Abstract: Missing covers on pipes of a pool circulation system can create a hair and limb entrapment hazard for swimmers. The present invention provides pipe insert with a cylindrical body having a plurality of fins that extend into the cylindrical body to prevent the entrapment of limbs in the pipes of the pool circulation system. The fins further comprise a geometry that easily sheds hair strands to prevent hair from getting trapped in the pipe.

Abstract: Missing and broken drain covers for swimming pools, spas and/or other applications expose swimmers to dangers including entrapment and evisceration. An anti-evisceration ring of this invention is attached to an opening of a sump or frame and provides a non-planar edge that prevents the formation of a vacuum by a body part and thereby preventing injuries to swimmers.

Abstract: An apparatus and method for monitoring driver fatigue and inattention. A device introduces a controlled disturbance requiring driver compensation into a steering system of a vehicle and monitors for an expected driver compensation in response to the disturbance. When the actual compensation does not sufficiently match the expected compensation the driver is alerted and vehicle functions can automatically be activated or reduced.

Abstract: A safety cable system for a fitness device including a resistance load and a user interface device. A redundant cable apparatus connects the resistance load to the user interface device for lifting the resistance load by a force applied to the user interface device. The redundant cable apparatus comprises two cables extending in redundant cable paths between the resistance load and the user interface device. The two cables can share the resistance load or one of the cables can be dormant until failure of the other cable.

Abstract: The subject invention is directed to methods, processes and decisions on test outcomes for testing for faulty, therefor dangerous, performance of zero speed indicators that are used to control the opening of barriers guarding moving machine components. The indicators may be tested by removing them from the components during operation without shutting down production or in certain situations the indicators may be tested during the run down phase of the components caused by machine stop initiations. The tests allow to anticipate and hence prevent hazardous opening of barriers due to a faulty zero speed indication. Additionally, the invention is directed to testing of the insertion of motion interference devices in conjunction with zero speed indicators, both of which must perform correctly in order to permit the unlocking and opening of the protective barrier. There are included various exemplary devices for effecting the testing function.

Abstract: This invention relates to novel systems for testing guards closures or barriers used on hazardous machinery for personnel protection. The guards are tested separately or in conjunction with safety devices which may include interlocks, locking mechanisms and latching devices. The testing process proceeds without having to shut down the machine on which the guarding system is mounted. Testers are incorporated in the process for establishing the integrity of the safety devices and for executing self-testing. Also included are various novel devices that are unable in such systems.

Abstract: An anti-vacuum drain cover is defined by a centrally supported grating together with at least one outwardly extending tributary tube. When the grating is obstructed, the fluid may still be suctioned through at least one tributary tube preventing the formation of vacuum conditions within the main drain. The outboard end of the tributary tube may be fashioned in an irregular pattern to preclude deliberate blockage with one's hand. The grating may further incorporate an anti-hair entanglement design, such as self shedding cantilever elements, which provide anti-hair snare properties. The tributary tubes may be straight or curved with sufficient length to minimize hair entanglement through the tributary tubes. The outboard ends of the tributary tubes may also be located sufficiently far from the grating to eliminate the possibility of simultaneously blocking all suction sites with a single body.

Abstract: A window locking system which prevents unintended opening of a window. The window locking system includes a base element which is attachable to a window and which forms a slot. Disposed within the slot is a latching member pivotally connected to the base element. The latching member includes a handle element and an oppositely disposed latching finger extending from opposite faces of the base element. A locking key which is rotatable between a locking position and an unlocking position is connected to the base element. The locking key prevents the latching member from pivoting from a closed position to an open position when oriented in its locking position.

Abstract: A drain structure for disposal with a pool or hot tub where suction or vacuum forces are normally present. The drain has interiorly a plurality of grating members having lower surfaces adapted to facilitate release of entangled hair. In certain embodiments, the grating elements are cantilevered from the inner wall of the drain and having tapered lower release surfaces. In another embodiment, the lower surfaces comprise share lower edges for severing entangled hair.
