Abstract: A mopping device includes a mopping portion, a fluid release device for releasing fluid to at least one of a surface to be mopped and the mopping portion, a handle configured to be gripped by a user to control the mopping portion, and a reservoir for storing fluid. The reservoir can include an expandable bladder. The reservoir also can be configured such that air need not be evacuated from the reservoir during tilling of the reservoir. The mopping device also can be part of a mopping system, in which a refill reservoir is provided to refill the reservoir of the mopping device.

Abstract: A system for correcting infrared (IR) radiances includes an imager for receiving IR radiances and outputting intensity data corresponding to pixels in the imager. Also included is a stray light estimator for receiving the intensity data and estimating stray light in the intensity data. The stray light estimator includes a Bessel filter for low pass filtering the estimated stray light and providing corrected intensity data as an output to a user. The Bessel filter is an n-pole recursive digital filter, which is expressed as a ratio between (a) an (n?1) order polynomial of a complex number and (b) an n order polynomial of a complex number, where n is a positive integer. The Bessel filter includes an infinite response curve, in which the response curve monotonically decreases in amplitude as a function of frequency per pixels.

Abstract: A system for calibrating a broadband detector includes a first narrowband telescope for viewing a celestial body, and an earth viewing telescope. The broadband detector is selectively coupled to the first narrowband telescope or the earth viewing telescope. A first narrowband filter is selectively inserted in an optical path of the first narrowband telescope, or the earth viewing telescope. A processor is configured to calibrate the broadband detector based on viewing the celestial body with the first narrowband telescope or the earth viewing telescope, and selectively inserting the first narrowband filter in the optical path. The first narrowband telescope includes a first narrowband filter inside its optical train. The first narrowband filter, which is selectively inserted in the optical path, is spectrally similar to the first narrowband filter inside the optical train of the first narrowband telescope.

Abstract: A system assesses a column of gas in an atmosphere. The system includes an optical transmitter for transmitting (a) an online signal tuned to an online wavelength of gas, (b) an offline signal tuned to an offline wavelength of the gas, and (c) an optical signal for providing altimetry data. A modulator is included for modulating the online signal with a first stepped chirp waveform and modulating the offline signal with a second stepped chirp waveform. A processor assesses the column of gas, after receiving a returned online signal, a returned offline signal and a returned optical signal. A lock-in amplifier is included for (a) multiplying a returned signal with the first stepped chirp waveform to obtain a detected online signal, and (b) multiplying the returned signal with the second stepped chirp waveform to obtain a detected offline signal. The processor is configured to remove ground reflections from the optical signal to obtain scattered noise, and assess the column of gas based on the scattered noise.

Abstract: A method for calibrating a spectrometer, while orbiting a celestial body, includes the steps of: (a) obtaining an estimate of radiance emanating from the celestial body; (b) raster scanning the celestial body using the spectrometer; (c) measuring filtered radiance of the celestial body based on step (b); and (d) determining gain of the spectrometer using steps (a) and (c). A calibrated spectrometer of the present invention is based on the determined gain of step (d). The method includes the step of: (e) raster scanning another celestial body to determine the albedo radiance of the other celestial body, after determining gain of the spectrometer in step (d). The celestial body may be the moon and the other celestial body may be the Earth.

Abstract: A system for calibrating a spectrometer includes wide field-of-view (WFOV) optics providing a first light path to a WFOV spectrometer, and narrow field-of-view (NFOV) optics providing a second light path to a NFOV spectrometer. A de-focusing optic is selectively positioned in the first or second light paths. A scan controller selectively controls the WFOV or NFOV optics to scan a celestial body. A processor is configured to calibrate the de-focusing optic, while the WFOV optics scan the celestial body. First, the WFOV optics scan the celestial body without the de-focusing optic positioned in the first light path. Second, the WFOV optics scan the celestial body with the de-focusing optic positioned in the first light path. Next, the processor calibrates the NFOV spectrometer, while the NFOV optics and the de-focusing optic scan the celestial body. After the NFOV spectrometer is calibrated, the NFOV spectrometer may be used to measure the albedo of the earth.

Abstract: A door opener for opening a door having an external surface comprises a screw mounted for rotary motion and a carriage mounted on the screw such that rotation of the screw causes motion of the carriage along the screw. A motor rotates the screw. An actuator arm has a first end and a second end, where the actuator arm is operatively connected to the carriage such that movement of the carriage causes the actuator arm to move between a retracted position where the door is closed and an extended position where the door is open. The first end of the actuator arm is in contact with but not connected to the external surface of the door such that the first end of the actuator arm rides over the external surface of the door.
