Abstract: Immersion cooling systems, apparatus, and related methods for cooling electronic computing platforms and/or associated electronic components are disclosed herein. An immersion cooling chassis includes a first face, a second face opposite the first face, a third face disposed between the first face and the second face, the third face perpendicular to the first face, a fourth face disposed between the first face and the second face, the fourth face perpendicular to the first face and opposite the third face, and a first portion to be cooled via a first convection of a coolant fluid, the first portion including a coolant inlet defined in the third face, and a coolant outlet defined in the first face, and a second portion to be cooled via a second convection of air, the second portion including an air inlet defined in the first face between the fourth face and the coolant outlet.

Abstract: An apparatus is described. The apparatus includes a coolant distribution unit having a first primary loop output to provide first cooled immersion liquid to an immersion chamber and a second primary loop output to provide second cooled immersion liquid to one or more cold plates within the immersion chamber.

Abstract: An Improved garage door opener wherein a motor is coupled to the drive shaft of the door at upper side with gear attached to the drive shaft thereof to operate the garage door and a clutch mechanism is provided to move the gear from engaging location to allow the door to be manually opened or closed. This invention results in a quieter environment both in garage and in the room above garage and a substantial simplification over current garage door openers which require a rail and trolley mechanism for opening and closing the door. No extra space required for this opener.

Abstract: A scatter correction device for radiative tomographic scanners is disclosed. The device comprises at least one steady support component and multiple beam stoppers made of high Z materials such as lead and wolfram. Each beam stopper has two ends fixed on the steady support component respectively. Theses beam stoppers can thus be sustained at fixed locations by the steady support component. During scanning an object, the device is placed between the object and detectors. But when the scatter correction device is applied to a CT scanner, the device is placed between object and radiation source. It attenuates part of the primary radiation with very small affects on the scattered radiation.

Abstract: Photonic Band Gap (PBG) structures are utilized in microwave components as filters to suppress unwanted signals because they have the ability to produce a bandstop effect at certain frequency range depending on the structural dimensions. The unique property of PBG structures is due to the periodic change of the dielectric permittivity so interferences are created with the traveling electromagnetic waves. Such periodic arrangement could exist either inside of the dielectric substrate or in the ground plane of a microstrip transmission line structure. This invention provides tunable or switchable planar PBG structures, which contains lattice pattern of periodic perforations inside of the ground plane. The tuning or switching of the bandstop characteristics is achieved by depositing a conducting island surrounded by a layer of controllable thin film with variable conductivities.
