TL;DR: In this paper, a module test card is formed by a test substrate and a plurality of test chips mounted on the test substrate for connecting to a tester, which are then tested under simulation of their operating conditions.
Abstract: Manufacturing of semiconductor devices is facilitated when the device chip carriers of the devices are tested, prior to population of chips thereon, by a module test card. The module test card is formed by a test substrate and a plurality of test chips mounted on the test substrate. Connections are provided on the test substrate for connecting to a tester. Through the module test card, the device chip carriers are tested under simulation of their operating conditions.

TL;DR: A plug-in JTAG test card (200) includes JTAG boundary scan circuitry (230) which may be used to drive test data out onto portions of buses (170, 195) connected to peripheral slots (160, 180, 190).
Abstract: A plug-in JTAG test card (200) includes JTAG boundary scan circuitry (230) which may be used to drive JTAG test data out onto portions of buses (170, 195) connected to peripheral slots (160, 180, 190). One or more of the JTAG plug-in test cards (200) can be used to verify the integrity of each of the point-to-point connections on the buses (170, 195) which terminate in the peripheral plug-in slots. In one advantageous embodiment, the plug-in JTAG test cards (200) simulate a dual in-line memory module (DIMM) or single in-line memory module (SIMM) cards which include scan test buffer circuitry (230) but do not actually include memory chip so that an inexpensive plug-in card (200) can be used to provide JTAG testing at the manufacturing level for multiple motherboards (600). In a particularly preferred embodiment, JTAG boundary scan buffer circuits (230), such as, for example, SN74ABT8245's, are used as test circuits rather than for their intended use as interface circuits.

TL;DR: A test card for drugs of abuse has a thin flat member having the size and shape of a business card as discussed by the authors and a plurality of immunoassay test strips extend longitudinally from top to bottom of the card and are fastened side by side in parallel on one or both sides of the test card within the outline.
Abstract: A test card for drugs of abuse has a thin flat member having the size and shape of a business card. A plurality of immunoassay test strips extend longitudinally from top to bottom of the card and are fastened side by side in parallel on one or both sides of the test card within the outline of the card. Each test strip is reactive to provide a visual indication in response to a particular drug of abuse. The test card thus provides for the simultaneous detection of multiple analytes. Processes are also disclosed for making the drug test card with test strips on one and both sides of the card.

TL;DR: A disk drive test apparatus (1) has a plurality of bays (4) each for receiving a respective disk drive to be tested as discussed by the authors, each of the test cards is either an environment test card or an interface test card.
Abstract: A disk drive test apparatus (1) has a plurality of bays (4) each for receiving a respective disk drive to be tested. A plurality of card slots (6) are provided each for receiving a test card (7, 8) via which a disk drive can be tested. Each of the test cards is either an environment test card (7) or an interface test card (8). The card slots (6) and the test cards (7, 8) are arranged such that each card slot (6) can selectively receive an environment test card (7) or an interface test card (8). Other arrangements for disk drive test apparatus or disk drive mounting apparatus are disclosed.

TL;DR: In this article, a smart card reader dedicated to a particular application and using both a microcontroller (MC) whereof the read-only memory determines the operation of the application, and a security component (CS) executing, under the microcontroller control, sub-programmes related to application security (authentication, confidential programs and the like).
Abstract: The invention concerns smart card readers dedicated to a particular application and using both a microcontroller (MC) whereof the read-only memory determines the operation of the application, and a security component (CS) executing, under the microcontroller control, sub-programmes related to the application security (authentication, confidential programmes and the like) In order that the application manager may access certain zones of the security component memory, it is provided that the microcontroller can automatically shift into a so-called 'transparent' mode, when a specific access code transmitted by the test card is recognised In this mode, the reading or writing instructions of a memory zone of the security component, transmitted by the test card, are interpreted by the microcontroller as being reading or writing instructions of a memory zone of the security component and not of the microcontroller The invention is applicable to portable readers
