摘要： A charge balanced feedback type transmitter generates charge packets representative of a sensed parameter. Improved performance is achieved by the additiion of resistance connected between a charge packet generating reactance and an integrator to reduce the effects of noise caused by switching transients and by ground noise which is coupled to the charge packet generating circuitry by stray capacitance. The charge packets are integrated by the integrater, and the integrator output is supplied from a selective basis to the input of a comparator. The output of the comparator is used to control the application of charge packets to the integrator to achieve charge balance. The input of the comparator is selectively connected to the output of the integrator, to a first supply voltage, or to a second supply voltage to ensure a stable output of the comparator at a critical time when charge is being supplied to the integrator.

摘要： A wireless mesh network routes messages between a host computer and a plurality of field devices. The mesh network is synchronized to a global regular active schedule that defines active periods when messages can be transmitted or received by nodes of the network, and inactive periods when messages cannot be transmitted or received. Based upon messages to be sent by the host computer to selected field devices, the network is controlled to selectively maintain active those nodes required to route messages to the selected field devices. Those required nodes are maintained in an active state as long as communication with the selected field devices continues, while other nodes are allowed to return to a low power inactive state. When communication between the host computer and the selected field devices is no longer required, the entire network is allowed to enter the low power inactive state.
