摘要： A safety switch apparatus for disabling the operation of a hand-held appliance, e.g., a hair dryer, during periods of nonuse such as when the appliance is put down on a prescribed surface or placed in a non-functional position such as being held under a user's arm. In a first implementation, a sensor is coupled to control circuitry within the appliance to remove power from portions of the device, e.g., its motor and/or heater, when the appliance is proximate to an externally-provided magnetic field preferably provided from a magnetic element typically contained within a pad placeable on a work surface, within the work surface, or a wearable piece of clothing. In a second implementation, the converse occurs, i.e., a sensor is used to sense the presence of a user and to disable operation when the user is no longer present.

摘要： A hazardous area warning system with a non-directional magnetic field based proximity receiver for warning personnel of an attendant hazard. The receiver includes a x-axis receiver with an antenna directed in a x direction, a y-axis receiver with an antenna directed in a y direction and a z-axis receiver with an antenna directed in a z direction. The antennas may be a wire loop wrapped around a ferrite core. The output from each of the three receivers are combined in an adder. The combined result from the adder is representative of the distance between the receiver and a warning transmitter antenna. A comparator determines whether the received signal indicates an attendant hazard, i.e., the receiver is too close to the warning transmitter. The receiver wearer is warned of the attendant hazard, visually and/or tactilly, e.g., with warning lights and/or vibrations. An encoder encodes the signal indication and a transmitter transmits the encoded signal. A data link receiver (located, for example, at a potentially hazardous machine) receives the encoded signal from the proximity receiver. The data link receiver decodes the encoded signal and activates a safety indicator light in response to the decoded information, a green light indicating normal operation, a yellow light indicating a caution or potentially hazardous condition, and a red light indicating danger. The data link receiver may shutdown and/or disable the machinery in a caution or dangerous condition.

摘要： A safety system for a machine such as a wood chipping machine. The safety system has a passive sensor that may be worn on the machine operator's wrist, a sensing coil mounted to a feed chute of the machine for detecting the proximity of the passive sensor, and control circuitry which is responsive to the sensing coil. The circuitry provides a control signal for use in stopping operation of the machine. In use, the presence of the operator's arm in the chute near to parts of the machine that can cause injury will trigger the sensing coil and cause the machine to cease operating, thus circumventing injury to the operator.

摘要： One or more sensors located on or surrounding a dangerous condition anticipate when an individual is approaching a hazard zone associated with the dangerous condition and then arms an alarm and activates an interactive protective system which protects an individual from exposure to the dangerous condition. The interactive system comprises a protective garment adapted to be worn by the individual. The protective garment includes a sensor for sensing when the protective garment is being worn and a signalling device responsive to the sensor for generating a signal indicating when the protective garment is being worn. A detector and control device responsive to the signal from the signalling device triggers an alarm sensible to the individual when it is activated by the motion sensor and does not sense the signal from the signalling device.

摘要： A safety system is provided for a machine tool which has a frame and a tool. The safety system has a clamping device and a motion device. The clamping device is movable by the motion device from a working position, in which the tool is extended and can be used for working, to a safety position, in which the tool is retracted. The motion device has a first magnetic means connected to or arranged on the tool and a second magnetic means connected to or arranged on the frame, such that movement of the tool by the motion device from the working position to the safety position can be triggered and/or at least partially performed by magnetic force.

摘要： A safety system prevents cutting machine operators from being accidentally carried through the infeed chute into the machine's cutting mechanism. An operator wears a safety device on his wrist and/or ankle and a sensor array mounts on opposing sides of the cutting machine's infeed chute. The sensor array elements are wound in opposite directions and connect in series opposing. The magnetic field of the safety device induces a current in the sensor array as it moves in the proximity of the sensor array. The safety system generates a signal which is proportional to the sum of the induced currents. When the signal exceeds a threshold, the safety system shuts off power to the feed mechanism and/or the cutting blades of the cutting machine, preventing injury to the operator.

Also provided is a radio frequency device that sends radio frequency signals, the radio frequency device being capable of sensing the magnetic field and generating a radio frequency response. In the safety system, the generator generates the magnetic field for a first predefined time period, and thereafter senses for a radio frequency response signal from the radio frequency device within a second predefined time period. The invention also provides for shaping safety zones by overlaying magnetic field boundaries to produce a different boundary. The invention also provides for varying the strength of magnetic fields by adjusting a width of a timed pulse.
