A display system using a matrix of rotatable display elements is provided in which the optical states of the display elements can be read back to confirm that the matrix is portraying information correctly. The display system is arranged to automatically ameliorate the effect of detected non-operating display elements on the intelligibility of the message displayed.

An information pad for checkbooks including a cover of a flexible foldable plasticized material, a plurality of sheets affixed together along a common edge, a backing layer affixed to the plurality of sheets and having a front side and a back side, and a hinge member affixed to the backing layer and extending outwardly beyond the common edge of the plurality of sheets. The hinge member is adhesively affixed to the cover. The cover is a checkbook cover. The hinge member has an adhesive strip exte...

The information carrier contains a code made up of a number of code signs including at least one recognition code sign. The information to be displayed is contained in a maximum of n-1 information code signs while a separating code between each two adjacent information code signs is of a value so that no more than n identical code signs can follow each other. The control and monitoring means are constructed to detect the succession of more than n identical code signs and separate out each possib...

An information storage system has a magnetic head transducer for reading and/or writing information on a flexible magnetic recording disc. The head has an upper recording/playback surface with a one inch radius of curvature along its major axis and a one half inch radius of curvature along its minor axis for providing optimum contact between the head and disc while at the same time minimizing wear. The head is affixed to a ramp member having an inclined surface sloping away from the upper record...

An animal ear tag is disclosed which comprises two components and a pin which connects the components to one another and attaches them to the ear of the animal. The tag is constructed so that it is possible to record, on the animal itself, as much information as the farmer requires about it. Projections which can be removed or left in place, edge depressions the remaining material of which can be cut out or left in place, two sets of digital bars and two depressions for receiving colored studs e...

An information processor and a method of information processing enables a write once type disc to be used as a rewritable recording medium. There can be realized an address control mechanism wherein even if the physical recording position is changed, the logical address of the same block is not changed by controlling the physical recording position on the recording medium on an imaginary address space in correspondence to the logical address. Thus the write once type recording medium can be real...

An apparatus for reading information from an information recording disc in which the information is recorded successively in the circumferential direction, which includes a timing signal generator for consecutively generating timing pulse signals at a rate proportional to the rotational speed of the recording disc. The apparatus repeats the jump-back operation during pause mode of operation in synchronism with the timing pulse signals.

An information buffer unit, comprising a random access store, for converting a received character sequence into a character sequence which is synchronous with an independent clock, for example, for use in digital telecommunication networks.

An information board includes display bands having information printed thereon mounted on wind-up rolls, the wind-up rolls being mounted on an axle. A wind-up motor is used to rotate the axle when the motor is rotated in a first direction to wind-up a display band, thereby changing the information shown on the display band. The information board further includes a mechanism which changes the rotational motion of the motor, when rotated in the opposite direction, to axial motion for moving the ax...

An information kiosk serving as an interactive information source for multiple users including users in wheelchairs. The information kiosk includes eight modular units which are connected to one another to form a ring of modular units. The information kiosk provides both visually displayed and printed information to several of users at the same time in response to user input. The information kiosk includes a plurality of modular units which each include a cabinet structure containing a CPU, a to...
