Process Control System With Improved Fault Isolation
US Patent:
4527271, Jul 2, 1985
Filed:
Aug 17, 1982
Appl. No.:
6/408967
Inventors:
Donald O. Hallee - North Easton MA
Harold Lake - Sharon MA
Kenneth L. Johansson - North Grafton MA

International Classification:
G06F 922, G06F 1100
US Classification:
371 20
Abstract:
A process control system includes redundant digital controllers and a plurality of input/output (I/O) modules for interfacing with remote field sensors and actuators. Bi-directional communication between controllers and I/O modules is achieved by a parallel-wired, process I/O bus. Failures within the system, including the bus structure itself, that continually keep the bus active (i. e. , in a low state) are isolated by a combination of software diagnostic routines for performing bus checkout and a unique quick disconnect feature that readily isolates the fault condition first between the I/O module nest area and the controllers, then, if necessary, to individual I/O modules. During fault isolation procedures, individual I/O modules may be disconnected from the bus while the values of field signals are simultaneously maintained to provide minimum process upset.

Appl. No.:

International Classification:
E05B 65/10
US Classification:
292093000
Abstract:
Access control is a technology that allows remote locking and unlocking of doors. The information to cause these systems to function is usually derived from keypads, magnetic cards, proximity cards, motion detectors, manually activated switches and time schedules read by a computer. Many of the locking devices on the doors selected for access control are manually activated only. In order to implement an access control system, these devices must be made to activate electrically by some means. The common method to do this is to replace this very good and durable hardware with new hardware that has electric activation incorporated into it. This is a very expensive method to gain the functionality needed. Other methods are also used but the result often compromises security and the locking system integrity. This invention is a new approach to gaining the desired functionality, without compromising the safety, security and locking integrity of the door and lock system. This invention meets the need but at a much more reasonable cost. It is equipment that is added to the existing door hardware.

International Classification:
B42F 13/00
US Classification:
402079000
Abstract:
Described is an improvement to a loose-leaf binder, also known as a loose-leaf notebook, to facilitate moving the covers and pages from an open position to a closed position without the intervention of special closing techniques. With the system created with this invention, the binder covers are simply closed.
