Abstract: An improved electric scooter provides a speed range controller for selection between a plurality of speed ranges. The speed range controller includes a switch for switching between a first switch position wherein a fixed resistor is placed in series with the potentiometer and a second switch position wherein the potentiometer is the only resistance connected to the motor controller. In the first switch position the maximum control voltage sensed by the motor controller is reduced by the presence of the fixed resistor to a value less than the reference voltage, and the maximum speed of the DC motor within the first speed range is less than the maximum speed dictated by the battery voltage and the DC motor specifications. In the second switch position, the maximum control voltage sensed by the motor controller is the reference voltage, and the maximum speed of the DC motor is dictated by the battery voltage and the DC motor specifications.

Abstract: A computer-implemented method of translating an assembler program into a high-level language computer program is provided. The method includes receiving each line of the assembler program, parsing individual fields in each assembler program line, including an absolute line number and an opcode for an assembler instruction. Each assembler program line is then stored into a data structure such that each line is accessible and each field in each line is accessible, and the numeric opcode of each assembler program line is parsed into individual digits. Alternatively, the symbolic opcode and operands may be decoded to produce a more human readable and maintainable output. For each assembler program line, a decision tree is traversed in response to the value of each opcode digit to identify the corresponding assembler instruction. The assembler instruction is then translated to an equivalent set of code in the high-level computer language.
