NFC communication using the touch display and adapting the touch display to that activation or deactivation. Disclosed techniques for adapting the touch display include optimizing the behavior of the touch display for operation in the face of electromagnetic interference when NFC is activated and conducting a partial recalibration of the touch display when NFC is deactivated.

Providing near field communication through a touch screen

Methods and systems related to near field communication (NFC) front ends for point of sale terminals are disclosed. One point of sale system includes an NFC front end communicatively coupled to an antenna, a discrete microcontroller (DM) communicatively coupled thereto, and an applications microprocessor (AP) communicatively coupled to the DM. The DM stores a first software stack for a first NFC protocol, a second software stack for a second NFC protocol, and instructions to process a digitized NFC signal from the NFC front end with the first software stack. The AP stores instructions to instantiate an operating system for the point of sale system, instantiate a master NFC service, and transmit a remote procedure call from the master NFC service to the DM to switch between the first software stack and the second software stack.

We describe an architecture for a large-area, touch-sensitive electronic document reading device which is able to tolerate bending. In broad terms, a control circuit board is mounted behind a flexible display structure in the housing and at respective points of attachment of first and second laminar connectors to the control circuit board each laminar connector has a plurality of electrical connections running along a longitudinal direction of the laminar connector and disposed alongside one another in a transverse direction across the laminar connector. At the respective points of attachment of the first and second laminar connectors to the control circuit board the longitudinal directions of the laminar connectors are aligned such that, when said device is flexed, a relative displacement in said longitudinal direction between said control circuit board and of said display structure can be tolerated without damage to the control electronics, touch sensitive display screen or connections therebetween.

A fluidic medical diagnostic device permits measurement of analyte concentration or a property of a biological fluid, particularly the coagulation time of blood. The device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. A channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. The desired measurement can be made by placing the device into a meter which measures a physical property of the sample&#x2014;typically, optical transmittance&#x2014;after it has interacted with a reagent in the measurement area.
