Appl. No.:

D/047464

Inventors:

John C. McDaniel - Worcester MA

International Classification:

2101

US Classification:

D21133

US Patent:

46850570, Aug 4, 1987

Filed:

Jun 6, 1983

Appl. No.:

6/501205

Inventors:

Lou Lemone - Stow MA
Salvatore Faletra - Framingham MA
John R. McDaniel - Acton MA
Steve Caldara - Wayland MA

Assignee:

Data General Corporation - Westboro MA

International Classification:

G06F 1300

US Classification:

364200

Abstract:

The disclosure relates to a memory mapping system wherein information is stored on a page by page basis in memory in discontiguous locations therein with the address of the next page in which storage is to take place always being available in the controller to minimize delay in storage from the end of one page to the beginning of the following page, regardless of page location in memory. When a user makes a request for storage space in memory, the amount of memory required is determined and the host looks to see where it can obtain that memory. Typically, use of discontiguous memory locations is required. All of the information relative to the addresses of the discontiguous storage locations in memory is provided to the controller by the host computer in a single command rather than after each move to a discontiguous storage location. All jumps to discontiguous storage locations are then performed independent of the host computer.

International Classification:

G06F 1300

US Classification:

395325

Abstract:

A data processing system is disclosed in which a plurality of high performance, intelligent, mass storage input-output devices are linked to a host controller by an input-output interface bus which is divided into three sections. Each section is completely independent of the other two sections and used for a different and specific purpose. One section is used to transfer commands and retrieve status information. A second section is used to handle device requests for data transfer and device signals for operation complete. The third section is used to transfer data to and from a device. Since the three sections are completely independent, simultaneous transfer of command control and data to different input-output devices or to a single input-output device can be performed.

Assignee:

Data General Corporation - Westboro MA

International Classification:

G06F 930
G06F 1516

US Classification:

364200

Abstract:

A data processing system which includes a host processor and an input/output (I/O) controller unit for controlling communication with I/O devices. The controller processor receives I/O commands from the host processor, accesses and stores control block lists of control commands associated with such I/O commands, and executes the control commands from such control block lists. The controller unit stores controller information concerning the operational capability of the controller unit and the host processor is capable of accessing such controller information and in turn can modify such operational capability if desired.

Appl. No.:

14/618841

Inventors:

John C. McDaniel - Worcester MA, US
Anthony J. Paravano - Uxbridge MA, US

International Classification:

H01H 9/02
B65D 25/10

Abstract:

A protective cover is provided for a remote control device of the type having a plurality of buttons designed to be pressed to perform operations on a remote apparatus. The protective cover includes a rigid skin configured to be secured to the remote control to cover a front of the remote control. The rigid skin includes openings formed therein to selectively reveal certain buttons of the remote control device to be pressed by an operator of the remote control device. The rigid skin is configured to prevent covered buttons from being pressed by the operator.
