Abstract: Stovetop fires are among the more prevalent of resident fire hazards and smoke detectors are among the most prevalent and economical forms of residential fire alarms. Automatic stovetop fire extinguishers can prevent property damage and even personal injury; however, these stovetop fire extinguishers may also limit smoke emissions and the subsequent detection of smoke. While an initial fire may be efficiently subdued by an automatic stovetop fire extinguisher, it is often desirable to alert present and future occupants of a fire hazardous condition. A sound based fire alarm system and method are described herein, which detects a sound burst emitted upon deployment of an automatic stovetop fire extinguisher and triggers a continuous fire alarm to alert occupants of a potentially fire hazardous condition. Alarm signals can be audible, visual, or both. The system may be a stand alone system and use battery power for affordability and ease of installation.

Abstract: When a count value concerning with the travel of the vehicle in a two-wheel drive state reaches or exceeds a predetermined value, the state of drive in a transfer is temporarily switched to a four-wheel drive state by connecting a synchromesh mechanism while keeping a mesh clutch disconnected, so that rotary members that do not rotate during the two-wheel drive state, such as a second output shaft, are temporarily rotated. Thus, the rotary members are restrained from remaining in contact at fixed portions and therefore being partially worn. Besides, there is no need to provide a mechanism for temporarily rotating the rotary members, such as the second output shaft, separately from the synchromesh mechanism that is normally provided for the four-wheel drive travel in the related art. Therefore, it is possible to improve durability without involving cost increase, space efficiency deterioration, etc.

Abstract: A parking brake control device performs a releasing control with good precision by more precisely maintaining clearance between a friction-applying member and a friction-applied member. During a releasing control, a timing at which a braking force generated by an electric parking brake 2 drops to zero is detected based on a change in a motor current, and a second releasing operation time is set according to the magnitude of the motor current at the time the braking force drops to zero. This makes it possible for the second releasing operation time to be set in accordance with fluctuations in a motor load due to temperature changes or the like. Therefore, a clearance between a brake pad and a brake disc can be kept constant according to the motor load.
