摘要： A fluid supply is provided, which includes a body defining a storage space configured to contain a fluid, a first electrode and a second electrode contained within the storage space and configured to be in direct contact with the fluid, wherein the first electrode and second electrode are configured to be connected to external power supply circuitry for applying an alternating signal across the first and second electrodes, and a first electrical contact in electrical communication with the first electrode and a second electrical contact in electrical communication with the second electrode. The first electrical contact and second electrical contact are to be connected to the external power supply circuitry and to detector circuitry for determining a measured impedance value of the fluid.

摘要： The present disclosure relates to an inkjet printing system for depositing ink on media. The inkjet printing system includes an ink containment vessel formed from a material having optical characteristics selected to block light in the visible light spectrum. Also included is an energy source for providing energy having characteristics that are selected to allow energy passage through the ink containment vessel. Finally, an energy detector is included for detecting energy provided by the energy source that passes through the ink containment vessel. Energy from the energy source impinging upon ink is altered so that an energy detector output signal is indicative of ink within of the ink containment vessel.

摘要： A device for determining drop volume for a drop ejection device is disclosed. The drop ejection device has a drop ejector and a reference drop ejector that exhibits less drop volume variation than the drop ejector. The drop ejection device includes a sensor responsive to impinging drops for producing a signal proportional to drop volume. The sensor is responsive to drops from the drop ejector to produce an electrical signal. The sensor is responsive to drops from the reference drop ejector to produce a reference electrical signal. Also included is a processing device responsive to the electrical signal and reference electrical signal for determining drop volume of the drop ejector relative to drop volume of the reference drop ejector.

摘要： The present invention is a fluid level sensing system which has a single light source for providing light rays and a single light receiving device for receiving the light rays. The fluid level sensing system also has a fluid container which has a plurality of controlled surfaces arranged on the fluid container. Each controlled surface exhibits a first reflected light characteristic if fluid within the fluid container is in contact with the controlled surface and a second reflected light characteristic if the fluid is not in contact with the controlled surface. The controlled surfaces are disposed on the fluid container so that the light rays from the single light source impinge upon each of the controlled surfaces to produce either the first or the second reflected light characteristics and are thereby detected by the light receiving device to determine the fluid level in the fluid container.
