Abstract: Productivity and efficiency may be improved by eliminating or reducing interruptions by providing indications of availability for individuals where are based on a current activity in which the individual is employed. Current activity may be set manually be the individual or automatically, for example by monitoring applications and/or electronic devices with which the individual interacts. Indicator may be positioned on or proximate desktops, doors or sent electronically to computers and communication devices. Relationships between availability and activities may be set by the individual and/or a system administrator. Electronic communication may be suppressed based on the current activity. Relationships between activities or availability and the type of electronic communication suppressed or originator of the communication may be set by the individual and/or system administrator.

Abstract: First and second parties may be authenticated. After generating a challenge to the first party, two responses are received via the first party based on the challenge and two different keys. Two responses are also generated, and compared against the received responses. If the respective responses are verified, a confirmation is generated.

Abstract: A method, system and scheme are presented that provide a means of establishing secure and reliable two-way authentication with online service providers (“Providers”) using a hardware device. The account holders (“Users”) use a unique hardware device (“Hardware Device”), which is plugged into the communication technology, such as computer, being used to access online accounts. The device is used for storing cryptographic algorithms and keys that are capable of performing hashing, encryption and decryption operations. The device is periodically refreshed with new keys, which cannot be read or duplicated by the User.

Abstract: An illumination system including at least one reflector subtending an angle with respect to a location on a surface of an article, and first and second light sources, the first and second light sources each providing a light output, the light outputs from both of the first and second light sources being directed to impinge on the location on the surface of an article within the angle, at least one of the light outputs being reflected by the reflector.

Abstract: A ready-to-image gravure sleeve is supplied with a resist layer applied over the copper. The sleeve is loaded on a mandrel in an imaging device and imaged directly using an imagewise controllable radiation source. In subsequent processing steps the resist is developed and subjected to a chemical etch to form the gravure image in the copper.
