Abstract: ABSTRACT    An armour component having a pair of layers of flexible high impact-resistant material with at least two juxtaposed layers of hard beads between the flexible layers.   The beads in the adjacent layers are disposed with beads thereof inter-nested in the inter-bead spaces of each other, and the volume occupied by the layers of beads is substantially void of all other material.         The beads of each layer may be arranged in a regular close-packed lattice pattern, i.e., a hexagonal or square so that each bead contacts its immediately adjacent neighbour beads.  The component is designed for flattening and trapping a bullet and when used as a body armour provides the outer part of the garment.  An inner component is used in the garment for spreading the impact of the bullet striking the outer part.  The inner component includes at least two layers of flexible material having at least one layer of compressible material confined therebetwen.  The garment using the outer part is light and flexible but is capable of trapping the bullet with little risk of spalling of the parts of the component.  The inner component, which is also light in weight as the compressible material may be a plurality of hollow fracturable plastic balls confined in compartments defined by tough plastic sheet material, is designed to soften and spread the impact on the body of the user to inhibit bruising or bone fracture.

Abstract: ABSTRACT    A front cover is provided with an open area to accom-modate visual displays, keyboards, switches, joy sticks and the like.  A back cover, nestingly interfitting therewith, is closed, but provided with a recess, encompassing most of its back area.  One or more identical nestingly interfitting intermediate frames may be nested and stacked between the back cover and the front cover to form a package of any desired volume.  The frames, back cover, and front cover are provided with means for mounting functional elements such as electrical circuit boards.  The front cover and intermediate frames are provided with peripheral circumferential ribs.          These ribs, and the slots therebetween, provide for a great variety of ways to mount the package, as does the rear re-cess in the back plate.  The front cover may be identical or nearly  identical to the  intermediate  frames.   Functional elements may be mounted to the covers  and  frames  during manufacture such that the covers and frames act as protec-tive  carriers  during  manufacture.   After  assembly,  they provide a closed package or case for the assembled unit.

Abstract: HIGH SPEED COUNTER      Abstract An M-bit binary counter is disclosed having M sequentially ascending binary value stages, the first stage being the lowest significant bit.  In accordance with the invention, each stage above the least significant bit stage has a subsequent value decoder which has the function of determining the effect of lower order carry bits on higher order stages with a minimum of signal delay.  The decoder includes the feature of using natural threshold FET devices in a transfer gate configuration to perform logical AND functions so as to minimize gate delays in decoding a carry condition for higher order stages.  A selective up-counting or down-counting function is also disclosed.

Abstract: Abstract A method and associated addressing circuit for storing the control code of a processor in a read only memory (ROM) and in a read/write memory RAM comprising a code area and a patch area.  It consists in virtually dividing the control code in blocks of n instructions, storing the first instruction of each block into the code area of the read/write memory, and storing the n-1 following instructions of each block in the read only memory ROM.  When an error is detected in at least one block, the first instruction of said block normally stored in the read/write RAM, is replaced by a branch instruction containing a branch address value so as to point to the patch area where the corrected block is stored.

Abstract: Abstract Apparatus and Method for Producing a Signal-To-Noise Ratio Figure of Merit for Digitally-Encoded-Data Apparatus and method for estimating a signal-to-noise ratio figure of merit of a received digitally-encoded binary sequence.  The data sequence originates from a source which transmits the data with transitions between logic states at the source occurring only at predetermined epoch time points.  The apparatus includes circuitry for producing transition signals whenever a transition is detected in the received data. Circuitry for generating reference signals from the received data indicative of the predetermined epoch time points of the transmitted data are also produced. The transition and reference signals are used to produce deviation data which represent the time difference between the transitions in the received data and the epoch time points.  Typically, the reference signals are used to allocate the transition signals into deviation data groupings in accordance with the time in which the transition occurs.  The deviation data groupings are then characterized to produce a figure of merit value.
