Patent number: 11852764Abstract: A seismic switch (SS) that is able to detect and signal when internal faults have occurred within the SS is described. The SS provides safety class functionality to the detection of seismic activity. For example, the SS may detect earthquakes above a specified level, resulting in the disconnection of electrical power to a radioactive waste storage facility, which could result in the ignition of waste materials should the storage facility and/or storage container fail during a seismic event. By reducing the risk of fire under these circumstances, the possibility of offsite releases is significantly reduced.Type: GrantFiled: July 26, 2019Date of Patent: December 26, 2023Assignee: TRIAD NATIONAL SECURITY, LLCInventor: Allen D.

Patent number: 9424733Abstract: The invention relates to a device for securing objects against unauthorized removal. To this aim, the device (26) comprises an alarm electronics unit (1) having a motion sensor (3), an environmental brightness sensor (4), and an alarm signal transmitter (5). The alarm electronics unit (1) is designed so that the ambient brightness sensor (4) is activated by the detection of a movement. However, alarm release occurs only if the ambient brightness measured at the ambient brightness sensor (4) exceeds a predetermined brightness threshold, and the movement last continuously for a predetermined time span. The alarm activation occurs only if the ambient brightness falls below a predetermined darkness threshold and the movement continues to persist.Type: GrantFiled: February 21, 2012Date of Patent: August 23, 2016Inventor: Rainer Brenner

Patent number: 8988238Abstract: Systems and methods are provided for monitoring operating machinery, acquiring data regarding characteristic behavior of the machinery being monitored, and processing of the data to determine and indicate when significant deviations from normal operating conditions are occurring that represent maintenance initiating or failure mode events. The method includes learning what normal operating conditions are for a machine of interest by acquiring data during observed normal operation, then calculating detection threshold values based on the acquired data. Finally, real-time monitoring of the machinery of interest during operation is employed, with alarms triggered upon occurrence of a previously-defined number of occurrences of behavior exceeding parameters associated with normal operation behavior.Type: GrantFiled: August 21, 2012Date of Patent: March 24, 2015Assignee: General Electric CompanyInventors: Charles Terrance Hatch, Steven Ross Hadley

Patent number: 8947237Abstract: The present invention utilizes an accelerometer (included within a wireless physiology monitoring device or as part of a separate device such as, but not limited to a smartphone, e.g., iPhone, or other mobile device) to link a patient with a separate medical data acquisition device such as a weight scale or a blood pressure monitor in order to collect and transmit a range of medical data associated with the user. The medical data acquisition device includes a vibration source for emitting a vibration at a predetermined or random frequency. When the acquisition device is activated, a vibration is transmitted from the through the patient and is detected by the accelerometer. The accelerometer then measures the particular frequency of vibration and transmits this information to a centralized monitoring unit (CMU). Based on the measured frequency, the CMU is able to know that the same patient wearing/holding the device is also the same patient using the data acquisition device.Type: GrantFiled: August 19, 2011Date of Patent: February 3, 2015Assignee: Xanthia Global LimitedInventors: Kenneth Margon, Gubbi Umesh Renukanand

Patent number: 8930046Abstract: A system for detecting degradation of a servo valve; having a controller, a servo valve, a position sensor, and a rate monitor. The controller receives inputs and transmits command data. The servo valve has an actuator and is conductively coupled to the controller to receive command data from the controller and move the actuator in response to the command data. The position sensor operably associated with the servo valve for measuring movement of the actuator and transmits corresponding movement data to the controller. The rate monitor coupled to the controller and position sensor for receiving the command data and the movement data as inputs respectively. The rate monitor processes the inputs to produce a steady state rate error signal. The rate monitor compares the steady state rate error signal to selected operational limits and produces a telemetry output when the operational limits are exceeded.Type: GrantFiled: November 16, 2011Date of Patent: January 6, 2015Assignee: Textron Innovations Inc.Inventor: Joseph M.
