Patent number: 11799398Abstract: Several types of piezoelectric MEMS vibration energy harvesters are described herein as well as methods of fabricating the vibration energy harvesters. The vibration energy harvesters generally comprise a serpentine structure having a central longitudinal axis; a piezoelectric film deposited on a surface of the serpentine structure; a central mass located at a mid-portion of the central longitudinal axis; two lateral masses positioned at opposing corners of the serpentine structure; anchor points at two other opposing corners of the serpentine structure; and upper and lower electrode layers. The energy harvesters have a 180 degree rotational symmetry about the central mass and when the serpentine structure experiences a strain, the piezoelectric film generates a voltage. The geometry of the energy harvesters allows for lower frequency and wider bandwidth operation as well as higher power density.Type: GrantFiled: May 3, 2019Date of Patent: October 24, 2023Assignee: Memorial University of NewfoundlandInventors: Lihong Zhang, Seyedfakhreddin Nabavi

Patent number: 9784236Abstract: A water mill, power generator, for use underwater, has a flexible support shaft which permits the water current to orient the turbine axis substantially parallel to the direction of flow so that the force of the water on the blades is optimized for a given turbine, without the need for slip ring style connections between the generator at the turbine and the 5 anchored base. Optionally, the design features fins or cowlings on the flexible support shaft to further improve reorientation of the turbine with the water current or flow acting as the source of power; and/or output power links or power conditioning systems at the anchored base.

Patent number: 9609881Abstract: An improved apparatus for processing sea cucumbers having stages for orienting/aligning, cutting, splitting, flattening, eviscerating and cleaning the sea cucumber, and for collecting the eviscerated innards. A method for the automated splitting and evisceration of sea cucumbers using the apparatus of the present disclosure. A flattening plate and trough during the orienting/aligning step relax the sea cucumber and discourage its defence mechanisms. A wedge shaped flattening plate splits and flattens the sea cucumber immediately after the incision. Pronged discs maintain positioning of the sea cucumber during an aggressive wash and brush cleaning cycle, which may be repeated. Optionally, a vacuum may suction off a portion of the innards prior to cleaning.Type: GrantFiled: October 6, 2016Date of Patent: April 4, 2017Assignee: MEMORIAL UNIVERSITY OF NEWFOUNDLANDInventors: Joseph Singleton, Mark Ingerman, Stephen King
