Abstract: A case for a portable electronic device and a keyboard includes a first cover portion, an engagement member secured to the first cover portion and configured to support the portable electronic device, a second cover portion configured to support the keyboard, and a spine portion connecting the first cover portion to the second cover portion. The spine portion allows movement of the first cover portion relative to the second cover portion so that the case is positionable in a closed position and in an operating position. The case also includes a rigid spine component coupled to the second cover portion adjacent the spine portion. The rigid spine component includes a groove configured to receive a portion of at least one of the engagement member and the portable electronic device when the case is in the operating position.

Abstract: A transition duct (30) for a gas turbine engine (2) having improved cooling and reduced stress levels. The transition duct may be formed of two panels ((36, 38) joined together with welds (40) disposed remote from the bent corner regions (34) of the panels. Cooling channels (32) extending longitudinally in the direction of flow of the hot combustion gas carried by the duct are formed within each panel, including the corner regions. Because the entire annular width (W) of the transition duct is cooled, the gap (G) separating adjacent ducts around the inlet to the turbine (4) may be reduced when compared to prior art designs. Two-panel construction with welds remote from the corner regions is facilitated by maintaining the minimum bend radius in the corners (R2) and in the direction of flow (R4) to be greater than in prior art designs.

Abstract: Aspects of the invention relate to a system for supporting the exit end of a transition duct. The system includes a plurality of support ring segments that collectively form an annular support ring assembly. Each support ring segment can have an outer span and an inner span that are joined by a central column. Lateral openings can be defined on each side of the central column. The lateral openings of two adjacent support ring segments can cooperate to form an opening. An outlet region of a transition duct can be inserted into a respective opening and engage seals provided along the opening. The interface of adjacent ring segments occurs along an imaginary line across the outlet of the common transition duct body. Each support ring segment can be attached to the transition duct as well as to a fixed portion of the engine such as the turbine stationary support structure.

Abstract: A seat for supporting the pelvis of the user in a correct physiological position substantially corresponding to the pelvic standing position. The seat has a dished gluteal position (16) which extends to the rear of the seat and a seat back (11) with a substantially convex upper portion (13) and a concave lower portion (12) with the distance between the junction (21) of the two and the lowest point (22) of the dished gluteal portion (16) substantially corresponding to the average dimension between the posterior superior spine of the ilia P and the ischial tuberosities (site bones) of an adult person.
