Abstract: An optical magnetic field sensor which can precisely measure a magnetic field strength without measurement errors caused by temperature change is provided.  It comprises a light source, a polarizer, a Faraday element, an analyzer, a first light beam-receiving element, a first calculation circuit, a second light beam-receiving element, a second calculation circuit, and a third calculation circuit.  The light beam emitted from the light source is passed through the polarizer, the Faraday element and the analyzer in sequence.          An S polarized light beam after passing through the analyzer is passed through the first light beam-receiving element and an output signal therefrom is calculated in the first calculation circuit.  A P polarized light beam after passing through the analyzer is passed through the second light beam-receiving element and an output signal therefrom is calculated in the second calculation circuit.  The third calculation circuit is supplied with an output V11 from the first calculation circuit and an output V22 from the second calculation circuit to obtain an output V3 based on the equation V3=1/(.alpha./V11+.beta./V22) when V11~V22 are positive values or from the equation V3=1/(.alpha./V11-.beta./V22) when V11~V22 are negative values with the understanding that .alpha. and .beta. are constants and .alpha.+.beta.=1.  A magnetic field strength value is obtained from the output V3 of the third calculation circuit.

Filed: 1993-04-29
Abstract: A method and apparatus for classifying articles according to their color, wherein a first pair of wavelengths is selected on a plurality of light reflection curves in terms of a reflected light wavelength spectrum. An article to be inspected is illuminated with light comprising the first pair of wavelengths and light reflected therefrom is measured to detect light reflection values corresponding to this first pair or wavelengths. A primary signal is produced, which represents either a difference between or a ratio of the detected light reflection values, this signal being indicative of the color of the inspected article. At least one secondary wavelength is selected on the reflected light wavelength spectrum, and the inspected article is illuminated with light comprising this secondary wavelength and light reflected therefrom is measured to produce a secondary signal which is further indicative of the color of the inspected article. A computer provides a classification frame comprising a first pattern consisting of a first and second crossing set of lines respectively defined by mathematical analysis, this classification frame defining a plurality of color classes. The computer classifies the inspected article in one of the plurality of color classes defined by the frame whenever the primary and secondary signals comply with a specific condition. The computer rejects the inspected article whenever the primary and secondary signals do not comply with this specific condition.

Title: Ringmaster
Inventor: HOOPER WILLIAM T E
IPC: H04M19/04
Filed: 1993-05-25
Abstract: ABSTRACT: Telephone handsets alert their owner/operators to the presence of an incoming telephone call by producing a distinctive sound commonly referred to as the ring. The tonality of this ring is typically engineered by the handset's manufacturer, on a model by model basis, to be a single, specific sound. The ring's duration, however, is fixed by industry practice to approximately two seconds in length. In this invention, the ring is recordable and programmable, both in its tonality and its duration, by the owner/operator, and many such rings can be recorded and maintained at any given time by the invention in its memory bank, for eventual play back, when an incoming telephone call is detected. Furthermore, any ring in the invention's memory bank may be expressly assigned to only play back when the incoming telephone call is determined to have originated from a specific caller's telephone number. Additionally, any ring in the invention's memory bank may also be transmitted by the invention to the calling party once the owner/operator has responded to the incoming telephone call by placing the handset in an off-hook condition.
