Abstract: An apparatus for supporting a user includes a faceplate, an arm, a bridge, and a base. The bridge is rotatably attached to the faceplate to allow the faceplate to be pivotably adjusted. The bridge includes a hub with first and second hub bodies. Locking pins on the hub bodies slidingly engage pivot adjustment holes in first and second pivot adjustment rings. First and second buttons can be depressed to slide the hub bodies inwardly to separate the locking pins from the pivot adjustment holes to allow the hub to rotate, thereby allowing the faceplate to pivot. When the buttons are released, the hub bodies slide outwardly to insert the locking pins into the same or different pivot adjustment holes to prevent the hub from rotating.

Abstract: An apparatus for supporting a user includes a faceplate, an arm, and a base. The faceplate has an opening to receive a user's face. The arm is attached to the faceplate and the base. The base includes a base slide that is slidable within a slot of a base body. The base slide includes one or more lock pins that releasably engage one of multiple holes in a lock bar. The lock bar is mechanically coupled to a button body. When the button body is pulled distally, the lock bar moves away from the base slide such that the lock pin(s) is/are removed from the corresponding hole(s) to allow the base slide to slide within the slot. When the button body is released, the lock bar moves towards the base slide such that the lock pin(s) is/are inserted into the same or different hole(s) to lock the slide's position.

Abstract: A electric circuit includes a connection to a current source, an electric load, and a thermal-mechanical fuse which, in the case of failure at an excessive heat emission, interrupts the current supply to the load, which is effectuated by a feeder in which is arranged a spring having two ends, at least one end is soldered to a solder point provided in the feed line. The one solder point is under a mechanical pretension caused by the restoring force of a spring, that separates the solder joint between the spring and the solder point in the feed line, when the solder melts at the solder point.

Abstract: A simplified and economical power supply for redundant computer systems of control systems is disclosed. These control systems may include burner control for furnaces. The safety and reliability of the system are increased. The power supply comprises one single common voltage supply in the form of a self-monitoring power pack unit SN having a power pack NT, an undervoltage monitor UW and an overvoltage monitor. The self-monitoring power pack unit communicates with the redundant computer units P1, P2 via a supply line 1e. This single self-monitoring power pack unit is used according to the invention instead of the known fully parallel two-channel operation with two computer units and two power packs with appertaining components and supply lines. The overvoltage monitor UW and the undervoltage monitor UW are preferably checked for operability through the periodic transmission of a test signal.

Abstract: An indicating arrangement for a distance warning system in motor vehicles which are equipped with measuring and evaluating devices for determining the distance of the vehicle to an obstacle disposed in front thereof and for determining the approach velocity to this vehicle; a desired value is thereby derived from the determined values for the brake deceleration necessary for the avoidance of a collision and an actual value is determined from the actual deceleration values attained during the braking operation whereby only the difference or the ratio of desired and actual value is thereby indicated to the driver.

Abstract: An installation for controlling a measuring beam and/or a light beam in motor vehicles, in which at least one measuring and/or light beam transmitted from the vehicle serves for measuring the distance or illuminating objects which are located ahead of the vehicle in its own lane; measuring devices are thereby arranged in the motor vehicle which determine at least the vehicle velocity and the transverse acceleration as well as possibly the longitudinal acceleration or deceleration for correcting the assumed theoretical braking action and, under certain circumstances, still other relevant vehicle magnitudes; the beam transmitter is then controllable as regards the beam range and/or beam opening angle and/or angle deviation of the beam with respect to the vehicle longitudinal axis by a computer as a function of these measured values.
