Patent number: 4796205Abstract: A fire alarm system which makes fire determination based on a novel idea which considers various changes of the physical phenomena in the surroundings caused in relation with the occurrence of a fire in terms of changes of vectors. These changes in the physical phenomena are detected by the detecting section in the form of analog data and processed by a data sampling section as sampled data and stored in a storing section in such a manner as discriminating them by the detecting sections. The tendencies of the changes are computed in a first computing section and the vectors representing the present or future conditions of the physical phenomena are computed from the sampled data. The vector is compared in a comparing section with a preliminarily set data related to the fire detection and when the relation therebetween is not a predetermined one, an alarm is given through an alarming section.Type: GrantFiled: August 12, 1985Date of Patent: January 3, 1989Assignee: Hochiki Corp.Inventors: Hiromitsu Ishii, Yukio Yamauchi

Patent number: 4665372Abstract: A method for producing sinusoidal waves uses the steps of generating a plurality of clock signals during a 2.pi. period, using the clock signals to control the generation of 2.pi. periodical square wave pulses having preselected length and phase relationships during respective ones of the clock signals and applying the square wave pulses to a low pass filter. The reduction of pulse length as well as the phase relationship of the pulses is evaluated from a system of equations by setting the odd harmonics of corresponding Fourier series to zero or to a predetermined minimum value. A circuit device utilizing this method uses a switching amplifier operated in a binary sequence having a period corresponding to the desired sine wave period and a low pass filter connected to the output of the amplifier.Type: GrantFiled: February 11, 1985Date of Patent: May 12, 1987Assignee: Honeywell GmbHInventor: Peter U.

Patent number: 4647935Abstract: An apparatus for tracking phase discontinuities introduced into a received signal at known instants is disclosed. The phase discontinuities are introduced into the received signal by command signals derived from a system timing reference. A controlled oscillator generates an output signal at the same frequency as the received signal. The controlled oscillator introduces into the output signal a phase jump having a magnitude and timing determined by a control signal applied to its input. A synchronous detector responsive to phase jumps in the received signal generates the control signal so as to introduce a phase jump into the output signal at the known instants equal in magnitude and sign to the detected phase jumps. The controlled oscillator and synchronous detector constitute a delta phase tracking loop which is capable of tracking the discontinuities in phase.Type: GrantFiled: November 20, 1985Date of Patent: March 3, 1987Assignee: Starnav CorporationInventor: Luis F.

Patent number: 4644287Abstract: Charge transfer device output signals typically include an information component which is contaminated with both on-chip amplifier noise and reset noise. For reducing these noise components, the device output signal is applied to first and second synchronous detectors. The first synchronous detector is responsive to a first reference carrier signal for maximizing at its output the information component while the second synchronous detector is responsive to a second reference carrier for maximizing at its output the noise components. The synchronous detector output signals are then differentially combined so as to substantially reduce the noise components from the contaminated information component.Type: GrantFiled: March 10, 1986Date of Patent: February 17, 1987Assignee: RCA CorporationInventor: Peter A.

Patent number: 4638262Abstract: A high frequency oscillation type proximity switch including an oscillating circuit having an adjusting resistor changing the oscillating state, the switch being adapted to detect an object by a decrease in the oscillation output due to the approach of the object, wherein when the oscillation output decreases, the switch detects the object while changing the resistance of the adjusting resistor to facilitate the restart of oscillation. Thus, when the object disappears after the detection of the object, oscillation is easily started, so that response to the detection of objects is improved. Further, by providing the output circuit with an integrating circuit having a time constant greater than the commercial alternating current, the oscillation is caused to be intermittent at the zero-cross point in the alternating current, thus making it possible to construct an anti-magnetic field type proximity switch which is usable even in an environment where an intense ac magnetic field is present.Type: GrantFiled: March 8, 1985Date of Patent: January 20, 1987Assignee: Omron Tateisi Electronics Co.Inventor: Kiyoshi Miyamoto
