摘要:
Disclosed herein is a system and method for dynamic validation, correction of registration for surgical navigation during medical procedures on a patient which involves confirmation of registration between one or more previously registered virtual objects, such as surgical tools etc. in a common coordinate frame of a surgical navigation system and an operating room, and intra-operatively acquired imaging during the medical procedure in the common coordinate frame. The method includes displaying intra-operatively acquired imaging of the surgical field containing the one or more real objects corresponding to the one or more previously registered virtual objects, with the real objects being tracked by a tracking system. The method overlaying a virtual image containing the previously registered virtual objects onto the intra-operatively acquired imaging, from the point of view of the intra-operatively acquired imaging, and detecting for any misalignment between any one of the one or more previously registered virtual objects contained in the virtual image and its corresponding real object contained in the intra-operatively acquired imaging.

A medical navigation system is provided. The medical navigation system includes a computing device having a processor coupled to a memory, a wireless communication component and a display for displaying an image. The medical navigation system further includes a sensor module attached to a medical device. The sensor module includes a housing for housing components of the sensor module and for attaching to the medical device, a processor housed in the housing, a memory coupled to the processor, a wireless communication component coupled to the processor, a battery coupled to the processor, and a sensor coupled to the processor. The sensor generates a signal to be transmitted wirelessly via the sensor module wireless communication component and receivable by the computing device wireless communication component, the signal representing movement of the medical device.

An array of photovoltaic assemblies places photovoltaic panels in spaced rows. The array has a number of supports, each support including: (a) a first member with an upper support surface for supporting the neighboring side edges of an adjacent pair of photovoltaic panels located in one of the rows; (b) a second member with a lower support surface disposed at an acute angle relative to the upper support surface, and connecting to the first member at a front joint; and (c) a third member spaced from the front joint and connected between the first and the second member. At least one front tray is disposed next to the front edge of photovoltaic panels in front. A number of back trays and a number of inclined deflector sections are arranged together in a plurality of ranks. These ranks are interleaved with the spaced rows of photovoltaic panels. The back trays in each of the ranks are aligned. The inclined deflector sections extend up to the back edge of a corresponding one of said photovoltaic panels.

A medical navigation system is provided, comprising a computing device having a processor coupled to a memory, a tracking camera for tracking medical devices, and a display for displaying an image; an automated arm assembly electrically coupled to be computing device and controlled by a signal provided by the computing device, the automated arm assembly including a multi-joint arm having a distal end connectable to an effector that supports a surgical camera electrically coupled to the computing device; and a medical device having a tracking marker attachable to the medical device. The computing device is configured to position the automated arm assembly, based on an input command, in response to a position in space of the medical device such that a surgical site of interest remains within a field of view of the surgical camera, the position in space of the medical device determined by the computing device based on a signal provided to the computing device by the tracking camera; and display on the display an image provided by an image signal generated by the surgical camera.

Easy to use, cost-effective methods and devices for evaluating and treating stress and thereby disorders caused or exacerbated by stress are provided. More particularly methods and devices for identifying RSA waves during respiration which provide a subject with real-time RSA wave information are provided. These methods and devices also can be used to identify drop points in RSA waves. Such methods and devices provide subjects with the ability to maintain parasympathetic outflow and thereby prevent and/or reduce levels of stress.

A microcontroller unit (MCU) includes a CPU, a system integration module (SIM), and a memory. The CPU decodes instructions to determine the function, an addressing type and an operand address, and converts the operand address to a first address. The SIM converts the first address to a memory address. The memory has a first section addressable via a tiny addressing mode and a second section addressable via a short addressing mode. The tiny and short address spaces can be addressed by a single instruction word. The remaining memory locations can be accessed via alternative addressing modes, such as indirect addressing and paging. The first and second memory sections include mapped registers for indirect addressing, index addressing and paging.

The present invention is a variant of traditional Twenty-One in which the dealer and players attempt to build a hand with a value of twenty-one, or as close to twenty-one as possible without exceeding twenty-one, using cards that are known to players and the dealer as they are dealt and shared cards that remain unknown until all player and/or dealer decisions are completed.

A paintball marker has a firing mechanism with at least a bolt, spool poppet valve, and vent. The bolt is slidable within a firing chamber and has a channel therethrough, The spool poppet valve has a large cross section portion and a smaller cross section portion, the larger cross section portion providing a seal against the bolt's channel. The smaller cross sectional portion has an O-ring that separates a channel, in which the spool poppet valve is slidably movable, into a front portion and a rear portion. Compressed gas enters the spool poppet valve's channel, in both the spool poppet valve's separated front and rear portions, and pushes the spool poppet valve towards the bolt, which in turn moves with the spool poppet valve. Finally, a vent through which the spool poppet valve channel's rear portion can vent to atmosphere, and upon such venting, the compressed gas in the spool poppet valve channel's front chamber drives the spool poppet valve away from the bolt, breaking the seal between the spool poppet valve and the bolt's channel, and compressed gas in the spool poppet valve channel's front portion and compressed gas in the firing chamber exits through the bolt's channel to drive a paintball from the marker.
