    Inline voice commands in word processor

    Invoking a command in a word processor typically involves a break in the flow of writing. For example, if a user wants to insert a table into a document that she is editing, she has to execute an operation such as pressing a key combination, performing a mouse movement, or a gesture to invoke a command. Such breaks in flow causes a loss of productivity. Further, performing such movements may be difficult for users with motor disabilities. This disclosure describes techniques that enable a user to issue voice commands without a break in the flow of writing

    Software Implemented Fault-Tolerant (SIFT) user's guide

    Get PDF
    Program development for a Software Implemented Fault Tolerant (SIFT) computer system is accomplished in the NASA LaRC AIRLAB facility using a DEC VAX-11 to interface with eight Bendix BDX 930 flight control processors. The interface software which provides this SIFT program development capability was developed by AIRLAB personnel. This technical memorandum describes the application and design of this software in detail, and is intended to assist both the user in performance of SIFT research and the systems programmer responsible for maintaining and/or upgrading the SIFT programming environment

    The Design and Implementation of the RPC Device Drivers

    The RPC project group is investigating high performance communication network interface structures which are compatible with existing operating systems, in this instance SunOS 4.1 Unix. The use of parallel processing in the marshalling and unmarshalling of RPC arguments together with direct I/O to and from the user's data area and early scheduling of user processes, are expected to give a higher throughput than more traditional implementations. The network front end comprises PC based TRAM's. The Unix machine is a Sun SPARC1+ running SunOS 4.1.3. The interconnection between the two systems is by the SCSI bus. To implement this structure requires a kernel device driver to act as a bridge between the Unix environment on the SPARC station and the TRAM's in the PC. This report describes the structure and implementation of this device driver, showing the design adopted to provide multiple rpc interfaces over a single SCSI bus
