摘要:
A sound wave generator is effective for producing ultrasonic sound wave vibrations as well as low frequency vibrations which are offensive to rodents. A wiring conductor which serves as a sonic radiator is attached to an end portion of a solenoid rod which is reciprocated by a coil which is energized by alternating current power. The solenoid rod is permitted to vibrate within a hollow spool, and the sonic radiator is mechanically coupled to the solenoid rod by a high compliance, conductive metal spring. Ultrasonic sound waves are produced by forming the solenoid rod of a ferromagnetic material which is characterized by magnetostriction in the presence of an alternating magnetic field. The amplitude of sound wave vibration is intensified by selecting the length and diameter of the solenoid rod so that its natural frequency of vibration is in harmony with either the pulse frequency of the electromagnetic driving force, or alternatively, the frequency of ultrasonic sounds produced by magnetostriction. The sound wave generator circuit includes a pseudo-random signal generator for randomly gating the conduction of electrical alternating current through the solenoid coils during a pulsing duty cycle.

A bottle is disclosed that includes a product stored therein. It is configured to be removably engaged with a docking station in an inverted arrangement to be activated by the docking station and heat the product. The bottle may include a pump structure (e.g. in the form of a bellows), or be a squeezable bottle, or be a bowable bottle, or have other pumping features. Structures are provided to prevent drool after use, to help apply the heated product to the skin, and to insure proper heating and dispensing. Also disclosed are combined docking stations and bottles where the bottle is positioned in an inverted manner, and methods for using these devices.
摘要:
A method and system for converting the output of a communications port (e.g., a serial port or a USB port) into video signals representing the output of a terminal. The system is interposed between the communications port and a set of two or more inputs to a keyboard, video and mouse switch. Upon receiving characters from the communications port, the system interprets the characters as terminal emulation commands and internally generates a representation of what a resulting terminal screen would look like. From that internal (digital) representation, the system produces analog outputs representing the terminal screen. The analog outputs are applied to the video input of the KVM switch such that the terminal output can be viewed on the monitor attached to the KVM switch.

A drive train support tool is provided for supporting drive train components in a motor vehicle. The tool includes a tubular body having opposite ends, with extension members telescopically extending from the opposite ends of the body. A hook is provided on each extension member for hooking over the torsion bars or other suspension system components or opposite sides of the vehicle frame. A jack extends through the tubular body and can be threadably extended into a supportive engagement with the drive train component(s). Therefore, the tool will support the engine or any other drive train component while another drive train part is removed for work or repair at a location away from the vehicle.

A method of and system for cleaning a surface applies a first fluid to the surface by feeding the first fluid from a unitary cleaning receptacle removably secured to a cleaning unit and moves the unitary cleaning receptacle relative to the cleaning unit to agitate the cleaning solution. A second fluid is applied from the unitary cleaning receptacle to the surface and at least a portion of the first fluid and at least a portion of the second fluid are captured in a recovery compartment of the unitary cleaning receptacle
