A system in accordance with a present invention includes a host device and a fuel cell apparatus with an information storage device. A method of operating a host device in accordance with a present invention includes the step(s) of writing data to, and/or accessing data on, a fuel cell apparatus information storage device.

Systems including replaceable fuel cell apparatus and methods of using replaceable fuel cell apparatus

A fuel cell apparatus in accordance with a present invention includes an information storage device. A method of operating a host device in accordance with a present invention includes the step(s) of writing data to, and/or accessing data on, a fuel cell apparatus information storage device. A system in accordance with a present invention includes a host device and a fuel cell apparatus with an information storage device.

Replaceable fuel cell apparatus having information storage device

Alternative methods for refurbishing a single-use ink delivery container for a printing system are described. The refurbishing methods include electrical and mechanical reconfiguration or replacement of original elements on the ink delivery container. Each method utilizes an existing ink fluid outlet, electrical connector and an information storage device on the ink delivery container.

Ink container refurbishment system

A large variety of ink delivery systems for an existing ink-jet printing system are provided. The ink delivery systems include ink reservoirs of varying configuration and size which are capable of accommodating a variety of ink use rates. Each ink delivery system also has an electrical connector and an information storage device which are suitable for the various ink use rates. The information storage device may be a memory device circuit that provides enabling information to the printing system.

Ink delivery system adapter

The present invention concerns a fuel supply for a fuel cell. The fuel supply includes a fuel storage area configured to hold a fuel solution, a fuel solution outlet configured to pass the fuel solution from the fuel storage area, a waste storage area, a waste inlet configured to pass waste into the waste storage area, and a movable barrier separating the fuel storage area and the waste storage area. The movable barrier is configured to move as fuel solution is passed from the fuel storage area and waste solution is passed into the waste storage area to simultaneously decrease the volume of the fuel storage area and increase the volume of the waste storage area.

Fuel supply for a fuel cell

A method for storing data in an electrical storage device associated with a printing component of an ink-jet printing system. The electrical storage device is responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system. The electrical storage device includes a write once portion, a non-protected portion, and a protected portion. The write once portion or the protected portion contain information indicative of a refill ink in the printing component. Installation of the printing component into the printing system enables the printing system to alter information in the write once portion or the protected portion to indicate that the refill ink in the printing component has been used.

Electrical storage device for a replaceable printing component

The present disclosure relates to a replaceable printing component for use in a printing system having at least one replaceable printing component. The replaceable printing component is of the type sold through a plurality of sales channels. The replaceable printing component includes a radio frequency link for receiving information indicative of a particular sales channel of a plurality of sales channels. Also included in the replaceable printing component is an electrical storage device for storing information indicative of the particular sales channel. The electrical storage device provides information indicative of the particular sales channel for reordering the replaceable printing component.

Method and apparatus for identifying a sales channel

The present invention is a replaceable ink container for use in an off-axis printing system. The printing system is responsive to electrical signals from the replaceable ink container for controlling printer parameters. The ink container has a leading edge and a trailing edge relative to the direction of insertion into the printing system. The replaceable ink container includes a plurality of electrical contacts disposed on the leading edge toward a first side. The plurality of electrical contacts are configured for engaging corresponding electrical printer contacts associated with the printing system. Also included is a fluid outlet disposed on the leading edge toward a second side opposite the first side and spaced from the plurality of electrical contacts. The fluid outlet is in fluid communication with the replaceable ink container. The fluid outlet is configured for engaging a fluid inlet associated with the printing system.

Electrical and fluidic interface for an ink supply

The present disclosure relates to an ink jet printing system configured for receiving replaceable printing component. The ink jet printing system includes a replaceable printing component having an electrical storage device associated therewith. The electrical storage device has a data field therein specifying data organization within the electrical storage device. Also included is a printer portion configured to receive the replaceable printing component. The printer portion is adapted to read the data field within the electrical storage device and selectively access data within the electrical storage device based on the specified data organization.

Method and apparatus for checking compatibility of a replaceable printing component

The present invention deals with a replaceable printing component for an ink-jet printing system. The ink-jet printing system is of the type having at least one replaceable component. The replaceable component includes an electrical storage device that is responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system. The replaceable printing component includes a non-protected and a protected electrical storage portion. The non-protected electrical storage portion is responsive to write control signals for storing information provided to the non-protected electrical storage portion. The protected electrical storage portion has a protected state in response to an occurrence of a write protect active signal. In the protected state the protected electrical storage device prevents storage of information in the protected electrical storage portion. Both the protected and non-protected electrical storage portions are responsive to read control signals for transferring information stored in the protected and non-protected electrical storage portions, respectively, to the ink-jet printing system.
