A passive entry system for an vehicle door requires no active operator input to gain entrance to the vehicle. A door module recognizes the signal transmitted by an authorized key fob to identify the operator of the vehicle. The authentication of the operator coupled with the operator touching a sensor on the door to be opened actuates a release actuator that unlatches the selected door. The spring-load provided by the door seal will pop the door open from the closed position. A key cylinder, which can be located substantially anywhere on the door, is coupled mechanically to the release latch for use if the battery is weak and cannot activate the release actuator. An LED signals the state of the opening sequence for the door. The fixed door handle can incorporate a membrane switch or a capacitive sensor to indicate the selection of the door by the operator when touched.

A lancing assembly is pivotally coupled to a housing and includes an actuator and a leaf spring carrying a lancet. When the actuator is in its set position, the leaf spring and lancet are in their set position with the leaf spring engaging a catch member of the housing. When the actuator is moved to its actuated position, the leaf spring pivots and deflects against the catch member, thereby storing a drive charge. The leaf spring then releases from the catch member as the stored charge launches the lancet to its lancing position. The leaf spring recharges towards the end of the lancing stroke, which return charge then retracts the lancet back into the housing.

Barrier elements couple together into a longitudinal wall to provide security from terrorist threats by being able to withstand both vehicle collisions and explosive blasts. Each barrier element is prefabricated to include a massive block of durable material, preferably high strength concrete, cast about one or more beams that are preferably made of steel and extend longitudinally through the block. Multiple blocks are positionable on top of the ground with their beams coupled longitudinally to one another, end-to-end.

A plasma arc torch has a threadless electrode-cathode locking assembly, a one-piece tip assembly, and a rotational contact starting mechanism. The cathode and electrode of the locking assembly are configured such that relative rotation of the electrode with respect to the cathode causes the electrode to move in an axial direction relative to the cathode for locking the electrode in fixed axial and rotational position with respect to the cathode. The inner wall of the one-piece tip assembly is configured to receive the forward end of the electrode in a non-contact position. Rotation of the electrode with respect to the tip causes an arcing formation on the electrode to contact an arcing chamber within the cavity. Rotation of the electrode away from the tip generatesa pilot arc in the arcing chamber.
