Patent CA-2740665-A1 (CA)
Inventor: MCBRIDE DARVIL BENJAMIN
IPC: F23D14/84
Filed: 2011-05-20
Abstract: An acoustically variable burner system is provided, having a burner wherein the flow of gas thereto, and consequently the flame pattern resulting from the ignition of the gas, is variable by transmission of acoustic waves therethrough via an acoustically-based control system. The preferred burner design produces a realistic, wood-burning type flame pattern.  An acoustic controller, such as an APPLE® iPod®, MP3 player, computer, etc., may be utilized to drive/control electroacoustic transducers positioned adjacent the burner, the sound waves of which are produced thereby varying the flow rate of gas to the burner gas ports, thereby varying the flame height in direct correspondence with the audio signal. Further, the flame color may be altered by introduction of flame color variant compositions exposed to the flame via a flame color variation device removably positioned adjacent the burner. The system is preferably controlled via a specialized computer program running on the acoustic controller, which enables choice of flame patterns, duration, audible audio to accompany the flame display, etc.

Abstract: Methods, systems, and computer programs for issuing an implicit certificate are disclosed. In some implementations, a certificate authority of an elliptic curve cryptography (ECC) system performs one or more operations for issuing the implicit certificate. A  certificate request associated with a requester is received, and the certificate request includes a first element R U in a group. In response to receiving the request, a second element P U in the group is generated based on the first element R U. An implicit certificate Cert U is generated based on the second element P U. Whether the public key Q U of the requester corresponds to a trivial public key, such as an identity element of the group, can be determined. For example, the certificate authority can compute the public key Q U of the requester based on the first element P U, the implicit certificate Cert U, and a public key Q CA of the certificate authority.
