Title: Fully automated lawn mower
Inventor: DRESSEN NORBERT
IPC: A01D34/00
Filed: 1989-06-09
Abstract: In order to facilitate work in the garden, use can be made of the fully automatic lawn mower for the independent mowing of lawn surface areas of any size. Due to the free selection of possible laying options of the iron bars, which magnetically predetermine the travel path of the lawn mower, any shape of the lawn surface area can be followed. After a single starting signal, the lawn mower automatically begins with the mowing operation. Wherever mowing in parallel tracks is necessary, the iron bars have to be correspondingly laid beforehand, and the lawn mower independently carries out the track change. After the mowing operation is completed, the machine independently returns to the starting location, where it simultaneously empties the grass catcher and recharges the battery, with the result that the lawn mower is again ready for the next mowing operation.

Patent DE-4030418-A1 (DE)
Inventor: HOEHNE GERD DIPL ING
IPC: F02P3/04
Filed: 1990-09-26
Abstract: The proposal is for a power output stage with a Darlington circuit (11, 12) for switching an inductive load, especially the ignition coil of an internal combustion engine. In order to predetermine the mode of operation of the power stage, there is a switch (24) bypassing the base-emitter path of the Darlington circuit (11, 12) which is closed when the output stage is switched off and opened when the output stage is switched off with limited voltage. The output of a voltage divider consisting of at least two resistors (16, 18) and bypassing the switching path of the Darlington circuit (11, 12) is connected to the junction between the switch (24) and the base of the Darlington circuit (11, 12), whereby the switch (24) is connected in parallel to a part (18) of the voltage divider. With the switch (24) open, the Darlington circuit is again controlled via the resistor (16) when a low limit voltage of e.g. 35 V is reached, so that, in the event of the drive of an ignition coil, spark-free switch-off is obtained. Only very few simple and cheap components are needed herefor.
