Abstract: A group or solo monitoring system and method for collision avoidance that uses a transceiver circuitry mounted on a vehicle. The circuitry can include a microprocessor, a memory having stored therein non-transitory instructions for programming the microprocessor, a visual indicator, an audio indicator, a user interface including a display screen and navigation buttons, an RF transceiver with antenna, and a power supply. Non-transitory instructions stored in memory configure and control the microprocessor to enable a user to enter data into the memory via the user interface via the display screen and navigation buttons. A vehicle group can be formed and a proximity perimeter created about the group. Visual and audio alerts are issued to avoid a collision in the event that a non-group vehicle has been detected as having penetrated the proximity perimeter and is closing in on at least one vehicle of the group.

Abstract: A keypad-based security system limits access to the ignition of a gas powered vehicle such as a golf or utility cart, to authorized operators having authorized ID codes. The security system, which is easily retrofit to existing vehicles, is interposed between the vehicle's ignition switch and the switch circuit of the vehicle. ID codes input by the operator using an on-board keypad are compared with a set of authorized ID codes stored in a memory, and a relay is energized to connect the ignition switch to the switch circuit with the energy source when the input ID code is verified as matching one of the authorized ID codes stored in the memory. The keypad uses only five keys to input a four digit ID code comprising any of the digits from 0 to 9.
