Abstract: Systems and methods are provided for delivering a work part to an assembly line worker using a dolly assembly in a first configuration and retrieving the work part from the dolly assembly by the assembly line work while the dolly assembly is in a second configuration. According to some embodiments, a dolly assembly is provided comprising a base assembly having a support member and a mobility mechanism, the support member positioned obliquely with respect to a horizontal plane. The dolly assembly also includes a part-carrying member rotationally connected to the support member and having a part-holding structure for receiving a work part. The part-carrying member extends downward at an angle below the horizontal plane when in a first configuration, and extends upward from at an angle above the horizontal plane when in a second configuration.

Abstract: The present invention provides a method of providing a temporary telephone number for a telephone having a directory number. Upon receiving a call request including a called number, the communication system determines if the called number is a temporary telephone number. If the called number is a temporary telephone number, the communication system determines the directory number of a phone associated with the called number. The communication system then routes the call to the phone, preferably by using the directory number of the called phone. When finished using the temporary telephone number, the communication system returns the temporary phone number to a pool to be used again by a different user as a temporary telephone number.
