Abstract: A vehicle chair has a neck support ( 4 ), which by means of a support mechanism ( 5 ) is mounted movable relative to the back ( 3 ) of the chair, so that during rear end collisions with the help of the back of the traveller and a maneuvering means ( 10 ) in the chair to be forced forwards in order to meet and intercept the head of the traveller. This maneuvering means ( 10 ) is connected to the frame ( 9 ) in the back of the chair by means of a link mechanism ( 11 ), wherein the connection ( 13 ) of the link mechanism ( 11 ) to the frame ( 9 ) is situated higher than the connection ( 14 ) of the link mechanism ( 11 ) to the maneuvering means ( 10 ).

24 Jul 2000TL;DR: The theory of noise modulated radar is treated, point target response, side-lobe level, and time compression due to motion effects are analysed, and degrading effects from additive noise are analysed.
Abstract: Presently, there is an increasing interest in noise modulated radar in a wide spectrum of applications, such as surveillance, tracking, altimetry, and sub-surface profiling. Wide-band signals with high range resolution, reduced ambiguities and high ECCM performance can be achieved. In this paper, the theory of noise modulated radar is treated. Point target response, side-lobe level, and time compression due to motion effects are analysed. The processing involved correlates the received signal and the delayed reference signal. An alternative method correlates only their signs, making it possible to reduce the requirements on the analog-to-digital converters to one bit. Both approaches are studied and degrading effects from additive noise are analysed.

TL;DR: The detection range for a blackbody point target is considered, and an integrating photon detector is assumed, and the signal-to-noise ratio is expressed by use of photon-flux quantities.
Abstract: The detection range for a blackbody point target is considered. An integrating photon detector is assumed, and the signal-to-noise ratio is expressed by use of photon-flux quantities. An equation for range, valid for the case of a background-limited photodetector, is formulated, and the solution to this equation is dependent on two parameters only: the extinction coefficient representing the atmospheric attenuation and one other parameter that includes other relevant system parameters in a simple way. This means that range as a function of different parameters can be conveniently summarized in one graph. Relations between different parameters are also discussed.

14 Mar 2000TL;DR: In this paper, an internal combustion engine with variable compression, comprising a crankshaft bearing crankcase part (2) and a cylinder-receiving part (6) arranged tiltably thereon by means of a tilt axle bearing (8) on one side of the engine and a tilt mechanism (10) on the other, opposite side of an engine, is described.
Abstract: Internal combustion engine with variable compression, comprising a crankshaft-bearing crankcase part (2) and a cylinder-receiving part (6) arranged tiltably thereon by means of a tilt axle bearing (8) on one side of the engine and a tilt mechanism (10) on the other, opposite side of the engine, which cylinder-receiving part (6) supports a cylinder head (14) which is securely connected thereto, preferably with camshafts mounted therein. Arranged between the crankcase part (2) and the cylinder-receiving part (6) there are prestressing members (38) which force these engine parts apart and work to counteract the occurrence of bearing play in the tilt axle bearing (8) and in the tilt mechanism (10) when compression-modifying tilting movement between the cylinder-receiving part (6) and the crankcase part (2) occurs during running of the engine.

13 Sep 2000TL;DR: In this article, a fitting has a guide on the upper free end of an arm which is directed roughly upwards and which can bend under load from the belt in the event of a crash.
Abstract: The fitting has a guide (10) on the upper free end of an arm (11) which is directed roughly upwards and which can bend under load from the belt in the event of a crash. A locking device (13), which is activated in the event of a crash, is between the guide and the belt winding (12) device. This prevents the belt being pulled out.

15 Jun 2000TL;DR: In this article, an automotive gearbox has an input shaft (10) to a clutch to a drive shaft, and a third shaft (14) parallel to the first two, where the output shaft (12) has seven cogs of which five are fixed to the input shaft, while the other two cogs rotate on the shaft.
Abstract: An automotive gearbox has an input shaft (10) to a clutch to a drive shaft. One output shaft (12) is located parallel to the input shaft and thence to the vehicle drive wheels (22, 24), and a third shaft (14) parallel to the first two. The gearbox has six forward gears. The input shaft (10) has no more than five cogs of which two (26, 28) are fixed to the shaft and operate in the first and second gears. The other cogs turn on the shaft. The output shaft (12) has seven cogs of which five are fixed to the shaft (12), while the other two cogs (48, 50) rotate on the shaft. The third shaft (14) has two or three cogs, of which one (54, 74) is fixed to the shaft, and one or more (56, 76, 78) rotate on the shaft.

Abstract: not available for EP0796197Abstract of corresponding document: WO9619381A hood detonation system for blasting two hoods in a two-seated aircraft is described. It comprises a first detonation cord (3) detonable by means of initiation and attached to the first, front hood (1), and a second detonation cord (4) detonable by means of initiation and attached to the second, rear hood (2). The hood detonation system is in particular characterized by a protective balloon (19) inflatable by initiation of a gas generator essentially simultaneously with the initiation of the detonation of the second detonation cord (4), and adapted to prevent splintered parts from the second hood (2) to move into the space inside the second hood.
