A method for enumerating platelets within a blood sample is provided. The method includes the steps of: 1) depositing the sample into an analysis chamber adapted to quiescently hold the sample for analysis, the chamber defined by a first panel and a second panel, both of which panels are transparent; 2) admixing a colorant with the sample, which colorant is operative to cause the platelets to fluoresce upon exposure to one or more predetermined first wavelengths of light; 3) illuminating at least a portion of the sample containing the platelets at the first wavelengths; 4) imaging the sample, including producing image signals indicative of fluorescent emissions from the platelets, which fluorescent emissions have an intensity; 5) identifying the platelets by their fluorescent emissions, using the image signals; 6) determining an average fluorescent emission intensity value for the individual platelets identified within the sample; 7) identifying clumps of platelets within the sample using one or more of their fluorescent emissions, area, shape, and granularity; and 8) enumerating platelets within each platelet clump using the average fluorescent emission intensity value determined for the individual platelets within the sample.

A portable grill includes: a cooking grate; a collapsible body surrounding the sides and bottom of the cooking grate and collapsible mesh basket when the grill is configured for cooking; a collapsible frame supporting the position of the body, cooking grate, and the mesh basket when the grill is configured for cooking; and a removable collapsible lid adapted to cooperate with the body to completely surround the cooking grate and mesh basket when the grill is configured for cooking, wherein the collapsible body and collapsible lid are formed primarily from a flexible high temperature resistant material.

The invention provides methods and systems for ruggedizing a nucleic acid analyzing apparatus. The ruggedized apparatus can be used reliably and effectively in uncontrolled environments, such as, for example at a crime scene to collect and analyze forensic data, as well as in semi-controlled environments, such as, for example at a point of care location.

A lens assembly particularly suited to use with high resolution digital cameras and other portable electronic devices. The lens includes a positive powered front group having one or two elements and a second, aberration correcting, rear group having in order from the front a bi-concave element, a meniscus element and a bi-concave element. The aperture stop plane is just in front of the front group. A combined operator and shutter device is positioned at the aperture stop plane. All of the lens elements are made of glass and have spherical surfaces.An objective lens for use in a digital camera or cell phone having a camera body, the lens having a sensor such as a CCD providing an active surface that serves as a focal plane, a digital image corresponding to a varying light image falling on the focal plane, a lens assembly for forming the varying light image, the lens assembly comprising a positive doublet having a first and a second element or a singlet, at the object end of the lens assembly followed by a lens element group spaced from the positive doublet or alternatively, a positive singlet and having three elements, in order from the object end, a bi-concave element, a meniscus element and a bi-convex element, and an aperture stop located at a predetermined distance in front of the positive doublet or positive singlet lens element at the object end of the lens assembly.<?insert-end id="INS-S-00001" ?>

A portable frequency synthesizer is provided with fine tuning over a broad bandwidth using a Fractional N type Delta Sum Phase Locked Loop circuit that enables elimination of boundary value spurs. In the system, frequencies where spurs occur are calculated to define a region of fractional N values that cannot be used with a first time base. To avoid the boundary spurs, a second time base reference is selected that can generate boundary spurs that do not overlap with the first time base. Circuitry is provided to select the appropriate time base and the fractional N values to generate desired output frequencies throughout the synthesizer range while avoiding the boundary spurs.

An air cleaning apparatus that includes a housing, a fan, an ultraviolet lamp, and a cylindrical filter. The housing has a separation plate that defines an air inlet region and an air outlet region inside the housing. The separation plate has a vent. An air inlet is formed through an outer surface of the air inlet region. An air outlet is formed through an outer surface of the air outlet region. A holder is located in the longitudinal direction of the housing. A fan is mounted in the air inlet region proximate to the vent of the separation plate. An ultraviolet lamp is mounted inside the holder. A cylindrical filter has a rotating part at one end thereof. The holder is arranged inside the cylindrical filter, and the rotating part is rotatably engaged with the opening.

The invention provides a large scale scene 3D modeling method and device based on a depth camera. The steps of getting current frame depth map information and pose information, resolving the depth map to get a current frame 3D point cloud, solving a movement amount of the current frame relative to a key frame, performing a movement amount threshold determination, performing the key frame 3D point cloud coordinate transformation, and finally establishing a scene 3D model. The invention also relates to a large scale scene 3D modeling device based on the depth camera. The key frame is used to perform 3D model construction, and modeling time and storage time consumption is low; the 3D point cloud is combined with an octree grid map, the requirement of a modeling process for the storage space is very low, and is very flexible, and multi-resolution random rapid switching is achieved. The large scale scene 3D modeling device is advantageous in that, one depth camera is combined with other sensors, providing economy and practicality; use flexibility and portability are provided, and the device can be placed onto various carriers, such as a vehicle-mounted, airborne, and hand-held device, so that the large scale scene 3D modeling device has a wider application field.

An external accessory for a portable fan including a base having an air inlet located in a side wall of the base, and an air outlet detachably connectable to the base, the accessory including a high energy particle arrester filter and connectors for detachably connecting the accessory to the fan so that the filter is located upstream from the air inlet of the fan.

A method of producing hard disk drives of reduced size including using a one or more MEMS spindle motors, and one or more magnetic heads. Each spindle motor includes a rotor and a stator. The rotor carries a film of magnetic film, and a head is arranged to communicate data with the magnetic film. The rotors are formed by MEMS technology. Rotor elements are formed within a substrate 4, and the substrate is subsequently cut to simulate the rotor elements, and turn them into rotors.
