Abstract: A brick-and-mortar merchant may receive a commission when a user interacts with an item at the brick-and-mortar merchant but later purchases the same or similar item from another source such as an online retailer. Interaction between the user and the brick-and-mortar merchant may be determined by geolocating a mobile device near or within a location of the merchant. In some embodiments, the online retailer may refer a customer to retail partners that may offer the item for viewing. The online retailer may track and compensate the retail partner for interacting with a user when the user visits the retail partner's location and possibly receives sales help and then later obtains the item from the online retailer.

Abstract: A sensor system includes a pressure sensor portion, and an accelerometer. Outputs from the sensor system are handled by a signal processing system that includes a first beamforming module for inputs from a pressure sensor, a second beamforming module for inputs from an accelerometer, and an adaptive beam interpolation module. A method for signal processing signals from both a pressure sensor and an accelerometer. An array of sensors transfers data wirelessly.
