Patent SE-8602141-D0 (SE)
Inventor: NORBERG K A
IPC: F42C14/08
Filed: 1986-05-12
Abstract: The invention relates to a method for determining whether a tracked vehicle 10 is passing over or to the side of a measurement point where a 3-axis vibration sensor 12, such as a speed or acceleration sensor, is buried or fixed in the ground at the surface of the ground 11, so that it senses the particle movement of the ground in three directions x, y, z at right angles to one another. The output signals of the vibration sensor 12 are sampled at regular time intervals and the three signal samples taken in each sampling operation are combined to form a resultant vector which indicates the movement of the ground at the measurement point in terms of magnitude and direction. According to the invention, the directional constancy of the resultant vector, which means its tendency to lie in one and the same direction from sample to sample during a given time interval, is monitored, and a mine 14 located at the measurement point is tripped in the event of an abrupt reduction in directional constancy. An explosion is triggered in the event of a change to a more non-uniform movement of the resultant vector. In order to obtain a measurement of directional constancy, what is known as the cross product between two consecutive resultant movement vectors can be calculated, and the mean value of a number of such cross products can be formed over a given time interval in order to obtain what is known as a normal vector for a mean plane for the movement of the vector, a reduction in the directional constancy of this normal vector triggering an explosion. <IMAGE>

Abstract: An air permeable target electrode (M) is arranged concentrically around a wire-like corona electrode (K). The electrodes are connected to a d.c. voltage source (3) which causes a corona discharge at the corona electrode and an ion wind through the target electrode. The target elecrode is cylindrical, and air flows axially into it through one or both of its open ends. The air exits radially through its air permeable wall. The target electrode may be divided into two separate parts arranged concentrically around the corona electrode (K) in a spaced relationship. In this case, the air flows radially inwards through the interspaces between the different target parts, and the air exits radially through these parts.

Abstract: A flush control valve (10) for metering a predetermined amount of flush fluid, or other liquid, to a facility, such as a urinal, to be flushed. The flush control valve (10) has a push button cap (166) that is actuated to cause the primary valve assembly (33) to open and distribute the flush fluid from the inlet chamber (35) of the flush control valve (10) to the outlet chamber (36) of the flush control valve (10). Depressing the push button cap (166) activates a timing assembly (109), the interior working components of which do not come in contact with the flush fluid controlled by the flush control valve (10), thereby eliminating corrosion to that critical portion of the valve (10). The timing assembly (109) is pneumatically operated and is effective through a diaphragm (108) to actuate a pilot valve assembly (83) which controls the opening and closing of the primary valve assembly (33). By virtue of the interaction between the diaphragm (108) and the stem valve element (79) in the pilot valve assembly (83) and the pressure of the flush fluid within the valve (10), and the control effected by a bleeder sub-assembly (130) in metering the flow of pneumatic fluid from a timing chamber (115) to an energizing chamber (120), the timing assemlby (109) is returned to the unactuated disposition at a rate sensitive to the pressure of the flush fluid so that a substantially constant volume of flush fluid is delivered by the flush control valve (10) over a wide range of flush fluid pressures.

Abstract: A method and an arrangement minimizes skew in digital synchronous systems. The arrangement includes N number of driver circuits, each of which has a P number of buffer units, of which each has an input and an output. Each driver circuit has a delay of  delta 1,  delta 2,  delta 3,  delta 4 . . .  delta N. Of these buffer units, N-1 buffer units are reserved while the inputs of the remaining buffer units P-(N-1) are connected mutually in parallel. The reserved buffer units are used as follows. A signal deriving from a signal source is applied to an input of a first buffer unit in each of the N-number of driver circuits, where the signal is subjected to a delay. The one-time delayed signal from a driver circuit is then delayed once, and only once, in the reserved buffer units of each of the remaining driver circuits. This procedure is repeated for each of the once-delayed signals on the outputs of the first buffer unit in each of the remaining N-1 driver circuits. Output signals which are mutually delayed by a time delay of  delta 1+ delta 2+ delta 3+ delta 4 . . .+ delta N appear on the outputs of the buffer units in each of the driver circuits, the inputs of these buffer units being connected in parallel.

Abstract: A device and a method for deviation determination for use during transfer of a phase shift modulated information-carrying signal between a transmitter and a receiver. The deviation determination is based on the presence of phase-linear segments, i.e., parts of sequences of phase changes that have the same phase change. Segments having three or more consecutive phase changes of the same value are extracted. An identification of the filtered-out segments is performed in order to determine which nominal phase-linear sequences the segments belong to. After this, the deviation and possibly a correction signal can be determined.

Abstract: A conventional seat belt rolling-up frame (101) is equipped with an electric motor (112) for tensioning the seat belt both to a comfort value for normal rides and to high forces in emergency situations. The motor can be activated as often as required without any need for maintenance. The power required to drive the motor is obtained from a high voltage capacitor (114) storing sufficient energy. The seat belt will then be independent of the resistance of the starter battery of the vehicle in which the seat belt is mounted. All electronic parts connected to the stator phases of the motor and to the capacitor are contained in a shielding enclosure (104, 119, 124) resulting in low emissions of high frequency electromagnetic noise. The motor is mounted at a first end of a belt roller shaft (102) to drive this shaft directly. The mounting is made so that the motor and the shaft will be displaced by the very high belt tensions created by a serious crash. Cog means (120) can then lock the rotor of the motor and thereby the shaft. Signal processing circuits (108, 109, 107) for low voltage signals are located inside a casing (101e) attached at a second opposite end of the shaft.
