| 20100325429 | SYSTEMS AND METHODS FOR MANAGING CRLS FOR A MULTI-CORE SYSTEM - The present invention is directed towards systems and methods for maintaining Certificate Revocation Lists (CRLs) for client access in a multi-core system. A first core may generate a secondary CRL corresponding to a master CRL maintained by the first core. The CRLs may identify certificates to revoke. The first core can store the secondary CRL to a memory element accessible by the cores. A second core may receive a request to validate a certificate. The second core can provisionally determine, via access to the secondary CRL, whether the certificate is revoked. The second core may also determine not to revoke the certificate. Responsive to the determination, the second core may request the first core to validate the certificate. The first core can determine whether to revoke the certificate based on the master CRL. The first core may send a message to the second core based on the determination. | 12-23-2010 |

| 20110154017 | SYSTEMS AND METHODS FOR EVALUATING AND PRIORITIZING RESPONSES FROM MULTIPLE OCSP RESPONDERS - The present invention is directed towards systems and methods for determining a status of a client certificate from a plurality of responses for an Online Certificate Status Protocol (OCSP) request. An intermediary device between a plurality of clients and one or more servers identifies a plurality of OCSP responders for determining a status of a client certificate responsive to receiving the client certificate from a client during a Secure Socket Layer (SSL) handshake. Each of the plurality of OCSP responders may transmit a request for the status of the client certificate to a uniform resource locator corresponding to each OCSP responder. The intermediary device may determine a single status for the client certificate from a plurality of statuses of the client certificate received via responses from each uniform resource locator. | 06-23-2011 |
| 20110154018 | SYSTEMS AND METHODS FOR FLASH CROWD CONTROL AND BATCHING OCSP REQUESTS VIA ONLINE CERTIFICATE STATUS PROTOCOL - The present invention is directed towards systems and methods for batching OCSP requests and caching corresponding responses. An intermediary between a plurality of clients and one or more servers receives a first client certificate during a first SSL handshake with a first client and a second client certificate during a second SSL handshake with a second client. The intermediary may identify that the statuses of the client certificates are not in a cache of the intermediary. An OCSP responder of the intermediary may transmit a single request to an OCSP server to determine the statuses. The intermediary may determine, from a single response received from the OCSP server, whether to establish SSL connections with the clients based on the statuses. The intermediary may store the statuses to the cache for determining whether to establish a SSL connection in response to receiving a client certificate from the first client. | 06-23-2011 |
| 20110154026 | SYSTEMS AND METHODS FOR PARALLEL PROCESSING OF OCSP REQUESTS DURING SSL HANDSHAKE - The present invention is directed towards systems and methods for processing an Online Certificate Status Protocol (OCSP) request in parallel to processing a Secure Socket Layer (SSL) handshake. The method includes transmitting, by an OCSP responder of an intermediary device between a plurality of clients and one or more servers, an OCSP request to a OCSP server for a status of a client certificate responsive to receiving the client certificate from a client during a SSL handshake. The intermediary device may continue to perform remaining portions of the SSL handshake while the OCSP request to the OCSP server is outstanding. The intermediary device may establish an SSL connection for the SSL handshake. The intermediary device may determine whether to terminate or maintain the established SSL connection based on the status of the client certificate received via a response from the OCSP server. | 06-23-2011 |

| 20090292792 | MANAGEMENT INFON, METHOD AND SYSTEM FOR WORKFLOW MANAGEMENT IN A COMMUNICATIONS NETWORK - The invention relates to a computer readable medium containing a management infon modeling an execution result of a management activity in a communications network. The management infon comprises a descriptor of the management activity, at least one value representing a managed object involved in the management activity and an indication of the execution result of the management activity. The invention further relates to a method for workflow management in a communications network comprising the steps of executing a management activity defined by at least one workflow, creating a management infon modeling an execution result of the management activity and managing said at least one workflow using said management infon. The invention also relates to a computer system in a communications network comprising a processor for executing a function creating a management infon modeling an execution result of a management activity. | 11-26-2009 |

| 20100076692 | Movement And Event Systems And Associated Methods - A method for monitoring fractional weight supported by one foot of a person, comprising the steps of adhering a movement monitor device underneath the foot such that the device is compressed when weight is applied to the foot; generating wireless signals representative of a target fractional weight of a total weight of the person; remotely receiving the wireless signals as information of the fractional weight. A method of monitoring weight of a person, comprising the steps of arranging one or more weight sensitive detectors underneath a foot of the person; processing signals from the detectors to determine weight; and wirelessly communicating the weight to a remote receiver. | 03-25-2010 |

| 20090256015 | Attenuation of pressure variations in crushers - A crusher system, including a first crushing surface and a second crushing surface which are operative to crush material between them. A hydraulic system is operative to adjust a gap between the first crushing surface and the second crushing surface by adjusting a position of the first crushing surface with a hydraulic cylinder connected to the first crushing surface. The hydraulic system includes an accumulator connected to the hydraulic cylinder by a hydraulic liquid conduit. The accumulator includes a hydraulic liquid chamber and a gas chamber separated from the hydraulic liquid chamber. The accumulator has a preloading pressure that is the pressure of the gas chamber when the hydraulic liquid chamber is empty, which is at least 0.3 MPa lower than a mean operating pressure of the hydraulic cylinder, such that the accumulator is active and variations occurring in the hydraulic pressure of the hydraulic cylinder during operation of the crusher system are attenuated. | 10-15-2009 |

| 20110217162 | TURBO CHARGER HOUSING - A turbocharger compressor housing apparatus comprises a compressor housing and diffuser. These components are configured to provide an interference fit when assembled. An annular projection extends outwardly from one of such components toward the other of the components and engages the other of the components to form an annular joint. One of the compressor housing and diffuser comprises a recess positioned to collect debris generated during the interference fit to prevent the debris from reaching the annular joint. A second recess can be provided at the opposite side of the projection to accommodate deformation of the projection during assembly of the diffuser and compressor housing. The recesses can be annular and can, along with the projection, be included in the diffuser. | 09-08-2011 |
