Abstract: In a combined GPS/altimeter device, the calibration and hence the accuracy of barometric altimeter measurements are enhanced with the aid of derived altitudes from a GPS. The device determines the need for calibration and perform the subsequent computations necessary to facilitate the calibration. Furthermore, the device determines a correction quantity that should be applied to barometric altitude readings, thereby allowing the device to be calibrated while in motion. Both of these features ultimately result in a more accurate determination of altitude.

Abstract: A personal training device (10) adapted to assist a user in reaching performance goals, navigating, and accumulating performance statistics. In a preferred embodiment, the device broadly comprises a housing (10); an attachment mechanism (30); a GPS component (40); a user interface (50), including an input portion (52) and an output portion (54); a processor (60), including a timer (62) and a memory element (64); a data interface (70), including an input portion (72) and an output portion (74); an audio component (80); and a power supply (90). The device (10) is adapted to store goal information, monitor performance using GPS-derived data, and communicate performance information.

Abstract: A pail assembly for transporting two materials is disclosed. The pail assembly includes a pail for containing one of the materials, a container with a closure for containing the second material, a lid assembly with a receptacle molded into the lid assembly for closing the pail and supporting the container for the second material and a lid for closing the receptacle on the lid assembly.
