IPC: G06F3/0488
Filed: 1992-04-28
Abstract: The invention provides for a method of capturing the coordinates of a handwritten signature and compressing the coordinate data so obtained. The signature is captured in real time by a device such as a stylus-operated digitizer (206,208) and compression is performed by examining the location of signature points (l05,ll8) relative to a series of guide lines (99,ll3) extending in the strokewise direction i.e. the direction taken by the device during writing of the signature. Only the data representing signature points (l05,ll8) satisfying a predetermined requirement relative to the guide line (99,ll3) is stored so that the signature data is stored in compressed form for use in subsequent transactions requiring authorization by the signature which has been so captured.

Abstract: A bulb holding structure according to the invention includes a pair of spring fixing members 11 and a projection 12 having a spring holding claw 14. The spring fixing members 11 and the projection 12 are disposed on the back side of a reflector 1 and located opposite to each other with respect to a bulb 8 inserted in a hole of the reflector 1. A spring catching concavity 13 is made in the outer face 12b of the projection 12. The outer face 12 is exposed in a direction opposite to the members 11. The spring catching concavity 13 is formed U-shaped by a pair of side grooves 13a, 13b elongated in a direction in which a push portion 10c of a spring 10 is pressed and a groove 13c linking the side grooves 13a, 13b with each other. The other ends of the side grooves 13a, 13b are open toward the push portion 10c. The claw 14 is given in the concavity 13 by excavating the projection 12 as mentioned above. The projection 12 is further provided with an inclined guide face 14b for catching the spring 10 and an inclined guide face 15 for releasing the spring from the claw 14. The releasing guide face 15 is inclined so that a portion 10b' of the spring 10 to be held by the claw 14 is disengaged from the claw 14 and guided along the guide face 15 by pressing the push portion 10c. The catching guide face 14b is inclined in the same direction as the releasing guide face 15.

Abstract: Disclosed is a termination circuit having a wide range of stable operation and a low power consumption. Conventionally, current flows in a termination when the signal in the transmission is not changing, which is wasteful of power. Attempts have been made to solve this by using circuits where no current flows through the termination when the signal in the transmission line does not change. However because of the characteristics of the circuits used, instability occurs during the transition from one state to the other state. The termination disclosed overcomes this by having complementary inverters having differing input/output characteristics.

Abstract: A compilation mechanism generates a simulation model of a logic system comprising a plurality of design units connected together in a network. The compilation mechanism is controlled by a steering file comprising a set of statements. Each statement specifies whether a design unit is to be expanded as a sub-network, represented in terms of its behaviour specification, or both concurrently expanded as a sub-network and represented in terms of its behaviour specification. A CHECK command compares outputs from the sub-network and the behavioural simulation. A SUPPRESS command selectively inhibits checks on particular ports of the sub-network.

Abstract: In examining the progress of patients before and after a cataract operation, all data can be computed upon the morphology of cornea endothelium cells for use of medical treatment, from a cornea endothelium cell image with less labor. 
     Positional data of center points of two-dimensionally continuous cells of a cornea endothelium cell image are entered into a computer. Center points of the cells within a specified distance from a given center point are sorted clockwise (101-104). If an angle formed by two angularly successive points and the center point is less than a specified angle, the point having the greater distance from the center point is excluded (105-113). If the distance between the first point and the third point of three angularly successive points is shorter than the distance between the given center point and the second point, the second point is excluded (114-122). In this way, for each given cell a set of peripheral points which are center points of cells directly adjacent to the given cells is obtained. The average distances between the peripheral points and the center point of each given cell are determined (123). A perpendicular line that proportionally divides the distance between a center point and any of its peripheral points proportional to the ratio of their average distances to the peripheral points is determined, and intersection points of the resulting perpendicular lines are determined as vertices of the polygonal outline of the cells (124-131). Thus, morphological data are computed from the obtained vertices (132).

Abstract: A plurality of the areas of different light reflectivity of a bar code symbol, or the like, are simultaneously illuminated, using, e.g., a beam of laser light that has an elongated cross-section. The laser light beam is swept over the symbol in a direction transverse to the elongated dimension of the illuminated region so that a two-dimensional area of the symbol is illuminated over time, until the symbol is read. The light that reflects from the illuminated region of the symbol is imaged on a linear sensor array, which is then scanned or read out to produce signals representative of spatial intensity variations of the imaged light along a linear path in the field of view.
