TL;DR: In this paper, a digital-imaging based system for reading graphical indicia, including code symbols, on objects such as, but not limited to, code symbol menus by the user simply pointing his or her finger at the particular code symbol on the code symbol menu to be read, while digital images of the coded symbol menu and the pointing finger are automatically captured, buffered and processed.
Abstract: A digital-imaging based system for and method of reading graphical indicia, including code symbols, on objects such as, but not limited to, code symbol menus by the user simply pointing his or her finger at the particular code symbol on the code symbol menu to be read, while digital images of the code symbol menu and the pointing finger are automatically captured, buffered and processed.
TL;DR: In this article, a method and system for reading code symbols using a code symbol reading system having a programmable decode time-window filter mode of operation is presented, where only decoded code symbols that have been scanned within a selected (eg central) portion of the laser scan line field are processed according to a special decode timewindow filtering function.
Abstract: A method and system for reading code symbols using a code symbol reading system having a programmable decode time-window filter mode of operation During this mode of operation, only decoded code symbols that have been scanned within a selected (eg central) portion of the laser scan line field are processed according to a special decode time-window filtering function In particular, if the decoded bar code symbol is a programming-type bar code symbol, then the system controller applies the function represented by the programming-type bar code symbol; and if the decoded bar code symbol is a non-programming-type bar code symbol, then the system controller either transmits symbol character data associated therewith to the host system or stores the symbol character data within memory aboard the bar code symbol reading system
TL;DR: The PECAN family of program development systems is designed to make effective use of powerful personal machines with high-resolution graphics displays and is currently implemented on APOLLO workstations.
Abstract: This paper describes the PECAN family of program development systems. PECAN supports multiple views of the user's program. The views can be representations of the program or of the corresponding semantics. The primary program view is a syntax-directed editor. The current semantic views include expression trees, data type diagrams, flow graphs, and the symbol table. PECAN is designed to make effective use of powerful personal machines with high-resolution graphics displays and is currently implemented on APOLLO workstations.

TL;DR: In this paper, a breakpoint address is determined at run time, advantageously after the specified object is created in accordance with execution of the program, and the defined action is performed only in response to determining that the firing occurred on the specified objects.
Abstract: A method used by a digital computer in controlling execution of an object-oriented program to effect a defined action, e.g., stopping the program, when a specified virtual function is invoked on a specified object during execution of the program. A breakpoint address is determined at run time, advantageously after the specified object is created in accordance with execution of the program. The breakpoint address determination is not based solely on symbol table, pre-execution, information, but in addition on information generated in conjunction with the creation of the specified object. The breakpoint is inserted while program execution is stopped at an intermediate program point after the specified object is created. After program execution is resumed and the specified virtual function is invoked in accordance with the program, the breakpoint fires. However, the defined action is performed only in response to determining that the firing occurred on the specified object.
