Abstract: A method and system for authenticating a digital optical medium, such as a CD-ROM, determine whether the medium is an unauthorized copy, or the original. The original media is created, or altered, so as to contain anomalous locations from which the transfer of data is accomplished at different rates than a standard digital copy would exhibit. One implementation of the process involves timing analysis of the differences in data transfer rates, and does not necessarily require the retrying of data reads, nor does the process require the media to exhibit fatal errors, as in conventional approaches. The process can be employed in systems that control access to unauthorized copies, or may be used for other informative purposes. Theft, distribution, and piracy of digital content on optical media, such as computer software (also games, video, audio, e-book content), is often accomplished by copying it directly to another disc using commonly available copy tools and recordable optical media, or the replication of media to another mass manufactured disc. The present invention, which helps to irrefutably identify a unit of optical media as the original, and can correspondingly identify any copy made by any currently available means as such a copy, may prevent an unauthorized individual from making use of any unauthorized copies. This offers significant advantages to content creators who wish to protect their products.

Granted: 2010-10-12
Abstract: An orthodontic bracket or convertible buccal tube for use with arch wires has the usual mesial distal extending slot having one side open to receive the wire. The open side is closed by a shutter pivoting on a pivot pin, or coaxial pins, about a mesial distal axis, the shutter being latched in slot closed position to retain the arch wire by a latch having one latch member on the pivot pin/s and a cooperating member on an annular part of the shutter surrounding the pin/s. Preferably the latch members are a mesial distal extending cam shaped recess in the pivot pin/s and a projection protruding from the annular shutter part, or vice versa. The part of the annular shutter part carrying the latch member is made flexible by a mesial distal extending through slot dividing it to form a movable segment of about 200° to 270° of the total circumference; a tool can be inserted into the slot to assist in disengaging the latch. The shutter member can have parts thereof that with the shutter in slot closed position are an interference fit against the device body providing an additional retaining force against opening movement. Preferably the device includes an attitude controlling spring member consisting of a thin sheet metal spring within the body having a free end extending into the arch wire slot to engage an arch wire therein, or alternatively consisting of a flexible extension of the part of the shutter member that closes the slot.

Abstract: An electronic animal trap with a CPU-controlled, rearming, high voltage output circuit for trapping and exterminating pests. The high-voltage out put circuit is connected to a pair of killing plates which are activated with a high-voltage pulse train for a period of time constituting a killing cycle when a known impedance is sensed across the plates. If, upon conclusion of the killing cycle, the impedance remains across the plates, the circuit activates a visual indicator to alert a user that the trap contains a dead mouse. However, if the impedance increases to that of an open circuit, likely meaning the animal has escaped, the circuit automatically rearms itself and no visual indicator is initiated.

Abstract: La présente invention a trait à un système d'antenne réseau à commande de phase comportant une carte de circuit imprimé incorporé à lignes microrubans en réseau de distribution de guide d'ondes. La carte de circuit imprimé à lignes microrubans reçoit une énergie d'onde électromagnétique en provenance d'une plaque d'entrée d'un réseau de distribution de guide d'onde 1x4 et répartit l'énergie d'onde électromagnétique vers 524 éléments de rayonnement. La carte de circuit imprimé à microrubans permet un espacement extrêmement serré d'éléments de rayonnement d'antenne indépendants qui ne serait pas possible avec un guide d'onde à air rectangulaire. Le système d'antenne permet le fonctionnement à des fréquences d'onde millimétrique, et notamment à 44 GHz, et sans nécessiter une pluralité de tables de référence pour divers retards en phase et en amplitude, qui seraient autrement nécessaires avec une structure de répartition à guide d'onde à air. Le système d'antenne peut être utilisé à des fréquences d'onde millimétrique, et en connexion avec le protocole de communications MILSTAR, sans nécessiter la connaissance préalable de la fréquence de saut suivante utilisée par le protocole MILSTAR.
