Title: Artificial heart
IPC: A61M60/894
Filed: 1986-11-07
Abstract: The present invention relates to an artificial ventricle, with bellows, making it possible to overcome the drawbacks of artificial hearts hitherto produced, in particular deterioration of the components present in the blood, and thromboembolism phenomena. On the artificial heart taken as a descriptive example (pl 1/6), the ventricles are U-shaped, and are each fitted with two bellows and cross over. The alternate closure of the entry and the exit is brought about either by conventional valves or by a pneumatically or hydraulically controlled device. The control chamber is completely independent, and can operate using various power supplies. This ventricle or this artificial heart has the purpose of replacing a defective heart, and can be used in human cardiac surgery either for intracorporeal implantation or for extracorporeal assistance. The assistance may involve both ventricles or one alone. The system should allow, if required, autonomy of the subject.

Patent FR-2609335-A1 (FR)
Inventor: CLEMENT GILLES
IPC: G01P3/42
Filed: 1987-01-05
Abstract: A system determines the movement of a track vehicle along the ground, the track vehicle having at least a first rotatable, endless track for supporting the vehicle on the ground, a drive for causing the movement of the vehicle, and a turning system for changing the direction of the movement of the vehicle. The system has a first traction-improvement device for mounting on the track vehicle. It bears on an inner-surface side of the first track with sufficient pressure for a small-surface portion on the opposite side of the first track to engage the ground with a higher pressure than any other portion of the first track, whereby to locate a pivoting axis of the track vehicle in the vicinity thereof. A first speed sensor for mounting on the track vehicle in the vicinity of the small-surface portion on the opposite side of the first track senses the speed of movement of the track vehicle along the ground only in the direction of the rotation of the first track and provides a first information thereof, whereby the movement of the track vehicle may be deduced therefrom. Preferably the vehicle has two tracks, and the system has two such traction-improvement devices and speed sensors respectively for the two tracks.
