Abstract: A device for acquiring first and subsequent images of a suspect area on a patient and methods for monitoring or detecting changes of the suspect area over time and providing notification when the changes exceed a threshold. The device may be an imaging device, such as a digital camera, possibly augmented with physical or optical devices for arranging the orientation and/or distance of the imaging device with respect to the suspect area. In addition, methods for identifying, relocating, acquiring a first and/or subsequent image of the suspect area, and performing a comparative analysis of respective images are also described. Results of the comparative analysis can be used to notify and/or assist a medical professional in treating or counseling the patient.

Abstract: Images, audio, biometric information, and other data is captured by a user device. The captured data is sent to a server that pre-processes and then decodes the captured data to identify its contents. Once identified, the captured data is associated with a function string that specifies a function and parameters that correspond to the captured data. The function is called and executed to provide information back to the user device that is relevant to the captured data, or to initiate other operations. The relevant information to return to the user device can include product information, translations, auction data, electronic device settings, audio, and others. Operations that may be initiated include software registration, people searches, or user authentication to allow access to restricted services.
