Abstract:
The present invention relates to a method for monitoring and controlling a power system, characterised by the steps of: identifying a fault exceeding a predetermined threshold current in the power distribution system; verifying the identified fault to confirm the fault; generating a first digital signal upon fault confirmation; wherein the first digital signal activates protective operations against the fault, comprising the steps of: isolating a power supply to an electrical load (7); counting a number of fault occurrence and identifying a continuous fault occurrence; wherein the power supply to the electrical load (7) is restored if the number of fault occurrence is within a predetermined setting and no continuous fault occurrence is identified; wherein the power supply to the electrical load (7) remains isolated if the number of fault occurrence exceeds the predetermined setting or the continuous fault occurrence is identified; wherein the fault comprises lightning, earth fault, short circuit, power surges, transient, harmonic, and overcurrent; and wherein a second digital signal is generated by a fault diagnostic controller (10) to restore or isolate the power supply to the electrical load (7). An automatic power fault detection system is also disclosed in the present invention. Drawing accompanying abstract: Fig. 1
Abstract:
An electronic device having an enclosure formed from at least one glass cover and a peripheral structure formed adjacent the periphery of the glass cover is disclosed. The peripheral structure can be secured adjacent to the glass cover with an adhesive. The peripheral structure can be molded adjacent the glass cover so that a gapless interface is formed between the peripheral structure and the periphery of the glass cover. In one embodiment, the peripheral structure includes at least an inner peripheral structure and an outer peripheral structure.

Abstract:
A proposed wind, solar and rain harvester is described. The hybrid wind harvester (10) comprises a power-augmentation-guide-vane (12) and a wind turbine (14) sharing a centre axis as the guide vane. The novel power-augmentation-guide-vane (11) has an upper wall duct (22) and lower wall duct (24) inclined at an angle of 2 degrees to 75 degrees from the horizontal plane. The power-augmentation-guide- vane creates a venturi effect to increase the speed of wind entering the wind turbine to harvest more wind energy. A solar panel or solar concentrator is provided on top of the upper wall duct. A rain water passage and storage compartment is provided where rain water flows form the upper wall duct towards the rain water passage and storage compartment.
Abstract:
An apparatus and method for/of monitoring, regulating and controlling alternating current (AC) supply to electrical loads (7) in a building is disclosed. It includes a first system which detects the power faults in individual loads (7) and transmits a signal to a processing unit where the signals are processed. It optionally includes a second system means comprising of central intelligence unit to verify data, carry out diagnosis and pre-designated tasks. A signal from the first system means is sent to and received by the second system means which calls up one or more pre-designated recipients to report the power fault and provide full information about the fault and status of the load (7) and whereby the recipient can verify the power fault, status of the loads (7) and issue switching instructions to the first system means through the second system means.

Abstract:
The atmospheric water generation system of the present invention is capable of extracting water from the atmosphere using refrigeration-based compression cycle and heat exchange between ambient air and gaseous refrigerant supplied by an existing refrigerant source, and having a dual-purposed air pre-conditioning means for boosting water condensation efficiency at low temperatures, and said air pre-conditioning means having a second purpose of suppressing the undesired growth of molds and algae when the ambient humidity is relatively high. In addition, the atmospheric water generation system comprising an evaporator, air extractor, internal water storage tank, means of removing water stored in said internal tank to external appliances and storage units, temperature, humidity and water level measurement means, fluid dryers, capillary tubes and actuator valves makes it cost effective and well-suited for fixed and mobile applications in both indoor and outdoor environments.
