Abstract: A message is embedded within an entropy stream. The message is encrypted using a onetime pad (OTP) and thus looks like part of the entropy string since the OTP encrypted messages is, as long as the “pad” material and message content are known, itself random to the observer. The encrypted message contains information used to identify and/or point to relevant information in another part of the entropy stream. For example, the OTP-encrypted message may indicate the number of units of the message, and point to a position in another part of the stream where another message is located. The stream may be randomly and deterministically expanded.

The transparent aliphatic cross-linked polyurethane layer has a glass transition temperature in a range from 11 to 27 degrees Celsius and a Tan Delta peak value in a range from 0.5 to 2.5. The display film has a haze value of 2% or less.

Abstract: An ember and flame resistant resettable automatic soffit vent includes a tray with ventilation openings formed in its floor. A mesh screen resides on the floor of the tray spanning the ventilation openings. A flat slide resides atop the screen and also has ventilation openings that match those of the tray. The slide has an open position wherein its ventilation openings align with those of the tray to allow airflow through the vent and a closed position wherein its ventilation openings are misaligned with the ventilation openings of the tray to close off airflow through the vent. The vent can be manually moved between its open and closed positions and one or more tension springs and a thermal link assembly cooperate to move the slide to its closed position if the vent is exposed to a high temperature cause by a fire very near a home.

Abstract: Methods and systems are provided for providing assistive action to a driver of a vehicle to increase a following distance between the vehicle and a target lead vehicle. In one example, providing assistive action includes, operating the vehicle manually behind a target lead vehicle on a road, including estimating a following distance between the vehicle and the target lead vehicle, and responsive to the following distance being less than a first threshold following distance, providing an assistive action by adjusting a mapping from a driver demand to a wheel torque of the vehicle to increase a perceived resistance of the vehicle to the driver demand as the following distance decreases.

Abstract: Methods and systems are provided for an air system. In one example, a system includes a boost device configured to be driven by exhaust air from a plurality of cylinder in order to compress ambient air. The compressed ambient air is delivered to a tank configured to store compressed gases.

Abstract: A cable support device, cable tie and cable tidy are provided. The cable support device includes a retainer, for retaining the cable support device to an edge of a surface, such as a desk or table, and a cable support, coupled to the retainer, and configured to support one or more cables. The retainer comprises: a planar upper support member; and an opposing biasing member, configured to bias the surface towards the planar upper support member to thereby retain the retainer to the surface. The biasing member tapered along its length, such that it is more flexible at its end.

Abstract: An actuator is introduced that utilizes the forces that result from placing a current carrying coil in a magnetic field to rotate a connected object about at least one axis. In some embodiments, the introduced coil actuator includes a coil of conductor coupled to an arm or other type of structural element that extends radially from an axis of rotation. The introduced coil actuator can be utilized to provide motion control in a variety of different applications such as gimbal mechanisms. In some embodiments, the introduced coil actuator can be implemented in a gimbal mechanism for adjusting an orientation of a device such as a camera relative to a connected platform such as the body of an aerial vehicle.

Abstract: A hardcoat composition includes one or more multifunctional (meth)acrylate monomers, and a nanoparticle mixture dispersed within the one or more multifunctional (meth)acrylate monomers. The nanoparticle mixture includes a first population of semi-reactive nanoparticles having an average particle diameter in a range from 5 nm to 60 nm, and a second population of non-reactive nanoparticles having an average particle diameter in a range from 5 nm to 60 nm.

There are latch pin legs extending from the main body. The swing down panel is adapted to mount devices to the swing down panel. The swing down panel includes pivot ears extending from the swing down panel to attach to pivot ear retention legs and includes latch pin retention legs extending from the swing down panel to attach to latch pin legs.

Abstract: A streaming one time Pad cipher using a One Time Pad (OTP) provides secure data storage and retrieval. The data that is encrypted using the one time pad is stored in a repository that is separate from the generation and/or storage for the one time pad.

Abstract: Methods and systems are provided for user controlled engine revving. In one example, the engine may be revved to a peak speed according to a target revving sequence in response to a user-initiated command. A revving sound may be provided in response to an input device, without demanding manual depression of an accelerator pedal.

Abstract: A streaming one time Pad cipher using rotating ports for data encryption uses a One Time Pad (OTP) to establish multiple secure point-to-point connections. This can be used to implement a streaming OTP point-to-point firewall, virtual private network or other communications facility for communicating secure information across one or more insecure networks.

Abstract: Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, responsive to receiving a request for sanitization of a vehicle interior, activating an ultraviolet germicidal irradiation (UVGI) system and operating a heating, ventilation, and air-conditioning (HVAC) system to heat the vehicle interior above an upper threshold temperature for a threshold duration. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes while the UVGI system may supplement the heat sanitizing.

Abstract: Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, responsive to receiving a request for cleaning an interior of a vehicle, adjusting a position of a sun shade based on at least one of an ambient temperature outside of the vehicle and a sun load of the vehicle, and operating a heating, ventilation, and air-conditioning (HVAC) system to heat the interior above an upper threshold temperature for a first threshold duration. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes.

Abstract: Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, while receiving power from an external power source and responsive to receiving a request for cleaning an interior of a vehicle, operating an electric heater of a heating, ventilation, and air-conditioning (HVAC) system to heat the interior above an upper threshold temperature for a first threshold duration using the power received from the external power source. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes while vehicle battery power and fuel are conserved by using power supplied from the external power source.
