Patent number: 9500633Abstract: An improved fruit tester and method provides a plunger intrusion-type mechanism, a precision scale and an associated computer for control of the mechanism and for recordation, presentation and analysis of data sensed by the mechanism. An electrically powered variable speed motor carries an optical encoder to sense rotary direction and speed data, which is transmitted through circuitry to an associated computer for analysis to determine control data to maintain pre-programmed motor function. Computer software determines plunger position and resultant penetration into a fruit at either pre-determined plunger speed or constant plunger resistive pressure in fine increments over the plunger trajectory and stores this data in computer memory. The precision scale is used to determine the weight of the fruit before and after the penetration tests and the difference in weight is used to automatically calculate the Specific juice Content (SJC) of the fruit.Type: GrantFiled: November 18, 2014Date of Patent: November 22, 2016Inventors: Charles L. Mohr, Brandt Mohr, Anthony Cottam, Kevin D. Dawes, Preston May, Christopher M. Mulkey, Duan D. Nguyen, Marc D. Pirello, Michael D. Stordahl, James M. Van Corbach, Jr., Erik Von Reis
