  • Patent number: 10762922
    Abstract: A method of assembly a dual stage actuated suspension includes either applying an adhesive to a microactuator motor and then B-staging the adhesive, or applying an adhesive that has already been B-staged such as in film adhesive form to the microactuator then assembling the microactuator into a suspension and then finishing the adhesive cure. The adhesive can be applied to bulk piezoelectric material, with the adhesive being B-staged either before or after it is applied to the bulk piezoelectric material, and the piezoelectric material then singulated into a number of individual piezoelectric microactuators. The method allows greater control over how much adhesive is used, and greater control over spread of that adhesive and control over potential contamination, than traditional liquid epoxy dispense methods.

  • Publication number: 20200273458
    Abstract: The present disclosure provides a method, an apparatus and a device for implementing a voice application and a computer readable storage medium, which determine a feedback content and a template identifier corresponding to a voice command of a user on a server side, and the determination result is performed by the IoT device. As the Internet information is iteratively updated, the voice command is also updated, the processing function of the voice command can be updated on the server side, so that the voice application in the IoT device does not need to be updated. Therefore, the processing capability of the voice application can be updated without upgrading the voice application itself, thereby alleviating the problem of an excessively long upgrade process due to the OTA upgrade process in the prior art.

  • Publication number: 20200251133
    Abstract: A PZT microactuator such as for a hard disk drive has a restraining layer bonded on its side that is opposite the side on which the PZT is mounted. The restraining layer comprises a stiff and resilient material such as stainless steel. The restraining layer can cover most or all of the top of the PZT, with an electrical connection being made to the PZT where it is not covered by the restraining layer. The restraining layer reduces bending of the PZT as mounted and hence increases effective stroke length, or reverses the sign of the bending which increases the effective stroke length of the PZT even further. The restraining layer can be one or more active layers of PZT material that act in the opposite direction as the main PZT layer. The restraining layer(s) may be thinner than the main PZT layer.
