A system for determining a number of concurrent connections at a start time of a connection record is provided. In addition, the non-contact glass shearing device and method can horizontally scribe or cut the downward moving glass sheet so that it can be separated into distinct glass sheets. A first multi-step valve lift mechanism may be supported on the engine structure and engaged with the first valve. The fraction of light transmitted into the second prism is reflected back and redirected out of the system toward the incoming beam. The sealing substance is either a greaseless elastomeric sealant coated on one or both of the pair of elements or a pure metal applied to each of the pair of elements. More particularly, the compounds of the invention are motilin receptor antagonists useful for the treatment of associated conditions and disorders such as gastrointestinal reflux disorders, eating disorders leading to obesity and irritable bowel syndrome.
