A method of detecting one or more diseased blood cells in a blood sample includes introducing a blood sample into at least one inlet of a microfluidic device comprising one or more linear channels wherein each channel has a length and a cross-section of a height and a width defining an aspect ratio adapted to isolate diseased blood cells along at least one portion of the cross-section of the channel based on reduced deformability of diseased blood cells as compared to non-diseased blood cells, wherein diseased blood cells flow along a first portion of the channel to a first outlet and non-diseased blood cells flow along a second portion of the channel to a second outlet. The one or more channels can be adapted to isolate cells along portions of the cross-section of the channel based on cell size. In some embodiments, the one or more channels can be spiral channels.

The present invention relates to an improved system and method for providing a personal channel of linear programming to a subscriber in a content delivery network (CDN). The system and method of creates a linear channel for a subscriber in a predetermined arrangement of program scheduling from file information corresponding to media content data in predetermined arrangement of program scheduling to optimize the playback and the user experience. The predetermined arrangement of program scheduling is determined from one or more user characteristics based on service requests from the user or subscriber's interaction with a resource manager, a scheduler service and/or catalog service. According to methods of the present invention the personal channel for channel creation may be based on content provider, who will structure channels for a particular area, subscriber or other grouping of any available program scheduling. The personal channel of linear programming may be configured to use media content that has been predetermined for a particular personalized channel, whereby such a personalized channel may also change content from program to program, so that a version of the channel would be similar but unique to the viewer, such that a linear channel may be the basis service but individual programs will be swapped out from file information for the desired media content e.g. VOD, DVR, NDVR or other file based sources from said CDN.

A communications system (10) which utilizes an M-ary QAM signal constellation suitable for non-linear applications. The communications system includes a modulator (18) for utilizing the M-ary constellation to implement the modulation. The M-ary constellation is a circular constellation which provides a simplified amplitude predistortion by utilizing the subject M-ary constellations, enabling more efficient communications can then be achieved through a peak-power-limited non-linear channel (16). Such non-linear channels (16) are more power efficient at creating RF energy from DC energy.

A self-closing drawer slide has a housing with a linear channel extending therein at an inner end of an outer longitudinal section. A catch is slidably mounted within the channel and has pivot pins 36 extending out either side thereof (only one side is shown) into corresponding slots in the sides of the channel. The catch is symmetrical about a longitudinal centre line of the housing and rocks rearward to unlock and engage a latch on an inner longitudinal section and forward to lock and release the latch. The catch is biased to slide to an inner end of the channel when the catch is unlocked and there are no external forces on the slide.
