摘要:
A method and device for teaching foreign languages is disclosed. The device can have an interactive user interface so that a language student can choose what percent of language in a passage is presented in the student's native language and what percent is presented in the language the student wishes to learn. The passage may be presented as audio or may be presented in visual form.

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.

A new and distinct Grevillea hybrid cultivar named ‘RR01’ which is characterized by a very prostrate growth habit with a vigorous growth rate, dark green pinnatisect foliage with red immature branches, racemose inflorescence typical of the species with approximately 30 to 50 florets, and the stability of these characteristics from generation to generation.
摘要:
Disclosed herein is a method for producing an evolvable tissue model of a patient and, using this model, modelling physical transformations of the tissue (e.g. deformation) of the tissue model by interacting the tissue model with influence models which model interactions with the tissue such as surgical instruments, pressure, swelling, temperature changes etc. The model is produced from a set of input data of the tissue which includes directional information of the tissue. The directional information is used to produce an oriented tissue map. A tissue model is then produced from the oriented tissue map such that the tissue model reflects the directionality of the tissue component. When the tissue model is subjected to an influence that causes tissue deformation over a period of time, the tissue model directionally deforms over the period of time in a manner which reflects a trajectory of the influence interacting with the directionality of the tissue component.
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.
摘要:
Disclosed herein is navigation and simulation systems and methods for minimally invasive therapy in which the navigation system imports a planning method using patient specific pre-operative images. The navigation system uses intraoperative imaging during the medical procedure to update the preoperative images and provides images of tracked surgical tools along the surgical path prepared from the preoperative images.
摘要:
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.
摘要:
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.
