Abstract: The present application relates to a smell sensing system (100) comprising a smell delivery device (104) for delivering an olfactory output (110). The smell delivery device (104) comprises a delivery channel (3) for receiving a substance (5a) from a canister (5), the substance (5a) configured to produce an olfactory output (114). The smell delivery device (104) also comprises an output component (7) through which the substance (5a) is emitted. The smell delivery device (104) also comprises one or more airflow generating elements (13) configured to generate airflow to transport the substance (5a) from the canister (5) to the output component (7). The smell sensing system (100) also comprises a smell sensing device (102) for detecting the olfactory output (110) delivered by the smell delivery device (104).

Abstract: A spectrometer includes an emitter that is configured to emit electromagnetic radiation, a sample area that is arranged at an outer face of the spectrometer, a modulation unit including an electrochromic material, an optical filter, an optical detector, an integrated circuit that has a main plane of extension, and an optical path for electromagnetic radiation emitted by the emitter towards the optical detector via the sample area, the modulation unit and the optical filter, wherein the electrochromic material is electrically connected with the integrated circuit, and the modulation unit is configured to modulate electromagnetic radiation temporally. Furthermore, a method for detecting electromagnetic radiation is provided.

Abstract: A dual-pawl ratchet wrench mechanism is disclosed having a stop mechanism for limiting over-travel of a reversing lever for selecting drive directions. In one form, the wrench mechanism includes a ball and spring assembly that cooperate with recesses to define proper positions for the reversing lever, and one or more ramps are provided between the recesses to promote tactile feel and to promote the reversing lever being rotated to a proper position. In some forms, the stop mechanism is formed on a stationary portion, such as a spacer or the wrench body, and a portion of the reversing lever. The design simplifies manufacturing, such as by simplifying assembly and minimizing the need for securements. Additionally, the reversing lever is assembled with the mechanism in a manner to improve sealing.
