Filed:

Apr 2, 2001

Appl. No.:

09/821992

Inventors:

James C. Bach - Carmel IN
Kevin M. Gertiser - Noblesville IN

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

G01P 348

US Classification:

324173, 324225, 32420712, 32420717

Abstract:

An improved method of measuring vehicle speed based on the output signal of a variable reluctance speed sensor responsive to the teeth of a transmission output gear adjusts the sensitivity of a signal processing circuit in dependence on the mode of operation of the vehicle so as to reduce sensitivity to output signals produced by gear tooth vibration. The signal processing circuit only passes portions of the sensor output signal that have an amplitude greater than a predefined threshold and a frequency less than a predefined frequency, except when an electronic controller identifies a condition of potentially erroneous speed sensing characterized by substantially stationary vehicle operation with the engine decoupled from the output gear and an engine speed in excess of a calibrated threshold. Under the identified condition, the controller reduces the sensitivity of the signal processing circuit by raising the predefined amplitude threshold and lowering the predefined cut-off filter frequency so that only large amplitude, low frequency signals are passed.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

G01P 348

US Classification:

324166, 324173, 32420712

Abstract:

A variable reluctance sensor interface module having a variable attenuation circuit and a rectifier and differential to single-ended conversion circuit for operating in a current mode to attenuate a differential input voltage. The variable attenuation circuit receives an input differential voltage from a magnetic sensor, converts the differential voltage to current, and variably attenuates the current. The rectifier and differential to single-ended conversion circuit converts the variably attenuated current to a voltage output. The input circuit includes an RC filter that attenuates high frequency signals. An initial threshold circuit generates an initial threshold voltage that compensates for internal resistance variations.

Appl. No.:

12/938670

Inventors:

James Carter Bach - Seymour IN, US
Paul Bryan Cadima - Prospect KY, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

G08B 21/00

US Classification:

340605, 340521, 340506, 34087002, 34087007, 73 40, 73 491, 73 494, 126 52, 126 39 BA, 126 39 C, 126 39 E

Abstract:

A method and apparatus for determining whether an appliance is leaking gas is provided. Pressure measurements are taken after closing off the flow of gas to the appliance and within the appliance so as to isolate the gas within the distribution system of the appliance. If unacceptable changes in the pressure of the gas are detected, a warning signal can be provided and the flow of gas into the appliance can be maintained in an off state until further corrective steps are undertaken. Corrections for temperatures changes between pressure measurements can also be provided.

Assignee:

General Electric Company - Schenectady NY

International Classification:

G08B 17/10
A47J 37/00

US Classification:

340634, 1263881

Abstract:

A method and apparatus are provided for determining which heating element on a cooking appliance is associated with a particular heating element control. More particularly, when a user of the appliance touches a control on the cooking appliance and/or comes in close proximity to such control, a visual identification of which heating element is associated with such control is provided. The visual identification can be e. g. , a light that illuminates the associated heating element or a visible display that otherwise indicates the associated heating element.

Inventors:

James Carter Bach - Seymour IN, US

Assignee:

GENERAL ELECTRIC COMPANY - Schenectady NY

International Classification:

H05B 3/68

US Classification:

21944811

Abstract:

A method and apparatus for monitoring the temperature of a cook top is provided. Overhead sensors are used for temperature sensing of a heating element, cooking utensil, and/or food located on the cook top. The resulting temperature information is then communicated to the cook top. Features associated with use of the temperature information such as various notifications to the operator and/or regulation of the heating elements can be also provided.

Inventors:

James Carter Bach - Seymour IN, US

International Classification:

G01F 1/688
F24B 5/02

US Classification:

7320423, 126 15 A

Abstract:

Apparatus and methods are disclosed to measure airflow within a chassis-cooling pathway of an appliance. The rate of airflow is determined based on the differential heating among a pair of sensor devices, such as thermistors, transistors, diodes or resistive thermal devices operating at distinctly different power levels. The appliance utilizes the calculated airflow rate to perform safety-related tasks, such as de-energizing heating elements when low or no airflow is detected.

Abstract:

A damper system for an exhaust vent of a gas operated oven includes a temperature-reactive member configured to expand when actuated by heating to a pre-determined temperature, and a damper member coupled to the temperature-reactive member, the damper member configured to move with the expansion of the temperature-reactive member to control a size of an opening to the exhaust vent from the gas operated oven.

International Classification:

F24F 11/00

US Classification:

454256

Abstract:

A device for detecting and/or measuring air flow in a cooling air flow passageway of an appliance using solid-state flow detectors. Heat generating components of the appliance are controlled in response to detected air flow. More specifically, the disclosure provides a device for detecting the presence of airflow and/or the approximate rate of airflow in a cooling channel of an appliance chassis. Based on this information, the appliance can perform safety-related tasks, such as de-energizing associated heating elements if there is too-low (or no) airflow detected. The solid-state flow detectors are easily fabricated, installed, and calibrated and avoids the calibration, fabrication and/or installation difficulties associated with sail switches and other such approaches such as thermal limit switches.
