US Patent:

6405175, Jun 11, 2002

Filed:

Jul 27, 1999

Appl. No.:

09/361545

Inventors:

David Way Ng - Redwood City CA 94065

International Classification:

G06F 1760

US Classification:

705 14, 705 26, 705400

Abstract:

A web site on the world-wide-web allows users to search a product/price database. The database contains product and price information for a wide variety of products from many different suppliers such as online and offline stores. Information in the database is collected and corrected by submitting users who are rewarded for product submissions. A submitting user inputs data on new product, price, supplier, or rating information using an online form. The user highlights coordinates of the model, make, and price on the suppliers web page, so that automated software can later check the suppliers web page for price and product updates. The submitting user is rewarded for submitting product and price information. When other consumer-users search the database and find the product, the submitting user is again rewarded. When these other consumer-users follow a link to the suppliers web page for that product, the submitting user is further rewarded.

Filed:

Jul 8, 1999

Appl. No.:

09/350040

Inventors:

David Way Ng - Redwood City CA 94065

International Classification:

G06F 1130

US Classification:

713156, 709228, 705 14, 705 26

Abstract:

Electronic mail (email) is certified and authenticated by an authentication service. The authentication service is integrated with an email web site that allows users to set up email accounts. Outgoing email from the email web site is routed to the authentication service. A message identifier (ID) is generated and added to the message within markers. A random-number generator creates random pad characters that are added to the message before a checksum is generated. The checksum and the pad characters are stored in a table indexed by the message ID. The pad characters and the checksum are placed in secure storage and not available to users or others on the Internet. The email with the message ID in the markers but without the pad characters or checksum is sent to the recipients, along with instructions on how to authenticate the message. Others can authenticate a message by emailing it to the authentication service. The message ID is extracted from the markers and used to find the checksum and pad characters in the table.

Jose P. Pereira - Cupertino CA

Assignee:

NetLogic Microsystems, Inc. - Mountain View CA

International Classification:

G11C 1500

US Classification:

365 49, 365236

Abstract:

Entry relocation in a content addressable memory (CAM) device. The CAM device is instructed to store a first value and to supply an address at which the first value is stored. If the address indicates that the first value has been stored within an overflow storage array of the CAM device, the CAM device is instructed to store the first value again.

International Classification:

G06F 12/00

US Classification:

711108, 711158, 707 6, 370392, 365 49

Abstract:

A hierarchical programmable-priority content addressable memory (CAM) system including first, second and third CAM devices. The first CAM device has a first priority number output and a first enable input. The second CAM device has a priority number input and an enable output coupled to the priority number output and the first enable input, respectively, of the first CAM device. The second CAM device also has a priority number output and an enable input. The third CAM device has a priority number input and an enable output coupled to the priority number output and the enable input, respectively, of the second CAM device.

Appl. No.:

11/498130

Inventors:

David R. Ng - San Jose CA, US
Michael G. Negrete - Palo Alto CA, US

Assignee:

Linear Technology Corporation - Milpitas CA

International Classification:

H02M 3/335

US Classification:

363 2112, 363 97

Abstract:

A regulator may include a load voltage sensing circuit configured to generate a feedback signal representative of output voltage from an isolated flyback converter. The regulator may include a pulse generator configured to controllably generate the pulses and to increase at least one off time and at least one period of the pulses after a load on the flyback converter decreases.

International Classification:

H02M 3/335

US Classification:

363 2117, 363 2109, 363 97

Abstract:

System and methodology for controlling output current of switching circuitry having an input circuit and an output circuit electrically isolated from each other. A value of the output current may be determined based on input voltage, input current and reflected output voltage representing the voltage in the input circuit which corresponds to the output voltage. A switching element in the input circuit is controlled to produce the determined value of output current.

Appl. No.:

10/904958

Inventors:

David Ng - Redwood City CA, US

International Classification:

G06F 7/00

US Classification:

707100000

Abstract:

An Internet search engine ranks search results based on popularity with mobile-device users. Geo-position data from cell phones and other mobile devices are collected into a device geo-position database. The geo-position data is compared to locations of businesses in a business database. When a mobile device's geo-position moves inside a business location, a traffic counter for that business location in the business database is updated. When an Internet user performs a local search, the result set is sorted based on a rank that is at least partially determined by the traffic counters. The popularity-ranked search results indicate which businesses received the most mobile-device visits, an indication of the business's overall popularity. The popularity ranking may be adjusted for business size by dividing the traffic counter by the square footage of the business and sorting the result set based on the mobile-device visits, or repeat visits, per square foot.

Appl. No.:

Inventors:

David Ng - Redwood City CA, US

International Classification:

G06Q 99/00

US Classification:

705001000

Abstract:

A shipping redirection interface allows a seller to change the destination address while a package is in-transit. The seller orders a product from a low-cost overseas factory, inputs the seller's address as an initial destination and begins shipment on a slow container ship. A schedule generator calculates an optimistic estimate of the package's arrival at the intermediate hub that redirects the package so the seller can plan when to redirect. While the product is slowly crossing an ocean on the ship, the seller may sell the product to a buyer such as through an online auction. The seller enters the buyer's address as the new destination address and redirects the product at the intermediate hub after the product is unloaded from the ship. The delay from sale to the buyer until the buyer receives the product is reduced without warehousing the product. Unsold products are delivered to the seller.
