Patent number: 10292581Abstract: A display device with a retaining device is disclosed, which can be placed on the head of a user. The display device contains a first image generator, which is secured or can be secured to the retaining device, and a first optical imaging system which is secured to the retaining device and which is designed to image an image generated on a first image plane (E) by the first image generator such that the user can perceive the image with a first eye (LA) when the retaining device is placed on the head of the user. The retaining device supports a first refraction determining optical system which is designed to determine the subjective refraction of the first eye (LA) when the retaining device is placed on the head of the user and/or the first optical imaging system is configured to be variable.Type: GrantFiled: March 18, 2017Date of Patent: May 21, 2019Assignees: Carl Zeiss Vision International GmbH, Carl Zeiss AGInventors: Manfred Arnold, Marion Kupfer, Martin Brandl, Michael Stefan Rill, Johannes Kindt, Karsten Lindig, Jesús-Miguel Cabeza-Guillén

Patent number: 10247187Abstract: A variable displacement vane pump has a control slide displaceable within its housing and a first control chamber and a second control chamber for receiving pressurized lubricant. A thermally adjustable control valve is provided in the housing for adjusting pump displacement based on a temperature of the lubricant. In addition to fluid communication channels in the control chambers, at least one vent port is provided in the second chamber. The control valve is configured to control pressure and fluid communication between the chambers along with the control slide. The control valve can help reduce pump displacement at lower temperatures and low engine speeds. At lower temperatures, the second control chamber can be pressurized by the first control chamber. At higher temperatures, the second control chamber can be vented through the control valve and/or the vent port, despite the position of the control slide.Type: GrantFiled: September 22, 2017Date of Patent: April 2, 2019Assignee: STACKPOLE INTERNATIONAL ENGINEERED PRODUCTS, LTD.Inventors: Manfred Arnold, Hans Peter Kutzer, Ralph Valkenberg
