Thomas M. Hartnett - Nashua NH, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H01P 1/22
H01P 1/203
H03H 7/01

Abstract:

Methods and apparatus for a frequency selective limiter (FSL) having a magnetic material substrate that tapers in thickness and supports a transmission line that has segments and bends. The segments, which differ in width and are substantially parallel to each other, such that each segment traverses the substrate on a constant thickness of the substrate.

International Classification:

H02M 7/00
H01F 27/28
H01F 27/42
H03M 1/12
H02J 50/40

Abstract:

A modular high-power converter system includes an electronic power distribution unit configured to output an analog current (AC) voltage to a power bus, and at least one Transmit or Receive Integrated Microwave Module (T/RIMM) that includes a voltage converter unit and a transmitter and receiver (T/R) unit. The voltage converter unit includes at least one analog-to-digital converter (ADC) to convert the AC voltage into a direct current (DC) voltage having a first DC voltage level. The transmitter and receiver (T/R) unit includes a modular-based DC/DC converter to convert the DC voltage into a second DC voltage having a second voltage. The modular-based DC/DC converter includes a modular power converter unit configured to generate the second DC voltage. The modular converter unit is configured to be independently interchangeable with a different modular converter unit.

Appl. No.:

15/611138

Jason D. Adams - Medway MA, US

International Classification:

H05K 7/20
F28F 13/16
H01L 23/473

Abstract:

An apparatus includes a substrate and a matrix having multiple cells embedded within the substrate. The matrix is configured to generate electrostatic fields to define at least one flow path for liquid metal. The apparatus also includes a pump configured to create movement of the liquid metal through the at least one flow path defined by the matrix. The matrix is configured to transport the liquid metal through the at least one flow path in order to remove thermal energy from one or more areas of the substrate. The matrix could include a matrix of capacitors, and polarities of charges stored on the capacitors could define which cells allow passage of the liquid metal and which cells block or restrict passage of the liquid metal. The cells that block or restrict passage of the liquid metal could be configured to increase a viscosity of the liquid metal.
