摘要： Gas analyzers of the non-dispersive infrared radiation type which are designed to measure the concentration of one gas in a mixture of gases containing that gas. A novel, electrically modulated, stable, thick film infrared radiation emitter is employed to emit a beam of collimated, focused energy; and two electrically biased detectors are preferably used so that a ratioed, error eliminating output signal can be supplied to the failsafe, signal processing circuitry of the analyzer. The latter, and a conventional analog-to-digital convertor, supply information to a microcomputer which: (1) turns the infrared radiation emitter on and off; (2) controls a heater which keeps the infrared radiation detectors at a constant, precise temperature; and (3) controls displays of a variety of information concerning the gas being measured and the status of the gas analyzer. The microcomputer also accepts ambient temperature, barometric pressure, and other compensation factors. Typically, a disposable airway adapter will be included in the gas analyzer to confine the mixture of gases being analyzed to a path having a transverse dimension of precise and specific length and to provide an optical path across that stream of gases between the infrared radiation emitter and the infrared radiation detectors. The emitter and detectors are incorporated in a transducer head which can be detachably fixed to the airway adapter.

摘要： Power supplies for generating a stream of electrical pulses in which successive pulses have opposite polarities. The pulses are formed and outputted from pulse generating circuitry which has two complementary pairs of MOSFETs arranged in an H-bridge configuration. Other major components of the power supply are voltage regulators for supplying positive and negative operating pulses with selected, precisely controlled voltages to the driver and watchdog circuits for disenabling the pulse outputting circuitry if: the frequency of the operating pulses deviate from a selected range, the widths of the operating pulses exceed a selected maximum, extraneous pulses are present, or the voltage of the operating pulses falls below or exceeds selected maximums. In one important application, the power supply is employed to drive the emitter of an infrared radiation source.

摘要： A nondispersive infrared radiation source includes a base, a plurality of formed pins, a thick film resistor and an o-ring, the base has the shape of a cylinder and a plurality of grooves formed therein. A bore is formed in the base which is terminated by a bottom surface defined by a spherical radius. A reflective coating is applied upon the bottom surface. The plurality of formed pins are heat staked into the plurality of grooves and the o-ring is placed in one of the grooves. The thick film resistor comprises a substrate, a dielectric glass layer and a conductor layer, the substrate has a plurality of thick film resistors which are formed thereon. The plurality of thick film resistors are separated by use of a quadrapole laser. The thick film resistor is electrically connected to the plurality of pins with a solder connection. A DC source is electrically connected to the plurality of formed pins, and infrared light radiates from the resistive pad striking the reflective surface in the base, and the infrared light emits from the second end of the base.

摘要： Vehicle-mountable steps with platforms which have stowed and operational (deployed) positions. A latch mechanism positively locks the platform in the selected position. The step is designed for vehicles equipped with a ball-and-receiver type of trailer hitch and is coupled to the receiver of the hitch. The step is easily removed when the hitch is needed for towing but can otherwise be left on the vehicle as the platform of the step is located out-of-the-way beneath the vehicle when the platform is located in its stowed position.

摘要： Infrared radiation emitter units for gas analyzers and other applications. The emitter has a substrate with a film of electrically resistive, emissive material on one of its surfaces. The emitter is so mounted on an emitter unit base that it can freely expand as the emitter heats up. A lead frame commutator, employed to electrically connect the emitter to an external power source, also facilitates the assembly of the unit. A component with a plated, parabolic surface collimates and focuses into an appropriate beam the energy generated by the emitter.
