摘要： A driver for a cathode ray tube includes a black level compensation circuit which generates an offset voltage which tracks the current flowing to the output of the driver and therefore the average picture level (APL). The offset voltage is added as a component of the output voltage so as to increasingly shift the output voltage toward black as the APL increases. This compensates for CRT gamma non-linearities and for light scattering effects which might otherwise cause the loss of perceived detail and sharpness in dark areas of a high APL image. In the disclosed embodiment, the driver comprises a cascode amplifier and the offset voltage generating element includes a capacitively bypassed resistor connected in a reference voltage network connected to the emitter circuit of the lower (common emitter configured) transistor of the cascode amplilfier.

摘要： An amplifier (10) includes several output devices (12, 14), each of which is connected to a power source providing a different supply voltage. The inputs and outputs of the devices are coupled to the same signal input (V.sub.in) and output (V.sub.out). The device (12) operated from the lower supply voltage generates the lower level output signals and operates at a relatively high level of efficiency. When higher level output signals are called for, the device (14) operated from the higher supply voltage becomes active. The input of the lower level device is connected to the signal input through a circuit (16) which decouples the device input from the signal input when signals are present on the signal input which would force the device into saturation. The speed of operation of the amplifier is thus enhanced, since saturation of the lower level device (12) is prevented.
摘要翻译：放大器（10）包括多个输出装置（12,14），每个输出装置连接到提供不同电源电压的电源。器件的输入和输出耦合到相同的信号输入（Vin）和输出（Vout）。从较低的电源电压运行的装置（12）产生较低电平的输出信号并以相对较高的效率来运行。当要求更高电平的输出信号时，从较高电源电压运行的器件（14）变为有效。低电平装置的输入通过电路（16）连接到信号输入端，电路（16）将信号输入端上的信号与信号输入端分离，从而使装置饱和。因此，由于能够防止下位装置（12）的饱和，所以能够提高放大器的运转速度。

摘要： A system and method for predicting the wait time of a caller to a call center is disclosed. The call center associates a set of agents to which the caller may be queued. This set of agents selected may depend on the skills that each agent possesses, the type of service request made by the caller, caller priority, time of day, day of week and other conditions. An initial wait time estimate may then be given to the caller who is just queued. As a caller's conditions may dynamically change, a caller's position in the queue may also change as well as the pool of available agents. Periodic wait time estimate updates may also be given to the queued caller. A caller's wait time may be estimated based upon mean inter-arrival times for recently past calls into the call center. An average inter-arrival time may be calculated for the last several calls. Alternatively, a caller's wait time may be estimated based upon calls that are recently queued and dequeued. A table of values, Wnj, are maintained wherein each such value denoting the jth recent wait time of calls arriving with n calls already in the queue. An average value, Wn, for each n among all such Wnj, is thus calculated and a caller's estimated wait time is thus given, depending on how many calls are in the queue at the time of calling.

摘要： A method for dynamically allocating the capacity of a computer network. All users of the network are classified as low or high priority users. High priority users may broadcast a delay message to the low priority users that cause the low priority users to delay before attempting to use the network. The length of delay can be adjusted if the high priority users are not able to utilize the network as required. In addition, if a low priority user does not receive a broadcast delay message within a predetermined amount of time, the delay period is reset to avoid unnecessary slowing of the network.

摘要： An adjustable gamma correction circuit that is operative to adjust grey scale distortion in a projected video signal by dynamically changing the gamma transfer function without the need to reset projector high and low amplification thresholds. The circuit includes both a linear amplification stage and a non-linear amplification stage that function to reshape the projector transfer function. At the non-linear stage consists of two pairs of emitter coupled amplifiers set at different voltage thresholds. The two pairs of emitter coupled transistors allow adjustment of the grey level of the circuit transfer function to thereby compensate for mid-level variations in the projector transfer function, thereby resulting in improved projected image quality.

摘要： A driver circuit especially for driving scan velocity modulation (SVM) coils or similar loads is characterized by low quiescent current loading and high peak output. The driver is coupled to an input signal varying between a quiescent signal level and a peak signal level. A transistor is coupled to a power supply and to the input signal, so as to conduct according to the input signal. A nonlinear element such as a diode is coupled in series with the emitter-collector junction of the transistor, and is biased to a voltage slightly less than a forward biased conducting diode voltage drop. Thus the diode has a higher resistance when the transistor is conducting at the quiescent signal level, and a lower resistance when the transistor is conducting at the peak signal level. The quiescent bias conditions are maintained by resistors in series and parallel with the diode. The driver may be configured as a complementary push-pull stage.

摘要： A preamplifier for use in an imaging system including a charge-injection device employs an amplifier, at least a first switch and a clamping loop. The switch is capable of grounding the amplifier reference outside the blanking interval and is open during at least a portion of the blanking interval, thereby preventing the amplifier from entering saturation during the charge injection performed by the charge-injection device. The clamping loop serves to maintain the output of the preamplifier at a predetermined constant level during that portion of the blanking interval in which the amplifier is disabled. The inventive preamplifier has a reduced input impedence and capacitance, and thus operates with less overall noise.
