Patent DE-19858826-A1 (DE)
Inventor: IGEL GUENTER
IPC: G01R33/038
Filed: 1998-12-19
Abstract: The invention relates to a capacitive magnetic field sensor. This sensor is provided with a first electrode (2) and a second electrode (3) which are interspaced and which form a measuring capacity. The first electrode (2) is arranged on a first substrate body (4), and the second electrode (3) is arranged on a second substrate body (5), whereby the second substrate body (5) is configured as a deformable membrane in the vicinity of the second electrode (3). A magnetic body (6) is arranged in the vicinities of the second electrode (3) and of the membrane, and is connected in a rigid manner to the membrane and to the second electrode (3). By virtue of this rigid connection, the influence of an external magnetic field on the magnetic body not only provokes a displacement of the magnetic body (6) but, by being connected in a fixed manner to the membrane and to the second electrode (3), provokes a displacement of the same. The displacement of the second electrode (3) alters the distance to the first electrode (2) and thus the measuring capacity, which acts as a measure for the externally applied magnetic field. The capacitive magnetic field sensor is characterized by having a very small overall size, a high level of mechanical stability, and a low dependence on temperature.

Title: Method of transaction handling in distributed configuration database
Inventor: TRAVERSAT BERNARD A
IPC: G06F9/46
Filed: 1999-06-08
Abstract: The method involves receiving transactions initiated by an application via an interface with public and private segments and performing the transaction w.r.t. the configuration database.
