Publication number: 20240086897Abstract: Described is a hybrid centralized-decentralized system for managing data and token transactions among a decentralized group of stakeholders. The system uses a blockchain architecture to maintain secure identities for the stakeholders, as well as allow any stakeholder to perform a data or token transaction with another stakeholder. A central organization manages a central application and a data exchange. The central application manages profile data from users and interaction data for users with developer applications and provides it to the data exchange. The data exchange organizes and packages the data and may provide it to other stakeholders for analysis.Type: ApplicationFiled: November 26, 2023Publication date: March 14, 2024Inventors: Matthew Lindenberger, Luan Dang

Patent number: 10254378Abstract: The present disclosure provides methods, systems, and devices for tracking a mobile device in an indoor area or bounded area. A method for tracking a mobile device includes receiving sensor data from a mobile device and generating a heuristic map based on the sensor data describing a set of possible current locations of the mobile device in the bounded area. The method further includes receiving additional sensor data from the mobile device, and determining a change in position of the mobile device based on the additional sensor data. The method further yet includes updating the heuristic map to disqualify a first possible current location from the set of possible current locations, and outputting the updated set of possible current locations for display on a user interface.Type: GrantFiled: June 30, 2017Date of Patent: April 9, 2019Assignee: PHUNWARE, INC.Inventors: Luan Dang, Matt Lindenberger, Devin Pigera, Duy Nguyen, Dennis Griesser, Kent Tu, Tyler Prevost

Publication number: 20190079653Abstract: Methods and systems for interactive user interface objects are provided. The user interface allows for users to manipulate different objects represented by icons within a user interface, such as that of an iPhone or iPad or other touch screen devices. Users may bump objects together, flick one object towards another, bump an object against the edge of a screen, flick an object towards a certain area such as a dock, or otherwise manipulate the objects. The user's actions or manipulations of objects may result in an action by the objects or may have no effect. Depending on the compatibility of objects, the objects may be neutral towards one another, may attract each other, or may repel. The objects that attract may share content or communicate with each other via a one-time interaction, or may establish links or connections with each other that enable longer term communication or broadcasts that occur upon pre-determined triggers.Type: ApplicationFiled: March 30, 2018Publication date: March 14, 2019Inventors: Alan S.

Patent number: 9042173Abstract: Memory architecture, such as for a flash EEPROM memory embedded within a processor or other large scale integrated circuit, and including differential sense circuitry. The memory includes an array of memory cells in rows and columns, and organized into sectors, each sector split into portions. Columns of the array are grouped into small groups from which a final stage column decode selects a column from the group based on the least significant bits of the column address. Adjacent groups of columns are paired, with a selected column from each group coupled to a differential input of the sense amplifier, but with one of the selected columns associated with an unselected sector portion and thus serving as a dummy bit line. Conductor routing is simplified, and chip area is reduced, by maintaining unselected column groups adjacent or nearby to selected column groups.Type: GrantFiled: January 29, 2010Date of Patent: May 26, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Harvey J.

Patent number: 7706299Abstract: A technique for estimating the upstream bandwidth for a modem is provided. Various-sized packets are sent on roundtrip journeys through the modem. The roundtrip times for the various-sized packets are compared to provide an estimate of the modem's upstream bandwidth. Alternatively, a block file may be transmitted through the modem to a TFTP server. The TFTP server reports the time needed to complete the file transfer. Based upon the block file transmission start time and the completion time, an upstream bandwidth estimate may be performed. Given the upstream bandwidth estimation, non-VoIP upstream data traffic may be limited accordingly to provide a desired QoS to VoIP calls being supported by the modem.Type: GrantFiled: October 13, 2004Date of Patent: April 27, 2010Assignee: Cisco Technology, Inc.Inventors: Ray Chang, Luan Dang
