Filed:

May 6, 2010

Appl. No.:

12/775339

Inventors:

Sylvain M. Colin - San Diego CA, US
Jun Young Park - San Diego CA, US
Marzio Pedrali Noy - San Diego CA, US

Assignee:

Qualcomm Incorporated - San Diego CA

International Classification:

H03K 3/02

US Classification:

331143, 331111

Abstract:

An oscillator is disclosed. The oscillator includes a first capacitor. The oscillator also includes a second capacitor. The oscillator further includes a first current source. The oscillator also includes a second current source. The oscillator further includes a comparator that has a first input and a second input. The oscillator also includes a reference node. The oscillator further includes a controller that is configured to selectively couple the first current source to the first capacitor and the second current source to the reference node during a first time period.

Abstract:

Methods, apparatus, devices, and systems for three-dimensional (3D) displaying objects are provided. In one aspect, a method includes obtaining data including respective primitive data for primitives corresponding to an object, determining an electromagnetic (EM) field contribution to each element of a display for each of the primitives by calculating an EM field propagation from the primitive to the element, generating a sum of the EM field contributions from the primitives for each of the elements, transmitting to each of the elements a respective control signal for modulating at least one property of the element based on the sum of the EM field contributions, and transmitting a timing control signal to an illuminator to activate the illuminator to illuminate light on the display, such that the light is caused by the modulated elements of the display to form a volumetric light field corresponding to the object.
