Patent CA-2315132-A1 (CA)
Title: Method for fabrication of patterned carbon nanotube films
Inventor: BOWER CHRISTOPHER A
IPC: B82B3/00
Filed: 2000-08-04
Abstract: A method for fabricating adherent, patterned carbon nanotube films is provided. According to the invention, a substrate is patterned with a carbide-forming material, a carbon-dissolving material, or a low melting point metal. Carbon nanotubes are then deposited onto the patterned substrate, but have relatively poor adhesion to either the substrate material or the patterned material. The substrate is then annealed, typically in vacuum, at a temperature dependent on the particular patterning material, e.g., a temperature at which carbide formation occurs, at which carbon dissolution occurs, or at which the low melting point metal melts. The annealing thereby provides an adherent nanotube film over the patterned areas, while the nanotubes deposited onto the non-patterned areas are easily removed, e.g., by blowing, rubbing, brushing and/or ultrasonication in a solvent such as methanol.
Patent CA-2315387-A1 (CA)
Title: Athletic glove having silicone-printed surface for consistent gripping ability in various moisture conditions
Inventor: KANG HYE-SOOK
IPC: A63B71/14
Filed: 1998-12-10
Abstract: An athletic glove having consistent gripping ability in various moisture conditions includes a palm portion and a back portion joined together to fit the human hand. The palm portion is made of a thin synthetic leather material printed with a pattern made of silicone sealant printed on the synthetic leather to form a contact surface covering a minority of the exterior contact area portion for gripping, by penetrating the printed pattern of silicone sealant into the synthetic leather to form a plurality of anchored channels, the contact surface occupying substantially the same plane as the exterior contact area portion, to allow for a capillary action between the contact surface and the synthetic leather. The pattern is preferably achieved by silk-printing on contact areas of the palm portion with a two-part silicone sealant in a repeated pattern of fine lines of a narrow width, to penetrate and bond firmly with the fiber thereof after curing and thereby improve gripping ability over that of bare artificial leather and impart consistent gripping ability in various moisture conditions without losing the original good, soft and supple feel, finger motion, and tactile response of the original material. A  majority of the palm portion surface does not bear the silicone printing and thus prevents the thin film effects of water, because moisture on the silicone surface is promptly absorbed by capillary action into the leather material adjacent to the contact surface of the printed silicone sealant.
Patent CA-2315962-A1 (CA)
Title: System and method for wireless local calling
Inventor: MYER ROBERT EVAN
IPC: H04W72/02
Filed: 2000-08-08
Abstract: A wireless communications technique enables direct call set up and communication between wireless subscribers without involving network infrastructure. A mobile is modified to perform like a network base station during a local calling mode initiated by a user, thereby reversing transmit and receive frequency bands and allowing the mobile to set up and carry out a call as if it were a network base station. The mobile initially performs a communication channel or frequency sweep sequence to determine an idle traffic channel, thereby preventing interference with other subscribers.  After a local call is established, the transceiver monitors call quality, and performs another communication channel or frequency sweep sequence to select a new traffic channel when call quality drops below a threshold level to ensure a certain level of call quality between the first and second mobiles.

Title: Method and apparatus for controlling drilling of rock drill
Inventor: MUUTTONEN TIMO
IPC: E21B1/00
Filed: 1999-03-16
Abstract: The invention relates to a method for controlling drilling of a rock drill, in which method a pressure sensor (20) measures the pressure in a space situated behind pistons (4a, 4b, 14a, 14b) supporting a shank (2).  The pressure value measured is used to monitor a return pulse that is reflected from the rock to the drill bit and further via the drilling apparatus to the pistons (4a, 4b, 14a, 14b), the return pulse making the pistons move backward and thus causing an increase in the pressure in the space behind the pistons (4a, 4b, 14a, 14b). This, in turn, results in a pressure pulse (B) which can be detected by the pressure sensor (20) and which differs from normal pressure variation (A) caused by the impact motion. On the basis of this pressure pulse (B), a control unit (21) adjusts the feed and the impact power of the drilling machine as well as other parameters affecting the drilling. The invention further relates to an apparatus comprising means for implementing the measurement of pressure pulses (B) according to the method.

Abstract: A second network such as an interexchange carrier advantageously identifies incorrect original number portability data from the first network such as a local telephone company and obtains new number portability data to prevent misrouted calls.  The second network receives original number portability data from the first network. The second network determines whether to use the original number portability data from the first network for call routing. If the original number portability data from the first network is not used for call routing, the second network generates and transmits a query to obtain new number portability data for call routing. The second network receives the new number portability data for call routing in response to the query. The second network then generates and transmits a route instruction using the new number portability data. If the original number portability data from the first network is used for call routing, the second network generates and transmits the route instruction using the original number portability data. In some embodiments, the threshold for misrouted calls ensures that incorrect number portability data is not used repeatedly and the correct number portability data is used for call routing.
