A personal portable integrator is used to integrate the services of an arbitrary audio delivery device such as an MP3, CD, DVD, radio, or other media player, with the services of an arbitrary two-way communication device such as a mobile phone, or a two-way radio such as a walkie talkie, citizen band radio (e.g. CB), HAM radio, marine or aviation radio, and the like. The portable integrator receives and provides input and output signals from both the audio delivery device and the two-way communication device, thereby enabling a user to listen to music or other audio material and receive and place phone calls on a mobile phone simultaneously. The portable integrator provides these services by switching between the audio and communication devices, mixing signals received therefrom, and optionally enabling a user to reduce the volume or mute the signals as desired.

The present invention is a switching power converter that supports both a boost mode of operation and a buck mode of operation, uses one energy storage element, transitions smoothly between boosting and bucking, and avoids simultaneous boosting and bucking. The switching power converter uses a common duty-cycle timing signal and a common duty-cycle setpoint signal to provide a smooth transition between boosting and bucking, and to eliminate overlap between boosting and bucking. A voltage input error integrator is used to integrate out errors between an output voltage and a setpoint voltage to provide the common duty-cycle setpoint signal. Duty-cycle error integrators are used to integrate out errors between the common duty-cycle setpoint signal and the actual duty-cycle of either the buck converter or the boost converter. Non-overlapping boost operating and buck operating ranges are provided by the common duty-cycle setpoint signal.

A database integrator is provided to an application program that utilizes the ODBC interface so as to enable the application program to access the data in a legacy DBMS. The application program ("the client program") is located on a workstation, and the legacy DBMS is located on a host computer. The legacy DBMS is used primarily by an application program ("the server program"). The database integrator receives ODBC commands from the client program, and unlike database drivers interacting with non-legacy DBMSs that send SQL statements to the DBMS, the database integrator instead converts these commands into server program-specific commands to manipulate the user interface of the server program, establishes a connection with the server program over a terminal emulation session, and issues the server program-specific commands to the server program by using the terminal emulator. These server program-specific commands manipulate the server program's user interface to display the appropriate data so that the database integrator can then access it. In this manner, the database integrator accesses the data in the legacy DBMS indirectly by issuing user interface commands to the server program, because the database integrator cannot typically access the legacy DBMS directly. This indirect access enables the client program to gain access to the data in a database that it would not otherwise be able to access.

An Orthogonal Frequency Division Multiplexing (OFDM) receiver that employs N second-order phase-lock loops sharing a common integrator (where N is the number of pilots in the system). The N second order phase-lock loops track out independent pilot phase rotations to facilitate the constructive averaging of the pilots' phase information. At the same time, by sharing a common integrator, the OFDM receiver takes advantage of noise averaging over multiple pilots to obtain a cleaner frequency offset estimation. The OFDM receiver may also compensate for FFT window drift by calculating a phase difference between a selected pair of pilots and tracking the rate of change of the calculated phase difference over time. The calculated phase difference is used to control the position of an upstream FFT window after a predetermined phase difference threshold is exceeded. The tracked rate of change is used to continuously adjust the phase of downstream equalizer taps.
