  • Publication number: 20200342395
    Abstract: This application relates to apparatus and methods for determining, assigning, and displaying order deliveries. In some examples, a computing device may obtain order data identifying at least one order for delivery during a timeslot. The computing device may transmit, to a driver's computing device, a request for deliveries for a first price during the timeslot. The computing device may receive, from the driver's computing device, a response accepting the request. The computing device may then assign the driver to the order, and determine a delivery status based on the assignment of the first driver to the first order. The delivery status may identify, for example, that the order has been assigned to the driver, an estimated delivery time, the number of items being delivered, the weight of the items, and a route taken by the driver. The computing device may also display the delivery status.

  • Publication number: 20200342558
    Abstract: This application relates to apparatus and methods for determining delivery prices for, and the assigning of, order deliveries. In some examples, a computing device may obtain order data identifying an order for delivery. The computing device may transmit a request to deliver the order for a first price to a first driver. The computing device may determine that a response to the request has not been received, and obtain risk values corresponding to identified delivery request acceptance risk factors. The risk factors may include location based risk factors, delivery time risk factors, driver supply risk factors, and time deadline risk factors. The computing device may determine a second price based on the first price and the risk values by executing one or more algorithms. The computing device may then transmit another request to deliver the order for the second price to a second driver.

  • Publication number: 20200013862
    Abstract: A semiconductor device having a back-side field plate includes a buffer layer that includes a first compound semiconductor material, where the buffer layer is epitaxial to a crystalline substrate. The semiconductor device also includes field plate layer that is disposed on a surface of the buffer layer. The semiconductor device further includes a first channel layer disposed over the field plate layer, where the first channel layer includes the first compound semiconductor material. The semiconductor device further includes a region comprising a two-dimensional electron gas, where the two-dimensional electron gas is formed at an interface between the first channel layer and a second channel layer. The semiconductor device additionally includes a back-side field plate that is formed by a region of the field plate layer and is electrically isolated from other regions of the field plate layer.

  • Publication number: 20150317720
    Abstract: Control or prevention of usage of an online ecommerce system to transfer funds by evaluating proximity between a location where cash payment is made and a location where a cash refund is requested. When the proximity exceeds a distance threshold, the cash refund at the second location is prohibited, and when the proximity is less than the distance threshold, the cash refund is permitted. Various embodiments ask the customer to specify a choice of refund stores, evaluate whether the person who made the cash payment for the order is different than the person who requested the refund, require identification, check publicly available Internet social site information for a relationship between the people, check for a pattern of requesting refunds, limit the refund to store credit, or a combination thereof.
