Capacitive Drop Power Supply With Low Power Consumption

View page
US Patent:
7196918, Mar 27, 2007
Filed:
Sep 8, 2004
Appl. No.:
10/936002
Inventors:
Mike A. Steffen - Rockford IL, US
Gregory A. Peterson - South Barrington IL, US
Jurgis Astrauskas - Saint Charles IL, US
Assignee:
Emerson Electric Co. - St. Louis MO
International Classification:
H02M 7/10
US Classification:
363 49, 363 52, 363908
Abstract:
An improved capacitive drop power supply is provided for use in home appliances. The power supply circuit includes: a rectifier for converting an AC power source to a DC voltage; a current limiting capacitance interposed between the AC power source and the rectifier; a low voltage output stage and a higher voltage output stage. The low voltage output stage supplies DC voltage from the rectifier to a microcontroller residing in the home appliance. The higher voltage output stage is connected in series with the low voltage stage and supplies DC voltage to the higher voltage loads associated with the home appliance. To reduce power consumption, a shunt circuit path is connected in parallel across the higher voltage output stage which causes a phase shift in the AC power signal and thereby reduce real power consumption when a no load condition is placed on the output stage (e. g. , during a standby operating condition of the home appliance).

Method And Apparatus For Operating An Optical Receiver For Low Intensity Optical Communication In A High Speed Mode

View page
US Patent:
7280769, Oct 9, 2007
Filed:
Jul 28, 2003
Appl. No.:
10/628203
Inventors:
Jurgis Astrauskas - Saint Charles IL, US
Assignee:
Emerson Electric Co. - St. Louis MO
International Classification:
H04B 10/06
US Classification:
398202, 398164, 398207
Abstract:
An optical communication probe enables a diagnostic tool to optically communicate with an external device, such as an appliance, through a low intensity indicator light of the external device. The communication probe includes an optical transmitter, an optical receiver, and a voltage converter for converting a first voltage signal received from the diagnostic tool to a second voltage signal. The second voltage signal is coupled to the optical receiver to operate the optical receiver in a high speed mode.

Method And Apparatus For Conserving Battery For Operation Of A Low Intensity Optical Communication Probe

View page
US Patent:
7315148, Jan 1, 2008
Filed:
Jul 28, 2003
Appl. No.:
10/628700
Inventors:
Jurgis Astrauskas - Saint Charles IL, US
Gregory A. Peterson - South Barrington IL, US
Assignee:
Emerson Electric Co. - St. Louis MO
International Classification:
H01M 10/44
H01M 10/46
US Classification:
320114
Abstract:
An optical communication probe enables a diagnostic tool to optically communicate with an external device, such as an appliance, through a low intensity indicator light of the external device. The communication probe is powered by a battery that is selectively coupled to the communication probe through a switch. The switch is coupled to a diagnostic tool to receive a power status signal from the diagnostic tool. In response to the power status signal indicating user inactivity at the diagnostic tool, the switch de-couples the battery from the communication probe to conserve battery life.

Method And Apparatus For Improving Noise Immunity For Low Intensity Optical Communication

View page
US Patent:
7321732, Jan 22, 2008
Filed:
Jul 28, 2003
Appl. No.:
10/628765
Inventors:
Jurgis Astrauskas - Saint Charles IL, US
Assignee:
Emerson Electric Co. - St. Louis MO
International Classification:
H04B 10/00
US Classification:
398138, 398130, 398164
Abstract:
An optical communication probe enables a diagnostic tool to optically communicate with an external device, such as an appliance, through a low intensity indicator light of the external device. The communication probe includes an optical transmitter, an optical receiver, and a housing in which the optical transmitter and optical receiver are mounted. The optical transmitter transmits light signals having a logical polarity that is the opposite of an indicator light associated with an indicator light of an external device with which the optical transmitter is communicating. Use of the opposite logical polarity improves the noise immunity for the optical communication between the communication probe and the external device.

Method And Apparatus For Independent Control Of Low Intensity Indicators Used For Optical Communication In An Appliance

View page
US Patent:
20050024330, Feb 3, 2005
Filed:
Jul 28, 2003
Appl. No.:
10/628202
Inventors:
Jurgis Astrauskas - Saint Charles IL, US
International Classification:
G09G005/08
US Classification:
345158000
Abstract:
Indicator lights of an appliance are used for optical communication with a diagnostic tool through a communication probe. The indicator lights of the appliance are arranged in at least two groups. One indicator light is selected from one group of indicator lights to operate as an optical transmitter and another indicator light is selected from the other group of indicator lights to operate as an optical receiver. Preferably, the two selected indicator lights are in proximity to one another so the communication probe for the diagnostic tool may be more compactly designed.

Method And Apparatus For Using A Close Proximity Probe For Optical Communication With A Device External To The Probe

View page
US Patent:
20050025493, Feb 3, 2005
Filed:
Jul 28, 2003
Appl. No.:
10/628226
Inventors:
Jurgis Astrauskas - Saint Charles IL, US
International Classification:
H04B010/00
US Classification:
398140000
Abstract:
An optical communication probe enables a diagnostic tool to optically communicate with an external device, such as an appliance, through a low intensity indicator light of the external device. The communication probe includes an optical transmitter and an optical receiver mounted within a housing. The optical transmitter is a high intensity light emitting diode (LED) and the optical receiver is a sensitive phototransistor. The high intensity LED helps compensate for the relatively high optical threshold of a standard photodetector or LED used as an optical receiver at the appliance and the sensitive phototransistor helps compensate for the relatively low intensity light generated by the indicator light of an appliance.

System And Method To Detect Child Presence Using Active Mems Sensors

View page
US Patent:
20120235514, Sep 20, 2012
Filed:
Apr 23, 2012
Appl. No.:
13/453830
Inventors:
Jurgis Astrauskas - St Charles IL, US
Assignee:
STMicroelectronics, Inc. - Carrollton TX
International Classification:
H02H 11/00
US Classification:
307326
Abstract:
The presence of a child within an enclosed space in an appliance, such as a washing machine, dishwasher or refrigerator, is detected using one or more MEMS sensors positioned to detect movement within the enclosed space through various measured characteristics. In preference, combinations of different types of MEMS sensors are utilized to detect the movement. Movement may be attributed to the presence of a child inside the enclosed space, rather than resulting from other influences, with increased reliability if the determination is made based upon such combinations of different characteristics. Safety processes may be initiated upon detecting the presence of the child.

System And Method For Optically Isolated Current Or Voltage Sensing

View page
US Patent:
20190113570, Apr 18, 2019
Filed:
Oct 17, 2017
Appl. No.:
15/785960
Inventors:
- Irvine CA, US
Jurgis ASTRAUSKAS - St. Charles IL, US
International Classification:
G01R 31/317
G01R 19/32
G01R 19/25
H02H 9/04
Abstract:
A system and method for monitoring, testing or configuring electrical devices includes an input amplifier having an input connected to a device load line to generate an output linearly proportional to a voltage on the load line. An output of the input amplifier is connected to a photodiode in an optical path with a phototransistor. The phototransistor generates an output proportional to light generated by the photodiode, and this output is amplified and passed to an analog-to-digital converter. The converter generates a digital voltage level corresponding to the amplified output of the phototransistor. Digital temperature information is used to further enhance linearity of a generated digital voltage level. Multiple quantum well photodiodes further improve measurement linearity.
