Abstract: A system (10) and method for matching a set of detected points (26) to a reference constellation (20). A programmable processor (14) receives detected coordinate locations from a sensor (16) and reference coordinate locations from a reference storage device (12). The processor (14) performs a coordinate transformation from the reference coordinate frame to the detected coordinate frame and contructs a table of possible matches. Potential matches are found from the possible matches which have their difference vectors below a predefined threshold. These possible matches are then placed in a match matrix histogram (30) which is further refined to eliminate all but the best matches. The final matching then may be used to find a particular aimpoint (24) in the detected constellation (26).

Abstract: A light shutter system (10) incorporates a liquid crystal cell (12) operating as a variable optical retarder to selectively produce opaque and transmissive optical states corresponding to the respective first and second amounts of system optical retardation. The cell switches between a residual amount of retardation and an increased amount that equals the sum of half-wave retardation and the amount of residual retardation to provide a shutter system whose system retardation switches between zero retardation and half-wave retardation and thereby produces opaque and transmissive states with an optimal contrast ratio. The cell is positioned between a linear polarizing filter (14) and an elliptical analyzer (16), the latter including a linear polarizing filter (20) and an optical retarder (18) of fixed value. The transmission axis of the linear polarizing filters are angularly displaced relative to a projection of the optic axes of the cell by an amount that provides maximum light extinction in the opaque state. Maximum output light transmission in the transmission state is achieved by establishing for the cell an optical thickness that exceeds half-wave retardation by an additional amount equal to the residual retardation. Other preferred embodiments that provide equivalent performance are described.

IPC: G05F1/455

Abstract: To start the automatic control of the operating current of a current source when the circuit is switched on, it is proposed to control the current source by presetting the circuit parameters in such a manner that the current produced on switch-on of the circuit tends towards a preset nominal value. The current control is only brought into action when the difference between the actual value and the nominal value of the current drops below a particular limit value. For this purpose, a control device is used which exhibits a voltage controller (7), a current controller (8) and a switch-over device (9) with threshold circuit. The switch-over device (9) generates a switching signal (s) which effects the switching-over from the initial voltage control to the current control as soon as the current exceeds a particular threshold value after the switching-on of the circuit. This makes it possible effectively to avoid switching-on current surges even when the circuit exhibits a current source controlled with an intermittent adjusting effect, for example a current source controlled by phase-control of valves. This effect can be improved further by the current control initially coming into action with an impressed actual value corresponding to the nominal value of the operating current during switch-on.

Abstract: The invention relates to a method for the separation of tobacco parts consisting of tobacco rib pieces (rib pieces) from tobacco parts which consist of tobacco fibres that are stuck, agglomerated or folded together. 
<??>The invention resides in warming the tobacco fibres by passing in steam, as a result of which the tobacco fibres which are stuck, agglomerated or folded together are substantially detached from each other and opened. The tobacco parts thus steamed, warmed and possibly moistened are then subjected to a screen operation, in which the rib pieces are separated from the detached and opened tobacco fibres. 
<??>The advantage of the method according to the invention resides in the fact that the tobacco fibres, after they have been detached from each other and opened and separated from the rib pieces, are reused, so that the losses of expensive tobacco can be reduced.

Abstract: 1. Method and device for fast winding of a recording tape. 2.1 A system is presented, comprising a method and a device suitable for carrying out this method, which allows a fast winding of a recording tape from a first reel onto a second reel. In this arrangement, the winding time is to be as short as possible and the mechanical stressing of the tape as well as the formation of loops are to be reduced. 2.1 According to the invention, a final rotational speed, from which the tape can be braked without excessive mechanical stress by means of a braking device, is determined. Furthermore, a maximum desired deceleration is determined, which is usually achieved by reduced activation of a driving means used (electric motor) without use of the said braking device. This desired deceleration is chosen in such a way as to avoid any formation of loops and to detect contacts of the tape with sensors which detect special marks, such as for example the beginning of a film on a video tape. According to the invention, the unwinding first reel is accelerated for as long as the remaining winding time is sufficient for decelerating at the desired deceleration to the final rotational speed. The remaining winding time is compared with the required time by comparison of terms into which operating variables such as the radii of the first and second reels, the associated rotational speeds and the like are entered along with the final rotational speed and the desired deceleration. 2.3 The system according to the invention can be used with preference for winding video cassettes. <IMAGE>

Abstract: A method for ( in situ ) measuring a sample of an air-permeable material having a fine granular material located within its pores eg toner in a 2 component developer and, in particular, for determining the concentration of the fine granular material within the sample includes the steps of transmitting an acoustic slow wave of known amplitude and phase velocity, through the sample, detecting the attenuation and/or propagation velocity of the wave after passage through the sample, and determining the concentration of the fine granular material in the sample from the changes in the acoustic signal. The apparatus uses two acoustic transducers (86,88) with the sample between them. In a second method changes in the resonant frequency of an acoustic transducer (98) immersed in the sample are used to monitor changes in the acoustic impedance of the sample and thus the toner concentration.

Abstract: For manufacturing multilayer ceramic electronic parts, first 20 to 50% by volume of binder is added to a ceramic powder, which in turn is dispersed in a solvent to prepare a slip (S21) after which a green sheet is formed from the slip by the tape casting method (S22). Next, the sheet is cut to pieces (S24) of a fixed size for stacking (S.25) in multilayers in a metal mold. Then said metal mold is pressed under a low pressure of not more than 100 kg/cm² (S26) to laminate the sheets into a green multilayer. Subsequently said green multilayer is heated to thermally decompose the binder included therein (S27), and after the cold isostatic pressing (S28) is applied to the green multilayer, it is sintered (S29) to obtain a sintered matter. Further the sintered matter is processed in the following process (S30-S34) to obtain the object mutilayer ceramic electronic parts. Since the pressure which is applied in pressing of the sheets for laminating them is low, the porosity of the green multilayer becomes high enough that the following thermal decomposition of the binder is easily performed. Further, by applying cold isostatic pressing subsequently to the green multilayer, the post-sintering density of the sintered matter becomes high enough to provide adequate characteristics of the matter.
