Abstract: Bone screw (10a) having a hollow, tubular shaft (12a) consisting of metal, such as titanium, the shaft having a head (14a) at one end and a self-tapping external thread (18a) at the other end. The head (14a) has a hexagonal recess (16a) for inserting a turning tool. An electrically insulated metallic end-piece (20a) which tapers in the direction of the end in the form of a cone or pointed arch, is inserted the other end of the shaft (12a). A receiving coil (30a) is located in the hollow shaft (12a), the terminals (36a, 38a) of the coil being electrically coupled to the shaft (12a) and to the end-piece (20a). The space between the end-piece (20a) and the end of the shaft (12a) as well as the interior of the shaft (12a) are filled with a biocompatible insulating compound (26a), such as an epoxy resin. A low-frequency electric voltage can be induced in the receiving coil by an external primary coil which is coupled to an oscillation generator. The electric voltage generates a growth-promoting current in the surrounding tissue, the shaft and the end-piece acting as tissue electrodes (stimulation method according to Kraus and Lechner).

Title: IC engine monitoring method
Inventor: HILD OLIVER
IPC: F02D41/14
Filed: 1999-09-30
Granted: 2001-01-04
Abstract: The engine is driven either by stoicheiometric or lean fuel-air mix. In lean operation, a plausibility test of the current state of the fuel-air mixture is performed. In the event of implausibility, the engine is changed over to stoicheiometric operation. During stoicheiometric operation, a torque monitoring of the engine is performed in which the current torque is compared with a reference value.  During the plausibility test, the lambda value of the exhaust gas upstream or downstream of a catalytic converter is checked to determined if it lies below a threshold.
