Abstract: A watercraft propulsion system for moving a watercraft along a waterway having a bottom and a surface, wherein the watercraft presents a port side and a starboard side. The watercraft propulsion system comprises a boom assembly having a proximal end and a distal end, with the proximal end being rotatably coupled with the watercraft. The watercraft additionally comprises a wheel mounted to the distal end of the boom. The wheel includes at least one generally radially-extending blade assembly, with the blade assembly comprising a primary blade and a secondary blade. The secondary blade extends at an angle with respect to the primary blade so as to present a fluid channel between the primary blade and the secondary blade.

Abstract: A cutterhead for dredging water-bed material from a body of water. The cutterhead comprises a shroud presenting a front margin for receiving water-bed material into an interior space of the shroud. The shroud additionally includes a port from which water-bed material can be removed from the interior space of the shroud. The cutterhead additionally comprises a rotatable cutterbar at least partially received within the interior space of the shroud. The cutterhead further comprises a debris guard positioned between the cutterbar and the port. The debris guard is operable to filter the water-bed material removed from the shroud through the port. At least a portion of the debris guard that faces the cutterbar includes a concave shape.

Abstract: A circulation facilitating apparatus comprising a pneumatic assembly and first and second leg assemblies. The pneumatic assembly comprises a pump assembly, a control assembly, an air controller assembly and an energizing assembly. The control assembly controls the pump assembly. The control assembly includes a microprocessor and a system for programming the microprocessor. The programming system programs at least a cycle time and at least a hold time. The air controller assembly is coupled to the pump assembly. Each leg assembly includes a bladder, an air passage assembly and a housing. A treatment method is likewise disclosed.

Abstract: An interior rearview mirror assembly for a vehicle includes a casing with a reflective element and a storage space. The storage space provides storage for at least one accessory and for storing the accessory in the location easily accessible by an occupant of the vehicle whereby the accessory can be inserted into and removed from the storage space for use by an occupant of the vehicle. The storage space may take the form of a recess provided in a top wall of the casing, a recessed portion provided in a front wall, back wall, or end wall of the casing. In one form, the recessed portion houses a pendent accessory which is dockable in and removable from the storage space for use by an occupant of the vehicle. For example, the pendent accessory may comprise a light assembly which is useable as a flashlight independently of the interior rearview mirror assembly or useable as a map light when docked in the mirror assembly. The storage space may also be used to hold workpieces or the like.

Abstract: An interior rearview mirror assembly includes a human machine interface having at least one user actuatable input accessible at a portion of the mirror casing. The user actuatable input provides user input to at least one element of circuitry that is disposed in the mirror casing, the interior rearview mirror assembly and/or an accessory module. The circuitry is associated with at least one of (i) a moisture sensor, (ii) a blower motor, (iii) a cabin air monitoring device that monitors the air within the cabin of the vehicle, (iv) a cabin air monitoring device that monitors the level of carbon monoxide in the air within the cabin of the vehicle, (v) an air intake, (vi) a remote ignition system, (vii) a humidity sensing device, and (viii) a display device disposed behind a transflective mirror reflector of the interior rearview mirror assembly and visible to the driver when displaying information.
