Systems and methods of increasing blood flow in a blood vessel with ultraluminal plaque. One disclosed method includes inserting an imaging guidewire into the blood vessel to the intraluminal plaque, propelling a catheter with a working head over the guidewire towards the distal end of the guidewire, scanning with the imaging guidewire to generate a cross-section image, radially positioning the catheter using a positioning element, monitoring the image to ascertain that the working head is properly positioned and operating the working head to remove the plaque. A computerized system designed, constructed and configured to perform the methods is further disclosed.

An embodiment relates generally to a method of operating a device. The method includes providing for a plurality of sensors, where each sensor is configured to sense and transmit data values associated with an interaction with the device by a user. A subset of the sensors of the plurality of sensors is associated with a respective facing on a housing of the device. The method also includes operating the plurality of sensors to detect the interaction with the device by the user and receiving sensor data associated with the interaction from the plurality of sensors. The method further includes determining a user mode of the device based on the sensor data associated with the interaction.

A breech system for a firearm exhibits a breech which can be locked in its movement in the barrel block by at least one locking element, which is pressed against the rear end of the barrel by means of a breech spring surrounding the rigid barrel of the weapon, the barrel being enclosed with the exception of the front and rear apertures, whereby the breech spring is supported at the rear section of the barrel and at least one link element subjected to tension connects the front end of the breech spring and the breech. In order to guarantee precise function and in a manner which is safe for the user, by means of a simple arrangement which is reproducible in manufacture, a purely mechanical delay element is inserted in the link between the breech (10) and the breech spring (9).

The invention aims at disclosing a method for managing USBKey unlocking secret keys intensively and safely. Before the USBKeys are delivered to a user for use, an exclusive unlocking secret key is generated for each USBKey, and the exclusive unlocking secret keys are ensured to be safely stored at the same time. When unlocking is required, the USBKeys can be unlocked through the unlocking secret keys. When a large amount of USBKey devices are distributed, the safety of the USBKey unlocking secret keys can be ensured, and safe unlocking is provided for locking of follow-up USBKeys in using process, thereby achieving the purpose.

A self-propelled chemical delivery vehicle and dispenser generally for agricultural use includes a frame including first and second vertically spaced support members; a rider support member mounted to the frame; an apparatus for providing motive power mounted to the frame; at least two wheel and tire assemblies, with one of the at least two wheels being a drive wheel, the drive wheel being in communication with the apparatus for providing motive power for application of motive power through the ground contact for vehicle movement with the at least two wheel and tire assemblies being spaced apart in generally longitudinal alignment; and an assembly for directional control of the self-propelled chemical delivery vehicle and dispenser mounted to the frame. Also included is a chemical reservoir mounted to the frame intermediate the first and second vertically spaced support members and intermediate the at least two wheel and tire assemblies; and a chemical delivery assembly mounted to the frame in communication with the chemical reservoir for selective, operator controlled chemical distribution therefrom. In addition, the chemical reservoir is mounted to the frame coincident with the center of gravity of the two-wheeled chemical delivery vehicle and dispenser.

An anti-skid mat including a skid-resistant material exhibiting flexible properties and having a generally planar configuration with a length, width and thickness. A plurality of hinges or flex lines design into the material and which enable the material to conform to any irregular surface associated with the metal roof. The mat underside can include any or both of magnetic attracting or conformal adhering undersides such that placement of the material upon a sloping magnetic attracting or non-attracting roof securely supports the weight of a user standing on the mat without slippage relative to the roof.

The invention discloses selenium-enriched sparassis crispa powder as well as a food preparation method and a preparation. The selenium-enriched sparassis crispa powder is prepared by taking artificially-cultured bagged or bottled sparassis crispa hyphae as raw materials through drying and grinding; the sparassis crispa hyphae are obtained by culturing hyphae, growing and coloring. The method comprises the following steps: taking out the sparassis crispa hyphae and a culture medium; freezing and drying by hot air; and grinding. In the whole process of preparing the sparassis crispa powder and a product thereof, a chemical additive does not need to be added so that the food safety is guaranteed; a traditional eating manner of sparassis crispa is changed and the nutritional ingredients of the sparassis crispa are prevented from being lost in the cooking process; the sparassis crispa is convenient and simple to eat and the eating health-care value of the sparassis crispa is improved; the sparassis crispa powder and the product are prepared by the technology provided by the invention; the raw materials are ecological, the technology is simple and convenient, and contradictions caused by the fact that the resource of current wild sparassis crispa is scarce, the price is high and almost people cannot afford can be remitted; a safe and efficient new way is provided for developing and utilizing the sparassis crispa into a dietary supplementing agent.
