Publication number: 20230420466Abstract: Infrared (IR) photodetecting systems and methods. A system may comprise at least one photosite having a Ge photosensitive area (GPSA) that includes an absorber doped area having a first polarity and a Si layer comprising a first doped area (FDA), a storage well (SW), a floating diffusion (FD) and a transfer gate (TG); a controllable power source (CPS); and a controller, operable to control the CPS and the TG, to concurrently provide at a first time controlled voltages to the GPSA, FDA and FD, thereby forcing charge carriers of a given polarity (CCGP) from the GPSA toward the SW and to provide at another time other voltages to the GPSA, FDA and FD, thereby diminishing the forcing of the CCGP toward the SW and ceasing collection of signals by the SW, and to intermittently transfer the CCGP from the SW via the TG to the FD, where the CCSP are read via an electrode coupled to the FD.Type: ApplicationFiled: November 27, 2021Publication date: December 28, 2023Inventors: Eran Katzir, Matan Assaf, Omer Kapach, Avraham Bakal, Uriel Levy

Patent number: 8545420Abstract: The invention relates to a rehabilitation device which guides a patient to perform a motion with a correct spatial trajectory, by the device applying one or more pushing, assisting, reminding, responding and/or resisting forces during a motion (or intent to move) by the patient. The forces are applied by an actuator, for example, a robotic articulated arm or a spherically jointed lever. The applied forces act as a force fields, optionally continuous, which impeded and/or guides a patient. The device can be programmable with various trajectories (paths and/or velocities) and/or forces. The forces at one point in the trajectory can vary responsive to an actual trajectory by the patient and/or responsive to a rehabilitation plan and/or improvement of the patient. The device can learn a motion entered by a physiotherapist and replay it for the patient.Type: GrantFiled: February 4, 2005Date of Patent: October 1, 2013Assignee: Motorika LimitedInventors: Omer Einav, Haim Einav, Benny Rousso, Doron Shabanov, Eran Katzir, Gad Binyamini

Patent number: 6622099Abstract: A built-in auto-tuning system of a motor control system provides an auto-tuning of the motor control system. The built-in tuning system generates and applies a random noise test signal to the controller. In response to the test signals, the tuning system obtains response data such as the gains and phases over a wide range of operating frequencies. Based on the received data, the tuning system generates an open-loop Bode plot of the control system. The tuning system then calculates the phase and gain margins of the control system. The calculated gain and phase margins are compared with a set of predetermined values by the tuning system to automatically adjust the compensation parameters of the motor control system for a stable operation.Type: GrantFiled: June 5, 2001Date of Patent: September 16, 2003Assignee: Kollmorgen CorporationInventors: Ilan Cohen, Eran Katzir, Oren Kidron
