摘要:
A tuning system is described for automatically tuning a musical instrument having adjustment means for changing the frequency of a musical tone produced by a musical string of the musical instrument. The tuning system of the present invention is useful with respect to a wide variety of musical instruments, e.g., string instruments such as, guitars, harps, pianos, etc., and other instruments. A tuning system is operative to selectively tune a musical string of a stringed musical instrument to a user selected predetermined frequency value.
摘要:
Apparatus for compensating for positioning, pointing and/or orientation errors caused by deflections of structural members and components of a high performance machine or device and/or for reducing vibration inputs to such machine or device and/or for micro-positioning such machine or device so as to improve the operational performance of such machine or device. The apparatus utilizes one or more active-type actuators, such as piezoelectric ceramic type actuators, which are arranged in a predetermined manner relative to the machine or device. A servo control device operating in accordance with a predetermined algorithm may be utilized for controlling the actuators or, alternatively, the apparatus may operate in an open loop manner.

摘要:
A method for at least slowing a vehicle moving along a surface is provided. The method including; providing one or more panels capable of extending above the surface; and deploying the one or more panels from the surface into a position extended from the surface.
摘要:
The invention provides a treatment for congestive heart failure (CHF) in a patient. At least one pressure applicator is arranged externally around a body segment of the patient. Negative pressure, relative to atmospheric pressure, is applied to the body segment of the patient during cardiac systole using the pressure applicator, thereby reducing ventricular afterload in the patient. The negative pressure to the body segment of the patient is removed during cardiac diastole.

A method for automated treatment of an area of skin of a patient with laser energy. The method including: identifying the area to be treated with the laser; modeling the identified area of the skin to be treated; and controlling the laser to direct laser energy to within the modeled area of the skin.
摘要:
A method and system for treating a patient having an acute myocardial infarction. Such system may comprise at least one tank having a pressurized gas contained therein, at least one housing having a shell and being adapted to at least partially surround a body segment of the patient, a hose/valve device for supplying the compressed gas from the tank to the housing; and a control device for controlling the flow of compressed gas from the tank to the housing in accordance with cardiac systole and cardiac diastolic of the patient to vary the pressure in synchronization with the patient's heart function. The system may be arranged within a moving vehicle, such as an ambulance, an airplane, or a ship.
