Abstract: A fluid pump apparatus includes a pump chamber in a wellbore, a drive line capable of transferring a gas pressure to the pump chamber, a control system, an exhaust line, and a pressure sensor. The pressure sensor is capable of remotely sensing gas pressure in the exhaust line and providing communication to the control system. The control system is capable of determining when the fluid level in the pump chamber is full or near full based on input from the pressure sensor.

Abstract: A heater chip has a substrate and at least one die, made of silicon, and a bond non-adhesively attaching them. The substrate, thick enough to resist bowing, has ink supply vias from back to front surfaces. The die has ink flow vias from back to front surfaces and circuitry including heater elements adjacent the front surface interspersed with ink flow vias. A metal through the die connects a conductor on a front of the substrate to a heater element on a front of the die. A wire bond connects to the front of the substrate, but is offset from die.

Abstract: Electroluminescent (EL) displays, media, and members, and methods associated therewith. One such display includes an EL material, conductor layers, and a reflective image formed by a pattern of imaging substance applied adjacent at least one of the conductor layers. The EL material is between at least two of the conductor layers, and at least one of the conductor layers is applied adjacent the EL material in a pattern to form a conductive image. Upon application of an operational potential to the at least two of the conductor layers having the EL material therebetween, the display can be illuminated in an area corresponding to the conductive image.

Abstract: A method informs a user of an ink jet printer of the end of life of a consumable. The consumable supplies ink to a printhead having a plurality of ink ejection nozzles and an associated plurality of ink jetting actuators, each of the plurality of ink jetting actuators being addressable. The printhead includes a plurality of address lines for facilitating selection of one or more of the plurality of ink jetting actuators. The method includes the steps of defining a notice threshold that is associated with a corresponding amount of ink remaining in the consumable; providing control logic for selectively controlling the plurality of address lines; determining whether the amount of ink remaining in the consumable has reached the notice threshold; and upon reaching the notice threshold, reducing an image density of images formed by the printhead by selectively disabling at least one of the plurality of address lines.
