Abstract: A method and apparatus for improving the accuracy and usability of alphanumeric keypads and control functions on touch-screen devices by employing multi-function buttons and the actuation of multiple buttons in sequence by sliding a finger across the touch-screen. Potential applications include cell phones, smart phones, calculators, handheld scanners, gaming systems, remote controls, GPS navigation devices, and ultra small laptop computers. A first embodiment is an alphanumeric keypad for a touch-screen smart phone. In this embodiment, a modified QWERTY keypad layout is employed to allow selection of the most frequently used letters by touching the display and the selection of less frequently used letters by sliding a finger on the display. In this first embodiment, multiple letters can be entered in sequence by sliding from one button to either an adjacent or non-adjacent button. A second embodiment is a numeric keypad for entering phone numbers on a touch-screen phone.

Abstract: A motorized stroller includes a first frame member adapted to support a seat for placement of an infant and a pair of wheels for movement of the first frame member along the ground. The motorized stroller also includes a motorized wheel assembly having a motorized wheel frame adapted for attachment to the first frame member, a pair of wheels coupled thereto, a motor for driving at least one of the wheels attached to the motorized wheel frame, and a gear reduction unit operatively coupling the motor to at least one of the wheels of the motorized wheel frame. When the motor operates, power is provided from the motor by the gear reduction unit to at least one of the wheels of the motorized wheel frame which enables the stroller to move in one of a forward and reverse direction without power for movement being provided by a user. The motorized wheel assembly is capable of being disengaged such that the motorized stroller can be manually pushed by a user and therefore used in a conventional fashion.
