US Patent:

51778564, Jan 12, 1993

Filed:

May 9, 1991

Appl. No.:

7/697443

Inventors:

Steven A. Rogers - Leesburg VA
George Bockelmann - Vienna VA
Gary Hester - Sterling VA

Assignee:

Cryptec, Inc. - VA

International Classification:

B23P 1304

US Classification:

29557

Abstract:

An improved shielding assembly for a circuit board. This assembly is formed by providing a substantially flat piece of metal that will be used to form a shield assembly. A template is obtained indicating locations of folds and tabs. The folds are at locations that will enable the tabs to be located in the holes on the circuit board. The template is used to etch grooves and to etch tabs. This can be used to form a shielding assembly.

Steven Rogers - Leesburg VA
John Gerig - Reston VA

Assignee:

Objective Communications, Inc. - Portsmouth NH

International Classification:

H04N 710

US Classification:

348 6

Abstract:

An apparatus and method is provided for modulating and transmitting full-motion, television-quality color video signals along with digital data signals over a pair of ordinary unshielded twisted pair telephone wires without interfering with normal telephone data on the wires. A transmission method is disclosed involving frequency modulation of a baseband video signal and subsequent filtering to suppress an upper sideband corresponding to a color component of the original video signal. The filtered signal is received from the telephone wires at a difference location, filtered, demodulated and provided to a display device. Full-duplex operation over the same pair of wires is possible, such that two video signals may be simultaneously transmitted, each signal having an approximate bandwidth of 6 MHZ and shifted to a desirable noninterfering frequency location within the approximately 20 MHZ of usable bandwidth on the telephone wires. No pre-emphasis or de-emphasis is required to achieve good quality video transmission. The system has many applications including video distribution, conferencing, and communications.

Steven A. Rogers - Leesburg VA
George Bockelmann - Vienna VA
Gary Hester - Sterling VA

Assignee:

Cryptec, Inc. - Herndon VA

International Classification:

H05K 900

US Classification:

361424

Abstract:

An improved shielding assembly for a circuit board. The assembly includes a multi-layer circuit board, each layer of which has ground planes around the perimeter thereof. An edge plating on the circuit board connects the ground planes to one another. A number of tab holes are also in the board, and the shielding assembly is formed as a conductive box which is connected to the tab holes. A shielded area is formed within the shielding assembly. The shielding assembly is preferably formed by etching fold locations and folding, and by etching tabs to be formed.

US Classification:

346 76PH

Abstract:

A shielded print head assembly has a plurality of pieces that are self-aligned with one another. A base forms a ground plane, and includes a registry structure thereon which is preferably a pin extending above a top surface thereof. A circuit board is aligned by connecting inner surfaces of the circuit board around the pin to precisely locate a connector of the circuit board. A print head is located adjacent to the circuit board such that its connector is exactly adjacent to connector of the circuit board. An innerface connector is then used to connect between the circuit board connector and the print head connector, the interface connector being completely shielded by a cover. The interface connector is also held in self-alignment by the registry structure. The interface connector also has a top surface defining an insulation area, coupled against the cover which forms a ground plane. In this way, a shielded and self-aligned multi-piece print head is formed.

International Classification:

H04L 9/40
G06N 5/02
H04L 41/16

Abstract:

In some variations, first and second rule sets may be received by a network protection device. The first and second rule sets may be preprocessed. The network protection device may be configured to process packets in accordance with the first rule set. Packets may be received by the network protection device. A first portion of the packets may be processed in accordance with the first rule set. The network protection device may be reconfigured to process packets in accordance with the second rule set. A second portion of the packets may be processed in accordance with the second rule set.

Inventors:

- Portsmouth NH, US
Steven Rogers - Leesburg VA, US

International Classification:

H04L 9/40
H04L 47/11

Abstract:

Packets may be received by a packet security gateway. Responsive to a determination that an overload condition has occurred in one or more networks associated with the packet security gateway, a first group of packet filtering rules may be applied to at least some of the packets. Applying the first group of packet filtering rules may include allowing at least a first portion of the packets to continue toward their respective destinations. Responsive to a determination that the overload condition has been mitigated, a second group of packet filtering rules may be applied to at least some of the packets. Applying the second group of packet filtering rules may include allowing at least a second portion of the packets to continue toward their respective destinations.
