  • Patent number: 12232761
    Abstract: A handheld rotary medical device with a shaver configured to remove cartilage is disclosed. The handheld rotary medical device may include an inner drive shaft, an elongated, tubular, outer housing encapsulating the inner drive shaft such that the inner drive shaft is positioned within the outer housing and a shaver at a distal end of the inner drive shaft. The shaver may include a plurality of teeth extending radially outward from an outer surface of the inner drive shaft. The medical device may include slots or grooves in the outer housing useful for cleaning the tissue from the teeth of the shaver.

  • Publication number: 20240180075
    Abstract: The present invention provides an electric tool comprising a body, an operating component, an output shaft, and a stop mechanism. An arresting disc is disposed on the output shaft, and a groove is formed on the arresting disc; the stop mechanism comprises a protrusion, for example, a pin, which is operable so that the protrusion extends to insert into the groove to lock the output shaft. A stop mechanism of the present invention is easy to operate, delivers good safety performance, and has a relatively simple structure, which allows convenient production and subsequent maintenance. Further, a stop mechanism of the present invention automatically springs back to a non-stop position at which it detaches from the output shaft or the transmission gear of the transmission mechanism when the external force is lost, which prevents possible damage to the output shaft or transmission mechanism when a user starts the electric tool before releasing the stop mechanism.

  • Patent number: 10128658
    Abstract: Autonomous, self-adjusting, and distributed line flow processing for a network having nodes with branches coupling adjacent ones of the nodes and components coupled to the nodes. Systems, methods, and software made in accordance with this disclosure can be used to identify where power flows can exceed the maximum transfer limit in each line and to enable automated adjustments in order to avoid such conditions. These can be useful tools for both system operators of large electrical networks and for implementing automated schemes to ensure network feasibility in micro-grids or other networks with many smart components embedded with communications and/or computation capabilities.

  • Patent number: 9829992
    Abstract: Methods and devices are provided that employ multi-function keys to present a preview of potential actions to be taken by user key presses. The input device includes a plurality of key assemblies having a touch sensitive surface. The processing system can sense when one or more respective key assemblies have been contacted or pressed by the object. When the one or more respective key assemblies has been contacted by the object, an indication of a potential action taken in the program is provided to the user. The method determines whether the one or more respective key assemblies have been contacted or pressed by an object. A potential action to be taken is determined and an indication of the potential action is provided.

  • Patent number: 9054531
    Abstract: The present disclosure relates to distributed line flow processing for a network having nodes with branches coupling adjacent ones of the nodes and components coupled to the nodes. In one embodiment, the disclosed process includes receiving an objective function having component variables, nodal output variables and branch flow variables for the network. Next, the component variables, nodal output variables and branch flow variables are initialized with initial values, and then values for the branch flow variables are calculated using a distributed Newton method. Finally, values for the component variables and the nodal output variables are calculated using values calculated for the branch flow variables until the values of the component variables, the nodal output variables, and the branch flow variables converge within a predetermined threshold range.
