Publication number: 20250100599Abstract: A system for enhancing personnel safety on a railroad track is presented. The system can receive data from sensors and/or a PTC system to determine positions of clients/worker and/or vehicles, and further utilize such data to determine if a vehicle is within a certain proximity of the client/worker location. The system can further generate geofences around clients/vehicles to and determine when such geofences intersect one another. Additionally, the present disclosure can assign severity levels and generate alerts with the assigned severity levels, and such severity levels can indicate how close a vehicle is to a particular location. It is an object of the invention to provide a system for generating alerts to notify personnel when they much retreat to a place of safety.Type: ApplicationFiled: February 8, 2024Publication date: March 27, 2025Applicant: BNSF Railway CompanyInventors: Eric Peter Olsen, Shanmugasundram Rajasubramanian, Nithin Paul Mathew, Marutha Pandian Jagadesan, Michael Howard, David Himmelstein, Aamir Ahmad Halim, Wayne Morgan, Amit Kumar Dash, Jacob Bunkley, Dickson Waudo, William Stewart, Raven Wylie

Patent number: 12179555Abstract: A method for defogging a window of a vehicle includes steps of automatically selecting a climate control system operating mode and determining a risk of window fogging. The climate control system operating mode is selected from an outside air mode, an air-conditioning mode, and a defrost mode. A controller determines the risk of window fogging according to one or more inputs, and the same or a different controller may automatically select the climate control system operating mode. The controller is configured to increase a climate control system blower speed to increase a rate of airflow provided by the currently-actuated climate control system operating mode. The controller may sequentially advance the climate control system operating mode through the outside air mode, air-conditioning mode, and defrost mode.Type: GrantFiled: October 23, 2023Date of Patent: December 31, 2024Assignee: Ford Global Technologies, LLCInventors: Alan Gutowski, Manfred Koberstein, William Stewart Johnston

Publication number: 20230316028Abstract: Surgical articles, such as sponges, are provided in a pack which contains individual surgical articles having UHF RFID or other electronic labels which provide both (a) unique identification information for each article as well as (b) unique identification information for all articles in the pack. Prior to the surgical procedure, the labels are scanned and the identification information for all articles in the pack uploaded to a processor to create a list of available individual surgical articles. At the end of the surgical procedure, the surgical articles are collected and the electronic labels read and compared to the initial list to determine if there are any unaccounted individual surgical articles. The UHF RFID tag may then be used to determine a location of the unaccounted article outside the patient’s body.Type: ApplicationFiled: October 12, 2022Publication date: October 5, 2023Applicant: Innovo Surgical, Inc.Inventors: Brian E.

Patent number: 11660935Abstract: A vehicle thermal management system including an electric powertrain, a single thermal loop, and a controller is provided. The electric powertrain includes a high voltage battery. The single thermal loop is for managing thermal conditions of the high voltage battery and a vehicle cabin and may include a climate control system, a blower, and a front evaporator in fluid communication with the vehicle cabin. The controller is programmed to, responsive to detection of a climate control system off request, output a command to direct the blower to push air through a heater core to the vehicle cabin at a predetermined temperature such that a temperature within the vehicle cabin is maintained at a predetermined temperature and refrigerant continues to flow through the front evaporator. The system may include a vehicle cabin temperature sensor and an ambient temperature sensor, each in electrical communication with the controller.Type: GrantFiled: September 16, 2020Date of Patent: May 30, 2023Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Alan Gutowski, Curtis Mark Jones, William Stewart Johnston, Manfred Koberstein

Publication number: 20230118833Abstract: A thermal accessory controller for controlling the temperature of a thermal accessory. The thermal accessory controller comprises a liquid reservoir for storing a thermal liquid that circulates through the thermal accessory, a temperature control system (TCS) in liquid communication with the liquid reservoir that adjusts the temperature of the thermal liquid according to a TCS target temperature value, and a control unit that controls the temperature control system using the TCS target temperature value. The control unit receives a TCS target temperature, receives a temperature measurement from a temperature sensor, and determines a magnitude of a difference between the TCS target temperature and the temperature measurement. The control unit executes a proportional-integral-differential (PID) algorithm to cause the temperature control system to adjust the temperature of the thermal liquid based on the difference between the TCS target temperature and the temperature measurement.Type: ApplicationFiled: September 27, 2022Publication date: April 20, 2023Applicant: CardioQuip, LLCInventors: William Stewart, John Dean
