Abstract: In a method, a user at a client device may be provided with a user interface having user interactive controls, including a control to enable selection from among a plurality of disease groups. Each disease group may correspond to a respective set of two or more individual disease codes. A user selection of a disease group of interest may be detected. The set of individual disease codes corresponding to the disease group of interest may be used to identify a set of encounters associated with a patient cohort. The user may be provided with an indication of a number of unique patients in the patient cohort, a number of patients in the cohort having particular characteristic(s), a total number of encounters in the set of encounters associated with the cohort, and/or a number of encounters, in the set of encounters associated with the cohort, having particular encounter characteristic(s).

Abstract: A seal is provided for sealing a hollow shaft, where the hollow shaft has an inner surface that may be uneven due to shot peening. The seal includes an axially extending ring section having a first end, a second end, an inner surface, and a disk section disposed substantially perpendicular to the ring section inner surface between the ring section first and second ends. The seal conforms to the shaft inner surface to stop oil leakage.

Abstract: In one embodiment, and by way of example only, a seal is provided for sealing a hollow shaft, where the hollow shaft has an inner surface that may be uneven due to shot peening. The seal includes an axially extending ring section having a first end, a second end, an inner surface, and a disk section disposed substantially perpendicular to the ring section inner surface between the ring section first and second ends. The seal conforms to the shaft inner surface to stop oil leakage.

Abstract: An air turbine starter with an improved seal assembly disposed between the turbine and the housing is provided. The seal assembly comprises a face seal, a non-contacting seal axially spaced therefrom to define an air filled annular chamber therebetween and a flow passage having an exit fluidly communicating with said chamber and an inlet fluidly communicating with a source of air.
