摘要:
A method for generating a plurality of moving objects on a video display screen in, for example, a video amusement game which utilizes a system of time shared hardware to provide for a change in position of the moving objects on the video screen. The method includes an object storage memory which may be updated during each vertical retrace interval and is scanned during each horizontal retrace interval to provide information for a horizontal memory which generates the next horizontal video display line. The horizontal memory contains an object identification code in the proper horizontal location and the actual video image is generated by an associated graphics generator and picture memory which respond to the object code.

Apparatus for producing a plurality of audio sound effects such as shots, explosions, and airplane and car sounds, used in electronic games utilizes a variable clock driving a variable digital noise generator whose audio output amplitude is shaped by either of two types of control units. In one type the density or duty cycle is varied by selectively ANDing together outputs from a polynomial counter. In a second embodiment a digital to analog converter utilizing gated resistive summing provides the amplitude control the gates being driven by a four bit data register which in turn is driven by the game control means.

A method and apparatus for generating moving objects for a video game display. Common apparatus including a microprocessor with RAM provides vertical motion for all objects and separate horizontal position counting hardware horizontal motion for each object. The microprocessor operating on a horizontal line pair basis drives a parallel to serial converter which stores one eight bit line portion of the object to be displayed which in turn is connected to a shift register. When the converted data is read out to the video display by action of the appropriate horizontal position hardware, it is recirculated to provide a repeat on the next horizontal line of the identical data. An effective one line moving resolution is obtained by utilizing another shift register for a one line delay by means of a switch which is set by a latch driven by the microprocessor.
摘要:
Apparatus for continuous variation of object size on a raster type video screen in a television game. The input of a voltage controlled oscillator is varied by a game controller. The output of the oscillator drives horizontal and vertical counters at rates corresponding to the object size. These counters provide respectively horizontal and vertical addresses to a picture generator read only memory. The faster the counters are incremented the smaller the object; and with regard to the vertical address, horizontal lines of the picture are actually skipped in order to reduce the size of the object.

A construction set is made up of a plurality of detachably chainable links capable of being pivotally attached to one another to form stable geometric structures. Detents are provided at a plurality of pivot positions so as to preferentially hold the engaged links in stable and precise positions relative one to another.

A three-dimensional ultrasonic position control device suitable for controlling computer displays or robot movements is disclosed.More specifically, signals from an ultrasonic transmitter are received by multiple receivers. The received signals are processed by a processing circuit which provides signals to a computer system for use in controlling a computer display or a robot. This system is particularly adapted to use inexpensive components to provide for a low cost mass producible control device.

A voice emulation device, operation of which is initiated by a person's voice, is disclosed. The device includes detector circuitry that responds to a voice to produce a binary indication of the voice that is delayed by a serial shift register. The delayed binary indication is coupled to a digital-to-analog converter where the rising and falling edges of the binary indication are "shaved" to provide the delayed binary indication with attack and decay characteristics to form an amplitude envelope. The amplitude envelope is modulated by a modulation signal of a pseudo-randomly varying (audio) frequency to generate an output signal which, when converted to aural form, produces a pseudo-articulate sound (i.e., voice emulation).

A pinball machine having a main body with a circular upper margin and a conical playing surface extending downwardly from said upper margin and inwardly toward the center of the body. The body has a ball-actuating plunger and curved track near said upper margin so that a ball can be propelled in a circular path along said upper margin and away from the track so that the ball can follow a spiral path and strike one or more targets as it moves over the surface toward the lower extremity thereof. A bumper is mounted on the body near the lower extremity of the conical surface, and the bumper has a shiftable element which is manually actuated by a push-button switch to cause an outward force to be exerted on a ball as the ball approaches the bumper near the lower extremity of the conical surface. The element applies a force to the ball in a certain direction to cause the ball to move upwardly on the conical surface and to strike one or more targets on the conical surface. A display means coupled with the targets receives and displays numerical or other scores associated with the striking of the targets. The body has a return hole and passage near the lower extremity of the surface.

A flexible flag has a plurality of spiral shaped wire elements carried by the flexible flag body. The wire elements are mounted for rotation about generally parallel axes along a vertical support. Gearing between a motor and the elements rotates the elements. The elements have portions spaced from their end portions offset from the axes of rotation. Those elements are in phase or out of phase relative to one another. Rotation of the elements causes a rippling or waving effect in the flag simulative of a flag waving in the breeze.

A broadcast and reception system provides a segmented broadcast signal for providing regional traffic information and a receiver adapted to receive selected segments of that broadcast. The segmented broadcast signal includes a number of segments which each include a tone sequence, a digital regional code, a digital duration code, and an audio segment. The receiver monitors selected regional traffic segments and converts the selected audio segment to a form compatible with a standard automotive radio. Thus, a user can selectively monitor regional traffic information without having to listen to reports from regions of no interest to him. Alternatively, the selected traffic information can automatically override normal radio listening.
