Abstract: A method for judging the correctness or incorrectness of a prospective contour point of an irradiation field comprises the steps of, on a line which connects a predetermined point 1.cated in the region inside of an irradiation field on the recording medium with an edge of the recording medium, detecting prospective contour points, each of which is considered to be an intersection of the line and a contour of the irradiation field, on the basis of the image signal components corresponding to the picture elements arrayed along the line, detecting a change point of the image signal components arrayed along the line, which change point arises characteristically only in the region inside of the irradiation field, and in cases where the change point has been detected, judging that a prospective contour point located on the predetermined point side of the change point is not present on the contour of the irradiation field and is thus incorrect. Alternatively, after detecting prospective contour points, the method includes the steps of calculating a characteristic value of the image signal components corresponding to the picture elements arrayed along a single line or along each of a plurality of lines, each of which line extends from the prospective contour point to the direction that goes away from the predetermined point, comparing the characteristic value with a predetermined value, and based on the results of the comparison of the characteristic value with the predetermined value, judging whether or not the prospective contour point is truly present on the contour of the irradiation field.

Abstract: In a mechanism (2) for transporting a tape cartridge or cassette, a gripper arm (28) carries two spaced projections (22, 24) that engage one surface of the cartridge. A gripper finger (28), formed of material with sufficient flexibility that any accidental external forces applied to the cartridge will result in release of the cartridge without damage to the case, engages the opposite surface of the cartridge, between the two projections (22, 24). The gripper finger (28) itself moves first in a rotary path to position the gripper finger (28) adjacent one edge of the cartridge and secondly is translated in a direction perpendicular to the surface of the cartridge to be clamped. 
     The rotary movement of the gripper finger (28) is produced by rotary movement of a flexural beam while the translation is produced by a collar (34) having a cam (46) that impinges on a smooth surface to detect the collar (34) and the gripper finger (28) upwardly to secure the cartridge. The toggle action of the cam (46) eliminates the need for continued external forces to maintain the cartridge in clamped condition. A lost-motion arrangement permits limited rotation of the flexural beam to move the gripper finger (28) into and out of engagement with the cartridge surface without causing any translation of the gripper finger (28).

Abstract: A description is given of a motor drive circuit (9) for driving an electromotor (7) with a permanent magnet rotor and a stator comprising one or more stator windings (25, 26, 27). When the supply voltage of the motor drive circuit (9) fails, an emergency signal is generated by a signal generator (36). 
     This emergency control signal activates an auxiliary power supply circuit for extracting electric energy from the motor and supplying the extracted energy to an auxiliary circuit (8). The auxiliary power supply circuit comprises a rectifier circuit formed by the fly back diodes (25c, 25d, 26c, 26d, 27c, 27d) bridging the switches (25a, 25b, 26a, 26b, 27a, 27b) of an electronic commutation circuit. The drive circuit comprises short-circuit switches (25e, 26e, 27e) bridging the stator windings (25, 26, 27). In response to the emergency control signal a short-circuit means (37) causes the stator windings (25, 26, 27) to be temporarily intermittently short-circuited. As a result, a capacitor (32) is charged. The energy stored in the capacitor (32) is used for temporarily feeding an auxiliary circuit (8) once the power supply to the drive circuit has failed. If the drive circuit is used in combination with a hard disc drive, the energy supplied by the auxiliary power supply circuit can be used for moving the magnetic head (3) to an idle position.

Abstract: The invention relates to an ignition mechanism for a pyrotechnic gas generator (18) of an occupant restraint system for vehicles, in which a striking element (26) for triggering the tautening operation is pretensioned by at least one spring (56), in such a way that the spring (56) loads the striking element (26) in a first direction against a stop. Furthermore, as a result of the inertia forces taking effect during an acceleration of the vehicle, the spring (56) counteracts the movement of the striking element (26) in a second direction with a force increasing until a dead centre is reached. The spring (56) at the same time generates a torque which is converted by a transmission device (58) into an axial force loading the striking element (26). <IMAGE>

Abstract: A control system for pipelined image processing emulates a multi-tasking environment using a single tasking application. A number of predefined image processing tasks are provided in a library. When a host application (120) needs a processed image from an image source (12), the host application creates a pipeline (40) of initialized instantiations of one or more of the tasks from the library. When the host application invokes the pipeline, the first data request for the header of the image travels upstream in a first channel (42). The processed image header is returned down the first channel. Then a data request for scanlines of image data is sent upstream in a second data channel. The data request ripples upstreamwardly to the upstream-most instantiation of one of the tasks (1,2,3) from the task library. The upstream-most instantiation of a task obtains a scan line from an image data source and returns it downstreamwardly to the host application (120) in the second channel. Each instantiation of a task from the task library further operates on the image data. Once all of the scanlines have been processed, the memory allocations and data structures (44) created during initialization are released to free up that memory.
