Patent number: 7962662Abstract: Unique addresses for a plurality of devices may be programmed through a single external connection (pin) on each device by using a one of a plurality of different analog voltage or current values on the single external pin in combination with a serial clock of a serial data bus for each device requiring a unique binary address. The unique binary address is stored in the device after detection of certain number of clocks on the serial data bus. Once the unique binary address has been stored in the device, the single external connection may be used for another purpose such as a multifunction external connection. This unique binary address may be retained by the device until a power-on-reset (POR) or general reset condition occurs. Address detection and address load commands on the serial bus may also perform the same address definition and storage functions.Type: GrantFiled: September 30, 2010Date of Patent: June 14, 2011Assignee: Microchip Technology IncorporatedInventors: Patrick K. Richards, Vincent Quiquempoix, Gabriele Bellini

Publication number: 20110093639Abstract: Encrypted encoding and decoding of identification data of CAN bus devices for communications therebetween provides deterrence of theft and unauthorized access of these secure CAN bus devices. Each one of the CAN bus devices is considered a “node” on the CAN bus for communications purposes. By using a unique encryption code stored in each of the “authorized” CAN bus devices, unauthorized CAN bus nodes will not be able to communicate with the authorized, e.g., secure, CAN bus nodes functioning in a CAN system.Type: ApplicationFiled: October 19, 2009Publication date: April 21, 2011Applicant: MICROCHIP TECHNOLOGY INCORPORATEDInventor: Patrick K.

Patent number: 6979239Abstract: Slots or apertures are formed in the connector shroud of a T/R module in a plane perpendicular to the axis of the connector so as to allow plating solution to flow freely through the entire inner portion of the connector, particularly the rear portion, during fabrication of the T/R module. The slots are formed prior to the shroud being brazed on to the module substrate. By allowing plating solution to flow through the connector, the interior of the connector can be more thoroughly plated, thereby improving the yield of the assembly while reducing cost.Type: GrantFiled: June 30, 2004Date of Patent: December 27, 2005Assignee: Northrop Grumman CorporationInventors: Patrick K. Richard, Edward L. Rich, III, Kevin L. Ebersole, Angela J. Martin, Tapan K. Gupta, David W. Strack, John S. Fisher, III

Patent number: 6611430Abstract: A miniature, self-locking, spring action, microwave T/R module retainer device includes a retainer body that holds a double arched spring and transfers the spring load to a coldplate. The double arched spring configuration is designed to contact an extended heat sink plate located on one side of the microwave T/R module. When in position, the deflection of the double arched spring of the retainer device imparts a force onto the extended heat sink, pressing the T/R module against the coldplate when the module retainer device is installed. If the position of the T/R module changes due to thermal or mechanical loads, the potential energy stored in the arched spring allows the spring to automatically re-adjust accordingly.Type: GrantFiled: September 4, 2002Date of Patent: August 26, 2003Assignee: Northrop Grumman CorporationInventors: Patrick K. Richard, Brian T. Drude, Hurley K. Blackwell, Lucinda G. Martin, H. Halley Lisle, David A. Herlihy

Patent number: 6278400Abstract: Two discrete transmit/receive (T/R) channels are implemented in a single common T/R module package having the capability of providing combined functions, control and power conditioning while utilizing a single multi-cavity, multi-layer substrate comprised of high or low temperature cofired ceramic layers. The ceramic layers have outer surfaces including respective metallization patterns of ground planes and stripline conductors as well as feedthroughs or vertical vias formed therein for providing three dimensional routing of both shielded RF and DC power and logic control signals so as to configure, among other things, a pair of RF manifold signal couplers which are embedded in the substrate and which transition to a multi-pin blind mate press-on RF connector assembly at the front end of the package.Type: GrantFiled: November 29, 1999Date of Patent: August 21, 2001Assignee: Northrop Grumman CorporationInventors: John W.

Patent number: 6097335Abstract: A transmit/receive (T/R) module adapted for use in a radar system. The module has a unified structure including a layered substrate on and in which two T/R channel circuits are integrated. The channel circuits make use of power distribution, channel controller, and RF signal routing circuitry, partly on a channel shared basis. In the RF routing circuitry, respective coupler elements are employed to combine RF receive signals for output to an RF receive manifold and to split an RF transmit signal from a transmit manifold into separate RF transmit signals for input to the T/R channel circuits.Type: GrantFiled: December 8, 1999Date of Patent: August 1, 2000Assignee: Northrop Grumman CorporationInventors: John W.
