An implant preshaped before placement anteriorly between a superior endplate and an inferior endplate within a void created by a transcorporeal procedure in a vertebra, the implant having no circular cross-sectional dimension.

Method of inserting a surgical implant within a transcorporeal void

A method of performing an anterior cervical fusion procedure is provided. The method includes creating a void in a first vertebral body of a cervical vertebra, the void beginning anteriorly and directed posteriorly creating an exit at a posterior aspect of the vertebral body, after the creation of the void in the first vertebral body, removing at least a portion of a cervical intervertebral disc, the disc located between and adjacent to the first vertebral body and a second vertebral body, and performing a fusion procedure between the first vertebral body and the second vertebral body.

Method and implant for converting a transcorporeal corpectomy procedure to an intervertebral discectomy with fusion procedure

This invention is the method of treating an ailment associated with the cervical portion of the spine by performing an intravertebral corpectomy that includes the steps of removing the vertebral corpus to define a working channel for the surgeon to gain access to the epidural space so as to attend to and perform a procedure on the pathology. This method obviates the problems incidental to more radical cervical spine operations such as discectomy or corpectomy which requires removal of a portion of the vertebra and adjacent intervertebral discs for decompression of the cervical spinal cord and spinal nerves and using a bone graft with or without a metal plate and screws to reconstruct the spine and provide stability. Prior to terminating the surgery, the opening formed by the removed vertebral corpus is fitted and/or filled with a suitable implant.

Method for performing a surgical operation on the cervical portion of the spine

A module operable to be mounted onto a surface of a board. The module includes a linear accelerometer to provide a first measurement output corresponding to a measurement of linear acceleration in at least one axis, and a first rotation sensor operable to provide a second measurement output corresponding to a measurement of rotation about at least one axis. The accelerometer and the first rotation sensor are formed on a first substrate. The module further includes an application specific integrated circuit (ASIC) to receive both the first measurement output from the linear accelerometer and the second measurement output from the first rotation sensor. The ASIC includes an analog-to-digital converter and is implemented on a second substrate. The first substrate is vertically bonded to the second substrate.

Integrated motion processing unit (MPU) with MEMS inertial sensing and embedded digital electronics

This invention relates to an implant having the capability of being adjusted to fit symmetrical and asymmetrical shaped voids formed in the bone or outside the bone of a patient. The implant can be individualized so as to accommodate various distortion in the void and can be disposed as a series of similar shaped implants that have different dimensions and/or characteristics to allow the surgeon to select an appropriate implant from said series.

Method and apparatus for placement into iatrogenically created skeletal voids

Method and apparatus for performing a surgical operation on the cervical portion of the spine

Systems, methods, and apparatus for performing deduced reckoning navigation without a constraint relationship between orientation of a sensor platform and a direction of travel of an object are described herein. A sensor fusion component can be configured to receive data from sensors of a sensor platform coupled to a pedestrian; and generate world coordinate information based on the data. Further, a gait recognition component can be configured to record one or more walking patterns of the pedestrian in a training database; and determine whether the world coordinate information is associated with a walking pattern of the one or more walking patterns. Furthermore, a position estimation component can be configured to estimate a position of the pedestrian based on the world coordinate information if the world coordinate information is associated with the walking pattern, regardless of an orientation of the sensor platform with respect to the position of the pedestrian.

Interfacing application programs and motion sensors of a device. In one aspect, a high-level command is received from an application program running on a motion sensing device, where the application program implements one of multiple different types of applications available for use on the device. The high-level command requests high-level information derived from the output of motion sensors of the device that include rotational motion sensors and linear motion sensors. The command is translated to cause low-level processing of motion sensor data output by the motion sensors, the low-level processing following requirements of the type of application and determining the high-level information in response to the command. The application program is ignorant of the low-level processing, and the high-level information is provided to the application program.

Interfacing application programs and motion sensors of a device

Handheld electronic devices including motion sensing and processing. In one aspect, a handheld electronic device includes a set of motion sensors provided on a single sensor wafer, including at least one gyroscope sensing rotational rate of the device around at least three axes and at least one accelerometer sensing gravity and linear acceleration of the device along the at least three axes. Memory stores sensor data derived from the at least one gyroscope and accelerometer, where the sensor data describes movement of the device including a rotation of the device around at least one of the three axes of the device, the rotation causing interaction with the device. The memory is provided on an electronics wafer positioned vertically with respect to the sensor wafer and substantially parallel to the sensor wafer. The electronics wafer is vertically bonded to and electrically connected to the sensor wafer.

Controlling and accessing content using motion processing on mobile devices

Systems and methods for human hand gesture recognition through a training mode and a recognition mode are disclosed. In the training mode, a user can move a handheld device with a hand gesture intended to represent a command. Sensors within the handheld device can record raw data, which can be processed to obtain a set of values corresponding to a set of discrete features, which is stored in a database and associated with the intended command. The process is repeated for various hand gestures representing different commands. In the recognition mode, the user can move the handheld device with a hand gesture. A computer system can compare a set of values corresponding to a set of discrete features derived from the hand gesture with the sets of values stored in the database, select a command with the closest match and displays and/or executes the command.

Handheld computer systems and techniques for character and command recognition related to human movements

Selectable communication interface configurations for motion sensing devices. In one aspect, a module for a motion sensing device includes a motion processor connected to a device component and a first motion sensor, and a multiplexer having first and second positions. Only one of the multiplexer positions is selectable at a time, where the first position selectively couples the first motion sensor and the device component using a first bus, and the second position selectively couples the first motion sensor and the motion processor using a second bus, wherein communication of information over the second bus does not influence a communication bandwidth of the first bus.
