Title: The Innovative Contributions of Stephen E. Little
Introduction
Stephen E. Little is a notable inventor based in Cupertino, CA, who has made significant contributions to the field of technology through his innovative patents. With a total of 2 patents, he has developed devices that enhance functionality and efficiency in various applications.
Latest Patents
One of his latest inventions is the hands-free gripping device for containers. This device is designed to hold generally cylindrical containers securely, preventing them from turning while being opened or closed. It features internal deformable ribbing that secures the container by canting slightly when turned, thereby wedging it in place. This mechanism resists rotation in either direction, making it practical for both opening and closing tasks. The device can be mounted on any flat surface, acting as a 'third hand' to allow users to operate with both hands or to use a single hand to grasp securely the closure being removed or secured from the container. This invention facilitates the assembly or disassembly of labware devices that require the application of torque.
Another significant patent is the optimum fixed angle centrifuge rotor. This invention provides a method for gradient density separation, supporting a generally cylindrical volume of sample solution with its axis inclined to the spin axis at an optimized angle. This design maximizes separation efficiency while minimizing contamination by undesirable centrifugates upon reorientation of the desirable centrifugates. The optimum angle is determined based on the relationship .theta.=Tan.sup.-1 (D/15L).sup.0.5, where D and L represent the diameter and length of the cylindrical volume of the sample solution, respectively.
