Patent number: 10135547Abstract: Embodiments of the invention are directed to control devices configured for use with computing devices. More specifically, the present invention relates to methods and devices for shortening wireless reconnection time by determining the presence of an object or body near a device. When the control device detects an object or body in proximity to the device, the control device may automatically establish a wireless connection with a host devices, such that when the control device receives any user interactions, the wireless connection has already been established, preventing loss of data.Type: GrantFiled: September 12, 2016Date of Patent: November 20, 2018Assignee: Logitech Europe S.A.Inventors: Jean-Christophe Hemes, Francesco Spina, Olivier Gay, Gilles de Preux, Olivier Bodenmann, Paolo Cremonino, Laurent Mealares

Patent number: 10114438Abstract: A chassis determines a steady state power consumption of each node in the chassis based upon real-time monitoring of power consumption of the nodes. The chassis also determines a power allocation for each node based upon the steady state power consumptions for the nodes. The chassis also determines a total power allocation for the chassis based upon the steady state power consumptions for the nodes. The chassis also determines a source and amount of input power for the chassis based upon the total power allocation for the chassis. The steady state power consumption of a node may be determined by sampling the power consumption of the node during a window period, and setting the steady state consumption of the node to a range if the values of the samples during the window period are within the assigned range.Type: GrantFiled: August 4, 2014Date of Patent: October 30, 2018Assignee: DELL PRODUCTS, LPInventors: Santosh K. Sahu, Krishna Kumar P.K., Rama B. Bisa, Tandava V. K. Popuri, Roger W. Foreman
