    摘要: A method for detecting the concentration of one or more gas species by using infrared radiation emitted from one or more sources into a sample cell which is a hollow waveguide with multiple bends collectively greater than 180 degrees in three dimensions, the infrared radiation being quasi-focused into a beam with an angle of incidence between greater than approximately 0° and approximately 10° relative to a longitudinal axis of a first linear segment of the sample cell proximate the source, then detecting two or more signals in which one of the signals is used to compensate for water vapor. The methods can detect gas concentrations down to 1 ppm or less.

    摘要: A biometric method and system for personal authentication using sequences of partial fingerprint signatures provides a high security capability to various processes requiring positive identification of individuals. This approach is further enhanced by employing a frequency domain technique for calculating a Similarity Index of the partial fingerprint signatures. In a baseline usage, the sequential partial fingerprint sequence techniques augments sentinel systems for gaining access to restricted areas, and when used in combination with financial cards, offer a unique and greatly simplified means for authenticating or identifying individuals. A highly automated technique initially obtains a reference set of linear partial fingerprint signatures which serve as reference data against which later proffered candidate data in the form of at least two linear partial fingerprint signatures are compared for authentication. The particular two candidate signatures used and the sequence in which they are submitted are selected with the user's consent and serve as a PIN-like unique personal code. In an advanced embodiment, a pair of proximity sensors located along each of the linear tracks used for developing the linear partial signatures produce finger sensing signals which compensate for finger movement speeds and hence significantly improves the calculated Similarity Index values. The use of only partial fingerprint data greatly allays the concerns of widespread fingerprint dissemination by many individuals.

In a baseline usage, the sequential partial fingerprint sequence techniques augments sentinel systems for gaining access to restricted areas, and when used in combination with financial cards, offer a unique and greatly simplified means for authenticating or identifying individuals. A highly automated technique initially obtains four (illustratively) linear partial fingerprint signatures which serve as reference data against which later proffered candidate data in the form of at least two linear partial fingerprint signatures are compared for authentication. The particular two candidate signatures used and the sequence in which they are submitted are selected with the user's consent and serve as a PIN-like unique personal code. In an advanced embodiment, the same two candidate signatures in the chosen sequence are processed in a unique FFT/DFT process to produce a highly reliable Similarity Index to authenticate or verify the identity of individuals. The use of only partial fingerprint data greatly allays the concerns of widespread fingerprint dissemination by many individuals.

    摘要: A miniaturized NDIR gas sensor is manufactured using semiconductor micromachining techniques from a semiconductor material such as Si or GaAs. The NDIR gas sensor comprises an optical waveguide, a light source at one end of the waveguide, at least one light detector at the end of the waveguide opposite the light source, a diffusion type gas sample chamber formed within the waveguide and interposed in the optical path between the light source and light detector so that the light source and light detector are thermally isolated from the gas sample, and a separate bandpass filter interposed between the light source and each light detector. Because the NDIR sensor is fabricated out of a semiconductor material, the source driver and signal processing electronics may be added directly to the sensor using integrated circuit fabrication techniques. Particles and smoke and dust may be kept out of the sample chamber by application of a gas permeable membrane over apertures in the sample chamber walls.

    摘要: A compact low-cost fire detector responds quickly by detecting an increase in the concentration of carbon dioxide gas in the ambient air. The detector also calculates the rate of build-up of carbon dioxide. The detector avoids the use of moving parts by employing a differential temperature black body source of infrared radiation in conjunction with a dual pass band filter. One of the pass bands is located at the 4.26 micron absorption band of carbon dioxide gas and the other pass band is located at 2.20 microns at which none of the atmospheric gases has an absorption band. The latter channel serves as a reference and renders the detector immune to false alarms caused by dust or smoke particles in the air or due to deterioration of certain components. The fire detector makes use of a sample chamber that consists of a serpentine passage in a block of material, the walls of the serpentine passsage being highly reflective so as to act as a light pipe.

    摘要: A multi-component non-dispersive gas analyzer of a type typically used to measure the concentrations of gases present in automotive emissions and in breath analyzers has no moving parts and employs electrically operated means for effectively inserting and removing a reference cell from the optical path and for selecting a particular filter to determine momentarily the wavelengths of radiation being examined. The means for accomplishing these ends include a substrate on which a layer of vanadium dioxide is deposited. The layer is a good reflector at temperatures greater than 67.degree. C. and reflects only slightly at lower temperatures. The layer is alternately heated by an electrical current and is then allowed to cool to provide the desired optical switching action. This electrically-controlled selectively reflective layer is then used in conjunction with the reference cell and with an array of filters to implement the necessary switching and selection of the components.

    摘要: A method and apparatus are described for detecting the presence and amount of elemental oxygen in a sample cell. The intensity of extreme ultraviolet light passing through the sample cell at a wavelength band overlapping at least one of the Schumann-Runge absorption lines of oxygen is detected and compared with a predetermined non-absorbed condition of the ultraviolet light. The non-absorbed condition may be achieved by narrowing the wavelength band such that the band does not overlap the Schumann-Runge absorption line, or may be achieved by detecting the ultraviolet light passing through a reference cell. Also described is a novel ultraviolet source in which a cold zone captures neutral atoms of the emission gas to reduce the affect of resonance absorption of emitted ultraviolet light by such neutral atoms.

    摘要: A card game with similarity to mahjongg is played by two to four players with a deck of 52 cards containing five wild cards, three suits with nine numbers in sequence and five groups of four identical cards in which a series of hands are played in which each player progressively takes a turn starting as the dealer and each hand is scored to come up with a total score and the total scores for all the hands in the series of hands are added up for settlement. Each hand is begun by dealing each player seven cards and using the remainder of the deck as a draw pile. A drawing player (other than the dealer whose discard starts a discard pile) takes one of three steps. First, if the drawing player has four of the same cards, the player can declare a gong operation, draw another card, and then proceed again with another gong operation or one of the following two steps. Second, the player can end the hand by declaring a winning hand containing a pair of identical cards and two triplets; the triplets can either be a pong group of three identical cards or a tsee sequence of three consecutive numbers in a single suit of cards. Third, the player can discard a card face up on the draw pile. The play follows sequentially unless another player out of sequence invokes a rule for picking up the top card in the discard pile.

    摘要: NDIR gas sensing methodology is advanced which renders the output of an NDIR gas sensor, when implemented with this new methodology, to remain stable or drift-free over time. Furthermore, the output of such a sensor will also be independent of the temperature of an environ wherein the sensor is in physical contact. This method utilizes the same narrow band-pass spectral filter for the detection of the gas of interest for both the signal and the reference channels. By so doing, the two channels always receive radiation of the same spectral content from the infrared source of the sensor convoluted with that from any external elements exposed to the sensor. While the same sample chamber through which the gas of interest to be detected flows is shared by the two channels, the detector package for the reference channel is hermetically sealed with 100% of the gas to be detected instead of 100% N2 as for the signal detector. In so doing, the reference channel is rendered almost completely “blind” to the presence or absence of the gas of interest flowing in the common sample chamber thereby creating an absorption bias or difference between the two channels enabling the concentration of the gas of interest to be detected by ratioing the outputs of the two channels via calibration.
