This disclosure relates to an indicator cap for a pipe penetration. In one aspect, the indicator cap comprises a cap body, wherein the cap body comprises an engagement portion for engaging the indicator cap with the pipe, and a capping portion connected to the engagement portion for covering an open end of the pipe, and wherein a surface of the capping portion supports a means for aiding location of the indicator cap and thus the pipe, wherein the means for aiding location is adapted so as to not impede screeding thereover, and to indicate the position of the cap and thus the pipe post screeding.

A ground penetrating radar stencil and system for using the same is provided. The stencils are reusable. The stencils are foldable, allowing for storing and transportation. A first data collection grid stencil is used to mark a grid followed by alternative target marking stencils used to mark utility line and structural support lines. Indelible stencil paint/ink is applied on and through the stencils onto the concrete surfaces to provide for a permanent, standardized and consistent marking of critical embedded infrastructure. The system allows for a uniform collecting and recording of the scanning data results for future reference and work in the same area.

The clean-out cap locator forms a cap that encloses a clean-out plug. The clean-out cap locator comprises a threaded cap, a control circuit, a remote control, and a personal data device. The control circuit determines the GPS coordinates of the control circuit. The control circuit transmits the GPS coordinates of the control circuit to the personal data device. The control circuit generates an audible alarm indicating the location of the clean-out cap locator. The control circuit senses the flow of fluid around near the clean-out cap locator. The control circuit transmits an alarm to the personal data device when the control circuit senses a back-up in the clean-out plug. The control circuit generates an audible alarm when the control circuit detects a back-up in the clean-out plug. The remote control sends a signal to the control circuit that causes the control circuit to generate an audible alarm.

A medical supplies cabinet is disclosed. The cabinet comprises a housing presenting a medical supplies storage zone at where there is provided at least one medical supplies receptacle. The receptacle(s) is/are of a shape and configuration to be able to at least partly receive and hold at least one medical item. A sensor is associated with the receptacle(s). The sensor is configured to generate a signal indicative of the presence and/or absence, or removal of the medical item in/from the receptacle.

Provided is a passive wireless magnetic field characteristic sensing tag and system, and a magnetic field quantity acquisition method, which integrates a passive magnetic field quantity sensor in a passive electronic tag and cooperates with a reader and a host computer to build a magnetic field sensing system, so as to realize high-precision and high-intelligence monitoring of the magnetic field quantity.

There is provided a mmWave RTLS (Real-Time Location Sensing) system for detecting the presence of one or more objects. The system includes multiple anchors. Each anchor includes a mmWave radar subsystem that uses radar algorithms to detect one or more objects and determine the one or more location-based objects characteristics. The location-based object characteristics include one or more of the following: range, direction-of-arrival, velocity, absolute position, or logical position, each determined relative to one or more anchors.
