Abstract:
An electrical connector includes an insulative housing and a number of conductive contacts received in the insulative housing. Each conductive contact has a contacting portion, an engaging portion and an extension portion electrically connecting with the contacting portion and the engaging portion. A node is disposed in the extension portion for matching characteristic impedance of the conductive contact, and a positioning portion is disposed in the insulative housing corresponding to the node for cooperating with the node to restrict movement of the node. The electrical connector in accordance with the present invention can match characteristic impedance of the conductive contact to realize impedance match and can assure precise positioning of the conductive contact.
Abstract:
Transparent monolithic aerogels based on silica, the bioderived polymer chitosan, and coordinated ions are employed to serve as a three-dimensional scaffold decorated with metal ions such as Au, Pt and Pd ions. It has also been found that the metal aerogels, such as Au(III) aerogels, can be imaged photolytically to produce nanoparticles.
Abstract:
An electrical connector comprises an insulative housing, a plurality of terminals assembled to the insulative housing and a pair of fastening elements assembled to the insulative housing. The insulative housing comprises an elongated base portion and a pair of retaining slots respectively disposed at two sides thereof. The base portion defines a mating face and an engaging face opposite to the mating face. A pair of fastening elements are assembled to the pair of retaining slots of the insulative housing, each fastening element comprises a fixing portion received in the retaining slot and a resilient arm disposed outside of the retaining slot and opposite to the fixing portion.
Abstract:
An electrical connector (1) comprises a dielectric housing (2) and a plurality of conductive contacts (3). The dielectric housing (2) comprises a plurality of contact passages (20) having retaining means (206) therein. Each conductive contact (3) comprises a retaining portion (30) engaging corresponding the contact passage (20) and a resiliently depressible contacting portion (34). When inserting, the conductive contact (3) is respectively inserted in the contact passages (20) along an inserting direction while the retaining portion (30) along a first path, the contacting portion (34) along a second path, but the retaining means (206) is not on the first path and second path and engages the inserted conductive contact (2).

Abstract:
Various embodiments of multi input multi output (MIMO) communication systems include a transmit Tomlinson-Harashima Precoding (THP) technique and a single carrier frequency domain equalization (SC-FDE) technique. Parallel THP-FDE and successive THP-FDE are proposed based on the minimum mean square error (MMSE) criterion. For the successive THP-FDE technique, where all transmit streams are subsequently precoded, both suboptimal and optimal MMSE ordering algorithm are set forth. Since the feedback processing is performed at the transmitter, no error propagation problem exists in the THP-FDE MIMO techniques, yielding significant performance improvements over conventional FDE MIMO techniques. Applying channel prediction and THP compensation techniques can also further enhance performance.
