Patent number: 11814809Abstract: A foundation structure is made up of a screw that is vertically adjustable into a pile to a desired height, a ball joint connected to the screw, and load bearing components that can be adjusted on the ball joint in 3-dimensional space with respect to the position of the pile. The load bearing components include one or more plates that define one or more hollow slots into which one or more bolts can be held in place vertically while still having allowance for lateral motion. A load bearing plate at the top of the structure can be laterally translated based on movement of the bolt. The load bearing plate is removably coupled to the floor of a building. The structure allows for vertical, lateral, and angular adjustment, providing tolerance for foundation misalignments due to inconsistencies inherent to topography and/or offset between an intended and an actual point of installation.Type: GrantFiled: November 2, 2020Date of Patent: November 14, 2023Assignee: Samara Living Inc.Inventors: Thi Thuy Duong Tran, Margaret Bacon, Christopher Oliver, Nicole Voyen, Jean Chang

Publication number: 20160258667Abstract: A dry instant cold pack includes approximately 50 g-55 g raw chemical fill materials contained in a pouch having a water filling nozzle. The raw chemical fill material is preferably ammonium nitrate, calcium ammonium nitrate (CAN) or urea, and the bag or pouch is preferably made of PE or PE Nylon. The dry instant cold pack has lower manufacturing cost and is easy to carry, transport and store. To activate and use, the user simply adds some water through water filling nozzle to produce a cooling effect within 30 seconds. The one-way nozzle prevents the water from flowing back out of the pouch.Type: ApplicationFiled: February 26, 2016Publication date: September 8, 2016Inventors: Jeff Kruckman, Jean Chang

Patent number: 7931665Abstract: A filter system for temporary placement of a filter in an artery or vein is disclosed. The filter system includes a guidewire that is first positioned across a lesion within a vessel. The guidewire may include a distal stop. A slideable filter is then advanced along the guidewire using an advancing mechanism, typically an elongate member slideable over the guidewire and contacting the filter. A capture sheath may be disposed about the filter during advancement. Once the filter is positioned downstream of the lesion, the capture sheath is withdrawn, allowing the filter to expand. Further distal advancement of the filter is prohibited by the stop. After expansion of the filter, the capture sheath and the advancing mechanism are withdrawn from the region of interest, and removed from the patient's vessel. The filter may then be retrieved using a capture sheath or exchanged for a second filter after removing the first filter.Type: GrantFiled: October 24, 2007Date of Patent: April 26, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Ross Tsugita, Jean Chang

Patent number: 7179714Abstract: There is provided a method of fabricating a MOS transistor having a fully silicided gate, including forming a gate pattern and gate spacers on a semiconductor substrate, the gate pattern including a lower gate pattern, an insulating layer pattern, and an upper gate pattern, which are sequentially stacked. Source/drain regions are formed by implanting impurity ions into an active region using the gate pattern and the gate spacers as ion implantation masks. Then, a protecting layer is formed on the semiconductor substrate having the gate pattern, and the protecting layer is planarized until the upper gate pattern is exposed. Then, by removing the exposed upper gate pattern and the insulating layer pattern, the lower gate pattern is exposed. Then, the protecting layer is selectively removed, thereby exposing the source/drain regions. The exposed lower gate pattern is fully converted to a gate silicide layer, and a silicide layer is concurrently formed on the surfaces of the source/drain regions.Type: GrantFiled: February 24, 2005Date of Patent: February 20, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: You-Jean Chang, Myoung-Hwan Oh, Hee-Sung Kang, Choong-Ryul Ryou
