Abstract: A computer-implemented system and method are provided for automatically determining rebate eligibility for purchased products. In one example, the purchased products may be travel-rebated products such as booked air travel itineraries. A database stores purchase information associated with purchased products purchased at corresponding purchase prices. A product administration system having a computer software-based product administration application interacts with the database and purchase information of a first purchased product is compared with purchase information of subsequently purchased products. The product administration application interacts with the database to determine if the first purchased a product matches a subsequently purchased product based on a set of matching criteria.

Abstract: Publicly accessible linking information is to establish a trusted relationship between reciprocally linked entities controlling web resources, such as websites or web logs. A method of establishing a trust relationship between two entities identifying a user-installed link to a second web resource in a first web resource. Next, the method determines when a reciprocal link is made in the second web resource directed to the first web resource and creates a trust relationship between the entities based on the reciprocal link.

Abstract: An application providing a common interface allowing access and login to a electronic mail system and instant messaging system. The application allows responding to an email using an instant message, replying to an instant message using an email, sending and receiving both email and instant messages from one application, sending email attachments instantly, and displaying presence information for the user, user email contacts and user messenger contacts. Alerts are provided for both emails and instant messages received. The inbox vies can automatically be refreshed when a user receives new email. An interface is provided to convert multiple email contacts into messenger contacts. The system can be used with both local messenger clients and browser based IM clients.

Abstract: An email manager for an inbox directs emails to various categories based on importance assigned by an email recipient and provides a user interface for presenting emails to the recipient in groups prioritized by importance. In one implementation importance is based on the sending source and in one implementation importance is based on content.

Abstract: Subject matter includes systems and methods for presence-based messaging. In one implementation an engine detects the real-time presence of a potential message recipient who can be reached via a communications medium that a sender composing a message is not currently using. The engine can either transition to an environment for composing and sending the message using the detected presence-based communications medium or offer the sender a choice of switching to the presence-based communication medium.

Abstract: Social network email filtering is described. A user's address book includes a first group of email addresses. Those email addresses are used to identify address books that include another group of email addresses. Multiple iterations may be used to identify several groups of email addresses, representing a user's social network. When an email message addressed to the user is received, the message is trusted if the sending email address is within the user's social network. Otherwise, the message is flagged as junk mail. Varying trust levels may be applied to messages that are received based on a distance within a social network between the sending email address and the user and/or how often the sending email address appears within the social network.

Abstract: An electrocardiographic amplifier having an integrator in the feedback loop between the amplifier's input and output whose time constant is varied by the duty cycle of a series switch to vary the low frequency 3 dB roll-off point as a function of the detected low frequency noise in the amplifier output signal. A capacitor is switched in parallel with the inverting feedback resistor to lower the high frequency 3 dB roll-off point in response to detected high frequency noise.
