Patent number: 10816422Abstract: A pressure sensor comprises a first substrate and a cap attached to the first substrate. The cap includes a processing circuit, a cavity and a deformable membrane separating the cavity and a port open to an outside of the pressure sensor. Sensing means are provided for converting a response of the deformable membrane to pressure at the port into a signal capable of being processed by the processing circuit. The cap is attached to the first substrate such that the deformable membrane faces the first substrate and such that a gap is provided between the deformable membrane and the first substrate which gap contributes to the port. The first substrate comprises a support portion the cap is attached to, a contact portion for electrically connecting the pressure sensor to an external device, and one or more suspension elements for suspending the support portion from the contact portion.Type: GrantFiled: February 24, 2017Date of Patent: October 27, 2020Assignee: InvenSense, Inc.Inventors: Chung-Hsien Lin, Rene Hummel, Ulrich Bartsch, Marion Hermersdorf, Tsung Lin Tang, Wang Shen Su, Chia Min Lin

Patent number: 8355758Abstract: For supporting a switch between different service modes of some service, it is determined whether a wireless communication node is stationary by evaluating changes in information about peer wireless communication nodes detected by the wireless communication node. The result of the determination is then used as a decision criterion whether to switch the service to one of at least two modes.Type: GrantFiled: October 12, 2007Date of Patent: January 15, 2013Assignee: Nokia CorporationInventors: Lauri Wirola, Marion Hermersdorf

Publication number: 20090262673Abstract: Embodiments enable using the inactive time when a mobile device is not moving to change its mode to a new state or condition of performing as if it were an access point. The embodiments can include determining if a wireless device is stationary, changing an operating mode of the wireless device from mobile mode to access point mode, and determining a current location for the wireless device with respect to a plurality of wireless access point devices. Thereafter, the embodiments can include providing stationary location services with the wireless device to other mobile wireless devices. Later, the embodiments can include detecting that the wireless device is no longer stationary; and changing the operating mode of the wireless device from access point mode to mobile mode.Type: ApplicationFiled: April 21, 2008Publication date: October 22, 2009Applicant: NOKIA CORPORATIONInventor: Marion HERMERSDORF

Publication number: 20090042565Abstract: A system for automatically controlling the scanning frequency of a radio based positioning application in a wireless communication device (WCD) based on the connection point information of the WCD. The connection point information may be utilized to identify if the WCD is near a positioning-enabled environment. Scanning may be activated, or the scanning frequency may be increased, when the WCD is in an environment that is served by certain connection points (e.g., connection points located in a city). On the other hand, when the WCD is in an environment that is not served by certain connection points (e.g., a rural area), scanning may be stopped or the scanning frequency may be reduced to conserve power in the mobile device.Type: ApplicationFiled: August 9, 2007Publication date: February 12, 2009Applicant: NOKIA CORPORATIONInventors: Marion Hermersdorf, Antti Virolainen
