Abstract: Systems and methods for associating single cell imaging data with RNA transcriptomics. Single cells are isolated into microwells with a microbead having oligonucleotides conjugated on its surface. Each oligonucleotide includes a cell identifying optical barcode that is unique to that bead and binding sequence for RNA capture after cell lysis. The system is configured for loading single cells into the microarray and for flowing cell lysis buffers and other reagents into the microarray for performing RNA library sample preparation. The system is also configured for lowing optical hybridization probes that are complementary to the cell identifying optical barcodes and optically labeled onto the microwell array and for obtaining images of the microwells in response to the probes. The system and unique cell identifying optical barcodes and complementary optical hybridization probes facilitate a link between phenotypic imaging of cells resident on the microwell array with single cell whole transcriptome sequencing.

Abstract: A wireless receiver receives location pilots embedded in received symbols and uses the location pilots to detect the first path for every base station the network has designated for the receiver to use in time of arrival estimation. The receiver preferably applies matching pursuit strategies to offer a robust and reliable identification of a channel impulse response's first path. The receiver may also receive and use estimation pilots as a supplement to the location pilot information in determining time of arrival. The receiver can use metrics characteristic of the channel to improve the robustness and reliability of the identification of a CIR's first path. With the first path identified, the receiver measures the time of arrival for signals from that path and the receiver determines the observed time difference of arrival (OTDOA) to respond to network requests for OTDOA and position determination measurements.

Abstract: A sprinkler includes a compartment that surrounds its riser portion in an offset or asymmetrical configuration. More specifically, the distance of the compartments walls from those of the riser vary (i.e., increase or decrease) at different locations surrounding the riser. Put another way, the riser is closer to one side of the compartment than other sides of the compartment. This non-concentric configuration allows larger components to fit inside the compartment than would otherwise fit if the riser was symmetrically surrounded by the compartment.
