Emission of a signal in resource units to increase energy detection of an 802.11 channel
In an 802.11ax network with an access point, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access point. To avoid the overall energy level seen by legacy nodes for a communication channel to drop below a detection threshold, the invention provides two tools. First, the scheduled and random resource units may be interleaved over communication channels. Second, unused resource units may be detected, and a node or the access point may send a padding signal on them to increase the overall energy level. The latter may be evaluated during a monitoring period before deciding to emit the signal. As the overall energy level seen by legacy nodes is increased, the risk that such legacy nodes do not detect activity on a 20 MHz channel having only a subpart of its RUs used is reduced. And risks of collisions are consequently reduced. |

Detecting interference in depth images captured using overlapping depth cameras
Discrete frequencies and time slots of operation are assigned to each of a plurality of time-of-flight cameras. Where two time-of-flight cameras having overlapping fields of view, whether the time-of-flight cameras are operating at the same frequency or time slot is determined by calculating ratios of zero-value pixels to total numbers of pixels for each depth image captured by the time-of-flight cameras over a selected interval. If the time-of-flight cameras operate at the same frequency or time slot, a plot of the ratios of depth images captured using one time-of-flight camera is erratically sinusoidal. Another time-of-flight camera causing the interference may be identified among time-of-flight cameras operating at the frequency or time slot, based on areas of interest that overlap with the time-of-flight camera, or based on a time at which the time-of-flight cameras began capturing depth images, as compared to a time at which the interference is observed. |

A plug board module with a circuit board, comprising at least one plug board, at least one circuit board and at least one cover. The plug board has a first plug-in area and a board trough, and the first plug-in area is formed with a plurality of first jacks and disposed with least one terminal set. The circuit board is disposed in the board trough and has a side conductive portion and a butt component, and conductive terminals disposed outside the first plug-in area are oppositely disposed in the side conductive portion. The cover covers the plug board and the circuit board, and has a plurality of through holes communicating with the first jacks. Thereby, the plug board can be connected to side conductive slots through the conductive terminals to achieve electrical conduction with the circuit board that is provided for an evaluation board to plug in directly. |

Card edge connector
The present disclosure provides an electrical connector. The electrical connector comprises an insulative housing, a plurality of conductive terminals and a board fastener. The insulative housing has a mounting surface and a mating surface on opposite sides in a mating direction and a mounting chamber. The mounting chamber has a top accommodating portion and a bottom accommodating portion extending and penetrating the mounting surface from the top accommodating portion in the mating direction, two side walls defining the mounting chamber each are formed with a top limiting surface and a bottom limiting surface which define the top accommodating portion. The fastener has a mounting section accommodated in the top accommodating portion, an intermediate section extending from the mounting section and accommodated in the bottom accommodating portion and a tail section extending out of the mounting surface of the insulative housing from the intermediate section. |

Plug contact
A plug contact for electrically contacting a printed circuit board by plugging the contact into a contact hole of the printed circuit board, has two contact limbs which are elastic relative to each other, a terminal region, and a connection region. The connection region connects the contact limbs together and to the terminal region, the plug contact being punched out of flat metal material and bent. The plug contact ensures multiple plugging and pulling cycles without the inner wall of the contact hole being damaged by each of the contact limbs being a contacting region which contacts the contact hole in the plugged-in state. The outer contour of each of the contact limbs is shaped as a segment of a circle in a cross-sectional view in the contacting region, the radius of the outer contour being smaller than the radius of the corresponding contact hole of the printed circuit board. |

Method for securing a terminal within a connector housing of a connector assembly and a connector assembly formed by said method
A method of securing an electrical terminal within a terminal cavity of a connector body is described herein. The method includes the step of deforming a portion of an outer surface of the connector body to fabricate a protrusion that projects from an inner surface of the connector body into the terminal cavity, thereby securing the electrical terminal within the terminal cavity. A connector assembly formed by this method is also described. |
