Abstract:

Systems, methods, and apparatuses are presented for resolving any interference, noise, and/or collisions caused by two or more ingestible event markers (IEMs) transmitting simultaneously or concurrently. Methods include techniques from the perspective of the IEM for randomly varying signal transmission characteristics in order to avoid collisions with other concurrently transmitting IEMs. Methods also include techniques from the perspective of a receiver for receiving multiple transmission signals from multiple IEMs and for resolving any interference or signal collisions.

G02B 6/122

Abstract:

An optical assembly comprising: (a) a substrate having a first planar surface; (b) an optical component connected to the substrate and having a second planar surface parallel to the first surface and at least one first optical axis; (c) a plurality of optical fiber stubs having a certain diameter and being disposed at least partially between the substrate and the optical component; (d) at least one of the substrate or the optical component having one or more grooves on the first or second surfaces, respectively, such that each groove is configured to receive one of the plurality of fiber stubs such that each of the fiber stubs protrudes a first distance from the first or second surface to space the first surface the first distance from the second surface; and (e) a least one optical conduit having a second optical axis, the optical conduit being disposed on the first or second surface such that the second optical axis is optically aligned with the first optical axis.
