Publication number: 20240086856Abstract: A computer-implemented system and method are provided for adaptively controlling communication activity of a communication system. The method stores user information comprising contact preferences, a goal, and account information. The system may receive external information by a trigger engine which applies a trigger rule to determine a degree of relatedness between the goal and at least one of external information and the account information. When the degree of relatedness exceeds a threshold, then the contact preferences may be used to format a communication related to the external information based on the contact preferences. The system may then send the communication to the user by the communication entity according to the contact preferences, and, based on a feedback or lack of feedback from the user related to the communication, adjust at least one of the contact preferences, the trigger rule, or a weighting factor of the trigger rule.Type: ApplicationFiled: May 14, 2018Publication date: March 14, 2024Inventors: John C. Brenner, Donna Marie Greene, Carter C. Hansen, Tambra Nichols, Elizabeth Long Swindler, Keith Meade Sykes

Patent number: 10707800Abstract: A multi-pulse transformer with multiple taps provides a constant magnitude voltage output to a variable speed chiller's compressor motor over a range of input voltages. The 3-phase transformer includes primary windings and a plurality of secondary windings. The secondary windings are electromagnetically coupled with the associated primary winding. The primary windings include taps for receiving multiple input AC voltages and the secondary windings have a single output terminal for supplying a predetermined output voltage which, after rectification produces a DC multi-pulse waveform for powering a DC link of a variable speed drive. Alternatively the 3-phase transformer includes multiple taps on the secondary windings. Each of the primary windings has a terminal for receiving an input AC voltage. The taps of the secondary windings provide an output voltage that is converted to a multi-pulse waveform for powering a DC link of a variable speed drive.Type: GrantFiled: September 10, 2018Date of Patent: July 7, 2020Assignee: Johnson Controls Technology CompanyInventors: Zhiqiao Wu, John C.
