Abstract: A method and apparatus for reducing the drag of a motor vehicle includes a mechanism for diverting air attached to a front portion of the vehicle and a vacuum plate having openings therein for attachment to a back of the vehicle. Mechanisms for diverting air include a cover piece encasing a front portion of the vehicle, one or more separation panels attached to the front of the vehicle, and one or more tubular members attached to the front of the vehicle. Both the cover piece and vacuum plate are attached to the vehicle so that a space is maintained between the vehicle and the cover piece and vacuum plate, respectively.

Abstract: A manually operated animal training device that can be combined with proven and traditional training methods includes means for providing a fluid spray to deter unwanted animal behavior.

Abstract: A battery operated device for indoor use in deterring domesticated animals from approaching or climbing on an object. The device incorporates a sensor which senses the approach of the animal and relays a signal to a motor, thus activating the pump to deliver the fluid contained within a reservoir to a mist sprayer. The device delivers the fluid in a misting manner coming in contact with the approaching animal, so as to not damage any indoor furnishings. The sensing mechanism is of the type capable of detecting the presence of a magnetic field, of detecting the animal through the elevated temperature of the animal or the detecting the approach of the animal within a certain proximity to the sensor. The device remains undetectable to the approaching animal and thus the animal is unable to associate the device with the offensive spray of fluid.

Abstract: A hang glider attitude recovery device that may be rapidly deployed with a minimum of pilot action comprises a drag element having an effective point of attachment rigidly spaced above the point from which the pilot is suspended, and a mechanism for activating the drag element at a point clear of upper structural members. The separation between the attachment point and suspension point provides a lever arm which is responsible for the operation of the device. When the hang glider is in a position where the lever arm is inclined from the vertical (hang glider out of attitude), activation of the drag element provides an upward force at the upper end of the lever arm, which force produces a moment that tends to bring the suspension point back into a position under the attachment point. In the preferred embodiment, the drag element comprises a small parachute stowed within the tubular king post.
