Abstract: A device for monitoring an underground utility vault environment includes environmental sensors including at least one primary sensor and at least one secondary sensor, a processor for receiving output data from the sensors and for compiling an alarm data packet, and a communications module for transmitting data from the device. The processor determines whether an alarm condition is present based on the output data from the primary sensor(s) and, when an alarm condition is present, compiles an alarm data packet comprising data derived from the primary sensor(s) and secondary sensor(s), and causes the communications module to transmit the alarm data packet. The primary sensor(s) may include a carbon monoxide sensor. The device may include a waterproof housing, a plurality of internal sensors including a gas sensor, and a port for allowing gas exchange between the environment outside the housing and the gas sensor and preventing water ingress.

Abstract: A digitized image of a map is stored in a data memory. At least one point of the image of the map is selected as reference point. Space coordinates of the location which corresponds to the reference point are determined and allocated to the reference point. A supplementary calibration information item which enables the image of the map to be calibrated in space coordinates is determined. A mobile radio telephone has a navigation device which is set up for carrying out the method.

Abstract: A feedthrough arrangement includes a titanium alloy terminal for conducting electrical current between a first environment within a housing and a second environment outside of the housing. An insulating member is positioned around a portion of the terminal. A sleeve member is positioned around the insulating member. The terminal, insulating member, and insulating member all being in sealing engagement therewith to environmentally isolate the first and second environments.

Abstract: An electrode composition that includes an electrode material consisting essentially of at least one electrochemically inactive elemental metal and at least one electrochemically active elemental metal in the form of an amorphous mixture at ambient temperature. The mixture remains amorphous when the electrode composition is incorporated into a lithium battery and cycled through at least one full charge-discharge cycle at ambient temperature.
