Patent number: 11298875Abstract: A three-dimensional (3D) inkjet printer is configured to build up an object by printing a series of layers and stacking them to form the object. In order to speed printing, drying of each layer is accelerated by using a pressure differential to extract liquid vehicle from the ink, and by moving the printed layer away from the inkjet print heads before drying so that the inkjet print heads may print the next layer. The dried printed layer may also be conditioned and/or cured. Dried printed layers are stacked at a build station to assemble the finished object.Type: GrantFiled: March 11, 2021Date of Patent: April 12, 2022Assignee: SAKUU CORPORATIONInventors: Philip Eugene Rogren, Morteza Vatani, Ronald Anthony Rojeski

Patent number: 8658310Abstract: A high capacity electrode includes a conducting substrate on which a plurality of support filaments are disposed. Each of the support filaments have a length substantially greater than their width and may include, for example, a carbon nano-tube (CNT), a carbon nano-fiber (CNF), and/or a nano-wire (NW). The support filaments are coated with a material, such as silicon, having a greater ion absorbing capacity greater than the neat support filaments. A trunk region of the support filaments proximate to the substrate is optionally kept free of ion absorbing material. This trunk region allows for the expansion of the ion absorbing material without detaching the support filaments form the substrate.Type: GrantFiled: November 6, 2012Date of Patent: February 25, 2014Assignee: Catalyst Power Technologies, Inc.Inventor: Ronald Anthony Rojeski

Patent number: 8481214Abstract: An electrode including structures configured to prevent an intercalation layer from detaching from the electrode and/or a structure configured to create a region on the electrode having a lower concentration of intercalation material. The electrode includes a support filament on which the intercalation layer is disposed. The support filament optionally has nano-scale dimensions.Type: GrantFiled: October 13, 2010Date of Patent: July 9, 2013Assignee: Catalyst Power TechnologiesInventor: Ronald Anthony Rojeski
