Abstract: The memory card is comprised of memory that stores a user name and password for each respective network address or universal resource locator (URL). The information is encrypted to preclude unauthorized access to the memory. A controller controls operation and access to the card. A bus interface couples the card to various buses, such as a universal serial bus. When the card is attached to an electronic device that is accessing a particular URL, the consumer enters the password or other unlock request information. Once the unlock request is validated, the user name and password associated with that particular URL is transmitted to the browser on the electronic device that is requesting the information.

Abstract: In a remote unit receiver capable of demodulating a plurality of signal instances corresponding to a singe remote unit transmitted signal, a first instance of a signal is demodulated to produce a first set of energy values corresponding to a set of possible data values of the signal. A second instance of the signal is demodulated to produce a second set of energy values corresponding to the set of possible data values. The first and the second sets of energy values are then combined to determine a combined set of energy values. A first estimate of a most likely transmitted data value is determined based upon the combined set of energy values An energy level of the first instance is determined based upon the energy value within the first set of energy values corresponding to the first estimate of the most likely transmitted data value.
