Patent ES-8206944-A1 (ES)
Title: Linear high gain sampling amplifier
IPC: H04N9/72
Filed: 1981-09-18
Abstract: A signal sampling circuit comprising a switch network coupled to a transconductance amplifier for providing output currents proportional to input voltage, an input clamp network, and a charge storage device is disclosed. The amplifier signal input is clamped to a reference potential via a negative current feedback path when the switch occupies a first position during nonsampling, clamping intervals. During subsequent sampling intervals, the switch occupies a second position for decoupling the feedback path and coupling the amplifier output to the storage device, so that the storage device then develops a sample of amplifier output signals, referenced to the clamping potential, as a function of amplifier output currents.

Title: Enhanced scattering in voltage sensitive encapsulted liquid crystal.
IPC: G02F1/1334
Filed: 1984-03-20
Abstract: Encapsulated liquid crystal material in a support medium illuminated from the viewing side or direction or though a louvred light guide from the back side will appear bright or white relative to background when in distorted alignment, e.g. in the absence of an electric field. Incident light impinging on the liquid crystal material is isotropically scattered into the support medium, and using the principle of total internal reflection and possibly also optical interference a relatively large part of the isotropically scattered light is directed back to illuminate the distorted liquid crystal material tending to brighten the same so that light it scatters back to the viewing direction out of the support medium causes the liquid crystal material to appear relatively light or bright as compared to the background where there is no liquid crystal material or where the liquid crystal material is in parallel alignment in field-on condition, i.e aligned with respect to an electric field, and, thus, substantially transmissive. Original incident light where there is no liquid crystal material, that light which is isotropically scattered toward the back or non-viewing side of the display and within a certain cone or solid angle, and that light passing through aligned (field-on) liquid crystal material will tend not to be totally internally reflected such light will pass through the support medium and may be absorbed by a remote black or colored material.
