Abstract: A modification to conventional aircraft empennage design, which is also adaptable to all-wing aircraft. Vertical stabilizer/rudder assemblies are hinged such that actuator and lock mechanisms are able to vary the aircraft empennage configuration from one with fully functional conventional vertical stabilizer(s)/rudder(s) to one with no vertical stabilizer/rudder.

Abstract: An electronic wearable apparatus for providing bimodal stimulation to auditory system and somatosensory system of a user is disclosed herein. The apparatus includes a head-mounted wearable housing that is attached to an auditory system and a somatosensory system of the user. The apparatus also includes a wearable audio output structure configured to apply audio stimulation to the auditory system of the user. The apparatus further includes a wearable transdermal electrical transducer configured to apply a somatosensory stimulation signal to the somatosensory system of the user through a transdermal electrical contact which is in direct contact with a portion of surface structure of the user for stimulating the somatosensory system. The apparatus further includes an electronic control processor that is connected to the audio output structure and the transdermal electrical transducer and configured to synchronize the bimodal stimulations to create a nerve stimulation to improve user's body.

Abstract: A method for interconnecting two Bluetooth type systems with two sets of microphones and speakers, wherein microphone M1 and speaker(s) S1 are paired with a first computing device while microphone M2 and speaker(s) S2 are paired with a second computing device; however, microphone M1 and speaker(s) S2 share a first housing, while microphone M2 and speaker(s) S1 share a second housing.

Abstract: My invention is an ankle reinforcing device for the prevention of medial and/or lateral ankle injuries such as sprains or breaks. The object of the invention is to provide an inexpensive but highly effective device which will allow free and unhampered movement of the wearer's foot while engaged in athletic events or other physical activity but will prevent movement in such a direction and to such an extent that would result in spraining or breaking an ankle. The ankle reinforcing device is constructed from an underlying member which covers all or part of the foot and part of the leg above the ankle, reinforcing members attached to or integral with the underlying member, and means to securely attach the device to the wearer. The reinforcing members are arranged in a pattern to prevent excessive movement of the ankle in the medial and/or lateral directions, while allowing free up and down movement of the foot.
