A refractometer assembly comprises a waveguide plate, a diagnostic light source, a photodetector, and a light absorption plate. The diagnostic light source and the photodetector are optically coupled to the waveguide plate such that at least a portion of light emitted from the diagnostic light source is subject to internal reflection at a diagnostic surface of the waveguide plate prior to reaching the photodetector when an analyte film of unknown refractive index nforms an optical interface with the diagnostic surface of the waveguide plate. The light absorption plate is configured to absorb light reaching the light absorption plate without undergoing internal reflection at the diagnostic surface when the analyte film forms an optical interface with the diagnostic surface of the waveguide plate. The refractometer assembly defines an optical system where variations in the unknown refractive index nare related to variations in a detection signal generated by the photodetector.

An active device is supported on the first surface of the carrier, which is coupled to the body on opposite sides of the active device. The body and carrier are shaped so that a space is maintained between the active device and an underside surface of the body. The lens is positioned on the underside surface and aligned with the active device.

Systems and methods for attaching a cover to a text body to create bound documents with floating and attached spines are described. In some embodiments, a solid pressure sensitive adhesive film is applied between a cover and the side hinge areas of a text body, and a cover is bound to the side hinge areas of the text body with pressure. A solid pressure sensitive adhesive tape may be dispensed from an adhesive dispenser that includes a plug-in cartridge housing, a supply spool, and a take-up spool. In other embodiments, an adhesive sheet that includes a hot melt adhesive film and a backing is applied to the text body, with the hot melt adhesive film in contact with the side hinge areas and the spine of the text body. The hot melt adhesive is exposed in areas corresponding to the side hinge areas of the text body for attaching the cover to the text body. In one embodiment, an adhesive sheet includes a hot melt adhesive film and a backing layer that is attached to the hot melt adhesive film and has one or more slits extending in a substantially longitudinal direction. The slitted backing layer is configured to expose the hot melt adhesive upon stretching of the backing layer in a direction substantially orthogonal to the longitudinal direction.

A telecommunications device includes a portable telephone unit having both wireless communication capability and image capture capability, with a refocusing arrangement that is mechanically driven by operations of telephone components primarily included to enable telephone functions that are independent from camera functions. In one embodiment, the incoming call alerting device, such as the vibrator motor, is used to provide refocusing actuation. In another embodiment, the telephone unit is a 'flip phone' and the hinging operations store actuation force for refocusing operations. A ratchet cam may be used in the refocusing arrangement of the image capture capability.

Systems and methods for binding a text body are described. A multi-function sheet binder is configured to heat a preformed solid hot melt adhesive to a melting temperature, form the melted adhesive by pressing the melted adhesive into a spine of a text body and folding down edges of the melted adhesive into contact with the text body, and actively cool the formed adhesive. A spot heater is configured to heat one or more localized areas of a solid hot melt adhesive to a temperature sufficient to tack the hot melt adhesive to a text body spine. An adhesive former is configured to press a localized region of a preformed heated solid hot melt adhesive into a spine of a text body and to fold down edge regions of the preformed solid hot melt adhesive into contact with the text body.

The wafer-scale assembly method provides first elements arrayed on a wafer with adjacent ones of the first elements separated by a predetermined spacing. Second elements are also provided. A spacing-defining jig is provided that includes recesses corresponding in size to the second elements. Adjacent ones of the recesses are separated by a spacing equal to the predetermined spacing. The second elements are inserted into the recesses of the spacing-defining jig and are then affixed to the wafer with the second elements in alignment with corresponding ones of the first elements. Inserting the second elements in to the jig in which the recesses are separated by a spacing equal to the predetermined spacing allows a single alignment operation to provide accurate alignment between all the first elements, e.g., image sensors, arrayed on the wafer and all the second elements, e.g., lens assemblies, that are to be affixed to the first elements arrayed on the wafer.
