Abstract: A multichannel manifold cold plate with microchannels for cooling electronics. A main inlet is on a side of the microchannels opposite the cold plate and includes inlet channels with nozzles adjacent the microchannels. A main outlet is on a side of the microchannels opposite the cold plate and includes outlet channels with nozzles adjacent the microchannels. The inlet channels are interleaved with the outlet channels. In operation, the main inlet delivers a cooling fluid to the cold plate microchannels via the inlet channels and nozzles, and the main outlet receives the cooling fluid from the microchannels via the outlet channels and nozzles. This configuration provides a cooling fluid distribution pattern for efficient cooling of the electronics.

Abstract: A heat transfer device and method are disclosed. The device includes a working region (i.e., working substance) made from a first superconducting material having a superconducting state and a normal state when magnetized. The first superconducting material has a first energy gap while in the superconducting state. A substrate (i.e., cold reservoir) is connected to the working region at a first tunnel junction. The substrate may be a metallic substrate. A heat sink (i.e., hot reservoir) is connected to the working region at a second tunnel junction. The heat sink is made from a second superconducting material having a second energy gap that is larger than the first energy gap. In a particular example, the heat transfer device includes a metallic substrate is made from Copper, a working region made from Tantalum, a heat sink made from Niobium, and the first and second tunnel junctions are made from Tantalum Oxide.

Abstract: Methods of scanning an object using a pendulum gravimeter are disclosed. The pendulum gravimeter may include an interferometer, such as a Sagnac interferometer, to determine a displacement on the pendulum by way of a mirror attached to the pendulum. Scanning of the object may be performed in 1D, 2D, or 3D, and may result in an image of the object. In another aspect, a mass may be tracked while in motion using a pendulum gravimeter to detect the gravitational attraction of the object.

Abstract: In the present disclosure, energy harvesters based on quantum confinement structures, such as resonant quantum wells and/or quantum dots, are described. Also disclosed are methods of harvesting energy utilizing the described energy harvester and methods of manufacturing energy harvesters. Energy harvesting is the process by which energy is taken from the environment and transformed to provide power for electronics.
