Abstract: Dot matrix displays which are capable of graphics permit any desired point of a display field to be highlighted by simultaneously actuating the associated column and line. Dot matrix displays of this kind permit the representation of characters of different sizes at any desired point of the dot matrix display but are however very expensive. The new device is intended to permit the representation of numerals of different sizes at a lower cost. In a two-line dot matrix display divided up into individual dot matrix fields, each numeral is composed of bar-shaped basic patterns in such a way that the basic patterns displayed on adjacent dot matrix fields form the numeral to be displayed in the manner of a 7-segment display. The numerals formed in this way are two dot matrix fields high and three dot matrix fields wide. Each basic pattern is displayed on a separate dot matrix field. The display device is particularly suitable for microprocessor- controlled measuring devices. <IMAGE>

Title: Gaiter
Inventor: DATSON IAN ARNOLD
IPC: A43B23/06
Filed: 1988-03-04
Abstract: A boot or shoe has a gaiter, the lower end of which is permanently affixed by a waterproof join to the boot or shoe's outer surface, circumscribing the said boot or shoe above the sole. The gaiter has an opening extending down from the top, and a fastener, which when closed helps to keep the gaiter in an upright position on the wearer's leg. A gusset is disposed inwardly of the opening and forms a tubular shape when the fastener is closed. A pull cord or other closure at the top of the gaiter is operable to constrict the gaiter's upper periphery around the wearer's leg. This closure inhibits the flow of water into the boot or shoe. When not required, the gaiter folds down around the ankle of the wearer's leg.

Abstract: In a real-time computer-image generation system, processing resources for manipulating polygons that define objects are generally limited. This results in a trade-off with respect to the amount of detail to be displayed in an object versus the number and type of objects to be displayed. In order to save processing resources, the value of a predetermined viewing criterion is used to determine when an object can be represented by a single polygon. The single polygon is rotatable about a predetermined number of axes for maintaining a predetermined relationship with respect to a view-point. Since processing resources are saved by using a single polygon, additional objects and/or more detail may be included in a display.

Abstract: In a code error detecting method, at the time of recording, a sum of n sets of information polynomials of code words of Reed-Solomon codes constituted by m data symbols (D i,j ) each of which is constituted by h binary bits and (g - m) error correction parity symbols (E i,k ) is divided by a generator polynomial to obtain a residue polynomial. The coefficients (C 3 , C 2 , C 1 , Co) of respective degrees of the residue polynomial thus obtained are recorded as the error check parity symbols. At the time of reproducing, data symbols  (D i,j ) constituting the n sets of information polynomials are corrected by using (g - m) error correction parity symbols (   i,k ) A result of addition of n sets of information polynomials thus corrected is divided by a generator polynomial to obtain a residue polynomial. The coefficients (C 3 , C 2 , C 1 , C 0 )of respective degrees of the residue polynomial thus obtained are compared with the error check parity symbols ( ), which have been subjected to correction, so as to detect the presence or absence of an error.

Abstract: A monolithically integrated audio amplifier which is commutable from a stereo configuration to a bridge configu­ration and viceversa may have only seven pins, namely: two output pins, two input pins, a supply pin, a ground pin and a SVR pin. It comprises two operational amplifiers which may both have two distinct input differential stages, a first input differential stage being fedback according to a stereo configuration while the other input differential stage being fedback according to a bridge configuration of the two operational amplifiers. A comparator with an inter­nally fixed threshold determines, in function of its output state, the switching on or the switching off of one or the other of said two distinct input differential stages of the two operational amplifiers and therefore either a stereo configuration or a bridge configuration of the audio ampli­fier. The input terminal of the comparator may be connected to an input pin or to the SVR pin of the amplifier and a biasing DC voltage level may be imposed thereto through external biasing means for selecting the desired configura­tion.

Abstract: The regulation of the output voltage of a voltage multi­plier driven by a ring oscillator, an inverter of which is substituted by a NOR gate for providing a terminal through which stopping the oscillation, is effected by controlling the oscillation frequency in function of the current delivered by the voltage multiplier by means of a transistor T1 working as a current generator connected in series with a regulating chain of series-connected diodes by biasing the gate of the transistor with a constant voltage Vref, thus imposing a reference current Iref through the transistor. The voltage signal across the transistor is fed to the in­put of a first inverter with a preset triggering threshold and the output signal of the inverter is fed through an am­plifying and phase-regenerating stage to said terminal for stopping the oscillation of said NOR gate of the ring oscil­lator. When the discharge current through the regulating chain becomes greater than the imposed current Iref, across the transistor T1 a voltage signal develops which, beyond a certain threshold, determines the switching of the inverter and, through the amplifying and phase-regenerating stage, causes a stop of the oscillation which resumes only when conduction through the regulating chain stops. At steady state the oscillation frequency will result controlled so as to maintain constant the output voltage of the voltage multiplier and to limit the discharge current through the regulating chain thus limiting power consumption.

Abstract: The present invention relates to a method and an arrangement for producing rapid cross-ignition of prefer­ably elongate powder or pyrotechnic charges, such as the propellent charges in impulse motors for correcting the trajectory of shells, rockets and missiles. According to the invention, the cross-ignition is produced by initia­tion of an elongate, extremely fast-burning or detonating primer charge (28-33 or 34-39) with an extremely low explosive force which has been arranged in direct contact with at least part of the periphery of the propellent charge (7-12 or 13-18). The primer charge characterizing the invention can thus be given the form of a tube (42) whose cross-ignition effect is advantageously comple­mented by an inner, more slowly-burning powder core (43) which is combusted with deflagration.

In the second measuring step, the front half cell (1) is also filled with electrolyte (5), and both the rear photocurrent I2 with the now negligible influence of S, and the front photocurrent I1 are measured. From the photocurrents measured, the speed of recombination can be calculated with the aid of a mathematical formula. The local distribution of the speed of recombination is obtained with point-shaped irradiation and screening over the crystal wafer (3). …<IMAGE>…
