Medical devices having one or more rotatable linkable components or segments, delivered in a first orientation relative to a component guide into a tissue cavity, such as the interbody vertebral space. After delivery, each segment may be rotated to a second, different orientation relative to the component guide, such as into a permanent vertical standing position. The segments achieve maximum distraction of the cavity space such as adjacent vertebra end plates, while using a minimal invasive surgical (MIS) approach. When the segments are tightened in place, the device provides long-term stability. The device can be used as a distraction instrument and/or permanent implant that can be used for interbody fusion, nuclear replacement, or anywhere in the body where a stable distraction of tissue and/or the implantation of material such as a device with an MIS approach is desired.

A liquid crystal display device includes a display section, an image signal drive circuit, a scan signal drive circuit, a common electrode potential control circuit, and a synchronous circuit. The display section has scan electrodes, image signal electrodes, a plurality of pixel electrodes arranged in a matrix, a plurality of switching elements for transmitting an image signal to the pixel electrodes, and a common electrode. The common electrode potential control circuit changes an electric potential of the common electrode into a pulse shape, after the scan signal drive circuit has scanned all the scan electrodes and the image signal has been transmitted to the pixel electrodes. Otherwise, the image signal is overdriven. Otherwise, torque for returning to a no-voltage-application state is increased.

The invention provides a method and system for operating a solar farm inverter as a Flexible AC Transmission System (FACTS) device—a STATCOM—for voltage control. The solar farm inverter can provide voltage regulation, damping enhancement, stability improvement and other benefits provided by FACTS devices. In one embodiment, the solar farm operating as a STATCOM at night is employed to increase the connectivity of neighbouring wind farms that produce peak power at night due to high winds, but are unable to connect due to voltage regulation issues. The present invention can also operate during the day because there remains inverter capacity after real power export by the solar farm. Additional auxiliary controllers are incorporated in the solar farm inverter to enhance damping and stability, and provide other benefits provided by FACTS devices.

The exercise device has an elongate flexible member connected to a base. The flexible member has an upper surface and a lower surface. The upper surface has a pair of foot placement portions configured and arranged such that a user positioned thereon must exercise balance. The foot placement portions are separated along the longitudinal axis such that a user standing thereon assumes an athletic stance.

A keyboard mechanism for a low-travel keyboard and methods of fabrication are described. The low-travel keyboard is suitable for a thin-profile computing device, such as a laptop computer, netbook computer, desktop computer, etc. The keyboard includes a key cap that can be formed of a variety of materials in the form of a flat slab. The key cap is attached to one end of a support lever that supports it from underneath. In one embodiment, the support lever is formed of a rigid material and is pivotally coupled with a substrate on the other end. In another embodiment, the support lever is formed of a flexible material and is fixedly attached to the substrate on the other end. The portion of the support lever that is attached to the key cap is positioned over a metal dome that can be deformed to activate the switch circuitry of the membrane on printed circuit board underneath the dome.

The presence of radiation shielding material concealing illegitimate content in a container is detected by obtaining each of measured gamma-ray data and measured neutron data from the container, and comparing the measured gamma-ray and neutron data to expected gamma-ray and neutron data. An anomaly between the measured data and the expected data is an indicum of the presence of such material shielding such illegitimate content.

Extrusion of a mix containing a pharmaceutically active agent can be achieved using a plasticising excipient in an amount sufficient to act as plasticiser and also act as lubricant, thereby avoiding the need for inclusion of a lubricant. The invention provides multiparticulates with controlled release properties, substantially free of lubricant. The present invention is preferably directed to extruded multiparticulates containing an opioid such as oxycodone, an ammonium methacrylate copolymer such as Eudragit® RSPO, a plasticising excipient such as preferably stearyl alcohol and a water permeability modifier such as preferably Eudragit® RLPO. The obtained multiparticulates show a release rate profile which is pH-independent.

Pulsating light is used to penetrate a user's finger placed an input surface (which can be a fiber optic surface) of a video camera to avoid the effects of bloodflow from a normal human pulse on the quality of the image which would otherwise change the contrast of the image. The use of pulsating light of shorter durations than a typical human pulse provides an accurate image of a portion of a finger for identification. A retractable cover blocks the fiber optic input surface during a non-working mode, and allows access for identification during a working mode. A light source having a plurality of light emitting diodes provides light that diaphans a portion of the finger. Several successive frames of image signals allow for biometric detection and verification of a human pulse to ensure the finger is not a counterfeit.

The invention discloses a method for identifying abnormal motion in a video. The method comprises the steps that an area of which the pixels have certain change is extracted from a video sequence through a foreground extraction module; a movement target detected by the foreground extraction module is judged through a pedestrian judgment module, and a rectangular box judged to be a pedestrian is kept and transmitted to a target tracking module; each identified target in the scene is continuously tracked in a multi-target way through the target tracking module; the posture of each target tracked by the target tracking module within each frame of time is judged through an abnormal behavior trigger module and behavior analysis is performed on the abnormal behavior; and the abnormal behavior is processed and computed into a video segment through a behavior identification module, and the abnormal behavior is alarmed and the behavior type of the abnormal behavior is identified. The invention also discloses a system for identifying the abnormal motion in the video. The problem that abnormal behavior (falling down) detection of massive video data cannot be performed in real time can be solved and the detection accuracy can be greatly enhanced.

A user-mode device driver architecture is provided by the subject invention. The architecture includes a reflector, a driver manager and a host process which hosts and isolates one or more user-mode device driver(s). The user-mode device driver runs in the user-mode (UM) environment and has access to various UM services. The reflector resides in “kernel memory” (e.g., memory/resource(s) available to operating system) while the driver manager, host process and user mode device driver(s) are located in user space (e.g., memory/resource(s) available to user application(s)). The reflector provides a secure, stable communication path for application(s), the host process and/or user-mode device driver(s) to communicate with the operating system. The reflector can redirect input/output (I/O) request(s) from application(s) to the user-mode device driver(s) via the host process. The driver manager can create the host process (e.g., in response to a request from the reflector), track information about the host process and/or destroy the host process (e.g., in response to a request from the reflector).
