Abstract: A device to hang articles includes a base defining a generally flat body to engage a mounting surface and a hook protruding therefrom to hang an article. The device also includes a bracket pivotally attached to the base at a proximal end of the bracket and a piercing arm extending from a distal end of the bracket. Also, the bracket is adapted to pivot between a first position relative to the base where the piercing arm is retracted from the mounting surface, and a second position relative to the base where the piercing arm is inserted into the mounting surface to retain the device thereto.

Abstract: A flow meter is powered by a loop power supply which supplies a supply voltage. A load is powered by a load voltage and includes at least a processor for calculating a flow rate, an ultrasonic transducer power circuit, and an ultrasonic transducer receiving circuit. A power regulating circuit is disposed between the loop power supply and the load. The power regulating circuit includes a power converter responsive to the supply voltage to vary the load voltage in response to a control signal, a safe storage device between the converter and the load for storing power when not needed by the load and for delivering power to the load when required by the load, and a control subsystem for providing the control signal to the converter based on the setting of the loop power supply by the load. A power management subsystem is configured to detect the load voltage and to reduce the power consumption of the load at one or more predetermined set points.
