Abstract: A handheld controller configured to be held by a user's hand. The handheld controller comprising a main body, and a handle extending from the main body, wherein the handle has a palm side and a finger side. A control button is positioned on the main body or handle, and a detection sensor is on the handle. The detection sensor is positioned to detect the presence of the finger or palm of a user's hand engaging the handle. The detection sensor can be a capacitive touch sensor, a proximity sensor or other detection sensor operative to detect the touch or spatial presence of the user's hand or fingers.

Abstract: Building a kernel hook module (KHM) on a build machine in an automated manner uses a script file to control the process. A user requests a KHM for a particular Linux kernel of a Linux distribution. The build machine is rebooted if necessary to run the target Linux distribution. Kernel source files for the Linux distribution are loaded and installed on the build machine. Various parameters are set and source code representing the functionality of the KHM (or that of a related software product) are loaded onto the build machine. The KHM is then built automatically under direction of the script file. A control machine receives the user request for a particular KHM over the Internet and directs operation of the build machine. A test machine tests the KHM once built. The KHM works in conjunction with anti-virus software or other software.
