Abstract: In an example there is provided circuitry for detecting a type of accessory connected to a first jack plug inserted into a first jack port. The circuitry is configured to determine whether an audio signal is present at the tip or the ring of the first jack plug. If there is an audio signal present at the tip or the ring of the first jack plug, then the circuitry is configured to determine that the type of accessory is a stereo line-in accessory connected to a 3-pole jack plug.

Abstract: A method and apparatus for endpoint detection for the stripping of a particular material, such as photo-resist material, from a substrate surface. A beam of light is projected onto the substrate surface and the fluoresced and/or reflected light intensity at a particular wavelength band is measured by a light detector. The light intensity is converted to a numerical value and transmitted electronically to a control mechanism which determines the proper disposition of the substrate. The control mechanism controls the cessation of the stripping process and may control a substrate-handling device which sequentially transfers substrates to and from a stripping chamber.

Abstract: An apparatus and method for automatically tuning the power and the intensity of light supplied to an illuminated object to some desired values, the apparatus including a light source positionable along at least a first axis with respect to a reflector, a drive assembly for positioning the light source in response to an intensity of light measured by a light meter positioned to sample light reflected from the object along a reflected light path, and a diaphragm having an adjustable aperture for controlling the amount of light supplied to the object. The light source is automatically positioned along the first axis to achieve a maximum intensity of light on the object. The light source may then be automatically positioned along a second axis and a third axis to achieve respective maximum light intensities on the object.

Abstract: A dryer for use in an asphalt plant for heating and drying virgin aggregate and also pre-heating reclaimed asphalt products (RAP). A drying drum cylinder having a burner at one end heats and dries virgin aggregate traveling therethrough. A second cylinder near the burner surrounds the drying drum and creates an annular cavity. RAP is introduced and travels through the annular cavity and exits adjacent the drying drum aggregate exit opening. Heat given off by the drying drum increases the temperature within the annular cavity and heats the RAP traveling therethrough. Heated aggregate and RAP first come in contact with one another after exiting the annular cavity and the drying drum and are, thereafter, delivered to a mixing drum.
