  • Publication number: 20240111840
    Abstract: An electronic device uses a tiling scheme selected from among a set of tiling schemes for processing instances of input data through a neural network. Each of the tiling schemes is associated with a different arrangement of portions into which instances of input data are divided for processing in the neural network. In operation, processing circuitry in the electronic device acquires information about a neural network and properties of the processing circuitry. The processing circuitry then selects a given tiling scheme from among a set of tiling schemes based on the information. The processing circuitry next processes instances of input data in the neural network using the given tiling scheme. Processing each instance of input data in the neural network includes dividing the instance of input data into portions based on the given tiling scheme, separately processing each of the portions in the neural network, and combining the respective outputs to generate an output for the instance of input data.

  • Publication number: 20240031466
    Abstract: Exemplary embodiments relate to techniques for managing contact information received in the context of a messaging system. Messages may be received from known contacts which contain user contact records for third parties. Based on the trust relationship with the known contacts, the user contact record is placed in a contact record repository for later retrieval. When another message is received which either references the user contact record or is from the third party referenced in the user contact record, a dialog box is presented offering the user the opportunity to add the user contact record as an address entry in the address book of the device.

  • Patent number: 11218453
    Abstract: A messaging system interacts with the messaging applications of customer, admin, and agent clients to support encrypted communications among customers and businesses. To register as an agent of the business, an agent client sends registration information to the messaging system and receives a barcode in response. The messaging system validates information about the barcode received from the admin client and sends a validation code to the admin client. The admin client displays the validation code, and the validation code is entered into the agent client. The admin client generates a membership list including an agent client identifier, digitally signs the membership list, and provides the signed membership list to the messaging system. When a customer messages the business, the messaging system forms a customer group using the signed membership list and distributes the message to the agent clients in the group.

    Abstract: A sealing gasket with two deformation spaces is configured to be mounted in a cup-shaped structure and has a through bore that opens on the top and bottom sides of the sealing gasket. The sealing gasket is characterized in that: an inner deformation space and an outer deformation space extend downward into the top side of the sealing gasket, the inner deformation space is adjacent to the through bore such that an inner deformable portion is formed between the inner deformation space and the through bore, and the outer deformation space is adjacent to the outer wall of the sealing gasket such that the outer wall forms an outer deformable portion corresponding to the outer deformation space. The two deformation spaces provide the sealing gasket with enhanced deformability to adapt to a through hole whose diameter may vary within engineering tolerances.

  • Patent number: 10121638
    Abstract: An atmospheric-pressure plasma jet generating device is disclosed, which comprises a housing, a discharge tube, an air inlet, and an outlet. The air inlet is connected to the outlet and the discharge tube. The discharge tube includes an internal electrode, a first dielectric material, and an external electrode. The first dielectric material is placed between the external electrode and the internal electrode, and there are some channels between internal electrode and first dielectric tube. An external power source is electrically connected to the internal electrode and the external electrode to generate a high electric field within the discharge tube. When the working gas flows through the discharge tube from the air inlet, the plasma is generated by the high electric field, and then flows out through the outlet. The present invention can generate non-thermal atmospheric-pressure plasma jet for biomedical processing.
