Granted: 2009-03-10
Abstract: A method of constructing a cardiac map of a heart having a heart cycle including bringing an invasive probe into contact with a location on a wall of the heart; determining, at at least two different phases of the heart cycle, a position of the invasive probe; and determining a local non-electrical physiological value at the location. The method is repeated for a plurality of locations in the heart. The positions are combined to form a time-dependent map of at least a portion of the heart and local relationships between changes in positions of the invasive probe and determined local non--electrical physiological values are determined.  Preferably, local electrical activity at the plurality of locations is also acquired.

Title: Apparatus for emplacing a fastening element into a placement base, and use of the apparatus
Inventor: WEIHRAUCH ACHIM
IPC: B25C7/00
Filed: 1998-11-23
Granted: 2007-01-30
Abstract: The invention relates to a device for driving fastening elements into a base for the purpose of fastening structural components. Said device has a working piston whose range of acceleration and deceleration can be adapted to different conditions whilst maintaining an optimal driving depth (31) and minimal piston length (32). This applies to mechanical, pyrothechnicai, pneumatic, electromagnetic and electrothermal working piston drive mechanisms. These devices can be configured for manual use or for production robots, and are characterised mainly in that the working stroke is limited by a piston sleeve (35) which is connected to the piston plate (11), a land (39) which is connected to a ring element (38) or a combination of the two. A chamber is therefore formed on the piston plate side (48a) and the ring side (48b). Said chamber accommodates an e.g. mechanical return device (8) which is subjected to its own load only during the driving-in and gauging processes. The remaining piston energy is cushioned by a buffer (30). The modular configuration of the piston plate (11) and the piston shaft (10) means that the components can be optimised independently in terms of shape and material. The piston mass can be varied considerably. The device can be configured with any degree of rigidity and can be adapted to different fastening elements, bases and driving-in conditions.

Abstract: Communication units (107 and 109) are distinguished between preferred units and non-preferred units. The same message content is transmitted (207) to the preferred units at a preferred quality, such as at a preferred transmission rate, and to the non-preferred units (209) at a non-preferred rate, such as one-half the preferred transmission rate. The bandwidth saved can be reallocated for other messages, thereby resulting in a more efficient use of resources for a dispatch call.
