Abstract: A touchless sensor includes a printed circuit assembly, a light guide and a sensor lens that are carried by a housing. The sensor lens is of hand shape. The housing corresponds in size and shape to a standard 19 mm push-button housing to allow for retrofitting to convert an electronic device from push-button operation to touchless operation.

Abstract: A disposable seal carriage for use with a liquid jet cutting system can include a body having a first end portion, a longitudinal axis, and a second end portion opposite the first end portion along the longitudinal axis. The first end portion can have a first outer width as measured perpendicular to the longitudinal axis, the second end portion can have a second outer width as measured perpendicular to the longitudinal axis, and the first outer width can be greater than the second outer width. The seal carriage can further include a flexible region extending through at least a portion of the body along a portion of the longitudinal axis. In some embodiments, the body includes a plurality of exterior projections positioned between the first and second end portions.

Abstract: A catalytically active composition for use in electroless plating, which is prepared without the use of acid by reacting an aqueous halide solution (chloride or bromide) of a palladium salt with a compatible tin salt. The tin salt can be molten or in the form of an aqueous solution containing water in an amount which is insufficient to cause precipitation of the tin. The final concentrated product may be used to prepare working bath solutions for electroless plating by dilution with an appropriate acid solution; but the concentrate itself contains essentially no free acid and may be either a liquid or a solid material, depending on process conditions.
