Title: Micro-lens array based light transmission screen
Inventor: WALKER DALE S
IPC: G03B21/62
Filed: 2004-06-02
Abstract: A light-transmission screen includes a diffusing element formed from a micro-lens array for projecting images in a viewing space. The screen generates images of improved quality by varying structural features of one or more lenses in the array so that light is directed in different directions and/or with different optical properties compared with other lenses in the array. The structural features which are varied include any one or more of size, shape, curvature, or spacing of the lenses in the array. As a result of these variations, the screen achieves wider viewing angles, improved screen resolution and gain, and a greater ability to reduce or eliminate aliasing or other artifacts in the generated images compared with conventional screens. A  method for making a light-transmission screen of this type preferably forms the micro-lens array using a stamping operation based on a master. By taking this approach, the screen is manufactured with fewer process steps and at less cost compared with conventional methods.

Patent CA-2531803-A1 (CA)
Inventor: WANG HANG
IPC: G01C17/38
Filed: 2004-07-21
Abstract: A tilt-compensated electronic compass can be realized by calculating rather than measuring Earth~s magnetic field component Z in a direction orthogonal to the two measurement axes of a 2-axis magnetic sensor. The orthogonal component Z can be calculated using a stored value for the Earth~s magnetic field strength applicable over a wide geographic region. The calculation also requires using measured field values from the 2-axis sensor. Once Z is known, and using input from a 2-axis tilt sensor, compensated orthogonal components X  and Y can be calculated by mathematically rotating the measured field strength values from a tilted 2-axis sensor back to the local horizontal plane. Thus, a very flat and compact tilt-compensated electronic compass is possible.
