Abstract: The storage space of the instant system is considered, for refresh purposes, to contain 512 groups of 26 bit digital words with each group containing 128 such words. Memory refresh is implemented by sequentially refreshing the groups of digital words at the rate of one group every 2.8 microseconds, giving an expected total memory refresh time of approximately 1.43 milliseconds. A particular digital word from each group of digital words refreshed is read from the memory and transmitted to a parity check circuit which generates fault signals for any digital word having faulty parity. At the end of each of the approximately 1.43 millisecond refresh cycles, the particular word read from each group refreshed is changed so that at the end of 128 full refresh cycles (approximately 184 milliseconds), the parity of every digital word in the memory has been checked. Further, circuitry is provided to store the location of the first failing digital word in a trap register in response to an indication of faulty parity.

Abstract: The invention relates to a boarding device for vehicles for easing the entering from the ground 24 to the cabin floor 1. A parallel connecting arm system 10, 11 carries a lifting plate in the form of a tread 15. A compressed air cylinder 20 acting between the vehicle 3, 6 and the connecting arm system 10 lifts the lifting plate 15 with a person standing thereon from a lower position at a convenient rise of step a above the ground level 24 to an upper position at a convenient rise of step b below the level of the cabin floor 1. Simultaneously with the lifting c of the lifting plate 15, the latter is displaced outwards z outside the contour of the vehicle, such that entering the cabin is facilitated. The cylinder 20 is manoeuvred by means of a solenoid valve, the solenoid of which is connected in series with two switches. One of those is manually operable, while the cabin door automatically actuates the other. Hereby, the lifting plate 15 will always take up its lower position, drawn inside of the vehicle contour, when the door is closed, but will be lifted automatically to its upper position when the driver opens the door from inside. <IMAGE>

Abstract: The electronic filter has three integrating operational amplifiers (12, 14, 16) connected in series. An input voltage (Vin) to be filtered is supplied during alternating clock pulses (phi, phi') to the first integrator (12) from a capacitor (30) and to the capacitor for storage, respectively, by way of MOS switching devices (18-24). Capacitances (40, 44) are connected in a feedback loop of the first amplifier, of which the output is connected via capacitor (68) and MOS switches (58, 62, 70, 72) to the inverting input of the second integrator (14). The stray capacitances are eliminated effectively by the additional pair of switches for each switched capacitor, by the alternate charging and discharging of the stray capacitors on the alternate clock pulses. A third order elliptic filter characteristic is achieved having two complex conjugate poles, a real pole and two complex conjugate zeroes. Magnitudes of the zeroes are not affected by the capacitor valves alpha i, where i equals 1, 2... . In the transfer function, the magnitude of the transmission zero is the constant term of the quadratic factor in the numerator and is always unity no matter what the capacitor values are.
