  • Patent number: 12252826
    Abstract: A method of preparing an electret by saturating a nonwoven fabric with a liquid, such as water, and removing the liquid via suction to generate charges by friction between the fabric fibers and the liquid is described. The saturating can be carried out, for example, by impinging the bottom side of the fabric with a jet or jets of water while the fabric is being pulled under a solid roller. Excess water can also be applied during a water quenching step of a meltblowing or spunbonding process. An apparatus for preparing an electret according to the presently disclosed methods is also described.

  • Publication number: 20240243716
    Abstract: Laser-marked packaged surface acoustic wave devices are provided. The laser-marked packaged surface acoustic wave device may include a package structure encapsulating a surface acoustic wave device on a first side of a piezoelectric substrate. The opposite side of the piezoelectric substrate can be directly marked using a laser. The laser may be a deep ultraviolet laser. By directly marking the piezoelectric substrate itself, the use of a separate marking film can be avoided, making the packaged surface acoustic wave device thinner. When the laser has a wavelength readily absorbed by the piezoelectric substrate, a relatively shallow marking may be made in the piezoelectric substrate. The markings can extend less than 1 micrometer into the piezoelectric substrate, so as not to affect the structural integrity of the piezoelectric substrate or the operation of the packaged surface acoustic wave device.

    Abstract: Methods, apparatuses, and systems are described for detecting the presence, location and movement of devices and associated users between networks. A device may determine and maintain data indicative of one or more devices in communication with a gateway device associated with a network in order to determine whether the device has been moved. The device may compare the data indicative of the devices in communication with the gateway device with other data indicative of devices detected at a second time to determine if the device has been moved to a new network.

  • Patent number: 11923817
    Abstract: Methods of making packaged surface acoustic wave devices are provided. The method may include forming a photosensitive resin coat over a cavity-defining structure encapsulating a surface acoustic wave device. The photosensitive resin coat may be formed using a spin-coating process, and then patterned to form a desired shape. Portions of the photosensitive resin may be removed from areas near the edge of the die, to facilitate separation of a wafer into individual dies. The method may also include forming a conductive structure using a plating process, where the conductive structure is located between the resin coat and the cavity defining structure. The photosensitive resin can include a phenol resin. The packaged surface acoustic wave devices made using a photosensitive resin coat may be relatively thin, and may have a height of less than 220 micrometers.
