Publication number: 20250070117Abstract: A doped cathode material for lithium-ion batteries is disclosed. Methods and systems are further provided for doping a cathode material for use in a lithium-ion battery. In one example, the doping may be a dry surface doping process. In some examples, dopants may stabilize a crystal structure of the cathode material and may result in fewer side reactions with an electrolyte as compared to an undoped cathode material. As such, cycling performance and capacity retention may be improved relative to the undoped cathode material. Further, in some examples, the doped cathode material produced with the dry surface doping process may have improved cycling performance and capacity retention relative to a comparable doped cathode material produced with a wet surface doping process.Type: ApplicationFiled: November 15, 2024Publication date: February 27, 2025Inventors: Yang Shi, Kitae Kim, Lixin Wang, Yingjie Xing, Andrew Millonig, Bryan Kim, Derek C.

Publication number: 20250057414Abstract: A monocular and/or a binocular system may be used to generate one or more images, or videos, of a subject's retina by scanning in one or two directions in one or two dimensions to, for example, measure and/or report fixation, smooth pursuit, and/or saccadic responses of the subject's eye. The scanning and/or image generation process may be optimized to correct for distortions in the subject's eye and/or improve SNR among one or a plurality of retinal images. In some cases, the retinal images may be used to train a retinal feature detection model and/or algorithm that may be used to make predictions and/or inferences regarding a visual pattern showing features of subsequently received retinal images. These models and/or predicted patterns present within the models may be used by the retinal feature detection model and/or algorithm to monitor features of the retina and, in some instances, track voluntary and/or involuntary eye motion.Type: ApplicationFiled: December 22, 2022Publication date: February 20, 2025Applicant: C.

Publication number: 20180252984Abstract: Apparatus and method for high-power multi-function millimeter-wavelength (THz-frequency) signal generation using OPO and DFG in a single cavity. In some embodiments, the OPO-DFG cavity includes an optical parametric oscillator (OPO) non-linear material that receives pump light IP having pump-light frequency and generates two different lower intermediate frequencies of light—an OPO-signal beam IS and a spatially/temporally overlapping OPO-idler beam II. A difference-frequency generator non-linear material then receives the two intermediate-frequency beams II and IS, and the DFG then generates a THz-frequency output signal that has a frequency equal to the difference between the two intermediate frequencies. In some embodiments, a single-piece crystal of non-linear material is used for both OPO and DFG functions.Type: ApplicationFiled: May 3, 2018Publication date: September 6, 2018Inventors: Yongdan Hu, Andrew Xing, Angus J.

Patent number: 8792978Abstract: Apparatus and method for optical- or optical-and-electrical stimulation of e.g., auditory nerve pathways, for example spiral ganglion in the cochlea or neurons in the cochlear nerve. Several configurations for guiding and directing the optical stimulation are disclosed. Several configurations for guiding and directing the electrical field (used in some embodiments, for sensitization) in and through the destination tissue to which the optical stimulation is directed are disclosed. In some embodiments, and array of IR VCSELs emit stimulation light, in particular to tissue in the cochlea for restoring hearing. In some embodiments, an electrical signal is also applied in a manner that reduces the amount of light in a pulse that is otherwise needed to elicit a NAP. In some embodiments, a heat dissipater is used to spread the heat generated by operation of the lasers and their circuits, to avoid heat damage to the tissue.Type: GrantFiled: September 24, 2010Date of Patent: July 29, 2014Assignee: Lockheed Martin CorporationInventors: Jonathon D.

Patent number: 6519157Abstract: Disclosed are systems and methods which utilize mounting members adapted to provide consistent compressive pressure with respect to strata of a laminated structure, such as the heat source, TEC, and heat absorbing layers of a TEC stack-up, throughout a range of operating temperatures. Preferably, mounting members of the present invention are adapted to provide uniform compressive pressure across a surface area, such as the heat transferring surfaces of a TEC, to thereby provide a sound structure which is relatively resistant to dynamic forces. Preferred embodiment mounting members are adapted to minimize the transfer of thermal energy therethrough, such as to substantially avoid a heat leak in a TEC stack-up configuration.Type: GrantFiled: October 23, 2001Date of Patent: February 11, 2003Assignee: nLight Photonics CorporationInventor: Andrew Xing
