Abstract: A device for removing cobwebs comprising a handle (6) housing electrical storage cells (16), and a motor (14); said motor (14) being drivably connected to a length of rod (8) which when made to come in contact with cobwebs while being spun by the energized motor (14) causes cobwebs (30) to stick to and get tightly wound around said rod resulting in the effective removal and disposal of the cobwebs.

Abstract: An electronic posture position sensor device for alerting the user whenever an incorrect posture is assumed. The posture position sensor includes an electrical circuit that includes, a power means, a switch assembly, an electronic timer capable of being set at predetermined cycles, and an alerting means. The switch assembly comprises a first conducting pendulum and two sensor terminals attached, respectively, to second and third selectively positionable conducting pendulums. The second and third pendulums have a clamping means which allow the user to manually position the second and third pendulums for different sitting positions. When an incorrect posture is assumed, the switch assembly is opened which allows current to flow from the power means through the circuit to the timer. When the predetermined timer cycle elapses, the current causes the alert means to alert the user when sitting in an incorrect sitting position.

Abstract: By providing a bicycle with a one-way brake coupled between the front wheel and the frame of the bicycle, the one-way brake being configured to permit only forward rotation of the front wheel, dangerous reverse rotation of the front wheel, which accompanies turning abruptly without adequate forward momentum and/or with an incorrect leaning angle, is avoided and the precipitous falling and serious injury to the rider which normally accompanies reverse rotation of the front wheel under these conditions is prevented.
