Abstract: A method and apparatus for multipurpose navigation in a portable electronic device are described. According to an exemplary embodiment, a portable electronic imaging device is described including a display screen for displaying objects including at least one of digital still images, video clips, menu items, and icons. The device also includes a navigation controller comprising navigation keys for allowing a user to navigate between the displayed objects by pressing a portion of the navigation controller corresponding to a navigation key last pressed to navigate between the displayed objects, wherein the device is configured to allow the user to select a currently displayed object without moving a finger from the portion of the navigation controller corresponding to the navigation key last pressed to navigate between the displayed objects, thereby implementing navigation and select functions on a single portion of the controller.

Abstract: A lid for a container holding a flowable substance has an annular top wall. A side wall depends from the top wall, and has a mounting portion for connecting the lid on the container. The top wall has an opening that is adapted to permit the flow of the substance through the lid. The top wall also has a retaining member. The lid further has a closure member positioned on the mounting portion. The closure member is movable between a first position and a second position, wherein at least a portion of the closure member is received in the opening in the first position and at least a portion of the closure member is received in the retaining member in the second position. The opening and the closure member are cooperatively dimensioned such that the closure member is removably inserted in the opening. The retaining member and the closure member are cooperatively dimensioned such that the closure member is removably inserted in the retaining member.

Abstract: The embodied systems are used to manage consumables used in an ink jet print system and to prevent use of unauthorized printheads or unauthorized ink supply containers in an ink jet printing system. The embodiments are used on typical ink jet printing systems that include a printhead, an ink supply container, a carriage board in communication with the printhead, and a main board in communication with the ink supply container and the carriage board. The novel systems include a serial device disposed on the printhead or the ink supply container having a unique signature which is then authenticated by firmware and hardware of the printing system.

Abstract: A control system having a host computer and one or more control computers connected to an interface for control of a process or machinery. The control computers are capable of automatically initiated network address assignment and configuration when powered up after installation. The network address is based on a location identifier situated in the interface that corresponds to a specific connection thereof to the control computer. The control computer reads the location identifier from the interface and requests a network address. The host computer assigns the network address based on the location identifier. Configuration of the control computer then proceeds. The procedure applies to newly installed control computers, whether first time installment or a replacement for a failed control computer.

Abstract: A surgical scalpel has a flat blade, which may have a cutting or severing edge, and an elongated ergonomic handle having distal and proximal ends and an imaginary central axis. In one preferred embodiment, of a disposable (one use) scalpel the blade is embedded in a molded plastic resin handle. The handle has a generally triangle shape in cross-section with the top face being slightly curved. The handle, near its distal end, has an enlarged finger pressure section having an indentation at its top face adapted for a finger pad to apply pressure to the scalpel handle.

Abstract: A reclosable lid 10 for a container holding a flowable substance has a first piece or cover 12, and a movable second piece or disk 50. The cover 10 has a top wall 14, a side wall 16 and a mounting portion 22 for connecting the lid 10 on the container. The cover 12 has an opening 28 adapted to permit the flow of the substance through the lid 10. The cover 12 further includes a slot 30 located in the top wall 14. The disk 50 has at least one aperture 78, a post 54, and a projection 52. The aperture 78 and the projection 52 are each cooperatively dimensioned with the opening 28. The post 54 is adapted to be received by the slot 30 in the cover 12. The disk 50 is movable between a first position wherein at least a portion of the projection 52 is received in the opening 28 in the first position, and a second position wherein the aperture 78 is aligned with the opening 28 in the second position.
