Abstract: A bicycle assembly can have a main frame, a subframe, and a shock absorber. The subframe can move in relation to the main frame, and the shock absorber can be used to regulate that relationship. A linkage can be connected to the shock absorber, the main frame, and a chain stay of the subframe to drive the shock absorber as the subframe is moved with respect to the main frame.

Abstract: An otoscope including a head, a holder for an ear funnel, a primary lighting unit and a secondary lighting unit. The primary lighting unit is configured for examining the ear and the secondary lighting unit is configured for examining a part of the body that differs from the ear.

Abstract: An attachment assembly for a camera arm of a video laryngoscope including a spatula and a protective cap, wherein the spatula has a base body with a handle end and a patient end opposite the handle end as well as a channel formed in the base body for receiving the camera arm, wherein the channel is open both towards the handle end and towards the patient end, wherein the protective cap is a component part separate from the spatula, is insertable into the channel and includes an at least partially transparent protective section, wherein the protective cap is designed such that a tip of the camera arm of the video laryngoscope can be engaged in the protective section and to be covered by the protective section. Moreover, a video laryngoscope system is shown.

Abstract: An oxygen supply system providing an adequate oxygen supply mode in an aircraft. A preventive oxygen supply system includes an oxygen source, a preventive oxygen dispensing unit connectable to the oxygen source, a cabin altitude detection device, and a preventive oxygen control device provide at least the following modes: a pre-wear mode providing no oxygen of the oxygen source to the preventive oxygen dispensing unit but normal cabin air; a pre-oxygenation mode providing a predetermined rate of oxygen of the oxygen source to the preventive oxygen dispensing unit sufficient for generating a pre-oxygenation condition of the user; and a decompression mode providing high concentrated oxygen of the oxygen source to the preventive oxygen dispensing unit sufficient for ensuring a minimum oxygenation of the user. The preventive oxygen control device automatically switches to the decompression mode in case a predetermined cabin altitude threshold is detected by the cabin altitude detection device.

Abstract: A device for supplying breathing gas to a user includes: a mask having a breathing opening; and a bag having a bag opening that is connected to the breathing opening in fluid communication, wherein the device further includes an adjustable exhalation valve, wherein the adjustable exhalation valve is in fluid communication with the bag. Thus, the device for supplying breathing gas to a user provides protection against hyperventilation, toxic gases and smoke.
