Abstract: Methods and apparatuses for computing a variance between two business metrics is described. In one embodiment, the method computes a variance for each of a first set of activities based on the corresponding reference state of that activity, wherein the variance for an activity is the change in contribution for that activity between the first and second business metrics and with each of the first set of activities having a reference value. Furthermore, the method computes a variance for each of a second set of activities based on the corresponding start and end values of that activity with each of the second set of activities having a start and end value.

Abstract: Methods and apparatuses for computing a variance for the difference between two business metrics. In one embodiment, the method accesses a response model and a plurality of activities with start and end values for each of the plurality of activities. Furthermore, the method computes a variance for the difference between the first and second business metrics for each of the plurality of activities using the response model by setting that activity to one of the corresponding starting and ending values and setting others of the plurality of activities to the value state opposite of that activity, wherein the variance for an activity is the change in contribution for that activity between the start and end sales volumes.

Abstract: A voice activated music controller system, useful in association with a game system and a player is provided. The voice activated music controller system includes a voice activated controller, and a base station. The voice activated controller includes a transducer for receiving an audio signal, one or more sound effect controls, and a transmitter. The sound effect controls may be any of buttons, touch pads, roller balls, accelerometers and pressure sensors. The transmitter sends the audio signal and the control inputs to a receiver of the base station via a radio signal. A signal processor in the base station applies one or more sound effects to the audio signal according to the control inputs. These sound effects include one or more of a chorus effect, a pitch modulation, a pitch correction, a harmonizing effect, and a sound bite. This results in the generation of a processed audio signal which is outputted to the gaming system via a coupler.

Abstract: Methods and apparatuses for decomposing a business metric based on a plurality of activities and a response model are described. In one embodiment, the method accesses the response model and the plurality of activities, the plurality of activities each having a reference and executed value. The method computes a contribution to the business metric based on setting one of the plurality of activities to one of the corresponding reference and executed value and setting the other activities to the value state opposite of that activity. Furthermore, the method computes each of the contributions independent of the response model type.

Abstract: An improved weight distribution sensory device with integrated controls is provided. Such a weight distribution sensory device, often referred to as a balance platform, may include a chassis for supporting a user, pressure sensors and control sensors coupled to the chassis, and a processor. The pressure sensors generate pressure data regarding the compression force from the weight of the user on the chassis. The control sensors are located on a forward dorsal portion of the chassis, and may generate control data when manipulated by the user. The control sensors include at least one proximity sensor which senses object proximity (such as the user's foot) in a narrow band above the sensor along the y-axis. The processor may then receive the pressure data and the control data, and may generate a total weight of the user and a weight distribution of the user, and action data for the user by cross referencing the weight distribution with the control data.

Abstract: An improved linear motor is provided useful in conjunction with audio equipment for reduced distortion audio output at high voice coil displacements. The improved linear motor may include a yoke, a gap plate which forms an air gap with the yoke, magnets coupled to the yoke and the gap plate, a former, and a voice coil coupled to the former. The magnets generate a magnetic field across the air gap, which is relatively narrow. The former and coil fit in the air gap and may move in a vertical direction. The voice coil includes more than one segment, each having differing electrical resistance. The differing resistances cause the force on the voice coil to be uniform regardless of displacement of the voice coil vertically within the air gap. Resistance differences between the segments may be caused by differing the wire lengths making up each segment of the coil. Likewise, each segment may be made of differing material to vary resistance.

Abstract: A system and method for price and promotion response analysis is provided. Such a system is useful for a business to analyze the forecasted lifts associated with changes in price and promotion activity. The system sets the configuration of the response report, which includes price change and promotion change intervals. Promotions include temporary price reductions, displays, ads and multiples. Modeling data is received for the products. Forecasts, both non-cannibalistic and cannibalistic, are generated for the sales of the products dependent upon the price change and promotion change intervals. Forecasts include at least one of product forecasts, demand group forecasts, line level forecasts and category level forecasts. Suspect forecasts below a minimum confidence may be flagged. Confidence matrices may be generated which reflect accuracy of the forecasts. The response report may be generated by collecting the forecasts and the confidence matrices according to the configuration of the response report.

Abstract: A method for creating a sales model for a plurality of products is provided.
