Abstract: An interactive animal earphone device for providing noise attenuation, as well as voice commands, in noisy environments is described. The device typically includes a core member, and an audio processing system (at least a processing device combined with an in-ear speaker, and alternatively, combined with an outer-ear microphone and an in-ear canal microphone) for capturing/transmitting/interpreting sounds from the animal (including biological noises captured in the ear canal) and digitally controlling over the animal perception of its sound environment. The earphone device may further include, without limitation, a tracking technology (GPS module), a gyroscope, health monitoring sensors, a wireless module, and a memory for storing data recorded from in-ear canal and outer-ear microphones and other sensors.

Abstract: A drive member for a cage of a spiral conveyor, the drive member comprising a cage-bar and an engagement member. The cage-bar comprises a ridge extending along a longitudinal axis of the cage-bar, the ridge being adapted to mate with an inner side of a conveyor belt. The cage-bar has a conical shape and a driving ridge in a single part with coating to protect against wear. At the belt entrance of the spiral conveyor, the sanitary monopiece direct drive cage-bar have an UHMW (Ultra-High-Molecular-Weight) polyethylene bloc overlapped to help engagement of the belt as specified by manufacturer of the belt. The custom bended shape of the cage-bar allows using several different conical angles to reduce belt tension. The monopiece cage-bar also allows applications where great temperature changes are required because the thermal dilatation will not causes gap in the driving ridge.

Abstract: An endless conveyor chain assembly (10) includes two piece enclosed curved track sections (15) having curved sections (15) for the passage therethrough of a series of conveyor chain links (12). Outer race (18) of the curved track sections (15) include an impervious horizontal bottom wall (22) that is U-shaped in cross section for retaining any lubricants or other liquids or debris. Inner race (20) with a wear strip (44) attached thereto is removable from the outer race (18) without having to cut the curved conveyor track sections (15) from the track and without having to remove the conveyor chain from the track when performing maintenance to the conveyor chain assembly.

Abstract: A personal watercraft has a pole having a forward portion pivotally connected to the deck. Handlebars are operatively connected to the rearward portion of the pole. A pole support is connected to the pole at one end and to the deck at the other in order to support the pole above the deck. The pole support is preferably connected to the pole and the deck with latches. The length of the pole support can be adjusted in order to accommodate different sizes of riders.
