Reference equipment including a reference card and a reference reader is provided for testing electronic payment devices such as cards and card readers. The reference equipment is designed to simulate the external behavior of a variety of payment devices that are currently or expected to be deployed in electronic payment systems. Further, the reference equipment is configured to subject devices under test to extreme behaviors which are expected in field use or which are representative of a large class of payment devices. The external behaviors may relate to functional parameters, for example, power consumption, resonance frequency, Q-factor, modulation depth, noise, and timing. Exemplary reference devices are configured to exhibit representative external behavior, which is an empirically determined average behavior of the product devices in the field. Use of the reference equipment for product specification compliance testing will enhance the interoperability of product payment devices.

An offset tape measuring tool marked with standard English measurements includes integrated indicia for quick determination of distance between bends for a given offset depth and offset angle when installing conduit. Additional indicia may be included for the measurement of the shrinkage of the conduit with respect to the specified offset depths and angles. The integrated invention may be part of a standard tape measure strip to provide a convenient multi-purpose tool. Although the tool eliminates any external calculations or table reference typically necessary when bending conduit to clear an obstacle, it still provides an optional reference card for unique bends.

A reagent is provided for the detection of an exotoxin protein produced by a beta-hemolytic streptococcus bacteria suspected of being present in a host biological fluid collected from a subject. An enzyme inhibitor is present to inhibit rogue protein modification of the substrate to prevent a false positive result of the color change. A kit is provided that is readily usable by an untrained user and merely requires that an element of the kit be contacted with a biological sample and thereafter no further actions are required by the user before a discernable color change is observed with visible or UV light and a positive / negative results reference card.

The present invention puts forward a reference card for calibrating receiving sensitivity of non-contact reading-writing tools. One key performance index of a non-contact reading-writing tool is the sensitivity of receiving response signals sent by a non-contact card. As the modulation depth curve of the applicable non-contact card is determined, the non-contact card cannot be used for the sensitivity calibration of the reading-writing tool. The reference card of the present invention can change the magnitude of modulation load at different magnetic field intensities through a switch, so as to send modulation signals at different modulation depths to the non-contact tool. The present invention can be very conveniently used to calibrate the receiving sensitivity of the non-contact reading-writing tools.

A system for measuring the diameter of a human hair (50), the system comprising: a mobile device (20); and a reference card (10) including a hair attachment mechanism (11a, 11b); the mobile device configured to convert an image of a human hair attached to the reference card by the attachment mechanism into a measurement of the diameter of the human hair, using the size of the reference card itself and / or the size of a calibration marker (12) on a surface of the reference card as a size reference.

A method of determining a time to replace a developing solution in a printer includes providing a reference card including sample patches of standard colors for predetermined colors of the developing solutions, sample patches of test colors into which the standard colors change due to contamination, and standard color differences DELTAE* calculated from standard color values Es* corresponding to the respective standard colors and measured standard contamination values Ec* corresponding to the respective test colors; inputting information about test patches for the predetermined colors into the printer and printing the test patches; and comparing the sample patches with the test patches to determine whether to replace the developing solutions. Since the reference card is provided together with a printer including information about test patches, a user can easily determine a time to replace a developing solution.

A method of measuring indications of hair type of a user, the method comprising the steps of: providing a mobile device; providing a reference card, the reference card including one or more reference markers; providing one or more of the user's hairs at the surface of the reference card; acquiring one or more images of said one or more hairs using the mobile device; identifying the path of each of the one or more hairs along the reference card; and calculating the diameter of each hair from the acquired image.

In order to present in a systemwith a distal server displaying a virtual color image in the form of an image file comprising individual color values on its website, andwith a proximal computer connected to the server and comprising a display unit (D), said computer displaying on its display unit (D) the virtual color image of the server by means of an application program,products on the display unit (D) in the most optimum colors possible, the following is proposed:[a] a reference card (K) is held in front of the computer, said reference card (K) comprising several differently colored translucent reference areas (T1, T2, T3) besides a transparent or translucent area or an opening (G),[b.1] the application program then starts a routine on the server and / or on the computer, said routine firstly outputting a first shade, for example cyan, with a first of the color values, said first shade being complementary to the color, for example red, of one (T1) of the translucent reference areas (T1, T2, T3) of the reference card (K),[b.2] the reference card (K) having that translucent reference area (T1) whose color is complementary to the first shade displayed on the display unit (D) is then held in front of said first shade, and an identifier is determined and stored for that (T1) of the translucent reference areas (T1, T2, T3) for which the shade of grey resulting from color mixture of the first shade and the translucent reference area (T1) comes closest to a shade of grey displayed on the display unit (D) and falling through the area or the opening (G),[c] the step [b.1] and the step [b.2] are repeated at least once to output a second shade, for example magenta, of a second of the color values, said second shade being complementary to the color, for example green, of another (T2) of the translucent reference areas (T1, T2, T3) of the reference card (K), and to determine and store the identifier of said other (T2) of the translucent reference areas (T1, T2, T3),[d] the identifiers of the reference areas (T1, T2, T3) determined in the preceding steps [b.1], [b.2],[c] and stored on the server and / or on the computer are input in this order into a color correction program started on the server and / or on the computer, and[e] for each image file sent by the server the color correction program is used to adjust the virtual color image for each color value included in the image file by applying the identifiers used as correction values whereby said virtual color image is displayed in colors optimized in respect of its recording conditions.
