  • Patent number: 11943735
    Abstract: An indoor target positioning method based on an improved convolutional neural network (CNN) model includes acquiring and preprocessing target camera serial interface (CSI) data of a to-be-positioned target and matching the preprocessed target CSI data with fingerprints in a positioning fingerprint database to obtain coordinate information of the to-be-positioned target. The generation method of the positioning fingerprint database includes: collecting indoor WiFi signals by a software defined radio (SDR) platform to obtain indoor CSI data corresponding to the WiFi signals, and preprocessing the indoor CSI data; partitioning the preprocessed indoor CSI data into a plurality of data subsets through a clustering algorithm; training an improved CNN model by the data subsets to obtain a trained improved CNN model; and generating the positioning fingerprint database by the trained improved CNN model and the preprocessed indoor CSI data.

  • Patent number: 11943578
    Abstract: A loudspeaker device comprising a loudspeaker unit comprising a diaphragm with a first and second surface (such as the front and rear surface of the diaphragm, respectively) and an enclosure in which the loudspeaker unit is mounted such that the first surface of the diaphragm is in acoustic communication with the surroundings of the loudspeaker device. The device further comprises an internal cavity formed in the enclosure and being in acoustic communication with the surroundings of the loudspeaker device via an acoustic element. In the device, the second surface of the diaphragm is in acoustic communication with the internal cavity. The acoustic element can be varied between a state in which sound energy generated by the loudspeaker unit in the internal cavity can be emitted to the surroundings via the acoustic element and a state in which sound energy is substantially prevented from entering the surroundings via the acoustic element.

  • Patent number: 11937056
    Abstract: A method of multi-talker separation using a 3-tuple coprime microphone array, including generating, by a subarray signal processing module, a respective subarray data set for each microphone subarray of the 3-tuple coprime microphone array based, at least in part, on an input acoustic signal comprising at least one speech signal. The input acoustic signal is captured by the 3-tuple coprime microphone array. The 3-tuple coprime microphone array includes three microphone subarrays. The method includes determining, by the subarray signal processing module, a point by point product of the three subarray data sets; and determining, by the subarray signal processing module, a cube root of the point by point product to yield an acoustic signal output data. The acoustic signal output data has an output amplitude and an output phase corresponding to an input amplitude and an input phase of a selected speech signal of the at least one speech signal.

  • Patent number: 11909919
    Abstract: An enhanced routing system determines a service provider best suited to fulfill a user's request to interact and establishes a communication session between the user's client device and a device of the service provider. The enhanced routing system may use user characteristics and behavior to select the service provider. For example, the enhanced routing system receives a request to connect to a customer service system from a user who has recently started a new job and has been accessing a banking application on his mobile phone. The enhanced routing system may determine that a payroll service provider is best suited to fulfill the user's request. For example, the enhanced routing system uses a machine learning model that has been trained on previously fulfilled requests. In this way, the enhanced routing system improves upon systems that continuously prompt the user for information by selecting a service provider without overburdening the user.

  • Patent number: 11902036
    Abstract: Systems and methods of providing policy and charging control in an information-centric network are described. An interest packet is transmitted from a content consumer to a holder through a gNB, ICN-PoA and ICN-GW. The interest packet has a prefix identifying content to be retrieved and a type field indicating an interest packet. The ICN-PoA modifies the interest packet to include a type of service (TS) field having the identity of the consumer and then transmitted to the ICN-GW when the content is neither created nor cached inside the 5G network. A data packet that includes the prefix, a type field indicating a data packet and the TS field is returned from the ICN-GW. The data packet is modified by the ICN-PoA to remove the TS field and transmitted to the consumer. The interest and data packets are logged and reported to an ICN-CF for generation of charging records.

  • Patent number: 11895475
    Abstract: A rear side of a vibration part of a speaker is covered by a cover member, and a duct is provided at the cover member. The cover member has a recessed portion, and an air flow path is formed inside the recessed portion. A circuit part is mounted on an outer surface of the cover member, and a heat sink provided in the air flow path is connected to the circuit part to allow heat conduction. Due to vibration of the vibration part, an airflow in the air flow path is accelerated and thus the effect of dissipating heat from the heat sink is increased.

  • Patent number: 11889019
    Abstract: Systems and methods for categorizing received calls based on early call information are disclosed. Early call information can be audio, video, other sensor data, or other data collected via a calling device during call setup or any time before the call is routed to or accepted at a receiving device. A call and early call information associated with the call are received. A call characteristic, which can be a purpose or topic of the call, is identified using the early call information. Based on the call characteristic, the received call is categorized and a relative priority for the call is assigned. The call can be routed based on the early call information, and a suggested response to the call can be identified. In some implementations, a machine learning model is trained to categorize received calls based on early call information.

  • Patent number: 11832426
    Abstract: The present disclosure describes thermal mitigation for an electronic speaker device and associated systems and methods. The thermal mitigation includes monitoring several thermal zones to determine or estimate thermal conditions in corresponding parts of the electronic speaker device. The thermal zones may include a System-on-Chip (SoC) integrated circuit (IC) component, audio components including power-dissipating IC components, and a temperature of an exterior surface of a housing component of the electronic speaker device. To mitigate thermal runaway, different throttling schemes may be triggered based on the thermal zones exceeding certain thermal limits. The throttling schemes may include reducing the amount of power supplied to the SoC, reducing audio power of the audio components to a lower wattage, or manipulating SoC cores such as by disabling one or more of the cores or adjusting utilization of the SoC cores.
