Abstract:
An electrical connector assembly is presented herein. The electrical connector includes a pair of connector blocks each defining a groove in an end surface that is configured to have an electrical conductor of an electrical cable partially disposed within it, e.g. a carbon nanotube conductor. The electrical connector also includes a housing configured to receive connector blocks, align the groove of one connector block with the groove of the other connector block, and hold the connector blocks together such that the electrical conductors within the grooves are in direct physical and electrical contact with the one another and are compressed. An electrical cable assembly incorporating such as connector and an method of manufacturing a cable assembly using such a connector is also presented.
Abstract:
A data transmission cable assembly includes an elongate first conductor, an elongate second conductor, and a sheath at least partially axially surrounding the first and second conductors. The sheath contains a plurality of electrically conductive particles interspersed within a matrix formed of an electrically insulative polymeric material. The conductive particles may be formed of a metallic material or and inherently conductive polymer material. The plurality conductive particles may be filaments that form a plurality of electrically interconnected networks. Each network is electrically isolated from every other network. Each network contains less than 125 filaments and/or has a length less than 13 millimeters. The bulk conductivity of the sheath is substantially equal to the conductivity of the electrically insulative polymeric material. The data transmission cable assembly does not include a terminal that is configured to connect the sheath to an electrical ground.
Abstract:
A safety system and a method configured to determine whether a passenger compartment of a vehicle is occupied whether the temperature of the passenger compartment is outside an acceptable temperature range, and to take a safety countermeasure if needed. An occupant is detected by sounds received by an audio transducer within the passenger compartment connected to an infotainment system. The temperature is detected by a temperature sensor connected to the heating, ventilation and air condition system of the vehicle. Example safety countermeasures include activating the horn, transmitting a wireless signal indicating that an unattended occupant is in the vehicle to a remote wireless receiver, and/or at least partially opening a vehicle window. A pair of high frequency speakers connected to the infotainment system may be used to transmit and receive ultrasonic signals so that an occupant may be detected using ultrasonic motion detection techniques.
Abstract:
A Universal Serial Bus (USB) cable assembly is configured to interconnect a USB device, such as a smartphone or digital music player, disposed within a motor vehicle with a USB hub disposed within the motor vehicle, such as in the vehicle's infotainment system. The USB cable assembly includes a first connector configured to interface with the USB hub, a second connector configured to interface with the USB device, and a plurality of wire cables interconnecting the first connector and the second connector. The USB cable assembly further includes a signal conditioning circuit in communication with the first connector, the second connector and the plurality of wire cables. The signal conditioning circuit is disposed intermediate the first connector and the second connector.
Abstract:
A method to construct a tape wrapped unshielded twisted pair (UTP) cable is provided. The method includes the step of twisting a first wire and a second wire together to form a twisted pair. The method further includes the step of wrapping tape around the twisted pair with an effective amount of tension on the tape such that a separation distance between the first wire and second wire does not substantially vary along the length of the twisted pair.
