摘要:
The invention relates to a system (1) of detection and analysis of bodies situated in the working space of an operating machine provided with a control member, an operating machine comprising such a system and a method of controlling such an operating machine, wherein the system comprises an emitter (2) of sound waves, a receiver (3) of reflected sound waves, an analyzer (4) of these reflected sound waves and an interface device (5) to interface the analyzer (4) and the control member of the operating machine one to the other, wherein the interface device (5) is adapted to act on the control member of the operating machine depending on the response of the analyzer (4).
摘要:
The present invention relates to a laser interlock system that allows laser radiation to be generated when an inspector and a subject correctly wear safety glasses during use of a photo-acoustic imaging apparatus, thereby protecting the eyes of the inspector and the subject and preventing unnecessary power consumption. The laser interlock system includes a sensing unit to sense whether or not contact between a user and safety glasses occurs, a light source unit to generate laser radiation, and a control unit that determines, based on an output value from the sensing unit, whether or not the user is wearing the safety glasses, and generates an interlock signal to turn on or off the light source unit for selective laser generation according to the determination. The sensing unit further includes a left measurement unit and a right measurement unit, wherein the control unit determines whether or not the user wears the safety glasses based on if each of the output values of the left measurement unit and the right measurement unit exceeds a preset first threshold value.
摘要:
A numerically controlled machining apparatus for machining workpieces made of wood or a material similar to wood is disclosed, having a safety device for the safety of an operator, wherein the distortion of a magnetic field caused by the presence of the operator is detected by a sensor, formed of a metal band with an antenna function, applied to a movable part of the apparatus, so as to be able to stop the apparatus before the contact between the operator and the moving part.
摘要:
An obstruction detection apparatus is provided for use in closing a power driven vent, such as a window that is located in an opening. The vent includes a first closing edge that moves as the vent is closed and the opening includes a second closing edge that is contacted by the first closing edge when the vent is in a fully closed position. The apparatus includes a detector configured to detect an obstruction at all points along the second closing edge without requiring contact between the obstruction and the vent and to deliver a detection signal when an obstruction is detected. A controller is connected to the detector for receiving the detection signal and delivering a corresponding alarm signal.
摘要:
A sensing mechanism (12) for detecting user contact with an active portion (26) of the power tool (10) is provided. In addition, a safety mechanism (14) for preventing prolonged user contact with the active portion (26) of a power tool (10) is provided. The safety mechanism (14) is configured to actuate upon receipt of a signal from the sensing mechanism (12). According to a first aspect, the safety mechanism (14) is arranged to rapidly displace the active portion (26) away from a user extremity. Alternatively, according to a second aspect, the safety mechanism (14) is arranged to rapidly urge an extremity of the user away from the active portion (26) of the power tool (10).

An obstruction detection apparatus is provided for use in closing a power driven vent, such as a window (1035), that is located in an opening (1042). The vent includes a first closing edge that moves as the vent is closed and the opening includes a second closing edge that is contacted by the first closing edge when the vent is in a fully closed position. The apparatus includes a detector (1060) configured to detect an obstruction at all points along the second closing edge without requiring contact between the obstruction and the vent and to deliver a detection signal when an obstruction is detected. A controller is connected to the detector for receiving the detection signal and delivering a corresponding alarm signal.

An obstruction detection apparatus (44) is provided for use in closing a power driven vent, such as a window, that is located in an opening. The vent includes a first closing edge that moves as the vent is closed and the opening includes a second closing edge that is contacted by the first closing edge when the vent is in a fully closed position. The apparatus includes a detector (52) configured to detect an obstruction at points all along the second closing edge without requiring contact between the obstruction and the vent and to deliver a detection signal when an obstruction is detected. A controller (46) is connected to the detector for receiving the detection signal and delivering a corresponding alarm signal (48).
