Abstract: A corpectomy device has an inner member telescopingly disposed in an outer member so that the inner member is movable in an axial direction. The inner and outer members are hollow, defining a chamber, and include apertures in communication with the chamber. A locking clip engages the inner and outer members to fix the position of the inner member with respect to the outer member. The longitudinal dimension of the device is adjustable by distracting the inner member so that the inner member extends from the outer member and moving the locking clip from an unlocked position to a locked position.

Abstract: A computational method to estimate the carrier frequency offset (CFO) of wireless communication systems using novel phase measurements is disclosed. The computation is carried out in the Diophantine framework defined in this disclosure. It effectively resolves the phase ambiguity (due to 2π crossing) commonly embedded in the phase measurements. The phase ambiguity is an issue for wireless packet communications when a significant initial CFO cannot be synchronized reliably to a common reference packet per packet. A typical application is vehicle to everything (V2X) communications employed by the Intelligent Transportation Systems (ITS) worldwide, as included in the IEEE 802.11 WLAN standard as well as in the 3GPP LTE and 5G standards. An emerging application that needs to address high Doppler frequency is non-terrestrial network (NTN) in 5G wireless communications. The disclosed computational framework offers scalable computational complexity for implementation tradeoff to meet both cost and performance requirements.

Abstract: An apparatus and method of determining the position location of a moving platform without using any GPS signals such as in the GPS-denial environment is disclosed. A direction finding system is employed to receive signals from a source of known position location and to compute the look angles. The look angles include the azimuth and the elevation information. The position location (e.g., latitude and longitude) of the moving platform is determined from the computed azimuth and elevation and the known position location of a remote signal source. There is no interactive communications required between the moving platform and the remote signal source. Consequently, the disclosed method is a passive approach employing a direction finding system to determine the position location of the moving platform from the received non-GPS signals. The position location obtained via this method is also applicable to GPS spoofing detection when the GPS is considered available.

Abstract: Surgically implantable tissue engineered intervertebral disc tissues that effectively replicate the physicochemical properties of the corresponding in vivo tissues are provided. Methods for producing such tissues can involve culturing the intervertebral disc cells to produce cells surrounded by an extracellular matrix and culturing the cells and matrix on a semipermeable membrane to form a cohesive tissue.

Abstract: In a communication system including a plurality of user terminals in a full-mesh network and a network-control-station terminal, control-function data is communicated between an individual user terminal and the network-control-station terminal in a given TDMA-frame communication channel while the given TDMA-frame communication channel is also being used for communicating user-communication data between user terminals. The control-function data and the user-communication data are communicated within control-function time slots and user-communication time slots respectively of the given TDMA-frame communication channel. The time slots for such communications are dynamically assigned in response to time-slot assignment signals communicated from the network-control-station terminal when the communication link between the user terminals is established. Control-function data is communicated from the user terminals to the network-control-station terminal in even-numbered control-function time slots of different given TDMA-frame communication channels; and control-function data is communicated from the network-control-station to the user terminals in odd-numbered control-function time slots of different given TDMA-frame communication channels.
