Patent DE-4141224-A1 (DE)
Title: Heating load control method for surface heating element e.g. for heated automobile seat - using full heating load for initial heating-up and reduced load for temp. maintenance
IPC: G05D23/19
Filed: 1991-12-13
Abstract: The heating load control system allows the max. heating load to be supplied to the surface heating element for an initial heating-up interval, which has a base duration inversely proportional to the detected ambient temp. of between 0 and 15 min. and a reference duration dependent on the selected heating temp. of between 2 and 12 min. The heating load is reduced by between 50 and 90 per cent at the end of the heating-up phase, to maintain the selected temp, with the max. heating load provided for a calculated temporary interval, upon the selected temp. being switched to a higher value. The duration of the latter interval is dependent on the difference between the new selected temp. and the previous temp. USE - For maintaining automobile seat at comfortable temp.

Patent DE-4209761-A1 (DE)
Inventor: WOLF ANDREAS DR ING
IPC: H04B3/46
Filed: 1992-03-23
Abstract: The invention relates to a process for finding the transmission properties (H(jf)) of an electric line (2) in an ISDN system in which a test signal (m(t)) is applied to one end of the line (2) and at the other end the reception signal (g(t)) produced by the test signal (m(t)) is evaluated. In order to be able to conduct such a process with a test signal with a crest factor of one with relatively little cost, the test signal used is a binary, bipolar random numerical sequence signal (m(t)) with the crest factor one and the reception signal (g(t)) is scanned at time intervals corresponding to the period of the test signal (m(t)) and subjected to a Fourier transformation to provide a spectrum signal (G(jf)); the latter is complexly multiplied by a reference spectrum Mi(jf) to provide an output signal (H(jf)) which provides a measure for the transmission properties of the line (31).
