Patent number: 4908746Abstract: A control system (10) controls transfer of electronic signals to and from industrial and scientific equipment. The control system includes a real-time database (60) for storing data elements which may be accessed by a plurality of tasks (62, 64, 66, 68, 70, and 72). Each data element in the real-time database (60) has an associated changed status flag for each task which indicates whether the value of the element has changed since the last access by the task. Individual tasks must communicate through the real-time database, since no inter-task communication is supported. The tasks support bidirectional communication with industrial and scientific equipment, alarm supervision, data logging, real-time clock functions, mathematical and logical functions, and interactive operator communications.Type: GrantFiled: October 15, 1986Date of Patent: March 13, 1990Assignee: United States Data CorporationInventor: Mitchell D.

Patent number: 4901308Abstract: A time slot interchange matrix is comprised of a plurality of matrix modules (50-56) each for receiving data on a plurality of channels and transmitting data on the same number of channels. Each of the modules consists of separate banks of random access memory that are interfaced with an intramatrix bus (70) for receiving data from each of the matrix modules in the system for storage therein during a collection frame. During a transmission frame, this information is randomly accessed in accordance with an interconnect pattern stored in a control RAM (122) for output from the digital matrix module. Each digital matrix module stores all of the information in the system such that the system is non-blocking for any given channel stored such that information is not impeded by the interconnect pattern of another digital matrix module. A digital bridge (80) is provided for collecting the information during a collection frame and then accumulating the information in a bridge IC circuit (137) as a conference.Type: GrantFiled: April 25, 1989Date of Patent: February 13, 1990Assignee: DSC Communications CorporationInventor: Stephen A.

Patent number: 4890254Abstract: In a communications system (10), data is transferred from a physical interface section (64) and two processors, a receive processor (66) and a transmit processor (68). The data is transferred from the physical interface (64) to the receive processor (66) through a receive fifo (112). Data is transferred from the transmit processor (68) to the physical interface (64) through a transmit fifo (110). To prevent the transmit processor (68) and the receive processor (66) from processing data faster than the physical interface (64), clock disabling circuits (1030 and 1032) are utilized wherein the system clock (1033) to the receive processor (66) will be disabled when both the receive fifo (112) is empty and the current instruction performs a read from the receive fifo (112). The system clock (1050) to the transmit processor (68) will be disabled when both the transmit fifo (110) is full and the current instruction executes a write to the transmit fifo.Type: GrantFiled: July 21, 1989Date of Patent: December 26, 1989Assignee: Aristacom International, Inc.Inventor: Bradford S.

Patent number: 4890317Abstract: A telephone system and method of operation are disclosed which use a microprocessor control system (10), a speech generator (34) and speech memory (46) to interact with a calling party placing a long distance phone call. The telephone receives a billing account number from the calling party thorugh a keypad (24). The telephone determines the validity of the billing account number by attempting to place a telephone call using the billing account number to a controlled telephone number. If the attempt is successful the billing account number is valid and a communication path is established through a telephone line interface (38). The microprocessor controlled system (10) generates a billing record for the call which is stored in a call record memory (11). The billing record can later be retrieved to facilitate billing the call.Type: GrantFiled: January 23, 1989Date of Patent: December 26, 1989Assignee: Intellicall, Inc.Inventors: John A. Hird, Lindsey D. Owen, Michael R. Rice

Patent number: 4884137Abstract: A video system is disclosed having a weapon-mounted video camera (12) transmitting video signals to a remotely located video display (14). The video display is mounted to the helmet (40) of a soldier (36), and includes a sight reticle (50) superimposed on the image of the target (46) so that the soldier (36) can aim the weapon (38) by moving it until the target object (46) as displayed by the video display (14) is aligned with the sight reticle (50).
