Abstract: A photonic device for detecting rotation and a corresponding method for operation thereof are disclosed. The photonic device includes a readout structure coupled to a ring resonator at one or more coupling points. Light is split between a lower waveguide and an upper waveguide of the readout structure in a forward direction at a beam splitter. The light in the waveguides traveling in the forward direction is coupled into the ring resonator and subsequently back into the waveguides in a reverse direction. The light is spatially phase tilted and is combined at the beam splitter. The combined light is detected by a split detector.

Abstract: A continuous flow bypass manifold comprising a fixed portion and an attachment portion for removable connection with the fixed portion. The fixed portion, fixedly installed into a fluidic system, defines a flow path and comprises inlet and outlet ports, a bypass valve disposed in the flow path, a bypass outlet tube proximate the inlet port, and a bypass inlet tube proximate the outlet port. Two attachment tubes can be coupled to at least one flow-through series component and attached to the bypass outlet and inlet tubes to form an alternate flow path through the at least one flow-through, series component upon manipulation of the bypass valve to close the flow path through the fixed portion and divert the fluid to flow through the flow-through series component. This addition of a series component is accomplished without disassembling and/or reassembling the fluidic system or interrupting fluid flow.

Abstract: A high speed mailing system that utilizes a single postal security (PSD) device in conjunction with multiple printing modules is provided. The control unit with which the PSD is associated is coupled to each of the printing modules through a multiplexer capable of switching between each of the printing modules. During initialization of the system for each mail processing session, the control unit establishes a secure communication session with each printing module individually through the multiplexer. Thus, the control unit can generate and provide indicia that can be printed only on the specific printing module that is currently in use. The multiplexer can switch between printing modules during operation of the mailing system, thereby always keeping one printing module in use while allowing the printing module that is not currently being used to perform any necessary maintenance operations, without having to stop the processing of mail pieces.
