Abstract: A method of attaching prosthetic implants to bone, applicable to tibia, patella, acetabulum, glenoid, or femur, includes trimming an articular surface of the bone, leaving a trimmed surface. Holes are punched or drilled into the surface in a predetermined array before polymethyl methacrylate bone cement is used to attach the surface to the implant. In an embodiment, the holes are punched by placing a punch-plate with sharpened punch spikes on the surface, and striking the punch plate to drive punches into the trimmed surface. In another embodiment, holes are drilled using a drilling template with predrilled guidance holes placed on the surface of the bone. In another embodiment, holes are drilled by positioning a robotic drill over the trimmed surface; adjusting a drilling pattern of the robotic drill according to the trimmed surface; and using the robotic drill to drill holes of predetermined depth according to the drilling pattern.

Abstract: Disclosed are various embodiments involving use of a multi-scale fiducial by an autonomously controlled aerial vehicle. A first image at a first location is captured, and a first fiducial at a first scale of a multi-scale fiducial is recognized within the first image. The autonomously controlled aerial vehicle is piloted relative to the multi-scale fiducial based at least in part on information contained within the first fiducial. A second image at a second location is captured, and a second fiducial at a second scale of the multi-scale fiducial is recognized within the second image. An action is then performed based at least in part on information contained within the second fiducial.

Abstract: Disclosed are various embodiments of a multi-scale fiducial. A multi-scale fiducial may have three or more scales, where the child fiducials are nested or otherwise linked by a relative position to the parent fiducials. Multi-scale fiducials may facilitate target identification and tracking at varying distances, potentially without the aid of a scale-invariant recognition algorithm. One application of multi-scale fiducials may involve target identification for autonomously controlled aerial vehicles.

Abstract: A processor uses a dedicated buffer to reduce the amount of time needed to execute memory copy operations. For each load instruction associated with the memory copy operation, the processor copies the load data from memory to the dedicated buffer. For each store operation associated with the memory copy operation, the processor retrieves the store data from the dedicated buffer and transfers it to memory. The dedicated buffer is separate from a register file and caches of the processor, so that each load operation associated with a memory copy operation does not have to wait for data to be loaded from memory to the register file. Similarly, each store operation associated with a memory copy operation does not have to wait for data to be transferred from the register file to memory.

Abstract: A reactive correction to chamber impedance changes without the need to change the process recipe is disclosed. The reactive correction may be done automatically and repeatedly during processing. A control of RF power application to a plasma processing chamber is performed, so as to minimize reflected power and efficiently apply the RF power to the plasma. Autotuning of the RF power application is enabled without modifying a qualified process recipe. The autotuning can be applied using frequency matching and RF matching network tuning.

Abstract: Methods and systems for push channel authentication for mobile computing devices are provided. A mobile application may be supplied, and an indication that the application has been loaded on the mobile computing device may be processed. A device identifier received from the mobile computing device through a network may be processed, and corresponding information may be stored in an authentication information repository. An authentication key and an authentication token may be generated and sent separately to the mobile computing device through a push channel and through a second channel. That the mobile application has received the authentication key and the authentication token may be verified. A notification that the mobile application has received the authentication key and the authentication token may be processed. The notification may be validated at least in part with the information corresponding to the device identifier in the authentication information repository.

Abstract: A mixed gas is separated with collection of at least one constituent gas. An inlet leads to a blower or other gas compression element through a valve. This blower feeds a chamber which contains media which selectively adsorbs the constituent gas to be collected, such as nitrogen from air. An exhaust from the chamber leads to an exhaust through a check valve. The blower can be reversed after nitrogen has been adsorbed within the chamber to desorb nitrogen and deliver nitrogen back through the blower. The inlet valve is closed after blower reversing and a separate diversion pathway is opened so that nitrogen is delivered from the blower to a nitrogen collection region. A variant system also includes an oxygen collection region on a side of the chamber opposite the blower for collection of both nitrogen and oxygen separated from air simultaneously, or collection of other constituent gases.
