The second pivot plate may have a nub at the first hinge configured to accommodate a finger of a user. The accessory may have an undeployed configuration and a deployed configuration in which the sliding plate is translated along the frame such that the first pivot plate and the second pivot plate flex outwardly from the frame. In the deployed configuration, a portion of the first pivot plate may sit within a portion of the second pivot plate at the first hinge.

Accessory for electronic device

A method and apparatus for imaging within a sample space an object containing quadrupolar nuclei comprises irradiating the object to excite nuclear quadrupole resonance, applying to the object a magnetic field gradient having a profile Bo(x) such that the square of the profile (Bo(x))2 varies linearly with distance (x), detecting resonance response signals from the nuclei, and deriving an image from the response signals. A method of and apparatus for nuclear quadrupole resonance testing an object, and a method of and apparatus for detecting the presence of a particular substance containing a given species of quadrupolar nucleus, are also disclosed.
