Title: Dual trace electro-optic display
Inventor: SHANKS IAN ALEXANDER
IPC: G01R13/00
Filed: 1981-06-22
Abstract: Two signal traces are displayed simultaneously on an electro optic display such as a liquid crystal display. The display may be in cartesian format having m X electrodes and n Y electrodes in which case the X electrodes are in strip form whilst each Y electrode comprises two or more interleaved components Ya, Yb. Thus each XY intersection may be addressed by a zero voltage at XYa, or XYb with above threshold voltages elsewhere. A series of m different coded waveforms are generated and applied a different one to each X electrode. The two traces are sampled and converted to digital sample values. Coded waveforms are generated and applied to each Ya Yb electrode contemporaneously with those applied to the X electrodes; the codes being generated are selected from the m different codes and relate to the position of the Y electrodes and the sample value to be displaced. The coded waveforms may be binary codes such as pseudo random codes. A priority encoder allocates a priority to sample values of the two trace signals.

Patent GB-813696-A (GB)
Abstract: 813,696. Electric battery lamps. GRUBENLAMPENWERKE VEB. Feb. 24, 1956, No. 5830/56. Class 39(2) [Also in Group XXXVI] A miner's electric headlamp set comprises an alkaline accumulator battery (see Group XXXVI), a headlamp comprising a reflector housing 2 containing a reflector, a lamp bulb holder 37, a lighting circuit switch 50, and conductor means aranged electrically to connect through said switch a lamp bulb, when in position in the holder, with the battery terminals. The housing 2 for the bulb 38 and reflector is preferably made of moulded synthetic material, and contains the bulb holder 37, Fig. 5, provided with a base flange 39 which seals off a presure-tight space 40 enclosing three resilient contacts 41, 42, 43 located in different planes due to their being in electrical contact with axially movable contact pins or rods 44, 45 and 46 respectively which are of different length, the outer ends of the said pins or rods being in abutment with corresponding contacts of a two filament bulb. The bulb is retained in the holder against the pressure of the resilient springs by means of a substantially U-shaped stirrup 47 which is slidable transversely to the axis of the holder within grooves positioned so that the arms of the stirrup bear downwardly upon the bayonet pins 49 of the lamp bulb, the pressure of the pins on the arms of the stirup serving also to hold the latter against the action of a compression spring 48. A rotary switch 50 mounted on the rear of the housing 2 and coaxial with the reflector comprises a cup-like contact-carrying member 51 fitting closely within the air-tight space 40 and an operating part 52 projecting outside the housing. A contact strip 53 within the rotary member 51 is connected permanently to lead-in a contact 54 connected to one conductor of the cable 3 and, by rotation of the member 51 may be contacted alternatively with a tongue 55 displaced angularly from the contact 42 or a similar tongue 56 on the contact 43 to connect one or the other of the bulb filaments in the battery circuit. The three contacts 41-43 being in held different planes by the contact pins are normally displaced from one another. If, however, the reflector housing is subjected to a mechanical or impact shock, the bulb, due to inertia, is moved further into the holder against the pressure of the contact springs, the stirrup 47 is withdrawn by its tensioned spring 48, and the bulb is ejected from the holder, thereby allowing the contact 41 to short-circuit the contacts 42 and 43; this blows a fuse in the battery casing.
