  • Publication number: 20110310928
    Abstract: A temperature determination apparatus includes a signal detection section having an A/D input port, a thermistor that is connected to the A/D input port and outputs an analogue signal to the A/D input port, and a switch section that shifts a level of the analogue signal to a low level. The signal detection section determines that a control signal having a priority higher than that of an output detection process of the thermistor is generated when it is detected that the analogue signal to be input to the A/D input port is in the low level.

    Abstract: Disclosed is an audio system including a group of loudspeakers that form a sound field by delivering into a single space sound signals passed through respective ones of a plurality of sound signal channels. This audio system is comprised of two characteristic-variable equalizers that are cascaded to each other to constitute a part of the sound signal channels; a sound field characteristics detecting part for supplying test signals through the sound signal channels and detecting sound pressure in the sound field and thereby obtaining a sound pressure signal; and a characteristics adjusting part for adjusting, based on the sound pressure signal, equalizing characteristics of the characteristic-variable equalizers individually and with respect to each of the sound signal channels. The sound field characteristics detecting part selectively generates test signals of different bands.

  • Publication number: 20100202490
    Abstract: A circuit body includes a flexible insulation sheet with an electric circuit pattern having wiring patterns and a temperature sensor arranged in the electric circuit pattern. The electric circuit pattern has a temperature-sensor connecting portion and a heat-concentrating pattern formed integrally with the temperature-sensor connecting portion so as to have a larger width than that of the wiring pattern. The temperature sensor is touched through the heat-concentrating pattern to an object to be measured. The wiring patterns and the heat-concentrating pattern are formed integrally on a primary surface of the insulation sheet by printing. An additional heat-concentrating pattern is further formed on a secondary surface of the insulation sheet at a position corresponding to the temperature-sensor connecting portion. The heat-concentrating patterns are bent integrally with the insulation sheet and touched to the object to be measured.
