Abstract: An apparatus includes a body assembly, an acoustic waveguide, an ultrasonic blade, a liquid dispensing feature, and a control module. The liquid dispensing feature is positioned distally relative to the body assembly. The liquid dispensing feature is positioned adjacent to the ultrasonic blade. The liquid dispensing feature is configured to deliver a flow of cooling liquid to the ultrasonic blade. The control module is operable to regulate fluid flow through the liquid dispensing feature.

Abstract: A headphone set can enable the substantially simultaneous output of two or more audio sources to a user. The audio from the multiple sources may be mixed so that a listener can hear and understand audio received from multiple audio sources. Thus, in certain embodiments, a user can consume media and also engage in conversation with other users or listen to ambient sounds, such as a telephone ringing or an alarm. Further, a mobile device, such as a mobile phone, can mix audio from multiple sources enabling a user to consume audio from the device while also listening to ambient sound or audio received from a source other than the device, using currently-available headphones.

Abstract: A lighter includes a heating element, a data store to store a smoking management plan including one or more rules, and a processor, operatively coupled to the data store and the heating element, to selectively disable activation of the heating element based on the smoking management plan.

Abstract: A well pump puller, which includes a base, a support element supporting a spindle, and an elastic element, extracts a well pump from within a well by winding electrical wiring attached to the pump around the spindle. During an extraction, at least a portion of any arising yank forces are absorbed by deformation of the elastic element, which reduces the risk of the wiring failing mechanically. A spindle can include a rotation element for rotating the spindle; a spindle lock and safety latch to limit rotation of the spindle; a wire guide to guide the wire; a pipe guide to guide a water pipe connected to the pump; a pipe catch to catch the pipe if the wiring fails; and a drill abutment that can abut a drill used to rotate the rotation element.

Abstract: A well pump extractor, which includes a base rotably supporting a spindle, a pipe guide, and a pipe catch, extracts a well pump from within a well by winding electrical wiring attached to the pump around the spindle. During an extraction, a pipe guide guides the path of water pipe connected to a pump. If the electrical wiring fails mechanically during an extraction, the pipe catch catches the water pipe, which prevents the pump from falling to the bottom of the well.

Abstract: A CMOS differential transmitter and matched receiver apparatus and method for transmitting data. The system uses a CMOS bias network to create low voltage swings and optimize the voltage offsets to compensate for variations caused by the manufacturing process, and thereby increase data transmission rates to approximately 1 gigabit per second.
