Abstract: Eine Sicherheits-Kontaktiervorrichtung zum Erkennen von zwei zueinander gehörenden Kabeln einer Solarzellenreihenschaltung, umfasst mindestens eine erste Messelektrode (7a, 7b) mit einer Spitze zum Anlegen an den Kern (6) eines ersten Kabels. Um zwei Kabel, zwischen denen eine Gleichspannung herrscht, problemlos aus einer Vielzahl von Kabeln eines Kabelbündels zu ermitteln, weist die Sicherheit-Kontaktiervorrichtung einen Grundkörper (10, 10a) mit einer Kabelaufnahme (11, 11a, 11b, 11c) zum Einführen und Halten mindestens eines der Kabel auf, wobei die Messelektrode (7a, 7b) innerhalb des Grundkörpers (10, 10a) durch Führungsmittel geführt und in Richtung der Kabelaufnahme (11, 11a, 11b, 11c) und/ oder des Kabels verbringbar ist. Die Kabelaufnahme (11, 11a, 11b, 11c) ist koaxial zur Bewegungsachse durch die Messelektrode (7a, 7b) angeordnet, so dass die Spitze der Messelektrode stets den metallischen Kern (6) des ersten Kabels trifft.

Abstract: A method of testing an aircraft landing gear. The landing gear comprises first and second wheels; a first braking system comprising a first tachometer mounted to the first wheel and configured to generate a first tachometer signal indicating rotation of the first wheel, and a first brake configured to brake the first wheel; a second braking system comprising a second tachometer mounted to the second wheel and configured to generate a second tachometer signal indicating rotation of the second wheel, and a second brake configured to brake the second wheel; first and second tachometer output lines; a first braking command line associated with the first tachometer output line; and a second braking command line associated with the second tachometer output line. The method comprises: a) generating a test signal with the first tachometer, wherein the first wheel is not rotating during the generation of the test signal; b) receiving the test signal via one of the tachometer output lines; c) issuing a braking command in response to the receipt of the test signal, wherein the braking command is issued via the braking command line which is associated with the one of the tachometer output lines; and d) monitoring a response of the first or second braking system to the braking command to test for a cross-connection between the first and second braking systems.

Abstract: A permanently installed absence of voltage tester (AVT) may include a connectivity verification system for verifying the connectivity of system cable leads to the main power lines in electrical equipment. An installed AVT may indicate whether the electrical equipment is in an electrically safe state without first requiring direct access to the equipment. One step in the AVT test procedure may include connectivity verification by the connectivity verification system, which may include a sub-procedure to confirm that the installed AVT is directly coupled as intended with direct connection to the equipment being monitored. The connectivity verification system may validate that the AVT is measuring the actual voltage on the power lines of the electrical equipment and has not registered a no-voltage condition due to an unknown disconnection error or installation failure.
