Abstract: Sensor systems can be used to measure an analyte concentration. Sensor systems can include a base having a distal side configured to face towards a person's skin. An adhesive can couple the base to the skin. A transcutaneous analyte measurement sensor can be coupled to the base and can be located at least partially in the host. A transmitter can be coupled to the base and can transmit analyte measurement data to a remote device.

Abstract: A dynamic compressor includes an impeller having impeller vanes disposed around a hub, a shroud, and a diffuser having a shroud surface adjacent to the shroud and a hub surface adjacent to the hub, wherein the diffuser is circumferentially disposed around the impeller. The diffuser includes a plurality of diffuser vanes extending from the hub surface to the shroud surface, each having a vane leading edge and a vane trailing edge. The diffuser includes a centrifugal acceleration stabilizer ring formed in the shroud surface located in a vaneless region defined between an impeller trailing edge and the vane leading edge. The centrifugal acceleration stabilizer ring stabilizes the flow of the fluid by changing the circumferentially-flowing high velocity fluid flow exiting the impeller into a radially-flowing high velocity fluid flow before entering the diffuser, improving the efficiency of the dynamic compressor.

Abstract: An automatic transmission fluid change apparatus includes a drain pan and associated holding tank for collecting and retaining used fluid recovered from an automatic transmission. A new fluid reservoir is provided within the apparatus to contain the quantity of new fluid required for a complete change of fluid in the transmission. To accomplish a complete change of fluid in the automatic transmission, the transmission pan and filter are removed and new fluid is pumped from the new fluid reservoir to the transmission orifice to which the outlet tube of the filter is typically coupled. The vehicle engine is simultaneously run at idle speed to circulate the new fluid throughout the transmission, thereby forcing all used fluid out of the transmission for collection and storage in the holding tank.
