Abstract: An electromagnetic interference suppression circuit and a related sensing circuit. The sensing circuit includes an input and an output operatively coupled with the input. The input is adapted to be connected on a power line and in series between a load and a shunt circuit connected across power lines between a power source and the load. The output is adapted to provide a signal (Vs) associated with an electromagnetic interference signal (Vn) generated by or at the load and arranged to be experienced by the shunt circuit. The signal (Vs) can be used for determining a suppression signal (Vn?) for reducing, or substantially eliminating, the electromagnetic interference signal (Vn). The electromagnetic interference suppression circuit includes the sensing circuit, a regulator circuit, and a controlled signal source.

Abstract: A circuit for suppressing electromagnetic interference signal on power lines. The circuit includes a first sensing circuit, a first amplifier, and a first controlled signal source. The first sensing circuit is arranged to sense a first electromagnetic interference signal. The first amplifier is arranged to be powered by a power source. The first amplifier provides a first amplification factor and being operably connected with the first sensing circuit to amplify a signal sensed by the first sensing circuit. The first controlled signal source provides a second amplification factor and is operably connected with the first amplifier to regulate or further amplify the amplified signal to provide a first suppression signal that reduces the first electromagnetic interference signal. Multiple such circuits can be cascaded to form a mufti-stage electromagnetic interference suppression circuit.

Abstract: A light fixture includes a central housing, a panel, a light source, and a tether. The central housing defines first and second side surfaces and a bottom surface, and the bottom surface defines a plane. The panel is pivotably coupled with the first side surface, and the light source is coupled with the panel. The tether is coupled at one end with the panel to pivotably suspend the panel, and the second end of the tether includes an attachment member. The attachment member is configured to selectively couple with any one of a plurality of anchor positions located on the central housing. The panel is therefore fixable between a plurality of angles relative to the plane as determined by the attachment member being coupled with a selected one of the plurality of anchor positions.

Abstract: A method for securing transaction in a blockchain network and a related system with a blockchain network. The blockchain network has information handling devices operably connected with each other. The information handling devices collectively maintain a blockchain ledger containing one or more transaction blocks with transaction information. The method includes validating a new transaction request to be added to the blockchain ledger. The validation includes digitally signing, at two or more of the information handling devices in the blockchain network, respectively, an interim block associated with the new transaction request, using a HASH value of the interim block and respective private keys of the two or more of the information handling devices. The method also includes verifying the one or more signed interim blocks for determining whether to add to the blockchain ledger a new transaction block containing the validated new transaction request and the at least two digital signatures.

Abstract: A system and method for operating a blockchain network including ledger servers arranged in a first mesh network and collectively maintaining a blockchain ledger. The method includes: determining that a new transaction data block is to be added to the blockchain ledger, and assigning a mining task: (i) to one or more and not all of the ledger servers; or (ii), via one or more of the ledger servers, to one or more electrical IoT devices operably connected with the respective one or more ledger servers. The mining task is to compute a HASH value associated with the new transaction for adding the new transaction data block to the blockchain ledger.

Abstract: A handheld electronic device has an outer face in which a user display and a navigation touch pad are located. The touch pad is adapted to provide a user input for controlling at least one function of the electronic device. A plurality of touch sensors are located at predetermined locations about the area of the touch pad and detect touching by a user's finger in order to provide an output control signal. A light source is associated with each touch sensor. A control unit receives input from the touch sensors and activates each light source in turn as the associated touch sensor is touched by a user, so that the user receives visual feedback as they are controlling the device.
