Patent number: 9338667Abstract: A drilling apparatus (100) includes a drill bit (200), a heating assembly, a cooling assembly, and a digging assembly. The heating assembly is configured to rapidly heat a material to be drilled at a target location. The heating assembly includes one or more first discharge structures (520) configured to discharge a high-temperature substance at the target location of the material. The cooling assembly includes one or more second discharge structures (440) configured to discharge a low-temperature substance at the target location of the material. The digging assembly is configured to remove substrate from the material at the target location.Type: GrantFiled: April 18, 2011Date of Patent: May 10, 2016Assignee: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventor: Yuchen Ma

Patent number: 8597405Abstract: An illustrative filter includes an electret material, which has a long-lasting electric charge, that is at least partially coated or covered with a conductive layer. An optional insulation layer may be disposed over at least part of the conductive layer. If the electret material has a positive charge, then the filter attracts particles with a negative charge, and vice versa. The filter adsorbs the attracted particles until it becomes saturated with particles, at which point the conductive layer is charged to have a polarity that is opposite the built-in polarity of the electret and that matches the polarity of the adsorbed particles. The charged conduction layer repels the adsorbed particles from the filter, cleaning the filter for continued use.Type: GrantFiled: August 23, 2011Date of Patent: December 3, 2013Assignee: Empire Technology Development LLCInventor: Yuchen Ma
