Abstract: An automated onboarding method provides a form which a prospective client fills out, preferably electronically, which is received by a customer relations management (CRM) software. The CRM software assigns a customer account number and populates the CRM account with the information from the form in an automated manner. At least one document is generated, preferably automatedly and sent to the potential customer to execute. When received the system may automatedly complete the onboarding process, possibly including sending an account transfer or funding form signed by the potential client to a third party for execution and updating to establish the account when funded, potentially with no human interaction during the process, or if interaction, only for authentication of the legitimacy of the applicants.

Abstract: A suppressor for reducing muzzle flash during firing of a firearm. The suppressor includes an auto purge channel configured to direct gas to a distal end of the suppressor adjacent an exit point of a projectile. In one example, the auto purge channel enables gas to saturate an area of the suppressor in front of the projectile. For example, the auto purge channel directs gas to the distal end of the suppressor at a speed that is greater than a speed of the projectile. In another embodiment, the projectile travels through combustion gasses transferred by the auto purge channel to reduce muzzle flash. In yet another example, the auto purge channel runs parallel to a central bore of the suppressor.

Abstract: A system receives medical data from multiple physiological monitor devices in various forms and formats. A data normalization process identifies each attribute type in the medical data reported by each device and assigns a unique attribute identifier. All parameters associated with an attribute are also identified and assigned a unique parameter identifier. The data normalization process uses this information to create a standardized data set for analysis. A rules processing engine applies alert and reporting rules to the standardized data set to generate a patient report and alerts for patient data that is beyond thresholds defined by the alert rules. The system provides default alert rules that may be overridden by clinic rule or manufacturer rules. Artificial intelligence (AI) principles may be applied using training set(s) of data to teach the rules processing engine to use the AI alert rules for data analysis.

Abstract: Plant eradication and stressing of plants using illumination signaling where a short-time dual component, low energy, unnatural set of irradiances is applied, with no mutagenic or high radiative energy transfers in any wavelength for eradication by substantial high temperature thermally-induced leaf and plant component failure or incineration. An Indigo Region Illumination Distribution of wavelength 300 nm to 550 nm is directed to plant foliage and/or a plant root crown, while infrared radiation that is substantially Medium Wavelength Infrared radiation of 2-20 microns wavelength, 2.4-8.0 microns preferred, is directed to a plant root crown and/or soil immediately adjacent the root crown. The Indigo Region Illumination Distribution can pass through the MWIR emitter to form a compact illuminator that uses specific unnatural irradiances that provide unexpected plant control. The MWIR emitter can comprise borosilicate glass at 400° F. to 1000° F.

Abstract: Methods are disclosed for the purification of crude compositions comprising 2,5-furandicarboxylic acid, dimethyl ester (FDME) or other diester derivatives (e.g., dialkyl ester derivatives) of 2,5-furandicarboxylic acid (FDCA), by crystallization. In this regard, certain solvents, and classes of solvents, have been discovered to promote the selective crystallization of FDME over impurities often generated in its production by FDCA esterification and other upstream processing steps. Importantly, certain impurities that are selectively removed include those that would otherwise be detrimental to the color and/or color stability of the purified composition. Other improvements in crystallization reside in the use of techniques such as liquid-liquid extraction and pre-treatment of the crystallization solution by contact with a solid medium.
