Abstract: A method and system employing deep learning techniques improves processing speed and spatial resolution of acoustic wavenumber spectroscopy (ASSESS) techniques by performing semantic segmentation on simulated ultrasonic wavefield images of a steady-state, select-tone excitation of a structural or mechanical component. One or more embodiments may employ a convolutional neural network (CNN), pre-trained on openly-available datasets, and trained by transfer learning on an augmented wavefield dataset, to localize and characterize defects or damage from inspection measurements of components.

Abstract: A cordless telephone outlet device that not only provides the cordless telephone access to a telephone network, but also provides the cordless telephone the proper DC electrical energy for proper operation eliminating the need for an unsightly external DC power supply typically connected to an AC outlet. Further, the device significantly reduces exposure of the telephone line connection between the cordless telephone and the telephone network. The outlet device comprises a body having a communications connector mounted thereon and a base attached to the body. The base contains DC power supply circuitry that is connected to a source of AC electrical energy. The output of the power supply circuit is connected to a DC line terminated with a DC male plug.

Abstract: Indicator means located in a plug or connector indicates when at least one phase of an AC multi-phase voltage is absent. The indicator means can be any one of a variety of light sources and/or an audible generator. The light source can be, for example, an LED, an illuminating ring visible from any angle around the body of the plug or connector, etc. An opaque barrier can be used to totally or partially block the light from the light source when light from the light indicator may be objectionable such as during a stage lighting application. The indicator means for detecting the absence of at least one phase can be on a printed circuit board connected to receive power from the conductors in the plug or connector.

Abstract: A method of adding a device to an existing or new electrical or electronic automation or multimedia network. The invention facilitates adding a device to the network that can communicate using various protocols such as LonWorks, CEBus, X-10, etc. over media such as AC power line, IR, RF, twisted pair, optical fiber, etc. The method is a mechanism for adding a device to a system that can be used by an ordinary user of network capable electrical devices. The method comprises the steps an installer would perform including the handshaking that needs to occur between devices to accomplish the binding process. A Functional Profile for LonWorks networks is given as an example. This includes a Home Device profile that employs an automated explicit type messaging for all devices intended for use in a home environment. The invention includes adding to the device an install button and a visual indicator for status such as an LED.

Abstract: A multifunction sensor device which provides various transducer functions including means for performing temperature sensing, humidity sensing, ambient light sensing, motion detection, thermostat functions, switching functions, load switching and dimming functions, displaying actual and set temperature values, displaying time of day values and a means to put the device in an on, off or auto mode. The device has utility in environments such as that found in offices, schools, homes, industrial plants or any other type of automated facility in which sensors are utilized for energy monitoring and control, end user convenience or artificial or natural cooling, heating and HVAC control. The device can be used as a switch or dimmer, sensor or thermostat as well as to adjust and control all natural and artificial lighting, temperature and humidity devices.
