Abstract: Analysis of a breath sample is a noninvasive point-of-care tool with ever increasing screening and clinical applicability. Herein we describe a method to analyze the content of low-level, trace volatile organic compounds from alveolar breath captured as a breath sample from a patient suspected of having a disease related to coronavirus infection. The breath sample is then analyzed using a gas phase analysis methodology, such as gas chromatography-mass spectroscopy (“GCMS”), to generate an analysis result, such as a GCMS spectrum. A computer system is then used to develop a fingerprint pattern from the analysis result. The fingerprint pattern is then used to determine a patient status for the patient. The fingerprint pattern is typically a grouping of 75 to 450 compounds of known concentration which are indicative of a particular disease related to coronavirus.

Abstract: Systems and methods for efficiently and securely requesting and receiving, from a remote service, data for multiple accounts associated with the same device or application. In one example, a client device is configured to request application data for all accounts associated with the device or application installation using a single remote procedure call, rather than requiring separate calls for each account, and to do so by providing a single identifier rather than including identifiers specific to each associated account. The remote service is further configured to return the requested information in a manner that obfuscates the account identifiers and thus limits their potential use if the communication is intercepted, such that the application data can be efficiently transmitted together even where security or other concerns would otherwise dictate that separate transmissions should be made for each account.

Each split point defines an upper limit or lower limit for the range of clustering key values a data block in the third group.

Abstract: A laser radar includes: a laser, an optical transmission system, a 1-dimensional array of photo-detectors, an optical reception system, and an electronic control system. The laser emits a wavelength of light, and the optical transmission system shapes the light into a beam, and scans the beam along a fan of transmission light paths toward a target. The photo-detectors are capable of time-of-arrival measurements and are sensitive to the wavelength of light. The optical reception system collects the laser light reflected from the target along a fan of reception light paths. The electronic control system synchronizes the scan of the beam with a respective time-of-arrival measurement from each of the photo-detectors, and analyzes the time-of-arrival measurements. The system is configured for all of the transmission light paths and all of the reception light paths to lie in one plane, with all of the reception light paths intersecting with at least one of the transmission light paths.

Abstract: A circuit and method for detecting a failure of a switching power device is disclosed. The circuit and method utilize a Kelvin connection of a four-terminal configuration of the switching power device to sense a resistance of at least one wire-bond. The resistance corresponds to a defect or defects in the at least one wire-bond and so it can be used to detect a failure before damage occurs. A threshold used for detecting the failure can be adjusted to accommodate variations in the switching power device and/or the application in which it is being used. Additionally, the failure detection is carried out at a period after the switching power device is turned ON to prevent switching transients from affecting the detection.

Abstract: Infused oil polishing systems and methods reduce or remove chlorophyll from bulk biomass saturated ethanol. A processing vessel includes a valved input port for receiving a biomass mixture and a valved output port for expelling a polished mixture containing the desired extract. The vessel is pressurized or evacuated, causing the chlorophyll-containing carbon to be trapped by the filter assembly as the desired extract mixture is discharged. The equipment operates at relatively low pressures of 40 psi or less, and one operator can run multiple units. The end user can control the degree of polishing by adjusting the amount of media used and resident time. The basic apparatus can also be modified to run in parallel or series combinations to increase throughput. An optional elevating rack provides for ease of cleaning, and no expensive ancillary equipment needs to be purchased.
