Abstract: A clip on car visor extension for use on a vehicle's existing sun visor, effectively blocks out sunrays which the visor itself is not capable of blocking on its' own. The clip on car visor extension is made up of a clip member and a glare reducing sheet element, rotatably fastened on the clip member. The clip member has two elongated legs joined at the closed end by a connecting leg. The glare reducing sheet element is preferably rectangular shaped. The clip on car visor extension can be moved laterally or horizontally on the vehicles sun visor as needed by moving the clip member and radially rotating the glare reducing sheet element to an angle as needed depending on the user's position and sun's position in the sky.

Abstract: Message handling in a local area network including switches and clients is provided. At least one of the switches is a peer switch that is capable of monitoring a status of another switch, and at least one switch connects the clients redundantly. A station announcement message is sent by the peer switch for at least one client of the other switch. In each station message announcement, there is inserted a source address of the other switch. The other switches handle the station message announcement as though the station message announcement came from the client.

Abstract: A control system and method provides automatic adjustments in a heavy duty vehicle that effectively redistributes the weight among the various wheel axles. A plurality of sensors are associated with the plurality of wheel axles on the vehicle. An electronic controller gathers information from the sensors and determines the weight at each wheel axle. The electronic controller then automatically determines adjustments that can be made to effectively redistribute the weight among the wheel axles in the event that the weight at any one axle is outside of a preselected range. The adjustments preferably are made by automatically moving the position of an adjustable “fifth wheel” relative to the cab portion. Additionally, this invention provides the capability of automatically adjusting the position of at least one trailer wheel axle. The adjustments can be made dynamically even while the vehicle is in motion.

Abstract: In an assay in which a ligand is labelled by conjugation to a dihydrophthalazinedione (DPD), e.g. luminol or isoluminol, and the conjugated DPD is reacted with an oxidant, e.g. hydrogen peroxide, and an active heme group catalyst, e.g. microperoxidase, the light intensity is enhanced by certain sterically hindered amines defined as saturated bicyclic compounds having a nitrogen atom at one or both bridgehead positions or a piperidine ring compound having four C.sub.1-4 alkyl groups at the 2- and 6- positions. 1,4-Diazabicyclo[2.2.2]-octane, known as "DABCO" is preferred.
