Title: Extension device for cars
Inventor: WANNERT MICHAEL
IPC: B60P3/34
Filed: 1981-07-10
Abstract: The invention relates to an extension device which makes possible a sleeping compartment for two people. The usual canvas extensions have the disadvantage of not being very stable, of being poorly insulated and not secure against theft. The invention is based on the object of eliminating these disadvantages and of inventing a practical, robust extension device. The invention is characterised by the fact that the extension device is composed of a floor panel (1) which is fastened to the luggage compartment floor by hinges. Fastened to this panel by hinges (3) are support panels (2), side walls (4) and a rear wall (5) with protruding edges (6), which can all be folded up to form a package approximately 15 cm thick and can then be pivoted into the luggage compartment. When putting up and taking down the extension the luggage can remain in the luggage compartment. The side walls are secured from the inside by latches (7). The car rear wall serves as a roof and is rendered rainproof by a sealing strip (9). This extension device is stable, rainproof, wind resistant, secure against accidents and theft, is quickly put up and insulated against the cold. When the vehicle is used for sleeping, the luggage is placed underneath the floor panel. <IMAGE>

Title: Average-frequency measuring device
Inventor: TAKAHASHI TOSHIRO
IPC: G01R23/10
Filed: 1982-05-22
Abstract: In an average-frequency measuring device, auxiliary gating-out signals are converted into gating-out signals which are either synchronised with input signals or clock signals and which open a first and second gate. The input signals and clock signals passing through the first and second gate are counted by a first and second counter. The frequency of the input signals is calculated from the counts of the first and second counter for multiple occurrence of the synchronised gating-out signal. A third counter is used for counting the number of synchronised gating-out signals, and a minimum counting time is calculated from the counts of the third and second counter and the measuring accuracy set. If it is apparent from the count of the second or third counter that the actual counting time has been exceeded, the measurement is stopped, as a result of which measurement results are achieved, the accuracy of which is above the measuring accuracy set.
