  • Patent number: 11942716
    Abstract: A configurable electrical connector. The electrical connector includes conductors held by a housing. Contact tails of the conductors extend from a mounting face of the housing therethrough. The mounting face of the housing includes a slot. In some embodiments, the slot exposes portions of ground conductors of the connector and receives a member coupled with the exposed portions of the ground conductors such that the electrical connector can meet high performance requirements. The member may be inserted into or molded in the slot. In some embodiments, the slot may or may not receive a member that is insulative when the electrical connector does not need to meet the high performance requirements. Such a configuration enables the same connector to be compatible with multiple performance protocols.

  • Publication number: 20240015495
    Abstract: An electronic device may include wireless circuitry with first and second receivers. Each receiver may include circuitry for receiving radio-frequency signals using a first radio access technology (RAT) and using second or additional RATs. The wireless circuitry may perform system selection in which the receivers attempt to acquire a signal transmitted by a base station using different RATs. The first receiver and the second receiver may concurrently perform system selection in which the first receiver performs a band scan over the first RAT while the second receiver concurrently performs a band scan over a second or additional RAT. Additional band scans may be performed as needed until a signal is acquired. Once a signal is acquired, the wireless circuitry may establish cellular communications with the wireless base station based on the acquired signal. This may minimize the amount of time required to begin cellular telephone communications in many situations.

  • Patent number: 11870171
    Abstract: A high density edge connector that provides robust operation and good signal integrity. The connector is configurable to have sections tailored for high speed signals, which may be differential, or low speed signals. The connector may be assembled from signal terminals and ground terminals, either of which may be mounted within an insulative housing of the connector at any location along a row aligned with a slot of a mating interface. Shield members or lossy members may optionally be included for high speed segments, either or both of which may be electrically coupled to the ground terminals. Insertion and retention force may be limited, despite a dense array of contacts pressing on a card inserted into the connector by shaping the portions of the signal or ground contacts that act as beams generating that force. Such force may be limited with twists in the beams and/or splitting the beam portions.
