Abstract: A noise control system is operable within a box-like structure provided by the dual bulkhead plenum of the vehicle dashboard positioned within the transfer path along which the noise is being transmitted from the source of the generated noise to the receiver of the noise in the passenger compartment of an automobile. The plenum is divided into discrete chambers into each of which is provided a counter noise generating apparatus to create a counteracting noise offsetting the noise generated at the source. The acoustic resonance of the chambers amplifies the noise control energy. The geometry of the individual chambers can be varied to optimize the packaging and sound control or shaping strategy. The sound energy permitted to pass through the plenum to the driver's side of the passenger compartment can be tuned to be different than the noise received in the passenger's side.

Abstract: A door monitor with a portable storage medium includes a host module disposed behind the door, a night-vision camera module disposed outside the door and electrically connected with the host module, a sensor disposed outside the door for detecting whether any object is approaching, and a microphone connected with the host module. The host module has a multimedia processor, a display, a touch panel, and a portable storage medium connecting interface. The user enters monitoring criteria using the touch panel. When an object approaches and stays for a period of time, the night-vision camera module starts recording. The recorded video data are sent to and played on the display. The video data are compressed in a format and stored on the portable storage medium. The door monitor readily monitors situations outside the door and records and stores video images for the purposes of home security.

Abstract: A noise control system is directed to the path along which the noise is transmitted from the source of the noise being generated to the receiver of the noise in the passenger compartment of an automotive vehicle. The noise control system is deployed in a box structure, such as the dual bulkhead of the dashboard of the vehicle, to provide a constrained volume within which engine noise can be controlled. The dual bulkhead plenum houses an active noise control apparatus, such as a speaker or a vibrating device, between the bulkheads to be operable with a control algorithm to generate sound that can control the noise or vibrations generated by the engine. The plenum can also be treated with passive noise control materials, such as viscoelastic damping materials, acoustical foam or heavy vinyl barrier and foam to block airborne sound and vibrations, in addition to the active noise control.

Abstract: A noise control system operable within a box-like structure provided by the dual bulkhead plenum of the vehicle dashboard positioned within the transfer path along which the noise is being transmitted from the source of the generated noise to the receiver of the noise in the passenger compartment of an automobile. The plenum is divided into discrete chambers into each of which is provided smart materials affixed to the walls of the plenum to be operable for selectively changing a property characteristic of the chambers to vary the acoustic resonance of the plenum and change the effectiveness of controlling the transmission of noise energy therethrough. A controller is coupled to the smart materials to change said property characteristic of the smart material in response to noise cancellation requirements.

Abstract: An adaptive noise control system is deployed in a box-like structure positioned within the transfer path along which the noise is being transmitted from the source of the generated noise to the receiver of the noise in the passenger compartment of an automobile. The adaptive noise control system is can be deployed in the dual bulkhead of the vehicle dashboard to provide a constrained volume within which engine noise can be controlled. The adaptive control system generates a mathematical model of the noise to be controlled in response to the acoustic environment identified by sensors placed within the engine compartment. Sensors in the passenger compartment define the effectiveness of the noise control system. The controller is operable to update the mathematical model in response to the changes in the acoustic environment, thus providing the appropriate acoustic response within the dual bulkhead plenum for control of noise along the transfer path.

Abstract: A document positioning apparatus has a supporter. The supporter is disposed under a base of a document camera. A gap is formed between the supporter and a ground surface used to support the supporter and the gap is designed to be large enough for a document to shift. The document positioning apparatus further has a document guider, formed on an edge of the supporter to guide the document into the gap under the supporter easily.

Abstract: An image sensing element encapsulating method includes the steps of mounting an image sensing element having thereon terminals on a substrate having thereon connecting terminals by surface mounting technique, combining the terminals on the image sensing element and the connecting terminals on the substrate, mounting a glass plate on the substrate to be opposite to the image sensing element, forming joints on the substrate and outside the image sensing element and forming a solder ball or a solder bump on each of the joints.

Abstract: A method for cleaning semiconductor elements includes steps of positioning the semiconductor elements; washing the semiconductor elements by high-pressure water steam or solvent steam from front, top and rear sides to blow out soldering flux or oil residue; and repeating washing by steam two or three times. As the steam molecules are small, the semiconductor elements can be cleaned thoroughly by the steam. The temperature of the steam is relatively low, so the semiconductor elements will not be damaged.

Abstract: A transmission mechanism that can be applied in a document camera is disclosed. The transmission mechanism includes a first roller, a second roller, a first lever and second lever. The first roller and the second roller rotate about individual axes. Ends of the first lever are pivoted about the axis of the first roller and the axis of the second roller, respectively; and ends of the second lever are pivoted about a shift point of the first roller and a shift point of the second roller, respectively. The first lever and the second lever are uncrossed.

Abstract: An image sensor package and method of assembling the same utilizes an overlay pattern containing multiple lens mounts and a glass plate to laid over a substrate. The substrate has multiple chip pads formed at predetermined locations for holding sensor ICs. Each lens mount is positioned on the periphery of the chip pad and completely sealed off by a glass plate The stacked layers are then cut vertically to form individual blocks, completely detached to form image sensor packages.

The torsional modes are discerned by use of the torque generator 14 such as an internal combustion engine, which is normally and operatively disposed within the vehicle 12, thereby obviating the need to replace the internal combustion engine 14 with a dynamometer and/or other type of signal generator assembly.
