A frame assembly for retaining a window panel in an aperture in a door. The frame assembly having a first frame member having a first outer face, a first window engaging surface, and a first door engaging surface, a second frame member having a second outer face, a second window engaging surface, and a second door engaging surface, a third frame member adapted to attach to the first outer face of the first frame member by a plurality of first screwless connectors, and a fourth frame member adapted to attach to the second outer face of the second frame member by a plurality of second screwless connectors. The first frame member is secured to the second frame member such that the window panel is held in the aperture between the first window engaging surface and the second window engaging surface and the door is held between the first door engaging surface and the second door engaging surface.

Door lite frame assembly

An apparatus is provided that includes a plurality of reflectors arranged over an area, and a plurality of transceivers. A first of the transceivers is configured to transmit radiation at each of the plurality of reflectors at a first wavelength and a second wavelength, and receive radiation reflected from each of the plurality of reflectors. A second of the plurality of transceivers is configured to transmit radiation at each of the plurality of reflectors at a third wavelength and a fourth wavelength and receive radiation reflected from each of the plurality of reflectors. The apparatus includes a processor configured to calculate a change in concentration of a gas within the area between a first time and a second time based upon signals received from the transceivers.

Real time spatial mapping of atmospheric gas distributions

Remote absorption spectroscopy uses coded electromagnetic transmission directed through a medium under investigation to one or more remote receivers. The coded transmission includes at least one wavelength coincident with an absorption band of interest and one wavelength in an off-line band and a predefined relationship between spectral components in and outside the absorption band is controlled. The relationship between spectral components may be evaluated at the receiver to determine whether deviation thereof from the controlled relationship at the transmitter exists at the receiver. The deviation of the received optical signal from the prescribed relationship is processed to indicate the absorption of the radiation in the absorption band.

Remote absorption spectroscopy by coded transmission

A lock-in ratio measurement system including a plurality of channels. Each of the channels generates and transmits a radiation signal modulated by a sequence of tones. The sequence of tones for each channel being unique in time to that respective channel. Each respective modulated signal is absorbed/reflected from a target or medium and received. Each channel computes a lock-in value based on the received modulation signal. The lock-in values are used to compute ratios between the channels for characterizing a target or medium.

Tone hopped lock-in system

Entry systems that minimize water infiltration due to a wind driven rain. In one embodiment, the entry system includes a corner pad that includes an upper portion that seals against the weather strip when the door is closed and a lower portion that is spaced apart from the weather strip to form a gap between the lower portion and the weather strip. The lower portion seals against the door when the door is closed.
