A key enrollment method of a physically unclonable function (PUF) circuit including a plurality of PUF cells includes receiving a first level key from PUF cells, performing bit encoding on the first level key using a bit coding table based on Hamming weights of a plurality of bits in the first level key to generate a second level key, storing first helper data associated with the second level key in a non-volatile memory, performing block encoding on the second level key using an error correction code to generate a third level key, and storing second helper data associated with the third level key in the non-volatile memory.

A wedge-base lamp socket comprises a socket body having a lamp holder for holding a wedge-base lamp. The lamp holder includes an outside wall, a pair of opposite receiving portions disposed inside the outside wall and opposed inside walls diametrically extending between the receiving portions. The inside walls define an elongated channel therebetween for receiving a wedge base of a lamp. The opposed inside walls include a pair of opposed recesses adjacent to each of the receiving portions each including a guide groove therein. A pair of terminals are oppositely mounted in the lamp holder. Each terminal has a bracket part received in a respective one of the receiving portions and a pair of clamp arms connected to the bracket part. The clamp arms extend upwardly along both sides of the bracket part and are adapted for clamping the wedge base of the lamp. Each clamp arm is received within a respective recess in the pair of opposed recesses and includes a protrusion on an outer surface of the clamp arm for reception in the guide groove.

A connector for a flexible cable is provided. Connection parts of an even terminal and an odd terminal alternately cross each other to align a rotation center with the center of an X-shape. Operation parts of the terminals are divided into rotation start sections and rotation end sections. Recesses of the rotation start sections are deeper than recesses of the rotation end sections. A stopper prevents reduction of a contact pressure after a rotator engages with the rotation end sections at an angle of 90°.

A heat exchanger, a reinforced header assembly for use in a heat exchanger, and a method of assembling a heat exchanger. The reinforced header assembly may include a header connectable with a tank to define a collection tank assembly, the header including a central portion defining a plurality of header openings, and a connecting portion connectable to the end of the tank wall such that the tank portion and the header cooperate to define the collection tank assembly, the connecting portion including a wall extending at a non-parallel angle relative to the central portion, and a reinforcement member including an inner portion defining a plurality of member openings, and an outer portion extending at a non-parallel angle relative to the inner portion, the outer portion being complementary to and connected to at least a portion of the wall of the connecting portion of the header.
