Appl. No.:

09/615110

Inventors:

International Classification:

A61K 922

US Classification:

424473, 424468, 424469, 424470, 424486, 424488, 514781, 514782, 514784

Abstract:

The present invention is directed to an active agent dosage form which is adapted for retention in the stomach and useful for the prolonged delivery of an active agent formulation to a fluid environment of use. The active agent dosage form is a polymer matrix that swells upon contact with the fluids of the stomach. A portion of the polymer matrix is surrounded by a band of insoluble material that prevents the covered portion of the polymer matrix from swelling and provides a segment of the dosage form that is of sufficient rigidity to withstand the contractions of the stomach and delay expulsion of the dosage form from the stomach until substantially all of the active agent has been dispensed.

Abstract:

The present invention is directed to an active agent dosage form which is adapted for retention in the stomach and useful for the prolonged delivery of a liquid, active agent formulation to a fluid environment of use. The liquid, active agent formulation is sorbed into porous particles that are dispersed in a polymer matrix that swells upon contact with the fluids of the stomach. A portion of the polymer matrix may be surrounded by a band of insoluble material that prevents the covered portion of the polymer matrix from swelling and provides a segment of the dosage form that is of sufficient rigidity to withstand the contractions of the stomach and delay expulsion of the dosage form from the stomach until substantially all of the active agent has been dispensed.

International Classification:

G06F 15/16

US Classification:

709206, 709202, 709203

Abstract:

The disclosure describes systems and methods for determining spam. A spam detecting system identifies potential spam messages by checking the relationship between a sender of a message and a recipient of the message. The spam detecting system identifies the relationship between the sender and recipient as ‘unknown’ or ‘trusted’. If the message is ‘trusted’, the message is transmitted accordingly to the recipient. If the message is classified as ‘unknown’, then the message is analyzed in view of other identified potential spam messages where a count is tallied against a threshold value to keep track of the probability a message is spam.

Abstract:

Embodiments are directed towards employing a plurality of single use passwords to provide phishing detection and user authentication. A user receives a plurality of single use passwords that expire within a defined time period after having been sent to a registered device. During a login attempt, the user enters a user name and a requested one of the passwords, which once entered expires. If valid, the user then enters a portion of another password to complete a displayed portion of a password, and a specified other one of passwords. If the displayed portion of the other passwords does not match any portion of one of passwords, then the user may detect a phishing attempt and terminate the login. If the user correctly the password data, the user may then access secured data. Each new login request requires a different set of passwords to be used.
