Abstract: Clothing apparatus may include a jacket and gloves. The clothing apparatus includes illuminating elements, a power source, a controller, and hand operated switches. The gloves are in signaling communication with the controller, such as may permit the operator to cause signaling functions to occur by use of the hands without releasing, for example, the handle bars of a bicycle., and without having to fumble with external manual switches. The power and control units may be removable and rechargeable. The jacket may be water-resistant or water-proof, and may include a hood. The apparatus may include a photo-sensitive element and running lights such as may operate automatically as dusk falls.

Abstract: A system and method for controlling access to an object, logically grouped shared objects or an object associated with one or more logical groups in a multi-user environment having different user privileges is disclosed. In one embodiment, a method for locking based on user and user privileges includes receiving a request from a user for access to one of an object or logically grouped shared objects or an object associated with one or more logical groups, determining whether the request from the user is for the object, if so, determining whether the object is locked by another user, if so, breaking the lock associated with the user holding the lock on the object and allowing access to acquire a write lock associated with the user and granting access to the object, and ending the request session.
