Abstract: An earphone 1, which adopts the drum air power system the invention, includes at least a drum 5 composed of a drum-shaped casing 2, a front head 3 located on the front part of the casing 2, a rear head 4 located on the rear part of the casing 2, an inner-drum space 5a defined by the casing 2, the front head 3, and the rear head 4. Earphone 1 also comprises a driver unit 6 installed inside the drum 5 and equipped with an external sound conducting part 6a and an internal sound conducting hole 6b. The front head 3 and the rear head 4 resonate in response to driving by the driver unit 6 so that the low pitch sounds B and C are output in addition to the full range sound formed from the external sound conducting part 6a. This structure lowers the minimum resonance frequency and increases the sound pressure.

Abstract: A data packet generator periodically generates a data packet including a passcode comprising a plurality of characters. The data packet is sent to a server or a computing device for validation. If validated, the data packet is used, for example, to identify the location of a user or device. Additional systems and methods involving such a data packet generator are also disclosed.

Abstract: A novel electrical floor-hinge device is provided, which contains an electrical motor and a speed reducing element configured on top of a platform element at a side on top of a body member. A vertical input shaft connected to the speed reducing element is joined to a lateral involute shaft via bevel gears. The involute shaft in turn engages a driven gear on a vertical output shaft. The top end of the output shaft is attached to a seat element whose top surface is fixedly joined to a lower inner corner of a door. By the electrical motor's driving the seat element into clockwise or counterclockwise swing, the door is closed or opened automatically. The speed reducing element can be easily replaced to fit doors of different weight.

Its color index as measured by the absorbance of a 1% solution at 500 nm lies in the range 0.4 to 0.7. In addition, its combined content of fructose plus glucose is greater than 5%, preferably lying in the range 7% to 9% by weight relative to the dry matter.

Abstract: A fence includes an upright post and one or more rails radiating from the post. An arrangement for connecting the post to the rail or rails includes a carrier that can be mounted on the post and one or more holders for the rail or rails. Each holder is attached to the carrier by a hinge that allows the respective holder to pivot or rotate relative to the carrier in two different planes. An accessory bracket for flexible rails and a gate hinge may also be connected to the carrier.

Abstract: Embodiments of an electrostatic loudspeaker utilize first and second stators and a diaphragm disposed therebetween, each of the stators and the diaphragm having an electrically conductive portion, wherein the conductive portions of the first stators are electrically coupled to each other; the conductive portions of the second stators are electrically coupled to each other; and the conductive portions of the diaphragms are electrically isolated from each other. The first stators and the second stators may be realized by common first and second stators may be mounted obliquely with respect to one another, so as to achieve differentially greater spacing between stators of the first one of the speaker elements than between stators of the second one of the speaker elements. Protective circuitry is also provided.

Abstract: A mobile cremation urn includes a container portion having a volume in which cremation ashes are stored and a mounting portion coupled to the container portion to secure the mobile cremation urn to a moving vehicle. The container portion may be elongated and the mounting portion may be oriented substantially parallel with the container portion or a longitudinal axis thereof. The mounting portion may include a mounting flange, mounting posts, or mounting apertures. A removable closing member may be attached to the container portion and may seal the ashes contained therein. The closing member may also include a locking feature. The container may be fabricated with a corrosion resistant coating. A distinguishing mark may be displayed on an exterior surface of the container.

Abstract: The invention relates to a vehicle test stand including a device for fixing a motor vehicle on the test stand. A loading machine is adapted to be coupled to the drive train of the motor vehicle, whereby the loading machine can both drive and brake the drive train. In accordance with the invention, the loading machine is directly or indirectly connectable to a rim of a motor vehicle wheel in force-locking manner.

Abstract: An electrostatic speaker system is provided wherein a multitude of speakers are provided in the system, each speaker having a thin electrically conductive film membrane sandwiched between a pair of stator plates. The film membrane is directly coupled to a high voltage AC audio signal emanating from a power amplifier for reproducing an audio signal. The high voltage AC audio signal is not applied to the stator plates but instead indirectly coupled to the pair of stators by a plurality of condensers (in a voltage multiplier circuit) of a electrical circuit contained within each speaker of the system. By applying the high voltage AC audio signal to the film membrane, approximately one-quarter of the voltage typically used to drive an electrostatic speaker is required.

Abstract: A method of gradual deformation of representations or realizations, generated by sequential simulation, not limited to a Gaussian stochastic model of a physical quantity z in a meshed heterogeneous medium, in order to adjust the model to a set of data relative to the structure or the state of the medium which are collected by previous measurements and observations. The method comprises applying a stochastic model gradual deformation algorithm to a Gaussian vector with N mutually independent variables which is connected to a uniform vector with N mutually independent uniform variables by a Gaussian distribution function so as to define realizations of the uniform vector, and using these realizations to generate representations of the physical quantity z that are adjusted to the data.

Abstract: The present invention relates to a process for the solvent extraction of active compounds from chicory. Characteristically, according to the invention, chicory is macerated in said solvent at a low temperature, preferably of between 0° C. and 6° C., for a period of at least twelve hours; and the maceration liquor is filtered with a cut-off threshold of at least 0.22 &mgr;m. The present invention further relates to the use of the extract obtained by the process of the invention for the preparation of an oral hygiene composition and for the preparation of cosmetic products.

Abstract: An non-hybrid electrostatic speaker system is provided. Each electrostatic speaker contains a diaphragm positioned between pair of electrically charged stators. A central unit is provided having a plurality of slots for receiving a plurality of printed circuit boards. Each speaker employed within the system has a printed circuit board assigned thereto and is mounted within the central unit slots. A single DC power source within the central unit supplies a constant DC voltage to each electrostatic speaker. All electronics needed to operate the speakers are “de-coupled” from the speaker and located within the central unit. The central unit couples to an audio amplification device which is coupled to an audio sound producer.
