Abstract: Methods and compositions are described using tryptophan analogs, indole analogs, and mixtures thereof as agents for selecting plant cells that have been transformed with an anthranilate synthase (ASA2) gene or a fragment thereof, where the ASA2 gene encodes a feedback-insensitive form of anthranilate synthase (AS).

Abstract: An electrical connector (100) includes an insulative housing (1), a number of contacts (2) retained in the insulative housing (1) and a front metal shell (3) covering a front side of the insulative housing (1). The insulative housing (1) has a body portion (11), and a positioning slot (141) located at a lower side thereof. The front metal shell (3) has a base portion (31) and a board lock (5) integrally extending backwardly from a lower end of the base portion (31). The board lock (5) has a flat securing portion (51) which is received in the positioning slot (141) for preventing the board lock (5) from moving along an up to down direction, and a locking leg (52) bending downwardly from an inner side of the securing portion (51).

Abstract: An electrical connector includes an insulative housing having a front mating face, a base portion, a mating portion protruding forwardly from the base portion and a number of passageways recessed rearward from the front mating face, the housing defining a number of blocks on a rear side thereof, the blocks each having an abutting face on a lower end thereof; a number of first contacts received in the passageways respectively and each including a contacting portion exposed in the passageway to mate with a corresponding mating connector, a level retaining arm fixed in the passageway and defining a front end connecting with the contacting portion and a rear end opposite to the front end, and a vertical mounting portion extending downwardly from a rear end of the retaining arm, the vertical mounting portion including a soldering portion to be soldered onto a printed circuit board and a protrusion tab extending laterally to have a larger width than that of the soldering portion, the protrusion tab abutting against

Abstract: An electrical connector assembly (100) includes a bracket (1) comprising a partition bar (10) and a pair of lower stands (12) extending downwardly from two opposite sides of the partition bar (10), a first electrical connector (2) located on the partition bar (10). The first electrical connector (2) includes a housing (20) defining a plurality of passages (207), a plurality of terminals (21) inserted into the passages (207), and a shell (22) covering the housing (20). The housing (20) is positioned above the partition bar (10). The bracket (10) further includes a lower receiving space (120) disposed under the partition bar (10) and the lower stands (12) there between. The passages (207) include a plurality of first passages (2071) arranged in three rows and a second passage (2072) different from the first passages (2071). The first passages (2071) and the second passage (2072) formed on opposite sides of the first housing (20).

Abstract: An electrical connector (100) includes an insulative housing (1), a plurality of contacts (2) retained in the insulative housing (1), a metal shell (3) partially enclosing the insulative housing, a pair of board locks (4) and a pair of fasteners (5) for assembling the board locks (4) and the metal shell (3) onto the insulative housing. The fastener (5) includes a resisting portion (51) abutting against the metal shell and a rivet portion (53) extending through the board lock. The rivet portion (53) is hollow to form a recess (531) therein and defines a plurality of notches (530) to separate the rivet portion (53) into several discontinuous parts which is riveted to abut against the board lock.

Abstract: An electrical connector (100) includes an insulative housing (10), a number of contacts (20) retained in the insulative housing, a metal shell (30) shielding the insulative housing, and a pair of board locks (40). The insulative housing has a body portion (11) and a mating portion (12). The body portion defines a pair of receiving spaces (14) extending therethrough. Each board lock has a first plate (41) with a hollow cylinder (44) and a hook section (42) extending out of the insulative housing. The metal shell defines a pair of through holes (33) corresponding to the hollow cylinders respectively. The metal shell and the insulative housing sandwich the first plates of the board locks therebetween.

Abstract: A method and apparatus for identifying a faulty device through generation of status messages within each device and monitoring the status messages of each other device. If status messages are not properly received, the apparatus invokes a fault analysis routine to identify the problem. The status messages are transmitted between the devices using a plurality of communications channels.
