An interchangeable hearing aid control panel with at least one activation zone arranged in connection with a layered structure. The layered structure has an electrically non-conducting substrate, an electrically conducting path arranged in connection with the substrate, and an electrically conducting member, such as a conducting foil, arranged at a predetermined distance from the activation zone. The activation zone can be either in a deactuated or in an actuated state. In the actuated state the conducting member and the conducting path are electrically connected while disconnected in the deactuated state. Electrical connection to an associated hearing aid is by means of a connector, such as a plug, enabling the control panel to be easily changed. Preferably, the connector is formed by a piece of flexprint. The layered structure may comprise a second conducting path. In preferred embodiments activation zones are indicated by “poppel domes” formed by a surface layer covering the layered structure. The activation zones may form an MTO control or a volume control. To fit BTE hearing aids, the layered structure preferably has an elongated structure with a length of 1-4 cm. Other shapes can be formed to fit ITE, ITC and CIC hearing aids. In preferred embodiments, the control panel comprises one or more Silicon-based microphones protected behind a surface layer of the control panel.

A coaxial cable (10) includes at least one conducting wire (110), at least one insulating layer (120) coating a respective conducting wire (110), at least one shielding layer (130) surrounding the at least one insulating layer (120), and a single sheath (140) wrapping the at least one shielding layer (130). The shielding layer (130) includes a metal layer and a carbon nanotube film.

A module for a bus rooftop air conditioner is self contained in that it has all the necessary components including a compressor, if desired, which when supplied with electrical power, can provide conditioned air to the passenger compartment of a bus. In addition, an electrically powered heater is provided in the air flowstream such that heated air can also be supplied to the passenger compartment when desired. Multiple units provide for incremental capacity requirements to be met as well as limp home capabilities.

The present invention provides a recombinant vector pBI-3D-hGalT or pBI-35S-hGalT containing a human β1,4-galactosyltransferase gene; a cell line transformed with a recombinant vector pMYN414 containing a cytotoxic T-lymphocyte anti-gen A-immunoglobulin (CTLA4Ig) fusion protein gene and the recombinant vector pBI-3D-hGalT or pBI-355-hGalT; and a method for producing a plant-derived recombinant human CTLA4Ig (CTLA4Igp) fusion protein with a human glycan structure using the same. The plant cell-derived recombinant human CTLA4Ig fusion protein (CTLA4Igp), which has a human glycan structure and is produced according to the present invention, exhibits an improved in vivo half life as compared to conventional plant-derived proteins, due to the presence of a human-like glycan structure. Consequently, the present invention using the plant expression system enables low-cost mass production of a CTLA4Igp fusion protein having an immunosuppressive activity comparable to that of the CTLA4IgM fusion protein expressed in conventional animal cell expression systems.

Described herein is a passive wireless resonating non-linear sensor that is typically based on a ferroelectric varactor. The sensor replies its data at an intermodulation frequency when a reader device illuminates it at two closely-located frequencies. Furthermore, described herein is a general intermodulation read-out principle for passive wireless sensors. A sensor utilizes a mixing element, such as a varactor and it can be equipped with a capacitive, inductive, or resistive sensor element. When the sensor is illuminated with signals with two frequencies it replies the sensor data at an intermodulation frequency.

A luminescent vest equipped with plastic optical fibers having structural layers including a top layer of plastic film, a middle layer of plastic optical fibers and a bottom layer of a web-like structure. The middle woven layer has the following woven structure: (1) interwoven by lengthwise plastic optical fibers and crosswise plastic optical fibers; (2) interwoven by crosswise chemical fibers and lengthwise plastic optical fibers; (3) interwoven by lengthwise chemical fibers and crosswise plastic optical fibers. The three-layer structure is distributed at appropriate positions on the vest, while the top part of plastic film layer is arranged with letters or patterns serving to project light from the plastic optical fibers, and connected to electrical power to project alarm light effects. The present invention can be used in applications that include a traffic policeman's uniform, an environmental protection worker's uniform, a security guard's uniform and ordinary apparel.

The present invention provides improved optical switches in which only a spatial beam shifting of a small free space offset is required to direct optical pathways between plural fiber ports. This is achieved by spacing two fibers closely and collimating their beams with one imaging lens for compactness. Advantageously, the inventive switches incorporate beam correcting devices to render the beam propagations parallel, allowing light beams to be efficiently coupled into two fibers that sharing a single lens with substantially improved stability.

Fall detection method and systems with its unique designed sensors are disclosed. The capacitive sensing based systems use the abrupt changes of the capacitance value to detect whether a real fall event happens, while the reed sensor/or reed switch based systems work in power saving passive mode to detect the real fall event by analyzing the binary “on/off” signal available from the reed sensor/or reed switch. Both rely on the orientation change of the host body respects to local gravity direction during the falling process. The system can present either as a standalone system or a built-in component with supporting software installed on other devices.

The invention discloses a method for preparing nanometer ATO dispersing slurry fast, efficiently and cheaply. The method comprises the following steps: (1) successively adding silane coupling agent and ATO powder in water under stirring according to a weight ratio of to 0.005-0.02:1 to obtain ATO powder suspending liquid with the solid content of 16-55%, adjusting the pH value with alkaline solution to 9-11; (2) placing the ATO powder suspending liquid obtained by the step (1) in a ball mill to perform ball milling for 0.5-7.5 hours which adopts zirconium beads as ball-milling beads, removing the ball-milling beads to obtain slurry, fast adjusting the pH value with alkaline solution to 6-8; and (3) centrifuging the slurry obtained by the step (2) in a centrifugal machine under the rotate speed of 1000-4000rpm to obtain the nanometer ATO dispersing slurry. The preparation method of the invention is characterized by fast speed, electricity-saving and high efficiency; the average diameter of the particles of the prepared slurry is 25-50nm, the solid content is 15-50%, and the dispersing effect is very good.
