Abstract: An implantable medical lead includes a lead body extending from a proximal end to a distal end. The lead body includes an inner insulation layer and an outer insulation layer. The lead further includes a sleeve mechanically supported by the lead body at the distal end of the lead body. The lead further includes an uninsulated conductor coil. The uninsulated conductor coil includes a first portion having a first inner diameter, and a second portion having a second inner diameter and extending distally from the outer insulation layer. The first portion is positioned between the inner insulation layer and the outer insulation layer. The second inner diameter is greater than the first inner diameter. An outer surface of the second portion is exposed.

Abstract: A coin sensor utilizes time-multiplexing of LC oscillators having natural frequencies F1A, F1B, F2, and F3 to produce magnetic fields in three sets of windings. As a coin passes through the coin sensor, the LC oscillators are separately enabled in a sequence to produce a frequency profile for each set of windings. A first winding produces a frequency profile for the facial area of a coin, a second winding produces a frequency profile for a cross-sectional area of a the coin, and a third winding produces a frequency profile for further distinguishing the relative size of a coin. A microcontroller identifies signature points from the frequency profiles and compares the signature points with stored signatures for a multitude of coins and/or tokens.

Abstract: Water dispersible granules suitable for agricultural application are prepared by first preparing absorbent water dispersible granules and then loading biologically active substances into the preformed absorbent granules.

Abstract: A laser distance measuring device includes a semiconductor source, such as a laser diode, that produces a laser beam, preferably in the visible range. A driver selectively drives the semiconductor source at a minimum of two different driving frequencies. A laser beam receiver has a detector that produces an output signal which varies with the intensity of the received laser beam, an amplifier that amplifies the output signal of the detector, and counter means for controllably counting the number of cycles in a clock signal. A beam director selectively directs the laser beam toward an object and receives the reflected laser beam from the object, and directs the laser beam toward the receiver without traveling to the object. A microprocessor controls the driver, the counter, and the beam director.
