摘要:
A blood test instrument using a disposable cartridge and a method of measuring a blood sample using the instrument are disclosed. The instrument includes a cell counting station for counting blood cells by electrical resistance measurement, a pressure actuating component adapted to apply a pressure alternately on two flexible receptacles of a disposable cartridge removably placed in the instrument to cause flowing of a mixture of a blood sample and a liquid agent between the two receptacles to obtain proper mixing, and a conduit adapted to deliver the mixture to the cell counting station for counting. After measuring the blood sample, the instrument withdraws a washing liquid contained in another receptacle of the disposable cartridge and uses the washing liquid to clean the instrument and to deliver the mixture back to the cartridge for disposal.

An aortic stent graft and a method of deploying the aortic stent graft. The method comprises providing a tapered tubular graft having a distal end and a proximal end, providing at least one stent attached to the graft at a site adjacent the distal end of the graft, loading the graft into an introducer, inserting the introducer through an incision in the aorta, deploying the graft inside the aorta; and suturing the proximal end of the graft in place.
摘要:
A system and method for reducing reflections in a transmission line and for recovering energy from the load in the transmission during the process. At least three drive signal levels are utilized. The transition from the second level to the third level during a rising transition and the transition from the second level to the first level during a falling transition is timed to coincide with the arrival of the reflected signal from the immediately-preceding transition. A capacitor is advantageously used as the source for the intermediate drive signal levels and advantageously facilitates energy recovery and conservation.

A filter device has a filter housing, which is intended to contain a liquid to be filtered and in which at least one filter rod is arranged. The filter rod is composed of annular washers, which are arranged in a stack on a core formed with openings and which are so closely packed that particles in the liquid adhere to the periphery of the washers when the liquid is caused, from the outside, to pass between the washers into the core for filtration. The filter device has a gas supply member, which is intended to inject a gas flow into the liquid in the filter housing.In a method of cleaning a filter rod for filtering a particle-containing liquid in such a filter device, a gas flow is injected into the liquid in the filter housing so that a particle sock, which is formed on said filter rod of particles in the liquid, is detached from the filter rod and disintegrated.

A portable battery-operated electronic device authenticates/identifies a charging unit in order to prevent an incompatible and/or poorly designed or constructed charging unit from possibly damaging the portable battery-operated electronic device. The authentication/identification is effectuated over a wireless interface (e.g., using Bluetooth transceivers) when a portable battery-operated electronic device detects connection to a charging unit. The portable battery-operated electronic device requests data related to source and/or compatibility of the charging unit. If data is received and it indicates a proper source and/or compatibility, the portable battery-operated electronic device permits the charging. Otherwise, the portable battery-operated electronic device executes an action, such as preventing charging and/or memorializing information about the risky charging.

Commonly clocked digital storage elements are provided with mutually different clock-to-output delays in order to timewise stagger their respective switching current spikes from one another, thereby “smearing” the aggregate current spike over time.

摘要:
A method and apparatus for minimizing harmonic content in a digital signal driver circuit are disclosed. A digital input signal applied to an input node generates a corresponding digital output in a circuit with two or more MOS devices in cascode connection with each other. The slew rate of leading or trailing edge transitions associated with the output signal are controlled using one or more parasitic capacitances associated with the fabrication of two or cascode connected MOS devices. The two or more cascode connected MOS devices may further each have gate electrodes connected to a fixed potential so as to minimize the harmonic content. A control signal may further be applied to each gate electrode to turn off a leakage current path between source and drain electrodes. Harmonics may further be controlled by limiting a conductance between gate electrodes and fixed potentials using an active or passive device.
