The present disclosure relates to articles (and the manufacture thereof) that use electrical energy to heat a material to form an inhalable substance, the articles being sufficiently compact to be considered “hand-held” devices. In certain embodiments, the articles can particularly be characterized as smoking articles. The smoking article can be adapted to detect the status of a cartridge portion of the smoking article. The smoking article includes a control body portion having a control body engagement end, wherein the control body portion houses a control component and a power source therein. The article further includes a cartridge body portion that has a cartridge body engagement end configured to removably engage the control body engagement end of the control body portion. The cartridge body portion houses a consumable arrangement and a heating connection operably engaged therewith comprising at least one heating element and a fusible link.

A method is provided for the fabrication of fuses within a semiconductor IC structure, which fuses are delectable by a laser pulse or a low voltage electrical pulse typically below 3.5 V to reroute the electrical circuitry of the structure to remove a faulty element. The fuses are formed on the surface of circuitry which is coplanar with a surrounding dielectric such as the circuitry formed by a Damascene method. A preferred fuse material is silicon-chrome-oxygen and the preferred circuitry is copper.

A fuse array having a plurality of fusible links that can be addressed by two electrodes is disclosed. The fuse array includes two conductive strips having the plurality of fusible links located therebetween and electrically coupled to the conductive strips. The fusible links have different electrical resistance and each fusible link includes a fuse portion. A voltage potential applied across the conductive strips induces current flow through the fusible links in accordance with Ohm's law and ohmic heating occurs at the fuse portion in proportion to the square of the current. The voltage is increased to cause sufficient ohmic heating to occur in the most conductive fusible link (the fusible link having the lowest electrical resistance) so that the fuse portion in that fusible link fuses. Because the fusible links are connected in parallel to the conductive strips, an equivalent resistance of the plurality of fusible links increases and the current flow diminishes so that no further fuse portions are fused at the selected voltage level. Thereafter, the voltage level may be increased to fuse the most conductive fusible link remaining that is not fused. The fuse array may be incorporated into a circuit as a resistor that can be tuned to circuit requirements or as a physical structure in MEMS devices wherein the fuse array may be tuned to change physical properties of the MEMS device.

A method and apparatus according to various aspects of the present invention is configured to automatically reset a rollable fire door curtain in the raised position. In one embodiment, a brake is coupled to a rolling fire door axle by an electromechanical clutch. The fire door is pre-disposed to unroll and close the opening, however, the brake prevents the door from unrolling. When a switch, a signal, or a fusible link indicates that the fire door should close, an electromechanical circuit board sends an electrical signal to an electromechanical clutch which opens the clutch. With the clutch open, the brake is no longer coupled to the fire door and the door closes. When the switch or signal is reversed, the clutch closes, re-coupling the fire door axle to the brake. The brake allows input rotation in both directions, but prevents the rolling door from closing under its own weight. Therefore, upon raising the curtain, the fire door is automatically reset and ready to close in the event of a fire.

Provided are interconnect circuits for interconnecting arrays of battery cells and methods of forming these interconnect circuits as well as connecting these circuits to the battery cells. An interconnect circuit may include a conductive layer and one or more insulating layers. The conductive layer may be patterned with openings defining contact pads, such that each pad is used for connecting to a different battery cell terminal. In some embodiments, each contact pad is attached to the rest of the conductive layer by a fusible link formed from the same conductive layer as the contact pad. The fusible link controls the current flow to and from this contact pad. The insulating layer is laminated to the conductive layer and provides support to the contacts pads. The insulating layer may also be patterned with openings, which allow forming electrical connections between the contact pads and cell terminals through the insulating layer.
