Abstract: Method for broadcasting a magnetic stripe data packet from an electronic card by measuring a swipe speed of the electronic card past a magnetic reader head during a swipe of the electronic card past the magnetic reader head and then adjusting a broadcast signal containing the magnetic stripe data packet according to the measured swipe speed so that the magnetic stripe data packet in the broadcast signal is read by the magnetic reader head during said swipe. The swipe speed is measured by either an active speed sensor or a passive pressure/force speed sensor such as a quantum tunneling composite.

Abstract: A method for communicating with a magnetic stripe reader in which an electronic apparatus is activated from an off state to a reduced power mode, a magnetic stripe reader is detected, then the apparatus is activated from the reduced power mode to a full power mode and it broadcasts a signal that contains a transaction specific data packet that is read by the magnetic read head.

Abstract: A direct view camera with a direct view lens is mounted to a support to obtain a direct view camera shot while a reflected view camera with a reflected view lens is mounted to the support to obtain a reflected view camera shot without use of a beamsplitter. Interaxial spacing between the direct view and reflected view cameras does not cause an overlap between a direct view active optical area of the beamsplitter that would be used by the direct view lens and a reflected view active optical area of the beamsplitter that would be used by the reflected view lens. A reflective planar mirror is positioned to reflect light from a surface of the reflective planar mirror to the reflected view lens while a transparent planar glass is positioned to allow light to pass substantially perpendicularly through the transparent planar glass to the direct view lens.

Abstract: The construct of a specially designed air sampler and its function in order to carry out the Effortless Recalibration (ERB) procedure to an Absorption Biased (AB) designed NDIR gas sensor with the use of a Calibration Master is described.

Abstract: Two detectors of the same kind, each having an identical neutral band-pass filter to the target gas, are installed next to Signal channel and Reference channel detectors as pairs in an AB designed NDIR gas sensor layout, which are called Standard Signal channel detector and Standard Reference channel detector. “Standard” GAMMA is the ratio of Standard signal channel detector output over that of Standard Reference channel detector. “Standard” GAMMA is independent of the measurement Physics of NDIR gas sensors, is dependent only upon the performance characteristics of the sensor component and is also independent of the presence of any amount of target gas in the sample chamber. Consequently, “Standard” GAMMA can be used to proportionally correct and update GAMMA of the sensor as its components age over time thereby rendering such an AB designed NDIR gas sensor self-commissioning or staying accurate over time after initial calibration.

Abstract: Multiple secure transactions are provided through use of a method that uses customer one-time unique purchase order numbers (“Coupons”) generated by an algorithm that uses a permutated user key and a user insertion key as input variables. A user key (such as a Personal Identification Number, or “PIN”) is combined with a permutation variable that is correlated with a customer sequence number to create the permutated user key. A random number generator is used to generate the user insertion key correlated with the customer sequence number. The algorithm can insert the permutated user key into a user account number through use of the user insertion key. A Coupon is validated by confirming that it is contained in a set of money source Coupons generated by a money source using the user key and a random number generator that is synchronized with the random number used to generate Coupons.

Abstract: A re-calibration method for a dual-beam NDIR gas sensor uses a calibration curve based upon a combination of physics and sensor measurement components of the sensor to calculate sample gas concentration, then determines a second gas concentration measurement by a secondary gas standard which is used with a reversed calibration curve algorithm to adjust the sensor measurement component. The calibration curve is based upon a gamma ratio (“G”) that has been normalized by G when no sample gas is present in the sample chamber (“G0”), G being a ratio of a signal channel output (“VS”) of the sensor divided by a reference channel output (“VR”) of the sensor. The concentration (“P”) of sample gas in the sensor is calculated through use of the calibration curve by a gas detection equation of P=F(x)=F(y/G0), where x is a normalized ratio of VS/VR and y is G.

Abstract: An NDIR gas sensor takes advantage of a conventional packaging embodiment commonly used to house detectors of all kinds comprising a can, header and a dish sample chamber all welded together to form a single detector unit. The can forms the top, a hollowed out header body forms the middle and a custom dish sample chamber forms the bottom of a completely functioning NDIR gas sensor. Whereas the header body not only accommodates all the optoelectronic and optical parts on its top surface providing the required signal processing functions for the gas sensor, part of its body is excavated below to accommodate a custom dish sample chamber in communication with the gas outside whose concentration level is to be measured. A lens and windows are also fabricated on the top part of this header body so that infrared radiation can enter the dish sample chamber below and then be redirected back above for signal processing.

Abstract: A method for calibrating a dual-beam NDIR gas sensor for detecting water vapor by obtaining a variant sensor components domain (“G0”) when there is no water vapor gas in the sample chamber, obtaining a physics measurement domain (“G”) for a set of known concentrations of the water vapor gas in the sample chamber, the known concentrations being measurable quantities exceeding zero, using G to calculate a G0i from a known concentration of water vapor in the sample chamber for each of multiple master calibration curves, and then selecting the master calibration curve with the lowest difference between its G0i and the G0 of the NDIR gas sensor as the calibration curve.

Abstract: An NDIR gas sensor methodology for the design of a dual-gas sensor for the detection of two gases having a mutually interfering infrared absorption band such as that for CO2 and H2O at around 2.70? or N2O and CO at around 4.40?. The output of this two-channel NDIR gas sensor remains drift-free over time and is also temperature independent because it uses three detection channels sharing the same sample chamber and all have exactly the same narrow band-pass filter. The first detection channel is filled with 100% nitrogen and its output is proportional to the concentration levels for both CO2 and H2O in the sample chamber. The second detection channel has two cells in series, one filled with a known concentration of H2O and another one with 100% CO2 gas, and its output is proportional principally only to the presence of H2O in the sample chamber. The third detection channel is filled with 100% CO2 gas and its output serves as the biased reference for this dual-gas NDIR gas sensor.

Abstract: An NDIR gas sensor and methodology use an absorption bias between signal and reference outputs to determine sample concentration of a gas being measured. The absorption bias is created by using a signal channel in a sample chamber with a signal path length that is greater than a reference path length of a reference channel in the sample chamber while both the signal and reference detectors have an identical narrow band pass filter with the same Center Wavelength (“CWL”), Full Width Half Maximum (FWHM) and transmittance efficiency at the CWL. Performance is improved when the reference detector and the signal detector share a common thermal platform that can also be shared by the sample chamber and the infrared source.

Abstract: Two detector elements are optically isolated by having them mounted (die-attached) on the same header so that the thermal tracking of the detectors respectively for the signal and reference channels is close to ideal. Furthermore, such an optical isolation technique or cross-interference suppression between the two detector elements mounted on the same header also allows the use of only one and the same narrow band pass interference filter covering both detectors. Thus the thermal tracking of the filters respectively for the signal and reference channels is also close to perfection as both channels share the same filter.
