Abstract: A method for using a health information exchange system which stores patient record data regarding a multiplicity of patients, to serve a first plurality of EMRs each interacting with an EMR community including a set of at least one EMR, the method comprising: for each individual EMR within the first plurality of EMRs, performing a computerized context interception process using a processor to intercept context from the individual EMR and to identify therewithin an event whereby a health provider using the individual EMR calls up an individual patient's record from said individual EMR; and responsive to identification of the event, using a computerized output device for providing patient record data, pertaining to the individual patient, to the health provider.

Abstract: A health information exchange system comprising ontological apparatus for defining and storing ontological link elements ontologically linking between individual health care information items within a first population of health care information items; apparatus for receiving a second population of health care information items and for associating at least some individual items in the second population, with corresponding individual items within the first population of health care information items; and apparatus for responding to queries regarding particular information items in the second population including translating the particular information items into items in the first population corresponding to the particular information items and using link elements linking the items in the first population corresponding to the particular information items to generate data pertaining to the particular information items in the second population.

Abstract: An oil seal unit for disposition between mating parts having opposed end face sealing surfaces. The seal unit has a casing with a radial flange having opposed end face surfaces and an inner margin portion. An elastomeric seal body with radially inner, outer and intermediate body portions is bonded to the casing. The seal body includes a radially space apart, continuous circular sealing ribs over lying each face of the casing; the seal body also has a radially inner portion defining an opening through which the shank portion of the mating part extends. The intermediate part of the seal body includes a collar element which deforms into snug fluid-tight sealing engagement within a recess defined in part by the seal and in part by portions of the mating parts.

Abstract: A composite drain plug comprising a metal plug element and an elastomeric seal element. The plug element includes a body with a head portion defined in part by exterior, tool-engaging flank surfaces, a radially enlarged, seal positioning flange with an outer diameter surface and a seal-engaging end face surface. The plug also includes a threaded fastening shank, and a depth stop shoulder with a radial end face surface and an axial offsetting surface. The elastomeric seal element includes a seal body integrally bonded to the positioning flange and to offsetting shoulder surface on said depth stop. The seal body also includes a radially extending, axially inwardly directed end face primary sealing surface, lying axially inwardly of the end face of the depth stop.
