Patent number: 11281975Abstract: A method for creating one or more machine learning models in a model training engine is provided. The method includes providing to a user, via a graphical user interface, a selection of components for a machine learning model, at least one component having a computational layer including one or more coefficients associated with a component attribute. The method also includes displaying, in the graphical user interface, a component selected by the user, including a selected value of the component attribute and executing the machine learning model with a training archive as an input, to obtain an output indicative of a desired feature of the training archive. The method also includes comparing the output with a desirable feature value, and modifying at least one coefficient in the component of the machine learning model based on a difference between the output from the machine learning model and the desirable feature value.Type: GrantFiled: September 24, 2019Date of Patent: March 22, 2022Assignee: PerceptiLabs ABInventors: Martin Isaksson, Robert Erik Lundberg

Patent number: 10708224Abstract: A controlling unit retrieves information regarding system interconnect topology and assigns unique address to all connected units without the need for any prior configuration. An added unit with cascading ports will be able to use the address assignment that enables the controller to avoid address collisions between connected units. In short, the disclosure provides the system of interconnected units with a “plug and play” capability.Type: GrantFiled: September 30, 2015Date of Patent: July 7, 2020Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Jan-Erik Lundberg, Curt Olsson

Patent number: 10587148Abstract: Disclosed is a power supply unit, PSU, for wirelessly powering components of a radio base station, RBS, such as a radio unit, RU, transmission units (TMR) and a baseband digital unit, BDU. The PSU includes a TX coil for generating an energy field that is used to induce a current and voltage in an RX coil that is part of a component of the base station. The need for power cables, which are inefficient at transferring energy, is therefore greatly reduced. Hence, the energy efficiency of the RBS is increased.Type: GrantFiled: April 27, 2015Date of Patent: March 10, 2020Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Lackis Eleftheriadis, Per Eklund, Jan-Erik Lundberg

Patent number: 5881376Abstract: Methods and systems for calibrating transceivers are described. Analog transceiver components create errors, such as gain and offset errors in a receiver or a transmitter portion, which are compensated by adjusting digital signal processing in the computing portion of the transceiver. Errors can be measured in a calibration procedure and determined compensating values stored in a memory device of the transceiver. These values can then be retrieved when the transceiver is initialized for usage during signal processing of signals received by and transmitted by the transceiver.Type: GrantFiled: December 15, 1995Date of Patent: March 9, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Jan-Erik Lundberg, Anders Staaf

Patent number: 5878342Abstract: Methods and systems for estimating Supervisory Audio Tone (SAT) strength during data transfer and for a short time period thereafter. The SAT during this period is regarded as being identical to the strength measured just before the data transfer was started. In an alternative embodiment, a probabilistic algorithm can be used wherein previous measurements are used to predict the SAT strength during and for a period after data transfer. Where the present invention is used in a mobile radio telecommunications system of the type in which analog information is transmitted between at least one base station and a number of mobile stations, a method for supervising the quality of a connection between the base station and a mobile station includes transmitting data between the base station and the mobile station during which a SAT is not transmitted and using pre-data transfer SAT measurement for radio transmission quality supervision during at least a time period of said data transmitting step.Type: GrantFiled: December 15, 1995Date of Patent: March 2, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Karl Fredrik Robert Gustafson, Sven Gunnar Johnny Lidfors, Jan-Erik Lundberg, Lars Peter Wahlstrom

Patent number: 5860418Abstract: A method of verifying function and status of breathing equipment, wherein the breathing equipment includes a gas supply, a closure valve on the gas supply, a primary pressure regulator downstream of the closure valve, a pressure sensor, a secondary pressure regulator downstream of the primary pressure regulator, a breathing mask downstream of the secondary pressure regulator, an indicator, a processor connected to the pressure sensor and the indicator, and gas lines between the gas supply, the primary pressure regulator, the secondary pressure regulator, and the mask. A processor for receiving sensed data, comparing the sensed data to control values, and producing an output signal is activated. At least one functional or status variable within the equipment is measured. The at least one measured value is compared to a corresponding control value with the processor. An output signal based upon the comparison is produced.Type: GrantFiled: January 17, 1997Date of Patent: January 19, 1999Assignee: Comasec International S.A.Inventor: Mats Erik Lundberg
