Appl. No.:

09/288145

John Rivera - Aurora CO 80015

International Classification:

US Classification:

604 602, 494 43, 494 37, 604 401, 604 611, 604 601, 422 44, 210782

Abstract:

The present invention is a blood separation system that is fully mechanized to collect blood from a patient, separate waste portions of the blood, wash the blood, and redirect the usable portions to a device for reinjecting the usable portions into the patient. The present invention prevents accidental activation of an improper operation that could cause harm to a patient or a shut down of the system by requiring confirmation of each step by an operator. The invention provides screen displays with detailed setup instructions, eliminating the need for secondary documentation that might not be allowed in a surgical environment. The invention also instructs the operator at the appropriate times to do certain manual steps such as opening and closing clamps. Since the opening and closing of clamps is a highly critical operation, confirmation of these steps is also required. A method and suitable apparatus is also disclosed for sequestration of platelet rich plasma whereby a blood sample is spun at a high speed sufficient to separate solid cells from the blood sample and spun at a lower speed for a predetermined time to allow platelets to elute from the solid cells.

The system provides screen displays with detailed setup instructions and instructs the operator at the appropriate times to do certain manual steps. Apparatus for sequestration of platelet rich plasma spins at a high speed sufficient to separate solid cells from the blood sample and then spins at a lower speed for a predetermined time to allow platelets to elute from the solid cells.

International Classification:

G11C 11/00

US Classification:

365158, 365171

Abstract:

A method and system for programming a magnetic memory is disclosed. The method and system further include turning on a word line current and turning on a bit line current. The word line current is for generating at least one hard axis field. The bit line current is for generating at least one easy axis field. In one aspect, the method and system further include turning off the word line current and the bit line current such that a state of the at least one magnetic memory cell is repeatably obtained. In another aspect, the word line current is turned off after the bit line current is turned off.

International Classification:

G01R 33/60

Abstract:

A ferromagnetic resonance (FMR) measurement method is disclosed wherein a magnetic film or stack of layers is patterned into elongated structures having a length along a long axis. A magnetic field (H) is applied in two different orientations with respect to the long axis (in-plane parallel and perpendicular to the long axis) or one orientation may be perpendicular-to-plane. In another embodiment, H is applied parallel to a first set of elongated structures with a long axis in the x-axis direction, and perpendicular to a second set of elongated structures with a long axis in the y-axis direction. From the difference in measured resonance frequency (Δfr) (for a fixed magnetic field and sweeping through a range of frequencies) or the difference in measured resonance field (ΔHr) (for a fixed microwave frequency and sweeping through a range of magnetic field amplitudes), magnetic saturation Ms is determined using formulas of demagnetizing factors.

G01N 24/00

Abstract:

A scanning ferromagnetic resonance (FMR) measurement system is disclosed with a radio frequency (RF) probe and one or two magnetic poles mounted on a holder plate and enable a perpendicular-to-plane or in-plane magnetic field, respectively, at test locations. While the RF probe tip contacts a magnetic film on a whole wafer under test (WUT), a plurality of microwave frequencies (f) is sequentially transmitted through the probe tip. Simultaneously, a magnetic field (H) is applied to the contacted region thereby causing a FMR condition in the magnetic film for each pair of (H, f) values. RF output signals are transmitted through or reflected from the magnetic film to a RF diode and converted to voltage signals which a controller uses to determine effective anisotropy field, linewidth, damping coefficient, and/or inhomogeneous broadening for a sub-mm area. The WUT is moved to preprogrammed locations to enable multiple FMR measurements at each test location.

G01R 33/345

Abstract:

A ferromagnetic resonance (FMR) measurement system is disclosed with a plurality of “m” RF probes and one or more magnetic assemblies to enable a perpendicular-to-plane or in-plane magnetic field (H) to be applied simultaneously with a sequence of microwave frequencies (f) at a plurality of “m” test locations on a magnetic film formed on a whole wafer under test (WUT). A FMR condition occurs in the magnetic film (stack of unpatterned layers or patterned structure) for each pair of (H, f) values. RF input signals are distributed to the RF probes using RF power distribution or routing devices. RF output signals are transmitted through or reflected from the magnetic film to a plurality of “n” RF diodes where 1≤n≤m, and converted to voltage signals which a controller uses to determine effective anisotropy field, linewidth, damping coefficient, and/or inhomogeneous broadening at the predetermined test locations.

Abstract:

A housing for an electronic device can include a body having an exterior surface and a second surface disposed opposite the exterior surface at least partially defining an interior volume, the body defining a first repeating pattern of apertures extending from the exterior surface to the second surface. The housing can also include a component defining a second repeating pattern of apertures, the component positioned adjacent to the second surface. The first repeating pattern of apertures and the second repeating pattern of apertures can combine to define an open area of at least about 70%.
