Abstract: A mouthpiece for a single reed musical instrument, such as a clarinet, is made with a tubular body having an outer surface and having a facing angle. The mouthpiece is made so that its facing angle is 4 degrees or less to enable musicians to play music with much fuller and more pleasant sounds then in the prior art.

Abstract: A method for a communication between two cellular phones is provided, in which the communication between the cellular phones includes an intercom communication and a telephone communication. The method includes steps of providing a telephone number of one cellular phone and an intercom number associated with the telephone number in the other cellular phone, dialing the telephone number of the one cellular phone by the other cellular phone to activate a calling to the intercom number associated with the telephone number, determining whether the cellular phones are within an intercom communication area, and performing the intercom communication therebetween while the cellular phones are within an intercom communication area, or performing the telephone communication therebetween while the cellular phones are without an intercom communication area.

Abstract: Methods and apparatus for determining leak and respiratory airflow are disclosed. A pressure sensor (34) and a differential pressure sensor (32) have connection with a pneumotach (24) to derive instantaneous mask pressure and airflow respectively. A microcontroller (38) estimates a non-linear conductance of any leak path occurring at a mask (12) as being the low pass filtered instantaneous airflow divided by the low pass filtered square root of the instantaneous pressure. The instantaneous leak flow is then the conductance multiplied by the square root of the instantaneous pressure, and the respiratory airflow is calculated as being the instantaneous airflow minus the instantaneous leak flow. The time constants for the low pass filtering performed by the microcontroller (38) can be dynamically adjusted dependent upon sudden changes in the instantaneous leak flow.

Abstract: Disclosed herein is a printed circuit board having an RF module power stage circuit embedded therein. Specifically, this invention relates to a printed circuit board having an RF module power stage circuit embedded therein, in which a terminal pad for a resistor, a bead, or an inductor is defined or formed on a power supply plane of a multilayered wired board to connect the resistor, the bead, or the inductor to the power supply plane, and the resistor, the bead, or the inductor is connected in parallel with a decoupling capacitor by using a via hole or by embedding the resistor, the bead or the inductor perpendicular to the power supply plane, thus decreasing the size of the RF module and improving the performance thereof.

The invention also provides an improved optical reading system with the parameters satisfying the relationship: nd = ? 2 ? n ? m 1 + M T 2 , wherein ? is the wavelength of light used to read the information recording medium, m is the order of interference selected from a group consisting of odd integers, MT is the transverse magnification, n is the refractive index encountered by the reading light inside the pits, and d is the depth of the pits.

Abstract: An improved exercise apparatus for martial arts is provided and includes a longitudinally extending platform, a support on which the platform rests or is otherwise supported and a plate unit slidably carried along the platform and movable between a first retracted position and a second extended position in response to a force being applied to the plate unit by the leg or arm of an individual during exercise.

Abstract: In a dip soldering process, solder is pumped through a nozzle outlet. Leads of a component on a circuit board are dipped into the surface of the flowing solder to solder the leads to a track on the underside of the circuit board. To prevent solder bridging between the leads, a plate is provided below the solder surface, and passes between the leads. When withdrawing the leads from the solder, the solder surface is dropped to the level of the plate, so that excess solder is drawn away from the leads, preventing solder bridging between the leads. Member may be movable to rise through the solder surface as the circuit board is raised away from the surface.

Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor (16) receives an airflow signal from a pressure transducer (18) coupled to a port (17) at a mask (11). The microprocessor (16) controls a servo (19), that in turn controls the fan motor (20) and thus the pressure of air delivered by the blower (10). The blower (10) is coupled to a subject's mask (ii) by a conduit (12). The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.

Abstract: A mechanism that is comprised of two or more four-bar linkages is shown. Each linkage shares a common link with each adjacent linkage and the movement of said two or more linkages is synchronized by mechanical means such that said mechanism may move between a collapsed and an extended state. Said mechanical means may be in the form of additional links or geared connections.
