Patent number: 11938537Abstract: A 3D printing system and methods to selectively pattern dense feedstock based on selective inhibition sintering (SIS). A sintering selectivity agent (inhibitor or promoter) is selectively deposited on a build layer according to the pattern boundary. When the layers are built-up and the part is sintered, the inhibited region remains unbound, thus defining the edge of the part. The material contain powder embedded in cohesive binder that make the adjacent layer adhere together. The build process involves forming the sheets of dense feedstock embedded binder, followed by depositing ink to promote selective sintering onto the layer. Once the build is complete, the process continues with the binder removal, sintering and finishing processes.Type: GrantFiled: August 1, 2022Date of Patent: March 26, 2024Assignee: Xerox CorporationInventors: Mahati Chintapalli, Sean Garner, Ashish Pattekar, Anne Plochowietz

Patent number: 10950406Abstract: A transient electronic device includes electronic elements (e.g., an SOI- or chip-based IC) and a trigger mechanism disposed on a frangible glass substrate. The trigger mechanism includes a switch that initiates a large trigger current through a self-limiting resistive element in response to a received trigger signal. The self-limiting resistive element includes a resistor portion that generates heat in response to the trigger current, thereby rapidly increasing the temperature of a localized (small) region of the frangible glass substrate, and a current limiting portion (e.g., a fuse) that self-limits (terminates) the trigger current after a predetermined amount of time, causing the localized region to rapidly cool down.Type: GrantFiled: June 6, 2019Date of Patent: March 16, 2021Assignee: Palo Alto Research Center IncorporatedInventors: Gregory Whiting, Scott J.

Patent number: 9676382Abstract: Hybrid vehicle design circuitry quantifies values for utility/disutility variables of a hybrid vehicle design by evaluating a hybrid vehicle model over a collection of drive cycles/routes. The utility/disutility values include at least one of: total time or additional time beyond a reference time needed for the hybrid vehicle design to complete the drive cycles/routes, a fraction or number of the drive cycles/routes for which the hybrid vehicle design fails to achieve a target velocity, and amount of time or distance over which the hybrid vehicle design fails to achieve a target acceleration or the target velocity over the drive cycles/routes.

Patent number: 9539736Abstract: A mechanical method for producing micro-scale and nano-scale textures that facilitates, for example, the cost-effective production of nanostructures on large-scale substrates, e.g., during the large-scale production of thin-film solar cells. A “scratcher” (multi-pointed abrasion mechanism) is maintained in a precise position relative to a target substrate such that micron-level features (protrusions) extending from the scratcher's base structure are precisely positioned to contact a surface material layer of the target substrate with a predetermined amount of force, and then moved relative to the substrate (e.g., by way of a conveying mechanism) while maintaining the pressing force such that the micron-level features define elongated parallel nano-scale grooves and/or form nano-scale ridges in the surface material layer (i.e., by mechanically displacing) portions of the surface material layer to form the nano-scale grooves/ridges).Type: GrantFiled: August 7, 2012Date of Patent: January 10, 2017Assignee: Palo Alto Research Center IncorporatedInventors: David Eric Schwartz, Matthew D.
