Abstract: A system and method for testing multiple smart card devices in parallel and asynchronously are provided. The system includes a smart card module that may be easily inserted in a digital test system. The smart card module includes multiple smart card instrument channels, each one of which testing a separate smart card device independently and asynchronously from the others. The smart card instrument channels employ a novel modulation technique based on palette waveforms that are formed of transitions between two data bits.

Abstract: A positional flow sensing device includes an accelerometer or inclinometer with user readable indicators for tracking information associated with a succession of fluid flow events. The fluids can be any fluid that it may be desirable to monitor the dispensing of, such as beer, other beverages, or oil. Each fluid flow event volume is calculated based on control valve positional information, upon which the positional flow sensing device is installed. The positional flow sensing device is operatively coupled to a user interface having a display and grouping of switches arranged to provide to the user fluid volume related information during and after each fluid flow event.

Abstract: A digitizer can be programmed to digitize an ANALOG signal with a complex frequency pattern determined in response to set of trigger signals. The digitizer includes an addressable packet memory storing a set of data packets and produces one of its stored data packets as output when addressed. The output data packet includes both PERIOD and MODE data fields. The digitizer also incudes an analog-to-digital converter for digitizing the ANALOG signal at the frequency controlled by the PERIOD data output of the packet memory. The MODE data output of the packet memory tells a trigger logic circuit how to choose a next packet memory address and selects one of the trigger signals to tell the trigger logic circuit when to change the packet memory address so as to alter the digitizing frequency.
