  • Publication number: 20240240126
    Abstract: Provided herein is a resource-independent and cost-efficient antimicrobial susceptibility testing (AST) system or apparatus that can rapidly process a large number of samples. The AST system includes a barcode-like cell sensor based on an adaptive linear filter array for implementing a fully automatic and microscope-free method for counting a very small volume of cells in samples, wherein suspended cells concentrate into microbars with various lengths proportional to the number of cells. The AST system also includes an on-chip culture that takes much less time than standard methods, thereby realizing a low-cost and resource-independent platform for portable AST, from which results can be obtained through a portable device such as a cell phone.

  • Publication number: 20240222491
    Abstract: A SiC-based MOSFET device and a method for manufacturing the same. Layout design of SiC-based MOSFET devices is optimized, which keeps the JFET region while introducing shielding regions extending into the JFET region, thereby retaining the current flow area of the JFET region to a great extent; each shielding region is connected to the respective well region and extends into the JFET region along a diagonal direction of the cellular structure, effectively shielding high electric field regions when the device is reverse biased, and significantly enhancing the device's reliability. The shielding regions and the well regions are simultaneously formed, requiring no additional process, avoiding increase in complexity and cost of manufacturing. This approach achieves low on-resistance and prevents a decrease in reliability caused by the electric field strength at the bottom of the gate oxide layer exceeding a critical breakdown electric field strength of the gate oxide layer.

  • Publication number: 20240211442
    Abstract: Some disclosed embodiments are directed to methods and systems for performing pair-wise delta compression. For example, systems obtain a set of files to be compressed into a single compressed file. The system identifies different attributes related to the set of files. For each file in the set of files, the system predicts an optimized set of candidate compression files and calculates a delta between each file in the optimized set and the target file corresponding to the optimized set. After identifying the smallest delta, the system compresses the selected pair of files associated with the smallest delta in order to generate the single compressed file for the set of files.

  • Patent number: 11564169
    Abstract: An interface circuit in a device, e.g., an access point, may perform link adaptation. During operation, the interface circuit may provide a wake-up frame, e.g., a LP-WUR packet, associated with a channel in a band of frequencies, where the wake-up frame is intended for a wake-up radio in a recipient device. Then, the interface circuit may receive, from the recipient device, feedback information associated with a second channel in a second band of frequencies, where the feedback information is associated with a main radio in the recipient device. Based at least in part on the feedback information, the interface circuit may estimate one or more communication metrics associated with the channel in the band of frequencies. Moreover, based at least in part on the one or more communication metrics, the interface circuit may determine a data rate for use in communication via the channel in the band of frequencies.
