Abstract: A Lasagna noodle cooking and drying rack including, a plurality of noodle cooking shelves formed from a plurality of horizontal shelf arms and a plurality of horizontal support members with the horizontal shelf arms attached to a plurality of vertical shelf support structures at an incline to hold the noodles securely on their individual shelves during the cooking process. Cooking the noodles on their individual shelves prevents the noodles from sticking together and promotes even cooking of the noodles which in turn prevents them from breaking apart when they are removed from the cooking water. The Lasagna noodle cooking and drying rack has a removable handle which can be hooked on to the two end vertical support structures to lift the rack from the cooking pot. The Lasagna noodles can be drained and dried on their individual shelves after the rack is lifted out of the cooking water.

Abstract: A safety controller with redundant controllers, each executing safety tasks and comparing their results, provides an improved interface in which a user interacts with a single processor and the second processor is invisible. The interacting processor provides for the transmission of programs and variables to both processors when they are safety tasks and coordinates synchronization of the two programs and comparison of their operation all without additional user input.

Abstract: A safety controller executes a control program in two processing units to detect processor failure by comparison of the execution in each unit. This comparison is made rapid by synchronizing the input variables at the beginning of the task and comparing output variables at a conclusion of the task, avoiding line-by-line comparison of input and output variables. Intermediate variables, that are neither input nor output values, are compared at a less frequent interval.

Abstract: A safety controller provides for reliable mixed execution of standard and safety control programs held in a common memory by providing a hardware lock that is locked at times when the safety program is not executing to minimize potential corruption of the safety program by the standard program.

Abstract: Re-certification of a control program loaded in a safety controller is avoided through the use of a digital snapshot and digital signature, the snapshot providing a rapidly loadable memory image file and the signature providing a confirmation that the file loaded matches a previously certified copy so as to avoid the need for time consuming re-certification.

Abstract: A golf swing analyzing device and method in which a first ball is suspended for rotation about a substantially horizontal axis and a second ball is suspended at some distance from the first ball for rotation about a substantially horizontal axis to provide two spaced targets for analyzing the golf swing at two locations in the swing hitting zone.
