The socket structure comprises: a socket structure housing defining a cavity therein; and an interconnection structure including: a contact element disposed at least in part within the cavity, and configured to be electrically coupled to a corresponding microelectronic package, the contact element corresponding to one of a signal contact element or a ground contact element; and a conductive structure disposed at least in part within the cavity, electrically coupled to the contact element, and having an outer contour that is non-conformal with respect to an outer contour of the contact element.

A power delivery system for a hardware processor includes a motherboard (MB), a voltage regulator (VR), an elastomer computer socket, and a plurality of power delivery paths within the socket. The socket connects the MB to the processor and comprises a first set of power pins that is connected to the processor by surface mount elements, and a second set of power pins that is not connected to the processor by surface mount elements. The plurality of electrical power delivery paths deliver VR power from the second set of C power pins to the first set of power pins for power delivery to the processor. The alignment frame aligns the processor, the plurality of power pins, and the MB. The plurality of power paths alone may meet the power demands of the processor. If not, a power plane from the MB provides additional power.

A light assembly system includes a light assembly and a software reflash kit for updating software of an internal control unit of the light assembly. The light assembly is constructed for releasable receipt of an electrical communication device of the software reflash kit. The light assembly includes a housing, the control unit, and an access port. The housing defines an enclosed, sealable, chamber. The control unit is located in the chamber. The access port is defined by and communicates through, the housing, and is adapted to receive the electrical communication device for detachable electrical engagement to the control unit.

A biosignal measurement system comprises an adapter for a biosignal measurement device, and an external support structure separate from the adapter. The adapter comprises tool-less connectors, which are repeatedly connectable to and disconnectable from their counter connectors of the external support structure, and a device connector, which has an electrical connection with the tool-less connectors and which has a connection with the biosignal measurement device that the adapter carries. The external support structure comprises an electrode support structure with electrodes and tool-less counter connectors, the electrodes and the tool-less counter connectors having an electrical connection therebetween. The electrodes form an electrical contact with skin for receiving the biosignal. The counter connectors are in electrical contact with the connectors of the adapter for transferring the biosignal to the biosignal measurement device through the adapter.

A connector is mounted on an input-output board. The connector is interposed between the input-output board and a CPU board, and thereby a plurality of pads of the input-output board and a plurality of pads of the CPU board are respectively electrically connected. The connector includes a rectangular flat-plate housing having a first positioning hole and a second positioning hole, and at least one contact row held on the housing. The first positioning hole is formed at a first housing corner part of the housing. The second positioning hole is formed at a fourth housing corner part, which is at a diagonal position with respect to the first housing corner part, of the housing.
