Abstract: A method of unmanned aerial vehicle (UAV) flight includes providing horizontal thrust in-line with the direction of forward flight of the UAV using at least one electric motor, providing primary vertical lift for the UAV during the forward flight using a fixed and non-rotating wing, repositioning the at least one electric motor to provide vertical thrust during transition of the UAV to vertical flight for descent, landing the UAV on a surface using a vertical approach after the motor repositioning, and deploying an anchor to secure the UAV to a surface.

Abstract: A method of creating and duplicating recordings of a live performance for virtually immediate distribution to attendees of such live performance includes the pre-sale of such recordings before or during such performance. During the performance, audio analog signals are converted into digital audio signals and stored by a personal computer as a continuous digital recording. During the performance, the digital recording of such performance is sub-divided into tracks and a master disc is created of the sub-divided recording. One or more of such master discs are then inserted into one or more mass disc duplicators for rapidly producing copies thereof. The copies are then distributed to the attendees of the live performance who have purchased such copies in advance.

Abstract: A method of using a personal computer to create a digital recording of a substantially continuous audio performance sub-divided by tracks. Digital audio signals are provided to an input port of the personal computer. A software application program causes the computer screen to display “Record”, “Next”, and “Stop” buttons. Clicking the Record initiates recording and the creation of a first digital audio file. Clicking the Next button ends the current track and immediately starts the recording of a second track on a new digital audio file. Clicking the Stop button stops all recording and closes the currently-opened digital audio file. Created digital audio files corresponding to the created tracks are stored upon the computer's hard drive. Incoming digital audio signals are temporarily stored in RAM to create a time-delay buffer before being included within a digital audio file that is stored upon the hard drive.
