Abstract: The invention relates to polymorphous forms of (+)-(S)-clopidogrel hydrogen bromide, described as polymorphous “form A”, polymorphous “form B”, polymorphous “form C”, polymorphous “form D”, polymorphous “form E”, and polymorphous “form F”, in addition to polymorphous forms of (+)-(S)-clopidogrel napsylate, that are described as polymorphous “form A” and polymorphous “form B” and differ in the X-ray powder diffraction diagrams (XRPD) thereof. The invention also relates to the salts clopidogrel besylate, clopidogrel tosylate and clopidogrel oxalate, and to methods for the production thereof.

Abstract: A system and method for remotely managing a security area such as a safe deposit box repository providing ready access by a community of users includes one or more identity-confirmation steps, followed by granting permission to enter a first secure area. Within the first secure area, further identity-confirmation steps are performed before access to a second secure area is remotely authorized. Inside the second secure area, the user unlocks one mechanism which secures his specific safe deposit box and, if implemented in the particular vault, a second portion is remotely unlocked, permitting the user access to his box. Egress involves replacing the user's safe deposit box into the assigned location, then exiting to the first secure area. After the door between the second and first secure areas closes, exit from the first secure area is permitted. Identity-confirmation steps may include cards, PINs, biometric tests, visual identification, or other suitable steps.
