Abstract: An electrical connector for use in electrically conductive aqueous mixtures, solution or suspensions such as seawater, sewage, electrolytes and so forth has one or more contact pins 3 each having a contact area 4. The contact areas 4 are electrically isolated from the electrically conductive environment by way of a dielectric seal carrier 6 which may be moved away from the contact areas 4 as the socket and the plug of the connector are brought into engagement.
Abstract: An information scanning apparatus for scanning and marking parts of a written text comprises two viewing elements (14,16) for forwarding information concerning scanned text to a linescan camera (42) so as to provide two physically displaced digital images of the relevant parts of the text. A highlighter pen (34) located adjacent the viewing elements (14,16) marks the scanned text as well as providing control feedback to the scanning operation such that the apparatus can deal with variations in speed, text quality and attitude of the scanning head 10.
