Title: Apparatus and method for providing an extended processing environment on nonmicrocoded data processing system
Inventor: CUTLER DAVID N
IPC: G06F17/16
Filed: 1988-06-30
Granted: 1992-06-02
Abstract: ABSTRACT    In a data processing system employing microcode techniques,  complex  sequences  of  microinstructions can  be  initiated  by  application  of  a  single macroinstruction.   These  complex  sequences  of microinstructions are typically noninterruptible and therefore  the  execution  of  a  macroinstruction  is atomic  (i.e.,  executed  as  a  single  entity).   Data processing  systems  that  do  not  employ  microcode typically have simpler macroinstruction sets that do not  provide  for  a  similar  atomicity  for  complex instruction sequences.  In order to obtain the same atomicity of instruction execution and to provide a nonmicrocoded  data  processing  system  with  the capability to execute complex instruction sequences as  an  atomic  operation,  the  nonmicrocoded  data processing system is provided with a third mode, in addition to  the  (nonprivileged)  user  mode  and  the (privileged) kernel mode, of operation that permits the  execution  of  instruction  sequences  with interrupting  events  disabled  and  certain  functions and  apparatus  enabled  to  faciliate  instruction sequence execution.

Abstract: SYSTEM BUS HAVING MULTIPLEXED COMMAND/ID AND DATA          ABSTRACT OF THE DISCLOSURE            A system bus    for an information processing system 10 includes a first group of signal lines    whereon command/ID information is time multiplexed with data, and a second group of signal lines   for conveying address information. During a first bus cycle command/ID information is presented on the first group of signal lines while the address is presented on the second group of signal lines. During a subsequent bus cycle, and for a data write or data return operation, the first group of signal lines conveys data. Other bus connections, such as cache memories, are thus apprised of the address a full bus cycle before the data is presented thereby providing the bus connections with sufficient time to decode and otherwise operate on the bus information. Multiple word data returns from a system memory are characterized as having the address associated with a particular word of data presented in the immediately prior bus cycle, facilitating the pipelining of data and address information through the system bus. The dual functionality of the first group of signal lines eliminates the requirement for separate and dedicated command/ID and data signal line paths and associated driving and receiving circuit elements.

Abstract: FAULT INDICATOR HAVING ELECTROSTATICALLY-ACTUATED INDICATOR FLAG               Edmund O. Schweitzer, Jr.                 Abstract of the Disclosure A fault indicator for indicating the occurrence of a fault current in a monitored conductor includes an electrostatically-actuated indicator assembly.  During normal operation a lightweight indicator flag rotatably mounted in and viewable from the exterior of the indicator housing is held in a reset-indicating position by electrostatic force resulting from an electric field existing between the flag and adjacent electrodes.  Upon occurrence of a fault current in the monitored conductor the electric field is removed and the indicator flag, under the influence of a permanent magnet, is caused to rotate to a fault-indicating position.          By avoiding the use of magnetic actuator windings and associated pole pieces the indicator assembly is easier and more economical to construct.

Granted: 1993-03-23
Abstract: ABSTRACT OF THE DISCLOSURE    A duplicate recording system uses video cassettes for storing master library recordings.  On both the recording and the duplicating ends of the system, all signals are buffer stored in an electronic memory while the signals are in a digital form.          This buffer storage completely isolates the recording/reproducing steps so that the usual parameter of restraints disappear.  For example, the duplication ratio may be any value within the capabilities of the recording/reproducing machines.  This isolation eliminates expensive setup procedures heretofore required to switch from one to another duplicating ratio.  The buffer storage also provides a more precise transfer with greater fidelity of the recorded signals.  A computer calculates a smoother analog curve when the digital-to-analog conversion is made.

Title: Commercial message timer
Inventor: JOHNSON GENE HARLOW
IPC: H04N5/45
Filed: 1989-09-28
Granted: 1992-07-28
Abstract: RCA 85,079 ABSTRACT A commercial message timer, when enabled by a user, stores data indicative of a first tuned station and begins timing a predetermined time period. Upon expiration of the time period, the first tuned station is automatically reselected if it had been deselected after the timer was enabled. In this way a user can avoid a commercial message on a first channel by setting the timer and scanning through other channels, and yet have the receiver return automatically to the first channel at the end of a time period substantially equal to that of a typical commercial message. In another embodiment employing PIX-IN-PIX circuity, the subject apparatus is responsive to the sequence of (1) enabling the timer and (2) changing channels for automatically moving the desired channel to the inset position. In response to the expiration of the timer period, the program displayed in the inset position is automatically r turned to the main display position.
