Patent number: 11724945Abstract: The present disclosure relates to systems and methods for monitoring the fill level of salt in a brine tank of a water softener system. Distance measurements may be taken by a wireless-enabled smart sensor device disposed at an interior surface of a brine tank cover. Calibration of the smart sensor device may include taking distance measurements corresponding to different fill levels of the brine tank, obtaining at least one corresponding user-defined fill ratio, and storing these as calibration data. Subsequent distance measurements may be used to determine a current fill ratio based on the calibration data. If the current fill ratio is below a threshold value, an alert may be sent to the user device indicating that salt should be added. If the current fill ratio is above a previous fill ratio, an alert may be sent to the user device requesting recalibration of the smart sensor device.Type: GrantFiled: February 12, 2020Date of Patent: August 15, 2023Assignee: PENTAIR RESIDENTIAL FILTRATION, LLCInventors: Ramakrishna Budampati, John Stauch

Patent number: 10018487Abstract: The present disclosure provides methods and systems for initiating sealed sensor units in the field. A packaged sensor unit may include a sensor module, an activation mechanism and an internal battery, all situated in a sealed enclosure. In some cases, the sealed enclosure may be devoid of any externally accessible switches. A pre-defined triggering stimulus may be applied to the packaged sensor unit, and the pre-defined triggering stimulus may be detected via the activation mechanism. In response to the activation mechanism detecting the pre-defined triggering stimulus, the internal battery may be connected to the sensor module. Prior to detecting the pre-defined triggering stimulus, both the sensor module and the activation mechanism may draw no power from the internal battery of the packaged sensor unit. In some cases, the activation mechanism, once activated, irreversibly couples the power supply to the sensor module.Type: GrantFiled: June 15, 2011Date of Patent: July 10, 2018Assignee: Honeywell International Inc.Inventors: Ramakrishna Budampati, Jeff Becker

Publication number: 20070091825Abstract: Wireless communication systems using transmitter initiated communications methods. Several devices in the system listen by following a common frequency hopping sequence. When communication is desired, a transmitting device sends a request to send signal to an addressee; if available, the addressee sends a clear to send signal, and the transmitting device and the addressee then perform communications using a separate frequency hopping sequence. Methods for adding new devices are also included. In an example, a new device uses a discovery frequency hopping sequence to ping a number of frequencies until the common frequency hopping sequence is discovered. In another example, a new device listens on a single frequency forming part of the common frequency hopping sequence until the common frequency hopping sequence overlaps the single frequency.Type: ApplicationFiled: October 21, 2005Publication date: April 26, 2007Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Ramakrishna Budampati, Patrick Gonia, Soumitri Kolavennu

Publication number: 20060227729Abstract: A system of wireless infrastructure nodes are communicatively coupled to a number of internally powered leaf nodes. The leaf nodes may have sensors and/or actuators. A wireless leaf node transmits data to an infrastructure node at a time according to a duty cycle. When a collision occurs, the data is retransmitted until an acknowledgement is received from an infrastructure node. A change in a transmission protocol parameter, such as duty cycle/phase of sampling is initiated with such retransmissions. A decision to change the parameter is taken either by the wireless leaf node itself, or by an infrastructure node. Some of the leaf nodes can be transmit-only devices which repeat each data packet a number of times.Type: ApplicationFiled: April 12, 2005Publication date: October 12, 2006Inventors: Ramakrishna Budampati, Patrick Gonia
