摘要:
This invention relates to a shock and impact testing apparatus for subjecting items under test, such as a motor vehicle crash sensor, to an acceleration pulse of a prescribed amplitude and shape, such as a half sine or haversine. The apparatus includes a stationary support providing a pivot point, a swivel arm mounted for rotational movement about the pivot point and an electric motor, arranged on the stationary support and mechanically coupled to the swivel arm, for rotating the swivel arm at a desired, prescribed speed. The arm has a free end for the attachment of the test object so that the test object is moved at the prescribed speed along a given path. A mechanical spring is arranged in this path for reversing the direction of motion of the test object, thereby imparting an acceleration pulse to the test object of a prescribed shape. The spring has a plurality of characteristic modes of vibration which provide different frequencies of vibration; however, the spring is constructed to reverse the direction of motion of the test object at substantially one frequency of vibration. The apparatus can also be used for subjecting a test object to a prescribed impact.

An optical scanner has grease bearings between the rotor and the housing. The grease bearings are grooved which tends to pump the grease back into the bearing cups when the optical scanner is operating. The thixotropic property of the grease prevents its escape from the bearing cups when the optical scanner is not operating. The grease bearings can be frusto-conical or spherical in shape with complementary shaped bearing cups. The bearing cups, rather than the bearings, may be grooved. The bearing cups may also be stepped to provide a pumping region and a reservoir region for the grease. Pressure means within the scanner housing may force the bearing cups onto the grease bearing.

A method of rendering an electronic graphical representation of a user of a computerized system includes providing a plurality of states for the electronic graphical representation including first and second differing states, monitoring a measurable quantity to provide a monitored quantity, and changing a state of the graphical representation from the first state to the second state based upon the monitored quantity. The graphical representation is an avatar and the method includes defining a receptor point associated with the avatar and associating an object with the receptor point. The receptor point is located on the avatar. The plurality of states includes a non-hybrid state. The plurality of states includes a hybrid state. The hybrid state is a static image hybrid state and a video hybrid state. The video hybrid state is a live video hybrid state and a pre-recorded video hybrid state.

Methods, including service methods, articles of manufacture, systems, articles and programmable devices are provided for adapting the power consumption of a computational device in response to environmental conditions. Operating environmental condition data relevant to the generation of electric power is acquired from an operating environment feed and analyzed to determine a high electric power demand indication. If the analyzing determines a high electric power demand indication, then a computational device automatically reduces an amount of electric power consumption.

Arrangements and methods for performing structural clustering between different time series. Time series data relating to a plurality of time series is accepted, structural features relating to the time series data are ascertained, and at least one distance between different time series via employing the structural features is determined. The different time series may be partitioned into clusters based on the at least one distance, and/or the k closest matches to a given time series query based on the at least one distance may be returned.

A system, a method and a computer readable media for replicating virtual universe objects are provided. In one exemplary embodiment, the method includes determining a first set of VU objects associated with a first user. The method further includes determining replication priority values for the first set of VU objects utilizing predetermined priority value rules. Each VU object of the first set of VU objects has a replication priority value. The method further includes determining a second set of VU objects from the first set of VU objects based on the replication priority values associated with the first set of VU objects. The method further includes replicating the second set of VU objects from a primary VU computer server to a first device.
