  • Publication number: 20220203918
    Abstract: A child seat system for a vehicle includes a child harness, with the harness comprising a plurality of straps provided in at least a three-point harness system, the sensor being arranged to detect when a selected strap is flaccid, whereby to assist in the alerting to a parent or carer that the harness is improperly fastened. The child seat system for a vehicle can provides a warning whether it be audible or visual warning; the warning can be directed through a Bluetooth device, for example reducing the volume of speakers in relation to the play back of songs/discussion or a radio broadcast or otherwise. The warning may be provided with a delay, whereby to enable a period of time to place a child within the seat, with regard to the presence of a seat sensor—such as a weight sensor or thermal sensor.

  • Patent number: 10957496
    Abstract: A connector includes a male, key-like member that is operably received in a female connector body. The key-like member includes a stem for operative association with a cord or other body and a distal element. The female connector has a body defining a proximal portion for operative association with a cord or other body and a slot extending along a surface of the body to an aperture for receiving a distal element of a first connector element. A first inside channel extends from the slot at a distal end of the connector to a depth from the surface of the slot. A second inside channel extends from the aperture to the first channel. One of the first and second connectors is provided with a sensor. The sensor indicates that the first connector element is located at the distal portion of the inside channel.

  • Patent number: 10062529
    Abstract: The present invention relates to motor safety devices as used in increasing numbers for the killing of engines or disengaging propulsion units from motors, when there are no operators to maintain control of an apparatus or vehicle such as jet-ski, boat, go-kart and the like or personnel to oversee use of a motorised tool or the like. Motor boat operators on a boat have been known to fall overboard without being detected by the operator of the boat. Such runaway boats have been known to seriously injure the operator of the boat in the water since a runaway boat tends to circle back to the place where the operator has fallen overboard. The present invention is also applicable to other types of equipment such as motorised gymnasium equipment, hand operated power tools, such as agricultural and arboriculturist equipment and wood working tools.
