Patent number: 10054531Abstract: There is provided a method of measuring a sedimentation parameter of suspensions or precipitants in a fluid medium sample, said method compromising providing at least one micro-cantilever sensor, said micro-cantilever sensor comprising at least two materials having different coefficients of thermal expansion, and having a heater and piezo-resistive sensor integrated therein, pulsing the heater with one or more electrical pulses to induce heat generation in the micro-cantilever, sampling the output of the integrated piezo-resistive sensor to characterize a response of the micro-cantilever during sedimentation in the fluid medium sample, and determining a value of the sedimentation parameter from the characterized response. There is also provided an apparatus arranged to carry out the method.Type: GrantFiled: March 12, 2013Date of Patent: August 21, 2018Assignee: Microvisk LimitedInventors: Richard John Dunn, Lois Bello Fernandez De Sanmamed, Robert Henry Ibbotson, Vladislav Djakov

Patent number: 8607619Abstract: A device for detecting a property of a fluid includes a body region and a flexible element having a first end and a second end. The first end is fixedly located on the body region. The flexible element is arranged to move from at least a first configuration to a second configuration via bending of the flexible element. The flexible element includes an actuating portion arranged to move the flexible element between the first configuration and the second configuration. The device also includes a movement detector for detecting movement of the flexible element.Type: GrantFiled: August 25, 2011Date of Patent: December 17, 2013Assignee: Microvisk LimitedInventors: Vladislav Djakov, Ejaz Huq, Paul Vernon

Patent number: 8297110Abstract: A device for measuring the properties of a fluid, a method of manufacture, and a method of operation is described. The device includes a body region, a first flexible element and a second flexible element. Each flexible element has a first end and a second end, the first end being fixedly located on the body region. Each flexible element is moveable from at least a first respective configuration to a second respective configuration via bending of the element. The first flexible element includes an actuating portion arranged to move the flexible element between the first configuration and the second configuration. The second flexible element includes an integral movement sensor for sensing movement of the flexible element. The first flexible element is coupled to the second flexible element at a position distant from the body region. Only the actuating portion of the first flexible element is operable to move the first and second flexible elements.Type: GrantFiled: March 14, 2007Date of Patent: October 30, 2012Assignee: Microvisk LimitedInventors: Vladislav Djakov, Ejaz Huq, Richard John Dunn
