Abstract: The invention relates to an improved electric kaleidoscope which uses an electric motor to provide a continuous, smooth turning operation to the end cap assembly of the kaleidoscope, thus eliminating the tiring, awkward and jerky manual turning of kaleidoscopes. The main tube of the kaleidoscope has a housing that contains the electric motor, switch and wiring to power and turning of the end cap assembly. The end cap assembly of the kaleidoscope is removeable as is the end cap assembly cover of the end cap assembly, thus providing an easy means of changing the various colors and shapes of viewing objects in the object space of the end cap assembly. The removeable end cap assembly cover, which can be screw-on, snap-on or push-on type, allows the operator to change the end cap lens by inserting a clear lens to view the immediate surroundings in a kaleidoscopic display, or inserting a somewhat opaque lens and view objects in the object space to view an infinite variety of internally generated images or designs.

Abstract: A camera shutter system has a motor driven sector for opening and closing a shutter opening. A photo-interruptor is positioned to intercept a light beam, to effect the generation of a photo-interruptor signal. A timer has a counter that is set to a first count in response to the photo-interruptor signal, and is reset when a given count is reached. A shutter malfunction signal is generated when the level of the photo-interruptor signal has not changed by the time the given count is reached.

Abstract: A camera shutter system has a motor driven sector for opening and closing a shutter opening. A photo-interruptor is positioned to intercept a light beam, to effect the sequential generation of first and second photo-interruptor signal pulses, the first pulse having a width that is a function of the speed of the sector. A timer has a counter that is set to a first count corresponding to an exposure value that is a function of the brightness of an object to be photographed and the width of the first photo-interruptor signal. The timer is controlled to count down in response to the second photo-interruptor signal, and the sector driving motor is energized during the count down of the timer.

Abstract: A camera crane has a two-arm boom supported in swivel fashion by a support olumn whose height can be adjusted. Swivel-mounted to the first arm is a platform for a camera and, if so desired, a seat for a camera-man, and swivel-mounted to the second arm is a cage to receive balance weights. A parallel-guide apparatus provides for the parallel guidance of the platform and the cage when the boom is rotated. In order to provide a greater hoist area, the boom--whose first arm of length "a" supporting the platform in standard operation is longer than the second arm of length "b" supporting the cage in standard operation--is provided with an extension piece of length "c" serving to lengthen the second arm. The cage can be replaced at the end of the second boom arm, lengthened with the extension piece, by the platform, and the cage can be attached in place of the platform at the end of the first boom arm.

Abstract: A camera system including a camera and a data back has recording, display, and control functions. Signals are exchanged between CPU's of the camera and the data back through interface circuits. In one embodiment, the data back delivers periodic shutter release commands to the camera in an interval mode of operation so that the shutter is released cyclically. A shutter release signal causes an exposure operation, the completion of which terminates the shutter release signal. Then the shutter release signal is generated again to cause another exposure operation. If shutter release is not completed within a predetermined period, a new cycle of shutter release operation is nevertheless initiated.
