A bandwidth adjustable transimpedance amplifier. The bandwidth adjustable transimpedance amplifier includes a feedback path with a selectable resistance. The bandwidth adjustable transimpedance amplifier is preferably implemented with a photodiode in a five pin package for an optical transceiver system, with a single pin providing a monitor out function and a rate select input.

Variable bandwidth transimpedance amplifier with one-wire interface

An automatic power control circuit for a laser driver includes precharge circuitry to precharge inputs to a comparator receiving an indication of laser output power, for example from a monitor photodiode. The precharge circuitry can be selectively activated when a laser driven by the laser driver is operating in burst mode, as opposed to operating in continuous mode. In addition, a digital up-down counter may be used to increase or decrease a digital value used to set a bias level for the laser, with the digital up-down counter counting up if the comparator indicates the laser output is too low and counting down if the comparator indicates the laser output is too high.

Digital automatic power control loop for continuous and burst mode applications

A computer-assisted method for evaluating a cluster assignment for an observation is disclosed. The disclosed method includes, for each of a plurality of observations, obtaining a data set containing no more than one proxy value for each of a plurality of variables, each variable having a plurality of possible values, the data set also containing a cluster assignment for the observation, the cluster assignment identifying one cluster from a plurality of clusters. The disclosed method also includes, for each observation from the plurality of observations, calculating a percent of proxy values for the plurality of variables that equals a mode of that observation's corresponding cluster's proxy values for the corresponding variables, and outputting the percent for each observation.

Method and system for clustering optimization and applications

A system and method for biasing the outputs of a laser modulator driver while allowing for high speed operation. A differential amplifier type modulator driver is provided which uses a reduced number of components in the high speed path. Additionally, the modulator driver may be constructed with a distributed output stage.

Differential opto-electronics transmitter

Exemplary embodiments provide a computer-assisted method for typing customers/prospects, including the activities of: refining a survey via bestfit clustering; refining survey results via composition analysis; and identifying clusters of customers/prospects from the survey results via champion/challenger cluster refinement and panel analysis.

Method, system, and device for typing customers/prospects

A computer-assisted method for determining a plurality of clusters is disclosed. The disclosed method includes, for each of a plurality of observations, obtaining a data set containing no more than one proxy value for each of a plurality of variables, each variable having a plurality of possible values. The disclosed method also includes, assigning each of the plurality of observations to one of a plurality of clusters, and, for the plurality of observations and the plurality of variables, via cluster reassignment, maximizing a processor-determined fitness score representing a number of variables from the plurality of variables for which each observation's proxy value corresponds to a mode for that observation's assigned cluster.

A computer-assisted method is disclosed for determining a potential effectiveness of a survey question. The disclosed method includes segregating a plurality of responses to a survey question into a plurality of categories, and determining a response distribution for each of the plurality of categories. The disclosed method also includes calculating a box score and a difference score for the survey question from the response distributions, and using the box score and the difference score to obtain an effectiveness score for the survey question.

Computer-assisted systems and methods for determining effectiveness of survey question

A computer-assisted method for placing each of a plurality of observations into one of a predefined set of clusters is disclosed. The disclosed method includes, for each of a plurality of observations, obtaining a data set containing no more than one proxy value for each of a plurality of variables, each variable having a plurality of possible values, and obtaining a set of first dummy variables having a value indicative of an observation's membership or non-membership (i.e., membership status) in a particular cluster. The disclosed method also includes obtaining a set of second dummy variables each having a value indicative of an observation's having a particular response or lack thereof for a given variable, and, for each observation, regressing the set of first dummy variables on the set of second dummy variables to obtain a linear approximation to a plurality of probabilities that an observation with particular provided values to the plurality of possible values belongs to each particular cluster from the predefined set of clusters.
