TL;DR: In this article, a method for generating a plurality of moving objects on a video display screen in a video amusement game was proposed, which utilizes a system of time shared hardware to provide for a change in position of the moving objects in the video screen.
Abstract: 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.

TL;DR: In this article, an array of photosensitive imaging sensors connected to a digital computer is utilized to measure selected dimensions of objects upon which the photosensitive array is focused, and two sets of information in the form of analog signals generated by the sensors are converted to digital form and stored in a memory.
Abstract: An array of photosensitive imaging sensors connected to a digital computer is utilized to measure selected dimensions of objects upon which the photosensitive array is focused. Two sets of information in the form of analog signals generated by the photosensitive array, both with and without an object in view, are converted to digital form and stored in a memory. The two sets of information contained in the memory are compared to thereby create digital signals indicative of the dimensions of the object. These digital signals are converted to dimensional form and displayed.

TL;DR: In this article, an object identification system using an RF roll-call technique was proposed, where an interrogator illuminates a multitude of cooperating objects with a sequence of codes and receives from each such cooperating object an acknowledge signal immediately following the transmission of the code associated with that object and which terminates prior to completion of transmission of a next code in the sequence.

TL;DR: Hemsley as discussed by the authors reported a lack of significant relationships between measures derived from a choice reaction time task and the number of non-A responses produced on Payne's object classification test within a group of acute schizophrenics.
Abstract: DEAR SIR, In a recentarticle (Hemsley,1976)I reported a lackof significant relationships betweenmeasures derived from a choice reaction time task and the number of non-A responses produced on Payne's object classification test (Payne, 1962) within a group of acute schizophrenics. It was there suggested that scores on the latter are influenced by †̃¿ responsive ness' and that this would tend to blur any such relationships. A subsequent analysis is consistent with this interpretation. Instead of employing the total of non-A responses as thescoreon Payne'stest, the ratio of non-A to total responses was calculated; this method was used by Phillips et al (1965). A correla tional analysis indicates significant correlations between this measure and two of those derived from the choice reaction time task, response decision time (Rn)(r= +o .@6,P <0.05),andsusceptibility to distraction(D) (r = +0 P473, P < 0.05). The findings are therefore consistent with the suggestion that scores on the object classification test reflect both information processing deficits, as originally put forward by Payne et al @ and †̃¿ responsiveness', the latter being reduced in chronic patients. It is of interest that although the total of non-A responses of chronicschizophrenics tendto fallwithinthe normalrange,theratiofnon-Atototal responses exceeds all other psychiatric groups except acute schizophrenics (Payne, 1971).

TL;DR: A system of PL/I procedures has been written that permits geometric objects to be described hierarchically by effectively intercepting subprogram calls, providing a means of modifying the semantics associated with any object without modifying the object's procedural description.
Abstract: A system of PL/I procedures has been written that permits geometric objects to be described hierarchically. The objects are themselves represented as PL/I procedures, allowing very general use of variables. By effectively intercepting subprogram calls, the system provides a means of modifying the semantics associated with any object without modifying the object's procedural description.

TL;DR: In this article, the authors compare areas of a high-resolution object image with corresponding areas of low-resolution master pattern to produce signals representing the quality of the object, and determine whether these two features are the same.
Abstract: Successive areas of a high-resolution object image are compared with corresponding areas of a low-resolution master pattern to produce signals representing the quality of the object. Comparison is effected by detecting which of a set of features occurs in each area of the object image, detecting which feature of the same set occurs in a larger area of the master pattern, and determining whether these two features are the same.

TL;DR: A collection of program transformations and a model of the compilation process in terms of source-to-source transformations are presented, and a description of the application of these ideas to an existing programming language is given.
Abstract: We treat a program as an object of manipulation, determine items of program constancy, and simplify the program based on the constancy. Some motivation for program manipulation is presented, along with two examples of “higher level optimization” written in an Algol-like language. A collection of program transformations and a model of the compilation process in terms of source-to-source transformations are presented. Finally a description of the application of these ideas to an existing programming language is given.

TL;DR: The BGRAF2 language for interactive real-time 2D graphics was designed as a user-oriented language emphasizing ease of use rather than of implementation, and procedural statements allow straightforward computation while classlike characteristics encourage modular graphics programming.
Abstract: The BGRAF2 language for interactive real-time 2D graphics was designed as a user-oriented language emphasizing ease of use rather than of implementation. Procedural statements allow straightforward computation while classlike characteristics encourage modular graphics programming. The clock and event data types facilitate creation of parallel and synchronous procedures automatically acting on structures and display files. A graphic procedure, which includes procedural, drawing and event-driven statements, is a graphic prototype. Such procedures may be nested and iteratively or recursively called. An individual invocation of a procedure, called a graphic object, shares code while commanding its own data structures and images.

TL;DR: TOMAL is a new microprocessor programming language that has been designed to support process control applications and supports device-independent I/O programming, by allowing the characteristics of each external device to be given in a declaration.
Abstract: This paper describes the multi-tasking capabilities of a new microprocessor programming language that has been designed to support process control applications. A program in TOMAL is a collection of tasks, priority ordered, and possibly having real-time response constraints and internal synchronization statements. It also supports device-independent I/O programming, by allowing the characteristics of each external device to be given in a declaration. A TOMAL source program is translated into space-optimized, absolute code for a target microprocessor. The object program runs under the control of a compact, application-tailored Task Control Monitor that is also generated by the compiler. The paper discusses design philosophy and several important requirements of an implementation to achieve multi-tasking capabilities.

TL;DR: In this paper, an optical system for strip scanning of an object in both directions of relative reciprocal motion between the object and the optical system is presented, where the object is first scanned in one direction, then the optical axis between object and image is effectively rotated 180° for scanning in the reverse direction.
Abstract: An optical system for strip scanning of an object in both directions of relative reciprocal motion between the object and the optical system. The object is first scanned in one direction, then the optical axis between object and image is effectively rotated 180° for scanning in the reverse direction. Properly oriented images are thus projected onto a photoreceptor during both directions of scan.

TL;DR: Whereas the treatment here is not complete, the template concept introduced in the model does suggest a useful framework for providing the much talked of but seldom realized benefits of data extensibility.
Abstract: A model for storage in procedural languages is presented. Its fundamental notion is to strictly distinguish values from storage objects. Several difficulties in current languages are resolved in this model, e.g., the problem of flexible locations [1] and the meaning of the term type [2, 3, 4]. In the light of the storage object/value dichotomy, several notions are found to be covered by the term type. The implications of the model are explored with respect to the more conventional data constructs of procedural languages as well as to sets and how they might be provided. Finally, data extension mechanisms are considered. Whereas the treatment here is not complete, the template concept introduced in the model does suggest a useful framework for providing the much talked of but seldom realized benefits of data extensibility.
