Patent number: 11690169Abstract: A thermal management system that include an electronic circuit boards having at least two circuit boards with a space in between and further includes one or more air tubes or conduits. The electronic circuit board and air tubes are configured for drawing air into the space to facilitate cooling of the electronic circuit board concurrent with cooling of a heat sink of a heat pump connected with the electronic circuit board. The system can further include a partition to isolate airflow from the heat sink from airflow through the electronics circuit board, and can further include one or more interface components for maintaining isolation and control of air flow, improving air intake and/or supporting auxiliary components.Type: GrantFiled: June 16, 2022Date of Patent: June 27, 2023Assignee: Bio-Rad Laboratories, Inc.Inventors: Amir Sadri, Neven Nikolic, Gabriel Culinco, Thanh-Vi Tran, Nenad Kircanski

Patent number: 8798950Abstract: A system for controlling an ultrasonic transducer utilizes an indication of the relative phase of the voltage on the transducer and the current passing through the transducer to control the relative phase to a value that has been preselected to correspond to resonance of an electromechanical system that includes the ultrasonic transducer. In one example application, the system includes a waveform generator that produces an oscillating signal, and the frequency of the oscillating signal is adjustable under control of the control processor. The control processor adjusts the frequency of the oscillating signal according to a proportional control law at least some of the time, and according to a proportional-integral control law at least some of the time. The control processor may also control the amplitude of the oscillation of the ultrasonic transducer.Type: GrantFiled: August 20, 2010Date of Patent: August 5, 2014Assignee: Bio-Rad Laboratories, Inc.Inventors: Neven Nikolic, Manja Kircanski, Nenad Kircanski, Amir M. Sadri, Milija Timotijevic, Zhiliang Xu

Publication number: 20110130560Abstract: A cartridge in which sonication is applied to biological matter to disrupt and release nucleic acids from the matter is formed from a cartridge body containing a series of wells connected by fluid passages engineered to prevent backflow, with at least one well containing a sonication window covered by a thin lamina to transmit sonic vibrations from a sonication horn contacting the exterior surface of the window. Fluid transport among the wells is achieved by pressure differentials through the fluid passages, and a succession of functions is performed in the various wells, including disruption, mixing, binding of the released nucleic acids to binding materials, washing, elution, and collection.Type: ApplicationFiled: May 27, 2010Publication date: June 2, 2011Applicant: BIO-RAD LABORATORIES, INC.Inventors: Amir M.
