摘要:
The present invention provides for a system and method for creating, conducting and compiling the results of a survey. The system includes a backend platform and a user device having a related mobile application. The backend platform has at least one memory that stores computer-executable instructions and at least one processor configured to access the at least one memory. The processor is configured to create at least one channel and associated a target audience with that channel. The processor is also configured to create at least one survey and also associate the survey with the channel. The processor is also configured to associate at least one participant having a user device with the one channel. The survey is deployed to the participant once specific time and location criteria associated with the survey has been met. The location criteria can be met through the use of a physical location determination device. Once the participant responses to the survey, the results are provided to the backend platform.
摘要:
An implant stabilizes two adjacent bones of a joint, while enabling a natural kinematic relative movement of the bones. Support components are connected to each bone of the joint, and a flexible core is interposed between them. The core and at least one of the support components are provided with a smooth sliding surface upon which the core and support component may slide relative to each other, enabling a corresponding movement of the bones. The surfaces may have a mating curvature, to mimic a natural movement of the joint. The core is resilient, and may bend or compress, enabling the bones to move towards each other, and or to bend relative to each other.

An intervertebral prosthetic implant having a first endplate having a first surface configured to substantially engage with a first vertebral body and a second surface having an extension with a concave contact surface, the concave contact surface being spaced apart from the second surface. A second endplate is provided with a first surface configured to substantially engage with a second vertebral body and a second surface comprising a convex contact surface, and the second endplate having a securing element positioned along and above the second surface defining a first and second window on opposing sides of the second surface. The securing element extends along the width and length of the lower endplate and configured with an access hole. An extension portion extends from the first surface of the first endplate through the access hole of the securing element and contacts the second surface of the second endplate.

A four-component artificial intervertebral disc may provide six degrees of movement: flexion, extension, lateral bending, axial rotation, axial deflection, and anterior/posterior translation. The disc may include a superior endplate, a superior core, an inferior core, and an inferior endplate. The superior endplate may include a concave mating surface, and the inferior endplate may include a spherical mating surface. The superior endplate may roll across the superior core to provide flexion, extension, and lateral bending. The superior endplate may twist or rotate atop the superior core to provide axial rotation, and the superior endplate may slide over the superior core to provide anterior/posterior translation. The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.

Methods and apparatus for steering a vehicle are disclosed. A vehicle in accordance with an exemplary embodiment of the present invention is capable of operating in a first steering mode and a second steering mode. The vehicle may comprise an input device capable of providing an input signal indicating that operation in the second steering mode is desired. The vehicle may comprise an electronic control unit (ECU) capable of providing an enabling signal when the ECU determines that operation in the second steering mode is appropriate for the present riding conditions.

A wireless communication system and method is provided that uses a pseudo-random frequency sequence to reduce pico-net interference in a multi-band ultra wideband network. Pulse are transmitted using a pseudo-random sequence of frequencies such that neighboring pico-nets using the same technique can reduce band overlap thereby reducing mutual interference.

A method and system for generating multiple self-ID packets that are used for mapping a node topology is disclosed. The node topology is based on a computer system comprised of a high performance serial bus and a plurality of nodes coupled to the serial bus. Each node further includes an identification packet that is utilized for self-identifying itself on a network. In particular, a plurality of self-ID packets associated with the hardware actually present on the bus as well as a plurality of virtual nodes that are not actually present are generated during a self-ID process. Then, these self-ID packets are forwarded over the serial bus to identify themselves to other remaining nodes in the network. Thereafter, a topology mapping table from all of the self-ID packets is generated.
