  • Publication number: 20190246481
    Abstract: Embodiments disclosed herein include a plasma source, an abatement system and a vacuum processing system for abating compounds produced in semiconductor processes. In one embodiment, a plasma source includes a dielectric tube and a coil antenna surrounding the tube. The coil antenna includes a plurality of turns, and at least one turn is shorted. Selectively shorting one or more turns of the coil antenna helps reduce the inductance of the coil antenna, allowing higher power to be supplied to the coil antenna that covers more processing volume. Higher power supplied to the coil antenna and larger processing volume lead to an improved DRE.

  • Publication number: 20190223101
    Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up-radio (WUR) discovery frame for a recipient electronic device, where the WUR discovery frame includes an operating class of a wireless local area network (WLAN) associated with the electronic device. The operating class may specify a regulatory domain and a channel set of the WLAN. Moreover, the WUR discovery frame may include an index of a channel in the channel set. Furthermore, the WUR discovery frame may include a compressed or a partial identifier associated with the electronic device or the WLAN. The amount of compression may be based at least in part on a communication environment of the electronic device, such as a number of electronic devices, or a number of neighboring WLANs. Thus, the WUR discovery frame may have a variable size or length.

  • Patent number: 10350599
    Abstract: A microfluidic exosome profiling platform integrating exosome isolation and targeted proteomic analysis is disclosed. This platform is capable of quantitative exosomal biomarker profiling directly from plasma samples with markedly enhanced sensitivity and specificity. Identification of distinct subpopulation of patient-derived exosomes is demonstrated by probing surface proteins and multiparameter analyzes of intravesicular biomarkers in the selected subpopulation. The expression of IGF-1R and its phosphorylation level in non-small cell lung cancer (NSCLC) patient plasma is assessed as a non-invasive alternative to the conventional biopsy and immunohistochemistry. Detection of ovarian cancer also is assessed. The microfluidic chip, which may be fabricated of a glass substrate and a layer of poly(dimethylsiloxane), includes a serpentine microchannel to mix a fluid and a microchamber for the collection and detection of exosomes.
