A method of making alkali-metal vapor cells by first forming microscale-wax micropackets with alkali metals inside allows fabrication of vapor cells at low cost and in a batch fabricated manner. Alkali metals are enclosed in a chemically inert wax to preform alkali metal-wax micropackets, keeping the alkali metals from reacting with the ambient surroundings during the vapor cell fabrication. This enables the deposition of precise amounts of pure alkali metal inside the vapor cells. Laser ablation of the alkali metal-wax micropackets provides a simple and effective way of releasing the enclosed metal. The method reduces the cost of making chip-scale atomic clocks and allows shipping of alkali vapor packets without contamination issues, thereby creating a technology for alkali-metal vendors to provide small packets of alkali metals.

An ultrasonic probe that is pressed to a subject to obtain an elasticity image. The probe has a contact surface used for contact with the subject and is orthogonal to the direction of the pressing and has an automatic pressing means or a manual pressing means. The automatic pressing means is adapted for moving the contact surface in a pressing direction to press a to-be-imaged portion of the subject at a predetermined pressing force, and manual pressing means presses the portion by a manual force. Using the ultrasonic prove having the automatic pressing means or the manual pressing means enables a pressing stage to be automatically or manually moved in a vertical fixed direction at a desired speed, and as a result elasticity image data with high image quality can be obtained at a desired time. Further, repeatability of pressing operation can be retained, which enables a problem of the quality of an elasticity image being dependent on an inspector to be eliminated.

A redundant LED backlight and method for controlling the same. At least two plurality of LEDs are used to create a backlight where any individual set of LEDs may be driven at power level P to provide the desired overall luminance for the backlight. If two plurality of LEDs are used, then the LEDs may be driven simultaneously at one-half P during normal operations until a failure has been detected in one of the plurality of LEDs. In alternate embodiments, four plurality of LEDs may be used and driven simultaneously at one-fourth P during normal operations until a failure has been detected in one of the plurality of LEDs. The LEDs may be in edge-lit, direct-lit, or any combination of these two orientations. Upon failures, only one plurality of LEDs may be used to provide operation of the LED backlight and any associated LCD device.

A measuring method and measuring apparatus for vector-measuring a scattering coefficient of a device under test substantially using a scalar measuring instrument while enabling a reduction in the size of the measuring instrument and the cost. The measurement system includes a signal source that applies a signal to a device under test, a scalar measuring instrument that measures a reflected wave reflected from the device under test or a transmitted wave transmitted through the device under test as a scalar value, and a superimposing signal system that superimposes three different vector signals whose relation values are specified in advance on the reflected wave or the transmitted wave of the device under test. The three vector signals are superimposed on the reflected wave or the transmitted wave of the device under test, and the superimposed signals are each measured as a scalar value by the electric-power measuring instrument. The three measured scalar values are converted into a single vector value using the specified relation values of the three vector signals, thereby obtaining a transmission coefficient of the device under test.
