Publication number: 20210295991Abstract: Identification and monitoring of healthcare issues includes determining how to process input data based on at least one of identity of a user device that transmits the input data to the system and categorization of the input data. A new record is created in a database of healthcare issues in a healthcare facility where the user device is located when the input data is received. Anonymous reporting of issues is supported by storing an identifier of the user device that transmits the input data to the system, so that the anonymous reporter can be invited by a manager to join in an anonymous chat session. Recording of data during supervisor walkrounds is supported by setting up scheduled walkrounds with default labels to simplify input of identified healthcare issues, while allowing for custom labels to be entered when needed.Type: ApplicationFiled: April 7, 2021Publication date: September 23, 2021Applicant: SAFE & RELIABLE HEALTHCARE LLCInventors: Allan S. FRANKEL, Michael W. LEONARD, Terri CHRISTENSEN FRANKEL, Joshua PROULX, Daniel Joseph CRAMER, John D. DUCE, Jared GOODEY, Chad LANENGA

Patent number: 10919999Abstract: The present invention relates to a method of preparing an aqueous dispersion of multistage polymer particles comprising contacting under emulsion polymerization conditions and in a staged fashion an aqueous dispersion of carboxylic acid functionalized core polymer particles with first monomers and second monomers. The core comprises structural units of a high Tg hydrophobic monomer and/or the first monomers comprise a high Tg hydrophobic monomer, and the second monomers comprise at least 80 percent styrene. The high Tg hydrophobic monomer is cyclohexyl methacrylate, isobornyl methacrylate, 4-t-butyl methacrylate, t-butylstyrene, or n-butyl methacrylate, or a combination thereof. The multistage polymer particles are useful as opaque polymers, which are used in pigmented coating formulations to reduce the load of TiO2. The particles exhibit excellent collapse resistance and unusually low dry bulk density, and do not require acrylonitrile to achieve this desired combination of properties.Type: GrantFiled: August 30, 2019Date of Patent: February 16, 2021Assignee: Rohm and Haas CompanyInventors: James K.
