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： Audio bus receiver includes a pair of bipolar transistors each having a base coupled via a respective resistor to a respective bus receiver input terminal, each having an emitter that is diode coupled to a respective current source and each having a collector coupled via a respective load resistor to a source of reference potential. The emitters are coupled together via a gain control resistor and the collectors are coupled to an output terminal via a differential amplifier. Advantageously, the receiver avoids loading the bus under power-down conditions without requiring the use of stand-by power supplies. Additionally, high common mode rejection is achieved without need for precision matching of components and only a single supply voltage is required for operation.

摘要： In a video display system including a cathode ray tube (CRT) as a display device and video output amplifiers for amplifying relatively low level red, green an blue video input voltages to produce respective relatively high level video output voltages suitable for application to the CRT, a "black tracking" circuit is coupled to the inputs of video output amplifiers. Voltage to current converters are utilized as preamplifiers for the video output amplifiers. The "black tracking" circuit includes terminating resistors connected at one end to respective outputs of the voltage to current converters for converting output currents of the converters to respective ones of the low level video input voltages, and a common resistor connected between the other ends of the terminating resistors and a signal ground point. A filter capacitor is connected in parallel with the common resistor. A common "black tracking" voltage representative of the average picture level of a reproduced image is developed across the common resistor and, as a result of the connection to individual ones of the terminating resistors, is added to each one of the low level video input voltages at the inputs of respective ones of the video output amplifiers.

摘要： A method and apparatus are provided for recovering multiphase modulated data. A signal pulse of a fixed duration is generated upon the transition of a first phase component of a multiphase modulated signal transmitted at a fixed bit rate. A data clock signal having a frequency in synchronism with the bit rate is generated in response to an error signal. The data clock signal is delayed by a delay of approximately one half the duration of the signal pulse. The delayed clock is gated using the signal pulse to provide the error signal that establishes the data clock frequency. Components of the multiphase signal are sampled using the phase locked data clock to recover data.

摘要： Method for multiplexing inbound and outbound calls from a call center to improve the efficiency of call center agents since an idle agent can sometimes place an outbound call rather than wait for another inbound call. A parameter k is used to have an ACD agent place an outbound call instead of waiting to receive an inbound call. Specifically, if more than k agents in an inbound/outbound ACD call group are idle, and no calls are in the inbound call queue, then, in accordance with the present invention, callback or outbound calls are assigned to idle ACD agents until k agents are idle. For example, in a preferred embodiment of the present invention, callback calls will be assigned to an ACD agent before outbound calls. Note that, in accordance with the present invention, at any instant, at most k agents will be idle, because as soon as k+1 agents are idle, an agent will be assigned to a callback or to an outbound call.

摘要： A differential current source (50) provides first and second complementary output currents (I1, I2) responsive to a video input signal (S1) which are coupled via respective load networks (52,54) to a common supply terminal (22) and develop first and second complementary video output signals (V1,V2). A first output circuit (56) applies the first output signal to a first output terminal (16) via a voltage follower transistor (Q6) and applies the second output signal to the first output terminal via a current source transistor (Q8). A second output terminal (18) is similarly driven by a second voltage follower transistor (Q5) and a second current source transistor (Q7), all transistors being of the same conductivity type. A tri-state control circuit (Q1,Q2) coupled to the differential current source enables the differential current source in a first operating mode to produce the first and second complementary currents whereby push pull output signals are produced at the output terminals. In a second operating mode, the tri-state control circuit forces the complementary currents to zero whereby the common supply terminal (22) applies turn-off bias via the two load networks to the control electrodes of all of the output transistors thereby "tri-stating" (isolating) the output terminals. Advantageously, in the tri-state mode, there is zero quiescent power dissipation in the output circuits, the load networks, the differential current source and the tri-state control circuit.

摘要： A baseband television signal having a video portion with a suppressed horizontal sync pulse is descrambled by using a variable attenuator. The attenuator shifts the level of predetermined portions of the signal to restore the suppressed horizontal sync pulse to a normal unsuppressed level with respect to the rest of the signal. A reference voltage is derived from a blanking level potential and sync level potential of the signal, and is equal to the zero carrier level of the video portion of the signal. The reference voltage is utilized to maintain the level of the restored sync pulse at a proper value.

摘要： Apparatus for automatically and/or manually controlling setup of a device such as a color television camera. The system includes a closed loop automatic setup system which provides at least one setup control signal to the camera and, during a specific automatic setup operation, responds to at least one video signal provided by the camera to automatically adjust the level of the setup control signal. A manual control is also provided which permits manual variation of the level established by the auto setup system. In addition, apparatus is included for disabling the manual control during the automatic setup operation so that at that time the setting of the manual control does not influence the level of the setup control signal. The apparatus is also operable in fully automatic and fully manual modes.
