A force sensor particularly suited for use in an electronic stylus that senses the contact force on its nib for recording pen strokes and handwriting recognition. The sensor has a housing for a load bearing member for receiving an input force to be sensed and associated circuitry for converting the input force into an output signal indicative of the input force. The bearing member is movably mounted within the elongate body (up to 100 microns). The input force acting on the load bearing member is caused by contact on the nib. The load bearing member is biased against the direction of the input force.The force sensor also has a light source and photo-detector for sensing levels of illumination from the light source. Associated circuitry converts a range of illumination levels sensed by the photo-detector into a range of output signals, so that the illumination level sensed by the photo-detector varies with movement of the load bearing member within the elongate body such that the output signal from the circuitry is indicative of the input force. Using an optical sensor avoids the need to use a delicate piezo-resistive sensor that requires careful tolerancing during production.

This relates to an intelligent ink cartridge and method for manufacturing the same. The ink cartridge comprises at least one ink chamber for containing ink, an electronics module for storing identification information of the ink cartridge and ink remaining data. The electronics module comprises a micro-controller with embedded non-volatile memory, for storage, controlling, calculation and accessing of ink remaining data, so that the maximum ink capacity of the ink cartridge for use with the printer can be improved.

The invention relates generally to the field of inkjet recording media and inkjet printing methods. More specifically, the invention relates to a porous base layer of an inkjet recording element, the base layer comprising precipitated calcium carbonate having scalenohedral morphology.

A casing (9, 10) for a cartridge (5) which is adapted for supplying print media (12) and an ink to an inkjet printhead with which the cartridge (5) is engaged, the casing (9, 10) including: a core (6) rotatably mounted inside the casing (9, 10) which is adapted to support a roll of print media (12); an ink supply inside the core (6); and at least one ink outlet at one end of the core (6) for establishing fluid communication between the ink supply and the printhead.

The present invention provides an ink cartridge recovery method and a recovery ink cartridge. The ink cartridge comprises: a casing and an ink storage chamber located in the casing. The ink storage chamber includes a first sub-chamber and a second sub-chamber. The first negative pressure control mechanism, the housing is provided with an ink outlet at a position corresponding to the first sub-chamber, the ink outlet communicates with the first sub-chamber, and the ink cartridge recovery method includes: connecting the housing with the first sub-chamber An opening is opened at a corresponding position; the first negative pressure control mechanism is moved into the second sub-chamber; the second negative pressure control mechanism is arranged in the first sub-chamber through the opening; and the opening is sealed and packaged. The first negative pressure control mechanism and the second negative pressure control mechanism are used together to store ink and increase the capacity of the ink cartridge. At the same time, the new second negative pressure control mechanism in the first sub-chamber corresponding to the ink outlet has a stronger Adsorption force and control force ensure that the ink can still be kept in the ink storage chamber after expanding the ink capacity, avoiding ink leakage and improving the performance of the ink cartridge.
