Publication number: 20220138780Abstract: Disclosed is a churn prediction system that predicts with a high level of accuracy which users will and which users will not stop opening the app over a 30-day time period. To this end a model is created using historical event data where the churn-related behavior of each user is known. New event data is then applied to the model to determine the likelihood of each user churning in the future. With these prediction scores a user is then qualified as falling into one of three classifications: low-risk, medium-risk, or high-risk of churn.Type: ApplicationFiled: January 14, 2022Publication date: May 5, 2022Inventors: Elizabeth Marjory Orr, Gary Todd Johnson, Neel Banerjee

Patent number: 8756025Abstract: Methods and apparatus are provided related to thermal protection of electrical batteries. A sensor senses the temperature of a battery and a corresponding digital signal is digitally derived. Date, time and temperature data are written to storage media. A time-rate-of-change of the battery's temperature is determined and used to establish operational periodicity. Stored digital data can be communicated to another entity, temperature or time-rate-of-change values used to trigger an alarm or system shut-down, and so on. Electronic circuitry toggles between an active mode and a power-conserving sleep mode in accordance with periodic operating schedule.Type: GrantFiled: January 18, 2011Date of Patent: June 17, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Neel Banerjee, Anton Nicholas Clarkson
