Abstract

An elastic transformer serving system, referred to herein as an online token adaptation system (OTAS), is described that accommodates diverse user requests with fluctuating query louds while optimizing output accuracy and runtime latency. The OTAS uses a token adaptation technique that involves adding prompting tokens to improve accuracy and removing redundant tokens to accelerate inference. To cope with fluctuating query loads and diverse user requests, the OTAS further uses application-aware selective batching in combination with online token adaptation. In an example embodiment, the OTAS first batches incoming queries with similar service-level objects to improve the ingress throughput. Then, to strike a trade-off between the overhead of token increment and the potential for accuracy improvement, the OTAS adaptively adjusts the token execution settings by solving an optimization problem.

Abstract

Three-dimensional (3D) hierarchical morphologies widely exist in natural and biomimetic materials, which impart preferential functions including liquid and mass transport, energy conversion, and signal transmission for various applications. While notable progress has been made in the design and manufacturing of various hierarchical materials, the state-of-the-art approaches suffer from limited materials selection, high costs, as well as low processing throughput. Herein, by harnessing the configurable elastic crack engineering-controlled formation and configuration of cracks in elastic materials, an effect normally avoided in various industrial processes, the present invention provides a facile and powerful technique to enable the faithful transfer of arbitrary hierarchical structures with broad material compatibility and structural and functional integrity. The present invention provides a cost-effective, large-scale production method of a variety of flexible, inexpensive, and transparent 3D hierarchical and biomimetic materials.

Abstract

Techniques for using ferroelectric liquid crystals Dammann grating (FLCDG) for light detection and ranging devices are disclosed. In LiDAR devices, accuracy, response time, and cost performance can be limited by some factors, such as laser pulse width, time resolution of a time-to-digital conversion chip, detector bandwidth, shot noise, and time error generated by electronic circuits. A FLCDG-based architecture can improve a LiDAR device, and provide for one-shot capturing due to the high switching speed at very low driving voltage provided by ferroelectric liquid crystals and the equal diffracting ability of Dammann grating.

Abstract

Techniques for designing and optimization of solid/cellular structures are described using a modeling process referred to as high-definition cellular level set in B-splines (HD-CLIBS). With this process, the entire design domain for the solid/cellular structure in question is subdivided into a set of connected volumetric cells in three dimensions. An implicit trivariate B-spline function is defined on each subdomain cell. With this parameterization scheme, constraints can be imposed on the relevant B-spline coefficients to naturally maintain geometric continuities at the connection faces between neighboring cells. The method offers several useful properties and powerful functionalities to build and modify a solid/cellular structure in the modeling process and to conduct topology optimization by directly adjusting the B-spline coefficients. The model construction can be carried out using a fast B-spline interpolation, and the topology optimization can involve a sequence of discrete B-spline convolutions.

Abstract

Techniques for fingertip design are disclosed that leverage how most grasp contacts can share a few classes of local geometries. In order to maximize the contact areas for achieving more robust grasps, contact primitives, which represent a set of contacts of similar local geometries, are identified. A uniform cost algorithm, which can be formulated as a decision making process in a tree structure, can be utilized to cluster a set of example grasp contacts into a finite set of one or more contact primitives. Fingertips can be designed by optimization to match the local geometry of each contact primitive, and then fingertips can be 3D printed using soft materials to compensate for optimization residuals. For novel objects, an approach to generate grasp contacts that match the fingertip geometries while together forming stable grasps can be utilized.

Using subset sampling, the system detect the altered access points, filter them out by a received signal strength vector and find the location of a client. Given the received signal strength vectors received and the estimated location, the system can update a fingerprint database with the signal changes by applying a non-parametric Gaussian process regression method.

Abstract

Locating mobile devices based on a junction of signal tiles is disclosed herein. Mobile devices are mapped to a convex hull within which the mobile device is likely to be located in based on a received signal strength indicator (RSSI) associated with an access point (AP). Using the RSSI from a set of APs, the mobile device can be located within a junction of a set of convex hulls, or tiles using a linear programming function. To mitigate signal noise and improve the accuracy of the location determination, the localization system can use the RSSIs of the APs that have signals with a predetermined signal dynamic range that leads to smaller tiles. Additionally, the localization system can reduce the search complexity of matching fingerprints to APs by partitioning the space into clusters with reference points that have similar signal vectors.

A weighted sum of a first data rate for a first linear transceiver matrix and a second data rate of a second linear transceiver matrix is maximized based on the channel matrices, the first streams, and the second streams. The base station generates a first linear transceiver vector used in transmission of the first streams to the base station from the uplink user devices and a second linear transceiver vector used in transmission of the second streams from the base station to the downlink user devices.

Abstract

Stream-switching techniques are applied in a content delivery system. A merge frame is generated as a function of bit-rates, distortion, and a piecewise constant operator. Parameters of the piecewise constant operator are selected to optimize the merge frame. Data streams are switched based on bandwidth requirements, switch requests, and throughput of a network. Images are reconstructed based on the merge frames and prediction frames. Reconstructed images are identically reconstructed for any prediction frame based on the merge frame.

Abstract

Described herein are systems and methods that employ a widgetless and buttonless multi-touch interface for constrained manipulations of 3D objects. The widget-less multi-touch user interface can map different multi-touch gestures to different 3D object manipulation tasks, allowing a user to manipulate 3D objects without operating widgets or performing mode switchings or tool selections. User interaction is greatly simplified by using single touch actions that simultaneously specify the transformation constraint, the transformation type, and the magnitude of transformation and apply the transformation to the focus object. Additionally, the axis-based constrained manipulations support active snapping and axis transfer. Active snapping allows the user to draw a free touch path connecting two 3D objects to be snapped together, avoiding tedious operations required with standard transformation manipulations. Axis transfer provides a simple solution to achieve relative transformations between objects, allowing an object to be transformed along a specific predefined axis of another object.
