Abstract: An electronic device such as a laptop computer may have an upper housing and a lower housing. The lower housing may have a clutch barrel. The upper housing may be coupled to the clutch barrel by a hinge. The lower housing may have an upper metal wall separated from the upper housing by a first gap and a lower metal wall separated from the upper housing by a second gap. The clutch barrel may include a conductor. An antenna may be formed from a radiating slot in the conductor. The radiating slot may have a tunnel extending from a first opening to a second opening in the conductor across a diameter of the conductor. The tunnel may be linear or non-linear. The tunnel may have a uniform or tapered width. The radiating slot may convey radio-frequency signals through both gaps regardless of the orientation of the upper housing.

Abstract: An electronic device such as a laptop computer may have an upper housing and a lower housing. The upper housing may be coupled to the lower housing by a hinge. The upper housing may be rotatable relative to the lower housing between an open position and a closed position. The lower housing may have an upper metal wall, a lower metal wall, and a metal sidewall that couples the lower metal wall to the upper metal wall. The lower metal housing may have a finger scoop in the metal sidewall. The finger scoop may have a surface that is oriented at a non-parallel and non-perpendicular angle to a lateral surface of the upper housing when the upper housing is in the closed position. The device may have an antenna with a radiating slot in the surface of the finger scoop.

Abstract: An electronic device such as a laptop computer may have an upper housing and a lower housing. The lower housing may have a clutch barrel coupled to the upper housing by a hinge. The upper housing may be rotatable relative to the lower housing between an open position and a closed position. The upper housing may have a curved metal surface facing the clutch barrel. The device may have an antenna with a radiating arm on a curved interior surface of a substrate in the clutch barrel. The radiating arm may extend parallel to the curved metal surface. The radiating arm may remain separated from the curved metal surface across its lateral area as the upper housing is rotated from the open position to the closed position. This may ensure that the antenna is provided with a uniform capacitive load from the upper housing at all upper housing positions.

Abstract: Seal assemblies, gaskets, bearing assemblies, and their components can be used as pre-packaged seal systems and pre-packaged seal and bearing systems. The seal assemblies can be orientated in different configurations for different applications. Gaskets to restrict flow and gaskets with memory lips to operate as sealing lips can be included to increase the number of sealing points. In a pre-packaged configuration, the cylinder can be a straight cylinder, a stepped cylinder, or a split cylinder. Bearing assemblies can be pre-packaged with the sealing assemblies and service grease may optionally be used to provide lubrication and limit fluid incursion into the spring cavities.

Abstract: Connector receptacles that can provide a robust and reliable connection to a board and have a small form factor. An example can provide connector receptacles that provide a robust and reliable connection to a board by providing contacts having highly planarized solder tails. The solder tails can be supported by extensions of housing portions to provide consistent placement and alignment, as well an amount of shock absorption. The solder tails can include chamfered surfaces to improve soldered connections to pads of a board. The chamfered surfaces can also enable a reduced pitch between solder tails thereby helping to provide a reduced form factor.

Abstract: Seal assembly designs for extreme temperatures that include material and structural designs to counteract sealing component shrinkage or expansion caused by thermal expansion or contraction. Provisions can be included to increase sealing stress along the outer seal lip of the seal assembly for low temperature applications where shrinkage can be an issue and to increase sealing stress along the inner seal lip of the seal assembly for high temperature applications where expansion can be an issue.
