Abstract: ABSTRACT OF THE DISCLOSURE    A pulse combustor apparatus including a combustor tube having open ends and containing at least one com-bustion zone where combustion of a fuel occurs and heat is released, resulting in the formation of a standing acoustic mode with nodes and anti-nodes in the tube.        The combustion zone is located approximately half the distance between the acoustic pressure node and anti-node where the acoustic pressure oscillation lags  the acoustic velocity oscillation by approximately one-quarter period of the oscillation.  Furthermore, the combustion air must flow towards the acoustic pres-sure anti-node.  The fundamental principle relating to the occurrence of the pulsations in the combustor is the interaction between the combustion processes and both the non-zero acoustic velocity and acoustic pres-sure oscillations at the designated combustion zone location.  In a preferred embodiment employing a vertical combustor tube, the combustion zone is located one quarter of the length of the tube away from the bottom of the combustor tube and a heat exchanger is located three quarters of the length of the combustor tube away from the bottom of the combustor tube.

Abstract: Abstract of the Disclosure:         In a multiple QAM system in which a pair of quadrature-phase carrier signals is modulated by a first and a second input digital signal, each representative of N or less levels, into a quadrature-phase amplitude modulated signal having M signal points on a phase plane where M is equal to N2, a code converting unit (41) converts the digital signals according to a predetermined rule into a first and a second modulating signal for use in modulating the carrier signals with the M signal points arranged approximately at a circle of a diameter which is shorter than a diagonal of a square of a side corresponding to the N levels.  In a counterpart demodulat-ing system, a pair of demodulated signals is derived from the amplitude modulated signal and converted into reproductions of the respective digital signals according to an inverse of the predetermined rule.

Abstract: ABSTRACT OF THE DISCLOSURE    A signal processing system that directly determines the phase difference existing between two periodic electrical signals and a mass flow meter employing the system are provided.  The system shifts together two comparison signals corresponding to the periodic electrical signals and accumulates the shift that is necessary to force the phase angles of the comparison signals to be equal.  The mass flow meter employs a moving conduit through which the fluid whose mass flow rate is to be measured flows and which generates Coriolis forces.  The Coriolis forces affect the motion of the moving conduit and motion sensors provide periodic signals corresponding to the motion of the conduit.  Under flow conditions, the Coriolis forces cause the electrical signals produced by the sensors to be out of phase with each other to an extent that depends on the magnitude of the mass flow rate.  The system provided by the invention is employed by the meter to measure the phase difference between the electrical signals to provide an indication of the mass flow rate through the moving conduit.

Abstract: ABSTRACT OF THE DISCLOSURE         The specification discloses an automatic rearview mirror control circuit which models the physiological response of the human eye to fluctuating light levels as observed in typical driving conditions.  The control circuit calculates an ambient light signal representative of light levels within the driver's field of view and a rear light signal representative of light levels in a direction generally incident to the reflective element.  The reflectivity of the reflective element is controlled to optimize rear image information while minimizing on rear image glare at the driver's eyes.  The control circuit includes a multiple-rate filter for time-averaging an ambient light signal over a shorter time period during increasing ambient light intensities than during decreasing ambient light intensities to simulate the more rapid adaptation of the human eye to increasing light intensities than to decreasing light intensities.  The control circuit automatically alters or adjusts the sensitivity of the mirror to rear light based on the ambient light level.  The mirror is more sensitive to rear light in relatively low ambient light, such as experienced on rural highways, than in relatively high ambient light, such as is experienced on urban highways.  The control circuit calculates ambient light within the driver's field of view.  The calculation takes into account the forward light, rear light reflected from the interior rearview mirror, and/or rear light reflected from the windshield, pillars, headliner, and exterior rearview mirrors.
