Publication number: 20240077929Abstract: The present disclosure describes systems and methods associated with selective powering of an electronic display in response to sensed data indicating that the electronic display is not visible. By selectively enabling the electronic display between power states based on whether the electronic display is visible, a perceivably always-on electronic display may be provided without the electronic display being always-on, thereby balancing consumer interests with technical requirements of a relatively long battery life and correspondingly low power consumption.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Joseph F. Alverson, Brad W. Simeral, Daniel J. Drusch, Daniel P. Kumar, Derek J. DiCarlo, Ricky Wai Kit Yuen, Roberto G. Yepez, Shashi K.

Publication number: 20240077930Abstract: The present disclosure describes systems and methods associated with selective powering of an electronic display in response to operating conditions, additional data, and/or predicting that the electronic display is not going to be viewed or visible. By selectively enabling the electronic display between power states based on a prediction of when a viewer is expected to view the electronic display, a perceivably always-on electronic display may be provided without the electronic display being always-on, thereby balancing consumer interests with technical requirements of a relatively long battery life and correspondingly low power consumption.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Inventors: Joseph F Alverson, Brad W. Simeral, Daniel J. Drusch, Daniel P. Kumar, Derek J. DiCarlo, Ricky Wai Kit Yuen, Roberto G. Yepez, Shashi K.

Patent number: 11739258Abstract: Proppant particulates are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. In complex fracture networks, it can be difficult to deposit proppant particulates fully within the fractures. In addition, low crush strengths may result in problematic fines formation. Polyaromatic hydrocarbons, commonly encountered in various refinery process streams, may serve as an advantageous precursor to proppant particulates. Polyaromatic hydrocarbons may undergo crosslinking under acid-catalyzed conditions in an aqueous solvent in the presence of a surfactant to form substantially spherical particulates that may serve as effective proppant particulates during fracturing operations. In situ formation of the proppant particulates may take place in some cases.Type: GrantFiled: December 27, 2022Date of Patent: August 29, 2023Assignee: ExxonMobil Technology and Engineering CompanyInventors: Peter A. Gordon, Huaxing Daniel Zhou
