A battery connector comprises a terminal block and a first and second terminal received in the terminal block. The terminal block comprises a mounting face, a mating face opposite to the mounting face and a receiving cavity locating between the mounting face and the mating face. The first terminal comprises a plate-shaped base, a tail portion extending downwardly from the base, a retaining portion extending upwardly from the base and a resilient arm extending outwardly from the plane in which the base locates. The retaining portion comprises a narrowed elastic arm and a locking portion extending from the elastic arm. By this mean, the battery connector is capable of securely engaging with a coin battery.

A battery connector comprises a terminal block and a first and second terminal received in the terminal block. The terminal block comprises a base, a first protecting wall and a second protecting wall. The base, the first and second protecting wall together defines a receiving chamber. The first protecting wall defines at least a flange; the second protecting wall defines at least a resilient retaining arm relative to the flange. Under the cooperation of the flange and the resilient retaining arm, a reliable electrical connection is established between the first terminal, the second terminal and a coin battery.

An electrical connector comprises an insulatvie housing, a plurality of terminals received in the insulative housing and a pair of retaining members assembled to the insulative housing. The insulative housing has a pair of positioning shoulders at two sides thereof, and each positioning shoulder defines a lower surface and a positioning hole extending there through. Each retaining member defines a main plate covering the lower surface of the positioning shoulder and a though hole corresponding to the positioning hole.

An electrical connector assembly includes an electrical connector unit (11) to be mounted onto a printed circuit board (11), a supporting member for supporting the electrical connector unit, and a pick up device (12) attachable onto the electrical connector unit. The supporting member includes a supporting portion (112) extending from one side of the electrical connector unit, with the supporting portion defining a supporting surface (1121) resting on the printed circuit board. The pick up device includes a balance section (122) defining a balance surface (1221) extending parallel to the supporting surface such that when the pick up device is attached onto the printed circuit board, the balance surface of the pick up device is operable to be rested on the printed circuit board so as to counterbalance force torque caused by introduce of the supporting portion.

Analogs of saquinavir functionalized at the quinoline portion of the molecule are described. These include pyridyl analogs (replacing the quinoline ring) with a functional handle out of the ring allowing for elaboration with linkers terminated by a functional group such as an activated ester which are useful for attaching the molecule to other entities such as proteins, polysaccharides, and the like. Analogs of saquinavir derivatized out of the quinoline ring are also described.

A method of treating particles to be used in immunoassays reduces interference in particle agglutination assays. For particles having covalently bound antibodies and residual NHS-ester or sNHS-ester groups on the surface, the reactive esters are treated with an aqueous mixture containing an amine compound of formula (I): H2N—R—X (I). The moiety —X is —NH2, —OH, or —CO2CH2CH3; and R is an alkyl group or an alkyl ether group. When —X is —NH2 or —CO2CH2CH3, R contains from 1 to 20 carbon atoms; and when —X is —OH, R contains from 4 to 20 carbon atoms.

A wireless communication system includes a plurality of base stations, a plurality of base station controllers and a plurality of mobile switching centers. The plurality of base stations each support wireless communications within a respective cell and service load therein relating to subscribing units operating therein. Each of the base station controllers couples to a plurality of base stations and each of the mobile switching centers couples to at least one base station controller. The plurality of base station controllers and the plurality of mobile switching centers are managed to dynamically route load between the base station controllers and the mobile switching centers in an effort to equalize load on the plurality of mobile switching centers. At least one base station controller of the plurality of base station controllers may route its load to a first mobile switching center during a first period and route its load to the second mobile switching center during a second period. The first period and the second period may correspond to differing time periods and/or differing days. Such periods may be determined based upon historical loadings of the wireless communication system and simulation results. However, in other operations, the load is switched based upon actual system loading and the periods are determined according to the actual system loading. In other operations of the wireless communication system, a base station controller routes its load concurrently to both a first mobile switching center and a second mobile switching center of the plurality of mobile switching centers. In such operations, a first amount of load is routed to the first mobile switching center and a second amount of load routed to the second mobile switching center, such levels determined based upon loading of at least one of the first mobile switching center and the second mobile switching center.

A data processing system implements a load balancing methodology which recognizes the effects that multiple, mobile subscribers have within a wireless communications network. During execution of this load balancing methodology, a rehoming operation is executed at a telephone central office to move some subscribers in a network to a new home mobile switching center with a minimum number of rehoming steps. To perform this rehoming operation, a mobile switching center in a network which has a highest load is selected first. Mobile switching centers which have a load lower than a network average load are considered to be candidates for a rehome destination. All subscriber groups homed to the highest loaded mobile switching center are evaluated to determine whether or not a rehoming operation using this subscriber group would provide a highest benefit and give a lowest standard deviation of loads among mobile switching centers after the rehome operation is selected. This operation is iterative and searches for the best directory number to be homed in each candidate mobile switching center. A resulting balanced load of network resources will serve to increase the effectiveness and longevity of a current wireless communications network before additional equipment is required.
