Adaptive Coordinated Medium Access Control (AC-MAC), a contention-based Medium Access Control protocol for wireless sensor networks. To handle the load variations in some real-time sensor applications, ACMAC introduces the adaptive duty cycle scheme within the framework of sensor-MAC (S-MAC).

The STWD100 watchdog timer circuits are self-contained devices which prevent systemfailures that are caused by certain types of hardware errors (non-responding peripherals,bus contention, etc.) or software errors (bad code jump, code stuck in loop, etc.).The STWD100 watchdog timer has an input, WDI, and an output, WDO (see Figure 2). Theinput is used to clear the internal watchdog timer periodically within the specified timeoutperiod, twd (see Section 3: Watchdog timing). While the system is operating correctly, itperiodically toggles the watchdog input, WDI. If the system fails, the watchdog timer is notreset, a system alert is generated and the watchdog output, WDO, is asserted (seeSection 3: Watchdog timing).The STWD100 circuit also has an enable pin, EN (see Figure 2), which can enable ordisable the watchdog functionality. The EN pin is connected to the internal pull-downresistor. The device is enabled if the EN pin is left floating.

The zlibex.pas unit included in this archive will work with delphi 5, 6,and 7. if you previously downloaded my delphi 5 unit, you will notice that the unit has been renamed. this was done because borland included in its delphi 6 and 7 lib directories a zlib.dcu file and i felt it was more correct to rename my unit and force developers to have to update their code than to make developers worry about the possible file contention in delphi 6 and 7.
