Filed:

Mar 25, 2005

Appl. No.:

11/090432

Inventors:

Steve Schell - Arcadia CA, US
Robert Witman - Pasadena CA, US
Joe Brown - Valencia CA, US

Assignee:

Evolution Robotics, Inc. - Pasadena CA

International Classification:

H01L 31/113

US Classification:

257434, 257E31122, 257680, 257681, 3482301, 348345, 2502035

Abstract:

An apparatus and method of integrating optics into an IC package is for detecting light from at least one light source is disclosed. The apparatus has a housing, which has a predetermined spectral transmittance. A sensor is positioned within the housing. An opaque mask is applied to the housing, where the opaque mask has a hole aligned with the sensor such that the light's centroid is detected by the sensor. In one embodiment, the apparatus further comprises a substrate for positioning and stabilizing the sensor in the housing, an analog filter and amplification module (“AFA”) for filtering and amplifying signals from the sensor and generating a second signal, and a digital signal processor (“DSP”) for generating a coordinate system by extracting frequency components from the AFA output signal.

International Classification:

H03F003/45

US Classification:

25021400A

Abstract:

A circuit system for estimating position and orientation of a mobile object based on lights from a plurality of external light sources. The circuit comprises a position-sensitive light sensor for detecting the light sources and generating a first signal, an analog filter and amplification module (“AFA”) for filtering and amplifying the first signal and generating a second signal, a digital signal processor (“DSP”) for generating a coordinate system by extracting frequency components from the second signal.

Assignee:

Evolution Robotics, Inc. - Pasadena CA

International Classification:

G01B011/14

US Classification:

356614000

Abstract:

A sensing device and method of estimating the position and orientation of an object with respect to a local or a global coordinate system is disclosed. The method and device include one or more optical sensor, a signal processing circuitry and a signal processing algorithm to determine the position and orientation. A sensor is positioned within the housing. At least one of the optical sensors used in the method and system outputs information based at least in part on the detection of the signal of one or more light sources.
