Abstract: A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.

Abstract: Listing content is transmitted from a wireless mobile device to a server, where it is automatically posted in a listing database and made available on a network, such as the Internet, to third parties. The listing content may include both image data, captured by an integrated camera of the wireless mobile device, and text data, input by a user of the wireless mobile device. The wireless mobile device may provide an interface on its display to facilitate the capture of the listing content in discrete data components. After capture, the discrete data components for a single listing may be automatically associated together such that it is unnecessary for a user to manually associate them. The captured listing content may be automatically transmitted to the server in response to a single user selection received through the interface on the wireless mobile device.

Abstract: Systems for adjusting a position of an implanted medical device within a patient include an engagement tool configured to couple to the implanted medical device. The engagement tool adjusts the position of the medical device when coupled to the implanted medical device. Methods of adjusting a position of an implanted medical device within a patient include locating the implanted medical device, coupling an engagement tool to the medical device, and adjusting a position of the engagement tool to adjust the position of the medical device.

Abstract: An unmanned aerial vehicle having counterrotating ducted rotors that are driven by electric motors. The vehicle has a low weight and a small profile. The unmanned aerial vehicle is suitable for a number of different tasks, including control, surveillance and reconnaissance, communication, and other tasks without exposing personnel to dangerous situations. The vehicle is particularly suited for entering buildings and other enclosed structures and spaces such as caves. The unmanned aerial vehicle can also be equipped for potential offensive actions.

Abstract: Systems for providing stimulation with an implantable system control unit and for optimally positioning that system control unit include a system control unit configured to provide a stimulus to a patient with a member attached to the system control unit for pulling the system control unit into position within the patient. Methods of optimally positioning the implantable system control unit within a patient such that the system control unit is proximal to target tissue that is to be stimulated by the system control unit include threading a member through a patient's body using a needle, the member passing proximal to the target tissue and being attached to the system control unit, and pulling the system control unit into place with the member.
