  • Publication number: 20140103181
    Abstract: A system and method for universally mounting a user's imaging solution(s). The universal mounting solution (sometimes referred to herein as the Velocity Clip) is a universal video mounting system for smartphones and digital cameras with video capabilities that turns them into a point of view camera. The Velocity Clip allows the user to attach their smartphone video device securely to their head, chest, or any hard or mobile surface with a gear mount by using a versatile mounting system (e.g., a set of straps or the like).

  • Patent number: 7211907
    Abstract: A programmable power system may be used to control the supply of power from a battery to protect the battery from accidental discharge and excessive wear. A programmable power control unit may be connected between a battery and one or more battery operated devices. Typically, the battery is installed in a vehicle (e.g., a motor vehicle, an airplane, or a watercraft) although the unit may be used with any battery powered system. The programmable power control unit may be used to control the supply of power from the battery to one or more auxiliary devices, such as, for example, a two-way CB and ham radio, an AM/FM radio, a music player, a PDA, a TV, a DVD player, a cellular phone, a radar device, a GPS device, a data terminal, a display, and a computer. The programmable power control unit automatically turns the devices on in response to a predetermined battery operating condition, and turns the devices off after a predetermined time period in response a non operating condition.

  • Patent number: 5563452
    Abstract: The present invention relates to a control unit for vehicle-borne electrical equipment, that is, to a control unit for turning on vehicle-borne electrical equipment either periodically or at a predetermined or preset time, providing power to the equipment for a further predetermined or preset time, and then suspending supply of power to the electrical equipment. These functions are accomplished by a programmable timer power switch (PTPS) unit in combination with further control circuitry, each of the latter two elements having its own timer units or circuity.

  • Patent number: 5272386
    Abstract: A programmable timer power switch unit with emergency override reset for use with a battery includes a power switch which receives power from the battery and switches the power to equipment. The unit also has a plurality of voltage detectors connected to the battery to detect a plurality of voltages and a vibration-pressure detector which detects any movement of the motor. There is a timer-control logic which is connected to the components and disables the power switch when voltage problems are detected. The unit further includes a programmable delay switch. The purpose of this switch is to allow the equipment to run during a pre-selected time. Also, there is an auto/manual override switch for overriding the timer-control logic and providing a short delay time prior to disconnecting the unit in order to protect any memory intensive electronic equipment from intermittent drop-outs such as when the engine is started.

  • Patent number: 4950913
    Abstract: A programmable timer power switch unit for use with a battery includes a power switch receives power from the battery and switches the power to equipment. The unit also has a charge-discharge detector connected to the battery to detect a potential charge of the battery and a vibration-pressure detector which detects any movement of or sounds from the motor. There is a timer-control logic which is connected to the components and disables the power switch when any problems are detected. The unit further includes a programmable delay switch. The purpose of this switch is to allow the equipment to run during a pre-selected item. Also, there is a manual override switch for overriding the timer-control logic when necessary.
