Abstract: A base layer for use in hazardous environments, such as smoky environments, the base layer (1) comprising a composite fabric (100) comprising a breathable membrane layer (101) having a multiplicity of pores and a breathable fire-retardant fabric layer (102,103) having a multiplicity of openings, the breathable membrane layer laminated on at least one side to the breathable fire-retardant fabric layer with an adhesive (104,105).

Abstract: A system has a first non-transitory computer-readable medium storing a first program and a second non-transitory computer-readable medium storing a second program, the first program and second program including instructions that, when executed by one or more processors, execute a method of verifying a secure message tunnel during a communication session. The method includes: selecting a pseudo random byte string; breaking the pseudo random byte string into binary format; following the breaking the pseudo random byte string into binary format, transmitting a message between the first non-transitory computer-readable medium and the second non-transitory medium; following the transmitting the message, shifting a binary array associated with the pseudo random byte string and assigning a unique shift value to the message; determining the unique shift value has been reused; and responsive to the determining the unique shift value has been reused, breaking the session.

Abstract: A method of securely replacing a first data value with a second data value and related systems are disclosed. The method includes generating a first public key and a first private key, generating a cryptographic seed value, and passing the cryptographic seed value through an elliptic curve to generate a second public key and a second private key. The method further includes combining the first public key with the second private key using public key cryptography to create a shared encryption key and passing the shared encryption key through a symmetric algorithm to encrypt the cryptographic seed value.

Abstract: The present invention relates a control system and method for supplying droplets within a space for controlling humidity. The control system comprises a droplet generator and a control unit. The droplet generator comprises at least one outlet and is configured to supply droplets to the space. The control unit is configured to control ejection of the droplets from the droplet generator to control the humidity in the space.
