Patent SE-510445-C2 (SE)
Inventor: UNLAND STEFAN
IPC: F02B37/18
Filed: 1996-01-24
Abstract: A system for controlling the charging of an internal combustion engine contains an integral controller. If appropriate, a proportional controller and/or a differential controller may also be present. The integration, carried out by the integral controller, of the control error is limited to a prescribable limit value in order to avoid severe overshoots. Various limit values for steady-state operating states and for dynamic operating states can be prescribed. The dynamic limit value can be provided with corrections as a function of characteristic operating variables and with an adaptive correction and can be additionally increased by a safety interval.

Abstract: The present invention relates to a private telecommunication network (10) comprising at least two mobility servers (12, 14, 16), one such mobility server and a server. The invention also relates to methods of updating home node for a cordless terminal (30), registering said terminal as well as finding out where to page, setting up a call to and updating the location of said cordless terminal. Each cordless terminal has an identity. Each mobility server acts as a home node for a part of the cordless terminals in the network, irrespective of the identity of these cordless terminals. The network has a table (46) for registering the home node (12, 14, 16) of all cordless terminals and their identities. The methods all use this table for changing and registering home node as well as for paging and updating the location of a cordless terminal.

Abstract: A method and a device for controlling an electric motor arranged to serve as drive source for electrically driven hand tools or stationary machines, which during operation are made subject to varying loads. According to the invention are limit values, determined by experience and/or calculations, relating to supplied power with regard to different rotary speeds stored in one or a number of memory circuits and compared to present actual rotary speed and supplied power with use of a microprocessor. An output signal from the microprocessor is used to adjust supplied power within preset limits for each rotary speed as compensation for reductions in rotary speed due to increased load and increases in rotary speed due to reduced load. Over- or understepping stored limit values during a predetermined time period set for each group of limit values being arranged to cause disconnection of the drive voltage fed to the electric motor. Furthermore, the start operation comprises preferably of two or more during which the microprocessor step by step increases supplied power and performs comparison between to the microprocessor supplied information relating to obtained rotary speed and stored information relating to expected rotary speed for each step. A rotary speed lower than stored speed information during a predetermined time period being arranged to cause disconnection of the drive voltage fed to the electric motor.

Abstract: To secure an ADSL connection between a first ADSL transceiver (4) in a central office and a second ADSL transceiver (5) on a subscriber's premises on a telephone line (1) between a SLIC (2) in the central office and a telephone (3), a request to the SLIC (2) to apply a ringing signal to the telephone line (1) is detected. In response to such detection, the first ADSL transceiver (4) switches from a normal bit rate to a lower bit rate for the ADSL connection, and orders the second ADSL transceiver (5) to do the same before the ringing signal is applied. In response to an off-hook condition, the lower bit rate is maintained for the ADSL connection. In response to an on-hook condition after the off-hook condition as well as in response to a disappearance of the ringing request without an off-hook condition, the first ADSL transceiver (4) switches back to the normal bit rate and orders the second ADSL transceiver (5) to do the same.
