Abstract: A frequency demodulation circuit disclosed superposes pulses on an input frequency-modulated (FM) signal at substantially peaks of the FM signal before demodulating the FM signal so that zero cross points of the FM signal can be correctly restored. A peak detection circuit detects peaks of the FM signal or peaks of the fundamental wave of the FM signal, which substantially correspond to the peaks of the FM signal. A pulse generating circuit generates, from the peak detection result, a train of pulses respectively occurring at the same timings as those of the detected peak occurrance timings. The generated train of pulses and the FM signal are respectively fed to differential inputs of a differential input type limiter. An output signal of the limiter is fed to a pulse count circuit to obtain a frequency demodulated signal.

Abstract: A boundary representation solid modelling system is described that enables building of a solid-model through a trial-and-error approach. The result of a non-manifold union set operation on a geometric model is used to update a non-manifold boundary representation date file. Correspondence between elements in the boundary representation file and primitives is retained in another store. This allows elements of a non-manifold boundary representation, originating from a primitive, to be identified when the primitive is specified, and vice-versa. A history of set operations is also stored. Reworking of a set operation is achieved by selecting a primitive to delete, accessing and deleting corresponding elements from the boundary representation file and modifying the set operation history file. The invention thus enables cancellation of reworking of a set operation independently of its order. Hence, or a set operation executed at any given time can be rapidly reworked.

Abstract: A liquid crystal display provides a high quality color image and efficient energy utilization. A layer of liquid crystal material (24) is controlled by a transparent electrode matrix (2). A matrix (20) of (primary color emitting) phosphors, each in alignment with a transparent electrode, is fixed to a surface of a fiber optic plate (18). A source of fluorescent energy excites the phosphors. A filter (14) located behind the fiber optica plate reflects visible light, both ambient and that emitted from the phosphors. The fiber optic plate (18) acts as a relay lens and prevents cross pixel color contamination while the generation of backlight by the phosphor conversion of fluorescent to visible energy is a highly efficient process.

Abstract: A two- or three-dimensional geometric modeling method and an apparatus therefor in which a two- or three-dimensional shape is input to a processing unit via an input unit to form a shape, the formed shape is extracted from the processing unit and displayed on a display unit, data for changing is input to the processing unit from the input unit in order to change the displayed shape or scale, and the shape or scale is changed on the basis of predetermined stored information, thereby displaying the changed shape or scale on the display unit. The predetermined stored information is stored as a history such that a plot method and plot contents of each of plot operations executed upon formation of the shape and an order of the plot operations correspond to a geometric constraint for defining the shape to be formed. When a portion to be changed of the shape or scale is specified, the history is referred to search a plot operation forming the specified portion to be changed. Instead of inputting adding information for this changing, the searched plot operation is executed in accordance with the data to be changed to execute changing (cancelling, adding, and correction) of the shape or scale.

Abstract: An electrical test probe comprises an outer barrel (10) and a plunger (18) extending axially through the barrel (10) and having an outer portion extending through an open end (12) of the barrel (10) and terminating in a contact tip outside the barrel (10) for contact with a test point (44). The plunger (18) is supported within the barrel (10) by spring pressure for allowing spring biased relative axial motion between the plunger (18) and the barrel (10). The plunger (18) is rotatable about its axis during relative axial motion between the plunger (18) and barrel (10) against the bias of the spring (20) so that rotation of the plunger (18) causes enhanced contact between the probe and a test point on a circuit board under test. The contact tip comprises a head (40) having a substantially continuous outer blade edge (52) extending around a periphery of the head (40) and positioned thereon to engage the test point (44) on the board (46), and at least one further substantially continuous inner blade edge (54) inside the outer blade edge (52) and positioned preferably concentrically with respect to the outer blade edge (52) also for contact with the test point (44) on the board (46). The inner and outer blade edges (52,54) are able to spin about the axis of the plunger (18) during their contact with the test point (44) without causing the plunger (18) to bind in the barrel (10) as the head (40) is rotated during contact with an irregularly shaped test point (44) on the board (46).
