  • Publication number: 20240065590
    Abstract: An apparatus for procuring bodily fluid samples with reduced contamination includes a housing having a sequestration chamber, an inlet, and an outlet. A flow controller defines a portion of the sequestration chamber and can transition—in response to a suction force exerted by a fluid collection device fluidically coupled to the outlet—from a first state in which the sequestration chamber has a first volume to a second state in which the sequestration chamber has a second volume greater than the first volume, to draw an initial volume of bodily fluid into the sequestration chamber. An actuator is coupled to the housing and is in fluid communication with the inlet and the sequestration chamber in a first configuration, and is transitioned to a second configuration to sequester the sequestration chamber from the inlet, and allow a subsequent volume of bodily fluid to flow from the inlet to the outlet.

  • Patent number: 7313159
    Abstract: An improved grating-outcoupled surface-emitting semiconductor laser architecture is provided. A second-order grating is placed between two distributed Bragg reflector gratings. The period of the second order grating is positively or negatively detuned from the distributed Bragg reflector selected optical wavelength at which the laser operates. Detuning of the second-order grating towards shorter or longer wavelengths allows kink-free, linear LI curves light output versus forward current) for grating-outcoupled surface-emitting lasers. Due to the detuning of the outcoupler grating, the outcoupled radiation emits two beams that deviate slightly from the normal axis. A design point may then be chosen where the power outcoupled by symmetric and antisymmetric modes cross and where the outcoupled power is independent of the phase variation.

  • Publication number: 20050140503
    Abstract: A tactile generator comprises an eccentric mass that imparts a vibration as it rotates about a rotational axis. The mass is radially movable with respect to the rotational axis such that the distance between the mass and the axis is variable. Varying the distance of the mass from the axis varies the amount of vibration generated when the mass is rotated. The amount of vibration may be controlled responsive to a detected level of ambient noise.

  • Patent number: 6888874
    Abstract: A laser diode system is provided. The laser comprises first and second reflective gratings at each end of the laser. The laser further comprises an outcoupling grating between the first and second reflective gratings, wherein the outcoupling grating couples light out of the laser. The reflectors and outcoupling grating each have a unique wide-band reflective spectrum. A first laser cavity exists between the first and second reflective gratings. A second laser cavity exists between the first reflective grating and the outcoupling grating. A third laser cavity exists between the second reflective grating and the outcoupling grating, and a fourth laser cavity exists with in the outcoupling region. The overlap of reflective spectra determine the lasing wavelengths that reach resonance within each cavity. Wavelengths resonant in one cavity are suppressed in the others unless a wavelength is resonant in all cavities. This matching of mode intensities causes the outcoupled beam to be confined to a single wavelength.

  • Patent number: 6810067
    Abstract: A laser source is provided by the present invention, comprising a laser diode and has an active region with asymmetric distributed Bragg reflectors (DBRs) at either end to reflect light within the cavity, and an outcoupling grating in the center of the device, which couples light out of the cavity. One DBR is long and shallow, with a narrow-band reflective spectrum. The other DBR is short and deep, with a wide-band reflective spectrum. The lasing wavelength is determined by the reflective spectrum overlap of the two DBRs. Since the shallow DBR is highly reflective to only one Fabry Perot wavelength, and the deep DBR is highly reflective to a wide band of Fabry-Perot wavelengths, it is the reflective spectrum of the shallow DBR that determines the lasing wavelength.

  • Patent number: 5042675
    Abstract: This invention pertains to a novel pressure relief device for a container which is under pressure or becomes pressurized. In one aspect, the invention is directed to a pressure relief vent for a battery which, due to adverse chemical reaction, may become pressurized to a hazardous level. A pressure release vent for a container comprising: (a) a container having a wall; (b) an indentation formed in said wall, the indentation being interrupted by a flat-topped fold which extends across the indentation and reduces the depth of the indentation at a specific location; and (c) a score formed in said fold, the score providing a point of weakness whereby excessive pressure buildup in the container ruptures the container wall at the score location, thereby permitting pressurized gases to escape from the container.
