Filed:

Nov 17, 1997

Appl. No.:

08/972159

Assignee:

International Classification:

H04J 314

US Classification:

370248, 370380

Abstract:

A system and method for electronically identifying connections established through a cross-connect system provides for the identification of all hard-wired and temporary patch connections, and any modifications made to existing cross-connect circuit connections. Connection identification and status information is acquired in near real-time and stored in a database which is accessible by a user through a graphical user interface (GUI). The TRACE or lamp wires which connect respective pairs of cross-connect circuits are utilized in an unconventional manner so as to form a scanning bus. The information signal paths established through the cross-connect circuits remain undisturbed. A scanning signal is communicated between each pair of cross-connected circuits over the TRACE conductor. In the event a patch cord is used to temporarily redirect a signal connection, the scanning signal is transmitted over the shield or sleeve conductor of the patch cord. The scanning signal provides identification and other information concerning the transmitting circuit.

International Classification:

H04N 7173

US Classification:

725119, 725116, 725138, 725146, 725148

Abstract:

A switch apparatus is used in the transmission of a redundant Cable TV (CTV) signal. The redundant CTV signal can be a symmetric split linked redundant CTV signal or an asymmetric split linked redundant CTV signal. The switch apparatus is capable of handling both the symmetric and asymmetric redundant CTV signal where primary channels are split into multiple parts. The asymmetrical splitting of the primary channels is where one part contains more channels than another part. The switch apparatus includes a plurality of switches and a monitor device to detect a failure in the split signal path before the split signals are combined to be transmitted to downstream end-users. Upon detecting a failure, the switches are switched from primary channels to secondary channels by a controller. After the signal is returned, the switches are switched back to the primary channels. A delay timer may be included in the switch apparatus to avoid incidental or temporary signal recovery.

Inventors:

Yevsey Gutman - Minneapolis MN, US
John Joseph Keller - Anoka MN, US

Assignee:

Gnath Tech Dental Systems, LLC - Anoka MN

International Classification:

A61C 19/04

US Classification:

433 69, 433 54, 433 57, 433 68, 433229

Abstract:

An apparatus to replicate and analyze movement of a mandible relative to a maxilla with dental casts thereof includes a base frame, an arm connected to the base frame and a suspension assembly positionable by a plurality of electro-mechanical actuators. The arm connects to the base frame and supports the dental cast of the maxilla in a fixed position relative to the base frame. The suspension assembly, having opposing first and second sides, supports the dental cast of the mandible in working relation to the dental cast of the maxilla. The plurality of actuators each selectively impart movement to the sides of the suspension assembly such that the movement of the mandible obtained during a recording process can be replicated on the apparatus in real time.

Abstract:

An apparatus for use in dentistry to obtain positional data related to movement of a mandible about a maxilla comprises a rigid support frame for supporting a maxilla support member, a positionable mandibular member and sensing assemblies. The support member fixedly attaches to the support frame. The mandibular member is positionable proximate the maxilla member. The sensing assemblies attach to the support frame and connect to the mandibular member to obtain positional data related to the movement of the mandibular member. The positional data is collected by a computing device and stored in a data storage medium as time history files. The files can then be transformed into usable information to replicate the mandibular movement in real time either virtually or mechanically.
