Abstract: The camouflage technique described herein introduces programmed configuration inputs to Micro Netlists, creating Programmable Micro Netlists (PMNLs). PMNLs are a group of camouflaged and non-camouflaged cells that may be configured to perform one of several possible logic functions. They retain all the protective properties of non-programmable MNLs, but also allow for secure post-manufacture configuration of their aggregate logic function.

Abstract: A method and apparatus for camouflaging an application specific integrated circuit (ASIC), wherein the ASIC comprises a plurality of interconnected functional logic is disclosed. The method adds functionally inert elements to the logical description or provides alternative definitions of standard logical cells to make it difficult for reverse engineering programs to be used to discover the circuit's function. Additionally, post processing may be performed on GDS layers to provide a realistic fill of the empty space so as to resemble structural elements found in a functional circuit.

In one embodiment, the camouflaged application specific integrated circuit (ASIC), comprises a plurality of interconnected functional logic cells that together perform one or more ASIC logical functions, wherein the functional logic cells comprise a camouflage cell including: a source region of a first conductivity type, a drain region of the first conductivity type, and a camouflage region of a second conductivity type disposed between the source region and the drain region. The camouflage region renders the camouflage cell always off in a first camouflage cell configuration and always on in a second camouflage cell configuration having a planar layout substantially indistinguishable from the first configuration.

Abstract: For an augmented reality (AR) content creation system having a marker database, when a user requests this system to use a first sub-image of an image to update the marker database, this system computes a suitability score of the first sub-image for rating feature richness of the first sub-image and uniqueness thereof against existing markers in the marker database. When the suitability score is less than a threshold value, a second sub-image of the image having a suitability score not less than the threshold value and completely containing the first sub-image is searched. Then the second sub-image, the suitability score thereof and the suitability score of the first sub-image are substantially-immediately presented to the user for real-time suggesting the user to use the second sub-image instead of the first sub-image as a new marker in updating the marker database to increase feature richness or uniqueness of the new marker.

Abstract: The present invention relates to an optical communication system and an optical transmission device. By changing the ratio between the first segment and the segment or/and the amplitude of the second segment, the digital signal is modulated and transmitted in the form of an optical signal. Then a solar panel, which is used as the receiver for the optical signal, can receive the optical signal and give directly the one or more digital signal without demodulation. Thereby, the costs of using a solar panel as the optical receiver may be reduced and the transmission rate may be enhanced.
