Abstract: A connector assembly is provided and includes a circuit board, an elastic connector, a cage, and a heat exchanger. The circuit board includes a heat exchanger opening passing there through. The elastic connector is positioned about the heat exchanger opening. The cage includes a bottom cage with a cage opening facing a first surface of the circuit board. The heat exchanger is positioned on the bottom cage, such that one side of the heat exchanger passes through the cage opening to protrude inside the cage and an opposite side of the heat exchanger passes through the heat exchanger opening to protrude from a second surface of the circuit board opposite to the first surface.

Abstract: An insulating housing for receiving an electronic apparatus has an upper housing, a lower housing connected to the upper housing, and a device receiving space positioned between the upper housing and the lower housing. Two upper sidewalls are positioned on opposite edges of the upper housing. Two lower sidewalls are positioned on opposite edges of the lower housing, each of the lower sidewalls being connected with one of the upper sidewalls. Each lower sidewall has a first lower sidewall, and a second lower sidewall independent from the first lower sidewall that is positioned proximate to a device receiving end of the insulating housing.

Abstract: A stacked electrical connector having an insulation body, a plurality of contacts, an external case, and an internal case. The insulation body includes a pair of plugs and a separation member disposed between the pair of plugs for separating the pair of plugs. The plurality of contacts are disposed on the pair of plugs. The external case encloses the insulation body, while the internal case encloses the separation member. The internal case has at least two support legs extending out of the external case from two sides of the internal case respectively, to secure the electrical connector on a circuit board. By providing the support legs on the internal case, the material cost of the connector can be reduced and the workability of the support legs can be improved.

Abstract: Systems and methods for generating check node updates in the decoding of low-density parity-check (LDPC) codes use new approximations in order to reduce the complexity of implementing a LDPC decoder, while maintaining accuracy. The new approximations approximate the standard float-point sum-product algorithm (SPA), and can reduce the approximation error of min-sum algorithm (MSA) and have almost the same performance under 5 bits fix-point realization as the float-point sum-product algorithm (SPA).
