Abstract: An adapter cable designed to power the CHATS computer system in a military vehicle by utilizing a 24-volt DC power outlet to provide power to the computer system's internal transformer, allowing the vehicle's generator to recharge the computer's battery as well as operate the computer and all associated components. The adapter cable's ten (10) foot length added to the CHATS power cable's length of approximately five (5) feet allows the user to operate the CHATS computer system in a remote location up to 15 feet from the vehicle while still relying on the vehicle's electrical system for power. This eliminates the need for a portable generator and greatly extends the time that the computer system can be operated in remote locations. This time limit is governed only by the amount of fuel required to operate the supporting vehicle for half an hour every five hours.

Abstract: A geophysical connector features a combination of male and female connectors in a single plastic injection molded part. The single injection molding process allows two connectors to be manufactured simultaneously, rather than separately. The design provides higher efficiency in the manufacturing process, and lowers the cost of a traditional male/female connector subassembly, resulting in fewer rejects and a more consistent quality product. The durability of the product connector is increased as a continuous wiring circuit is created which is uninterrupted between lead line and the connectors, as opposed to splicing one connector into the lead line to a geophone.
