Title: Anordning for aspirasjon av fluider
Inventor: CONSTON STANLEY R
IPC: A61F9/007
Filed: 2011-08-22
Abstract: Kirurgiske anordninger er tilveiebrakt for aspirasjon av det subretinale fluidet (SRF) i øyet i en retinal løsrivelse som muliggjør re-apposisjon av den sensoriske retina til det underliggende RPE. Anordningen er tilkoplet en vakuumkilde innført i det bakre kammeret gjennom en sklerotomiåpning og plassert mot det løsrevede retitinale vevet. Anordningen trekker på og griper overflatene av den sensoriske retina, som fører til at en mikronål gjennomborer vevet. Siden den sensoriske retina gripes og holdes på plass av vakuumet, dannes en beskyttet lomme, og vevet forhindres fra å folde seg oppå seg selv og okkludering av mikronålspissen.

Title: Apparatus for automatically controlling operation of a clutch, in particular for determining the initial engagement point for an automatic clutch controller as well as method for automatically controlling operation of a clutch, in particular for determining its position corresponding to transmission of initial torque in an automatic clutch controller
Inventor: LIU CHIA-HSIANG
IPC: B60W30/19
Filed: 1992-12-17
Abstract: This invention provides automatic and reliable determination of the touch point of a clutch controlled by an automatic clutch actuation controller. This invention determines the touch point while idling the engine, with the transmission in neutral and an inertial brake applied. The clutch actuation controller engages the clutch so that the measured transmission input speed matches a reference speed signal preferably between 40% and 60% of the idle speed. This reliably provides the degree of clutch engagement at a small torque matching the braking torque. When the transmission input speed is within a predetermined amount of the reference speed signal, such as 4%, this invention determines the clutch touch point corresponding to the degree of clutch engagement. This degree of clutch engagement may be a clutch position signal or a clutch pressure signal produced by an existing sensor used in the automatic clutch control. If no measured clutch engagement signal is available, this degree of clutch engagement may be the clutch engagement signal used to control the degree of clutch engagement. The touch point is set as the difference between this degree of clutch engagement for the small torque and a clutch touch point offset. <IMAGE>
