This invention solves the problem of what to do with the valve cap when it is removed from the valve while checking tire pressure. The base includes two base plates coupled to each other. The scheduling information includes hierarchical design schedule blocks which accurately depict the timing and scheduling of the nested blocks of the design. Event reports are then stored at the customer data centers in response to occurrences of the predefined operational events. A plurality of switches are controlled by logic to define a discharge mode, a charge mode and charge sharing mode in which a plurality of capacitive elements share charge while generating the input voltage to the oscillator. Network-based systems are also disclosed.
