Abstract: An antenna for the transmission and reception of electromagnetic radiation is provided. The antenna includes a body portion, which can be flexible to permit incorporation of the antenna into a material. The antenna also includes an aggregate of extended length nanotubes along the body portion, and a plurality of contact points between adjacent nanotubes to permit transmission of electromagnetic radiation, while reducing resistivity along the antenna at a high frequency, for example, above 100 MHz. A method of manufacturing an antenna is also provided.

Abstract: A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system is coupled to a chamber that generates nanomaterials, typically carbon nanotubes produced from chemical vapor deposition, and includes a mechanism for spinning the nanotubes into yarns or tows. Alternatively, the system includes a mechanism for forming non-woven sheets from the nanotubes. The system also includes components for collecting the formed nanofibrous materials. Methods for forming and collecting the nanofibrous materials are also provided.

Abstract: A heat-conducting medium for placement between a heat source and heat sink to facilitate transfer of heat from the source to the sink is provided. The heat-conducting medium can include a disk having relatively high thermal conductivity and heat spreading characteristics. The heat-conducting medium also includes a first recessed surface and an opposing second recessed surface. Extending from within each recessed surface is an array of heat conducting bristles to provide a plurality of contact points to the heat source and heat sink to aid in the transfer of heat. The recessed surfaces may be defined by a rim positioned circumferentially about the disk. The presence of the rim about each recessed surface acts to minimize the amount of pressure that may be exerted by the heat sink and the heat source against the bristles. A method for manufacturing the heat-conducting medium is also provided.

Abstract: A paste feeder for moving paste from a paste cartridge to a cavity in a patient's mouth is described. The paste feeder has a paste cartridge for holding a paste and a paste channel defining a cavity for holding the paste cartridge. The paste feeder also has a paste feeder tube, operatively connected between the paste channel and a dispensing tip. A ratcheting device of the paste feeder operatively connects to a plunger. The plunger moves the paste from the paste cartridge through the paste feeder tube to the dispensing tip in controlled incremental amounts.
