Abstract: A panel structure having a low-density core that can withstanding loads normal to a first primary surface, and a first facing of high-density sheet material that can extend along the first primary surface. The high-density sheet material can be laminated on the core such that the laminated core and facing cooperatively resist bending loads and loads along the primary surface. The first facing can extend from the first primary surface on a side of the core along a secondary surface, which can be non-parallel to the first primary surface. The first facing can bend along a score line between the first primary surface and the secondary surface.

Abstract: A system and method are disclosed for detecting and correcting data errors. The system analyzes a transmitted data stream and generates a transmitted primary code from the transmitted data stream. The transmitted primary code may be sent in association with the transmitted data stream. The system further analyzes the data stream as received and generates a received primary code from the received data stream. Comparison of the transmitted and received primary codes may be used to detect and correct one bit and generally multiple bit data errors in the received data stream.

Abstract: A method of securing a prosthetic device to tissue includes providing an applicator instrument including a housing, a shaft, surgical fasteners, a firing rod for dispensing the surgical fasteners from the shaft, a trigger, and an energy storing element. The method includes positioning a prosthetic device over tissue, juxtaposing a distal end of the shaft with the prosthetic device, and compressing the trigger for piloting the firing rod toward the distal end of the elongated shaft at a first rate of speed. The method includes preventing the firing rod from moving distally while building up energy in the energy storing element, and further compressing the trigger for releasing the firing rod for distal movement and transferring the built up energy for moving the firing rod toward the distal end of the elongated shaft at a second rate of speed that is greater than the first rate of speed.

Abstract: Disclosed herein is a fuel oil composition comprising a renewable fuel or a blend of petroleum based fuels with renewable fuels, also containing an additives composition to enhance the base and combined fuel's resistance to forming insoluble particulates upon storage at diminished operating temperatures. Further described is the additive package used to inhibit particulate formation.

Abstract: Imaging data regarding an interior portion of a storage vessel may be obtained from an imaging device (e.g., a digital camera or depth sensor) and interpreted in order to identify an available volume within the storage vessel. Where the imaging data includes an image of an interior of the storage vessel, an area of one or more contiguous spaces of a rear face of the storage vessel may be identified from the image and multiplied by a depth of the storage vessel in order to estimate the available volume. Where the imaging data includes a depth profile of the interior, the depth profile may be processed in order to estimate the available volume. Once an available volume has been estimated, the capacity of the available volume to accommodate one or more additional items may be determined, and information regarding the capacity may be provided to a user.

Abstract: A gate valve includes a body with a flow passage intersected by a gate cavity and a gate with an axis, the gate being axially movable in the gate cavity between a gate closed position and a gate open position. A lifting device is in engagement with a stem of the gate to move the gate to the gate open position. A port extends from a first external surface of the gate to a second external surface of the gate. A seal member is mechanically connected to the lifting device, the seal member being moveable in response to axial movement of the lifting device between a seal open position where fluids can flow through the port and a seal closed position where the seal member blocks fluids from flowing through the port.

Abstract: An exemplary martial arts training device comprises anatomically correct legs, arms, torso and head that can be used individually, or partly or fully assembled. A user interacts with the device, and receives both immediate feedback and a global analysis of his training session. Feedback can include whether proper forces and angles were applied to achieve an actual break or other desired fighting goal in an opponent, and can be measured by the actual breaking of various strike points on the device, or by alerting the user when an appropriate sensor is struck with the required strength. The device can include breakable joints, bones, as well as soft tissue targets preset to respond to a defined striking force or joint manipulation. The user can reset the damaged physical structure or response sensor to its original configuration and setting, making the device repeatedly reusable.

Abstract: Data compression is described herein. The encoder transmits a coded word having replacement bits, as well as a code that defines the starting location of the replacement bits in a data sample. The replacement bits may be actual bits from a selected location in the new data sample. The selected location of the replacement bits can vary from data sample to data sample. The encoder may select the location based on the most significant bit that has changed. Thus, reconstructed data will be bit-accurate from the replaced bits all the way to the highest-order bit. A limited number of key values can be transmitted losslessly. Moreover, the data compression does not need forward error correction (FEC), which is a necessary part of many lossy delta encoding schemes. Furthermore, the encoding and decoding can be done very efficiently in terms of hardware and/or software.

The client device processes the status information present the one or more graphical representations of the current condition of the one or more mechanical components of the vehicle on the client device.

Abstract: A coaxial stabilizing and sealing catheter provides increased support to a guide catheter that is seated in an ostium of a branch artery by extending through and out of a distal end of the guide catheter and anchoring in position within the vessel that is being treated. The stabilizing and sealing catheter includes, as part of a relatively flexible distal section, a balloon that locks the distal end of the stabilizing and sealing catheter in place to provide support to the therapeutic devices that are introduced and further seals the artery to prevent blood from entering the artery. A sealing cuff at a proximal end of the stabilizing and sealing catheter provides a seal between the exterior of the stabilizing and sealing catheter and the interior of the guide catheter. In addition, a fixing mechanism it utilized to lock the guide catheter in place to exchange therapeutic devices.

Abstract: A data transport system for transporting data and auxiliary signals over an optical link comprises a transmitter, a receiver and an optical link. The transmitter and receiver are coupled to a first end of the optical link. The optical link includes a number of optical channels. A controller is coupled to the transmitter and the receiver, and controls the transmitter and the receiver to operate in a first state when data are detected at an input of the transmitter. Data are transported via the data transport system in the first state. The controller controls the transmitter and the receiver to operate in a second state when the data are detected as absent at the input of the transmitter. Data are prevented from being transported via the data transport system in the second state.
