20090025948 | Percussion Device - The invention relates to a method for controlling the operation of a pressure fluid operated percussion device and to a pressure fluid operated percussion device. The method comprises influencing the shape of a stress wave by setting a suitable clearance between a transmission piston and a tool. The percussion device is provided with means for setting the clearance between the transmission piston and the tool. | 01-29-2009 |
20090065256 | Method and Rock Drilling Rig for Hole Drilling - The invention relates to a method and a rock drilling rig for drilling a hole in a rock. In the method the hole is drilled with a so-called top-hammer rock drilling rig including a drill rod and a cone roller bit at the end of the drill rod. During drilling with the percussion device, stress pulses of low amplitude are produced at a high frequency of at least 200 Hz. In the rock drilling rig, the cone roller bit ( | 03-12-2009 |
20090188686 | Method for controlling percussion device, software production, and percussion device - A method and software product for controlling a percussion device belonging to a rock-drilling machine, and a percussion device. The impact frequency of the percussion device is set so that the percussion device forms a new compression stress wave to the tool always when reflected waves from the previous compression stress waves reach a first end of the tool. This requires that the impact frequency be set proportional to the propagation time of the stress wave, whereby the length of the used tool and the propagation velocity of the stress wave in the tool material are to be noted. | 07-30-2009 |
20090266568 | Method for Controlling Pressure Fluid Operated Percussion Device, and Percussion Device - The invention relates to a method for controlling a pressure fluid operated percussion device comprising a working chamber for pressure fluid and in the working chamber a transmission piston installed movably with respect thereto so as to enable a tool installed in the percussion device to be pressed against a material to be broken in order to generate a stress pulse, and to a percussion device. | 10-29-2009 |

20090271847 | Methods, Apparatuses, and Computer Program Products for Providing a Single Service Sign-On - An apparatus may include a processor configured to receive a request for an access token from a remote entity, wherein the request includes an indication of a requested service. The processor may be further configured to determine a request type, wherein the request type may be a user identification and password combination, a request token exchange, or an access token exchange. The processor may be additionally configured to extract one or more parameters included in the request based upon the determined request type and to perform one or more security checks based at least in part upon the one or more extracted parameters. The processor may be further configured to create an access token based at least in part upon the results of the one or more security checks and to provide the access token to the remote entity. | 10-29-2009 |
20100169952 | METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR PROVIDING AN ADAPTIVE AUTHENTICATION SESSION VALIDITY TIME - An apparatus for providing an adaptive authentication session validity time period may include a processor. The processor may be configured to receive an indication of load parameters indicative of authentication rate information, determine, at the service platform, a value defining a validity period for indicating a period of time during which an authentication session validity object is valid based on the received indication of load parameters, and provide the authentication session validity object to a client device. A corresponding method and computer program product are also provided. | 07-01-2010 |
20130019299 | Distributed Authentication with Data Cloud - A method includes, in response to a need to access for a user certain stored data that requires authentication, sending a request for the stored data into a data cloud, the request not identifying the user. The method further includes receiving, from the data cloud, response information descriptive of an authentication realm and a single-use nonce; presenting the information descriptive of the authentication realm to the user and prompting the user for a user name and password; re-sending the request into the data cloud with an authentication header having user credentials generated at least in part using the response information, the user credentials comprising the user name and a hashed password; and if the user credentials are valid, receiving from the data cloud the requested stored data. | 01-17-2013 |

20110177805 | Scalable WLAN Gateway - A technique for combining transmission bandwidths of several communication devices, such as mobile stations is disclosed. A master mobile station establishes a WLAN access point communicating with WLAN client terminals. One or more slave mobile stations may detect a predefined network identifier and join the WLAN network. The master assigns IP addresses for the client terminals and slave mobile stations. The master also resolves DNS queries in cooperation with external DNS servers. Traffic, including internet packets, between the client terminals and various internet hosts is tunneled over multiple simultaneous transmission paths between the master and a multiplexing/demultiplexing computer). The inventive bandwidth combination technique is transparent to the client terminals and the internet hosts. | 07-21-2011 |
