Abstract: A dispensing apparatus, which is capable of delivering precise quantities of a liquid product less than one mm3 in size, includes a drive mechanism, a housing made up of at least two input channels coupled to a chamber made up of a first portion and a second portion. First and second component liquids are delivered via the first and second input channels respectively to the chamber and the first and second input channels are disposed so that interaction is hindered between the first component liquid and the second component liquid in either input channel. At least one feed screw with a helical thread is disposed in the chamber such that when the at least one feed screw is rotated by the drive mechanism the first and second component liquids are mixed to form a liquid product and the feed screw rotation also discharges the liquid product from the chamber.

Abstract: An input device, which is capable of changing the appearance of a display, includes a body made up of a cover and a base, a cable receiver, and a cable coupled to the cable receiver. The input device has a first mode with a first portion of the cable having a first length external to the input device and a second portion of the cable wrapped around the cable receiver. The input device also has a second mode with the first portion of the cable having a second length external to the input device less than the first length.

Abstract: A plug includes a disabling mechanism that, upon activation, resists removal of the shaft when inserted into a socket. The plug can also include an indicator that provides an indication that the disabling mechanism has been activated. The plug, which once inserted, changes the state of an electronic device in a substantially permanent manner.

Abstract: A portable electronic device, such as a portable notebook computer, that includes a case made up of a top portion and a bottom portion with a base surface. The case contains a speaker having a front portion and a back portion, where the back chamber is formed in association with the back portion of the speaker. A first aperture is disposed through the bottom portion of the case, and an acoustic insulator is attached to the base surface of the case such that the acoustic insulator encircles the first aperture forming an external chamber. The external chamber is defined by the base surface, and the acoustic insulator being adapted to rest upon a support surface upon which the portable electronic device rests. The external chamber is coupled to the back chamber by the first aperture.

Abstract: An electronic device that is sealed under vacuum includes a substrate, a transistor formed on the substrate, and a dielectric layer covering at least a portion of the transistor. The electronic device further includes a layer of non-evaporable getter material disposed on a portion of the dielectric layer; and a vacuum device disposed on a portion of the substrate. Electrical power pulses activate the non-evaporable getter material.
