  • Patent number: 7462977
    Abstract: A high temperature pressure transducer includes an extended tubular member having an opening from a front to a back surface. The tubular member is preferably fabricated from a metal. At the front end of the tubular member is a ceramic sensor face or tip which basically is a ceramic disk having a curved front surface and having an extending stem and which is inserted into the front opening of the tubular member. The column is of a given length and terminates in a back end. The back end has a predetermined portion which consists of two flat surfaces each on opposite sides. The back end containing the flat surfaces is thinner than the thickness of the column. On these flat surfaces are positioned suitable semiconductor piezoresistors. When a force is applied to the ceramic sensor face, it is transmitted axially through the tube or column where it is received by the sensors positioned on the flats. The sensors produce an output indicative of the force applied.

  • Patent number: 6451610
    Abstract: An activated partial thromboplastin time (APTT) test is described which employs fresh, whole blood that has not been anticoagulated. The method employs a disposable cuvette having specific reagents placed therein. A sample of whole blood is introduced into the cuvette which is drawn into at least one conduit by a pneumatic pump. Initially, the calcium in the sample is chelated at a first reaction site in the conduit, and thereafter is moved through the conduit to a second reaction site where the sample is coagulated by an APTT reagent. After a predetermined incubation time, the sample is moved to a third reaction site where it is recalcified. Clotting time is measured from the time that the sample is recalcified to the time that clot formation is visibly detected.
