20100274323 | METHOD AND SYSTEM FOR POWER MANAGEMENT - Telemetry data from an IMD are routinely extracted in order to perform a full prognosis of a patient's condition and to alter the IMD therapy programming if necessary. Typically, while the IMD is inside of the patient, it periodically or continuously collects and stores data into its memory. These stored data can then be extracted by a physician to an external device for further analysis. In addition to the stored telemetry data, the physician may also want to collect real-time telemetry data such as real-time IEGM data or other physiological data while the patient is in the physician's office. However, transmitting telemetry data can consume a high level of power and shorten the battery life of the IMD if not properly managed. Thus, it is advantageous to have built-in features to minimize the possibility the IMD is not transmitting and/or receiving data while it is not being monitored and/or used by the physician for a predetermined amount of time. | 10-28-2010 |

20080258443 | Safety Arrangement for Use in a Motor Vehicle - A safety arrangement to provide protection for an occupant in a motor vehicle includes a seat-belt provided with a measuring device to measure energy absorbed by the seat-belt. The measuring device may determine the length of safety-belt paid-out after a retractor locks, the belt being paid-out against a force provided by a force-limiter. The energy absorbed is calculated and is used to control the vents of a ventable air-bag. The air-bag is vented if a substantial part of the energy of the occupant is absorbed by the seat-belt, but is not vented if a large proportion of the energy has not been absorbed by the seat-belt. | 10-23-2008 |
