  • Publication number: 20210050030
    Abstract: A system may perform speech enhancement of audio data in real-time by suppressing noise components that are present in the audio data while preserving speech components. The system may include an in-ear module and a separate signal processing module that is wirelessly communicatively coupled to the in-ear module. The system may include non-negative matrix factorization (NMF) dictionaries capable of identifying frequency band components associated with speech and frequency band components associated with noise. The NMF dictionaries may be trained using voice samples and noise samples. The NMF dictionaries may be applied to noisy speech data to produce an NMF representation of the speech data which may then be applied using a dynamic mask to the noisy speech data in order to suppress the noise components of the noisy speech data and produce speech enhanced data.

  • Publication number: 20200275706
    Abstract: A cartomizer of an electronic vaping device includes a heater circuit which is located adjacent an air passage thereof. The heater circuit includes an electrically resistive heater in electrical communication with a secondary coil. A wick extends across the air passage. The wick is configured to draw pre-vapor formulation from a reservoir toward the heater. The heater is configured to heat the pre-vapor formulation to a temperature sufficient to vaporize the pre-vapor formulation and form a vapor. The cartomizer is connectable to a power supply component which includes a power source in electrical communication with a primary coil. The power supply component is configured to induce sufficient voltage in the secondary coil of the heater circuit such that the secondary coil is configured to heat the heater and vaporize the pre-vapor formulation when the primary coil is powered by the power source.

  • Patent number: 10753717
    Abstract: Among other things, a digitally controlled actuator has a connector for coupling to a drive mechanism of an existing hand-driven cartridge reloader, to actuate a series of processing cycles of the reloader in which supplies of components are subjected to successive mechanical processing steps to produce reloaded cartridges ready for use. There are sensors associated with the actuator and the reloader to (a) acquire digital information that is indicative of a state of progress of each of the processing cycles and of conditions of the reloader related to the production of the reloaded cartridges, and (b) deliver the digital information to a digital controller for controlling the processing cycles of the reloader. The digital controller is connected to receive the digital information from the sensors and to control automatic operation of the reloader in successive processing cycles to produce reloaded cartridges without requiring human intervention.

  • Patent number: 10736018
    Abstract: The present application provides a near field information transmission method and system, an information transmitting client, an information receiving client, and an information system. The information transmitting client transmits an acquisition request to the information system. The information transmitting client receives a random number that corresponds to the acquisition request and is returned by the information system. The random number corresponds to the information of said information transmitting client. The information transmitting client uses the random number as a service set identifier of a hotspot, and the service set identifier is broadcast through a beacon frame of a wireless communication protocol. The present techniques conduct near field information transmission conveniently and accurately.

  • Patent number: 10713540
    Abstract: A system and method is provided that utilizes deep learning, including convolutional neural networks, to identify subject objects in unconstrained user images such as unknown pills. An image of, e.g., a pill, may be captured and subsequently processed using deep learning models to identify the pill. The deep learning models may be optimized to have a small footprint (in terms of computational and memory resources) suitable for a resource-limited device such as a smartphone while retaining a high object recognition accuracy. Each such model may also be run on modified versions of the unconstrained image, for example on color, greyscale, and gradient images, to focus the models on different distinguishing features of the object.
