Title: Method and interface for real-time digitizing of video signals.
Inventor: BRUN-BUISSON ANDRE MARCEL
IPC: G06T1/00
Filed: 1982-09-20
Abstract: After separating the line and frame synchronising pulses, the analog luminance signal coming from a camera is compared continuously with a chosen threshold value. The continuously changing binary signal thus obtained is sampled at a fast rate, in a time relation with the line synchronising signals, and this for each frame, at a rate of C samples per line over L lines per frame. In synchronism with the sampling is produced a corresponding succession of address orders, at a rate of one per p sampling orders, p being a submultiple of C. A digital memory MI is filled by the words thus defined, at the address correspondingly defined. On command, the procedure for writing image information to memory is interrupted at the start of a new frame, and the digital image information is extracted in order to be transferred to an associated processor.

Title: Lifting barrow for handling
Inventor: LEMAIRE GHISLAIN
IPC: B62B1/22
Filed: 1982-11-16
Abstract: The invention concerns a barrow for handling. This barrow is constituted by a fork 11, equipped with two independent wheels 9 and 10 fixed perpendicularly to two uprights 7 and 8 on which is mounted a sliding frame 1, equipped with lifting arms 2 and 3, linked by a chain 4 to a bracing lever 5 whose articulation spindle 6 is securely fixed to the uprights 7 and 8. The spacing of the fork 11 has been determined in order to leave the free passage for a crate, and the spacing of the lifting arms 2 and 3 as well as their distance with respect to the ground, have been determined in order that they can be placed under the rims or the handles of the crates. It is then sufficient to knock the bracing lever 5 downwards, in order to obtain the lifting of the crate before moving it. This barrow is intended mainly to handling crates of harvested crops.
