Publication number: 20230358573Abstract: Fiber-optic equipment is often deployed in various locations, and performance of fiber-optic transmissions may be monitored as a gauge of equipment status to prevent costly and inconvenient communication outages. Events that damage equipment that eventually result in outage and may be desirable to address proactively, but the occurrence of such events may be difficult to detect only through equipment performance. Presented herein are techniques for monitoring and maintaining fiber-optic equipment performance via enclosure sensors that measure physical properties within a fiber-optic equipment enclosure, such as temperature, pressure, light, motion, vibration, and moisture, which are often diagnostic and predictive of causes of eventual communication outages, such as temperature-induced cable loss (TICL), incomplete flash-testing during installation, exposure to hazardous environmental conditions, and tampering.Type: ApplicationFiled: July 18, 2023Publication date: November 9, 2023Inventors: Daniel Joseph LEVAC, Adam Michael DEEL, Randy Gene CLOUD, David Anthony KOEHLER, Jaanki Kirit THAKKAR, Benjamin Franklin CIESIELCZYK

Patent number: 9069030Abstract: Various embodiments for determining a voltage rating of a solenoid in an electropneumatic valve are disclosed. A braking system controller comprises a power switch electrically connected to an associated first solenoid. The power switch provides a low current regulated voltage to the associated first solenoid. The current through the solenoid is converted to a voltage. The voltage is compared to a predetermined voltage range to determine the voltage rating of the associated first solenoid. In another embodiment, the control logic is capable of determining the voltage rating of multiple solenoids in each of the electropneumatic valves connected to the controller.Type: GrantFiled: November 12, 2013Date of Patent: June 30, 2015Assignee: Bendix Commercial Vehicle Systems LLCInventors: Daniel P. Zula, Kirit A. Thakkar, Thomas J. Weed, Julie A. Miller

Patent number: 8818673Abstract: When detecting unacceptably large airgaps between wheel speed sensors and their exciter rings on wheel ends of a vehicle, wheel speed sensor output is filtered and monitored to detect signal amplitudes that correspond to the airgaps. When signal peak amplitude below a predetermined threshold is detected, the airgap is too large. Wheel ends having unacceptably large air gaps are indicated to the driver or technician via blink sequences (e.g., on an electronic stability program (ESP) indicator light or other suitable indicator), wherein each wheel end is associated with a unique blink sequence.Type: GrantFiled: March 28, 2013Date of Patent: August 26, 2014Assignee: Bendix Commercial Vehicle Systems LLCInventors: Timothy J. Frashure, Thomas J. Weed, Craig S. Haehn, Kirit A. Thakkar, Julie A. Miller, Daniel P. Zula

Patent number: 7251549Abstract: A receiver capable of receiving a remote vehicle stop request signal is mounted to a commercial vehicle and connected to the vehicle antilock braking ECU by a vehicle communication bus. The receiver may also be capable of transmitting a signal, thereby allowing the desired vehicle to be isolated. Furthermore, a user input device may be mounted to the vehicle that allows manual input of a park signal. When the park signal has been received by the vehicle ECU, the vehicle braking system is employed, thereby preventing the movement of the vehicle.Type: GrantFiled: August 11, 2003Date of Patent: July 31, 2007Assignee: Bendix Commercial Vehicle Systems, LLCInventors: Thomas J. Weed, Kenneth A. Grolle, Joseph M. Macnamara, Kirit A. Thakkar, Majed M. Hamdan

Patent number: 6862504Abstract: A system and method for detecting alternator condition is provided. Information is taken from the vehicle powerline and the communication links, and processed by the vehicle ECU, such as the vehicle antilocking brake system ECU, to obtain data. The battery voltage ripple amplitude is then calculated and compared at different engine speeds. If the difference in the ripple amplitude at the different engine speeds is greater than a predetermined threshold value, a signal is sent indicating that the alternator has failed.Type: GrantFiled: September 10, 2002Date of Patent: March 1, 2005Inventors: Marv M. Hamdan, Gusztav Holler, Kenneth A. Grolle, Joseph M. Macnamara, Kirit A. Thakkar

Patent number: 6456083Abstract: A method and apparatus for diagnosing short circuit conditions in a circuit protects circuit components from being damaged during a diagnostic operation. The apparatus includes a control processor, a control circuit coupled to the control processor, and an A/D converter coupled to the control processor and the control circuit. In operation the control processor disables operation of an A/D converter after completion of a conversion operation, enables operation of the control circuit after operation of the A/D converter has been disabled, enables operation of the A/D converter to obtain an analog signal from the control circuit after operation of the control circuit has been enabled, and disables operation of the control circuit after enabling operation of the A/D converter to obtain the analog signal. The A/D converter converts the analog signal into a digital signal and the control processor analyzes the digital signal to determine if a short circuit condition exits in the control circuit.Type: GrantFiled: March 3, 2000Date of Patent: September 24, 2002Assignee: Bendix Commercial Vehicle Systems LLCInventors: Kirit A.
