Abstract: A method and apparatus for determining pitch and yaw of an elongated interface object as it interacts with a touchscreen surface. A touch image is received, and this touch image has at least a first area that corresponds to an area of the touchscreen that has an elongated interface object positioned at least proximate to it. The elongated interface object has a pitch and a yaw with respect to the touchscreen surface. A first transformation is performed to obtain a first transformation image of the touch image, and a second transformation is performed to obtain a second transformation image of the touch image. The first transformation differs from the second transformation. The yaw is determined for the elongated interface object based on both the first and second transformation images. The pitch is determined based on at least one of the first and second transformation images.

Abstract: Original program code of an app of a mobile operating system is protected by splitting the original program code into several program code segments and encrypting the program code segments. The encrypted program code segments are received in separate files in a mobile computing device, where the encrypted program code segments are loaded in memory of the mobile computing device. The encrypted program code segments are decrypted, and the resulting decrypted program code segments are stored in non-contiguous blocks of memory. The decrypted program code segments are parsed for loading and execution in the mobile computing device, such as by a Dalvik process virtual machine of an ANDROID operating system of the mobile computing device.

Abstract: The present invention features, inter alia, constructs for the delivery of therapeutic and diagnostic agents to a patient. The constructs can include a nanoparticle, a targeting agent that specifically binds a targeted tissue or cell, a therapeutic moiety, and a hydrogel. The constructs can be used in the treatment and diagnosis of bowel diseases, including inflammatory bowel disease (IBD) and colon cancer. In one embodiment, the therapeutic agent is a nucleic acid that mediates RNA inhibition (RNAi), and the invention is directed to treatments for IBD that combine the positive aspects of such agents {e.g., siRNAs) with the safety of a biodegradable polymeric delivery system to facilitate specific targeting of colonic tissues and cells. As the constructs can be formulated for oral administration, they are well tolerated and offer advantages with regard to patient compliance.
