US Patent:

6963040, Nov 8, 2005

Filed:

Dec 6, 2004

Appl. No.:

10/892596

Inventors:

Robert Urman - Schaumburg IL, US

Assignee:

Westinghouse Air Brake Technologies Corporation - Wilmerding PA

International Classification:

H01H009/00

US Classification:

200310, 200314

Abstract:

An illuminated touch switch has a touch sensitive area and a plurality of light emitting diodes arranged in a predetermined pattern. The touch switch includes a first rigid circuit board with a first electrical conductor and a second flexible circuit board with a second electrical conductor separated by a spacer of a predetermined thickness. Both conductors are aligned with the touch sensitive area and are coupled from the applied pressure providing an output signal. Light emitting diodes illuminate a single color light to indicate an enabled condition of the touch sensitive area.

Assignee:

Wabtec Holding Corp. - Wilmerding PA

International Classification:

H03K 17/975

US Classification:

200600, 200510, 250221, 345173

Abstract:

A capacitance based switch device employs an electric field imaging device electrically coupled via an electrical conductor to a conductive electrode member that is attached to the door or any other suitable surface. Such electric field imaging device generates a sine wave which is transmitted to the conductive electrode member and produces a surrounding electrical field. Any human body part which enters such electrical field will create a capacitance load due to the body being grounded to a surface. Reduction in distance between the body part and the conductive electrode will increase the capacitance and will decrease the voltage intermediate the resistor and conductive electrode which is an inverse function of the capacitance. Such change in voltage will be detected by a microcontroller by comparing voltages at each end of the resistor and the change exceeding a predetermined threshold will be associated with an output control signal.

International Classification:

G06G 7/48
E05F 15/02
G06F 17/10

US Classification:

701124, 49 31, 49502, 49503, 307 101

Abstract:

An apparatus and method for measuring a directional attitude of a driven load in respect to a level plane is employed to adjust initial driving power requirements in order to overcome the effects of such attitude. The apparatus employs a sensor for measuring the attitude, a processor for comparing the measurement against a threshold and a driver for altering the initial driving power requirements. Additional sensors for measuring shock, vibration, and temperature levels that the load is subjected to prior to the movement may be employed for calibration of the directional attitude measuring sensor or for further adjustment of the initial driving power requirements.

Appl. No.:

11/817353

Inventors:

Robert Urman - Schaumburg IL, US

Assignee:

Wabtec Holding Corp. - Wilmerding PA

International Classification:

H01H 9/54

US Classification:

307139

Abstract:

A passenger door open request switch for use in a multi-passenger, mass-transit vehicle. A wireless, powerless switch sensor which includes an RFID reader, a circuit located remotely from the RFID reader that is formed by connecting an RFID antenna with a control/storage element, and a switch. The switch is connected between the antenna and the storage element in such a way as to either enable or disable the antenna. This allows the system to be configured to monitor the status of the switch.

Abstract:

A method and apparatus of recognizing the presence of a passenger in front of a door of a transit vehicle comprises directing an ultrasound transmitter/receiver at a volume of space adjacent the door, emitting an ultrasound pulse into the empty volume, recording and integrating intensity of the echoes and storing the integrated value as a standard value, repeatedly emitting an ultrasound pulse into the volume, and comparing the integrated values to the standard value.

International Classification:

G01F 142
A61B 508

US Classification:

7386161

Abstract:

A flow device is provided for sensing air flow and includes a body having at the opposite ends thereof coaxial bores. Counterbores extend inwardly from the coaxial bores and are interconnected by a restricted bore having lateral bores extending from opposite ends thereof to provide a pneumatic pressure drop. The bottom portions of the respective counterbores are relieved to provide a pair of troughs for water collection outside of the normal air flow area so that water can accumulate for an extended period of time before interferring with pressure drop readings.
