Abstract: Apparatuses, methods, and systems are disclosed for data-aided channel state information (CSI) measurement and reporting. One apparatus includes at least one processor and coupled with the at least one memory and configured to cause the apparatus to: decode a received signal to determine a decoded data sequence; perform at least one data-aided CSI measurement based on both the received signal and the decoded data sequence; and transmit a CSI report based on CSI reporting criteria and the at least one data-aided CSI measurement, where the CSI report comprises at least a portion of the at least one data-aided CSI measurement.

Abstract: A cervical collar device for applying a constant upward push force includes a flexible neck brace and a constant upward push force device. The flexible neck brace includes a top and a bottom with a height therebetween, and a first side and a second side with a length therebetween. The height and the length of the flexible neck brace is configured for placement around a neck of a user. The constant upward push force device is positioned inside said flexible neck brace.

Abstract: An implantable dialysis connection assembly for connecting first and second catheters positioned with a vein to first and second terminals of a dialysis machine. The assembly includes a housing having first, second and third recesses extending into a face side thereof. A first port is positioned within the first recess for receiving the first terminal and retaining an end of the first terminal within the first recess. A second port is positioned within the second recess for receiving the second terminal and retaining an end of the second terminal within the second recess. A third port is positioned within the third recess for connecting to a supply of heparin for deposit within the third recess. The third port is connected to the first port for supplying heparin thereto by a first conduit and the third port is connected to the second port for supplying heparin thereto by a second conduit. First and second connection devices connect the first and second ports to the first and second conduits, respectively.
