  • Patent number: 8980568
    Abstract: The present invention recognizes that diagnosis and prognosis of many conditions can depend on the enrichment of rare cells, especially tumor cells, from a complex fluid sample such as a blood sample. In particular, the present invention is directed to methods and compositions for detecting a non-hematopoietic cell, e.g., a non-hematopoietic tumor cell, in a blood sample via, inter alia, removing red blood cells (RBCs) from a blood sample using a non-centrifugation procedure, removing white blood cells (WBCs) from said blood sample to enrich a non-hematopoietic cell, if any, from said blood sample; and assessing the presence, absence and/or amount of said enriched non-hematopoietic cell.

  • Publication number: 20090139248
    Abstract: Disclosed is a device for the transport of temperature sensitive products including an insulated container, an insulated lid, a fastener to secure the lid to the container, an active heat exchanger, a thermal circuit to circulate heat exchange, a temperature sensor read by a temperature regulating circuit that maintains a temperature range, a power source, and a support frame that arranges the elements of the device with the overall center of mass at a location adapted for transport and storage of the device. Disclosed is also a method of transport for temperature sensitive products including securing the temperature sensitive product within an insulated container with a lid, removing heat from the container to maintain a temperature range, strapping the device onto the user's back and adjusting to the shape of the user, freeing both hands during transport of the device, and minimizing hindrances to user mobility caused by the device.

  • Publication number: 20080106872
    Abstract: The present invention is directed to a high density test probe which provides a means for testing a high density and high performance integrated circuits in wafer form or as discrete chips. The test probe is formed from a dense array of elongated electrical conductors which are embedded in an compliant or high modulus elastomeric material. A standard packaging substrate, such as a ceramic integrated circuit chip packaging substrate is used to provide a space transformer Wires are bonded to an array of contact pads on the surface of the space transformer. The space transformer formed from a multilayer integrated circuit chip packaging substrate. The wires are as dense as the contact location array. A mold is disposed surrounding the array of outwardly projecting wires. A liquid elastomer is disposed in the mold to fill the spaces between the wires.
