Patent number: 9503666Abstract: An image sensor includes readout circuits coupled to read out integrated light signals from pixels via bitlines respectively. Each readout circuit includes a correlated double sampling (CDS) circuit, followed by an analog-to-digital converter (ADC). At least two pixels of a row share a bitline and an associated readout circuit. The ADC operates concurrently with the CDS circuit, such that their operating periods are substantially overlapped with each other.Type: GrantFiled: January 22, 2015Date of Patent: November 22, 2016Assignee: HIMAX IMAGING LIMITEDInventors: Ping-Hung Yin, Jia-Shyang Wang, Satya Narayan Mishra, Amit Mittra, Ray-Chi Chang

Patent number: 9461978Abstract: A method and system for role based access control for a plurality of users in a heterogeneous enterprise environment, comprising: establishing a functional relationship between a plurality of provisioning unit using a provision unit module. The users are mapped with the provisioning unit based on attributes of the users. Events are captured via the provision unit module. The users needed to be re-mapped are determined upon the event completion. Application role defined in context of an application embedded in an application registry module is mapped with the provisioning unit. Call back service is executed for the re-mapped users having entitlement associated with each of the application stored in a roles registry module. An application role is determined and defined for a new user for the plurality of the application enabling managing of the role based access control.Type: GrantFiled: September 20, 2013Date of Patent: October 4, 2016Assignee: Tata Consultancy Services LimitedInventors: Satya Narayan Mishra, Ashesh Misra

Patent number: 9143708Abstract: A pixel array comprises at least one long exposure pixel, short exposure pixel, and a control circuit. The long exposure pixel comprises a first photodiode to generate charges, a first image signal generating module for generating a first image sensing signal; and a first transfer switch device for passing the charges to the first image signal generating module via a first transfer control signal. The control circuit sets the first transfer control signal to be a first predetermined control voltage when the long exposure pixel is in an long exposure phase, and then sets the first transfer control signal to be a second predetermined control voltage when the short exposure pixel is in a short exposure phase.Type: GrantFiled: December 11, 2013Date of Patent: September 22, 2015Assignee: Himax Imaging, Inc.Inventors: Ping-Hung Yin, Amit Mittra, Kaveh Moazzami, Satya Narayan Mishra

Publication number: 20150170329Abstract: A signal processing apparatus includes a correlated double sampling unit and a processing unit. The correlated double sampling unit is arranged for receiving a reset signal and a data signal, obtaining a reset level and a first data level corresponding to the reset signal and the data signal, respectively, and outputting an output signal according to a level difference between the reset level and the first data level. The processing unit is coupled to the correlated double sampling unit, and is arranged for receiving a second data level of the data signal and a predetermined level, and comparing the second data level with the predetermined level to generate a detection result indicative of quality of the level difference.Type: ApplicationFiled: February 24, 2015Publication date: June 18, 2015Inventors: Ping-Hung Yin, Kaveh Moazzami, Satya Narayan Mishra, Amit Mittra
