Abstract: A method and system for determining mobile phone strain is provided. The method includes the steps of determining if strain on a mobile phone housing and/or strain on a printed circuit board (PCB) within the mobile phone exceed a predetermined value. If the strain(s) values exceed the predetermined value an alarm may be sounded and the strain values may be stored in memory for later retrieval and/or analysis.

Abstract: An improved, battery-operated liquid-crystal display (LCD) device designed to use the battery as a structural support for the LCD. The device, typically a cellular phone, media phone, or other telecommunications mobile station, includes a housing that encloses station components. The housing forms a window through which the LCD screen may be viewed when the device is in operation. A recess behind the LCD is formed for receiving a battery. The battery is made of a material that is sufficiently resistant to bending that, when the device, including the battery, is assembled, the battery structurally engages the LCD. That is, the battery provides at least some structural support to the LCD so as to reduce or eliminate deformation of the LCD that would otherwise have occurred due to a stress applied to the device.

Abstract: An apparatus for producing high intensity radiation has electrodes positioned within an elongated cylindrical arc chamber across which an arc discharge can be established. Liquid is injected into the arc chamber to produce a vortex motion therein to form a cylindrical liquid wall adjacent to the chamber, which constricts the arc by cooling an outer periphery thereof. Gas is injected into the arc chamber to produce a vortex motion adjacent the cylindrical liquid wall. An exhaust structure actively exhausts the liquid and gas from the arc chamber to reduce turbulence and restriction of fluid. This permits attainment of higher flux densities in the arc, and/or extension of electrode life. Preferably, the liquid and gas are exhausted actively by means of an ejector pump which ejects pressurized liquid into the gas and liquid leaving the arc chamber.
