Abstract: An apparatus for prescription processing configured to perform: receiving a first to sixth values; determining a seventh to ninth values from a first function, the first to sixth values; determining a tenth to twelfth values from a second function, the first to sixth values; determining a first to sixth velocities from the seventh to twelfth values; determining a first set of coefficients from the first to sixth velocities and the seventh to twelfth values; determining a second set of coefficients from the first, second, fourth, and fifth velocities and the seventh, eighth, tenth, and eleventh values; for each of the first set of coefficients, determining a variance with the corresponding coefficient in the second set of coefficients; determining a first variance sum by summing the first and second sets of coefficients' variances; and saving the first variance sum, the first set of coefficients, the first and second functions.

Abstract: A multifunctional opener includes a main body having two opposite sides formed with two upright clamping portions and having an inside formed with an engaging recess located between the two clamping portions. Thus, the clamping groove and the engaging recess of the main body are used to open seal caps of different sizes, thereby enhancing the versatility of the opener. In addition, the clamping groove or the engaging recess of the main body is engaged with the periphery of the seal cap so that the seal cap is closely clamped by the main body, thereby facilitating a user opening the seal cap.
