Abstract: A technique for providing user-oriented promotions includes linking a good or service to an expert solution in which a user has potential interest. Alternatively, the expert solution itself may be a service. Matching the goods or services to the expert solution can result in improved targeting of users who may be interested in purchasing the good or service. If the expert solution itself is treated as a service, users with potential interest in the expert solution can be targeted in a similar manner. This can be further improved by maintaining user-specific information related to each user.

Abstract: A method and system for selecting and presenting advertisements and promotions to a user based on one or more tasks that is of interest to the user is disclosed.

Abstract: A technique for providing targeted information to users involves using demographic or specific user data. Each user may have some demographic data associated with them, which may be compared to, by way of example but not limitation, another user, a product, information, a location, or other goods or services. Promotions that take demographic information into account can be effective in presenting information to a user, which is more beneficial to both the user and a vendor or expert associated with the promotion. Specific user information can be used to address specific user needs.

Abstract: Embodiments of a system, method and computer program product for purchasing items are described. In one embodiment, information is obtained about one or more items of interest to a plurality of users. For each item, the number of users that identify the item as an item of interest is determined. Negotiations are conducted with a seller of the item for a discounted price for a number of items at least equal to the number of users determined to identify the item. A coupon is then sent to the users that identify the item as an item of interest. The coupon permits the purchase of the item at the negotiated discounted price.

Abstract: Embodiments are described for a system, method and computer program product for presenting advertising alerts to a user based on items of interest to the user. In one embodiment, information is obtained about one or more items of interest to a user. For each item, the user is permitted to select whether to receive advertising alerts relating to the item. Subsequently, a determination may be made as to whether a promotion is available for an item selected to receive advertising alerts. When a promotion is available, the user is presented with an advertising alert about the promotion.

Abstract: Embodiments of a system, method and computer program product for finding customer orientated Ads are described. In one embodiment, buyer's information is obtained about one or more items of interest to a buyer. For each item, the buyer's information may comprise information identifying the item and information about one or more characteristics of the item. Seller's information is then selected to present to the buyer according to the buyer' information. The buyer's information may comprise information identifying the item, Ads, promotions, coupons, product release, information about one or more characteristics of the item.

Abstract: Embodiments of a system, method and computer program product for organizing items of interest for presentment to a user are described. In one embodiment, information is obtained about one or more items of interest to a user. For each item, the obtained information includes information identifying the item and information about one or more characteristics of the item. For each item, the user is permitted to assign the item to one or more categories of need. The items are categorized into a plurality of lists according to the assigned categories of need. The plurality of lists are presented to the user so that the user can review items assigned to the same category of need in the list associated with the given category of need.

Abstract: A CMOS differential amplifier is provided comprising a current supply coupled to a first terminal of a power supply. A first CMOS transistor is provided having a first source, a first gate, and a first drain coupled to the current supply. A second CMOS transistor is also provided having a second source, a second gate, and a second drain coupled to the current supply. The first and second gates are inputs to the CMOS differential amplifier. A resistance is coupled between a second terminal of the power supply and the first source of the first transistor and the second source of the second transistor to improve common-mode and ground noise suppression.

Abstract: In this invention an integrated operational amplifier is calibrated to optimize phase margin. The calibration is done to correct changes caused by operating temp and supply voltages as well as process variations and aging that can affect the stability of the amplifier. A calibration circuit measures the response of the operational amplifier to a pulse input and controls a feedback impedance to produce an optimized phase margin. The output response to the pulse input is measured at two different times, at a first time close to the transition capturing the peak overshoot from an under damped amplifier and at second time later than the first measurement when the distortions from the under damped ringing have diminished. A quantizer circuit compares the two measure voltages and provides an input to control logic which selects the amount of reactance in the feedback of the operational amplifier.
