Abstract: A wearable digital video camera (10) is equipped with wireless connection protocol and global navigation and location positioning system technology to provide remote image acquisition control and viewing. The Bluetooth® packet-based open wireless technology standard protocol (400) is preferred for use in providing control signals or streaming data to the digital video camera and for accessing image content stored on or streaming from the digital video camera. The GPS technology (402) is preferred for use in tracking of the location of the digital video camera as it records image information. A rotating mount (300) with a locking member (330) on the camera housing (22) allows adjustment of the pointing angle of the wearable digital video camera when it is attached to a mounting surface.

Abstract: An integrated hands-free, point of view, action-sports, digital video camera (or camcorder) (10) includes: a rotary horizon adjustment controller (14) for adjusting the orientation of a horizontal image plane (16) recorded by an image sensor with respect to the orientation of a camera housing (22); a laser alignment system with laser sources (48) capable of projecting light to define a horizontal projection axis (52) that is coordinated with orientation of the horizontal image plane (16); a manually operable switch (80), which covers a microphone (90) whenever the switch (80) is in the OFF position, for controlling video data capture; and a “quick-release” mounting system (120) that retains a desired orientation of the camera (10).

Abstract: A toothbrush in which the bristles define a surface across the width of the handle having a convex portion along the midline of the handle and concave portions on either side of the convex portion, thereby to conform to the corresponding complementary surface portions of the molars. In a preferred embodiment the bristles are longest along the center of the handle and shortest along the sides of the handle. To facilitate gripping, the handle has a cross-section that is concave along the front of the handle and of uniform thickness across the width of the handle. To minimize displacement of the handle when brushing various portions of the teeth, the handle is rearwardly curved along the lower portion thereof and is forwardly curved along the upper portion thereof.
