  • Publication number: 20220125223
    Abstract: A picture frame hanger includes a horizontal level bar. The horizontal level bar has a top leveled surface with a bottom curved edge. A securing tab extends upwards from the top leveled surface and provides an attachment point for a picture frame with standard hanging hardware. The top leveled surface provides a level surface for the standard hanging hardware to rest and the bottom curved edge allows for the rotation of the picture frame hanger and the attached picture frame to level the attached picture frame. A vertical support bar extends downward from the horizontal lever bar and provides a lever arm to counteract the downward force created by the weight of the picture frame to prevent the picture frame hanger and picture frame from tilting forward.

  • Patent number: 6009323
    Abstract: A method is provided for placing a call from a two-way radio subscriber unit operating within a two-way radio communication system (100). A user operates the subscriber unit in a call address search mode (310), and provides search criteria data that references a communication target (320). The search criteria data is transmitted in a query to system equipment which provides, in response, a list of matching identifiers and corresponding call addresses (330, 340). This list is presented to the user and a selection obtained (350, 360). A call address corresponding to the user selection is used to initiate the call to the communication target (370).
