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.

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.

This invention relates to the formation of three-dimensional objects on substantially layer-by-layer basis with enhanced resolution. The invention utilizes a unique offset printhead containing groups of jets to selectively deposit a hot-melt material.

Non-linear printhead assembly

Rapid prototyping modeling typically operates by utilizing an ink jet to lay down a thin surface of material as a liquid on a part platform. The material solidifies into a three dimensional object. Computer programs determine the shape of the object, the arrangement of objects and the sequence of objects being built to protect parts of the planarizer roller and planarizer blade of a rapid prototyping machine from erosion.

Method and apparatus for selective deposition modeling

A method, system and apparatus for variably controlling the temperature in a selective deposition modeling environment. The temperature of the formed portion of the three-dimensional object is detected. A gas is forced onto a surface of the formed portion of the three-dimensional object. The forced gas has a characteristic, such as temperature and quantity, that is variably controlled based on the detected temperature of the formed portion of the three-dimensional object.

Techniques for printing raster lines in a selective deposition modeling (SDM) system. Raster lines may be printed using different numbers of jets in each group in different passes. Moreover, full and partial head randomization is available. Selected raster lines are printed in one direction, although the print head prints in two directions. Furthermore, raster lines printing may be interlaced, and deposition order may be changed between layers.
