A near-to-eye display system for forming an image as an illuminated region on a retina of at least one eye of a user is disclosed. The system includes a source of modulated light, a proximal optic positionable adjacent an eye of the user to receive the modulated light. The proximal optic has a plurality of groups of optically redirecting regions. The optically redirecting regions are configured to direct a plurality of beams of the modulated light into a pupil of the eye to form a contiguous illuminated portion of the retina of the eye. A first group of the optically redirecting regions is configured to receive modulated light from the source and redirect beams of the modulated light into the pupil of the eye for illumination of a first portion of the retina. A second group of the optically redirecting regions is configured to receive modulated light from the source and redirect beams of the modulated light into the pupil of the eye for illumination of a second portion of the retina.

Systems and methods of use for continuous analyte measurement of a host's vascular system are provided. In some embodiments, a continuous glucose measurement system includes a vascular access device, a sensor and sensor electronics, the system being configured for insertion into communication with a host's circulatory system.

Exploiting the substantive reciprocity of internode channel responses through dynamic, adaptive modification of receive and transmit weights, enables locally enabled global optimization of a multipoint, wireless electromagnetic communications network of communication nodes. Each diversity-channel-capable node uses computationally efficient exploitation of pilot tone data and diversity-adaptive signal processing of the weightings and the signal to further convey optimization and channel information which promote local and thereby network-global efficiency. The preferred embodiment performs complex digital signal manipulation that includes a linear combining and linear distribution of the transmit and receive weights, the generation of piloting signals containing origination and destination node information, as well as interference-avoiding pseudorandom delay timing, and both symbol and multitione encoding, to gain the benefit of substantive orthogonality at the physical level without requiring actual substantive orthogonality at the physical level.

A surgical stapler that may have a head assembly, a stapling assembly, a shield, a base head, a handle assembly, and a shaft assembly. A head assembly may have an anvil and anvil shaft, as well as a stapling assembly. A stapling assembly may have a trocar that can be removeably detachable with the anvil, a cannula extension, and a plurality of staples. A shield may be configured to retract from a first extended position where the shield generally covers the stapling assembly or the head assembly, to a second retracted position where the shield generally exposes the stapling assembly or the head assembly. The shield may be integral with the stapler, or provided after-market as an add-on. A surgical stapler may additionally or alternatively include an air or gas pump assembly that can be used to insufflate the rectum and intestinal tract during insertion and advancement of the stapler.

A porous substrate or implant for implantation into a human or animal body constructed from a structural material and having one or more regions which when implanted are subjected to a relatively lower mechanical loading. The region(s) are constructed with lesser mechanical strength by having a lesser amount of structural material in said region(s) relative to other regions. This is achieved by controlling pore volume fraction in the regions. A spacer is adapted to define an open-cell pore network by taking a model of the required porous structure, and creating the spacer to represent the required porous structure using three-dimensional modelling. Material to form the substrate about the spacer in infiltrated the scaffold structure formed.

An alignment system uses a self-referencing interferometer that produces two overlapping and relatively rotated images of an alignment markers. Detectors detect intensities in a pupil plane where Fourier transforms of the images are caused to interfere. The positional information is derived from the phase difference between diffraction orders of the two images which manifests as intensity variations in the interfered orders. Asymmetry can also be measured by measuring intensities at two positions either side of a diffraction order.

The present invention relates to compositions and methods for treating, characterizing, and diagnosing cancer. In particular, the present invention provides gene expression profiles associated with solid tumor stem cells, as well as novel stem cell cancer markers useful for the diagnosis, characterization, and treatment of solid tumor stem cells.

A system, including software components, that efficiently and dynamically analyzes changes to data sources, including application programs, within an integration environment and simultaneously re-codes dynamic adapters between the data sources is disclosed. The system also monitors at least two of said data sources to detect similarities within the data structures of said data sources and generates new dynamic adapters to integrate said at least two of said data sources. The system also provides real time error validation of dynamic adapters as well as performance optimization of newly created dynamic adapters that have been generated under changing environmental conditions.

A method of evaluating the driving behavior in a vehicle. The method includes determining values of a plurality of parameters of the operation of a first vehicle in a first road segment, determining values of the plurality of parameters for one or more second vehicles in a second road segment having similar properties to those of the first road segment, comparing the determined values of the first vehicle and the one or more second vehicles and providing an evaluation of the driving behavior of the first vehicle, responsive to the comparison.
