A method for making a biosludge-based biomass fuel includes: introducing an oxidizing agent gas and an aqueous solution into a biosludge to undergo lysis of bacteria contained in a biosludge under oscillation of the oxidizing agent gas and the aqueous solution so as to form a pre-treated biosludge mixture; filtering out the oxidized biosludge from the pre-treated biosludge mixture under pressurized treatment to form biosludge solids; drying the biosludge solids; grinding the dried biosludge solids to form particulate biosludge solids; and mixing the particulate biosludge solids with an oil sludge.

A dipole antenna assembly (100, 200) includes a dipole antenna (10, 30) and a feeding element (20, 40) connecting with the dipole antenna. The dipole antenna includes a radiation portion (12, 32), a ground portion (13, 33) and a circuit (14, 34). The feeding element includes a central conductor (21, 41) soldered on the radiation portion at a first position, and a shielding layer (23, 43) soldered on the ground portion at a second position. The circuit includes one end connecting with the radiation portion at the first position, and another end connecting with the ground position at the second position for impedance matching.

A mixed antenna system driving method for driving a mixed antenna consisting of a control IC, a sensor module and an antenna is disclosed. The control IC switches the antenna to a capacitive proximity sensor of the sensor module for enabling the capacitive proximity sensor to sense the approaching of an external object by means of the antenna, and then switches the antenna away from the capacitive proximity sensor to an electromagnetic wave generating circuit of the sensor module for enabling the electromagnetic wave generating circuit to perform an induction operation by means of the antenna after received a sensed signal from the capacitive proximity sensor, and switches the antenna back to the capacitive proximity sensor after the induction operation of the electromagnetic wave generating circuit.

A dual-band dipole antenna (100) includes a ground radiating portion (2), a signal radiating portion (3) and a feed wire (1). The feed wire (1) has a ground portion (12) connected to the ground radiating portion (2), and a core conduct (11) connected to the signal radiating portion (3). The signal radiating portion (3) has a first branch (31), a second branch (32) having a same length and a same width as the first branch (31), and a middle portion (33) connecting the first branch (31) and the second branch (32) at connecting points. Each of the first branch (31) and the second branch (32) has a first radiating length (D1) extending from the connecting point and a second radiating length (D2) extending from the connecting point.

A multiband antenna (10) includes a grounding element (11), a feeding element (12) resonating at a first frequency band, a first parasitic radiation (13) element spaced apart from the feeding element, and a parasitic element (14) disposed between the first parasitic radiation element and the feeding element for operating at the second frequency band. The first parasitic radiation element is designed for operating at a second frequency band.

The present invention provides an accurate machine monitoring technique based on vibration analysis. An AR parametric model is generated to characterize a normal machine condition. Subsequently, data is collected from a machine during operation. This data is fit to the AR parametric model, and an Exponentially Weighted Moving Average (EWMA) statistic is derived therefrom. The EWMA statistic is able to identify whether the machine is in a normal state ("in control") or in an abnormal state ("out of control"). Additionally, an EWMA control chart is generated that distinguishes between normal and abnormal conditions, and between different abnormal conditions. As a result, once the EWMA statistic is generated, it is compared to the EWMA chart for determination of the specific fault that is ailing the machine.

The invention provides a machine fault diagnostic system to help ensure effective equipment maintenance. The major technique used for fault diagnostics is a fault diagnostic network (FDN) which is based on a modified ARTMAP neural network architecture. A hypothesis and test procedure based on fuzzy logic and physical bearing models is disclosed to operate with the FDN for detecting faults that cannot be recognized by the FDN and for analyzing complex machine conditions. The procedure described herein is able to provide accurate fault diagnosis for both one and multiple-fault conditions. Furthermore, a transputer-based parallel processing technique is used in which the FDN is implemented on a network of four T800-25 transputers.
