Embodiments include a system for forecasting demand data for new products. The system and method may include generating a phase-in group profile based on similar products. The phase-in group profile may have multiple demand profiles for low, medium and high demand variations. These demand profiles may be applied to new products in the same phase-in group to generate a forecast profile.

A method and apparatus to efficiently round requested quantities to efficient transportation quantities in the supply chain. Target locations are organized in a sequence. A tolerance interval around the requested quantity is calculated for each target location. The requested value is then rounded to an efficient transportation quantity for each target location in its sequential order.

A light emitting diode (LED) driver for an LED backlight of a color-sequential liquid crystal display (LCD) and method for operation thereof includes a plurality of LED strings having one or more LEDs emitting light at wavelength corresponding to a predetermined color. A plurality of switches is respectively coupled to the plurality of LED strings. A current source is switchably coupled respectively and sequentially to each of the plurality of switches by control signals to open and close the switches in a pattern that illuminates the LED strings. The switches are opened and closed sequentially to permit a respective LED string to provide an output of the predetermined color for a specific period of time such that a total output of the plurality of LED strings provides an output having the desired overall color perceived through temporal integration of an output of each respective LED string.

A driver circuit (10) for a light emitting diode comprises a first driver circuit (32, 32′, 32′) for generating a first current output for driving the light emitting diode, wherein the first driver circuit has a control switch for interrupting the supply of the first current output. A second driver circuit (50) is for generating a second current output for driving the light emitting diode, and the second driver circuit also has a control switch for interrupting the supply of the second current output. The overall output of the driver circuit comprises a pulse width modulated output current which alternates between a high current (Ihigh) generated by the first driver circuit and a low current (Ilow) generated by the second driver circuit. By providing separate driver circuits for two different current requirements, the circuits can be optimised for each function. For example the high current value can comprise an LED operation current, and the low current value can comprise a non-zero measurement current.

The invention relates to calibrating light emitters (4). In order to avoid blanking of a backlight and also to reduce the number of light sensors (14), it is possible to drive a plurality of light emitters to the pulsed initial driving condition (PWM1-PWM4), shift a start time (T0, T3) of the initial driving condition of a selected one of the light emitters temporally in front of start times (T1, T2) of remaining light emitters, detecting an illumination condition produced by the selected one of the light emitters at the beginning (T3) of a subsequent shifted driving condition of the selected one of the light emitters, determining an adjustment factor for the selected light emitter by comparing a detected illumination condition with a calibration illumination condition, and respectively supplying the selected light emitter with a modified driving condition comprising the initial driving condition modified by the adjustment factor.

Systems and methods are disclosed for redeploying stock between inventory locations. The systems and methods may include receiving a redeployment indication indicating stock to be redeployed and determining, based on the redeployment indication, the first inventory location for receiving the stock and the second inventory location for redeploying the stock. Further, the systems and methods may include determining a cost-benefit value based on a savings value and a move cost value, wherein the savings value reflects an amount to be saved if the stock was redeployed from the second location to the first location and wherein the move cost value reflects a cost for redeploying the stock from the second location to the first location. Finally, a determination to deploy the stock may be made by comparing the cost-benefit value to, for example, a redeployment threshold value.

Systems and methods are disclosed for distributing stock in a distribution network. The distribution network may include a source location and a plurality of target locations. In the disclosed systems and methods, the stock requirements of the target locations may be categorized into a plurality of requirement types, wherein each requirement type reflects a category of stock requirements for one of the target locations. In addition, the plurality of requirement types may be prioritized by order of importance and/or the plurality of target locations may be prioritized for each requirement type based on at least one sequence rule. Based on the prioritized requirement types and/or prioritized sequence of the target locations, the stock may be distributed to the plurality of target locations.
