Abstract: Methods, apparatuses, devices, and optical components are described. One or more materials used in an optical system may be bonded together using a pulsed laser beam. The bonding process may include transmitting a pulsed laser to irradiate an interface between two components, which may include two optical components or an optical component and a mounting component. The pulsed laser may generate one or more bonding locations where the components are in relatively close contact with each other, which may secure the components together via at least partial melting of material at one or more surfaces of the components. In some examples, the pulsed laser may be scanned over the bonding locations some quantity of times and/or using a pattern to achieve the bond. In some aspects, one or more absorbing layers may be added to the components.

Abstract: A display device (30) comprises a reflective display (38) arranged to render a first image viewable through a viewing surface and a projection means (31-37) arranged to render a second image viewable in reflection on the viewing surface, the reflective display (38) and the projection means (31-37) being mounted on a common frame.

Abstract: A removable cap for receiving a writing implement includes a reverse clip. The cap has a hollow crown section for receiving the writing implement and an elongate cap extension that extends axially from the hollow crown section and includes an end that terminates in a clip flange. An elongate holding prong projecting substantially perpendicular from the clip flange and extending and opening toward the closed first end of the crown section in substantially parallel-spaced relation to the cap extension so as to define in conjunction with the cap extension and the hollow crown section, an elongate U-shaped slot, which is adapted to snugly engage an attachment material inserted into the slot. A gripping member is located within the U-shaped slot and is configured to intimately engage the attachment material inserted into the slot to assist in maintaining the engagement between the cap and attachment material when the writing implement is removed from the cap.

Abstract: A process for simultaneously producing PET-usable quantities of [.sup.13 N]NH.sub.3 and [.sup.18 F]F.sup.- for radiotracer synthesis is disclosed. The process includes producing [.sup.13 N]NO.sub.2.sup.- /NO.sub.3.sup.- and [.sup.18 F]F.sup.- simultaneously by exposing a low-enriched (20%-30%) [.sup.18 O]H.sub.2 O target to proton irradiation, sequentially isolating the [.sup.13 N]NO.sub.2.sup.- /NO.sub.3.sup.- and [.sup.18 F]F.sup.- from the [.sup.18 O]H.sub.2 O target, and reducing the [.sup.13 N]NO.sub.2.sup.- /NO.sub.3.sup.- to [.sup.13 N]NH.sub.3. The [.sup.13 N]NH.sub.3 and [.sup.18 F]F.sup.- products are then conveyed to a laboratory for radiotracer applications. The process employs an anion exchange resin for isolation of the isotopes from the [.sup.18 O]H.sub.2 O, and sequential elution of [.sup.13 N]NO.sub.2.sup.- /NO.sub.3.sup.- and [ .sup.18 F]F.sup.- fractions. Also the apparatus is disclosed for simultaneously producing PET-usable quantities of [.sup.13 N]NH.sub.3 and [.sup.18 F]F.sup.
