Abstract: Methods for constructing multi-walled carbon nanotube (MWCNT) antenna arrays, may include: variable doping of the MWCNTs, forming light pipes with layers of variable dielectric glass, forming geometric diodes on full-wave rectified devices that propagate both electrons and holes, using clear conductive ground plans to form windows that can control a building's internal temperature, and generating multiple lithographic patterns with a single mask.

Abstract: The present disclosure describes a system with a power management device, a wakeup circuit, a battery management device, and a connector. During a powered down mode of operation, the battery management device can provide, via the connector, a bias voltage to the wakeup circuit. In response to a wakeup switch being activated, the battery management device can provide a power supply (e.g., from a battery) to the power management device. Benefits of the wakeup circuit include (1) a reduction of battery consumption—and thus improving battery lifetime—when the electronic system is in a powered down mode of operation because the wakeup circuit has lower number of active components compared to other designs and (2) a non-complex wakeup circuit design because one or more existing connector interconnects between the power management device and the battery management device can be re-used during electronic system's powered down mode of operation.

Abstract: An ultracapacitor is manufactured from a woven carbon fiber material that is partially saturated with structural resin. The portion of the carbon fiber material that contains the resin may be used as a structural element in spacecraft or other applications. The carbon fibers of the woven material are used both as the current collector and the electrode. Activated carbon fiber material may be used or only the electrode portion of the carbon fibers may be activated.

Abstract: An improved battery paste composition and a lead-acid electrochemical cell which incorporates the composition. The cell includes a positive current collector and a negative current collector which are each coated with a paste containing one or more lead-containing compositions and a paste vehicle to form a positive plate and a negative plate. An absorbent electrolyte-containing separator member may also be positioned between the positive and negative plates. The paste on the positive current collector, the negative current collector, or both further includes a special additive consisting of polyvinylsulfonic acid or salts thereof which provides many benefits including improved battery cycle life, increased charge capacity, and enhanced overall stability. The additive also makes the pastes smoother and more adhesive, thereby improving the paste application process. The paste compositions of interest may be used in conventional flat-plate cells or in spirally wound batteries with equal effectiveness.

Abstract: A vending device for newspapers or other articles comprising a box like receptacle which can be pole or pedestal mounted. The device includes a one piece paper display member, an access door biasing means which is hidden from exposure to the weather, a door latch device which maintains the access door in an open position, a releasable lock device for locking a coin operating mechanism and coin box in the vending device and an access door locking unit for locking the access door to the coin operating mechanism.

Abstract: A device for retaining a book, such as a telephone directory, in a holder or on a flat surface, in order to prevent unauthorized removal or theft of the book. A plurality of pin-like retainer members are mounted in a pair of mounting members in laterally spaced, parallel relation. The number of retainers is determined by the thickness of the book. The pointed ends of the pin-like retainer members are shifted into the ends of the book and the assembly is secured either to the flat surface or to a support bar that is riveted or otherwise secured to the inner surface of the back of the holder. The pin-like retainers are frictionally retained either in a series of laterally spaced slots or bores in the mounting members so as not to be removable therefrom without the use of a tool and a substantial amount of force.

Abstract: A telephone enclosure assembly and directory holder device for use with indoor/outdoor telephone installations. The enclosure includes a one-piece cast or molded plastic housing shell. Side panels can be fastened to the shell and a security lock clip permits the panels to be locked in place but readily replaced in the event of sidewall damage or vandalism. A directory holder is attached to the shell and is capable of storing several directories which can be rotated from a closed position to an open position, allowing each reader to comfortably view all printed matter on each and every page of the directory.
