Abstract: The thoracic catheter has an elongated, integrally formed lead designed to be pulled by the surgeon without the use of a clamp. The lead has sufficient length to allow it to be readily held within the surgeon's hand, or even wrapped around the hand. A tip at the proximal end of the lead is used to guide the lead through the chest wall. In the alternative, the tip may have a trocar that is used to make the secondary incision in the chest wall for the placement of the catheter.

Abstract: A multihardness foamed seat having side rolls including one or more zones of a second polyurethane foam encapsulated in a first polyurethane foam is prepared by arranging the seat mould (10) so that the side roll well (12) is inclined in a direction parallel to its length, introducing a liquid first foam formulation into the side roll well, and then introducing a liquid second foam formulation within a time interval corresponding to between 0.01t to 1.5t where t is the cream time of the first foam formulation. The process is particularly useful for the preparation of automobile seats having side rolls.

Abstract: Automotive vehicle test equipment includes a controller which controls power supplied to a test circuit. The controller monitors a sleep mode switch which determines whether the controller enters a sleep mode. In sleep mode, the controller disconnects the test circuit from a power source. The controller also monitors a telephone line. Upon detection of a ring signal on the telephone line, the controller connects the test circuit to the power supply.

Abstract: The air/fuel ratio of the combustion mixture in the cylinders of an engine is sensed and the sensed air/fuel ratio is controlled to a predetermined scheduled air/fuel ratio by controlling the amount of exhaust gases recirculated. When the exhaust gas recirculated is substantially zero, the air/fuel ratio is thereafter closed loop adjusted to a predetermined scheduled minimum air/fuel ratio when the sensed air/fuel ratio is less than the minimum and when the sensed air/fuel ratio is greater than the minimum while the operator command is at a maximum to thereby provide precise fuel limiting at a predetermined fuel limit schedule.

Abstract: An anti-tamper device in an automotive vehicle test system monitors an access panel to the automotive vehicle test system. An alarm is actuated if the access panel is opened. The automotive vehicle test system tests automotive vehicles and prints certificates which verify test results. The access panel is unlocked following the completion of an automotive vehicle test so that an operator can gain access to a printer to retrieve a printed certificate. The test system monitors the condition of the access panel even if power is removed from the automotive vehicle test system. A large capacitor provides power to monitoring circuitry. A data latch, powered by the capacitor, latches the condition of the access panel. The alarm is sounded when power is returned to the automotive vehicle test system and the condition of the latch indicates that an access panel has been opened.
