Abstract: Tapered root threaded hollow perforated interbody spinal fusion implants are disclosed for placement into a disc space in a human spine between adjacent vertebral bodies. The implants have opposite arcuate portions with lockable screws passing therethrough for engaging each of the adjacent vertebral bodies. The implants are adapted for use in side-by-side pairs such that a portion of the circumference of a first implant nests within the circumference of a second implant, so as to have a reduced combined width.
Abstract: A system and method are disclosed for providing a complete architectural and procedural solution to wireless subscriber loyalty issues. A flexible promotion creation environment allows mobile phone operators to rapidly create and deploy various incentive programs and other such loyalty schemes; together with a data mining and profiling method for tracking, monitoring and analysing subscriber (or aggregate) usage information associated with given promotions. The proposed data mining and profiling method purposely incents specific subscriber behaviors by triggering a point-based reward scheme based on the dynamic screening of event records which are correlated with incented behaviors. Wherein a threshold is assigned based on usage information for a particular promotion; upon realization of which, the subscriber is, immediately notified of the reward through a plurality of means including e-mail, voice notification and by way of Short Message Service (SMS) at their wireless handset.

Abstract: An artificial interbody spinal implant adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies is disclosed. The implant has an asymmetrical leading end adapted to sit upon the more peripheral areas, such as the apophyseal rim and the apophyseal rim area, of the vertebral end plate region of the vertebral bodies without protruding therefrom. The asymmetrical leading end allows for the safe use of an implant of maximum length for the implantation space into which it is installed. The implant can also include an asymmetric trailing end adapted to sit upon the more peripheral areas of the vertebral end plate region of the vertebral bodies.
Abstract: A screw formed of cortical bone for use in the human body with an implant having a screw hole for receiving at least a portion of a screw therethrough, includes a shaft with a thread along at least a portion of its length. The thread has an outer diameter dimensioned to pass through the screw hole in the implant. The trailing end of the screw is configured to cooperatively engage at least a portion of the screw hole of the implant so as to prevent the screw from linear motion along the mid-longitudinal axis of the shaft in a direction opposite to the direction of insertion when the screw is threaded through the screw hole to attach the implant to a bone portion of the human body. The screw is formed substantially of cortical bone of a single cortical thickness.
Abstract: A plating system includes bone portion engaging anchors coupled to a connecting plate in moveable relationship to vary the spacing between the anchoring points of the plating system to the bone portions. The plating system includes instrumentation and method for installation thereof. The plating system is capable of both passive and active dynamization and the ability to produce the former from the latter.
Abstract: A flanged interbody spinal fusion implant for insertion at least in part between adjacent vertebral bodies has opposed upper and lower surfaces adapted to contact each of the adjacent vertebral bodies from within the disc space, a leading end for insertion between the adjacent vertebral bodies, and a trailing end opposite the leading end. The trailing end has a height greater than the maximum height of the disc space forming a flanged portion adapted to overlie a part of the anterior aspects of the vertebral bodies adjacent and proximate the disc space to be fused. The flanged portion has at least two bone screw receiving holes, at least one each adapted to overlie each of the adjacent vertebral bodies at least in part. The implant has at least one locking element to lock one or more of the bone screws inserted in the bone screw receiving holes. Instrumentation for inserting the implant, forming screw holes in the vertebral body, and for locking the locking elements are disclosed.
Abstract: A system and method of wireless communication power control is provided which allows for adjusting power levels without requiring high bandwidth for control. Embodiments allocate subcarriers into unequal power groups, each group having a consistent subcarrier power level. Using interference parameter information from a user, a subcarrier is assigned from a group having adequate power to maintain the user's required power level. In general, users with higher power requirements, such as those near cell boundaries, will be assigned subcarriers from a group having a higher power level. A cell may use a different allocation than a neighbor, so that subcarriers with the highest power level in one cell may not also have the highest power level in a neighboring cell. Such diversity may reduce inter-cell interference of the subcarriers near a cell boundary, since no two subcarriers are transmitted with highest power simultaneously by neighboring base stations.
Abstract: A device and method for use in a human spine to prepare a space between adjacent vertebral bodies and into the vertebral end plates to receive an implantable insert. The device includes a handle, a shaft, and a mounting member at one end of the shaft. An abrading element is mounted on the mounting member and is coupled to a drive mechanism. The drive mechanism is operable to move the abrading element in at least one degree of freedom to create surfaces having predetermined contours in the end plates of the adjacent vertebral bodies.
Abstract: An interbody spinal implant is formed of cortical bone adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies. An asymmetrical leading end on the implant is adapted to sit upon the peripheral areas, such as the apophyseal rim and the apophyseal rim area, of the vertebral end plate region of the vertebral bodies without protruding therefrom. The asymmetrical leading end allows for the safe use of an implant of maximum length for the implantation space into which it is installed. The implant can also include an asymmetric trailing end adapted to sit upon the more peripheral areas of the vertebral end plate region of the vertebral bodies.
Abstract: An OFDMA communication system includes a plurality of terminals, with at least one of the terminals including at least one type of multi-user decoder adapted to decode a signal intended for the at least one terminal received on a subchannel of the system and adapted to decode at least a portion of an interfering signal received on the subchannel. The system also includes a plurality of base stations. Each of the base stations may be in communication with others of the base stations for exchanging information about data throughput for particular terminals in cells of the system using particular subchannels in the cells. Each of the base stations assigns the subchannels to terminals in the cell of the base station so as to maximize data throughput in the entire system.
Abstract: Systems and methods which implement cooperative random or quasi-random beam forming as between a plurality of base stations in a wireless network to reduce multi-cell interference are shown. For example, a plurality of base stations in a wireless network cooperate to provide frequency resources, such as channels, subchannels, subcarriers, etc., in a plurality of randomesque beams. In operation, subscriber stations preferably analyze signals as received on a plurality of the randomesque beams to determine one or more “best” beams for use in communication between the subscriber station and base station. Assuming an identified beam is available for use by the subscriber station, payload communications may be provided using one or more beams identified by the subscriber station as a “best” beam. The base stations of the wireless network preferably cooperate to periodically reform the randomesque beams.
Abstract: Methods and systems for improved channel estimation that jointly consider interference contributions and noise contributions separately. Associated method involve measuring pilot channel signals at a receiver and then determining what component of the measured pilot channel signals are attributable to a serving BS and what component of the measured pilot channel signals are attributable to an interfering BS. This information is used to determine a product of the pilot channel signals attributable to the serving BS and the pilot channel signal attributable to the interfering BS, where the found product is used to estimate said channel.

Abstract: According to some embodiments, a registry is displayed. The registry may, for example, indicate resources available from a plurality of remote network access devices via a communications network. Moreover, a personal network address may be associated with each available resource, the personal network address including an destination address portion and an application program identifier portion. A direct communications link may then be established between a first network access device hosting an available resource and a second network address device using the personal network address associated with the resource.
Abstract: Rapid uplink synchronization is enabled by reducing a 2D search problem to two 1D search problems, which can generally be performed in less time. Advantage is taken of fact that a mobile device sends a ranging code on multiple sub-carriers. Using the assumption that adjacent sub-carriers will have approximately equivalent channel characteristics, phase ambiguity can be removed by differentially combining pairs of adjacent sub-carriers. Once the phase ambiguity is removed, the code, timing, and power level may be determined relatively quickly. In one embodiment, the values of correlations between received signals and possible codes are compared with a threshold.
