Method And Apparatus For Targeting Advertising In Overlapping Sales Territories

US Patent:
2001004, Nov 15, 2001
Filed:
Mar 31, 1999
Appl. No.:
09/282751
Inventors:
LEO CHAN - BELMONT CA, US
KING-SUN WAI - SANTA CLARA CA, US
International Classification:
G06F017/60
US Classification:
705/014000
Abstract:
A method, apparatus, and article of manufacture for targeting information content, such as advertising, in overlapping sales territories. In one embodiment, a user accesses a web site and is assigned a cobrand. The cobrand is assigned based upon a uniform resource locator (URL) determined from data received from the user during access of the web site. If the determined URL does not correspond to a cobrand, the user is assigned an implicit cobrand. If the determined URL corresponds to a cobrand, the user is assigned an explicit cobrand. Advertising content based upon the assigned cobrand is selected and displayed to the user.

Receptacles And Kits, Such As For Dry Powder Packaging

US Patent:
2009003, Feb 5, 2009
Filed:
Sep 26, 2006
Appl. No.:
12/083079
Inventors:

B65D 17/50
US Classification:
206438, 220260
Abstract:
A receptacle () includes a holder () forming a cavity () that holds a pharmaceutical (), a lid (), and adhesive () that forms a bond () between the holder () and the lid (). As an example, the bond () has a shape that includes a protrusion () that facilitates removal of the lid () from the holder (). A kit () includes a plurality of containers containing powder including amphotericin B and pharmaceutically acceptable excipient. The kit () also includes an aerosolization apparatus () and instructions. As an example, the pharmaceutical composition is made from panicles including amphotericin B having a mass median diameter less than about 3 μm, such as from about 1.1 μm to about 1.9 μm.

Receptacle For An Aerosolizable Pharmaceutical Formulation

US Patent:
2011027, Nov 17, 2011
Filed:
Dec 4, 2008
Appl. No.:
12/745365

Abstract:
An article for storing a pharmaceutical formulation. In one or more embodiments, the present invention comprises a receptacle () for an aerosolizable formulation, the receptacle having a wall thickness of between about 100-235 microns, wherein the receptacle is puncturable to allow escape and dispersion of the formulation therein. Also provided are methods of aerosolizing formulations for inhalation, and systems for aerosolizing such formulations.

Termination Of A Pseudowires On Multiple Line Cards

US Patent:
2012025, Oct 11, 2012
Filed:
Apr 11, 2011
Appl. No.:
13/084531
Inventors:
Vijayan Ramakrishnan - Milpitas CA, US
Sami Boutros - San Ramon CA, US
Leo Chun-Chuen Chan - Los Altos CA, US
Reshad Rahman - Ottawa, CA
Sundar Siddaramaiah Bettadahalli - Fremont CA, US
Sivakumar Subramaniyan Ganapathy - Fremont CA, US
Assignee:
Cisco Technology, Inc., a corporation of California - San Jose CA
International Classification:
H04L 12/56
US Classification:
370392
Abstract:
In one embodiment, line cards of packet switching or other network devices are configured for terminating pseudowires. Typically, this includes multiple line cards being configured for terminating a same pseudowire, which allows the corresponding pseudowire traffic to be received by any one of these multiple line cards. Each of these pseudowire-terminating line cards is typically configured to apply one or more features to a pseudowire packet. Examples of these features include, but are not limited to: Access Control List, Quality of Service, Netflow, and Lawful Intercept. For a received packet to be sent out one of these pseudowires, a two-stage lookup operation can be used to first identify the pseudowire over which to forward the packet; and a second lookup operation based on the pseudowire to identify forwarding information corresponding to a path through a network over which a corresponding pseudowire is configured.

Method And Apparatus For An Accelerated Radius Search

US Patent:
6108650, Aug 22, 2000
Filed:
Aug 21, 1998
Appl. No.:
9/138185
Inventors:
Elon Musk - Palo Alto CA
King-Sun Wai - Santa Clara CA
Leo Chan - Belmont CA
Assignee:
MyWay.com Corporation - Andover MA
International Classification:
G06F 1730
US Classification:
707 4
Abstract:
A method and apparatus for performing an accelerated radius search. A search category is built having a density value corresponding to a geographic area. A first search radius is generated based upon the category, and the first search radius is used to perform a first search. If the first search returns an insufficient number of results, a second search radius is generated by using an heuristic to increase the first search radius, and the second search radius is used to perform a second search. The search is repeated until a desired results set is returned.
