Abstract: Machine logic (for example, software) for protecting sensitive and confidential user data and sending the protected user data to an authorized third party for predictive analytics purposes. The machine logic rules perform linear transformation operations on the sensitive and confidential user data in order to obscure the underlying data before it is sent to an authorized third party for performing predictive analysis of the underlying data. After performing predictive analysis on the obscured data by the authorized third party, the owner of the sensitive and confidential data takes a consequential action (that is, the owner of the data makes a business-related decision) based on the prediction.

Abstract: An optical communications module is provided that has WDM capabilities for increased bandwidth and that is suitable for use with single mode optical fiber or multimode optical fiber. The module can be configured to have both WDM and BiDi functionality to further increase bandwidth and can have a single- or multi-channel configuration. The module has an integrally-formed body having an optical port and portions of an optical coupling system that are integrally formed in the body. The optical port is adapted to mate with an end of an optical fiber cable that holds one or more ends of one or more optical fibers, depending on whether the module is a single-channel or multi-channel module. The optical coupling system couples light between an end or ends of one or more optical fibers and one or more optoelectronic devices in a way that reduces back reflection and mode partition noise.

Abstract: An optics system is provided that comprises a glass-based diffractive optical element (DOE) for coupling an optical signal passing out of an optical waveguide into a photodetector. The glass-based DOE improves optical link performance by performing one or more of shortening a response time of a photodetector, preventing an overloading condition of the photodetector from occurring and managing back reflection of light from the photodetector. The glass-based DOE is relatively inexpensively to manufacture and is reliable over a wide range of temperatures.

Abstract: A mechanism is provided for predicting and reducing product return. For a historical regular product purchase associated with a current product purchase by a customer, a distribution of a number of product purchases and a distribution of a number of product returns is generated. A determination is made of a probability of return of the current product as a function of the number of product purchases, the number of product returns, a distance, and a browsing time. Responsive to the identified probability of return being greater than a predetermined threshold, the identified probability of return is used to reduce the probability of return of the product through one or more interactions with the product.

Abstract: In a bidirectional optical communications module, an optics system is provided having a lens block that uses a single surface for reflecting light into or reflecting light passing out of the end of the optical fiber and a single surface for reflecting light toward a monitor photodetector. No other surfaces in the lens block are used to turn the light path. A filter block of the optics system that is adjacent to the lens block performs wavelength multiplexing and demultiplexing. The filter block reflects light at either its lower or upper surface back toward the lens block. In some embodiments, a portion of light passes through the upper surface of the filter block to provide some attenuation of light being transmitted so that the light is not coupled back into the light source. Because the upper surface of the filter block is the topmost surface of the optics system, the optics system can be very compact while also limiting the number of surfaces that turn the light path.
