Abstract: A system for performing surface analysis on a material, includes a pulsed electron source that forms a monochromatic beam of incident electrons; means for conveying the incident electrons to the surface of a sample of material, so as to form backscattered electrons, and the backscattered electrons to detecting means, the conveying means comprising at least one electron optical system; means for detecting the backscattered electrons; the pulsed electron source comprising: a source of atoms; a continuous-wave laser beam configured to form a laser excitation zone able to excite the atoms to Rydberg states; a pulsed electric field on either side of the laser excitation zone, the pulsed electric field being configured to ionize at least the excited atoms and to form a monochromatic beam of electrons.

Abstract: An organizer, intended for use in holding cords or cables, has a main body and channels through which the cords or cables pass. The channels have a passage through which the user introduces or removes the cords or cables into or from the channels. One version has two end channels and two cable channels, the end channels having a cross-sectional space larger than the cable channels. The end channels can accommodate larger objects such as mobile devices, helping to hold such devices in convenient, viewable orientations. Another version has two end channels that are generally square or triangular in cross-sectional shape. Attachments, such as a mobile device stand, can be removably connected via crossbars sized to fit the cable channels or end channels.

Abstract: An organizer, intended for use in managing mobile device cables, has a main body that is optionally made of elastomeric material. The main body optionally contains a weight in a weight cavity. The main body is flexible. The main body has end channels and, in many versions, cable channels. The cable channels have a smaller cross section than the end channels. In some versions, the end channels or the cable channels have triangular cutaways that make it easier for the user to push cables or the like into the channels. In one version, the top and bottom surfaces at the end angle upward and downward with respect to the top and bottom main body surfaces. In some versions, the grips flare inward and form a notch to help retain things within the end channel while making it easy to remove when desired.

Abstract: A desktop organizer, intended for use in managing mobile device cables, in holding writing implements and earpieces, and in standing up mobile devices, has a main body that is optionally made of elastomeric material. The main body optionally contains a weight in a weight cavity. The main body is flexible. The main body has vertical end channels and cable channels. The cable channels have a smaller cross section than the end channels. In some versions, the end channels or the cable channels have features that make it easier to put items or cables in the channels. The main body may have a bottom channel that allows it to sit atop cords and keep them corralled.

Abstract: An organizer, intended for use in managing mobile device cables, has a main body made of elastomeric material and a weight contained in a weight cavity. The main body is flexible but comparatively less dense than the weight. The main body has end channels and, in many versions, cable channels. The cable channels have a smaller cross section than the end channels. In some versions, advantageously placing the cable channels helps make it easier to open up the end channels to accommodate a mobile device or various attachments.
