摘要:
An apparatus for programming an electronically programmable semiconductor fuse applies a programming current to a fuse link as a series of multiple pulses. Application of the programming current as a series of multiple short pulses provides a level of programming current sufficiently high to ensure reliable and effective electromigration while avoiding exceeding temperature limits of the fuse link.

A method and apparatus for testing a photovoltaic substrate disposes the substrate on a support gantry with connection points such as vacuum cups. The gantry is actuated into a test position. A probe nest coupled to the gantry connects to a junction box on the substrate. A power supply applies voltage to the junction box, and an actuated frame contacts an edge region of the substrate to detect any breakthrough current. The actuated frame comprises a liner for maximizing contact with the edge of the substrate. The liner may be conductive, or may have a conductive surface. Current sensors coupled to the conductive liner of the frame detect any breakthrough current. A solar spectrum simulator provides solar spectrum radiation for testing the photovoltaic properties of the substrate.

A network device for transferring data from a first network to a second network comprises a switch comprising a first port adapted to receive a frame of the data from the first network and a second port adapted to transmit the frame to the second network. The frame comprises a plurality of words including a first word comprising a first portion of an internet protocol address and a second word comprising a second portion of the internet protocol address. The switch adds one or more bits to the frame so that the first and second portions of the internet protocol address appear within a single word of the frame. A processor receives the frame from the switch, and to modify the internet protocol address in the frame. The switch receives the frame from the processor, and removes the one or more bits from the frame before the second port transmits the frame to the second network.

A semiconductor package includes a die that is interposed, flip-chip style, between an upper lead frame and a lower lead frame. The lower lead frame has contacts that are aligned with terminals on the bottom surface of the die. The upper lead frame contacts a terminal on the top side of the die, and the edges of the upper lead frame are bent downward around the edges of the die, giving the upper lead frame a cup shape. The edge of the upper lead frame contact another portion of the lower lead frame, so that all of the contacts of the package are coplanar and can be surface-mounted on a printed circuit board. The terminals of the die are electrically connected to the lead frames by means of solder layers. The thicknesses of the respective solder layers that connect the die to the lead frames are predetermined to optimize the performance of the package through numerous thermal cycles. This is done by fabricating the lower lead frame with a plurality of mesas and using a double solder reflow process.

A method for configuring an enhanced Node B (eNB) in a long term evolution (LTE) wireless communication network includes providing information to the eNB, wherein the eNB can perform a self-configuration process based on the provided information. An eNB for use in an LTE wireless communication network includes a universal integrated circuit card and a service control module. The universal integrated circuit card includes information that the eNB can use to perform a self-configuration process. The service control module is configured to receive the circuit card and read the information on the circuit card.
摘要:
An oral solid pharmaceutical dosage form comprising an acid sensitive proton pump inhibitor (PPI) as single active drug, releasing the PPI in two separate pulses, one immediate and one delayed. The PPI is formulated into a core material in the form of tablets, which are coated i.a. with a combination of a delay release modifying layer and a lag time controlling layer that together achieves beneficial release properties. The tablets are further provided with an enteric coating layer. The application also relates to processes for preparing the dosage forms as well as their use in the treatment of gastrointestinal diseases.
