Multiple database queries are satisfied with the same data in a manner that assures the data is current and without having to interrogate the database for each query. A second electrical path in the primary circuit has the inductor coupled in series with a second primary winding and a second switch to the ground connection. The adapter receives a cylindrical post member of a fixture element on a fixture body. The multi-resolution lapped transform outputs transform coefficients, for example, first transform coefficients and second transform coefficients. The wireless transmitter may also be stationary or moving, and can be incorporated into structures such as a vehicle, a billboard, a building, a road sign, a traffic light, or the like. The light guide body has an incident surface for receiving the diverged light, and emitting surfaces for emitting light to the second solar cell panel.
