  • Publication number: 20210120344
    Abstract: An electro-acoustic transducer has an acoustic diaphragm and a voice-coil. The diaphragm defines a first major surface. A flange extends from the diaphragm in a direction opposite the first major surface. The voice-coil has a first plurality of windings positioned adjacent to the acoustic diaphragm and a second plurality of windings positioned distally from the acoustic diaphragm. The flange overlaps the first plurality of windings. The flange and the windings can be adhesively bonded with each other to form a lap joint. The lap joint can transfer force from the voice-coil to the diaphragm.

  • Patent number: 10768067
    Abstract: An apparatus with embedded water detection and heater includes a substrate including a number of conductive traces and a lid including multiple electrodes. Each electrode is coupled to at least one of the conductive traces through vias. A sensor is placed inside a cavity of the lid and is electrically coupled to one or more conductive traces of the substrate. A gel at least partially fills the lid and covers the sensor. The presence of water on the apparatus is detected by measuring a dielectric permittivity between at least two of the plurality of electrodes, and the electrodes can generate heat to eliminate the water.

  • Patent number: 9584476
    Abstract: Various examples provide a safety protection method, a firewall, a terminal device and a computer-readable storage medium. According to the method, a firewall injects a code module including a first function capable of modifying package safety information corresponding to an illegal application into a target process, and triggers the first function to modify the package safety information corresponding to the illegal application to make the illegal application fail to perform an operation due to the modified package safety information.

  • Patent number: 9501338
    Abstract: A method and apparatus for managing processes are provided, the method comprising: obtaining a process identifier for a process in an operating system; after the shutdown of the process by a user, determining, in response to a first system event of the operating system, whether a first set of event objects comprise the process identifier to generate an examination result; and if the examination result indicates that the first set of event objects comprise the process identifier, deleting the process identifier from the first set of event objects. The method and apparatus for managing processes effectively prevent a process that was shut down by a user from being unintentionally reinitiated.
