An electrosurgical probe (10) comprises a shaft (13) having an electrode array (58) at its distal end and a connector (19) at its proximal end for coupling the electrode array to a high frequency power supply (28). The shaft includes a return electrode (56) recessed from its distal end and enclosed within an insulating jacket (18). The return electrode defines an inner passage (83) electrically connected to both the return electrode and the electrode array for passage of an electrically conducting liquid (50). By applying high frequency voltage to the electrode array and the return electrode, the electrically conducting liquid generates a current flow path between the return electrode and the electrode array so that target tissue may be cut or ablated. The probe is particularly useful in dry environments, such as the mouth or abdominal cavity, because the electrically conducting liquid provides the necessary return current path between the active and return electrodes.

A usage based pattern authenticator for monitoring and reporting on user usage patterns in an operating system using a set of security rules and user usage patterns. This computer system security tool authenticates users at the operating system level in multi-user operating systems. It supports system administrators in limiting the ability of unauthorized users to disrupt system operations using a neural network and set of rules to track usage patterns and flag suspicious activity on the system. The data collection mode collects and stores usage patterns of authenticated users. The training mode trains an artificial neural network and sets the interconnection weights of the network. The production mode monitors and reports on usage patterns, and optionally performs automatic responses when confronted with non-authenticated users.

Disclosed are embodiments a technique for inducing strain into the polysilicon gate of a non-planar FET (e.g., a finFET or trigate FET) in order to impart a similar strain on the FET channel region, while simultaneously protecting the source / drain regions of the semiconductor fin. Specifically, a protective cap layer is formed above the source / drain regions of the fin in order to protect those regions during a subsequent amporphization ion implantation process. The fin is further protected, during this implantation process, because the ion beam is directed towards the gate in a plane that is parallel to the fin and tilted from the vertical axis. Thus, amorphization of the fin and damage to the fin are limited. Following the implantation process and the formation of a straining layer, a recrystallization anneal is performed so that the strain of the straining layer is ‘memorized’ in the polysilicon gate.

A driving mechanism controller and a driving mechanism control method reduce damage to members caused by a collision. A command producing unit produces, upon the perception of the collision of a hand with an obstacle, a reversing signal for reversing a moving direction in which the hand is being moved by a motor and a position maintaining command requesting maintaining the hand at a position with respect to a direction perpendicular to the moving direction to which the hand has been displaced by the collision. After the detection of the collision of the hand with the obstacle, the hand is retracted maintaining the hand at the position to which the hand has been dislocated by the collision to separate the hand from the obstacle. Thus a pushing force exerted by the hand on the obstacle in the direction perpendicular to the moving direction is suppressed while the hand is separated from the obstacle.

Thermal degradation of a low-k organic dielectric material is avoided or limited in the proximity of a heat source such as a fusible element by overlaying the low-k material with a thermally conductive material and providing a low thermal resistance path from the thermally conductive material, possibly having a low modulus of elasticity, to a heat sink. The thermally conductive material thus provides crack-stop protection for further layers of an integrated circuit or interconnect structure above the fusible element by mechanical, chemical and thermal encapsulation of the heat source and low-k material.
