Abstract: Systems and methods of the disclosed subject matter for converting light into electrical signals are provided including receiving light input and outputting electrical signals proportional to the light input with a sensor, increasing a transimpedance gain of an amplifier to amplify the electrical signals with a T-network of resistors coupled to the amplifier and the sensor, filtering the electrical signals with a filter circuit coupled to the amplifier and the T-network of resistors to increase noise rejection in a predetermined frequency range, and outputting the filtered electrical signals.

Abstract: Apparatus, systems, methods, and related computer program products for handling temperature variation with optoelectronic components of a hazard detection system are described herein. A power characteristic of an optoelectronic component of the hazard detection system may be used to determine a temperature of an environment of the hazard detection system. A power characteristic of an optoelectronic component of the hazard detection system may be used to determine a smoke condition of an environment of the hazard detection system. Optoelectronic components of the hazard detection system may be optically coupled to determine a smoke condition of an environment of the hazard detection system. Multiple optoelectronics of the hazard detection system may be operative to detect forward scatter and back scatter of one or more types of light to determine a characteristic of a hazard particle.

Abstract: Systems for ensuring an audible alarm circuit sounds at a minimum magnitude of loudness are provided. Different circuitry embodiments discussed herein are each capable of assisting the audible alarm circuit in maintaining a minimum loudness threshold. Audible alarm circuit operation optimization can be achieved using embodiments that fall within anyone of four general categories: compensation networks, direct drive, dynamic tuning, and microphone feedback based dynamic tuning. Use of such circuitry can increase production yields by compensating for manufacturing variations of alarm components and aging characteristics of the components.
