Abstract: Aspects of the present invention include systems and methods for generating an optical flow-based feature. In embodiments, to extract an optical flow feature, the optical flow at sparse interest points is obtained, and Locality-constrained Linear Coding (LLC) is applied to the sparse interest points to embed each flow into a higher-dimensional code. In embodiments, for an image frame, the multiple codes are combined together using a weighted pooling that is related to the distribution of the optical flows in the image frame. In embodiments, the feature may be used in training models to detect actions, in trained models for action detection, or both.

Abstract: Systems and methods are disclosed for classifying an input image by detecting one or more feature points on the input image; extracting one or more descriptors from each feature point; applying a codebook to quantize each descriptor and generate code from each descriptor; applying spatial pyramid matching to generate histograms; and concatenating histograms from all sub-regions to generate a final representation of the image for classification.

Abstract: Systems and methods are disclosed to perform image parsing on one or more images by identifying a set of similar regions from each image; assigning one or more region labels to each region and generating multiple hypotheses for region label assignment; and detecting class, location and boundary of each object in the image, wherein object classification, detection and segmentation are performed jointly during image parsing.

Abstract: A computer-implemented method and system for predicting operation risks of a vehicle. The method and system obtains a training data stream of vehicular dynamic parameters and logging crash time instances; partitions the data stream into units representing dimension vectors, labels the units that overlap the crash time instances as most dangerous; labels the units, which are furthest from the units that are labeled as most dangerous, as most safe; propagates the most dangerous and the most safe labeling information of the labeled units to units which are not labeled; estimates parameters of a danger-level function using the labeled and unlabeled units; and applies the danger-level function to an actual data stream of vehicular dynamic parameters to predict the operation risks of the vehicle.

Abstract: Systems and methods are disclosed to predict driving danger by capturing vehicle dynamic parameter, driver physiological data and driver behavior feature; applying a learning algorithm to the features; and predicting driving danger.

Abstract: Systems and methods are disclosed for generating super resolution images by building a set of multi-resolution bases from one or more training images; estimating a sparse resolution-invariant representation of an image, and reconstructing one or more missing patches at any resolution level.

Abstract: An earpiece for communications comprises a frame, a vibration system disposed in the frame and a magnetic field system disposed in the frame. The vibration system includes a vibrating armature, a diaphragm and a connecting rod. The magnetic field system includes a magnet to generate a first magnetic field on a first axis and a coil to generate a second magnetic field on a second axis. One of the magnet and the coil is connected to the frame. The first and the second magnetic fields produce a net magnetic force to cause the vibration system to move. The first axis is parallel to the second axis.

Abstract: A replacement wheel, wheel disc or object is adapted to substantially replicate a mounting pad pattern of a wheel, wheel disc or object to be replaced. An annular arrangement of raised mounting pads provides a pattern of mounting pads proximate a circle of a given diameter to substantially replicate the mounting pad pattern of the to-be-replaced wheel disc or objects Mounting pads may be provided on an annular member having an inner diameter less than the given diameter of a circle at which the mounting pad pattern of the to-be-replaced wheel disc or object is located and having an outer diameter greater than the given diameter. Mounting pads may be provided by inserts.

Abstract: A vehicle wheel assembly includes a rim secured to a hub of a wheel, a tire secured to the rim, and a hollow stud. The hollow stud includes an air passageway and extends through a rim opening that one end secured to the hub. A lug nut is secured to the hollow stud at its other end. The one end is operably connected to a source of compressed air through the air passageway. A central tire inflation valve is secured to the rim. The rim includes a first internal passageway communicating with the air passageway and the valve, and a second internal passageway communicating with the valve and the interior of the tire.

Abstract: A multi-part automotive wheel comprises first and second wheel discs having first and second mating surfaces, respectively, where the first and second discs are to be joined to each other. An annular radial groove is disposed on one of the first and second surfaces for receiving an O-ring for sealing the first surface in respect of the second surface. The groove includes a substantially radial basewall and first and second sidewalls which extend from the basewall toward an intermediate section and from the section toward both edges of the groove, the edges defining a radial groove opening which is smaller than a distance between the sidewalls at the section such that an O-ring having a larger cross-sectional diameter larger than the opening will be retained within the groove prior to the discs being joined together. The basewall merges with the first and second sidewalls with rounded corners to reduce concentration of stress at the corners.
