A tracker apparatus, and method for tracking deployable units. The tracker apparatus includes a first sensor group having a first power consumption profile; a second sensor group having a second power consumption profile; a communication circuit having a first network interface for communicating with a control server; an energy storage; a processing circuitry; and a memory, wherein the memory includes instructions that, when executed by the processing circuitry, configure the tracker apparatus to: trigger the processing circuitry to awaken from a low power mode in response to a first input from a first sensor of the first sensor group exceeding a first threshold; activate a second sensor of the second sensor group in response to the first input corresponding to an unauthorized movement; and activate a tracking mode of the tracker apparatus, in response to a second input from the second sensor corresponding to an unauthorized movement.

A method of high-throughput printing and selective transfer of graphene onto a substrate includes the steps of: providing a thermal release tape having graphene adhered thereto; placing a substrate onto the graphene; pressing the thermal tape and the graphene against the substrate at a uniformly-distributed pressure; heating localized portions of the thermal tape and graphene using a localized heat source, thereby diminishing the adhesive properties of the thermal release tape in the localized portions and transferring graphene from said localized portions to the substrate; and separating the thermal release tape from the substrate. The method may include the further step of moving the localized heat source to selected positions on the thermal release tape during the heating step, thereby forming a pattern of heated portions. The method may use a laser beam as the localized heat source, movement of the laser beam being performed by a computer-controlled deflectable mirror.

A method for fabricating large-area, high-quality Graphene product. Specifically, the fabrication method uses a seed layer of exfoliated Graphene in combination with a substrate and a catalyst metal layer and introduces Carbon atoms to the Graphene seed, causing growth of high-quality Graphene product. The method of the invention combines some steps of current mechanical exfoliation techniques with other steps of the CVD process and adds a new technique to the fabrication method involving seed-based catalyst of large-area Graphene product growth.

In a method for adjusting the sensitivity of a photodetector, the bandgap of the photodetection material is adjusted by inducing strain in the photodetection material. Such adjustments can be made in situ and continuously, in a reproducible and repeatable manner. In embodiments of the method, the photodetection material is graphene, carbon nanotubes or graphene nanoribbon. The use of graphene permits a dynamically-adjustable sensitivity over a dynamic range of radiation having wavelengths of 1.38 microns or less, up to at least 60 microns. In an adjustable photodetector, a graphene layer is suspended over a silicon substrate by a layer of an insulating material. Adjusting the voltage across the graphene layer and the silicon substrate induces strain in the graphene layer by electrostatic attraction.

Active bandgap tuning of graphene for tunable photodetection applications

The RTD device of the present invention is comprised of a semiconductor substrate and a substantially thin conductive metal layer disposed upon the semiconductor substrate, wherein the conductive metal has a substantially linear temperature-resistance relationship. The conductive layer is etched into a convoluted RTD pattern, which consequently increases the overall resistance and minimizes the overall mass of the RTD assembly. A contact glass cover and a conductive metal-glass frit are placed over the RTD assembly to hermetically seal the RTD. The resultant structure can be 'upside-down' mounted onto a header or a flat shim so that the bottom surface of the semiconductor substrate is exposed to the external environment, thus shielding the RTD from external forces. The resultant structure is a low mass, highly conductive, leadless, and hermetically sealed RTD that accurately measures the temperature of liquids and gases and maintains fast response time in high temperatures and harsh environments.
