Granted: 2006-03-21
Abstract: An anti-decoupling arrangement for an electrical connector (as well as an electrical connector incorporating such an anti-decoupling arrangement) is made up of just three operative components: a spiral lock clutch , at least one spring ring, and ratchet teeth or serrations formed on an inside surface of the coupling nut. The ratchet teeth are in the form of serrations formed into the inside diameter of a recessed area of the coupling nut in which all of the components reside, and each spring ring is a self-supporting ring that has spring cantilevers with engaging tines of a given number located around its outer circumference, the engaging tines engaging the serrations in a radial direction. The engaging tines thus provide a torque/ratchet mechanism when they glide over the radial cuts of the tooth ring in the uncoupling direction, and stay engaged which forces the spiral lock clutch to expand and slide smoothly over the plug shell with minimal torque in the coupling direction.

Title: A method and system for providing copy-protection on a storage medium and storage medium for use in such a system
Inventor: STARING ANTONIUS A M
IPC: G06F1/00
Filed: 2000-03-14
Granted: 2008-07-29
Abstract: In a method for providing copy-protection services on a storage medium (for instance a solid state memory module), the data are arranged in sectors to which a field (S4T) is associated, where said field contains a random value Ri which is changed randomly when writing data to said sector. By encrypting the data stored on the medium using a key which depends critically on said random numbers, bit-by-bit copies (apart from said random numbers, which can not be deterministically changed by an application) to a second storage medium or recopies from some intermediate storage medium, can not be decrypted because the values of said random numbers will have changed, thus preventing unauthorized duplication and replay attacks.

Abstract: A telephone sterilization apparatus and method having ultraviolet sterilization of the mouthpiece and earpiece of a telephone handset. The invention has an ultraviolet source within the earpiece and mouthpiece cradl es of a telephone handset cradle. The telephone handset engages a seal around t he earpiece and mouthpiece which blocks UV illumination from a user and seals i n ozone gas that is produced by UV source below 200nm. The UV source illuminat ed the earpiece and mouthpiece of a telephone handset when the handset is in telephone handset cradle. When in the telephone handset cradle, the handset engages a switch, which signals a timer/power circuit, which provides a time d application of power to the UV source(s). The duty cycle of the UV source is timed for substantially complete sterilization of the telephone handset. Minute amounts of ozone gas surround the earpiece and mouthpiece of the telephone handset providing more complete sterilization.

Abstract: An improved burr for sharpening the grinding surface of a pulpstone includes a novel tooth configuration for better wear of the burr and enhanced grinding properties of the pulpstone. The profile configuration of the burr teeth has a truncated tip portion in the form of a rounded tip portion, a flat tip portion, or an obtusely angled tip portion to avoid a sharply pointed tip. The tip portion connects opposite sides of the tooth, with the sides forming either a symmetrical or an asymmetrical tooth profile using linear, convex involute, and concave involute side configurations. The present invention comprises a further improvement to a pulpstone sharpening burr, wherein the lead angle of the bun teeth changes periodically over the axial length of the burr to provide the pulpstone with a wave-like groove pattern.
