摘要： A system for and a method of managing a communications network (6) through the use of multiple network connections. The system prepares at least two transport service providers of a node (4) for establishing a network connection with corresponding transport service providers of another node (4) and associates the at least two transport service providers with each other and with a requesting application (30). The system monitors network connection condition and determines availability and suitability of each network connection. The system selectively transmits information via a selected network connection. The system seamlessly establishes the multiple connections and transmits the information over the selected network connection and is transparent to the application (30).

摘要： Switching power supplies for low power circuits. Power supplies described and disclosed herein comprise a linear regulator (180) for regulating an input power to this power supply, a flyback regulator (220) with three modes of output control comprising indirect sense feedforward, feedback, and override control. Indirect sense feedforward responds to changes in input voltage. The feedback responds to changes in output voltage with use of both of these wide variations in input voltage and output load can be tolerated. The override control takes over during abnormal conditions such as startup and short circuit. Switching power supplies described herein have high efficiencies and provide efficient power management, especially in low power budget applications.

摘要： Imbalances between currents to and from a remote point are detected by passing the outgoing currents and the return current through different, oppositely-oriented coils on a saturable core, and an excitation current is applied to another coil in the same core sufficient to drive the core into saturation in at least one direction. When the outgoing and return currents are the same, the excitation produces successive voltage pulses of the same durations, as measured by an up-down counter ; if an imbalance is present, the remainder in the up-down counter shows this. To detect excessively high imbalances, which might place the core always in saturation, another counter preferably senses the sum of the widths of successive pulses, and indicates an imbalance if this sum falls below a preselected threshold.
摘要翻译：通过使输出电流和返回电流通过可饱和磁芯上的不同的相反方向的线圈来检测来自远端点的电流之间的不平衡，并且激励电流被施加到相同磁芯中的另一个线圈以足以驱动磁芯在至少一个方向上达到饱和。当输出和返回电流相同时，激励产生相同持续时间的连续电压脉冲，如通过升降计数器测量的; 如果存在不平衡现象，余下的数据显示。为了检测可能使核心始终处于饱和状态的过高的不平衡，另一个计数器优选地感测连续脉冲的宽度的总和，并且如果该和低于预选阈值则指示不平衡。

摘要： The ratio C₁/C₂ between the capacitances of two capacitors is obtained by connecting them into the frequency-determining circuit of an oscillator in at least three different combinations, namely C₁ alone, C₂ alone and both or neither of C₁ and C₂; the resultant oscillation frequencies are measured, and a signal representative of changes in C₁/C₂ derived from the oscillator frequencies, preferably by means of digital circuitry. In one preferred mode C₁/C₂ is obtained by forming signals proportional to and in another preferred mode proportional to In still another preferred mode C₁/C₂ -1 is obtained from the expression T₁-T₃/T₂-T₃ and used as the indication of changes in C₁/C₂. In the foregoing, f₁, f₂, f₃ and f₄ are the oscillator frequencies produced respectively by connecting C₁ alone, C₂ alone, neither C₁ nor C₂, and both C₁ and C₂ into the frequency-determining circuit, and T₁, T₂, T₃ and T₄ are the periods of oscillations at f₁, f₂, f₃ and f₄ respectively.

摘要： A monolithic pressure transducer has a plurality of capacitive sensors (C R ,C A ,C S ). The capacitors are formed from the same silicon substrate and are equally affected by temperature variations, including temperature gradients. The capacitive sensors respectively sense temperature, absolute pressure, and differential pressure. A mode state machine (100) sequences the measurement of the capacitors under the control of a microprocessor (24) which forms the ratios between measurements from the temperature-sensing capacitor and each of the other two capacitors. The capacitors have a common electrode (89) which has portions forming diaphragms (80,94) associated with the absolute and differential pressure-sensing capacitors.
