Publication number: 20160245838Abstract: A mixing vial is provided for an automated biological reaction apparatus typically used for staining tissue samples in Immuno-histological and in-situ hybridisation reactions. The mixing vial allows reagents placed on the apparatus to be mixed together to form additional or blended reagents. A reagent dispenser mounted on a robotic arm withdraws reagent from the reagent containers and deposits it into one of the mixing vials. Several reagents can be deposited into each vial. Mixing is undertaken by withdrawing the reagents in a vial and re-dispensing the reagent back into the vial. Mixing may take place between the operation of other tasks performed by the apparatus, and a scheduler is used to ensure blended reagent is provided before it is required in one of the processes undertaken on the apparatus. The apparatus is able to automatically identify which blended reagents are required and when they must be applied to provide an appropriate schedule that minimises time taken to stain samples.Type: ApplicationFiled: April 12, 2016Publication date: August 25, 2016Applicant: LEICA BIOSYSTEMS MELBOURNE PTY LTDInventors: Frank SAMUHEL, Adam DONATH, Krzysztof ZAWADZKI, Anthony Cecil WHITE

Patent number: 8315899Abstract: A method and apparatus for scheduling are disclosed. The apparatus applies tests to microscope slides, where the slides are loaded in trays. Each tray is treated as a batch, and batches may be interleaved to reduce the total running time of testing all slides in up to three batches. The batches of slides have protocols that define the application of reagents such as primary antibodies. The protocols define open times, where no common resources are used, and use times, where common resources are used. The scheduler operates to ensure that the use times between batches does not overlap, without leaving the next step in the protocol for an excessive period of time.Type: GrantFiled: February 24, 2004Date of Patent: November 20, 2012Assignee: Leica Biosystems Melbourne Pty LtdInventors: Frank Samuhel, Stuart Lucas, Christopher Bowen

Patent number: 7708697Abstract: Airway monitoring apparatus 30 includes a driver 6 for applying sound in the audible frequency range to the airway of a subject and a detector 7 for monitoring the response of the airway, e.g. by detecting transmitted sound signal components and/or reflected sound signal components. Variations in the detected sound signal, e.g. energy, due to attenuation of the signal, give an indication of the state of the airway, e.g. airway patency, and can be used to monitor sleep-disordered breathing events, such as apnea and hypopnea, and to provide a breathing event index, e.g. AHI. The apparatus may provide servo-control for a respiratory assist device, such as a positive airway pressure device, so as to provide an appropriate pressure level setting. It may allow for home use of such devices and for home titration. It may also assist in discriminating central and obstructive breathing events, and in providing a measure of airway resistance.Type: GrantFiled: April 15, 2005Date of Patent: May 4, 2010Assignee: Pulmosonix Pty LtdInventors: Malcolm Howard Wilkinson, Clive Andrew Ramsden, Philip John Berger, Peter Camilleri, Jacqueline Anne Wilson, Frank Samuhel
