Abstract: Portable tester and method for testing a variety of circuit boards without utilizing adaptor boards for re-routing input test signals and supply voltage from the tester to pins of the board under test. A plurality of edge adaptors having different pin spacings have their respective pins connected in parallel to corresponding edge connector stake pins. Each edge connector stake pin is connected to or isolated from the corresponding driver/sensor stake pin by means of a switch. Each driver/sensor stake pin is connected to the input/output terminal of a programmable driver/sensor circuit. A plurality of power supply stake pins are connected to various power supplies of the portable tester. Connectors coupled to the family board can be utilized to route power supply voltages to electrically isolated edge connector stake pins. Isolated driver/sensor outputs can be routed to other edge connector stake pins. A main processor stores a test program and transmits data and control information to predetermined driver/sensor circuits. A high speed processor is coupled between the main processor and the inputs of the driver/sensor circuits. The high speed processor memory can store a bus-defining subroutine containing a sequence of data shifting instructions which shift a word in the shift register to the input of specified driver/sensor circuits at high speed. The high speed processor can synchronize the operation of the portable tester with an asynchronously operating printed circuit board under test.

Abstract: The display device comprises a cell having two levels, between two polarizers 1 and 7, the directions of polarization of which are at an angle of 120 DEG  to each other. The two-level cell comprises two liquid crystal layers 5 and 6, each of which, in the rest condition, causes rotation of the plane of polarization of the light through 60 DEG . The orientation of the molecules of the input surface of the first layer 5 is parallel to the direction of polarization P1 of the first polarizer 1. The orientation of the molecules of the input surface of the second layer 6 is parallel to the orientation of the molecules on the output face of the first layer 5. The orientation of the molecules of the output surface of the second layer 6 is parallel to the direction of polarization P2 of the second polarizer 7. This construction provides a two-level cell which is clear if the two liquid crystal layers are both in the rest condition, and which is dark in all other situations, whether one or the other or both layers 5, 6 are energized.
