IPC: H02J7/02
Filed: 1999-05-05
Abstract: A device and a process for charging of rechargeable NiCd, Ni-metal hydride or lithium batteries (12) of implants by transcutaneous transmission of electric power from an external power transmission part (11) to a power receiving part (10) which forms a part of the implant. The charging device is provided with a charging current detector (27, 32, 34) which, in a first charging phase (T1), allows a relatively high charging current (I L) to flow and which, after the cell voltage (U2) of the battery has reached a predetermined limiting charging voltage (U G), in a second charging phase (T2), reduces the charging current as compared to the charging current which flows at the end of the first charging phase. The charging current detector is made such that, during the second charging phase, it sets the charging current to a value causing the cell voltage during the second charging phase to be kept at least approximately at a predetermined constant voltage value (U G).

Title: Secure packet radio network
Inventor: LARSEN MARK SIEVERT
IPC: H04L9/00
Filed: 1998-02-09
Abstract: A packet radio network comprises at least one network operator station and a number of user stations. The user stations transmit message data to one another, either directly or via intermediate stations. When stations are first activated, they transmit key request messages to the network operator station. Other, authenticated stations in the network will not communicate with the new station, but will pass the key request message to the network operator station. The network operator station transmits the necessary keys back to the new station via the other stations to permit the new station to operate. Each user station transmits key probe signals from time to time which advise other stations of its public key.
