A monitoring system includes at least one detector having a housing that carries at least one ambient condition sensor. Control circuits carried by the housing are coupled to the at least one ambient condition sensor. A separate audio input transducer carried by the housing is coupled to the control circuits, wherein the control circuits include signal processing circuits coupled to the separate audio input transducer. The signal processing circuits cancel predetermined audio received from the separate audio input transducer and output a processed speech signal that is coupled to speech recognition circuitry. The speech recognition circuitry recognizes selected speech to implement predetermined functions.

A system and method for communicating between a base and a remote device in a security system. The base receives an audio signal from a telephone network via a panel and then frequency modulates the audio signal at a carrier frequency to generate an FM signal. The remote device receives the FM signal from the base, determines a phase error signal representing the phase error between the received FM signal and an output signal of a voltage controlled oscillator, determines a difference between the carrier frequency and a center frequency of the voltage controlled oscillator, and, if there is a difference, then changes the center frequency of the voltage controlled oscillator to match the carrier frequency of the FM signal.

A half-wave rectifier including an input port for receiving an incoming AC signal, an output port for outputting a half-wave rectified signal, an operational amplifier including inverting and non-inverting input terminals and an output terminal, the inverting input terminal connected to a ground reference and a non-inverting input terminal coupled to a negative feedback loop and a first resistor. The negative feedback loop including a second resistor coupled between a first node and a second node, the first node coupling the output terminal and the output port and the second node coupling the non-inverting input terminal and the second resistor. A capacitor is coupled to the input port and in series with the first resistor.

AC to DC conversion circuit

The present invention is a method of operating a speaker by converting an audio signal to a pulse-width modulated signal that has a plurality of positive pulses and a plurality of negative pulses as a function of the audio signal, then driving an H-bridge circuit interconnected to a speaker, wherein the H-bridge circuit comprises an A-side and a B-side, wherein the A-side comprises a first switching transistor and a second switching transistor, and wherein the B-side comprises a first switching transistor and a second switching transistor. For each positive pulse, the A-side of the H-bridge circuit is driven by pushing the first switching transistor of the A-side while grounding the second switching transistor of the A-side. For each negative pulse, the B-side of the H-bridge circuit is driven by pushing the first switching transistor of the B-side while grounding the second switching transistor of the B-side.

Class D amplifier with increased efficiency

A system and method for recovering a high frequency component of a slew rate controlled signal propagating along a transmission line enables the high frequency component to be recovered after being lost because of slew rate control and transmission line low pass filtering effects. The system includes a wave shaping circuit for receiving and shaping the slew rate controlled signal to recover the high frequency component. The method includes receiving the slew rate controlled signal, and recovering the high frequency component by shaping the slew rate controlled signal to produce a shaped signal, where the shaped signal includes the received slew rate controlled signal and the high frequency component.

System and method for extending universal bus line length

The invention includes a circuit to monitor batteries arranged in a parallel battery configuration for charge/discharge battery circuit operation. The circuit selectively tests for each battery's presence in a battery holder or receptacle without interrupting circuit discharging operation, e.g., physical removal, and communicates a fault condition if the battery is determined to be missing. The inventive circuit enables existing or legacy control circuitry operating with the circuit to detect individual missing batteries where the legacy control circuitry is constructed to detect only missing circuit charge paths states.

Security system communication with a user device via electronic means, including via e-mail transmitted over the internet are provided. A security system interface receives a signal indicating an occurrence of an event, such as a fault or alarm condition, in a zone of the security system; a memory stores a user e-mail address associated with the security system and the address of a server for providing internet service, such as an ISP server; and an e-mail generator transmits to the server an e-mail message based on the event. The communication node in such a system may be integrated with the control panel of the security system. The e-mail generator can transmit the e-mail using SMTP or other TCP/IP. An attachment of the e-mail, such as a picture or an audio or video file relevant to the event or the zone may be transmitted.
