Abstract: Systems and apparatuses for blood oxygenation are disclosed. A system includes a first layer defining a plurality of banks of first channels each extending in a first direction. The plurality of banks of first channels are configured to receive blood via a trunk channel. The system includes a second layer defining a bank of second channels extending in a second direction. The bank of second channels are configured to receive oxygen. The first direction is different from the second direction. The system includes a membrane disposed between the first layer and the second layer and configured to cause the oxygen to permeate from the second layer to the first layer to oxygenate the blood.

Abstract: Attachments of the present disclosure combines the optimal practices of the traditional bracket-wire system and more recent resilient appliance (e.g., CTAs and polymeric bands) systems. The attachments include prescribed in/outs, torques and angulations designed utilizing the straight wire methodology for determining the bonding location on a particular tooth of the dental arch. A marriage of bracket prescription with attachment placement can help the treating professional to better visualize the treatment outcome with the tray or band on the patient.

Abstract: Old and new standard, regular electrical-only, non-optical connectors, such as USB, Lightning, HDMI, Ethernet, are modified for migrating into new optical capabilities. These electrical-only connectors are integrated with active microelectronic/optical conversion components inside for converting electrical signals to optical signals and optical signals back to electrical signals. Newly integrated connectors are 100% physically and functionally compatible with the original electrical-only connectors which have the same sizes, colors, shapes, cut-outs, mating cavities, mounting holes, pins and foot-prints can directly replace the old connectors to install onto the same surface-mount pads, through-holes of PCB of existing product designs.

Abstract: A system and method of a structural panel includes a first outer sheet and a second outer sheet, the first outer sheet and second outer sheet including a polygon shape; a core arrangement sandwiched between the first outer sheet and the second outer sheet, the core arrangement comprising two or more discrete members arranged adjacent each other, the discrete members shaped or structured to reduce crack initiation and propagation within the core arrangement.

Abstract: A compensation device for maintaining a desired signal quality in transmitted signals includes a signal strength loss curve comparison component configured to compare a predetermined signal strength loss curve to a low band signal strength of a radio-frequency (RF) signal in an amplified forward path of a premise device.

Abstract: A frequency band selection device that can be inserted into a signal transmission line of a CATV system on the premise of a user includes at least two signal path sets between a tap side and a premise side. Each signal path set includes two discrete signal paths, a high frequency signal path for a downstream bandwidth and a low frequency signal path for an upstream bandwidth. The high frequency signal path and the low frequency signal path are separated by a cut-off transition frequency that is different for each signal path set. The device further includes a switch controller having at least two discrete switch positions. The switch controller chooses one of the switch positions as a result of an information signal. Each of the switch positions corresponds to a respective one of the signal path sets.

Abstract: Performances are enhanced and improved tremendously for existing USB connectors with new improvised fiber-optical connection features and their capabilities. Existing USB connectors, such as user-friendly reversible Type-A and USB Type-C connectors are modified, improvised and retrofitted using means of allocating unused spaces and surfaces to allow fiber-optical wires and connections inside the user-friendly reversible Type-A and USB Type-C connectors. This modification will not affect the regular functions and performances of the user-friendly reversible Type-A and USB Type-C connections. New fiber-optical connections will enhance and improve reversible Type A and USB Type-C as compared to regular user-friendly reversible Type-A and Type-C connectors that have only copper wire connections.
