Abstract: When acquiring detailed utilization information from imaging equipment in a cross-vendor approach, one or more sensors (16, 18, 22, 24) are positioned within a data security zone (14) in which an imaging procedure is performed. Sensor data is pre-processed on an isolated processing unit (20) to remove any sensitive information and keep a selection of features only. The resultant feature pattern is transmitted outside of the data security zone to a processing unit (28) where pattern recognition is performed on feature pattern to identify the type of imaging modality, scan, etc. being performed as well as to determine whether the scan is being performed according to schedule.

Abstract: A high-temperature grease is disclosed comprising (A) 20 to 88 wt %, based on the total weight of the high-temperature grease, of a base oil, (B) 1 to 55 wt. %, based on the total weight of the high-temperature grease, of a fluorine-free material, the fluorine-free material having an average particle size (D50) of less than 80 ?m and being selected from the group consisting of (B1) a fluorine-free polymer which has aromatic, heteroaromatic, and/or heterocyclic groups and a melting or decomposition point above 200° C., fluorine-free phthalocyanin, and mixtures thereof; (B2) a melamine derivative, and/or 1,3,5-triazine-2,4,6 (1H,3H,5H)-trithione; and (B3) mixtures which contain a fluorine-free polymer and/or a fluorine-free phthalocyanin according to option B1 and a melamine derivative and/or 1,3,5-triazine-2,4,6 (1H,3H,5H)-trithione according to option B2, wherein the high-temperature grease does not contain polytetrafluorothylene and/or contains polytetrafluorothylene in a proportion of less than 6 wt.

Abstract: A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.
