An orally administrable implement for expanding in a stomach of an animal, including a mammal, to fill a space in the stomach, is provided for weight control. The implement includes: a fluid-permeable expandable container having a first dimension and a second dimension; and a plurality of clusters comprising a swellable material contained within the container and capable of swelling when contacted with a fluid; whereby when the implement is ingested, the fluid in the stomach enters the container causing the clusters therein to swell and the container to expand from the first dimension to the second dimension.

A real-time digital cytometer on a chip system utilizing a custom near field CMOS active pixel intelligent sensor that is flip-chip attached to a fluidic microchannel etched in a thin glass substrate. The CMOS active pixel sensor, fabricated using a 0.18 micron process, is a mixed signal chip comprising a sixteen pixel linear adaptive spatial filter coupled to a digital serial interface. This near field hybrid digital sensor topology obviates the need for both high resolution analog to digital conversion as well as conventional microscopy for the realization of real time optical cytometry. The custom sensor based design approach affords efficient scaling into a tiled multi-channel sensing configuration. The complete system, supported by a handheld graphical user interface and control module, demonstrates a viable micro total analysis sub-system for sample preparation and analysis which can support a wide range of applications ranging from cytometry to cell growth kinetics and analysis and various forms of fluid and droplet metering on an integrated and compact microfluidic platform.

Designs and operational methods to increase the dynamic range of image sensors and APS devices in particular by achieving more than one integration times for each pixel thereof. An APS system with more than one column-parallel signal chains for readout are described for maintaining a high frame rate in readout. Each active pixel is sampled for multiple times during a single frame readout, thus resulting in multiple integration times. The operation methods can also be used to obtain multiple integration times for each pixel with an APS design having a single column-parallel signal chain for readout. Furthermore, analog-to-digital conversion of high speed and high resolution can be implemented.

An imaging system for identifying the location of the center of mass (“COM”) in an image. In one aspect, an imaging system includes a plurality of photosensitive elements arranged in a matrix. A center of mass circuit coupled to the photosensitive elements includes a resistive network and a normalization circuit including at least one bipolar transistor. The center of mass circuit identifies a center of mass location in the matrix and includes: a row circuit, where the row circuit identifies a center of mass row value in each row of the matrix and identifies a row intensity for each row; a horizontal circuit, where the horizontal circuit identifies a center of mass horizontal value; and a vertical circuit, where the vertical circuit identifies a center of mass vertical value. The horizontal and vertical center of mass values indicate the coordinates of the center of mass location for the image.

A wide dynamic range image sensor provides individual pixel reset to vary the integration time of individual pixels. The integration time of each pixel is controlled by column and row reset control signals which activate a logical reset transistor only when both signals coincide for a given pixel.
