Abstract: A method and system for providing the ability to add or remove components of a data processing system without powering the system down ("Hot-plug"). The system includes an arbiter, residing within a Host Bridge, Control & Power logic, and a plurality of in-line switch modules coupled to a bus. Each of the in-line switch modules provide isolation for load(s) connected thereto. The Host Bridge in combination with the Control & Power Logic implement the Hot-plug operations such as ramping up and down of the power to a selected slot, and activating the appropriate in-line switches for communication from/to a load (target/controlling master).

Abstract: ERASE THROUGH TAB An electronic typewriter which has the capability of erasing characters automatically and which has the further improved capability of being able to back through unused space on the line, which results after a tabulation command, thereby allowing the repositioning of the type element over the characters typed prior to the tab command thereby allowing automatic erasure of those characters. The improvement of the typewriter as described permits the retrieving of characters from an electronic memory and the use of that memory to control the erase cycle even where the carrier position and the character to be erased are on opposite sides of space without printed characters due to a tab command. This is accomplished by the electronic control of the mechanical hardware and the ability to determine where the tab command was entered on the typing line and to prevent erasure cycles in the unprinted space until the carrier has returned to the point at which the tabulation command was entered.

Abstract: On electronic typewriters which have the ability to record into a small working memory those characters, functions and escapements which are keyed at the keyboard, it is many times advantageous to be able to place the carrier and the print point over a character which has been previously typed without using repeated backspaces. Disclosed herein is a feature for an electronic typewriter which permits the operator to easily align the print point with a character on the page by positioning a reference mark on the card holder or print carrier in relation to a previously printed character and then through keyboard control cause the carriage to shift its position such that the print point is then exactly aligned with the character printed. The positioning of the carrier such that the reference mark is in relation to the desired print point is accomplished by a backspace operation and the repositioning or causing of the carrier to assume a position immediately over the subject character is accomplished by keyboard control through the electronics of the typewriter to cause the carrier to shift a predetermined distance.

Abstract: A contact type thermal sensing apparatus for a hot roll fusing unit includes a fail-safe detector to insure intimate contact between the thermal transducer and the monitored roll surface. The fail-safe detector also insures intimate contact between an over temperature sensing device and the monitored roll surface. The thermal transducer includes a thermally and electrically conductive contact which is held against the surface of the rotating conductive fuser roll. The output of the transducer is utilized to control the amount of heat supplied to the roll. A second thermally and electrically conductive contact is held against the surface of the rotating conductive roll and includes a thermal fuse which prevents further heat application to the roll should the surface thereof become overheated. The fail-safe detector comprises an electrical continuity circuit which includes the two contacts and the conductive roll. If either of the contacts becomes separated from the roll, electrical continuity therebetween is broken and the detector output prevents further heat application to the roll. The fail-safe detector thus insures that the transducer and thermal fuse contacts are intimately contacting the roll thereby preventing excessive overheating of the roll occasioned by the loss of such contact.

Abstract: UNDERSCORE ERASE of the Invention The electronic controls for a typewriter disclosed herein allow the operator to erase a character using automatic erase capability such as disclosed in U. S. Patent 3,780,846 and at the same time to remove any underscores associated with that character. When an underscore command is entered the memory which stores the code representing the characters typed is caused to be altered in its content to indicate upon the reading of that code segment that the character has been underscored and that the character must be erased along with the underscore. The apparatus accomplishes multiple erase cycles to remove the underscore and then the character. In proportional space mode of operation it is possible that multiple underscore erase cycles will be necessary to remove an underscore which is wider than the underscore type font on the type element.

Abstract: PARAGRAPH INDENT of the Invention Described herein is a feature and the electronics and logic necessary to implement a paragraph indent feature on an electronic typewriter which is improved and more advantageous than previous routines which accomplished similar results. Paragraph Indent is beneficial to the operator in that it automatically positions the printing carrier at an indented level for setting off typed material so that the left edge of the indented material does not extend to the normal left margin. The typewriter under electronic control stores in memory, upon an appropriate command, a temporary left margin to which the carrier will return when the typewriter is operating under the paragraph indent mode. The operator may enter the Paragraph Indent mode from the keyboard by keying an alternate or code together with a tabulation or tab code. This causes the electronics to control the typewriter so as to move the print point to the next tab stop and thereafter until countercommanded will return the carrier to that indented line position on all subsequent carrier returns.
