Publication number: 20240086829Abstract: Systems and methods for identifying options for order fulfillment using an API are provided. The system receives, via the API, an order inquiry comprising customer information and item information about an item sold via a merchant website. The order inquiry can be received in response to a customer placing the item in an electronic shopping cart. The item information includes an item identifier and a quantity. The customer information includes a customer address. Using the item information and the customer information, the system identifies warehouse nodes and carriers via which the item can be delivered to the customer. The system confirms inventory of the item in the warehouse nodes. For each warehouse node with sufficient inventory, the system identifies shipping options for the item, including levels of service, cutoff order times, and prices. The system then generates fulfillment options for the item and provides the options to the merchant website.Type: ApplicationFiled: September 9, 2022Publication date: March 14, 2024Inventors: Bryan Absher, Michael Thanh-Hung Hotan, Seth Daniel Johnson, Megan Marie Quintero, Steven Stevenson, Halim Khoury

Publication number: 20190369657Abstract: The subject technology provides for removing a source of delay in a phase-locked loop (PLL) by causing the output rising edge to occur at the same time as the input rising edge. The subject technology replicates the amount of delay experienced along an input reference signal path to the PLL as close as possible using a same circuit configuration and bias circuits as in the input reference signal path. For example, a timing alignment circuit containing a replica circuit adds compensation delay to a negative feedback loop signal to match the feedback loop delay with the reference path delay. The delay of the reference signal path is estimated and added into the replica circuit. The delay characteristics of these two paths negate one another such that the phases of the input reference signal and the feedback loop signal become phase-locked at the input to the PLL.Type: ApplicationFiled: June 4, 2018Publication date: December 5, 2019Inventors: Michael Dean WOMAC, Jan-Michael STEVENSON, Richard William EZELL

Patent number: 8279101Abstract: High conversion rates are achieved in an analog to digital converter by tailoring the substrate type to specific operational elements of the converter. Embodiments place sample and hold processing circuitry on a substrate type having properties that allow for faster processing at high sampling/clock frequencies. Other operational elements of the converter are constructed on at least one other substrate type in keeping with the remainder of the circuitry for which the converter is being implemented. The sample and hold substrate may be implemented on any material which is capable of faster processing, such as silicon germanium, gallium arsenide, silicon bipolar, BiCMOS, and the like. Other portions may be implemented on a more CMOS substrate. Such systems and methods are able to implement analog-to digital conversion for broadband signals at high speeds without the need for extensive timing compensation, while also avoiding problems due to noise from further digital processing circuitry.Type: GrantFiled: November 11, 2010Date of Patent: October 2, 2012Assignee: CSR Technology Inc.Inventor: Jan-Michael Stevenson
