Patent EP-0359220-A2 (EP)
Inventor: CHOU WAYNE W
IPC: G06F21/00
Filed: 1989-09-13
Abstract: Filter networks are incorporated within a software protection hardware device which is plugged into a communications port of a computer which device will select bits or combinations of bits emanating from the communications port resulting from commands of a controlling software in use with the computer which is desired to be protected. The filter networks select the bits of a disguised predetermined control code which when matched with a stored reference code results in an output from the filter used to activate functions within the protection device. The purpose of the code is to prevent an outside observer from determining what activates the security device which prevents the security of the software from being compromised. A stream of bits including a disguised predetermined control code issuing from the computer through the security device are compared with a stored reference code in a programmable memory and when a match occurs an output emanates providing an acknowledgement code to the computer indicating that the hardware device has been plugged in and is a proper one. The stored reference code can be provide by a programmable memory using an intermediate storage register between the programmable memory and the selection network. The intermediate storage register is clocked so that the input refer­ence code of the networks changes in a predetermined manner.   Accordingly, the code is selected by networks changed in accord­ance not only with what is stored in the programmable memory, but also by the content of an intermediate register at any given time, the effect of which is to continually change the reference code by clocking the intermediate register.

Abstract: A zero-IF radio receiver circuit comprises an input filter (3), quadrature mixers (9,10), d.c.-blocking capacitors (24,26) and a demodulator (22). The circuit is partly integrated on a semiconductor chip and an inductive component of the input filter comprises one or more of the chip bond-wires. In order to compensate for the inevitable variation of the inductance of these bond-wires from circuit to circuit part of the signal from the local oscillator (12) is added to the input signal before its application to the input filter and the d.c. component of the resulting output from one mixer (10), which component is representative of the phase shift of the local oscillator signal produced by the input filter and hence of any tuning error of this filter, is applied to a tuning control input (30) of the filter to reduce the error. Alternatively the tuning control signal may be adjusted to maximise the sum of the squares of the d.c. components of the signals in the two IF channels and hence minimise the attenuation produced by the input filter.

Abstract: The invention relates to a circuit arrangement for processing sampled analogue electrical signals, each sample being in the form of an electrical current, the circuit arrangement comprising means for combining, in predetermined proportions, the input sample current in the present sample period with current(s) derived from input sample curent(s) in one or more preceding sample periods, and means for deriving the processed output signal from the combined current produced by the combining means in successive sample periods. 
     The circuit arrangement is formed by a plurality of modules which each generate and accept bi-directional signal currents and which contain current sources so that internally only unidirectional currents are processed. The transistors which conduct signal currents are arranged to be of one conductivity type only. This reduces the voltage requirements at the interfaces between modules.

Abstract: A method for managing data in a data storage library, and a data storage hierarchy suitable therefor, is disclosed. The data storage hierarchy includes an optical library and separate manually operated shelf storage. The optical library includes at least one optical disk drive and a plurality of storage cells for the storage of optical disks. The optical library also includes automatic means for transferring optical disks from the storage cells to the optical disk drives in the library. The host data processor, upon determining that particular data is required to be stored in the optical library, first checks to determine if the optical disks in the optical library currently have the capacity for the storage of such data. If the capacity exists in the optical library there is no problem and the data is stored therein. If the optical library does not have the required capacity, or if the system operator so requires, the optical disk in the optical library which has least recently been mounted on an optical disk drive therein is destaged from the optical library to the manually operated shelf storage. Another disk may then be fed into the optical library for the storage of the data required therein.

Abstract: Trilateral trimming of, preferably folded, signatures 2, which can have different thicknesses, takes place in two steps. First the side located opposite the folded spine is trimmed and then the two remaining sides are simultaneously trimmed. The signatures 2 are each fed via a toothed-belt pair 20 from a storage cassette 1. The format of the signatures 2 to be trimmed can be adapted by means of stops 39. The first trimming takes place by moving the cutting elements, fixed to a plate 90 serving as a slide, along the counter-cutting elements. In the same way, by longitudinal movement of the cutting elements the trimming on the two sides is carried out, the signatures 2 being held in clamping jaws by means of displaceable parts 67.

Abstract: An acidic aqueous cleaner, preferably in emulsion or microemulsion form, which is of a pH in the range of one to four and is useful for cleaning hard surfaced items, such as bathtubs, sinks, tiles and porcelains, and even some such items which are not acid resistant, such as those of a European enamel known as zirconium white enamel, comprises synthetic organic detergent, such as a mixture of anionic and nonionic detergents, e.g., sodium paraffin sulfonate, higher fatty alcohol ethoxylate sulfate and higher fatty alcohol or phenol ethoxylate, organic acid, e.g., mixture of succinic, glutaric and adipic acids, phosphonic acid, e.g., aminotris-(methylenephosphonic acid) and phosphoric acid in an aqueous medium. 
     The acidic cleaner is useful to remove soap scum, lime scale and grease from surfaces of the mentioned items without adversely affecting such surfaces, and removals of the scum, scale and grease are easy, being effected by applying the micro­emulsion to the surface to be cleaned, followed by wiping it off. Although the cleaned surfaces may be rinsed that is often not necessary and the surfaces will be left clean and shiny after wiping, even without rinsing, or with minimal rinsing. 
     In the described emulsions the organic acid components effectively remove soap scum and lime scale, the detergents remove greasy soils and promote effective contact between the acid and the surfaces to be treated, and the combination of phosphoric and phosphonic acids prevents acidic attack by the organic acid(s) on the European enamel surface being cleaned.
