A payment terminal evaluator includes a contact structure and a card structure. The contact structure intersects a rectangular space such that part of the contact structure is within the rectangular space and part of the contact structure is outside of the rectangular space. The card structure extends from the contact structure and is positioned entirely within the rectangular space. The card structure includes a top surface, a bottom surface, a first side surface between the top surface and the bottom surface, a second side surface between the top surface and the bottom surface, a first tab defined in part by the top surface, the bottom surface and the first side surface, a second tab defined in part by the top surface, the bottom surface and the second side surface, and an opening between the first tab and the second tab.

An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other. The information reading unit generates a data string on the basis of a unit signal formed from a plurality of signals output from a group of detection units that detect the marks in synchronization and recognizes the digital code of the information bearing medium on the basis of a group of the data strings sequentially obtained from the array of the unit data zones.

An incontinence detection system monitors an area for moisture events and wirelessly transmits moisture-related information to one or more notification devices. The system has a pad that includes a substrate and one or more sensors supported by the substrate. The sensor(s) emit wireless signals indicative of the moisture-related information. A sensor event communication system forwards the sensor signals to another device, such as a notification device. Portions of the system are included in a patient support apparatus, such as a bed.

A test system is provided. The test system includes a test board provided with a near filed communication chip and including an antenna; a tag holding apparatus including first and second tag holders accommodating first and second NFC tags, respectively, and a first controller configured to adjust a position of each of the first and second tag holders; and a second controller configured to: transmit a first test signal to the test board to perform a first communication test for the NFC chip and the first NFC tag; receive a result of the first communication test; and determine whether or not the NFC chip normally reads first data stored in the first NFC tag. The first controller is configured to place the first NFC tag and the antenna to be spaced apart from each other by a first distance based on a type of the first NFC tag and face each other, and rotate the first and second tag holders when the first communication test is completed.

The present technology includes calculating the 3-D RF propagation pattern in a space for at least one Wi-Fi access point and displaying a visualization of the RF propagation pattern in augmented reality (AR). The augmented reality view of the space can be created by capturing at least one image of the space and displaying at least one image of the space on a display with the visualization of the Wi-Fi access point RF propagation pattern on the display overlaid at least one image of the space. The disclosed technology further can calculate the RF propagation properties and render a visualization of the RF propagation patterns in a 3D space by utilizing hardware on a user device. The AR display is useful in visualizing, in-person aspects of a Wi-Fi network and coverage, and can be used in troubleshooting, maintenance, and simulations of equipment variations.

An industrial vehicle comprising a tag reader, a reader module, and a diagnostic tag, wherein the diagnostic tag is coupled to the industrial truck within a read range of the tag reader. The reader module and the tag reader cooperate to identify the diagnostic tag and individual tags of a tag layout and the reader module discriminates between the individual tags of the tag layout and the diagnostic tag and the individual tags of the tag layout, correlates an identified individual tag of the tag layout with tag data, correlates an identified diagnostic tag with operation of the tag reader, and generates a missing tag signal if the diagnostic tag is not identified or the operation of the tag reader is not within specified operating parameters.

A system and method for configuring Radio Frequency Identification (RFID) read and write power levels includes an RFID module that generates RF signals, a digital step attenuator that attenuates RF signals, an antenna that transmits attenuated RF signals, and an RF shield that isolates the antenna from an RFID label supply roll. A floor read power is determined by iteratively interrogating an RFID label while decreasing the RF signal power until the label fails to respond to the interrogation. A ceiling read power is determined by iteratively interrogating the RFID label while increasing the RF signal power until multiple labels respond to the interrogation. The read power level is set between the floor read power and the ceiling read power. The write power level is determined by iteratively attempting to program the RFID module while increasing the write power from the read power level until successfully written.

A device for managing operation of an object capable of contactless communication with a reader magnetically coupled to the object includes a modulator configured to modulate an impedance of a load connected across terminals of an antenna of the object during a transmission phase during which information is transmitted from the object to the reader. The device further includes a monitor configured to carry out a monitoring phase, prior to the transmission phase. The monitoring phase includes a test modulation of the impedance of the load, a monitoring of a level of amplitude modulation of a modulated test signal present at the antenna of the object and resulting from the test modulation, and a capacitive modification of the impedance of the load if this level is lower than a threshold.

A method comprises: maintaining a database (120, 130) of access control events; dividing a portion (138) of the database into shares (140A, 140B, 140C); passing the respective shares to respective third party servers (44A, 44B, 44C); processing the shares in the respective third party servers; passing output of the processing to a further server (40) in common; and processing the output on the further server.
