Abstract: A 3D building model generator has a server that constructs a 3D texture model for each floor in a building by extruding a 2D floor plan to 3D using user-inputted heights, and adding photos captured by a smartphone or mobile device as textures to image planes for surfaces in the 3D model. The server displays on the smartphone a floor-plan portion, or a virtual 3D display based on the camera orientation with a facing wall highlighted and confirmed by a smartphone user. The user moves mapping points overlaid upon the photo to wall corners to map the photo to the facing surface in the model. The user flags rooms and exits such as doors and elevators as walkable. The server stacks the 3D texture model for the floors and connects them into a walkable network of the rooms and exits that are flagged as walkable. Hashing removes duplicate floorplans.

Abstract: Systems and methods for motion tracking on a hardware device without a camera and/or without a sufficiently powerful hardware processor, by offloading pose processing fully or partially to a mobile device, are disclosed. Methods executable on the hardware device include receiving pose data associated with a user from the mobile device, and performing a touchless control of an application on the hardware device, based on the received pose data. Methods executable on the mobile device include capturing at least one image associated with a user, performing a pose recognition algorithm on the mobile device, based on the captured image, to generate pose data for performing a touchless control of an application on the hardware device, and transmitting the pose data to the hardware device, using the network connection. The methods and systems include embodiments where the pose recognition algorithm uses machine learning.

Abstract: Systems and methods which provide for auditable data are described. Data management systems of embodiments facilitate storage and management of various data (e.g., information regarding transactions, customers, infrastructure, geographic locations, medical records, etc.) for supporting data creation, manipulation, storing, and/or sharing by and among different parties. Users may create new and/or update data, digitally sign the data, and store the digital signature and data on immutable storage using data structures of a data management system. A data structure in which data and associated metadata is stored on immutable storage in association with a digital signature corresponding to the data and user may be used in providing data traceability and auditability. Snapshots of merged data may be implemented with respect to data having many updates to avoid delays in merging update data for queries for that data. A collaborative rating mechanism may provide trust levels with respect to the data.

Abstract: Methods, systems, and devices supporting mapping user interface (UI) states for a web document are described. A UI state mapper program may determine a set of interactable elements that are configured to cause a UI state change to a UI of the web document, such as from a configuration for the web document. The UI state mapper program may interact with the set of interactable elements of the UI. The UI state mapper program may generate sets of nodes in a graphical node representation in response to the interacting. The sets of nodes may include nodes of a first node type with a UI state change resulting from a universal resource locator (URL) change and nodes of a second node type with a UI state change resulting from a visual effect on the UI without a URL change. The UI state mapper may generate a computer readable record indicating a sequence of interactions by the UI state mapper program to generate the graphical node representation.

Abstract: Methods and systems for touchless control of a device include receiving at least one image; determining a first map, the first map including a function that generates a correspondence between data associated with the image to a feature space; determining a second map including a representation of a user in the image based on the first map; determining a third map comprising a field associated with the data in the image; determining a characteristic of the user based on one or more of the second map and the third map; and tracking the characteristic of the user to generate a historical data of the characteristic for performing the touchless control of the device.

Abstract: Methods and systems for touchless control of a device include receiving an image from a camera and applying a machine learning technique the image to determine a first map, the first map including a function that generates a correspondence between data associated with the image to a feature space. A second map including a representation of a user in the image can be determined based on the first map. Further, a pose of the user can be determined based on the second map. The pose of the user and a portion of a body of the user can be tracked to determine a mapping between the portion of the user's body and an input feature of a device. The input feature can be modified based on the mapping to enable a touchless interaction between the user and the device.

Abstract: A phase-locked loop (PLL) includes a phase-frequency detector that compares a reference signal to a feedback signal. The difference in phase between the reference signal and the feedback signal is encoded as digital pulses on one or more outputs of the phase-frequency detector. The digital output pulses from the phase-frequency detector are duplicated and delayed multiple times in a non-overlapping manner before being input to the loop filter or voltage controlled oscillator (VCO) of the PLL.
