Abstract: A portable apparatus (10) providing both substantially automated performance monitoring and audio entertainment features. In a preferred embodiment the apparatus (10) broadly comprises a portable housing (12); an attachment mechanism (14); a GPS component (16); a heart rate monitor component (17); an audio component (18); a user interface (20); a processor (26); and a power supply (30). The housing (12) may include a headset (1112a) wherein the GPS component (16) is located, and a second housing component (1112b) wherein the processor (26) is located, wherein the GPS component (16) communicates with the processor (26) in a wireless manner. The apparatus (10) is adapted to determine a number of laps or a distance, to provide an elapsed time, and to determine a speed.

Abstract: A system and method for correcting a gain and phase imbalance between I and Q channels of a synchronous detector. The method of the invention includes the steps of: a) inputting a signal into the detector and extracting therefrom a received signal and a corresponding image signal; b) inputting the received signal in a first Doppler filter; c) inputting the image signal in a second Doppler filter; d) forming a first discriminant; e) forming a second discriminant; f) computing phase (.phi.) and gain (.rho.) errors from the first and second discriminants; g) calculating first and second correction factors based on the phase and gain errors; and h) using the correction factors to correct the phase and gain imbalance errors.

Abstract: A dental curette or scaler having a finger pad including a generally concave finger surface proximate a working head and complementary contoured to the shape of an extended middle finger urged thereupon. The finger pad is selectively rotatable about and removable from a tapered end closely proximate the working head of the instrument. The finger pad is comprised of a resilient material to adapt to individual finger variations and is textured to provide a comfortable feel and a friction grip to the dental hygienist or dentist. The finger pad is restricted from lateral sliding along a longitudinal axis of the instrument and, further, is sterilizable prior to use. In an alternative embodiment of the invention, the finger pad has a plurality of finger surfaces for receiving a finger in more than one position.

Abstract: In the manufacture of a thin film electroluminescent display panel, patted transparent electrode stripes on a glass substrate are smoothed by:(A) depositing a uniform layer of dielectric material over the entire substrate bearing the patterned transparent electrode stripes,(B) applying a uniform layer of an organic flowable photoresist material over the layer of dielectric,(C) heating the coated substrate to a temperature at which the photoresist layer flows, and(D) etching back through the layers to the transparent electrode.
