Publication number: 20150124415Abstract: Embodiments of the present application relate generally to personal electronics, portable electronics, wearable electronics, and more specifically to a structure and method for a protective covering for a wearable device. Interior and exterior structures of the wearable device are configured to be flexed into a configuration and to retain the configuration after the flexing. Interior structure may include a first flexible substrate having a first relaxation structure and a second flexible substrate having a second relaxation structure. Components or other structures may be connected with the first and/or second flexible substrates. The first and second relaxation structures may be positioned relative to each other to define a flexure point. At least one flexible and electrically non-conductive cover, that may undergo shirking, may conformally cover at least a portion of the interior structure. A flexible overmolding may be formed over the cover and may comprise the exterior structure.Type: ApplicationFiled: November 6, 2013Publication date: May 7, 2015Applicant: AliphComInventors: Dileep Goyal, Andrew Dawn, William Maginn, Hari Chakravarthula

Patent number: 8913005Abstract: A display device can be used with an ergonomic sensor comprising an imaging device interfaced to processing hardware to obtain and analyze image data depicting a user of the display device. The ergonomic sensor can be preconfigured with data indicating ergonomic uses of the display device so that the image of the user can be analyzed with minimal or no user calibration or setup. Instead, the ergonomic sensor can analyze the image data to provide real-time feedback, such as warnings or suggestions when the user's behavior falls outside an ergonomic use range for the display device. In some implementations, the ergonomic sensor is integrated with the display device, though in other implementations a separate element or preexisting imaging device can be used.Type: GrantFiled: April 8, 2011Date of Patent: December 16, 2014Assignee: Fotonation LimitedInventors: Avinash Uppuluri, Celia Morales, Hari Chakravarthula, Sumat Mehra, Tomaso Paoletti

Patent number: 8630658Abstract: A cellular telephone is provided with a wearable housing, desirably in a form which can be concealed in the user's clothing, wallet, or other place. The housing may be devoid of switches or buttons for controlling the cellular telephone, and control inputs can be provided through free space communications such as a short-range radio link. A module for use in portable communications devices includes chips superposed on one another on a stack, and incorporates an interposer for facilitating connections between the chips.Type: GrantFiled: April 9, 2012Date of Patent: January 14, 2014Assignee: Tessera, Inc.Inventors: Stuart E.

Patent number: 8417759Abstract: A method and apparatus for efficiently performing digital signal processing is provided. In one embodiment, kernel matrix computations are simplified by grouping similar kernel coefficients together. Each coefficient group contains only coefficients having the same value. At least one of the coefficient groups has at least two coefficients. Techniques are disclosed herein to efficiently apply successive first order difference operations to a data signal. The techniques allow for a low gate count. In particular, the techniques allow for a reduction of the number of multipliers without increasing clock frequency, in an embodiment. The techniques update pixels of a data signal at a rate of two clock cycles per each pixel, in an embodiment. The techniques allow hardware that is used to process a first pixel to be re-used to start the processing of a second pixel while the first pixel is still being processed.Type: GrantFiled: November 13, 2007Date of Patent: April 9, 2013Assignee: DigitalOptics Corporation Europe LimitedInventors: Hari Chakravarthula, Christopher Loo, Jose Mendez

Publication number: 20130057573Abstract: An electronic display is provided that can include any number of features. In some embodiments, the display includes sensors, such as a camera, configured to detect a user parameter of a user positioned before the display. The user parameter can be, for example, an age of the user, a distance of the user from the screen, a head angle of the user, a time the user has been positioned before the display, or an ambient light level. The display can include a processor configured to adjust a user preference or display an indicator to the user based on the detected user parameter.Type: ApplicationFiled: November 11, 2011Publication date: March 7, 2013Applicant: DigitalOptics Corporation Europe LimitedInventors: Hari Chakravarthula, Tomaso Paoletti, Avinash Uppuluri

Publication number: 20090077359Abstract: An architecture for heterogeneous data processing which reuses the same hardware to process different data in different manners is disclosed. The different processing has a substantial similarity; such as performing different variations of a computation. For example, the computation may involve the same mathematical operations but use different constants or coefficients, or performing similar arithmetic operations that can be switched such as addition and subtraction, or performing arithmetic operations in different orders, etc. The different processing might be applying different convolution kernels depending on the pixel color. The differences between the kernels could include different kernel sizes, different coefficient locations, and different coefficient values. The same hardware is re-used for all of the similar computations, under the control of external control logic that allows hardware re-use.Type: ApplicationFiled: November 27, 2007Publication date: March 19, 2009Inventors: Hari Chakravarthula, Christopher J.
