Abstract: A noise management system for a window includes an active noise control (ANC) module and a passive sound absorbing module. The ANC module is disposed in or adjacent a ventilation channel of the window and configured to substantially cancel low-frequency noise entering the ventilation channel. The passive sound absorbing module is disposed in or adjacent to the ventilation channel and configured to absorb both high-frequency noise entering the channel and harmonic sounds generated by the ANC module.

Abstract: Wireless piezoelectric accelerometers and systems are provided. A wireless piezoelectric accelerometer may comprise a piezoelectric sensing element configured to sense mechanical acceleration and produce an electrical charge signal in response of the sensed mechanical acceleration, a signal processing module (SPM) configured to convert the electrical charge signal into a voltage signal, and process and digitize the voltage signal, and a wireless module configured to modulate and transmit the digitized voltage signal as wireless signals. The piezoelectric sensing element, the SPM and the wireless module are packaged in a casing. The casing comprises a metallic shielding chamber configured to enclose the piezoelectric sensing element. The casing further comprises a non-metallic portion located in relative to the wireless module to allow transmission of the wireless signals. Corresponding wireless piezoelectric accelerometer systems are also provided.

Abstract: A multi-directional wiring routing device and method for operating thereof removably or permanently connects to a female housing of an electrical connector system. The multi-directional wiring routing device secures thereon and directs the wiring, at any desired routing direction, the wiring extending from the female housing. The wiring routing device includes an end portion having a substantially diamond-shape configuration portion, which is fitted into a corresponding substantially diamond-shape opening of the female housing of the electrical connector system. While maintaining the optimal performance of the electrical connector system, a bundle of wiring thereof can be neatly secured and efficiently routed towards any desired direction with the use of the multi-directional wiring routing device.

Abstract: An influenza detector for detecting a targeted influenza virus and a surface acoustic wave (SAW) sensor for Influenza A virus detection in liquid are provided. The influenza detector includes a liquid environment, the surface acoustic wave (SAW) sensor and an influenza specific binding agent such as an antibody. The agent is immobilized on a surface of the SAW sensor for selectively capturing an analyte for the targeted influenza virus. The SAW sensor is in contact with the liquid environment and includes a substrate comprising a piezo-electric material for producing a surface acoustic wave signal in response to an applied electric field and an insulative layer formed on top of the substrate and having a functionalized surface formed thereon for selectively immobilizing the influenza specific binding agent, the functionalized surface being in contact with the liquid environment.

Abstract: An electrical connector having a squib connector and a squib assembly for mating by moving them together in a mating direction. A retaining means is provided for retaining the squib connector and squib assembly in a fully mated condition. A spring, acting in a direction opposite the mating direction, provides a resisting force to oppose mating. During the application of a mating force to overcome the resisting force of the spring and move the squib connector and squib assembly in the mating direction, and prior to the squib connector and squib assembly reaching the fully mated condition, removal of the resisting force of the spring is triggered and the mating force is instantly applied to moving the squib connector and squib assembly to the fully mated condition, whereat the retaining means is activated. The spring is molded to have features that assure dependable operation of the connector.

Abstract: A process, for patterning a thin film that is highly resistant to conventional etching processes and that is to be deposited at a high substrate temperature, is disclosed. The process uses a liftoff method wherein a refractory material has been substituted for the conventional organic resin. The method is particularly useful for the fabrication of tunable microwave devices and ferroelectric memory elements.
