Abstract: A measurement apparatus is disclosed for connection to an end of a cable (1) having at least one of: at least one electrically conductive core (11) for carrying electrical current and/or electrical signals along the cable; at least one electromagnetic waveguide (12) for carrying electromagnetic signals along the cable; and at least one bore (13) for conveying a fluid along the cable. The measurement apparatus comprises: connection means (4) for connecting to the end in an above-water or out-of-water environment to make at least one of: at least one respective electrical connection (41) to at least one core, at least one respective waveguide connection (42) to at least one waveguide for sending an electromagnetic signal along the waveguide, and at least one respective fluid or hydraulic connection (43) to at least one bore; and measuring means (5) connected to the connection means and operable to perform at least one measurement, via the connection means, on a connected cable.

Abstract: A method for programming a microprocessor using first and memory banks, a reset circuit, and an address decode circuit. The first bank of memory contains a current program. The second bank of memory contains an updated program. The microprocessor is initially booted using the current program, and then rebooted using the updated program. During the second reboot using the updated program, the microprocessor performs diagnostics to verify that the updated program is operational and/or error free. If the updated program is operational and/or error free, the updated program is used for future initial boots. If the updated program is not operational and/or error free, the microprocessor reboots using the current program, and a fail signal is generated, so that the updated program can be replaced.

Abstract: A testing method and apparatus for testing complex board assemblies by configuring the data paths on the multiple boards into one larger virtual data path. The system uses reconfiguration commands and serial data streams to test the virtual data path, and reconfigures the virtual data path as sections are tested to shorten the virtual data path after each data stream is verified, thereby reducing test time and cost.
