摘要： A key for a user can be created according to at least one first image of the user. The key can be verified with at least one second image of the user captured after the key is created. A visitor can be authenticated according to a first measure of similarity between the key and at least one authentication image of the visitor. The visitor is authenticated as the user if the first measure of similarity is greater than a first predetermined threshold. The key can be refined with the at least one authentication image of the visitor if the first measure of similarity is lower than the first predetermined threshold and the visitor is authenticated as the user based on a password.

摘要： An apparatus for detecting lock status of a spread spectrum signal, having a first accumulator, a first calculation unit, a second calculation unit, a second accumulator, a multiplier and a comparator. The first accumulator accumulates an in-phase integration result and a quadrature integration result over a time period. The first calculation unit determines a first evaluation value based on the accumulated in-phase integration result and the accumulated quadrature integration result. The second calculation unit processes the in-phase integration result and the quadrature integration result. The second accumulator accumulates the output of the second calculation unit over the time period. The multiplier determines a second evaluation value by multiplying the accumulated result from the second accumulator with a predetermined value. The comparator compares the first and second evaluation results wherein the comparison result is an indicator of the lock status.

摘要： A navigation system for detecting error on Doppler frequencies of a plurality of satellite signals measured by the navigation system is disclosed herein. The navigation system includes an offset calculator for calculating offsets of the Doppler frequencies of the satellite signals during a predetermined time period and calculating an average value of the offsets. The navigation system further includes an error detecting unit coupled to the offset calculator. The error detecting unit compares the offsets of the Doppler frequencies of the satellite signals with the average value of the offsets and determines whether the satellite signals are unavailable according to corresponding comparison results.

摘要： An improved floating collar assembly for gas turbine combustion units consists of a sheet metal collar with a flat flange and an E seal that is pre-compressed within a block of epoxy. The collar fits over a corresponding fuel nozzle burner tube and is retained on a cap assembly by a flat plate. During assembly, the collar is loose so that it floats, which makes cap assembly easy. During operation, the epoxy used to pre-compress the E seal heats up and burns off, whereupon the E seal opens up and produces a seating load between the collar and plate that is high enough to keep the collar from rotating and thereby reduce collar wear.

摘要： An apparatus includes a socket, a computer-readable medium, and a controller. The socket is capable of interfacing with different types of storage medium. The computer-readable medium is operable for storing a computer-executable universal driver associated with a first operation mode and compatible with each of the types of storage medium, and for storing a computer-executable dedicated driver associated with a second operation mode and compatible with only a subset of the types of storage medium. The controller is operable for selecting a selected driver from the universal driver and the dedicated driver if a storage medium is inserted into the socket and for operating in a corresponding operation mode to exchange data information with the storage medium according to the selected driver. The selected driver includes the dedicated driver if the storage medium is a member of the subset and otherwise the selected driver includes the universal driver.
