Wide bandwidth favored channel access methods in wireless local area networks
A method to improve channel access opportunity for wide bandwidth transmission in wireless local area networks is proposed. The method allows different clear channel assessment (CCA) thresholds for different transmission channel bandwidth. During a primary channel CCA process, a low CCA threshold level is applied for an intended narrow transmission channel bandwidth, while a high CCA threshold level is applied for an indented wide transmission channel bandwidth. In addition to the “all bandwidth transmission branch” that is based on the low CCA level, the “wide bandwidth transmission branch” is based on the high CCA level, which increases the opportunity for channel access by raising the CCA levels based on intended transmission channel bandwidths. As a result, the likelihood of wide channel transmission is increased. |

A multi-tier platform provides security at a perimeter of a computer system, where an intermediate layer interacts between a web layer and an application layer. A data request that is associated with a data set is received at the web layer and passed to the intermediate layer.

If the value is static, the intermediate layer accesses the value stored at the intermediate layer. However, if the value is dynamic, the intermediate layer queries the source registered to the data set, obtains the value from the authoritative source, and returns the dynamic value via the web layer, where the registered source may be internal or external to the computer system. Consequently, the intermediate layer may function as an aggregate layer that supports both database and messaging services. |

Virtual network interface controller performance using physical network interface controller receive side scaling offloads
Techniques disclosed herein provide an approach for using receive side scaling (RSS) offloads from a physical network interface controller (PNIC) to improve the performance of a virtual network interface controller (VNIC).

A blind source separation (BSS) system comprises means for gathering wideband signal power spectral information without using special Fourier transform hardware/software systems and without using extremely large signal memories. The method involves taking the combined energy output of a large set of BSS filters that are operating under a blind source separation algorithm that looks for signals of interest, along with instantaneous filter characteristics such as center frequency, bandwidth and spectral response, and records a weighted spread energy into a frequency- and time-based histogram. This information can then be used to compare against the BSS signal output and signal energy which does not correspond to existing signal output is added to additional BSS signal output. This system can operate in real time, but uses long-term averaging to enhance signal detection. |

Release tab for an electrical connector and electrical connector comprising said release tab
The present invention relates to a release tab (37) for an electrical connector (1), comprising a body (38) and an unlocking nose (42) for unlatching a latch (13) securing the electrical connector (1) connected with a mating connector (2), as well as to an electrical connector (1) comprising a housing (4), a latch (13) for securing the housing (4) to a mating connector (2), the latch (13) extending from the housing (4), having an opening (19), as well as being transferable to an unlatched position, and a release tab (37) being arranged movable between a released position and an actuated position, and having an unlocking nose (42) extending into the opening (19) to transfer the latch (13) to the unlatched position when moving the release tab (37) from the released position to the actuated position. For providing an improved release tab and an improved electrical connector of a simple and compact design, allowing the connector to be unplugged in high density applications, the unlocking nose (42) is arranged at a cantilever (41) projecting from the body (38), and the release tab (37) of the present invention is arranged at the electrical connector. |

Modular plug connector
The disclosure relates to a modular plug connector comprising a metal housing and an insulating holding frame received therein. At least one plug connector module is received in the holding frame, comprises a metallic or at least electrically conductive material, and is electrically insulated from the housing by the holding frame. Furthermore, an earthing device, which bridges the holding frame and permits an electrical contact between the plug connector module and the metal housing, is provided on the plug connector module. This allows different plug connector modules to be held in the holding frame insulated from the housing, and at the same time others to be held in electrical contact with the housing. |
