Patent number: 9989596Abstract: A circuit for displaying the state of a battery that is almost discharged features a battery, an inductive load, and a controllable switch connected in series. The circuit also includes a display element connected in series with the inductive load and the battery. The controllable switch is opened when a voltage of the battery is lower than a first threshold level and is only closed again when the voltage of the battery is greater than a second threshold level. The circuit may also include a control circuit having a comparator which compares the voltage of the battery with the first threshold level and the second threshold level and triggers the controllable switch accordingly.Type: GrantFiled: March 12, 2012Date of Patent: June 5, 2018Assignee: The Gillette Company LLCInventors: Torsten Klemm, Gerrit Rönneberg

Patent number: 7637014Abstract: Handles are provided for battery operated razors. In some implementations, the handles include (a) a housing including a grip portion defining a chamber having an interior wall, and a battery cover removably mounted on the grip portion, the housing being configured to contain one or more batteries, and (b) a closing system, including a first component within the battery cover, and a second component secured to the interior wall of the grip portion, the first component being configured to move axially within the battery cover during engagement of the battery cover with the grip portion, and being biased toward a predetermined axial position.Type: GrantFiled: September 6, 2005Date of Patent: December 29, 2009Assignee: The Gillette CompanyInventors: Fred Schnak, Luis Burrel, Stefan Rehbein, Gerrit Rönneberg, Uwe Schaaf

Patent number: 7628759Abstract: The invention relates to a blood pressure manometer comprising a housing, a cuff connected to the housing, a cuff storage element in which a section of the cuff can be retracted to adjust the width of the cuff, and a cuff tightener which pulls the cuff section into the cuff storage element with a pre-determined tractive force. The cuff tightener comprises a pre-tensioned spring drive and a detachable withdrawal blocking element which prevents the cuff from withdrawing counter to the spring drive. The spring drive causes the cuff to automatically tighten with a pre-determined force, ensuring reproducible measuring results. The cuff storage element and the cuff tightener can be integrated into or engaged in a locking manner with the housing. An automatic switch-on mechanism switches the appliance on as soon as the cuff storage element is locked to the housing when the cuff is positioned on the limb.Type: GrantFiled: November 30, 2004Date of Patent: December 8, 2009Assignee: Kaz USA, Inc.Inventors: Dirk Freund, Brigitte Harttmann, Ulrich Heck, Stefan Hollinger, Gerrit Ronneberg, Fred Schnak, Martin Simeth, Dieter Wunder, Siegfried Zellermayer
