A conductor of a twisted-pair data cable comprises a primary profiled insulation layer formed over a conductive wire, and a second insulation layer formed over the primary profiled insulation layer. This design prevents nesting of the profiled insulation layers of adjacent conductors without the need to back-twist or forward-twist the conductors, thereby maintaining consistent center-to-center distance between the conductors of a twisted pair. Since the second insulation layer prevents nesting between the primary layers regardless of the widths of the troughs of the cross-sectional profile, this configuration also allows for a greater range of width ratios between the peaks and troughs of the cross-sectional profile, which can allow greater freedom in tuning the electrical characteristics of the twisted pair.

SINGLE PAIR ETHERNET CONNECTOR SYSTEM WITH INTEGRATED EXTERNAL NOISE ISOLATION
A cable connector is designed to suppress at least a portion of energy that radiates from the signal contacts within the connector itself, and also reduces the effects of electrical interference from either other pairs in nearby connectors or other electrical sources. This is accomplished by grounding the connector's two outermost electrical contacts, thereby providing a path to ground between the signal contacts within the connector itself and any outside elements, including other signal pairs within other nearby connectors. To further improve signal integrity, the spacing between the connector's contacts can be selected such that the impedance of the connector substantially matches that of the cable terminated by the connector, thereby reducing return loss.

INSULATION DISPLACEMENT CONTACT CAPABLE OF SECURELY TERMINATING A WIDE RANGE OF ELECTRICAL CONDUCTORS
An insulation displacement contact (IDC) is capable of securely terminating wires having a wide range of diameters. The IDC is also designed to withstand repeated terminations of wires having diameters at the large end of the supported size range while remaining capable of securely terminating wires having diameters at the small end of the range. To these ends, the IDC comprises two or more distinct flex regions. At least one of the flex regions has an associated mechanical stop that limits the degree of deformation that can be applied to that region as a wire is being terminated on the IDC. If the diameter of the wire being terminated on the IDC is large enough to deflect the first flex region to the end of its deflection range, the mechanical stop is engaged, causing further deflection to be transferred to the next flex region.

Method for securely transmitting lighting scenes over a computer network with cloud setup and authentication
Techniques for securely controlling multiple lighting devices simultaneously with a lighting control device are disclosed. Command messages may be transmitted from the lighting control device to multiple lighting devices over a computer network without routing through a remote cloud service. The messages may be encrypted and may include an incremented sequence number. Lighting devices that receive a command message may compare the incremented sequence number to a previously stored sequence number corresponding to the lighting control device. If the incremented sequence number is greater than the stored sequence number, then a lighting device may determine the message was transmitted by an authorized lighting control device and may implement any command instruction included therein. If the incremented sequence number is equal to or less than the stored sequence number, then the lighting device may determine the command message was transmitted by a malicious source and may ignore the command message.

An electrical contact suitable for use within data connectivity applications in which both power and data are conveyed over the same pair of conductors is configured with a staggered profile geometry that isolates the location of high-current disconnects while maintaining a surface that remains free of electrical arcing and erosion. The electrical contact is designed with two points of contact, and the staggered geometry ensures that only one of the two points of contact is exposed to electrical arcing when the connector is disconnected while under power, thereby protecting the other point of contact from arc-related surface damage.
Multi-pole and single-pole circuit breakers include a housing and a reset lockout mechanism disposed within the housing. The reset lockout mechanism disables electrical communication between line and load terminals of the circuit breaker if a predefined condition exists. Some circuit breakers include a single actuator, transition between ON and OFF states, and are capable of performing test functions. The test functions may involve testing AFCI and/or GFCI functions of the circuit breakers. The test functions may be performed when the circuit breaker transitions from an OFF state to an ON state. Some circuit breakers including a reset lockout mechanism may be powered only on its line side. Some circuit breakers provide an electrical indication when they are in the OFF state.
