  • Patent number: 7887143
    Abstract: An apparatus which allows for the counter rotation of a wheel accessory is disclosed. The apparatus is intended for mounting on a wheel of a vehicle. The apparatus has a base plate for attaching to the wheel, a transmission mechanism coupled to the base plate and a rotation prevention mount attached to the transmission mechanism. The transmission mechanism has an input shaft and an output shaft which extend in opposite directions from the transmission mechanism. The input shaft rotates in the direction of the vehicular wheel. The output shaft rotates counter to the vehicular wheel. A method for using a wheel accessory that rotates counter to the rotation of a vehicular wheel is also disclosed.

  • Patent number: 6509104
    Abstract: An article having a non-thrombogenic surface and a process for making the article are disclosed. The article is formed by (i) coating a polymeric substrate with a crosslinked chemical combination of a polymer having at least two amino substituted side chains, a crosslinking agent containing at least two crosslinking functional groups which react with amino groups on the polymer, and a linking agent containing a first functional group which reacts with a third functional group of the crosslinking agent, and (ii) contacting the coating on the substrate with an antithrombogenic agent which covalently bonds to a second functional group of the linking agent. In one example embodiment, the polymer is a polyamide having amino substituted alkyl chains on one side of the polyamide backbone, the crosslinking agent is a phosphine having the general formula (A)3P wherein A is hydroxyalkyl, the linking agent is a polyhydrazide and the antithrombogenic agent is heparin.

  • Patent number: 4759369
    Abstract: A pulse oximeter includes a capacitive d.c. blocking element to separate the time varying red and infra-red components of a light source transmitted through or reflected form the blood from the composite light signals. The magnitudes of the signal amplitudes are then digitized and converted for use as independent variables applied to a ROM based look-up table to determine blood oxygen saturation.
