Title: Mechanism for sensing the moving and/or position of tilting panel of a door
Inventor: GUDAT WOLFGANG
IPC: E05F15/53
Filed: 1984-09-13
Abstract: In a device for detecting the movement and/or position of a pivotable door leaf, for example for a door control in a means of public transport, a sensor is arranged in the region of an axis of rotation of the door leaf. The sensor serves for detecting the rotational movement between the door leaf and a part which preferably serves as a pivoting lever for the door leaf and which is also pivotable about the axis of rotation in the region of which the sensor is arranged. During a pivoting of the door leaf, said axis of rotation for the door leaf and for the pivoting lever is likewise pivoted. A relatively large rotary angle detected by the sensor is thereby obtained.

IPC: H01L21/66
Filed: 1990-07-12
Abstract: The invention relates to apparatus and method for determining the carrier concentration profile of the carrier concentration in semiconductor materials, multi-layer semiconductor structures and semiconductor devices. According to the invention, applied between an ohmic contact and a rectifying contact formed on the semiconductor are a d.c. voltage resulting in a reverse bias, and two periodic excitation signals having frequencies  OMEGA 1 and  OMEGA 2. Frequency  OMEGA 1 is greater than  OMEGA 2 such that  OMEGA 1, OMEGA 2, their difference ( OMEGA 2- OMEGA 2) and their sum ( OMEGA 1+ OMEGA 2) are in the same order of magnitude. Two components from the semiconductor's electronic response to the excitation are selected for analysis. The first component is the response to the frequency  OMEGA 1 or  OMEGA 2, and the second component is a first order intermodulation product of one of  OMEGA 1 and  OMEGA 2. Carrier concentration is determined by simultaneous parallel analysis of these first and second components.
