Abstract: The present invention provides a method for a handheld computer with a graphical display showing multiple points of data in real-time from a microcontroller-driven analog measurement instrument via a low speed, wired or wireless transport. A finite amount of measurements are taken at a predetermined interval from a sensor wherein the measurements are converted into a digital word using an Analog to Digital converter and a high speed microcontroller performing all the timing operations to read the sensor. The measurements read from the Analog to Digital converter are then stored in a signal buffer where mathematical transformations, such as integrations and domain conversions are done on the signal buffer as instructed from software running on a client machine. Once the desired transformations are complete either all or a contiguous subset of the measurements are scaled to an array of integers that denote display coordinates in a predetermined viewing area on the clients LCD display.

Abstract: The present invention provides a method and system suitable for managing battery power recharging of a handheld measurement system that combines a handheld computer or PDA and a measurement sled. The software consistently monitors both the charge levels of the PDA and sled during recharging by monitoring a difference in recharge needs to give priority to either the handheld computer and/or sled for recharging wherein a recharge need is determined by monitoring a charge level of a corresponding device wherein the charge level is compared to a predetermined threshold level that is set within a sled's microcontroller-based software. Thus, as one of the charge levels passes above its corresponding charge threshold recharge needs may become equal commencing simultaneous recharge at the latter porting of system recharging. This allows for the low charge levels to be exclusively recharged from the external power source at the beginning of the recharge cycle making for a time efficient recharge cycle.
