A brake coupled to the front wheel provides braking rotation of the front wheel and a controller controls operation of the brake to generate a desired braking force in a direction determined to adjust a vehicle direction.

Abstract: A camera for capturing an image of an object, for example an eye. The camera has at least two light sources and an image-sensing system having two image sensors. A multiple branch optical system transmits outgoing light from the light sources to the object, and transmits incoming light from the object to the image-sensing system. The multiple branch optical system includes an autofocusing element such as a variable power optical element that varies the focus of the incoming light. There is also an image display. There is a controller that controls the operation of the light sources, controls acquisition of images by the image-sensing system, and controls the display of images on the image display. The controller activates an autofocus light source and uses the resulting captured image to automatically adjust the image exposure parameters.

Abstract: A process for preparing a gas permeable flexible graphite sheet is presented. The process includes providing graphite flakes; admixing the graphite flakes with a sacrificial additive to form a graphite mixture; compressing the graphite mixture into a sheet having sacrificial additive dispersed therethrough; and treating the sheet to at least partially remove the sacrificial additive to form a permeable flexible graphite sheet.

Abstract: An oligomerization process in which hydrocarbon feedstocks are contacted with a hydrotreating catalyst in the absence of hydrogen and in the liquid phase. The catalyst is a heterogeneous catalyst selected from supported reduced metals, metals oxides, metal sulfides and combinations thereof. Preferred catalysts include mixed nickel and molybdenum oxides or mixed cobalt and molybdenum oxides. The process also oligomerizes sulfur compounds so that sulfur containing feedstocks can be treated without deactivating the catalysts.

Abstract: An improved method enables preparation of articles for a variety of applications, including embossing or otherwise shaping to form a variety of articles. A plurality of thin, preferably resin-impregnated, flexible graphite sheets are arranged to form zones in a composite material having a graded density or other characteristic. Variation of properties between zones in the stock material formed is useful for achieving a desired set of properties in the formation of articles such as those useful in electrochemical fuel cells and double-layer capacitors.

Abstract: An intraocular lens is provided that includes an optic body having anterior and posterior walls, a chamber, and optically transmissive primary and secondary fluids, and method for making and using the same. One of the fluids is a gas. The secondary fluid is substantially immiscible with the primary fluid and has a different density and a different refractive index than the primary fluid. The primary fluid is present in a sufficient amount that orienting optical body optical axis horizontally for far vision positions the optical axis through the primary fluid, thereby immersing the anterior and posterior optical centers in the primary fluid. The secondary fluid is contained in the optic body in a sufficient amount that orienting the optical axis over a range of effective downward angles relative to the horizontal for near vision positions the optical axis to extend through the primary fluid and the secondary fluid, thus changing the focus of the intraocular lens.
