Patent number: 10110641Abstract: A data transfer connection between a device and another device can be established using a basic protocol having a multipath extension that allows for the data transfer connection to use several different paths in parallel. In establishing the data transfer connection, an intermediate device receives a connection request from the device. This connection request comprises an indication that the device is capable of handling the multipath extension. In addition, the connection request comprises an identification of the other device with which the data transfer connection is to be established. The intermediate device then determines whether the other device is capable of handling the multipath extension, or not. The intermediate device establishes the data transfer connection in accordance with the multipath extension if the other device is capable of handling the multipath extension.Type: GrantFiled: December 8, 2014Date of Patent: October 23, 2018Assignee: UNIVERSITE CATHOLIQUE DE LOUVAINInventors: Gregory Detal, Olivier Bonaventure, Christoph Paasch

Patent number: 9807326Abstract: In an image sensor, a front-end circuit provides an output signal indicative of the amount of light in response to at least one input signal. The front-end circuit includes a transistor having a threshold voltage that affects a relationship between the output signal and the level of the detection quantity. This transistor has a biasing node via which a biasing voltage can be applied to a semiconductor region that affects the threshold voltage of the transistor. A replica of the front-end circuit receives at least one defined input signal, among which is a substitute of the detection quantity having a defined level. The replica is arranged in a control loop that controls the biasing voltage that is applied to the biasing node in the replica, so that the replica provides a defined output signal. This biasing voltage is then also applied to the biasing node in the front-end circuit.Type: GrantFiled: January 26, 2015Date of Patent: October 31, 2017Assignee: UNIVERSITE CATHOLIQUE DE LOUVAINInventors: David Bol, Numa Couniot
