  • Publication number: 20240095840
    Abstract: A computer-assisted method for providing re-quotations for insurance coverage may include receiving a list of insurance leads corresponding to individuals who received a previous quotation for insurance coverage but did not purchase the insurance coverage and identifying a difference between the previous quotation and a new quotation. This difference may include an increase in offered insurance coverage and/or a reduction in cost. A computing device may calculate a probability for each of the individuals on the list using a regression model based, at least in part, on the identified difference. In some cases, the regression model may be associated with individual states. In other cases, the regression model may correspond to a plurality of states. The regression model may output a probability that a resident of a particular state will purchase insurance in response to a re-quotation for insurance coverage, where individuals may then be ranked based on the probability.

  • Publication number: 20230415612
    Abstract: The present disclosure provides a method of managing thermal loads in an electric vehicle and controlling various electronic components of a thermal management system. The method may comprise heating a battery coolant of a battery coolant loop utilizing waste heat from a battery to form a heated battery coolant, heating a refrigerant of a battery refrigeration loop by exchanging heat with the heated battery coolant, and measuring refrigerant temperature(s) and pressure(s) at an output of a chiller. The measured temperature(s) and pressure(s) may be utilized by the thermal management system as feedback signals for performing a proportional-integral-derivative control to compute an electronic expansion valve position command.

  • Publication number: 20230365026
    Abstract: The present disclosure provides a method of managing thermal loads in a fuel cell electric vehicle. The method may include measuring a coolant temperature at an outlet of a fuel cell radiator, calculating a fuel cell coolant flow value, calculating a fuel cell heat generation value, calculating a feedback portion of a fuel cell radiator fan speed command using the coolant temperature at the outlet of the fuel cell radiator, calculating a feedforward portion of the fuel cell radiator fan speed command using an ambient temperature, the fuel cell coolant flow value, and the fuel cell heat generation value calculating the fuel cell radiator fan speed command using the feedforward portion and the feedback portion, and controlling a fuel cell radiator fan speed using the fuel cell radiator fan speed command.

  • Patent number: 11588098
    Abstract: A multi-level piezoelectric actuator is manufactured using wafer level processing. Two PZT wafers are formed and separately metallized for electrodes. The metallization on the second wafer is patterned, and holes that will become electrical vias are formed in the second wafer. The wafers are then stacked and sintered, then the devices are poled as a group and then singulated to form nearly complete individual PZT actuators. Conductive epoxy is added into the holes at the product placement step in order to both adhere the actuator within its environment and to complete the electrical via thus completing the device. Alternatively: the first wafer is metallized; then the second wafer having holes therethrough but no metallization is stacked and sintered to the first wafer; and patterned metallization is applied to the second wafer to both form electrodes and to complete the vias. The devices are then poled as a group, and singulated.

  • Patent number: 11303499
    Abstract: Techniques for improving communications efficiency between pairs of communication nodes running within a computer system are described herein. Potential locations for placing a communication node are evaluated using one or more fitness values wherein the fitness value is based at least in part on one or more system metrics associated with placing a communication node in the potential location. If an improved location is found based on the fitness value, the communication node may be migrated to the new location, thus improving system efficiency.

  • Patent number: 11241545
    Abstract: A plunger, a needle assembly and a retractable syringe comprising same are provided. The plunger comprises a plunger member and a plunger outer having a lock spring that prevents or impedes movement of the plunger member after needle retraction. The plunger further comprises another locking member for engaging the barrel to prevent or impede further movement of the plunger outer after delivery of fluid contents. The plunger member has a plunger seal which engages a retractable needle of the needle assembly for retraction. The retractable needle comprises a cannula and needle body with a plurality of fluid channels that co-operate with a fluid conduit of the plunger seal to efficiently direct fluid to the cannula. A needle retainer comprises a plurality of barbed arms releasably coupled to the needle body, whereby an ejector with tabs facilitates release of the retractable needle from the needle retainer to allow compressed spring-driven retraction.

  • Publication number: 20210405012
    Abstract: A system and process may be used to test water samples to measure ATP and/or estimate a microbial population, for example using an adenosine triphosphate (ATP) based assay. The system includes a device that is use in combination with single-use or disposable cartridges. The cartridge receives the water sample and is pre-loaded with one or more reagents. The device receives the cartridge and contains physical, electronic and/or mechatronic devices that interact with cartridge. One or more actions such as metering, mixing and conveying are performed automatically by elements of the device and/or cartridge. A sensor in the device measures light produced in the cartridge from a reaction with ATP in the water sample. Optionally, the cartridge also contains a pre-loaded amount of ATP, which is used to provide an internal reference or calibration measurement.
