Patent number: 11220414Abstract: A stabilizer leg arrangement with a stabilizer leg (25), which is extensible by a hydraulic cylinder (27) into a supporting position in contact with the ground. A piston (32) divides the internal space of the hydraulic cylinder into first and second chambers (34, 35), wherein these chambers are configured to come into fluid communication with each other through a flow channel (41) in the hydraulic cylinder when the piston reaches an advanced end position and abuts against a stop surface. An electronic control device (72) is configured to establish information as to whether or not the stabilizer leg is in the supporting position while taking into account a measuring value (V1) related to the hydraulic pressure in the first chamber (34). The invention also relates to a corresponding method and a mobile working machine comprising such a stabilizer leg arrangement.Type: GrantFiled: December 20, 2019Date of Patent: January 11, 2022Assignee: Hiab ABInventors: Erik Nylander, Mats Lindström, Lars Rydahl

Patent number: 8699502Abstract: A media receiver hub receives wireless signals from multiple sources (e.g., satellite signals from multiple satellites) and provides the signals to end devices over a local network. According to an example embodiment, a satellite hub is responsive to channel input selections received from end devices by selecting channels from within received satellite signals, and by converting each channel into a format amenable for delivery to and use at an end device requesting the channel. The converted channels are communicated to the end devices over a network that also facilitates communications between the devices, by restricting the communications to using a portion of the available bandwidth of the network, reserving bandwidth for communications with and/or between the end devices (or other network devices).Type: GrantFiled: March 16, 2009Date of Patent: April 15, 2014Assignee: Entropic Communications, Inc.Inventors: Abraham Krieger, Laurence Alan Strong, Mats Lindstrom, Sadashiv Vinayak Phadnis, Yoav P.

Patent number: 8107914Abstract: Radio-frequency (RF) circuits, methods and systems are implemented according to a variety of embodiments. According to one such embodiment, a radio-frequency (RF) receiver circuit is implemented with an adjustable RF filter circuit in a receive path of the RF receiver circuit. A local oscillator (LO) generates a LO signal and an RX_LO signal from the LO signal. A mixing circuit mixes a signal received from the adjustable RF filter circuit and the RX_LO signal. An intermediate-frequency (IF) circuit generates an IF_cal signal at the receiver circuit. A calibration circuit implements both a calibration mode and a receive mode. In the calibration mode, a calibration signal is injected into the receive path. A setting of the adjustable RF filter circuit is determined. In the receive mode, the calibration circuit disables the injection of the calibration signal into the receive path of the RF receiver circuit.Type: GrantFiled: December 16, 2008Date of Patent: January 31, 2012Inventors: Daniel Firoiu, Damian Costa, Mats Lindstrom, Kendal McNaught-Davis Hess, Weinen Gao
