Abstract: A method, computer program product and system are provided for preloading debug information based on the presence of incremental source code files. Based on parsed input parameters to a source code debugger, a source code repository and a local storage area are searched for an incremental file. In response to the incremental file being located, a preload indicator in the incremental file, which is a source code file, is set. Based on the preload indicator being set, debug symbol data from the incremental file is merged to a preload symbol list. In response to receiving a command to examine the debug symbol data from the incremental file, the preload symbol list is searched for the requested debug symbol data.

Abstract: The present invention uses the concave hybrid architecture to form a wide angle projection lens with large numerical aperture. The wide angle projection lens includes a refraction system and a reflection system, wherein the refraction system includes a first lenses group containing a plurality of spherical lenses and at least one spherical lenses, and a second lenses group containing at least two aspheric lenses and at least one spherical lens, and the at least one spherical lens is configured between any two of the at least two aspheric lenses. The present invention is beneficial in reducing the wide angle projection lens in size and is able to effectively overcome the problem in low geometric efficiency, and enable the ultra-short focus projector have compact and portable advantages.

Abstract: The image projection and capture apparatus for projecting an image beam to display an image on a screen and sensing a sensing beam from the image on the screen, the image projection and capture apparatus includes a light source, a light valve, a projection lens, an image capture lens, a dichroic unit, and an image sensor. The light source provides an illumination beam. The light valve is capable of converting the illumination beam to the image beam. The projection lens has a first optical axis. The image capture lens has a second optical axis. The first optical axis and the second optical axis are collinear. The dichroic unit is disposed between the projection lens and the image capture lens. The image sensor is disposed on a light path of the sensing beam.
