摘要： A high impedance attenuator for use in a test and measurement instrument employs compensation to adjust the low frequency attenuation to match the high frequency attenuation exhibited by the attenuator, rather than attempting to adjust the high frequency attenuation exhibited by the attenuator. In an alternate embodiment of the invention, compensation to adjust low frequency attenuation is employed in a feedback loop and an opposite compensation is applied in a parallel attenuation stage to stabilize the input resistance. In yet another embodiment of the invention, compensation to adjust low frequency attenuation is employed by means of an R-C time constant of an additional R-C circuit in a feed forward loop. This additional time constant is matched to the R-C time constant of the input R-C network. The input resistance of the attenuator is not changed.

摘要： Disclosed is an LED bulb having a current-compensated driving circuit. A compensation current 352 is coupled to a main driving capacitor used to power LEDs and functions to keep the load current more constant. This has dual advantages of saving power and making the light output more uniform. Saving power also means that the circuit runs cooler than without compensation. Additionally this circuit includes an inductor placed in line with a driving capacitor. The inductor functions to reduce rapid current influx to the capacitor during operation of the driving circuit, which reduces EMF and reduces component stress. One benefit of using an inductor is that most of the current absorbed by the inductor is provided back to the circuit during a later portion of the AC cycle, which also limits energy losses by the driving circuit.
摘要翻译：公开了具有电流补偿驱动电路的LED灯泡。补偿电流352耦合到用于为LED供电的主驱动电容器并且用于保持负载电流更恒定的功能。这具有节省电力并使光输出更均匀的双重优点。省电也意味着电路比没有补偿更冷。此外，该电路包括与驱动电容器成一直线放置的电感器。电感器用于在驱动电路运行期间减少快速电流流向电容器，从而减少EMF并降低元件应力。使用电感器的一个好处是，电感器吸收的大部分电流在AC周期的后期部分被提供回电路，这也限制了驱动电路的能量损耗。

摘要： A method by which a microprocessor based handheld multi-meter, or other handheld electronic instrument, can communicate with a computer or other microprocessor based device through the measurement input jacks of the handheld multi-meter. A handheld meter, thus equipped, can receive control or calibration data from, and provide test or calibration data to, a host computer or microprocessor based accessory or other instrument. To enable this capability, the handheld meter employs dual-signal, single-axis jacks, for example split banana jacks, for one or more of its signal and ground receptacles. The handheld meter and the computer, or another microprocessor based instrument or accessory device that the meter is to communicate with, are equipped with mutually compatible software and appropriate hardware to support single signal path communication.

摘要： A method and circuit for triggering an electronic instrument only once during a period of an input signal having multiple triggering events during that period. A signal applied to an electronic instrument, such as an oscilloscope, is acquired. Qualified triggering events occurring on the acquired signal are identified. A selected one of the qualified triggering events during the period of the applied signal causes a trigger signal output to occur, while other qualified triggering events are ignored. In the preferred embodiment a triggering event is qualified by a first comparator that compares the input signal to a first reference level and produces a predetermined logic level output if the input signal bears a predetermined relationship to the reference level. When a qualified triggering event occurs, a buffer amplifier applies the predetermined logic level to charge a capacitor, which thereafter stores some energy from the input signal and applies it to a comparator for a predetermined period of time. The comparator compares the voltage on the capacitor to a second reference level and produces a pulse if the capacitor voltage has a predetermined relationship to the second reference level. The leading edge of the pulse comprises a trigger output signal. Subsequent triggering events which occur before a predetermined period of time are unable to produce another trigger signal. Five alternative embodiments employing the same general principle as the preferred embodiment are disclosed.

摘要： An amplifier includes first and second transistors having emitters connected to a first current source, feedback from the second transistor collector to its base being supplied through a base-emitter path of a first Darlington pair in series with a first diode. A second current source is connected to the first Darlington pair emitter. Third and fourth transistors have emitters connected to a third current source with feedback supplied from the fourth transistor collector to its base through a second Darlington pair and a second diode. The second Darlington pair emitter is connected to a fourth current source and resistively coupled to the first Darlington pair emitter. Constant currents are supplied to the second and fourth transistor collectors and an input voltage across the first and third transistor bases controls allocation of current between the first and second Darlington pair emitter-collector paths to produce a differential output current proportional to the input voltage when both Darlington pairs are on. When the input voltage is highly negative, the first Darlington pair turns off and a biasing circuit reverse biases the first diode to prevent the second transistor from saturating and substantially discharging capacitance at the base of the first Darlington pair. Thus, the first Darlington pair can rapidly turn on when the input voltage is subsequently driven more positive. When the input voltage is highly positive, another biasing circuit reverse biases the second diode to prevent the fourth transistor from saturating.

摘要： Disclosed is an LED bulb having many advantages over previous bulbs. The bulb is designed with ease of fabrication and low cost in mind. A main support is made of chromed copper, used for both its reflectivity, its readily availability, and its relative low cost. A collection of bright LEDs are electrically coupled to a driving circuit formed on a board that is housed within the main support. The LEDs are mounted on a circuit board flexible enough to form into a desired shape while rigid enough to withstand normal movements. The LED circuit board includes multiple polished or shiny areas, also called lands or panels made to reflect light away from the bulb. The panels are electrically insulated from the operating circuit and prevent injury should the bulb be broken and the components be touched, even while operating.
