Abstract: The present invention provides a protective visor for use during the treatment of hair comprising a bill attached to a headband, wherein the bill is composed of high density foam and the headband is composed of soft foam, the protective visor being adopted to attach to a person's head just below that person's hair line, thereby protecting that person from fluids running off of her hair or hot air blown in her face.

Abstract: A method for the shipment and preservation of organ-derived cells in which the shipping medium is in a firm, substantially congealed state at ambient and chilled temperatures, but becomes substantially fluid upon reaching body temperature. The medium in its fluid state can be poured over cultured cells or tissue slices or used to suspend isolated cells and then can be chilled to reach its congealed state for shipment.

Abstract: Applicant's invention includes an apparatus and associated method for precisely aligning two pieces of weldable material and tack welding the two pieces together. The apparatus contains means for independently securing the two pieces of weldable material and for centering the junction of the two pieces in line with the tack welding electrodes.

Abstract: The Driver's Associate assists a driver of a vehicle to more efficiently reach a desired destination, to record the route driven, and to provide driving summary reports. The present invention uses a unique method for tracking the dead-reckoned coordinate of the vehicle by using a sum-of-squares or .chi..sup.2 minimization algorithm for plotting the navigation route, tracking the vehicle through the road map database, and for normalizing the vehicle's location between the dead-reckoned coordinate and the roadway projected coordinate. The present invention also uses a Singular Value Decomposition method for optimizing the normalization process so that we can track a vehicle's location more accurately than other navigation devices.
