Abstract: An air treatment apparatus for conditioning air or providing ventilation of air includes: a casing of an apparatus main body; a first sensor disposed outside the casing and configured to output a signal in conformity with a first communication standard; a conversion unit configured to convert the signal output from the first sensor into a signal conforming to a second communication standard higher in tolerance to noise than the first communication standard and to output the signal thus converted; and a main control unit disposed in the casing and configured to receive the signal output from the conversion unit.

Abstract: An airbag device for the body instantaneously activates an airbag without malfunctions. When an absolute value of an angular velocity detected by an angular velocity sensor exceeds a predetermined angular velocity value, angular velocity values are integrated from a most recent detected value to an oldest value within a predetermined time period, and if an absolute value of a resultant value of integral exceeds a predetermined value and an acceleration detected by an acceleration sensor is smaller than a predetermined acceleration, the airbag is inflated. Based on the value of the integral of the angular velocities, a case in which an angular velocity gradually increases is distinguished from a case in which an angular velocity momentarily increases, so the airbag device effectively prevents malfunctions caused by an action other than falling over. Additionally, because it is unnecessary to intentionally delay determination to prevent malfunctions, the airbag can instantaneously be inflated.

Abstract: A harness type safety belt absorbs dropping shocks to a user who accidentally falls from an elevated position. If the user fails to apply a rope hook to a life line and falls from the elevated position, an air bag in a mounting body inflates to absorb the dropping shock to reduce the dropping impact applied to the user. If the user falls with the rope hook connected to the life line, the rope suspends the user. The body of the user is supported by a waist belt, shoulder belts and thigh belts. Therefore a tension applied by the rope to the body of the user is dispersed to each of the belts so the body of the user is stably supported.

Abstract: The present invention provides a harness type safety belt capable of absorbing a dropping shock to a user even if the user accidentally falls from an elevated position. According to the present invention, in such a case that a user A fails to apply a hook of a rope to a life line and the user A falls from an elevated position, an air bag 2 provided in a mounting body 1 is inflated. Therefore, the air bag 2 can absorb a dropping shock and the dropping impact applied to the user A can be reduced. In addition, in the case where the user A falls with the hook of the rope being connected to the life line, the user A is suspended by the rope. The body of the user A is supported by not only a waist part belt 1b but also shoulder part belts 1a and thigh part belts 1c. Therefore a tension applied from the rope to the body of the user can be dispersed to each of the belts 1a, 1b and 1c and the body of the user can be stably supported.

Abstract: A falling shock absorbing apparatus for a wheelchair is provided capable of absorbing shock to the user in the case of falling of a wheelchair. In other words, the falling shock absorbing apparatus for wheelchair of the present invention includes an inflatable air bag for covering a predetermined parts of the wheelchair user when inflating, an inflation apparatus for inflating the air bag, an inclination detecting apparatus for detecting inclination of the wheelchair relative to the surface upon which the wheelchair is moved, and a controller for activating the inflation apparatus to inflate the air bag when inclination of the wheelchair is detected by the inclination detecting apparatus. Thus, the air bag inflates to cover the predetermined parts of the wheelchair user when the wheelchair is tilted.

Abstract: The present invention provides a shock absorbing aid for a human body ensuring an effective alleviation of a shock to the human body. In the present invention, air bags are inflated upon a detection of separation of a wearer's body from an object of contact, such as when the wearer has fallen from an aerial place, thereby making it possible to absorb a shock to the human body with the aid of the air bags even when the wearer has directly dropped on the ground or the like.
