Abstract: An inkjet printer includes: an ink container having an outlet port and a return port; a printhead having a first ink port and a second ink port; a first ink line interconnecting the outlet port and the first ink port; a second ink line interconnecting the return port and the second ink port; a bypass line interconnecting the first and second ink lines; a valve system for controlling fluid flow through the first ink line and the bypass line; and a controller for controlling the valve system. During printing, the controller is configured to open the first ink line and the bypass line.

Abstract: A fluid distribution system for a printhead. The system having a first fluid container a fluid connector for connection to a fluid input of the printhead; and a second fluid container connected between the first container and the connector for delivering fluid from the first container to the connector, wherein the second container is located relative to the first container and the connector so that a fluid pressure difference between fluid contained within the second container and fluid at the connector is independent of the amount of fluid contained within the first container.

Abstract: A laptop computer support system for elevating a laptop to a comfortable viewing level and adequate space for an external keyboard. The laptop computer support system includes a support frame, at least one support platform attached to the support frame, and a first support leg and a second support leg pivotally attached to opposing sides of the support frame. A first cable and a second cable are attachable to the first support leg and the second support leg respectively to prevent the legs from extending outwardly too far. Front and rear riser members are preferably attached to the legs for allowing height and angle adjustment.

Abstract: A multi-purpose display module system for an electrical instrument has a readily detachable display module for remote use that can be quickly reattached. The display module is readily adjusted in tilt angle, whether attached or remoted. A front frame with a recess is mounted on the front of a main chassis for the instrument. Latches are mounted on the main chassis and extend into the recess on opposite sides of the recess, the ends of the latches defining a rotation axis across the recess. A display module has clutch assemblies frictionally, rotatably mounted on opposing sides to fixedly engage the ends of the latches when the display module is mounted within the recess. Release of one latch allows the display module to be removed and set up independently with a stand integral with the clutch assemblies, the display module being electrically connected to the electrical instrument by an electrical cable of suitable length.

Abstract: A carrier tray for circuit board assemblies. A metal plate is provided (by spot molding) with non-conductive plastic rails. Fastening means are molded into the rails to accommodate variations of circuit board assemblies. Locating posts in combination with resilient locking fingers and circuit board edge receiving slots are formed in the rails to provide a fastening system that is independent of separate fasteners and tools therefor. Lifting levers, also molded into the upper rail, provide for easy removal of the carrier tray from its interconnected position in a card cage.

Abstract: Packaging for an electrical instrument wherein the electrical field is to be contained in a metal card cage and the card cage enveloped in a plastic shell. Fastening towers or stems are molded in the base portion of the plastic shell and key slotted windows in the card cage drop over the tower and slid under a ledge of the tower to secure the card cage to the base. Main interface circuit boards having keyslots are adapted to interfit the protruded end of the fastening towers. Biased locking lugs enter the slots in the "seated" or "home" positions of both the card cage and circuit board to interlock the three components all without separate fasteners and with a minimum of time and effort.
