A signal transmitting apparatus is provided that includes a light emitter and a circuit that controls the light emitter change in luminance in frequency to transmit a signal to a receiving apparatus. The method includes taking into account data types of data as a factor in determining a data layout for the binary file and for the executable’s dynamically allocated memory, wherein the data types include a floating-point data type and a non-floating-point data type. The invention improves current projectile technology with reduced assembly labor cost, the elimination of bow clearance issues, improved accuracy with the consistent production of the sliding stabilizer, easy replacement of the stabilizer in the field, and improved arrow storage.
