摘要:
Briefly, embodiments of the present invention describe an inexpensive, accurate, rapid and automated method to analyze for damage, defects, pitting, material changes, fracture, warpage, chips or contamination in a metal or ceramic turbine blade, pump blade, saw blade, saw tooth, gear tooth or cutting tool. This method utilizes vector signal analysis [also known as a phase-gain meter or automatic network analysis] to observe the phase and amplitude change in the transmitted energy versus the reflected energy in radio waves to detect damage, defects, pitting, material changes, fracture, warpage, chips or contamination in a metal or ceramic turbine blade, pump blade, saw blade, saw tooth, gear tooth or cutting tool. This method describes the means by which to develop specific circuits for the intended application. This method also describes the method by which to develop and tune a specific sensor/circuit for an exact application. This method also describes the type of sensor that would be used with the described method of detection. This method describes the method to obtain the signature of each tooth or blade in a rotating system. This method also describes the application of a sensor employing this method that includes: turbines, turbochargers, saws, pumps, geared equipment or cutting tools.

The invention relates to a method for damping vibrations on chassis bearings of motor vehicles, and a device for implementing the process. A process and a device are to be presented with which outstanding vibration damping and vibration isolation and noise insulation can be achieved over a wide frequency range with consideration of the driving states and roadway conditions which occur in motor vehicles. For this purpose it is proposed that the driving state of the motor vehicle and/or the roadway conditions are detected by way of sensors and that the at least one chassis bearing is modified to different characteristics to change its stiffness and/or damping depending on the detected parameters. The device is formed with sensors for detecting the driving state of the motor vehicle and for roadway conditions, with an electronic control device for processing the acquired signals and for selection of various controllable characteristics and at least one chassis bearing, the stiffness and/or damping of which can be modified.

A new behavior in a graphical user interface allows the user to open and close enclosures, while dragging an object. When the user pauses, gestures, or rolls over a hot spot on top of an icon or text representing a closed enclosure, a temporary window for the closed enclosure is “sprung open” to allow the user to browse inside the enclosure and possible open another enclosure contained within the temporary window. This process can be carried on throughout a hierarchy of windows as the user browses for a destination window for the drag operation. All of the temporary windows except the destination are closed when the mouse button is released, signaling the end of a drag. The user may close sprung open windows by simply moving the cursor out of the sprung open window, or by making some other gesture. If an enclosure to be sprung open was previously open on the desktop, the previously opened window may zoom over to the current mouse position, and then return to its original position when the user mouse is out of the window.

Methods of presenting and providing content to a user are disclosed. For example, a user may provide an input seed such as a song name or artist name. The input seed is compared to database items and a playlist is generated as a result. The playlist has an identifier corresponding to one of the database items. A first graphic element associated with the input seed is displayed. A second graphic element associated with the identifier is displayed. As another example, a plurality of database items are compared and a playlist is generated as a result. The playlist has a first identifier corresponding to a first database item. A first graphic element associated with the first identifier is displayed. A first content object corresponding to the first identifier is provided to the user.

An inbred corn line, designated 2JK221, is disclosed. The invention relates to the seeds of inbred corn line 2JK221, to the plants of inbred corn line 2JK221 and to methods for producing a corn plant, either inbred or hybrid, by crossing the inbred line 2JK221 with itself or another corn line. The invention further relates to methods for producing a corn plant of the inbred line 2JK221 containing in its genetic material one or more transgenes and to the transgenic plants produced by that method.

The invention relates to a method for filling a fuel tank (2) with a filling conduit (4). The fuel flow entering the tank is directed by a through flow sensor (53) in order to control and monitor the filling process. A particularly suitable tank system (1) for implementation of said method comprises a fuel tank (2), a filling tube (3) surrounding a filling conduit (4) and discharging into said fuel tank, an adsorption filler (6) connected to the gas area (8) of the tank (2) and a through-flow sensor (53) which detects the flow of fuel in the filling tube (2).
摘要:
An elastomeric bush bearing, with hydraulic damping, comprises a metallic inner part (1), an elastomeric bearing element (2) encompassing the inner part (1) with a cage (3) for reinforcing the bearing element (2) vulcanized thereto. At least two chambers (5), for accommodating a fluid damping medium, are separated from one another by partitions (8), constructed between the bearing element (2), adhesively bonded to the inner part (1) by the vulcanization, but are mutually connected by a damping medium channel (7). A prestressing is applied to the elastomer of the bearing element (2). However, the prestressing is not applied over the bearing shell (4), but instead over the cage (3). Calibration takes places thus by a pressure force exerted on the cage, before assembly of the bearing element (2) in the outer shell (4), which is a deviation from the state of the art.

Systems and methods of generating and modifying a playlist using contextual information are disclosed. For example, a user may provide an input seed such as a song name or artist name. The input seed is compared to database items and a playlist is generated as a result. In some examples, the contextual information is used to enhance the comparison and to select better content objects for a user's playlist. Meanwhile, in some examples the content objects in the playlist may be arranged in an enhanced order using ranking and/or contextual information.
