Abstract: The protective helmet includes a rigid outer shell where the shell includes an undulating cross-sectional profile. A layer of impact-energy-absorbing material is positioned adjacent to the shell. The undulating profile of the shell can be any type of load spreading undulating profile, such as that of a sinusoidal or triangular wave configuration. The undulating load-spreading profile can be on the inner surface of the shell, on the outer surface of the shell or the entire cross-section of the shell may be undulating. The unique undulating profile makes the shell more rigid and spreads the impact load across the surface of the shell to thereby spread the deformation of the padding layer to prevent the shell from bottoming out of the impact-energy-absorbing material during an impact. As a result, a safer and more effective protective helmet is provided.

Abstract: An exercise apparatus includes a housing, a pair of pivoting foot treadles and a pair of reciprocating bellows that support the foot treadles. A sealed air system including a conduit interconnects the bellows and is operable for reciprocating transfer of air from bellow to bellow. Each of the foot treadles is pivotably movable between upper and lower positions, and has a resting position between the upper and lower positions. The resting position of the foot treadles defines a resting position of the bellows while the upper and lower positions of the foot treadles respectively define elongated and compressed positions of the bellows. In use, the elongated and compressed positions of the bellows are each no more than 5 degrees off the center resting position thereby reducing stress on the bellows.

Abstract: The present invention provides a method of operating an infrared drip sensor in an enteral pump system to reduce false alarm conditions. The method consists of the following steps: optically coupling a infrared beam emitter with an infrared beam detector along an infrared beam path that extends through a drip chamber and intersects the drip path; monitoring the output signal of the infrared beam detector to detect pulses; monitoring the pulses for an interruption thereof; and running an infrared beam power update routine when an interruption is detected in the pulses, the infrared beam power update routine consisting of incrementally increasing a power level of the infrared beam until the power level of the infrared beam is sufficient to re-establish an output signal at the infrared beam detector.

Abstract: A breathable electrical heater element for a topical application device such as a wound dressing or a therapeutic heating pad is disclosed. The heater element is formed by photochemically etching a track pattern onto a porous metallised fabric (e.g. nickel coated woven polyester). The heater element has a skin or wound contact layer laminated to the front face of the heater element. An adhesive layer is laminated to the back face of the heater element. The adhesive layer forms an overhang to provide an adhesive border around the wound contact layer to adhere the device to the skin of a patient. Therapeutically active drugs (optionally microencapsulated) may be incorporated into the skin or wound contact layer. Operation of the heater element causes the skin or wound contact layer to release the active drugs to the skin or wound of the patient. Appropriate control of the temperature of the heater element allows control of the release of the active drugs.
