Abstract: A circuit for detecting the current in an MOS type power transistor comprises a detection transistor (T2) connected with its drain and gate in common to the power transistor (T1) and having characteristics such that the current flowing through it is equal to a fraction of the current (I1) flowing through the power transistor (T1). Downstream from the detection transistor (T2) is a comparison transistor (T6, T13) for comparing a first current (I3), which is equal to a fraction of the current flowing through the detection transistor, with a second or reference current (Ig1) having a pre-set value. The comparison transistor (T6, T13) produces a detection signal of the value of the current in the power transistor (I1) in relation to the difference between the first current (I3) and the reference current (Ig1).

Abstract: A tractor-mounted three-point hitch for pulling a tillage implement is controlled by a closed loop including draft sensors for sensing the draft on the hitch and providing a draft feedback signal. An operator-controlled quadrant lever provides command signals for commanding the positioning of the hitch relative to the ground. During rapid hitch movement commanded by movement of the quadrant lever while the implement is above the ground, the draft feedback signal, which is normally filtered to eliminate frequencies above about 3.2 Hz, is more heavily filtered to eliminate frequencies above 0.5 Hz. This makes the loop less sensitive to the draft feedback signal and reduces vibrations which would otherwise occur because of oscillations in the draft feedback signal. The oscillations are caused by interaction of the weight of the implement bouncing because of the pneumatic tires on the tractor, and movement of the hitch to correct for the apparent change in draft.

Abstract: This arrangement enables the identification of a plurality of vehicles (4) and determination of the instant of their passing over a reference line (30). It includes a moving station (1) mounted on the vehicle and a fixed station (2) arranged alongside a racetrack (3). The fixed station broadcasts a low-frequency synchronization signal of period T which is received by the moving station, the latter in turn broadcasting a series of signals of duration Tn located in a predetermined rank relative to the time t.sub.o marking each start of period T. Conjointly the moving station allocates an identification code peculiar to a given moving object to each signal Tn. The signals received by the fixed station are stored in a memory which for each signal memorizes its absolute time, its association with a given vehicle and its amplitude. The arrangement is used for motor vehicle races which include a large number of competitors.

Abstract: This race timing apparatus of the video finish type includes a photo sensitive CCD bar (5) which may be read at a predetermined frequency in correspondence with the run past speed (Vi) of the image of the race. The images are stored and visualized by means of a commercial recorder (22) and monitor (23) of a fixed standardized sweep frequency. Since the image acquisition frequency by the bar is not synchronous with the visualization frequency, one proceeds with the generation of image parts using buffer memories (19, 20), the image parts being next stored in an image memory (21) and then read in a discontinuous manner by jumping over image parts in synchronism with a standard TV sweep. The apparatus enables the offering of a system at a low overall cost price since it employs a recorder and a monitor currently obtainable on the market.

Abstract: A linear detector selectively detects successive line images from different angles while the linear detector and a radiation source are rotated about a patient. Radiation-transmission images are generated and detected and converted to computer-grabbed images by a computer which acquires, processes, stores and reconstructs the images. A visual monitor display reconstructs video images including a planar image and tomographic images representing sections orthogonal to the planar image. Selectively-positionable field-delineating lines corresponding to intersectional outlines between a simulation beam and the planar image are overlaid on the planar image. Beam-delineating lines are updated by the computer to correspond to intersectional outlines as the field-delineating lines are positioned.
