Medical Device Tracking Guidance For Industry And FDA Staff March 2025
FDA is issuing this steering to announce that each the list of gadgets topic to medical machine tracking requirements, and the listing of medical devices released from monitoring requirements, itagpro bluetooth have been up to date. This up to date steerage identifies all affected devices (these tracked and people released from monitoring) in table format. The table contains two fields to explain every machine: (1) product code (procode) and (2) the standardized procode definition (product code - preferred term). These two descriptive fields are meant to provide readability about which gadgets are tracked. The product code and ItagPro preferred title are typically discovered in the approval or clearance letter issued by CDRH. FDA's steering paperwork, itagpro bluetooth together with this steerage, don't establish legally enforceable tasks. Instead, guidances describe the Agency's current considering on a topic and needs to be viewed only as recommendations, until particular regulatory or statutory necessities are cited. Using the phrase should in Agency guidances implies that one thing is prompt or advisable, but not required.
The invention pertains to a big-angle clever solar tracker, which features a moving platform and a set platform, ItagPro and a first department chain I, a second department chain II, a 3rd department chain III, and a fourth department chain are installed between the shifting platform and the fixed platform. IV, anti-loss gadget the first department I and the third department III have the same structure and are symmetrically organized, and itagpro bluetooth the second department II and the fourth branch IV have the same construction and are symmetrically organized; the first branch I includes the primary connecting rod, and the first connecting rod The upper end of the rod is related with the shifting platform by the ball pair, the lower finish of the first connecting rod is related with the primary Hooke hinge, and the first Hooke hinge is connected with the fastened platform by means of the primary connecting block by the first shifting pair; the second branch chain II Including the second connecting rod, the upper finish of the second connecting rod is related with the transferring platform by the second Hooke hinge, the decrease finish of the second connecting rod is connected with the second connecting block through the rotating pair, and the second connecting block and the fixed platform are moved via the second Secondary connection.
The 4 branch chains of the current invention kind a space parallel closed-loop construction with the transferring platform and the fastened platform, which might realize two-dimensional translation and two-dimensional rotational movement in space. 本发明属于并联机器人领域,特别涉及一种应用于定位、气象、雷达等环境下能够实现精确跟踪的四自由度单平台大转角智能太阳追踪器。 The invention belongs to the field of parallel robots, and in particular relates to a four-degree-of-freedom single-platform massive-rotation-angle intelligent sun tracker that can notice exact tracking in environments equivalent to positioning, portable tracking tag meteorology, and radar. 并联机构通常由动平台、静平台及两平台之间的若干支链组成,具有刚度大、速度快、精度高的优点,在工业机器人、运动模拟器、并联机床等领域得到广泛应用。
近些年,国外已将陆续将部分机构构型应用于工业生产中(如:delta机构),而国内则较少,而且很少应用在生产生活中。 The parallel mechanism is normally composed of a dynamic platform, a static platform and a number of other department chains between the 2 platforms. It has some great benefits of excessive rigidity, quick velocity and excessive precision. It is broadly used in industrial robots, movement simulators, parallel machine instruments and other fields. In recent times, overseas international locations have successively applied some mechanism configurations to industrial manufacturing (resembling: delta mechanism), while there are fewer domestic ones, and they're rarely utilized in production and life. 在运动模拟器、姿态调平、太阳能追踪以及并联机床等领域,通常需要实现大位移、大转角,实现较大工作空间范围内的运动。
Within the fields of motion simulators, attitude leveling, photo voltaic monitoring, ItagPro and parallel machine instruments, it's normally mandatory to attain massive displacements, massive rotation angles, and motions inside a big working space. 国内太阳能发电普遍采用固定式太阳能电池安装方式,尽管这种安装方式结构简单、成本较低,但是无法精确跟踪太阳位置,光能转换效率较低。 现有研究中,也存在部分运动型太阳能机构,单轴或双轴等多为串联机构精度不高。 其中双轴的跟踪精度相对较高,太阳板能达到的转换效率相对较大,但遇到恶劣天气难以保证装置的安全性。
