Patent number: 5956045Abstract: A coordinate input system to which control data (a displacement value), concerning the location and the posture of a displayed graphic object, can be input with a conventional coordinate pointing device, such as a mouse, and a method therefor. Coordinate values of three sequential input points P.sub.n, P.sub.n+1 and P.sub.n+2, which are entered with a coordinate pointing device, such as a mouse, are employed to calculate the central angle .angle.P.sub.n O.sub.n P.sub.n+2 relative to the arc P.sub.n P.sub.n+1 P.sub.n+2 of the circle O.sub.n circumscribed about these three points. Then, the angle .angle.P.sub.n O.sub.n P.sub.n+2 is employed to acquire the central angle .angle..theta..sub.n for the arc P.sub.n P.sub.n+1. A logic circuit or an upper-level program that waits for the input of the dial rotation value as control data employs the central angle .angle..theta..sub.n, which is acquired by inputting the coordinate values of the two sequential points P.sub.n and P.sub.Type: GrantFiled: October 22, 1996Date of Patent: September 21, 1999Assignee: International Business Machines CorporationInventors: Kazuhiro Gotoh, Seida Iida

Patent number: 5923898Abstract: A memory controller having request queue and snoop tables is provided for functioning with bus interface units interposed between a multiple processor bus and individually coupled to the respective processors in a complex incorporating a multitude of processors, where each bus interface unit includes block snoop control registers responsive to signals from a system memory controller including enhanced function supportive of I/O devices with and without block snooping compatibility. The tables are compared to minimize and more efficiently institute snoop operations as a function of the presence or absence of the same listings in the tables. The BIU provides functionality for the bus of the multiple processors to be processor independent. This architecture reduces the number of snoop cycles which must access the processor bus, thereby effectively increasing the available processor bus bandwidth. This in turn effectively increases overall system performance.Type: GrantFiled: May 14, 1997Date of Patent: July 13, 1999Assignee: International Business Machines CorporationInventors: Thomas B. Genduso, Wan L. Leung

Patent number: 5905486Abstract: The present invention contemplates a display generating system, preferably a computer such as a mobile client system, in which text entry to supply data for a defined field in a form or the like is facilitated. In particular, the present invention contemplates combining certain functions heretofore separated in a display which accepts data entry such as letters or numbers entered by hand using a stylus or the like. In a system implementing this invention, the functions of providing a cursor which indicates the location for data entry and providing a field displaying or receiving data entry are combined. By this combination, the field receiving or displaying an entry is positioned immediately adjacent the displayed field for such entry, permitting a user to focus attention on a single location in the display as distinguished from dividing attention between a location at which a cursor prompts for data to appear and a separated field at which the entry is entered or displayed.Type: GrantFiled: March 3, 1997Date of Patent: May 18, 1999Assignee: International Business Machines CorporationInventors: Peter James Brittenham, Liam David Comerford
