摘要： A common zero volt reference AC/DC power supply with positive and negative rectification, and method of operation thereof. The power supply comprises an input for receiving an AC input voltage and an output for outputting a DC output voltage, the AC input and DC output having a common zero volt reference. The power supply comprises a first rectifier and a second rectifier, for respectively performing a half-wave rectification of a positive half cycle and negative half cycle of the AC input voltage. The power supply comprises control logic for detecting the negative half cycle of the AC input voltage and activating the second rectifier upon the detection. The power supply comprises a power converter for converting a DC rectified voltage received from at least one of the first and second rectifiers into the DC output voltage.

摘要： The present disclosure relates to an environment control device (ECD) and a method using a wireless communication infrastructure for exchanging environmental data. The wireless communication infrastructure comprises a first Wi-Fi hotspot, and at least one of a second Wi-Fi hotspot and a mesh network. The ECD comprises a communication module for exchanging environmental data with at least another device over the wireless communication infrastructure. The communication module is capable of establishing the first Wi-Fi hotspot, associating with the second Wi-Fi hotspot, and communicating over the mesh network. The ECD further comprises a processing module capable of processing environmental data received from the other device via the wireless communication infrastructure, and/or transmitting generated environmental data to the other device via the wireless communication infrastructure. The ECD may consist of an environment controller, a sensor, a controlled appliance, and a relay for wired devices.

摘要： The present relates to a system and a bidirectional differential pressure sensor. The system and bidirectional differential pressure sensor comprise a first adaptor comprising an end configured to receive a first pipe, and a second adaptor comprising an end configured to receive a second pipe. The system and bidirectional differential pressure sensor further comprise a pressure sensing element determining a pressure differential between fluid received via the first adaptor with respect to fluid received via the second adaptor. The system or bidirectional differential pressure sensor further comprise a processing unit executing an algorithm for generating an adjusted pressure differential based on the pressure differential determined by the pressure sensing element.

摘要： A system comprising a housing, a printed circuit board and a differential pressure sensor located inside the housing, and first and second male adaptors. The first and second male adaptors respectively extend through first and second openings in the housing. The first male adaptor comprises a proximal end configured to receive a first pipe, a distal end secured to the differential pressure sensor, and an internal fluid conduit for transmitting fluid received from the first pipe to the differential pressure sensor. The second male adaptor comprises a proximal end configured to receive a second pipe, a distal end secured to the differential pressure sensor, and an internal fluid conduit for transmitting fluid received from the second pipe to the differential pressure sensor. The differential pressure sensor is configured to determine a pressure differential between fluid received via the first male connector and fluid received via the second male connector.
