Abstract: The present invention provides an automatic identification and tracking method and system for identifying whether a customer is a very important person (VIP), retrieving profile, demographical data and/or point of sale (POS) records of the customer, tracking location of the customer, and sending the retrieved profile and tracked location of the customer to mobile devices of staffs, therefore enhanced services and targeted advertisements can be provided to customers promptly and accurately.

Abstract: The present invention comprises capturing an image of a subject to be authenticated; a step of face verification; followed by the process steps of a scan line detection test, a specular reflection detection test, and a chromatic moment and color diversity feature analysis test in no particular order. The method requires a subject to present her face before a camera, which can be the built-in or peripheral camera of e.g. a mobile communication device or a mobile computing device. The method also requires displaying to the subject certain instructions and the real-time video feedback of the subject face on a display screen, which can be the built-in or peripheral display screen of the mobile communication device or mobile computing device.

Abstract: A system architecture for facilitating wireless communications includes a processor configured to implement interference avoidance processing and interference control processing for one or more groups of devices of a packet-communications system. The interference avoidance processing provides different addresses and a common clock for each of the groups of devices to minimize a frequency collision probability for the devices. The interference control processing detects when a same frequency element is selected for more than one of the devices for a same time slot and implements rescue processing to save data packets that are going to collide from being lost. In a preferred embodiment, the interference avoidance processing includes choosing particular address bits to provide the different addresses.
