Abstract: In some embodiments, techniques for processing an alert may include receiving a specification of a first location, creating an alert, associating the first location with the alert, determining a first current location as a second location, wherein determining the second location follows receiving the specification of the first location and precedes determining a third location, determining that the second location does not match the specification of the first location, determining a second current location as the third location, determining that the third location matches the specification of the first location, and presenting information relating to the alert.

Abstract: The transmission system transmits an encrypted identifier ultrasonically in an open-air environment using an ultrasonic transmitter. The ultrasonic identifier is associated with a location, which may be a store or a department within a store, and may be received by a microphone on a mobile phone. The identifier may be used to infer presence of the mobile phone user at the location associated with the identifier. The transmitter may include an ultrasonic transducer. The system may further provide a reward, responsive to inferring presence at the location.

Abstract: The presentment and redemption system offers discounts directly to consumers through their mobile phones. The discounts are based upon the user of the mobile phone meeting a targeting criterion and the discounts are determined using the targeting criterion. Mobile phone users that do not meet the targeting criterion are not eligible for the discount. Because the discounts can be targeted to each individual consumer, there can be a better correlation between consumers' interests and the transmitted discounts.

Abstract: The optimization system monitors a mobile phone user's behavior in response to an offer for a reward and determines a good level for a product promotion. The determination may be made based upon the user's current response, past response patterns to various reward levels or a correlation between a user's behavior and the behavior corresponding to a class of users. The system can determine an offer level that maximizes the return on the profit or revenue from a potential purchase for which the offer applies.

Abstract: In some embodiments, techniques for rewarding presence include detecting a presence of a mobile phone within an enclosed space, transmitting information relating to the presence of the mobile phone within the enclosed space to a server computer, wherein the server computer processes an award for the presence of the mobile phone within the enclosed space, wherein the award is associated with a user account associated with the mobile phone; and receiving from the server computer information relating to the award.

Abstract: The detection system monitors WiFi wireless communications at a wireless device and detects a probe request associated with a location. The WiFi device may be a dedicated presence detection device or may offer access to internet and other services as a WiFi access point. A device identifier associated with the originating device may be a component of the probe request. Using the device identifier, the system can detect the presence of a consumer at the location associated with the wireless communications device and transmit information to the consumer based upon the device identifier.

Abstract: In some embodiments, techniques for pricing may include detecting a visitor at an e-commerce site, determining that an item offered for sale at the e-commerce site is of potential interest to the visitor, detecting another e-commerce site at which the user has viewed the item, determining a historical price, wherein the historical price is associated with a web page, wherein the web page offered the item at the other e-commerce site, calculating an offering price, wherein the offering price is based on the historical price, offering the item to the visitor at the offering price, and selling the item to the visitor at the offering price.

Abstract: In some embodiments, techniques for electronic messaging may include various enhancements.

Abstract: In some embodiments, a technique for providing location-based functionality comprises providing functionality, wherein the functionality uses information provided by a location-aware device.

Abstract: In some embodiments, a subwoofer enclosure includes a substantially triangular first face, second face, third face, and fourth face, a first corner at an intersection of the first, second and third faces, a second corner at an intersection of the first, second and fourth faces, a third corner at an intersection of the first, third and fourth faces, a fourth corner at an intersection of the second, third and fourth faces, wherein an angle between the first corner and a midpoint between the third corner and the fourth corner, having the second corner as its vertex, is substantially ninety degrees, wherein an angle between the third corner and the fourth corner, having the second corner as its vertex, is substantially ninety degrees, and a subwoofer driver attached to the third face, having a free air resonant frequency less than one hundred Hertz.

Abstract: In some embodiments, techniques for searching comprise various enhancements.

Abstract: In some embodiments, techniques for computer security comprise reducing the deceptiveness of electronic communications.

Abstract: In some embodiments, a technique for logging an item encountered by a mobile device comprises automatically detecting an item in an uncontrolled environment, extracting an identity associated with the item, logging an encounter, wherein the encounter includes the identity, and deleting the encounter after a predetermined period of time has elapsed, wherein the encounter is not marked as relevant.

Abstract: In some embodiments, techniques for modifying a profile may include receiving a first profile data associated with a first user, associating the first profile data with a profile associated with the first user, receiving a second profile data associated with a second user different from the first user, and associating the second profile data with the profile.

Abstract: In some embodiments, techniques for voting and visual cryptography may include various enhancements.

Abstract: In some embodiments, a technique for logging an item encountered by a mobile device comprises automatically detecting an item in an uncontrolled environment, extracting an identity associated with the item, logging an encounter, wherein the encounter includes the identity, and deleting the encounter after a predetermined period of time has elapsed, wherein the encounter is not marked as relevant.

Abstract: In some embodiments, techniques for document integrity may include detecting an initiator associated with a key, detecting the end of a document, determining that no terminator matching the key has been detected, and rejecting all or part of the document. In some embodiments, techniques for document integrity may include generating a key and associating the key with an initiator insertion point and a terminator insertion point.

Abstract: In some embodiments, techniques for processing an alert may include creating or receiving an alert, determining a first current location, associating the first current location with the alert if not already so associated, determining a second current location, determining that the second current location matches the first current location, and presenting information relating to the alert.
