Title: Powering a surgical robot arm
Inventor: Gordon Thomas Deane
IPC: A61B34/30
Filed: 2020-04-24
Abstract: A control system for a surgical robot. The robot comprises: a multi-jointed arm extending from a base to a terminal end with attachment to a surgical instrument; and a surgeon console with an input device. The arm is operable in: a full power mode 601, where the joints are powered by a first power source; and a reduced power mode, where the joints are powered by a second power source. In full power-mode, the control-system controls the arm in a surgical mode 602 by converting input device movements to control signals for moving the arm’s joints and should a first-power-source power failure be detected 603, the control-system enables the reduced power mode 604 and transitions from surgical-mode to an arm lock mode by sending signals to lock the arm joints. When in the reduced power mode, the control-system responds to detecting a cessation of the power failure 606 by disabling the reduced power mode, re-enabling the full power mode, and returning control back to the surgical-mode. Preferably, in response to power failure cessation, the control-system will only return control of the arm to surgical-mode when the second power source has a battery capacity above a threshold value 701.

Historical product and location data may include point-of-sale (POS) data, sales data, inventory data, promotional campaign data, weather information, event information, holiday information, web traffic, social media information, or market indices. At least one feature associated with the historical data is subject to feature engineering. In response to a request to forecast product sales at a location 1002, a forecasting method is selected comprising either selecting a machine learning model, retraining a previously-selected machine learning model, or using a previously-selected machine learning model. The historical data are analysed using the selected method to produce the requested forecast of product sales at the location. If this is the first time a request has been made for a particular product and location 1004, then a machine learning model is selected by training multiple models and selecting the most accurate 1006. If a similar request has previously been made, then an existing machine-learning model is selected and may be retrained if sufficient time has passed 1014, new data have become available 1008, 1010, or accuracy has dropped 1012.

Acoustic effects may be applied to the speech signal based on the virtual surroundings. The invention provides techniques for intelligently positioning speech in a virtual environment. Factors such as user preferences, the location of virtual environment audio and/or visual events, avatar location, and others can be taken into account when selecting a suitable location for the speech. The virtual environment can be a game environment, a meeting environment, an augmented reality environment, a virtual reality environment, and the like.
