Abstract: Systems and methods provide increased authentication security by verifying that a device is associated with a human user (as opposed to, for instance, malicious code). In some configurations, a request for authentication is received from a device that includes an identifier of the device (e.g., an IP address of the device). A determination is made that the identifier of the device was not previously associated with a human user. In response to determining that the identifier of the device was not previously associated with a human user, a verification process is initiated to determine that the device is associated with a human user.

Abstract: Systems and methods for weak authentication data reinforcement are described. In some embodiments, a request to authenticate a user is received. A user password is determined to be a weak password. The user is verified to be human by initiating a human verification process. In response to verifying that the user is human, an option is provided to replace the weak password with a strong password.

Abstract: Systems and methods for weak authentication data reinforcement are described. In some embodiments, authentication data is received in a request to authenticate a user. In response to detecting weak authentication data, the systems and methods determine whether the user was previously authenticated as a human user. An example embodiment may include initiating an authentication process based on determining that the user was previously authenticated as a human user.

Abstract: A method is described for forming hollow particles, or shells, of extremely small size. The shell material is heated to a molten temperature in the presence of a gas that is at least moderately soluble in the shell material, to form a solution of the molten shell material and the soluble gas. The solution is atomized to form a multiplicity of separate droplets that are cooled while in free fall. Cooling of a droplet from the outside traps the dissolved gas and forces it to form a gas bubble at the center of the droplet which now forms a gas-filled shell. The shell is reheated and then cooled in free fall, in an environment having a lower pressure than the gas pressure in the shell. This causes expansion of the shell, to form a shell having a small wall thickness compared to its diameter.

Abstract: Laser pyrometer techniques are utilized to accurately image a true temperature distribution on a given target without touching the target and without knowing the localized emissivity of the target. The pyrometer utilizes a very high definition laser beam and photodetector, both having a very narrow focus. The pyrometer is mounted in a mechanism designed to permit the pyrometer to be aimed and focused at precise localized points on the target surface. The pyrometer is swept over the surface area to be imaged, temperature measurements being taken at each point of focus.

Abstract: The improved, heterogeneous catalysts are in the form of gas-impervious, hollow, thin-walled spheres (10) suitably formed of a shell (12) of metal such as aluminum having a cavity (14) containing a gas at a pressure greater than atmospheric pressure. The wall material may be, itself, catalytic or the catalyst can be coated onto the sphere as a layer (16), suitably platinum or iron, which may be further coated with a layer (18) of activator or promoter. The density of the spheres (30) can be uniformly controlled to a preselected value within .+-.10 percent of the density of the fluid reactant such that the spheres either remain suspended or slowly fall or rise through the liquid reactant.
