Abstract: Coated substrates and methods may comprise a multi-unit carbodiimide. The multi-unit carbodiimide may also be combined with a siloxane. The multi-unit carbodiimide and/or the siloxane may be used in a surface coating applied to a substrate, and an overcoat may be applied to the surface coating. The surface coating may chemically interact with the overcoat and/or the substrate to improve corrosion resistance and other properties of the coated substrate.

Abstract: An electrical connector that supports electrical connections of different types is described. The electrical connector includes a terminal support unit that includes an aperture array and is configured to support a terminal module seated in the terminal support unit. The terminal module supports at least one terminal that requires strict relative positioning, such as a high-speed data terminal. The electrical connector includes a terminal lock that interfaces with the terminal support unit to stabilize and lock a terminal array thought the aperture array, and to lock the terminal module in a mating position.

Abstract: An electrical connector assembly includes a connector body defining a terminal cavity in which an electrical terminal is received which has a flexible primary terminal lock arm configured to secure the terminal within the cavity and which has a tab extending from a free end of the primary terminal lock arm. The assembly further includes an independent secondary lock (ISL) defining a window therein, attached to the connector body, and movable from a pre-staged position to a staged position. The tab of the primary terminal lock arm is received within the window when the primary terminal lock arm is in an unflexed condition when the ISL is in the staged position. The tab and window cooperate to inhibit flexing of the primary terminal lock arm when the ISL is in the staged position. Alternatively, the primary terminal lock arm may define the window and the ISL may define the tab.

Abstract: Techniques are provided for the optimal matching of teachers to students using machine learning models and analysis engines (MLMAEs). In an embodiment, historical and biographical teacher and student data is collected through a data ingestion layer. As the data is ingested, a process is spawned that automatically builds MLMAEs using a plurality of algorithms. The MLMAEs are automatically tested for accuracy, and the MLMAE with the highest level of accuracy is promoted as the winner. Students enter information through a user interface to request optimal teachers for a subject area, and this information is run against the winning MLMAE which returns a list of optimal teachers. Also provided are techniques for teachers to enter their availability, techniques for MLMAE creators to seamlessly test prospective new MLMAEs, and techniques for teachers to understand why they are not matches for specific segments of students and to receive associated professional development resources.

Abstract: An electrical connector includes a first-housing, a second-housing, and a connector-position-assurance (CPA) device. The first-housing has two parallel actuation-ribs extending from an outer-surface of the first-housing. The actuation-ribs are aligned parallel to a longitudinal mating-axis of the electrical connector. The second-housing is configured to mate with the first-housing and includes two opposing lugs projecting from a top-surface of the second-housing. The CPA device is slideably mounted to the second-housing and is moveable from a pre-stage-position to a latched-position. The CPA device includes two parallel latching-arms that engage the lugs. The latching-arms are in a relaxed-state when in the pre-stage-position. The actuation-ribs disengage the latching-arms from the lugs when the first-housing is mated with the second-housing. This enables the CPA device to be moved from the pre-stage-position to the latched-position.

Abstract: An electrical connector includes a first-housing, a second-housing, a slideable-skirt, and a terminal-lock. The second-housing is configured to mate with the first-housing along a longitudinal-mating-axis. The second-housing defines a slot in a top-side of the second-housing extending along a lateral-axis orthogonal to the longitudinal-mating-axis. The slideable-skirt is mounted to the second-housing and is moveable from a pre-stage position to a seated-position along the longitudinal-mating-axis. The slideable-skirt overlays a portion of a perimeter of the second-housing and defines cam-slots on a first-side and a second-side of the slideable-skirt. The terminal-lock is disposed within the slot and is moveable from a terminal insertion position to a locking position. The terminal-lock includes cam-posts extending from a first-end and a second-end of the terminal-lock disposed within the cam-slots.

Abstract: Disclosed is a mobile device to provide enhanced security based upon contextual sensor inputs. The mobile device may include: a biometric sensor; a contextual sensor; and a processor. The processor may be configured to: determine an authentication score based upon a biometric input received from the biometric sensor; modulate the authentication score based upon a contextual sensor input from the contextual sensor related to an event; and determine if the modulated authentication score falls below a predetermined threshold. If the authentication score falls below the predetermined threshold, the processor may command that a secondary authentication be performed.

Abstract: One feature pertains to biometric authentication of a user between devices. In one aspect, an ad hoc personal wireless network may include a primary device and one or more secondary devices using grouping policies such proximity policies and other permissions. The primary device shares a biometric authentication value of a user with the one or more secondary devices. Each secondary device may then perform additional authentication of the same user using a relatively low reliability biometric sensor such as a digital camera for facial recognition, a microphone for voice recognition or an accelerometer for gesture recognition. The secondary authentication results may be combined with the biometric authentication score/level from the primary device to form a final authentication score/level of the secondary device, which is used to authenticate the user of the secondary device for one or more transactions such as consumer purchases, secure content access, or secure control.
