8210038, Jul 3, 2012
Filed:
Feb 17, 2009
Appl. No.:
12/372335
Inventors:
Marko Rocznik - Cupertino CA, US
Assignee:
Robert Bosch GmbH - Stuttgart
International Classification:
G01C 19/56
US Classification:
7350412, 7350414
Abstract:

US Patent:
8499639, Aug 6, 2013
Filed:
Jun 21, 2010
Appl. No.:
12/819573
Inventors:
Marko Rocznik - Cupertino CA, US
Assignee:
Robert Bosch GmbH - Stuttgart
International Classification:
G01L 11/00
US Classification:
73702, 73700, 73753
Abstract:
In one embodiment, a pressure sensor assembly for use with an application specific integrated circuit includes a capacitive sensor, a sensor coil within a first sensor compartment and operatively connected to the capacitive sensor to form a sensor L-C tank circuit, a measuring oscillator including a measuring coil located within a second sensor compartment and spaced apart from the sensor coil and a feedback circuit configured to provide a control signal for the measuring oscillator based upon an output of the measuring oscillator, and a low frequency signal source configured to provide a low frequency signal to the measuring oscillator.

US Patent:
20090045966, Feb 19, 2009
Filed:
Jul 18, 2008
Appl. No.:
12/218902
Inventors:
Marko Rocznik - Palo Alto CA, US
International Classification:
G08B 23/00
US Classification:
3405737
Abstract:
A clothing arrangement or device having a sensor element for detecting a left position, which includes a housing, at least one position sensor, a chip (IC) having an integrated evaluation circuit, and a current-supply and charge unit, the position sensor being a monoaxial acceleration sensor, the current-supply and charge unit including two high-capacity capacitors, a coil and a diode, and the sensor element being coupled to an external receiver unit. Furthermore, the invention relates to the use of a clothing arrangement or device to avoid the supine hypotensive syndrome in pregnant women.

Method For Regulating An Excited Oscillation

View page
US Patent:
20100127785, May 27, 2010
Filed:
Oct 20, 2009
Appl. No.:
12/589266
Inventors:
Marko Rocznik - Cupertino CA, US
Dayo Oshinubi - Rutesheim, DE
International Classification:
H03L 5/00
US Classification:
331106
Abstract:
In a method for regulating an excited oscillation of a system to a resonance case of the system, instantaneous values of the oscillating quantity are discretely recorded using one sampling frequency, and the sampling frequency is selected to be below twice a maximum frequency of the system. In addition, the following steps are provided: ascertaining an oscillation amplitude from the instantaneous values; regulating a control amplitude on the basis of the ascertained oscillation amplitude; specifying a control frequency on the basis of the control amplitude; generating a control oscillation in consideration of the control frequency; combining the oscillation amplitude and the control oscillation to form a control signal; and exciting the system in consideration of the control signal.

Capacitive Sensor

US Patent:
20140049273, Feb 20, 2014
Filed:
Aug 15, 2012
Appl. No.:
13/586632
Inventors:
Marko Rocznik - Cupertino CA, US
Assignee:
ROBERT BOSCH GMBH - Stuttgart
International Classification:
G01R 27/26
US Classification:
324679
Abstract:
A sensor includes a variable capacitor, a fixed capacitor, an inductor, a switch that electrically connects the variable capacitor with the inductor or the fixed capacitor with the inductor, an oscillator that generates a periodic signal, and a controller connected to the switch, the oscillator, and the inductor. The controller operates the switch, identifies a frequency of a first oscillation of the variable capacitor and the inductor based on the periodic signal from the oscillator, identifies a frequency of a second oscillation of the fixed capacitor and the inductor based on the periodic signal from the oscillator, and identifies a capacitance of the variable capacitor based on a ratio of the frequency of the first oscillation to the frequency of the second oscillation.
