  • Publication number: 20230001040
    Abstract: An air sterilizing device has a casing, a wheel disc covered with microporous structures, a blower, and a sterilizing module. The casing has an air inlet and an air outlet. The blower located in the casing introduces the external air from the air inlet, and the external air is filtered and sterilized by the wheel disc and the sterilizing module. The filtered and sterilized air is discharged from the air outlet. The sterilizing module locates next to the wheel disc for sterilizing the air flowing through the sterilizing module and also for sterilizing the wheel disc by the relative rotation between the wheel disc and the sterilizing module. Bacteria and viruses attached to the wheel disc are eliminated, and the filtration and sterilization functions of the wheel disc are maintained. The efficacy and the efficiency of the air sterilizing device are therefore improved.

  • Publication number: 20230005852
    Abstract: An integrated circuit (IC) comprising an enhanced passivation scheme for pad openings and trenches is provided. In some embodiments, an interlayer dielectric (ILD) layer covers a substrate and at least partially defines a trench. The trench extends through the ILD layer from a top of the ILD layer to the substrate. A conductive pad overlies the ILD layer. A first passivation layer overlies the ILD layer and the conductive pad, and further defines a pad opening overlying the conductive pad. A second passivation layer overlies the ILD layer, the conductive pad, and the first passivation layer, and further lines sidewalls of the first passivation layer in the pad opening and sidewalls of the ILD layer in the trench. Further, the second passivation layer has a low permeability for moisture or vapor relative to the ILD layer.

  • Patent number: 11540276
    Abstract: A device may wirelessly communicate according to a first radio access technology (RAT) within a first bandwidth part (BWP) of a frequency spectrum in which wireless communications according to other RAT(s) also take place. The device may be instructed to operate/communicate within a second BWP of the frequency spectrum responsive to the device successfully completing a listen-before-talk (LBT) procedure within a specified portion of the second BWP, where the second BWP contains the first BWP while the first BWP does not contain the specified portion of the second BWP. The device may also be instructed to operate/communicate within a specified frequency band (SFB) of the frequency spectrum responsive to the device successfully completing an LBT procedure within the SFB, where the SFB is not contiguous with the frequency band that includes the first BWP. The device may then simultaneously operate within the second frequency band and the first frequency band.

  • Patent number: 11532479
    Abstract: A gate stack can be etched to form a trench extending through the gate stack, the trench removing a portion of the gate stack to separate the gate stack into a first gate stack portion and a second gate stack portion. A dielectric material is deposited in the trench to form a dielectric region, the dielectric region having an air gap in the dielectric material. The air gap may extend upward from beneath the gate stack to an area interposed between the end of the first gate stack portion and the end of the second gate stack portion. Contacts to the first gate stack portion and contacts to the second gate stack portion may be formed which are electrically isolated from each other by the dielectric material and air gap formed therein.

  • Publication number: 20220399006
    Abstract: A computer-implemented method, system and computer program product for providing high quality speech recognition. A first speech-to-text model is selected to perform speech recognition of a customer's spoken words and a second speech-to-text model is selected to perform speech recognition of the agent's spoken words during a call. The combined results of the speech-to-text models used to process the customer's and agent's spoken words are then analyzed to generate a reference speech-to-text result. The customer speech data that was processed by the first speech-to-text model is reprocessed by multiple other speech-to-text models. A similarity analysis is performed on the results of these speech-to-text models with respect to the reference speech-to-text result resulting in similarity scores being assigned to these speech-to-text models.
