  • Patent number: 10957209
    Abstract: Methods and apparatus for preventing collisions between drones based on drone-to-drone acoustic communications are disclosed. A control system of a first drone includes a route manager to command the first drone to track a first route. The control system further includes a plurality of acoustic sensors arranged on the first drone to detect acoustic signals. The control system further includes a collision prevention engine to determine a second route based on acoustic signals detected by the acoustic sensors, the acoustic signals being received from a second drone while the first drone is tracking the first route. The second route differs from the first route to prevent a drone-to-drone collision between the first drone and the second drone. The collision prevention engine is to cause the route manager to command the first drone to track the second route instead of the first route.

  • Patent number: 10759533
    Abstract: Components of a device may transmit signals between one another using piezo electric transducers (PETs). In a basic system, a first PET may be coupled to and/or in contact with a first location on a member. A second PET may be coupled to and/or in contact with a second location on the member and separated from the first PET by a distance. The first PET may receive a signal (e.g., an electrical voltage) and convert the signal to a mechanical force/stress causing vibration of the member. The vibration may propagate through the member to other locations about the member. The second PET receive the vibration and may convert the vibration back to the signal, such as by converting mechanical force/stress to the electrical voltage (i.e., the signal). A similar process may be performed in reverse to enable the first and second PET to provide two-way communication.

  • Patent number: 8988238
    Abstract: 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.

  • Patent number: 8947237
    Abstract: 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.

  • Patent number: 8930046
    Abstract: 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.

  • Publication number: 20140320298
    Abstract: A detection system for identifying deterioration in a structure is provided that has acoustic sensors that receive acoustic emission waves. The acoustic emission wave detected by the acoustic sensor is identified as a hit. An analysis circuit is present that identifies an A state, a B state, and a C state. The B state has increased hit activity from the A state where a rate B is greater than a rate A by a factor of f1. The C state has increased hit activity from the B state where a rate C is greater than the rate A by a factor of f2. An alarm is activated when an amount of time that the C state is identified as being present reaches a value of TM, or alternatively when a threshold value based upon of the number of hits and time in the C state is reached.

    Abstract: A user provides relevant information about the operating parameters of a machine to be monitored to a diagnostic instrument. The user also specifies a location of the machine to be monitored, an alarm level to be set, and the type of alert to be sent. The instrument then automatically generates appropriate an alarm threshold using a set of rules applied to the inputs. The instrument then transmits the alarm threshold to a removable stand-alone monitor. The stand-alone monitor acquires data about the machine, compares the date to the alarm threshold, and sends a user-specified alert when the alarm threshold has been reached. Using the diagnostic instrument and monitor, machines can be monitored for vibration, temperature, or a power parameter.

  • Patent number: 8849587
    Abstract: A method for determining the health of a transformer through vibration measurement is disclosed. A vibratory signal, in the form of a physical mechanical vibration or auditory signal, is received at a sensor. The vibratory signal is converted into a frequency representation of the signal to derive its harmonics. Based on the power level for the harmonics in the vibratory signal, the harmonic current ratios in the transformer are calculated. The harmonic current ratios are summed together to quantify the health of the transformer. This value is called a K-factor, and is a quantification of the health of the transformer.
