The present invention is directed to improved designs and methods for improving engine fuel efficiency by providing two-stage engine variable compression in running engines using connecting rod force reversals to rotate eccentric bushings to change the connecting rod length. Compression ratio changes are initiated by shifting a block-mounted cam such that it engages and flips a bi-stable toggle on the connecting rod. The clutch mechanism latches the eccentric at the eccentric rotation end point, whereupon the connecting rod acts as a rigid rod. The invention includes novel configurations of the lubricated journal bearing between the connecting rod and the eccentric that modify the squeeze film bearing effects and resulting friction. These configurations reduce the peak eccentric torque carried by the clutch mechanism while facilitating eccentric rotation at lower torque.

An apparatus for ejecting a flying body such as a payload recovery container from a spacecraft includes a first ring to be releasably engaged with the flying body, a second ring to be secured to the spacecraft, and tension cables extending between and interconnecting the two rings. Cable winding devices mounted on at least one of the rings are spring-biased to wind-up the cables. The flying body is inserted through the open inner diameter of the second ring, and the first ring is separated from and rotated relative to the second ring, so that the cables extend helically along the outer circumference of the flying body. Holding and guide elements on the second ring hold and guide the flying body. When the holding elements are released, the cables are retracted by the cable winding devices, whereby the flying body is rotated and translationally ejected through the second ring.

The device employs a plurality of coefficients recorded in image data to detect whether edges are included per block, and determines as the blur level the proportion of edges, among the detected edges, in which the edge width is over a certain threshold. The device also determines, per block, coordinates composed of a first coefficient value representing frequency components in a first direction in the blocks and a second coefficient value representing frequency components in a second direction perpendicular to the first direction, and calculates the extent of bias in the distribution of the coordinates as the ellipticity. The device determines whether or not blurring has been produced by camera shake in an image based on the relationship between the blur level and ellipticity which have thus been determined.
