  • Patent number: 7468727
    Abstract: Methods for visualizing a graph by automatically drawing elements of the graph as labels are disclosed. In one embodiment, the method comprises receiving node information and edge information from an input device and/or communication interface, constructing a graph layout based at least in part on that information, wherein the edges are automatically drawn as labels, and displaying the graph on a display device according to the graph layout. In some embodiments, the nodes are automatically drawn as labels instead of, or in addition to, the label-edges.

  • Patent number: 7056724
    Abstract: Current technologies allow the generation of artificial DNA molecules and/or the ability to alter the DNA sequences of existing DNA molecules. With a careful coding scheme and arrangement, it is possible to encode important information as an artificial DNA strand and store it in a living host safely and permanently. This inventive technology can be used to identify origins and protect R&D investments. It can also be used in environmental research to track generations of organisms and observe the ecological impact of pollutants. Today, there are microorganisms that can survive under extreme conditions. As well, it is advantageous to consider multicellular organisms as hosts for stored information. These living organisms can provide as memory housing and protection for stored data or information. The present invention provides well for data storage in a living organism wherein at least one DNA sequence is encoded to represent data and incorporated into a living organism.

  • Patent number: 6384366
    Abstract: A method and apparatus are provided for reliably heating the bonding areas of a substrate and/or a die or dies of a stacked die assembly or a flip-chip assembly to ensure high-quality solder or wire bonds between the substrate and the die. Embodiments include heating the wire bonding areas of the dies of a stacked die package with infrared radiation with an infrared lamp or gun directed towards the top surfaces of the dies before and during the wire bonding process, or heating the bonding pad area of the top surface of a substrate to which a flip-chip is to be mounted from above with infrared radiation from a lamp or gun to the desired temperature, then bonding the flip-chip to the substrate. The use of infrared radiant heating directed at the top surfaces of the dies and/or the substrate ensures that their respective bonding areas are heated to the proper temperature within the necessary time period, thereby enabling high-quality wire bonding or die bonding, and increasing yield.

  • Patent number: 6376265
    Abstract: A method and apparatus is provided for bonding a semiconductor die to a substrate, such as bonding an upper die to the lower semiconductor die of a stacked die assembly. Embodiments include a die bonder with an air pressure sensor for directing a jet of air to the top surface of the lower die. The air pressure sensor generates a signal indicative of the height of the top surface of the lower die based on the back pressure of the jet of air, and sends the signal to a controller for accurately setting the descending height of the upper die onto the lower die to produce the required gap between the two dies for die bonding. Since the sir pressure sensor only contacts the substrate with a relatively small jet of air, the top surface of the lower die is not damaged by the sensor. Because the air pressure sensor accurately measures the height of the lower die, the upper die is placed above the lower die with the proper gap, despite variations in the height of the lower die.
