Abstract: A motor assembly is provided including a stator and a rotor. The stator includes a stator main body defining a longitudinal axis, stator teeth projecting radially from the stator main body, stator windings wound around the stator teeth, and two winding terminals provided for each stator tooth extending away from the stator main body substantially parallel to the longitudinal axis. A circuit board is oriented along a radial plane adjacent the stator. The circuit board includes a central through-hole through which a rotor shaft extends, at least one magnetic sensor mounted on a surface of the circuit board around the central through-hole configured to magnetically interface with the rotor, peripheral openings arranged to receive the winding terminals of the stator, and conductive routings extending from the peripheral openings to connect the stator windings in a series or a parallel configuration and/or a wye or a delta configuration.

Abstract: An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

Abstract: Techniques for providing an artificial intelligence denoiser related to audio processing are discussed herein. Some embodiments may include providing an audio signal sample associated with at least one microphone to a time-frequency domain transformation pipeline for a transformation period. Some embodiments may include providing the audio signal sample to a deep neural network (DNN) processing loop that is configured to determine a denoiser mask associated with a noise prediction for the audio signal sample. In a circumstance where the denoiser mask is determined prior to expiration of the transformation period, some embodiments may include applying the denoiser mask associated with the noise prediction to a frequency domain version of the audio signal sample associated with the time-frequency domain transformation pipeline to generate a denoised audio signal sample associated with the at least one microphone.

Abstract: A motor assembly is provided with a stator including a lamination stack forming a stator core, stator teeth inwardly projecting from the stator core, and stator windings wound around the stator teeth in connected in phases. A rotor is rotatably disposed within the stator with a shaft, a rotor lamination stack mounted on the shaft, and at least one bearing mounted on the shaft. An external heat sink is provided including a main body defining a hollow opening form-fittingly receiving the stator therein in thermal communication with the stator. A bearing support structure is provided having a main body radially arranged and secured the main body of the external heat sink, the bearing support structure forming a central bearing pocket arranged to receive and support the bearing of the rotor therein to axially and radially support the rotor with respect to the heat sink.

Abstract: A lawn mower comprising a frame supported on rotatable wheels for movement over a ground surface; an operator support coupled to the frame and configured to support the entire weight of an operator of the lawn mower during use thereof; a blade assembly comprising one or more blades that are configured to cut grass on the ground surface; a steering system configured to manipulate the steering direction of the wheels; a motor assembly configured to: drive the wheels so as to move the frame along the ground surface; and a first rechargeable battery module removably coupled to the frame and configured to power the motor assembly.

Abstract: A lawn mower includes a frame, an operator support, a blade assembly, a steering system, a motor assembly, a sensor and one or more processors. The operator support is coupled to the frame and is configured to support the entire weight of an operator of the lawn mower during use thereof. The motor assembly is configured to: drive rotatable wheels so as to move the frame along the ground surface; and drive at least one blade relative to the ground surface to cut grass. The sensor is configured to detect the presence of a person or an animal in a predetermined area proximate the lawn mower. The one or more processors are configured to: receive input from the sensor, and control the motor assembly stop driving the at least one blade, the wheels, or both based on the input from the sensor.

Abstract: A container and method for cooling beverages to an acceptable consumption temperature and then for maintaining that beverage temperature for a sufficient time so as to allow the beverage to be consumed is provided. The container includes a beverage chamber for receiving a beverage therein which is defined by an open top, a lid for reversibly sealing the open top, and a beverage chamber side wall. The beverage chamber side wall has an inner wall, an outer wall and a bottom portion. A reservoir side wall is disposed surroundingly at a spaced relationship to the beverage chamber side wall so as to define a reservoir therebetween. A phase change material is disposed in the reservoir.

Abstract: The present invention provides an insulated container for cooling hot beverages to an acceptable temperature and then maintaining the beverage temperature in an acceptable temperature range for consumption. This invention has an upper reservoir and a lower reservoir surrounding a beverage chamber, the upper and lower reservoirs communicating with one another through at least one passageway having a two-way valve. A liquid located in the lower reservoir is permitted to flow into the upper reservoir through the valve. The thermal liquid removes some of the heat from the hot beverage. After the hot beverage reaches a satisfactory drinking temperature, the liquid is then allowed to flow back through the valve into the lower reservoir. The air in the upper reservoir maintains the beverage at a proper temperature. A method of use is also provided.
