Abstract: Reliable connector assembly and housing thereof. The housing may include a first portion having first spaces for receiving first connectors and a second portion having second spaces connected to the first spaces for receiving second connectors configured to mate with the first connectors. The first portion comprises a platform comprising a surface in a plane perpendicular to the mating direction at an interface of the first portion and the second portion. Such a configuration reduces the risk of exerting excessive force onto the connectors and increase the reliability of the connector assembly.

Abstract: A reliable socket connector. The connector includes an insulative body having a slot recessed from a mating face and terminals disposed in the insulative body having mating ends curving into the slot and tail ends extend thereout. A shell is disposed outside the insulative body. The shell has a mating portion extend beyond the mating face of the insulative body. The shell has a side wall comprising a docking portion and a guiding portion. The docking portion has holes configured for receiving a latch of a mating plug connector. The guiding portion extends beyond the docking portion in a mating direction and is configured for guiding the mating plug connector into the shell where a mating portion of the plug connector may then be guided into the slot of the insulative body.

Abstract: Reliable connectors configured for easy locking/unlocking. A connector can include a first end configured to mate with a first mating component in a first direction, and a second end configured to mate with a second mating component in a second direction perpendicular to the first direction. The connector can include a locking member configured to move between locked and unlocked positions by a force applied in a third direction perpendicular to both the first and second directions. Such a configuration reduces the risk of interfering with connections between the mated components when applying the force and therefore provide more reliable connectors. The connectors can include a shell with a guiding structure to reduce the risk of damage to lightweight connectors that might otherwise be damaged due to misalignment during mating/unmating. Such a shell can be used with locking members configured for using within electronic systems with densely packed components.

Abstract: An evaluation method of sleep quality and a computing apparatus related to sleep quality are provided. In the evaluation method, sensing data is obtained. The sensing data is generated based on a radar echo. The sensing data is transformed into feature data. The feature data includes a statistic of a plurality of feature points on a waveform of the radar echo. Sleep quality information is determined according to the feature data. Accordingly, sleep quality may be evaluated through non-touch sensing.

Abstract: A connector configured to connect densely disposed cables to a board. The connector may include two or more rows of terminals held by a housing such that the two or more rows of terminals are at a same height with respect to a board that the connector would be mounted to. Such a configuration enables the connector to fit into a space limited by, for example, another component mounted to the board. The terminals may include first contact portions configured to be mounted onto a surface of the board when pressure is applied to the terminals so as to avoid the use of materials that may cause undesired shorting such as soldering materials. The terminals may include second contact portions configured to receive the cables. The second contact portions of ground terminals of a same row may be connected by a strip configured to contact shields of cables attached to the row.

Abstract: A receptacle connector having a plurality of airflow holes positioned to avoid heat buildup inside a receptacle shell, preventing deformation to the housing of a short, high density connector during solder reflow. The airflow holes may be in a bent portion joining a top face and rear face of the shell. The receptacle connector may be mounted to a substrate, such as a printed circuit board, leaving a gap between the connector and the substrate, forming an airflow passage between the substrate and the receptacle connector, enabling heated air to reach mounting portions of terminals of the connector during soldering, but reducing heat buildup within the shell. The passage, alone or in combination with a cutout in a face of the shell, may expose terminal contacts of the receptacle connector to provide for easy inspection and rework of the solder joints between the terminal contacts and the substrate.

Abstract: A connector assembly configured for compact, high speed electronic systems. The assembly includes a board connector and a cable connector that may be mated by moving the cable connector in a mating direction perpendicular to a printed circuit board to which the board connector is mounted. The cable and board connectors may latch when mated and may be unlatched and unmated by pulling on a tab at a top of the cable connector in a direction opposite the mating direction. As a result, little clearance is required around the board connector to access the latching components. Such a connector may enable an electronic device with high signal integrity because the connector can be mounted close to an electronic component that processes high speed signals, providing a short, and high integrity signal paths for high speed signals.

Abstract: A connector assembly with latching provided by a rotating latch bar. The connector has a low height, with the rotating latch bar providing secure engagement between mated connectors of the connector assembly. The latch bar may be shaped to provide spring force that urges the mated connectors together. The connector assembly may be formed with a cable connector and a board connector. The low height of the board connector enables the connector to be mounted close to high speed electronic components, such as a processor, even if covered by a heat sink, as the connector may fit under the heat sink. The cable connector may be coupled, via a cable, to an I/O connector or other component remote from the high speed electronic component.
