  • Step-wise fabrication of conductive carbon nanotube bridges via dielectrophoresis
    Patent number: 11912900
    Abstract: Carbon nanotube (CNT) agglomerates can be aligned along the field lines between adjacent electrodes to form conductive bridges. The present invention is directed to a stepwise process of dielectrophoretic deposition of CNTs to form conducting bridges between adjacent electrodes spanning lengths over 50 microns. The CNT bridges are permanently secured using electrodeposition of the conducting polymer polypyrrole. Morphologies of the CNT bridges formed within a frequency range of 1 kHz and 10 MHz are employed and explained as a consequence of interplay between dielectrophoretic and electroosmotic forces. Postdeposition heat treatment increases conductivity of CNT bridges likely due to solvent evaporation and resulting surface tension inducing better contact between CNTs.

  • Headrest mount for tablet computer and method
    Patent number: 9010597
    Abstract: A device and method is presented that attaches a tablet computer to a vehicle headrest. A two-piece mount has a headrest coupling and a tablet housing. The tablet housing has a rigid core attached to a flexible rim portion that secures the tablet computer within the tablet housing. The rigid core has a circular cavity in the rear. The headrest coupling mounts to headrest posts in a vehicle using hinged arms and locking clips. The headrest coupling further has a circular attachment disk that fits within the circular cavity of the tablet housing. Retractable tabs in the circumference of the attachment disk fit within tracks in the walls of the circular cavity. The tabs prevent accidental separation of the tablet housing from the headrest coupling, and allow rotation of the tablet housing when attached to the headrest coupling.
