Patent number: 9515789Abstract: A Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system for inter-device communication is described. Information data from each neuromorphic chip is coded and modulated, on the basis of destination, into different channels. The parallel signals in different channels are sent serially using TDM to a central router. After signal grouping by a central switching controller, each group of signals may be delivered to corresponding transmitter in the central router for transmission to a corresponding receiver in the neuromorphic chip using TDM.Type: GrantFiled: February 27, 2013Date of Patent: December 6, 2016Assignee: HRL Laboratories, LLCInventors: Deying Zhang, Narayan Srinivasa

Patent number: 9362763Abstract: A wireless charging circuit and an abnormal state protection circuit thereof is provided in the present invention. The wireless charging circuit includes a power converter, a resonant circuit and an abnormal state protection circuit. The power converter receives an input voltage for outputting a PWM (pulse width modulation) signal. The input terminal of the resonant circuit receives the PWM signal. The common voltage terminal of the resonant circuit is coupled to a common voltage. The abnormal state protection circuit includes a DC sampling circuit and a control circuit. The DC sampling circuit is coupled to the resonant terminal of the resonant circuit for sampling the DC component of the voltage of the resonant terminal to obtain a DC voltage.

Patent number: 8861893Abstract: A method and apparatus for processing images. A portion of a selected image in which a moving object is present is identified. The selected image is one of a sequence of images. Pixels in a region of interest are identified in the selected image. First values are identified for a first portion of the pixels using the images and first transformations. The first portion of the pixels corresponds to the background in the selected image. A first transformation is configured to align features of the background between one image in the images and the selected image. Second values are identified for a second portion of the pixels using the images and second transformations. The second portion of the pixels corresponds to the moving object in the selected image. A second transformation is configured to align features of the moving object between one image in the images and the selected image.Type: GrantFiled: September 27, 2011Date of Patent: October 14, 2014Assignee: The Boeing CompanyInventors: Yang Chen, David R.
