20080297769 | Through-container optical evaluation system - An apparatus, and method of its use, to determine a characteristic of a fluid sample contained inside a closed container. The ratio of intensity for detected radiation (e.g., light), subsequent to its transmission through the container's walls and fluid in the container, at each of a reference wavelength and a measurement wavelength is compared to a predetermined value to make a determination of the fluid's characteristic. Desirably, the wavelengths are applied to the same location on the container to minimize a source of signal error. The reference wavelength is selected for its substantial lack of attenuation when transmitted through a known fluid composition. The measurement wavelength is selected for its predictive interaction (e.g., absorption) with the fluid. | 12-04-2008 |
20090249900 | GIMBAL - A gimbal is described and which includes a fixed base member defining an axis of rotation; a second member concentrically oriented relative to the axis of rotation; a linear actuator oriented in immediate, adjoining force transmitting relation relative to the base member or to the second member, and which applies force along a linear axis which is tangential to the axis of rotation so as to cause the second member to rotate coaxially relative to the fixed base member; and an object of interest mounted to the second member such that the object of interest is selectively moved relative to the base member about the axis of rotation. | 10-08-2009 |
20100116588 | UNIVERSAL BELAY DEVICE - The present invention provides a universal belay device for providing safety to mountain and rock climbers. The belay device allows a belayer to selectively operate the device in any of a plurality of modes. In an auto-locking mode, a fall by a climber automatically stops the rope without requiring the belayer manually apply any holding or stopping force. In a frictional mode, a fall by a climber is stopped by the belayer applying a minimal amount of pressure. The belay device includes a housing in which a rope pin and cam are contained. The cam is rotable to a first position which allows the rope pin to frictionally secure the rope against the housing and stop the rope. The cam is rotable to a second position which substantially prevents the rope pin from fully securing the rope and requires the user to apply a stopping force to stop the rope. | 05-13-2010 |
20100187203 | MULTI-WIRE ELECTRON DISCHARGE MACHINE - A multi-wire electron discharge machine includes a first wire electrode for creating an electrical discharge between the first electrode wire and a semiconductor ingot, a second wire electrode for creating an electrical discharge between the second electrode wire and the semiconductor ingot, and a wire guide for maintaining the first wire electrode in a spaced apart and generally parallel orientation with respect to the second wire electrode across a semiconductor ingot slicing area. | 07-29-2010 |
20100199909 | SYSTEMS AND METHODS FOR RECYCLING SEMICONDUCTOR MATERIAL REMOVED FROM A RAW SEMICONDUCTOR BOULE - Methods of recycling excess semiconductor material removed from an unshaped semiconductor boule are disclosed. Excess semiconductor material is cut from an semiconductor unshaped boule thereby generating a shaped semiconductor boule. The excess semiconductor material is removed in the form of large pieces that can easily be cleaned and retrieved for reuse. | 08-12-2010 |
