Abstract: Methods for ultrasonically imaging a heterogeneous 3D-cell population without physically probing are provided. The method can comprises: pulsing ultrasound waves having a wave frequency of about 10 MHz to about 2 GHz through a lens rod, wherein the lens rod focuses the ultrasound waves onto the cell population via a concave lens-head (e.g., comprising sapphire), and wherein the cell population is positioned on the reflective surface such that the ultrasound waves are reflected back to the lens-head; receiving the reflected waves through the lens head and the lens rod at a signal receiver; scanning the lens-head across multiple points in the x,y plane; and at each point in the x,y plane, moving the lens-head in a z-direction such that a signal is received at multiple intervals in the z-direction for each point in the x,y plane.

Abstract: Modern living involves using a significant amount of energy, much of which may be wasted or not used efficiently. This apparatus and methodology focuses on potentially wasted energy that is being produced by ambient vibration. Bi-modal broad band energy and/or specific frequency harvester/scavengers utilize the physics of local resonance in acousto-elastic metamaterials (AEMM structures). Frequency selectivity of a harvester depends on the mass of a core resonator, soft material that houses the central mass/resonator, and the base material which is used to manufacture the metamaterial. Piezoelectric materials are known to produce electrical current when they are deformed mechanically. Ambient energy is available in the form of vibration and noise, e.g. car vibration, acoustic noise from heavy machineries, vibration from rails, which is lost, if not otherwise harvested. A smart metamaterial can scavenge/harvest ambient low frequency vibration for charging batteries such that the ambient energy may become a renewable source of energy to power low power electronic gadgets on the go. Power output for a unit cell AEMM embodiment is optimized through one or more of multi-frequency/multi-modal harvesting, geometric optimization, and PZT position optimization.

Abstract: An autonomous all-terrain robot for agricultural industries is designed to install support stakes inground on plant beds while being able to self-navigate. Apparatus and method provide a robot having the ability to perform the actions of navigating between plant beds and to determine a precise location and depth to place each supporting stake. The purpose of the stakes is to support the plants with weak stems. Part of some planting processes require stakes to support a plant as it begins to grow. from a two- or three-week-old plant to a fully mature plant. The presently disclosed subject matter provides a machine that can aid in the planting process of both bell peppers and eggplants and similar crops, used to drive stakes into planting beds. The presently disclosed technology (such as specific robotic device or robot) can work 24/7, weather permitting, while providing an efficient and completely hands-free way to install stakes needed in the planting process.
