High Gain Relay Antenna System With Multiple Passive Reflect Arrays

US Patent:
2022024, Aug 4, 2022
Filed:
Apr 12, 2022
Appl. No.:
17/719313
Inventors:
- Carlsbad CA, US
Jun Fang - San Jose CA, US
International Classification:
H01Q 3/46
H01Q 15/14
H04B 7/145
Abstract:
Examples disclosed herein relate to a dual-relay antenna system that includes a first passive reflect array configured to receive electromagnetic radiation from a transmitting source and generate a transmit beamforming signal with a first gain from the electromagnetic radiation. The high gain relay antenna system also includes a second passive reflect array positioned at a predetermined distance from the first passive reflect array and configured to collimate phases of the transmit beamforming signal from the first passive reflect array and transmit an outbound beamforming signal with a second gain greater than the first gain, to a coverage area. Other examples disclosed herein relate to a dual-reflect array system and a method of high gain relay with multiple passive reflect array antennas.

H04B 7/005
H04B 7/185
Abstract:
Examples disclosed herein relate to a communication system including a transceiver module, a rearrangeable switch network coupled to the transceiver module, a power distribution network coupled to the rearrangeable switch network, and a plurality of Beam Steering Phase Array (“BSPA”) antennas, each coupled to the power distribution network and dynamically controllable to generate beams according to a power regulation requirement for a set of sat/lies.

System And Method For Training A Neural Network Under Performance And Hardware Constraints

US Patent:
2023010, Apr 6, 2023
Filed:
May 6, 2022
Appl. No.:
17/738931
Inventors:
- Suwon-si, KR
Jun FANG - Santa Clara CA, US
David Philip Lloyd THORSLEY - Morgan Hill CA, US
Joseph H. HASSOUN - Los Gatos CA, US
Hamzah Ahmed Ali ABDELAZIZ - San Jose CA, US
International Classification:
G06N 3/08
Abstract:
A system and method for training a neural network. In some embodiments the method includes training a full-sized network and a plurality of sub-networks, the training including performing a plurality of iterations of supervised co-training, the performing of each iteration including co-training the full-sized network and a subset of the sub-networks.

Method For Sparsification Of Feature Maps In Self-Attention Mechanisms

US Patent:
2023002, Jan 26, 2023
Filed:
Sep 14, 2021
Appl. No.:
17/475330
Inventors:
- Suwon-si, KR
Joseph H. HASSOUN - Los Gatos CA, US
Jun FANG - Santa Clara CA, US
Chengyao SHEN - San Jose CA, US
International Classification:
G06N 3/08
H03M 7/40
H03M 7/30
Abstract:
A method is disclosed to reduce computation in a self-attention deep-learning model. A feature-map regularization term is added to a loss function while training the self-attention model. At least one low-magnitude feature is removed from at least one feature map of the self-attention model during inference. Weights of the self-attention model are quantized after the self-attention model has been trained. Adding the feature-map regularization term reduces activation values of feature maps, and removing the at least one low-magnitude feature from at least one feature map may be performed by setting the low-magnitude feature to be equal to zero based on the low-magnitude feature having a value that is less than a predetermined threshold. Feature maps of the self-attention model quantized and compressed.

Virtual Beam Steering Using Mimo Radar

US Patent:
2021038, Dec 9, 2021
Filed:
Aug 16, 2021
Appl. No.:
17/403657
Inventors:
- Carlsbad CA, US
Jun FANG - San Jose CA, US
International Classification:
H04B 7/0426
H04B 7/0456
H04B 7/08
Abstract:
Examples disclosed herein relate to a Multiple-Input Multiple-Output (MIMO) radar for virtual beam steering.
