Abstract: A dual-wall fitting includes an outer fitting member and a fitting insert. The fitting insert may be slideably placed within the outer fitting member. The outer fitting member has an inner surface and a channel surface. The inner surface defines an upper channel and the channel surface defines a first leakage channel that extends from an exterior of the outer fitting member to the upper channel. The fitting insert has an outer insert surface that defines a groove. When the fitting insert is slideably placed within the outer fitting member, the inner surface of the outer fitting member and the groove defined by the fitting insert define a second leakage channel. The first leakage channel is in fluid communication with the second leakage channel.

Abstract: The invention provides a tool for improved self inspection of surface skin abnormalities of the human back. The Back-Aid device also enables one to treat complexion issues, precisely apply medicines or sunscreen, and monitor would healing by themselves. The device consists of a computer web-cam strategically mounted to a handle of rigid material which provides for easy manipulation over desired areas of the back. The images captured by the web-cam are displayed on a computer screen in which photo's and video's of images can be e-mailed to a doctor of the operators choice.

Abstract: An engine includes a housing having a combustion chamber. The engine may also include a fuel injector for supplying fuel directly or indirectly to the combustion chamber. Additionally, the engine may include an engine-lubricant-supply system operable to discharge engine lubricant onto the fuel injector.

Abstract: A control system for controlling a device, the device having at least two functional elements, each functional element being controlled by a control signal, is disclosed in the present disclosure. The control system may include detecting means operatively connected to the device and configured to monitor the operation of the device, and to generate a signal indicative of an operating condition of the device. The control system may also include a control module operatively connected to the at least two functional elements and the detecting means, and configured to switch the two control signals applied to the respective functional elements in response to the signal generated by the detecting means.

Abstract: A fluid system for an engine is disclosed. The fluid system has a manifold with a plurality ports, and a retention device configured to constrain the manifold relative to the engine in only a single translational direction. The fluid system also has a plurality of tubes configured to communicate fluid from the ports with the engine and to constrain the manifold in the remaining translational directions.
