Abstract: A rapid charging device for charging an internal battery of an electronic device. The rapid charging device includes one or more charging stations. Each charging station includes a charging platform that includes multiple different charging tips. Each of the different charging tips can be used to charge a different type of electronic device. A support cradle in the charging station provides support for the electronic device when the electronic device is being charged. The support cradle is movable relative to the charging platform to position the electronic device above the desired charging tip. The rapid charging device includes internal power supply circuit that regulates the voltage supplied to each of the electronic devices and supplies current above the maximum charging current for the electronic device such that the electronic device can charge at its most rapid rate.

Abstract: A GPS speedometer comprising: a housing; a circuit board located in the housing; a microprocessor located on the circuit board; a GPS module located on the circuit and in signal communication with the micro-processor; a GPS antenna located on the circuit board and in signal communication with GPS module; and a readable speedometer display located on the housing and in signal communication with the microprocessor, where the readable speedometer display is configured to display the current speed of the vessel or vehicle calculated by the microprocessor based on data from a global positioning system.

Abstract: A peristaltic pump with a removable pump race module has guiding channels for receiving at least a portion of a flexible fluid-carrying tubing and an adjusting device for displacing a flexible inner portion of the removable pump race module to change the compression on the fluid-carrying tubing. The arrangement of the various elements makes it particularly suitable in configurations where compactness and convenience are important considerations.
