Abstract: A combustion air proving (CAP) system for a burner assembly having a burner for providing heated air to a location, a controller, and a back plate, where outside air is fed to the burner via a conduit. The CAP system is connected to an inlet of the system. An outlet of the system is connected to the burner via the back plate. A damper within the system is translatable between open and closed positions for allowing and blocking air flow, respectively. A sensor measures an air flow parameter of air flow to the burner. The sensor communicates with the controller, which shuts down the burner if the parameter measured by the sensor meets a predetermined threshold value. An assembly installer may test for proper sensor and controller functions by translating the damper to the closed position and blocking outside air flow.

Abstract: A computer-implemented method including receiving a request to facilitate a transfer of funds from a sender account of a sender at a sender financial institution to a recipient account of a recipient at a recipient financial institution. The request can include a public identifier for the recipient but not include an account number of the recipient account at the recipient financial institution. The method also can include determining, using an information directory, a private token for the recipient account based on the public identifier. The method additionally can include transmitting the private token of the recipient account to enable the transfer of the funds from the sender account to the recipient account. Other embodiments are disclosed.

Abstract: A method including receiving a funds transfer request initiated by a sender to facilitate a transfer of funds to a recipient. The funds can be transferred from a sender account of the sender at a sender financial institution to a recipient account of the recipient at a recipient financial institution. The funds transfer request can include a public token for the recipient but not including an account number of the recipient account at the recipient financial institution. The public token for the recipient can be confirmed as useable to contact the recipient based on one or more responses by the recipient to one or more authentication request messages provided to the recipient using the public token. The method also can include determining a private token for the recipient account using an information directory based on the public token. The private token can be embedded with information that identifies the recipient financial institution.

Abstract: An NQR scanner for detecting the presence of a substance containing quadrupole nuclei within an object. A pulse generating means (1) generates pulse sequences that are used to irradiate the object in a pulsed magnetic field at a requisite NQR frequency for the substance to be detected. A high power RF transmit amplifier (2) amplifies the signal to produce sufficient magnetic field strength to irradiate a scan volume within which the object is disposed for detection purposes and cause an NQR transition to a detectable level within the substance if present within the object.
