Patent number: 9248446
Abstract: A disposable blood separation set and a centrifugal blood processing system comprising a blood processing chamber adapted to be mounted on a rotor of a centrifuge; a frustro-conical cell separation chamber in fluid communication with the processing chamber, the cell separation chamber having an inlet, an outlet and a gravity valve inside the cell separation chamber. The valve is responsive to the gravitational field created by the speed of the rotor. When the rotor spins at high speed, the gravity valve may open the outlet at a location proximal to an axis of rotation of the rotor. When the rotor spins at a lower speed, the gravity valve may open the outlet at a location distal from the axis.

Patent number: 9212989
Abstract: A chemical composition analyzer may be used to optically determine and report chemical compositions associated with gases within a gas collection and transmission infrastructure. This analyzer includes a number of optical sensors which may be used to perform spectroscopic spectrographic analysis in order to determine the chemical composition of the gas. Additionally other sensors may be used to measure other physical properties associated with the gas. These sensors are tied to a data collection system wherein the output of the optical sensors and sensors used to measure the physical properties of the gas may be combined and processed in order to determine in a nearly continuous fashion the chemical composition associated with the gas at various locations within the gas collection and transmission infrastructure. This real time compositional analysis may be used to determine valuations of the gas or to optimize other processes or equipment configurations.

Patent number: 9194777
Abstract: A filter test strip to filter and test a specimen in liquid includes a test element and a specimen filter assembly which is located on the test element and includes a filter cotton holding layer, a filter cotton layer and a cotton bonding layer. The filter cotton holding layer has a filter channel to allow the specimen in liquid to pass through. The filter cotton layer fills the filter channel. A gap is formed between the filter cotton holding layer and filter cotton layer. The cotton bonding layer is located below the filter cotton holding layer and bonded to the test element via an adhesive which masks the gap. Hence the specimen in liquid can be prevented from seeping out through the gap with passing through the filter cotton layer. Therefore, the specimen in liquid can fully be filtered by the filter cotton layer to enhance test accuracy.

Patent number: 9182324
Abstract: Systems and methods in accordance with embodiments of the present invention allow for the automatic control and scheduling of a staining apparatus for biological samples on slides present within the apparatus. In some embodiments, the actions of a robot coupled to the staining apparatus, which performs some of the staining tasks on the individual slides in accordance with their respective protocols, may be prioritized and scheduled. In some embodiments, the scheduling may result in increasing or maximizing the throughput of slides. In some embodiments, robot scheduling ensures that the individual slides are processed substantially within the tolerances specified by their respective protocols. In some embodiments, the robot scheduler may respond to spontaneous user actions and adaptively schedule or re-schedule robot actions.

Patent number: 9176062
Abstract: A luminescence sensor, comprising a non-transparent substrate structure (2) having at least one aperture (5) intended to comprise an analyte and a transparent substrate structure (3), which is arranged to or adjacent said first structure (2). The aperture has a smallest lateral dimension, which is smaller than half the effective wavelength of an excitation radiation, such as light at a wavelength of 700 nm, resulting in an effective wavelength in water of about 538 nm. The transparent structure has a trench (4) with a surface portion provided with ligands with an affinity towards a target molecule. The trench results in that a luminophore attached to the target molecule will be positioned at the entrance surface of the aperture, where the excitation energy is largest.
