Abstract: Systems and methods are described for off-site user access control to communications services via a site-based communications network. Embodiments operate in context of sites, each having one or more site-based networks in communication with external networks via one or more on-site routers. User devices are provided with controlled access to those external networks via wired or wireless connections between those user devices and the site based networks. In some embodiments, on-site routers maintain route maps that indicate which user devices are authorized. Standard routing functions are used so that traffic from authorized devices is routed normally, while traffic from unauthorized devices is automatically forwarded to an off-site (e.g., cloud-based) authentication system. As devices become remotely authenticated, the off-site authentication system can remotely update route maps of the on-site routers to add those devices.

A plurality of ultrasonic transducer elements and electrical pulser circuits are provided for generating and transmitting electrical pulses. The device has an interface configured to communicate with a single channel ultrasonic testing unit.

Abstract: An ultrasonic sensor assembly detects a characteristic of a pipe. The ultrasonic sensor assembly includes first and second transducer rings spaced apart along a length of the pipe. Each of the first and second transducer rings can transmit a first wave longitudinally along the pipe and receive a reflection of the transmitted first wave from the characteristic. The first transducer ring can use results related to the reflection of the transmitted first wave to guide a second wave along the pipe that is received by the second transducer ring. Methods of detecting a characteristic of the pipe are also provided.

Abstract: A coax server acts as a proxy between a coax transmission infrastructure and an Internet Protocol (IP) transmission infrastructure. An incoming request is received from a particular one of a plurality of coax client devices on the coax infrastructure. A request for specific media content is transmitted to a media-on-demand server in response to receiving the incoming request. A media stream is received over the IP infrastructure from the media-on-demand server, the media stream corresponding to the specific media content, and the coax server allocates a coax channel of sufficient bandwidth on the coax infrastructure and transmits the media stream on the coax channel utilizing the RF modulation scheme. A pointer indicating the coax channel on which the media stream is being transmitted is sent to the particular coax client device. The coax channel is unknown to other of the coax client devices besides the particular coax client device.

Abstract: Newly laid sod often requires extra support to stay in the correct spot to allow it to grow. The present invention relates to a device that allows for a more ergonomic and convenient way to securely drive sod or erosion control mat staples into the ground. The invention uses a handle connected to a driving rod. The driving rod is comprised of an elongated member that has a spring wrapped around it, with a spring restricting member on each end of the driving rod. These spring restricting members make sure the spring does not slip out of alignment when the spring is compressing or expanding. The driving rod is then securely attached to a driving plate. The driving plate and driving rod is what bears the force that is exerted on the handle and drives the pin into the ground. The entire structure is covered by a pair of protective members with a top end cap that prevents the users from getting their hand caught in the inner workings of the device, and an end cap that has an opening for inserting the pin.

One or more further pulses is selected that is related to the selected pair by having a respective reception time separated from the respective reception time of at least one pulse of the pair of pulses by one or more pulse repetition intervals from the set of pulse repetition intervals.

Abstract: Systems and methods are disclosed herein in which multi-level square wave excitation signals are used instead of or in addition to fully-analog excitation signals to drive an array of transceiver elements to create a sound field. Use of multi-level square wave excitation signals produces acceptable transceiver output with reduced complexity, cost, and/or power consumption as compared with use of fully-analog excitation signals. In addition, use of such signals facilitates system implementation using application-specific integrated circuits (ASICs) and is not as restricted in voltage level and speed. At the same time, the benefits and applications of fully-analog excitation signals (e.g., acoustic holography, beam superposition, signal-to-noise ratio (SNR) improvements, suppression of parasitic modes, increased material penetration, potential for coded pulsing algorithms and suppression of side lobes in ultrasonic field) can still be achieved with multi-level square wave excitation signals.
