A test apparatus adapted for testing different electronic devices is provided. The apparatus provides a standard interface for operating with the different electronic devices. The interface provides an optional interface region, an optional test command region, and a selected test command region. The optional interface region is for displaying optional interfaces. The optional test command region is for displaying optional test commands relating to an interface selected in the optional interface...

The present invention provides a test apparatus comprising: a threshold voltage setting unit for setting threshold voltages of a logic device component connected to the signal propagation path; a test signal supply unit for supplying a test signal to the test subject device so as to operate the logic device component provided to the signal propagation path in a state in which the threshold voltages have been set to first threshold voltages, and in a state in which the threshold voltages have bee...

A test plug for sealing an internal passageway of a vessel preparatory to pressure testing the vessel with a fluid. The test plug is particularly designed for use with vessels that are installed below ground level, and is of the type that can be actuated from ground level to provide the desired sealing function. When the plug is intended to seal an internally threaded passageway of the vessel, it includes an externally threaded seal plate that is rotated into threaded engagement with the interna...

A simple, sensitive, reliable and safe method and device for detecting a polypeptide or glycoprotein antigen. The test involves concentration in the presence of polyvinylpyrrolidone by ultrafiltration of a sample of urine or serum from a subject; followed by determining the presence of said polypeptide or glycoprotein antigen or a particular subunit thereof in the concentrated sample.

A portable test set is disclosed for rapid pair identification, polarity determination, and half-tap verification in conjunction with modular testing apparatus employed in splicing cables--particularly cables used in the telephone industry for interconnecting telephone switching systems and subscriber equipment. Switchable meters operating in combination as a single indicator are provided for determining individual line pair conditions prior to execution of simultaneous multiple pair splicing op...

A test indicator comprising a holder to which is pivoted a measuring arm with a measuring tip; a casing equipped with a means for magnifying the displacement of said measuring tip; and an intermediate shaft which moves axially in response to pivoted displacement of the measuring tip, thereby transmitting pivotal displacement of the tip to the magnifying means, the holder being fitted to the casing for 360.degree. rotation around the intermediate shaft so that the plane of pivotal movement of the...

A test stand including a coupling for coupling a dynamometer to a drive sprocket of a vehicle to be tested and including a housing adapted to be rotated about an axis and having elongated guides in a plane generally transverse to the axis, at least two slides movably received in the guides, a screw shaft journalled for rotation in the housing and connected to the slides, the screw shaft being fixed against substantial longitudinal movement within the housing and, when rotated, effecting simultan...

A thrombosis test is based on the presence of specific, newly-found, enzyme-inhibitor complexes (such as plasmin-antiplasmin, plasmin-.alpha..sub.2 -macroglobulin, thrombin-antithrombin-III) in blood samples having an activated blood coagulation and/or fibrinolytic system. The test is immunochemical and uses a purified antiserum which has been generated against the enzyme-inhibitor complex. The antiserum is purified by incubating the antiserum with plasminogen and fresh blood plasma and isolatin...

An apparatus for making electrical contact with plural test points on one of two oppositely facing sides of a planar test member. A test member support has a test member test location. A door is provided for opening and closing access to the test location. The door and support form, when the door is closed, a substantially closed cavity therebetween encompassing the test location. The door and the support each comprise one of two opposing walls of the cavity. An array of relatively spaced electr...

There is provided a test apparatus for testing a memory-under-test for storing data strings to which an error correcting code has been added, having a logical comparator for comparing each data contained in the data string read out of the memory-under-test with an expected value generated in advance, a data error counting section for counting a number of data inconsistent with the expected value, a plurality of registers, provided corresponding to each of a plurality of classes, for storing an u...
