Abstract: A method includes providing a first electrode and a second electrode, receiving a first plurality of signals from the first electrode during a first period of time, and receiving a second plurality of signals from the second electrode during a second period of time. The method also includes receiving a pooled signal comprising a third plurality of signals from the first electrode and a fourth plurality of signals from the second electrode and isolating, from the pooled signal, one or more of the third plurality of signals and one or more of the fourth plurality of signals.

Abstract: Spatial exploration systems and methods of spatial exploration utilizing spatial sound in accordance with various embodiments of the invention are disclosed. In one embodiment, a spatial exploration system acquires sensor data and constructs a 3D spatial model of a surrounding real world environment. The system can instantiate a 3D object at a location within the 3D spatial model corresponding to the location of a real world feature, determine a location and orientation of a user within the 3D spatial model, and generate an audio clip containing vocalized information describing the feature. The spatial exploration system can then output a spatial sound describing the identified feature by modifying an audio clip based upon the position of the 3D object relative to the location and orientation of the user within the 3D spatial model to encode audio cues as to the location of the feature in the surrounding real world environment.

Abstract: A cardiac assistance, device has a supporting component, which surrounds the heart and on the inside of which a plurality of adjacent inflatable and deflatable chambers are provided, via which an inside wall can be displaced inward. The chambers have a fluidic connection to at least one pump via lines. A plurality of supply valves on the supply side are arranged between the pump and the chambers. Some individual chambers or groups of chambers are assigned dedicated supply valves, in order to drive the chambers individually or in groups.

Abstract: A heart support system featuring a sheath sized to fit about at least a portion of an adult human heart in a living body, an expansion sleeve disposed within the sheath and sized to fit about the heart and a sensor sleeve disposed within the sheath and sized to fit about the heart. The expansion sleeve is at least partially defining an expandable chamber. The sensor sleeve carries at least one sensor electrically responsive to a heart parameter.

Abstract: The invention relates to a cardiac assistance device having a supporting component (14) which surrounds the heart and on the inside of which a plurality of adjacent inflatable and deflatable chambers (126, 226, 326) are provided, via which an inside wall can be displaced inward, the chambers (126, 226, 326) having a fluidic connection to at least one pump (80) via lines. A plurality of supply valves on the supply side are arranged between the pump (80) and the chambers (126, 226, 326). At least individual chambers (126, 226, 326) or groups of chambers (126, 226, 326) are assigned dedicated supply valves, in order to drive the chambers (126, 226, 326) independently individually or in groups.

Abstract: An inflatable head protection system for occupants of a motor vehicle is provided which has an air bag which is inflated laterally of the head in the event of a side impact and prevents the displacement of the head. The head protection system has a belt guiding duct, the belt strap of a seat belt extending through this belt guiding duct. In order to be able to follow the belt strap movements, the head protection system is swivellably fastened by way of a ball joint on the upper edge of a seat backrest.

Abstract: A head protection system for occupants of a motor vehicle has a multi-chamber air bag, which is inflated laterally of the head in the event of a side impact and prevents the displacement of the head. In addition, it protects the head from vehicle body parts that penetrate the occupant department. Via the individual chambers, an L-shape of the air bag can be constructed which is optimal for the desired purpose. In addition, the division into several chambers permits longer and therefore less aggressive inflation times.

Abstract: An inflatable seat belt for securing an occupant in a motor vehicle having a belt strap which is divided by way of a belt latch into a diagonal region resting against the occupant's upper body and into a horizontal region resting against the occupant's pelvis. A belt buckle is fastened to the vehicle and the belt latch is detachably connectable with the belt buckle. On the diagonal region of the belt strap, an air bag is mounted which extends from the occupant's upper body to behind the head. The air bag is made of a material which is shortened in an axial direction during inflation. The diagonal region of the belt strap is connected with an upper retractor fastened to the vehicle, and the horizontal region of the belt strap is connected with a lower retractor fastened to the vehicle.
