Abstract: A sigma delta modulator includes a sigma delta modulating loop and a plurality of adjusting loops. The sigma delta modulating loop processes an input signal and an adjustment signal based on a first clock signal, so as to generate a quantized output signal. The first clock signal has a clock cycle. The sigma delta modulating loop has a first delay time that is the same as M times of the clock cycle. M is an integral multiple of 0.5 and is larger than 1. The adjusting loops delay the quantized output signal for second delay times, respectively, so as to generate the adjustment signal.

Abstract: The functions and capabilities of a computer are improved by programming the computer to provide market demand forecasts for a new product that are more accurate than forecasts generated using conventional approaches. A demand forecast for a new product is generated by pairing or associating a set of one or more existing products with the new product, receiving historical sales data for the existing product, separating the historical sales data into a plurality of discrete components, constructing a respective feature-based predictive model for each of corresponding components of the plurality of discrete components, generating a corresponding prediction from each respective feature-based predictive model for each of the plurality of discrete components, and aggregating each corresponding prediction for each of the plurality of discrete components to generate the demand forecast for the new product.

Abstract: Embodiments of the present invention provide efficient and dynamic systems and methods for building a hybrid road network and grid based spatial temporal index to handle big trajectory data. Embodiments of the present invention can be used to satisfy the issue of low indexing and compression rate of big trajectory data, and to improve the efficiency of index queries, while also providing a mechanism to account for missing road links in a map.

Abstract: An electrical connector comprises: an insulative housing and a plurality of terminals retained in the insulative housing. The insulative housing has a base portion and a mating tongue. The mating tongue comprises a stepped portion extending from the base portion and a tongue portion extending from the stepped portion. The insulative housing defines an outer periphery. The stepped portion defines a front face. The base portion defines a rear face. The terminal defines a connecting portion buried in the base portion and the stepped portion, a contacting portion extending from the connecting portion. The insulative housing defines a sealing member filling in the periphery of the connecting portion. The sealing member not extends out the front face of the stepped portion, the rear face of the base portion and the out periphery of the insulative housing. It is favorable for improving the waterproof effect of the electric connector.

Abstract: A pump device includes a casing, an impeller, a base, and a motor. The casing includes a pump chamber, and an inlet and an outlet. The impeller is accommodated in the pump chamber. The motor is connected to the casing for driving the impeller to rotate and includes a rotor chamber for receiving a rotor. The base is disposed between the impeller and the motor and includes an accommodating groove having an inlet port in communication with the rotor chamber to allow fluid in the pump chamber to enter into the rotor chamber. In the pump device, precipitation has been performed to fluid in the accommodating groove before the fluid enters into the rotor chamber, thus the impurity particles can be prevented from entering into the rotor chamber, thereby prolonging the service life of the pump device.

Abstract: A method and system optimizing source selection of an online order with the lowest fulfillment cost by considering multiple types of parameters, including shipping costs, backlog costs and markdown savings of the order. The method includes obtaining an order from the order retrieval subsystem of the OMS, selecting the candidate sources, and retrieving data from retailers or shipping companies of each selected candidate sources. The system then calculates the costs and savings parameters of the candidate sources from the retrieved data. The system identifies all possible candidate sourcing selections of the order and calculates the total fulfillment cost of each sourcing selection of the order by adding the shipping costs with the backlog costs, and subtracting the markdown savings of all candidate sources in each sourcing selection. The system identifies the optimized sourcing selection of the order with the lowest fulfillment cost and renders the selection to the OMS.
