  • Patent number: 10404776
    Abstract: A method for extending a functionality of a computing device programmed to obtain physiological measurements from a patient includes: registering, at the computing device, a plug-in module, the plug-in module providing additional functionality for the computing device; using the plug-in module to communicate with a medical device; commanding the medical device to obtain physiological information from a patient; receiving data associated with the physiological information from the medical device; and transferring the data to a central repository.

  • Patent number: 4529137
    Abstract: A refiner comprising a housing having a refining chamber providing a flow path for particulate material to be refined while travelling between an upstream inlet and a downstream outlet. A refining assembly in the chamber has a series of relatively rotatably cooperative axially confronting annular refining surfaces located on partially internested refining disks and defining radially extending refining zones therebetween and with radially opposite ends of the zones closed. Passages defined by and between the internested portions of the disks connect the adjacent refining zones in a manner to cause the particulate material such as paper making stock to pass successively between the radially outer ends of the zones and the radially inner ends of the zones.

  • Patent number: 4190799
    Abstract: The magnitude and sign of the Hall angle of the material of a wafer (13) are measured by a combined capacitive and inductive coupling technique which does not require physically contacting the wafer (13). Contacting methods in common use introduce surface damage or contamination which may reduce the yield of microelectronic circuits on semiconductor wafers and normally in addition require special sample geometries. In this technique an rf signal is applied to a pair of concentric planar electrodes (11,12) adjacent to the wafer (13), thus capacitively coupling a radial rf current into the wafer. A magnetic field applied perpendicular to the wafer produces a circular component of rf current because of the Hall effect. This circular rf current produces an axial rf magnetic field which couples to a pickup coil (15). The pickup signal is amplified and detected to produce an output signal related to the sign and magnitude of the Hall angle of the wafer material.
