Disclosed are methods and systems for measuring and managing swelling of rechargeable batteries in situ. Some implementations involve using capacity fade or state of health of rechargeable batteries to estimate swelling of the rechargeable batteries. Some implementations provide methods and systems for measuring battery swelling based on inductive or capacitive coupling between sensors and the battery. Some implementations provide means to manage or reduce swelling of rechargeable batteries by applying adaptive charging with consideration of battery swelling.

A catalyst material for carbon nanotube synthesis includes a uniform dispersion of host particles on a substrate. The host particles themselves include catalyst nanoparticles that are effective to catalyze nanotube syntheses reactions and provide nucleation sites. Methods for preparing catalyst materials include co-sputtering a catalytic species and a host species to form a precursor thin film on a substrate, followed by an oxidation reaction of the precursor thin film in air. The precursor thin film can be patterned on the substrate to limit the locations of the catalyst material to well-defined areas. Methods for nanotube synthesis employ CVD in conjunction with the catalyst materials of the invention. During the synthesis, the catalyst nanoparticles catalyze carbon nanotubes to grown from a carbon-containing gas.

Methods for performing cathode burn-in with respect to an FED display that avoid display non-uniformities near and around the spacer wall structures. In a first method, the anode is floated or receives a negative voltage with respect to the electron emitter. A positive voltage is then applied to the focus waffle structure with respect to the electron emitter. The cathode is then energized thereby preventing emitted electrons from escaping the focus well. Under these conditions, cathode burn-in conditioning can occur but electrons are energetically forbidden from hitting the anode or the spacer walls except for a small region near the focus waffle. Under the second method, the anode is grounded or allowed to float. A negative bias is applied to the focus waffle. This causes electrons to be collected at the M layer of the gate. Electrons are energetically forbidden from hitting any portion of the tube except the M layer. Under either method, no electrons hit the spacer walls and therefore display non-uniformities near and around the spacer wall structures are avoided.

The intensity at which electrons emitted by a first plate structure ( ) in a flat-panel display strike a second plate structure ( ) for causing it to emit light is controlled so as to reduce image degradation that could otherwise arise from undesired electron-trajectory changes caused by effects such as the presence of a spacer system ( ) between the plate structures. An electron-emissive region ( ) in the first plate structure typically contains multiple laterally separated electron-emissive portions ( and ) for selectively emitting electrons. An electron-focusing system in the first plate structure has corresponding focus openings ( P and P ) through which electrons emitted by the electron-emissive portions respectively pass. Upon being struck by the so-emitted electrons, a light-emissive region ( ) in the second plate structure emits light to produce at least part of a dot of the display's image.

A structure that is suitable for partial or full use in a spacer of a flat-panel display. The structure may be formed with a porous body having a face along which multiple primary pores extend into the porous body. A coating consisting primarily of carbon and having a highly uniform thickness overlies the porous body's face, extending along the primary pores to coat their surfaces and converting the primary pores into further pores. The coating can be created by removing non-carbon material from carbon-containing species provided along the pores. A solid porous film whose thickness is normally no more than 20 &mgr;m has a resistivity of 10  ohm-cm. A spacer for a flat-panel display contains a support body and an overlying, normally porous, layer whose resistivity is greater parallel to a face of the support body than perpendicular to the body's face.

A flat panel display that has internal components that are cleaned using a dry cleaning treatment. The cleaned internal components include a matrix structure, a focus structure and a support structure. The dry cleaning treatment removes contaminants from the surfaces of the internal components. By cleaning the internal components, contaminants are removed that can deleteriously affect the performance of the display. The cleaned support structure has uniform resistance and does not produce spatially nonuniform resistivity over time. This prevents regions of the visible display that are not properly illuminated and minimizes the possibility of arcing.
