Inventor: MICHI HARALD
IPC: G01S15/931
Filed: 1999-12-30
Abstract: The invention relates to a method for mismatch detection in a vehicle-sensor system, wherein a signal is transmitted and wherein signals reflected by a standing object are received. The transmitted and received signals are used to determine a relative angle and a relative distance or a longitudinal and a transverse mismatch between a detected object and a reference axis of a vehicle and a relative speed between a detected object and a vehicle. The relative angle, the relative distance and the vehicle speed or a longitudinal mismatch, transverse mismatch and vehicle speed are used to calculate a correction value for the relative angle.

Inventor: BURET ANDRE G
IPC: A23K1/16
Filed: 1996-05-09
Abstract: The use of epidermal growth factor for a manufacture of a
medicament for treating or preventing gastric ulcers in an
animal susceptible to or suffering from such ulcers is
described. Epidermal growth factor (EGF) can be used as a
gastrointestinal therapeutic agent. As such, EGF is useful
in preventing gastrointestinal colonization by pathogens
such as  Helicobacter pylori . An important use of EGF is
therefore in the prevention of bacterial colonization at
gastric ulcer sites which contributes to the chronicity of
the ulcer. EGF can also be used in accelerating the healing
of gastric ulcers.
