Abstract: An adjustable tree stand has a housing in which a wheel rotates. The housing is strapped or otherwise secured to a tree in the usual way. The wheel has a first extension that protrudes from the housing and has a female receiver. A frame has a second extension with a downwardly directed male pin. The second extension sits atop the first extension with the pin received within the receiver to thereby connect the frame to the housing, Rotation of the wheel rotates the frame. A locking mechanism prevents the wheel from rotating when not desired. A threaded bolt passes through the frame and engages the housing in order to pivot the housing with respect to the frame. Appropriate platforms are attached to the frame.

Abstract: Described are devices, methods and non-transitory computer readable media for implementing an enhanced multi-factor authentication system. The system uses three user identifiers, and after a first user identifier is verified, the system receives a second user identifier from the user. As the second user identifier is being received, the system automatically detects a third user identifier and verifies simultaneously the second and third user identifiers. The second and third user identifiers are correlated with each other, and the correlation of these two identifiers (e.g., in addition to the identifiers themselves) is also verified.

Abstract: A light source is configured to emit a narrow peak at a discrete spectral band, especially at a primary color wavelength. The light source can have a plurality of narrow peaks to simulate the effect of a broadband light source. A subject is provided with a pigment, such as certain rare earth lanthanides, with a strong absorption peak at a corresponding narrow spectral band. The pigment has a nominal color when illuminated by a true broadband light (e.g., sunlight) that does not have a narrow peak at the discrete spectral band, and has a different color when illuminated by the light source that has a narrow peak. This color shift can be used for security authentication, information and decorative applications.

Abstract: Described are systems for combining multiple latent characteristics within a pigment such that with certain specialized knowledge and tools the specific pigment can be uniquely authenticated. The system takes advantage of the rapid proliferation of artificial light sources that are characterized by combinations of narrow band light sources that combine to simulate natural, or broadband light sources. With knowledge of the ambient lighting spectral emissions and the ability to illuminate the subject with an alternative light source with different spectral emissions, it is possible to determine the presence of the latent characteristics within the pigment. In some embodiments of the system, a smartphone including a CMOS or CCD sensor and a LED light source, could be combined with software to authenticate all of the latent characteristics. These characteristics can be combined with each other in different proportions to mass customize unique solutions for each customer or product line.

Abstract: An adjustable tree stand frame has a housing attached to a tree with a spindle rotatably disposed within the housing. One or more spring loaded pins are removably receivable within openings on an outer periphery of the spindle such that when so received within an opening, spindle rotation is prevented. A frame is pivotally attached to the spindle and uses a threaded shaft and a receiver to pivot the frame back and forth with respect to the spindle.

Abstract: A light source is configured to emit narrow peaks at discrete spectral bands, especially primary color wavelengths, added to simulate the effect of a broadband light source. A subject is provided with a pigment, examples being certain rare earth lanthanides, with a strong absorption peak at a corresponding narrow spectral band. The pigment has a nominal hue under true broadband light. When illuminated by the narrow band source, the absorption peak eliminates the contribution of one of the primary colors, producing a distinct shift in hue of the pigmented subject. The change in hue cannot be anticipated from the appearance of illuminated subjects that lack the pigment, which remain normal. The narrow absorption peak is not noticeable under unmatched light sources or true broadband light sources, e.g., sunlight. The hue shift effect is useful for security authentication, informational and decorative applications.

Abstract: A latent or “invisible ink” security marking formulation is provided using a phosphor with distinct emissions characteristics including visible emission due to excitation at a particular invisible wavelength. An insoluble inorganic phosphor with this or a similarly distinct emission characteristic is milled to a small particle size, preferably less than one micron particle diameter, and is combined with a carrier at very low pigment concentration, for example one percent by weight of the ink formulation. Preferably the pigment is cropped to resin particles in a binder. This ink formulation is diluted by a volatile solvent and applied using a conventional inkjet printer of the type used to mark codes on packages and labels. To test for security purposes the printing is irradiated and a response according to the predetermined characteristic is noted (or not noted) to detect security information.
