Abstract: Node-link data can be converted into audio outputs. For example, a system can generate a graphical user interface (GUI) depicting a node-link diagram having nodes and links. The GUI can include a virtual reference point in the node-link diagram and a virtual control element that is rotatable around the virtual reference point by a user to contact one or more of the nodes in the node-link diagram. The system can receive user input for rotating the virtual control element around the virtual reference point, which can generate a contact between the virtual control element and a particular node of the node-link diagram. In response to detecting the contact, the system can determine a sound characteristic configured to indicate an attribute associated with the particular node. The system can then generate a sound having the sound characteristic, for example to assist the user in exploring the node-link diagram.

Abstract: Geospatial data can be converted into audio outputs. For example, a system can receive a dataset indicating geospatial locations of objects within a region. Based on the dataset, the system can generate a virtual map representing the region and including virtual points representing the objects. The virtual points can be spatially positioned at locations in the virtual map corresponding to the geospatial locations of the objects in the region. The system can receive a user input via a user input device for interacting with a particular virtual point among the virtual points in the virtual map. The system can determine one or more sound characteristics for a sound based on receiving the user input. The system can then transmit an audio signal to an audio device for causing the audio device to generate the sound having the one or more sound characteristics, which may assist with exploring the virtual map.

Abstract: Graphical data-visualizations can be converted into sonified output. For example, a computing device can detect metadata that describes data points for a graphical visualization. The computing device can generate an interactive interface that is different from the graphical visualization based on the metadata. The interactive interface may include a matrix of cells corresponding to the data points in the metadata. The computing device can detect an interaction with a cell in the matrix. The interaction can indicate that a sonified representation of a data point corresponding to the cell is to be output. The computing device can responsively determine at least two sound characteristics for the sonified representation of the data point using a portion of the metadata describing the data point. The at least two sound characteristics can each audibly represent different aspects of the data point. The computing device can then cause the sonified representation to be output.

Abstract: Disclosed herein is a new improved large planetary gear system used on the input stage of wind turbine power generators. This improved planetary gear system reduces or eliminates lubricant debris traditionally generated from the gear teeth, thereby eliminating an initiating source for bearing failure. To achieve these results, some and preferably all of the gear teeth within the planetary gear system are superfinished using chemically accelerated vibratory finishing to a surface roughness of approximately 0.25 micron or less. Several objects and advantages of the invention are to provide a gearbox with reduced metal debris, improved bearing life, reduced wear, reduced vibro-frictional noise, improved contact fatigue, improved fretting resistance, improved lubrication, to simplify the run-in process, and to enhance the durability and efficiency of the gearbox.

The stiff fibres or filaments may be heavy monofilaments, for example of nylon, polyester or unplasticized polypropylene of from 30 to 300 tex, or they may be of metallic material. Alternatively, the stiff fibres can be in the form of twisted yarn which has been resinated to stiffen it.Processes for making the carpeting material are also described and claimed.

Abstract: An electronic flash unit for use with cameras having a flash lamp firing mechanism adapted to fire flash lamps in timed relation with the operation of a camera shutter. An electronic time delay circuit coupled to the flash lamp firing mechanism energizes a flash unit trigger circuit to fire the flashtube in synchronism with the camera shutter. A voltage-sensitive switching element renders the delay circuit operative once the flash unit firing capacitor is charged above a predetermined level. With this arrangement, the flash-firing mechanism cannot energize the flashtube trigger circuit when there is insufficient firing capacitor voltage.
