Content segmentation, categorization and identification methods are described. Content tracking approaches are illustrated that are suitable for large scale deployment. Time-aligned applications such as multi-language selection, customized advertisements, second screen services and content monitoring applications can be economically deployed at large scales. A client performs fingerprinting, scene change detection, audio turn detection, and logo detection on incoming video and gathers database search results, logos and text to identify and segment video streams into content, promos, and commercials. A learning engine is configured to learn rules for optimal identification and segmentation at each client for each channel and program. Content sensed at the client site is tracked with reduced computation and applications are executed with timing precision. A user interface for time-aligned publishing of content and subsequent usage and interaction on one or more displays is also described.

A display input device comprises a display unit having a flexibility; and a first form change detection unit having a flexibility. The first form change detection unit is able to detect a deformation ascribed to the flexibility as a change in a electrical property. A display input system further comprises a display driving unit that supplies a display signal to the display unit and signal judging unit that judges a input data based on the change in a electrical property in the first form change detection unit. The input of a first data can be performed by adding the deformation to the display input device.

Video is processed by maintaining a background model for the video, detecting a target in the video, detecting if the target is a stationary target, and classifying the stationary target as an insertion in the background model or a removal from the background model.

A vehicle brake device is provided with a hydraulic brake device for boosting by a booster device a braking manipulation force generated upon a braking manipulation, for applying a base fluid pressure generated in dependence on the boosted brake manipulation force, to wheel cylinders of wheels so that a base hydraulic brake force is generated on the wheels, and for driving a pump to generate and apply a controlled fluid pressure to the wheel cylinders so that a controlled hydraulic brake force is generated on the wheels; braking manipulation state detecting means for detecting the braking manipulation state; a regenerative brake device for causing an electric motor to generate a regenerative brake force corresponding to the braking manipulation state on the wheels driven by the electric motor; variation detecting means for detecting the variation of an actual regenerative brake force actually generated by the regeneration braking device; and brake force compensating means for generating the controlled fluid pressure by driving the pump of the hydraulic brake device so that a controlled hydraulic brake force is generated on the wheels to compensate for the lack of the regenerative brake force due to the variation which is detected by the variation detecting means.

The invention disclosed provides a driver monitoring and scoring system that detects and alerts the driver of erratic movements in order to redirect the attention of the driver so the driver can correct the poor driving. The system has the capability to record the instances of driving behavior and report them either immediately via a wireless network or from stored memory. The invention also displays a scoring system where the driver loses points for erratic driving and gains points for problem free driving. The system can maintain a list of high scores sorted by driver such that the driver can strive for higher scores resulting in better driving habits. The system can be used in the vehicle of the general public or in specific cases such as monitoring of drunk driving repeat offenders or in commercial vehicles such as school buses and public transportation.

An angular velocity detector includes a disk-shaped inertial mass supported on a substrate via driving beams and a second mass connected to the inertial mass via detecting beams. The inertial mass is oscillated in its rotational direction around a center axis (z) by an electrostatic force. When an angular velocity around a detection axis (x), which is perpendicular to the center axis (z), is imposed on the second mass while the inertial mass is oscillating, the second mass displaces in the direction parallel to the center axis (z). A capacitance between the second mass and the substrate changes according to the displacement of the second mass. The angular velocity is detected based on the changes in the capacitance. Since the driving beams allow the inertial mass to oscillate only in the rotational direction, the driving beams can be easily designed and manufactured.

Change detection apparatus for detection of changes between first and second stereoscopic image pairs obtained at different times of a substantially similar view, comprises: a two-dimensional image filter for comparing first and second image pairs to obtain an initial list of change candidates from two-dimensional information in the image pairs, and a three-dimensional image filter for comparing the image pairs at locations of the change candidates using three-dimensional image information. The apparatus retains those change candidates correlating with three-dimensional image change and rejects change candidates not correlating with three-dimensional image change, and produces a refined list of change candidates.

Method and system for combining a 2D image with a 3D point cloud for improved visualization of a common scene as well as interpretation of the success of the registration process. The resulting fused data contains the combined information from the original 3D point cloud and the information from the 2D image. The original 3D point cloud data is color coded in accordance with a color map tagging process. By fusing data from different sensors, the resulting scene has several useful attributes relating to battle space awareness, target identification, change detection within a rendered scene, and determination of registration success.

An apparatus adapted to operate as an A party in a data-base synchronization with a B party via a mobile communication network. The database contains data items to be synchronized. The apparatus includes mechanisms for maintaining a copy of the database and a client-server communication module with a client part and a server part. The client part is configured to communicate via the mobile communication network with the server part of the B party. The apparatus also includes change detection mechanisms responsive to a detection of a changed data item, for initiating a synchronization event via the client part of the client-server communication module.

This invention relates to methods of abrupt scene change detection and fade detection for indexing of MPEG-2 and MPEG-4 compressed video sequences. Abrupt scene change and fade-detection techniques applied to signals in compressed form have reasonable accuracy and the advantage of high simplicity since they are based on entropy decoding and do not require computationally expensive inverse Discrete Cosine Transformation (DCT).
