摘要:
Methods and systems are provided for biometric sensing. An illumination subsystem provides light at discrete wavelengths to a skin site of an individual. A detection subsystem receives light scattered from the skin site. A computational unit is interfaced with the detection system. The computational unit has instructions for deriving a spatially distributed multispectral image from the received light at the discrete wavelengths. The computational unit also has instructions for comparing the derived multispectral image with a database of multispectral images to identify the individual.

A satellite positioning system receiver programmed to determine information for a satellite using ephemeris data (710), determine information for the same satellite using almanac data (722), which may have been previously stored on the receiver, to determine an error between the satellite information determined from the ephemeris data and the satellite information determined from the stored almanac data (730), and to update the stored almanac data based upon the error (734).

A method (200) and apparatus (900) for correcting frequency errors of received signals in a wireless communication receiver are disclosed. The wireless communication device (900) receives (204) a signal; correlates (206) the received signal with the plurality of offset prestored data sets; generates (208) at a predetermined data rate interval a plurality of signal correlations where each of the plurality of correlations is correlated to each of the plurality of offset prestored data sets; and computes (210) a frequency error estimate based upon the plurality of signal correlations.

Multiple links with series resistors are connected to address select transistors and a sense line in a printhead encoding circuit. This arrangement provides an increased number of possible states, thereby increasing the amount of information which can be encoded for such purposes as pen identification.

摘要:
A satellite positioning system receiver programmed to operate synchronously with an expected time of arrival of information from at least one satellite of a satellite positioning system, and to receive the information from the at least one satellite when the receiver is operating during the expected time of arrival of the information. In one embodiment, the receiver operates synchronously with an expected arrival of specific subframe information from at least one satellite of a satellite positioning system, and receives the specific subframe information when the receiver is operating.
