Publication number: 20240177759Abstract: Ferroelectric diodes comprising materials such as aluminum scandium nitride (AlScN) or hafnium zirconium oxide (HfZrO2) may be formed atop semiconductor structures such as CMOS wafers to create storage memory cells. search Ternary Content Addressable Memory (TCAM) cells, and/neural circuitry. The diodes are non-volatile and field programmable via pulsing to a pulse-number-dependent analog state, with high on/off and self-rectifying ratios. Cells may be formed, for example, with two diodes that are oppositely polarized, and may be achieved without transistors to form, for example, 0T-2R structures.Type: ApplicationFiled: March 30, 2022Publication date: May 30, 2024Inventors: Deep JARIWALA, Roy H. OLSSON, III, Eric Andrew STACH, Xiwen LIU, Dixiong WANG, Jeffrey ZHENG, Merrilyn Mercy Adzo FLAGBENU

Patent number: 11013321Abstract: A drawer slide with lock mechanism has an elongated outer slide member extendably coupled to an inner slide member. A latch arm or pin is fixed to the inner slide member for latching by a lock mechanism fixed to the outer slide member. The lock mechanism uses a latch receiver that rotates with respect to the lock mechanism and is in a travel path of the latch arm. A lever arm rotates with respect to the lock mechanism and is positionable to block rotation of the latch receiver in a locked position to retain the latch arm. A motor drives a cam to position the lever arm to free the latch receiver from the locked position.Type: GrantFiled: February 15, 2018Date of Patent: May 25, 2021Assignee: Accuride International Inc.Inventors: Darush David Hashemi, Xiaoping Zhou, Xiwen Wang

Patent number: 10116853Abstract: An integrated image sensor and lens assembly comprises a lens barrel, an adapter tube, and a lens mount. The lens mount includes a first thread having a first pitch and the tube adapter comprises a second thread reciprocal to the first thread. The first and second threads secure the tube adapter within the lens mount. The tube adapter further comprises a third thread having a second pitch different than the first pitch, and the lens barrel comprises a fourth thread reciprocal to the third thread. The third and fourth threads secure the lens barrel within the tube adapter. A rotation of the tube adapter with respect to the lens barrel and the lens mount causes linear movement of the lens barrel and the lens mount with respect to the tube adapter in a same direction along the optical axis.Type: GrantFiled: November 11, 2015Date of Patent: October 30, 2018Assignee: GoPro, Inc.Inventors: Steven Xiwen Wang, Karen Ann Baumgartner, Emilio Graff

Patent number: 10103373Abstract: Diaphragm paper, and a preparation method and an application thereof. The diaphragm paper comprises a first layer, a second layer, and a third layer, wherein the second layer is located between the first layer and the third layer; the first layer and the third layer are loose layers, of which the average aperture is larger than 10 ?m and the basis weight is 5 to 30 g/m2; and the second layer is a compact layer, of which the average aperture is smaller than 5 ?m and the basis weight is 2 to 15 g/m2. The compact layer has small aperture and good insulating performance, and is capable of effectively insulating a positive electrode and a negative electrode. The loose layers have good liquid permeability and electrolyte absorptivity, and can guarantee the discharge performance of a battery. The material is further advantageous in having good dimensional stability and being thin, so that a battery can achieve high capacity.Type: GrantFiled: January 23, 2013Date of Patent: October 16, 2018Assignee: South China University of TechnologyInventors: Jian Hu, Jin Long, Xiwen Wang
