Abstract: A device placed or installed in a user's vehicle or other venue and operative to sense the opening and/or closing of a venue door and to be in wireless communication with a user's cell phone. When a user is entering, for example, a vehicle, the device senses door opening and/or closing and is triggered to search for the user's phone. Upon detection of that phone, the device provides an alert to the user that the phone is present. If the phone is not present, the device senses such absence and provides an alert that the phone is not present. Similar alerts are provided by the device when the user exits the vehicle. The device is also useable in other venues having a door. The system can also be used in devices other than cell phones that have similar communications capability to communicate with the system described herein.

Abstract: The present invention provides a body worn or body connected peripheral vision notification method and system to provide a visual indication to the person of limb or body movement or position. The system and method make use of a simple device which typically can be worn on the wrist or ankle of the user and which provides a visual warning or notification to the user while the user is engaged in various activities or actions. As one example, the invention provides a visual warning that the user may be about to touch his or her face with the hand. Such a warning can cause the user to refrain from touching the face. As another example, a wrist worn device in accordance with the invention can signal to a user the correct positioning of arms and hands for training in hitting a baseball. As a further example, an ankle worn device can signal foot position to monitor a person's stride.

Abstract: An apparatus for use with a telephone including, in one embodiment, a detector for detecting when the telephone is in an off-hook condition and disconnect circuit for eliminating the off-hook condition when the off-hook condition is caused by the telephone so that phone calls may be received by the line. An alarm responsive to the detector produces a warning of the off-hook condition if another phone on the line is off hook.

Abstract: An electronic game that includes a main body that consists of four panels assembled to form a four-sided pyramid having four vertexes. Each vertex serves as a node for supporting a light which may illuminate a plurality of different colors. Digital circuitry defines a color state vector at each node by illuminating one or none of the colors. Control circuitry connected to the digital circuitry is used for altering the color state of at least one of the lights as the tetrahedron is rotated. In one game, the color of the node brought to the top position changes in the color change pattern established by the color state vector. A player rotates the tetrahedron in an effort to figure out the pattern of color changes. Once the pattern is deciphered, the player makes additional rotations to achieve an object of the game such as having each vertex of the tetrahedron lighted the same color.
