Abstract: A hydraulic master apparatus, in particular, for a hydraulic brake or clutch of handlebar-guided vehicles with a lever, which is pivotally mounted in a support, and a hydraulic cylinder, which can be disposed in a handlebar tube of the handlebar-guided vehicle and has a piston movably disposed therein, wherein a central valve is disposed in the piston.

Abstract: A technique for controlling and compensating the energy spread of a charged particle beam is provided. This technique is based on a passive dielectric-loaded structure that redistributes the energy within the bunch by means of the wakefield generated in the structure. Cylindrical and planar structure configurations are provided and also means for electrical and mechanical tuning to optimize performance. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Embodiments of the invention provide a system and a method for monitoring alertness of an operator. At least one continuous wave radar device can be used to detect an indicator of a biological parameter for the operator. A value for the biological parameter can be determined based upon the detected indicator. A level of alertness of the operator can be determined based upon the determined value for the biological parameter.

Abstract: Embodiments of the invention provide a system and a method for controlling environmental conditions of an enclosure for animals. At least one radar device can be used to detect an indicator of a biological parameter for at least one of the animals. A value for the biological parameter can be determined based upon the detected indicator. Operation of environmental management equipment for the enclosure can be controlled based upon the determined value for the biological parameter.
