Dielectric liquid is used to cool heat generating electronic components disposed on a circuit board within a case. The liquid is poured or otherwise directed over the electronic components, with gravity assisting the liquid in flowing downward over the components, with the liquid thereafter being collected in a sump for eventual return back to the electronic components. One exemplary application of the described concepts is in cooling electronic components in computers, for example personal computers or server computers.

A differential test probe for a printed wiring board test system includes a probe body having a proximal end and a distal end. Each of a plurality of coaxial cables extending from the proximal end to the distal end. The plurality of coaxial cables each includes a center conductor having an axial aperture at the distal end. The differential test probe also includes a plurality of signal pins that are each mounted in the axial aperture of the center conductor of one of the plurality of coaxial cables to electrically couple the signal pin to the center conductor. A plurality of ground pins are coupled to the probe body and selectively arranged relative to the plurality of signal pins to provide multiple signal to ground paths between the plurality signal pins and the plurality ground pins.

A magnetic levitation system for immobile patients in a wheelchair is disclosed. A magnet multi-pole configuration that is mechanically stable is provided that lifts the body and/or load shifts (rotates the body from side to side) the body. Based on a multi-pole configuration of permanent magnets in the pelvis, a corresponding multi-pole configuration for magnet repulsion is placed below the patient, typically as part of the wheelchair. Alternatively, a unipolar repulsion with mechanical patient restraint is implemented to achieve body lift or levitation. Either permanent magnets or electromagnets, optionally with magnetic sensor-mediated active computerized feedback control below the body, are sufficient to implement a complete multi-pole repulsive configuration that is mechanically stable. The apparatus reduces compressive force on soft tissues disposed between a human pelvis and a wheelchair seat.

An apparatus and system for inducing stimulation of muscles within the mouth. The apparatus includes a housing having a controller. A muscular contact member extends from the housing and is configured to contact muscles within the mouth, including for example the palate and the tongue. A vibrating device cooperates with the controller and muscular contact member to transmit vibration to the muscular contact member and in turn to muscles within the mouth. In the system, such an apparatus is provided that is rechargeable. A storage base receives the rechargeable apparatus when it is not in use and includes a battery charger. The storage base also optionally includes disinfecting means for cleaning the muscular contact member.
