Abstract: Disclosed herein are advantageous measuring devices, and systems of the present disclosure and adjustment methods/techniques thereof. The present disclosure provides improved measuring devices (e.g., pressure/temperature measuring devices), and improved systems/methods for adjusting one or more features (e.g., offset and/or span) associated with measuring devices. More particularly, the present disclosure provides sealed measuring devices (e.g., sealed signal conditioning devices, such as sealed pressure transducers or transmitters) having adjustment members (e.g., magnet members) that allow a user to adjust the offset and/or span of the sealed measuring devices. The measuring devices include an adjustment member that allows a user to make adjustments to one or more features of the measuring devices. For example, a sealed pressure transducer can include an magnet member that allows a user to make fine (precision) adjustments of output offset and/or span (e.g.

Abstract: A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled in series electrical connection between an AC power source and an electrical load, and to be further coupled together via an accessory wiring. The remote devices can be wired on the line side and the load side of the load control system, such that the main device is wired “in the middle” of the load control system. The main device is operable to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half-cycle of the AC power source. The main device and the remote devices are operable to communicate with each other via the accessory wiring during a second time period of the half-cycle.

Abstract: A load control system comprises a main load control device and a remote load control device, which does not require a neutral connection and allows for feedback at the remote load control device. The main device and the remote load control device are adapted to be coupled between an AC power source and an electrical load. The main load control device comprises a load control circuit for controlling the amount of power delivered to the electrical load. The main load control device is operable to enable a charging path to allow the remote load control device to charge a power supply during a first time period of a half-cycle of the AC power source. The main load control device and the remote load control device are operable to communicate with each other during a second time period of the half-cycle.

Abstract: A cat-ear power supply is operable to generate a DC voltage and draws current from an AC power source near the beginning and end of a half-cycle of the AC power source. A controllably conductive switching circuit selectively charges an energy storage capacitor to produce the DC voltage and become conductive to charge the energy storage capacitor near the beginning of the half-cycle of the AC power source. A latch circuit controls the controllably conductive switching circuit to become non-conductive in response to the magnitude of the DC voltage. A switch voltage monitor circuit controls the controllably conductive switching circuit to become non-conductive and resets the latch circuit when the magnitude of a switch voltage across the switching circuit exceeds a predetermined switch voltage threshold. The switching circuit becomes conductive to charge the energy storage capacitor near the end of the half-cycle when the magnitude of the switch voltage drops below the predetermined switch voltage threshold.
