Patent number: 6147761Abstract: A sensor for measuring reflective, transmissive, or self-luminous samples, comprises a plurality of light sources, where each of the light sources emit light of a substantially different wavelength band spaced in the visible spectrum; a reference channel photodetector; a sample channel photodetector; an optical cap adapted to direct a first portion of the light emitted by each of the light sources to the reference channel photodetector, a reflector cone for directing a second portion of the light emitted by each of the light sources to the sample; and a receptor piece for directing the diffuse portion of the light reflected from the sample to the sample channel photodetector. Preferably, the reference channel and sample channel photodetectors are identical devices and are mounted back-to-back to share environmental characteristics, and in turn, minimize the variation between their respective responses.Type: GrantFiled: April 14, 1998Date of Patent: November 14, 2000Assignee: Color Savvy Systems LimitedInventors: Eric Walowit, Ronald J.

Patent number: 5963333Abstract: A hand-manipulatable device includes a sensor for gathering reflective, densitometric, spectrophotometric, colorimetric, self-luminous or radiometric readings from a sample surface. The device includes a housing having a substantially flat bottom surface and a top surface contoured to fit comfortably in the fingers and palm of the human hand. The housing also includes area on its top surface for seating an index finger of the human hand. Positioned within this area is a pressure-activated switch that is operatively coupled to the sensor circuitry for performing the readings. Preferably, the sensor is mounted into the device such that the focal aperture of the sensor is in axial alignment with the pressure-activated switch. Accordingly, a user will be able to use the device to "point" with his or her index finger to an area of the sample surface, and will then simply press the switch to initiate the readings, using the same index finger.Type: GrantFiled: September 4, 1997Date of Patent: October 5, 1999Assignee: Color Savvy Systems LimitedInventors: Eric Walowit, Ronald J.
