Abstract:
The orientation of a vehicle rear-view mirror carried by a mirror support member is adjusted from inside a vehicle about a horizontal axis by turning a tubular bearing member, to which the mirror support member is hinged, about its axis by rotating a first control member and, independently, about a generally vertical axis defined by the axis of the hinge by moving a push member axially in the passage in the tubular bearing member by rotating a second control member.
Abstract:
A method of navigating a mobile robotic device may include receiving, by a mobile robotic device, a wireless transmission from a transponder associated with an object, where the object is within a range of the mobile robotic device and in response to receiving the notification, altering a navigation course by the mobile robotic device to allow the object to pass the mobile robotic device. The mobile robotic device may be preprogrammed with at least a portion of the navigation course. The method may include resuming the navigation course by the mobile robotic device.
Abstract:
A method and apparatus for measuring an apparent depth (1) of a section of an eye (30) are disclosed. Light is focused to a measurement location (15) proximate or within the eye. The measurement location is scanned through the section and upon passing through first and second refractive index interfaces defining the section, a respective reflected light signal is detected, from which apparent positions of the first and second interfaces may be derived. Preferably, a confocal scanning arrangement is employed. Preferably, the section is the aqueous humor (34) of the eye (30). From changes in its refractive index (n) corresponding changes in glucose concentration in the aqueous humor and, in turn, in the bloodstream of a patient may be derived, offering a non-invasive monitoring means for diabetic patients. The apparatus may be a hand-held device, employing microelectromechanical systems. The radius of curvature (R) of a curved section, such as a cornea (32) or ocular lens (36), may also be measured to determine refractive errors of the eye.
Abstract:
A system and method for treating contaminated wastewater is provided. The system and method may be used to treat wastewater such as hydraulic fracturing flowback water, which is contaminated with guar gum, similar gelling agents, or other biological polymers. The contaminated wastewater is pressurized and heated and then allowed to spend a residence time in a vessel. The process may be a continuous or a batch process. The exposure to a combination of heat and pressure causes the high molecular weight guar molecules to break down into simple sugars and other smaller, relatively low molecular weight compounds, thereby decreasing the viscosity of the fluid. Once the viscosity is reduced, the flowback water can then be treated for other contaminants using conventional treatment technologies and reused in fracking operations.
Abstract:
Devices and techniques for indicating packet processing hints are described herein. A device may receive a data packet. The device may extract a match-action attribute from the data packet that specifies an action to be applied to the data packet. The device may generate a hint field based on the match-action attribute. The hint field may include information to be used for handling the data packet. Other embodiments are also described.

Abstract:
In a method of operating an internal combustion engine, a nitrogen-containing detergent composition is introduced into a combustion chamber of the engine wherein the detergent composition can improve the performance of both a fuel composition and a lubricating oil of the engine. The detergent composition contains (A) a reaction product of a hydrocarbyl-substituted acylating agent and an amine, (B) a hydrocarbyl-substituted amine, (C) a Mannich reaction product, (D) a high molecular weight polyetheramine, or (E) a mixture thereof.
