Abstract: An apparatus for optical sensing of samples includes an optical source, an optical assembly being rotatable about an axis, a sample holder, and a detector. The optical assembly rotates, allowing the sensing apparatus to sense results from plural locations on a sample without moving the sample. Moving the sample in a linear direction while rotating the optical assembly allows sensing of an entire sample containing multiple test sites, such as a biochip. An optical assembly containing mirrors to direct light from the optical source to the sample is provided. Preferably, light enters the optical assembly along the axis of rotation. Sensing methods consistent with the invention are also described.

Abstract: An apparatus for optical sensing of samples includes an optical source, an optical assembly, a sample holder, an objective lens, and a detector. The objective lens collimates light emitted by the sample. Preferably, the optical assembly rotates about an axis, allowing the sensing apparatus to sense results from plural locations on a sample without moving the sample. Moving the sample in a linear direction while rotating the optical assembly allows sensing of an entire sample. Preferably, light from the optical source enters the optical assembly along the axis of rotation. Sensing methods consistent with the invention are also described.

Abstract: A handheld vertical scanning calculator apparatus is provided. It allows the user to add paper-borne columns of numbers quickly using just one instrument. The main components are a) a scanning input that scans numbers vertically b) an OCR equipped CPU that recognizes the scanned input c) a calculating unit and finally d) a display. Compared to existing means, the invention is a distinct progress since it a) reduces of time consumption and risk of input errors related with the use of traditional calculators, b) reduces the complications currently related to the combined use of a separate scanner with an external computer or PDA i.e. use of two devices and/or need to scan each individual number in the column separately. Technically the invention is a novelty due to its vertical scanning and since it performs scanning and adding in one instrument.
