Patent number: 10976474Abstract: In implementations of anti-static lens coatings, a device lens comprises an anti-static material disposed on an exterior of the device lens. A hard coat material is disposed as a layer over the anti-static material, where the anti-static material is effective to prevent static build-up on the layer of the hard coat material. The anti-static material can include a first surface treatment disposed on the anti-static material, where the first surface treatment binds the anti-static material to the device lens. The anti-static material can also include a second surface treatment disposed on the anti-static material, where the second surface treatment binds the anti-static material to the hard coat material.Type: GrantFiled: November 6, 2017Date of Patent: April 13, 2021Assignee: Motorola Mobility LLCInventors: Richard W. Brotzman, Jr., Deborah M. Paskiewicz

Patent number: 10802546Abstract: In implementations of device component exposure protection, a computing device includes device components enclosed within a housing. The device components are assembled within the housing and enclosed within the housing upon completion of assembly of the computing device. The computing device further includes a protective material contained within the housing, which fills void spaces around the device components. The protective material prevents exposure of the device components to external matter that the computing device is exposed to upon completion of the assembly.Type: GrantFiled: July 22, 2019Date of Patent: October 13, 2020Assignee: Motorola Mobility LLCInventors: Richard W.
