A parcel safe system comprising a parcel safe in communication with a server, providing remote access and control of the system. The parcel safe system may be integrated into a home or building structure itself, significantly reducing the risk of package theft. The parcel safe system may use modular construction, allowing for customization, and may incorporate smart home technology. The parcel safe system may provide a controlled environment, suitable for temporary storage of groceries and prescriptions.

Parcel safe system

A method and system of high speed radio frequency communication between an outside of a metallic pipeline or vessel and an interior volume contained by the metallic pipeline or vessel includes passing a high speed radio frequency signal through a communication portal having a high speed radio frequency permittive material exposed to the interior volume of the metallic pipeline and to the outside. The high speed radio frequency signal may be transmitted from the interior volume to the outside or from the outside to the interior volume. The communication portal may be a cylindrical- or planar-shaped body connected to the metallic pipeline. A tool located within the interior volume may transmit, receive, or transmit and receive the high speed radio frequency signal. The high speed radio frequency signal may be configured according to a 2.45 GHz standard protocol.

Use of high speed radio frequency protocols for communication with pipeline pigs and inspection tools

A pipeline pig signal made according to this invention houses one or more shielded magnetometer sensors and a microcontroller with adaptive thresholding detection means for reducing the likelihood of false alarms. The adaptive thresholding detection means removes outlier data from the magnetic flux data stream and then passes the outlier-free data stream through four low pass filters. A smoothed magnitude of the data stream is compared to detection limits and, if a passage event has occurred, a recent detection is indicated, a counter of a display unit is incremented, a time of passage is recorded, and both statistics are displayed on the display unit. Because a single object may produce multiple magnetic fields, the detector may be locked-out for a predetermined period of time after the passage event to prevent a second detection of the same object as it passes the detection device.

The invention relates to a sensor electrode connected to a card module that can be received within an industry standard plug-in receptacle of a selected computer to enable a combination capable of very exhaustive data detection, processing, storage and the like for whatever the selected data sensor and particular card module.

A method and an apparatus are provided for measuring the wall thickness of a pipeline through which a fluid flows, the pipeline having an interior and exterior surface. The apparatus has a pig body supported by elastomeric cups to thereby cause the pig body to move by fluid flow through the pipeline. The pig body supports a plurality of multi-element transducers. Each transducer is made up of a large number of independent elongated rod-like crystal elements separated by a polymer, each having side walls, a front face and a bottom face. The rod-like elements are arranged so that the side walls are adjacent but mechanically isolated from each other, such as by an epoxy, with the front faces and bottom faces providing transducer front and bottom surfaces. A front metallic film and a bottom metallic film are applied to the front and the bottom surfaces. Each transducer is configured to have an impedance that closely matches the impedance of the pipeline fluid. Each transducer is activated by periodic electrical pulses to cause transmission of an acoustic signal in the pipeline fluid that are reflected by the pipeline interior and exterior walls. A plurality of multiple ultrasonic reflections from the pipe interior and exterior walls for each ultrasonic pulse produced by each transducer is analyzed employing a software algorithm embedded in the electronics within the pig body to provide a measurement of pipe wall thickness. By means of an odometer attached to the pig body, electrical signals are provided that reveal anomalies in the wall thickness of the pipeline relative to the distance traveled by the pig body so that an operator can thereby determine the location in the pipeline wall thickness anomalies.
