摘要： A vertical light source package uses leadframes with leads that extend in the same predefined direction. The leadframes are at least partially positioned in a structural body of the vertical light source package. The vertical light source package includes a light emitting device, such as a vertical-cavity surface-emitting laser, that is situated on one of the leadframes and electrically connected to the other leadframe.

摘要： A pointing device having an illumination system, camera system, and positioning mechanism is disclosed. The illumination system illuminates a surface below a transparent plate having a constant thickness. The camera system records images of the illuminated surface. The positioning mechanism adjusts the relative position of the illumination with respect to the camera system. The relative position is determined by the constant thickness. The positioning mechanism has a first position corresponding to a predetermined value for the constant thickness and a second position corresponding to the constant thickness being zero. The positioning mechanism is operable by a user of the pointing device to compensate for different thicknesses of transparent plates.

摘要： An optical navigation device that regulates the brightness of an adjustable light source, and a method thereof, are described. Light from the light source is emitted onto a surface and reflected from the surface to a sensor. The light received by the sensor is used to measure movement of the optical navigation device relative to the surface. A light-sensitive device also receives light from the light source. The brightness of the light source can be adjusted according to the amount of light received at the light-sensitive device.
