  • Patent number: 8269979
    Abstract: A device detects underfill voids and solder ball defects via laser generation and laser detection of an ultrasonic wave at the top surface of flip chips. High resolution is provided by using small laser spot sizes and closely-spaced laser beams of wavelengths that are absorbed near the surface of the semiconductor. Improved spatial resolution and rejection of unwanted scattered waves can be attained by limiting the time frame of the ultrasonic waveform to the time required for the first longitudinal wave reflection from the bottom of the flip chip. The laser beam spacing can be reduced by using probe and detection beams of different wavelengths. Resolution of less than 100 ?m features was demonstrated for silicon flip chips.

  • Patent number: 8195200
    Abstract: A mobile rover has a navigation receiver receiving radio positioning data from radio positioning entities. The mobile rover can report its position to a mobile controller unit or another entity so that the location of the mobile unit can be tracked based on the radio positioning data received by the mobile rover. The radio positioning data can be processed by processing systems within the mobile rover, mobile controller, or other entities such as a position determination entity or a position determination entity proxy. The processing systems can also perform calculations to augment the radio positioning data to provide more accurate estimates of the position of the mobile controller and/or the mobile rover. The mobile controller and/or the mobile rover may be cellular telephones within a cellular network.

  • Patent number: 8149421
    Abstract: Faults, dimensions and other characteristics of a material or structure are sensed by a coherent beam's reflection from the material when probed with ultrasonic waves or when vibrating at high frequencies. The reflected beam acquires a dynamic phase change substantially different from its original phase and from the phase of a reference beam split from the common source beam. The reflected beam and the reference beam are superimposed by diffraction in an adaptive holographic beam-splitter, and the superimposed beams are detected by a photodetector capable of detecting small phase changes from ultrasonic surface displacements or perturbations. An apparatus and method are disclosed defining an improved crystal homodyne interferometer with an energy source coupled to the crystal and operative to maintain the crystal in a condition for emptying unwanted traps in the crystal.

  • Patent number: 8115807
    Abstract: Apparatus for determining the status of hair bulk in an area of a scalp is operative to provide a metric over a sufficiently large area to permit revisiting with only negligible misalignment error. Accurate re-measurement of hair status in accurately identified areas produces a reliable metric for determining degree of hair loss and or the effectiveness of treatment.

  • Patent number: 8017219
    Abstract: The present invention provides a process for making a mineral battery using treated powdered polar crystal mineral and a treated liquid as an electrolyte. The polar crystal powder and liquid are either separately or after mixing together subjected to a rotating EMF. The powder-liquid mixture is inserted into a housing and compacted therein to form a mineral battery, along with an anode and a cathode and terminals. The preferred polar crystal mineral is tourmaline. In one embodiment, after the mixture is in the housing it is subjected to a voltage. In one embodiment the mixture is prepared and compacted into the housing and then subjected to a rotating EMF, and may then also be subjected to application of a voltage.

  • Patent number: 7897057
    Abstract: A gas sensor system and its method of fabrication is disclosed. The sensor system comprises an optrode, light source, and a light detector. In a sensor for hydrogen gas, the optrode is comprised of a porous substrate into which an intimate mixture of reagent and catalyst is incorporated. The mixture reacts with the hydrogen to produce a color/intensity change in relation to the concentration of gas. The optrode further includes a reversing agent, boron, to restore the benchmark conditions of the sensor system in real-time. The method of fabricating the optrode includes the steps of cleaning; etching to achieve the proper porosity; incorporating the reagent, catalyst, and reversing agent using capillary action; and removing excess reagent and catalyst.
