An anti-theft lock assembly used in conjunction with ignition switches and locks which are operated by universal keys. When processing a read or a write command, a scheduling arbiter examines a bus schedule to determine that a read-read conflict, a read-write conflict or a write-read exists, and allocates an available memory space in a read buffer to store the read data causing the conflict until the read return data transmission can be scheduled. This enables a single code word to be used to address either a single paging group or multiple paging groups. If the requested operation is a direct formatting operation, the request may be denied. The medical device may be used to approximate the septal and lateral annulus of the mitral valve in order to move the posterior leaflet anteriorly and the anterior leaflet posteriorly and thereby improve leaflet coaptation and eliminate mitral regurgitation. A facet of the semiconductor optical waveguide-A facing an isolation trench and a facet of the semiconductor optical waveguide-B facing the isolation trench are configured as a composite optical reflectoroptical connector using an optical interference.
