Abstract

Methods and apparatus for discovering codeword decoding order in a serial interference cancellation receiver using reinforcement learning. In an embodiment, a method is provided for decoding codewords in a multiple-input-multiple-output (MIMO) communication network. The method includes determining a decoding order based on a state space and a decoding policy, decoding selected codewords based on the decoding order, updating the decoding policy based on the decoding results and the state space, updating the state space based on decoding results, and updating the decoding order based on the state space and the decoding policy.

Abstract

The present inventive concept consists of a logic controlled submersion brewing device that operates reliably with minimal user interaction. The brewer employs a submersion brewing technique to ensure a uniform extraction of beverage from solid extraction media. The device may be programmable to start on a timer. Parameters of the brew program may be customizable including serving size and extraction settings. The device will use vapor pressure to forcibly move beverage liquid across a sieve thereby separating the liquid from spent extraction media. Reliability and repeatability of the separation procedure is enhanced using a novel method of pressure control.

Abstract

An integrated circuit for controlling operation of a motor of a fan assembly. The fan assembly includes a housing and a fan. The motor is in the housing. The housing is void of sensors. The motor is configured to rotate the fan. The integrated circuit includes a detection module and a first control module. The detection module is separate from the fan assembly. The detection module is configured to detect a voltage induced in a first coil of the motor or a back electromotive force received from the first coil of the motor. The first control module is configured to receive a control signal from a second control module and control the operation of the fan based on (a) the control signal, and (b) the voltage induced in the first coil of the motor or the back electromotive force. The second control module is separate from the integrated circuit.
