Background calibration of random chopping non-idealities in data converters
Random chopping is an effective technique for data converters. Random chopping can calibrate offset errors, calibrate offset mismatch in interleaved ADCs, and dither even order harmonics. However, the non-idealities of the (analog) chopper circuit can limit its effectiveness. If left uncorrected, these non-idealities cause severe degradation in the noise floor that defeats the purpose of chopping, and the non-idealities may be substantially worse than the non-idealities that chopping is meant to fix. To address the non-idealities of the random chopper, calibration techniques can be applied, using correlators and calibrations that may already be present for the data converter. Therefore, the cost and digital overhead are negligible. Calibrating the chopper circuit can make the chopping more effective, while relaxing the design constraints imposed on the analog circuitry. |

In a three-phase, four-wire electrical distribution system, a zig-zag transformer and at least one Cascade Multilevel Modular Inverter (CMMI) is coupled between the distribution system and the neutral. A controller modulates the states of the H-bridges in the CMMI to build an AC waveform. The voltage is chosen by the controller in order to control an equivalent impedance that draws an appropriate neutral current through the zig-zag transformer. This neutral current is generally chosen to cancel the neutral current sensed in the line. In other embodiments, the chosen neutral current may be based on a remotely sensed imbalance, rather than on a local value, determined by the power utility as a critical load point in the system. The desired injection current is then translated by the controller into a desired zero-sequence reactive impedance, based on measurement of the local terminal voltage, allowing the controller to regulate the current without generating or consuming real power. In some embodiments, the zig-zag transformer is omitted. |

Active matrix organic light emitting diode panel
The present disclosure provides an active matrix organic light emitting diode panel where a color shift does not occur at an edge of a display area. A color shift does not occur at the edge of the display area in an AMOLED panel proposed by an embodiment of the present disclosure to avoid color shift phenomenon at the edge of a display area. So red, green, and blue (R, G, and B) pixel units that are not arranged in a regular pattern at a non-standard pixel structure and a corresponding anode material layer are in a floating state. So the color shift phenomenon will not occur. When the pixel unit of the non-standard pixel structure receives an image display control signal, the color shift phenomenon may occur due to the inability to correspondingly display a corresponding image corresponding to the image display control signal to display the screen normally. |

Systems and methods of package container return
A package container includes a body, a cover, a cover lock, a user interface, and an electronic controller. The electronic controller includes a memory and a processor. The processor is configured to store order information in the memory. The order information indicates that the package container is assigned to transport one or more items. The processor is configured to detect, at a first time, that the cover has moved from a closed state to an open state. The processor is also configured to store a trial start time that is based on the first time. The processor is configured to, based at least in part on receiving a return request via the user interface and detecting that the cover is in the closed state, store a second time as a trial end time and send a transportation request to a delivery management server to initiate transportation of the package container. |

Packet delivery management
A computer device and computer automated method for supporting packet delivery. A packet to be delivered has a designated delivery address and recipient. On approach of a delivery vehicle carrying the packet to the delivery address, when a geo-fence close to the delivery address is crossed, it is checked whether it is possible to deliver the packet to the designated delivery address. If it is not possible, then the method selects, conditional on sensing proximity to the designated delivery address with reference to the computing device's current location, from among one or more possible delivery addresses which have been pre-registered by the recipient as local addresses of friends an alternative delivery address at which a friend is currently located with reference to a mobile device registered to that friend. If a suitable friend who is at home is found, then the packet is delivered to the friend. The delivery is then confirmed, notifying the recipient of delivery of the packet to the alternative delivery address. |

Method and system for optimizing distribution of incentive budget for additional time interval allocation in a multi-week work schedule
A computer-implemented method for optimizing distribution of incentive-budget for additional time interval allocation in a multi-week work schedule is provided herein. The computer-implemented method comprising: (i) training a model to forecast future net staffing; (ii) generating a multi-week work schedule; (iii) using the model to forecast for each time interval a net staffing value; (iv) classifying time intervals as understaffed; (v) displaying the understaffed time intervals to suggest agents to take as additional time interval; (vi) providing a tier incentive structure and an incentive budget to be updated by a user; (vii) training the model to forecast a degree of elasticity of agents demand for each time interval based on historical agents schedule changes; and (viii) calculating a combination of incentives of each tier of the tier incentive structure in the incentive-budget to accommodate understaffed time intervals and maximize agents demand for time intervals based on forecasted degree of elasticity. |

Generating product decisions
The present invention relates to a system and method for generating business decisions. Embodiments of this system and method receive customer transaction data and additional information (cumulatively referred to as ‘modeling data’). This data is utilized to generate a product decision tree which models consumer purchasing decisions as a tree structure. The product decision tree may be utilized by the system to analyze demand for a given leaf (product) in association with other related products. In some embodiments, customers are segmented into groupings of customers who have similar attributes, including similar shopping behaviors. Customer insights are generated for the customer segments. The customer insights and the product decision tree are used to generate business plans, which may then be provided to a store for implementation. These plans may include a product assortment plan, an everyday pricing plan, a promotional plan, and a markdown plan. |
