Abstract: A prior art security seal is molded one piece thermoplastic having a flag for receiving indicia such as serial number and so on and a strap extending from the flag. A locking socket depends from the flag at the junction with the strap. One or more projections extend from the flag from a surface opposite to the socket. The flag is too small for certain implementations which require a flag for receiving large labels. A large flag capable of receiving such labels is attached to the seal via the seal flag and projection. The flag has a channel for receiving the seal flag in an axial direction parallel to the plane of the flags and an opening for receiving the one or more projections, the opening having a contour that matches that of the projection(s). Snap fit latches secure the seal at flanges thereof as the projection(s) is inserted in the opening in a direction normal to the plane of the flags. The seal flag is releasably held in two normal directions to the large flag.

Abstract: A card may include a photoconductive layer and an electrophoretic layer. The impedance of the photoconductive layer is lowered when struck by light from the light-emitting layer. Where the impedance of the photoconductive layer is lowered, the electrophoretic layer may be addressed by an applied electric field to update an image on the card. The image on a card may be updated by a system of updating an image on a card and a method of updating an image on a card that are presented.

Abstract: The invention provides a novel method for down-regulating the biological activity of osteoprotegerin ligand (OPGL, TRANCE) thereby rendering possible the treatment/amelioration of diseases characterized by excessive loss of bone mass, e.g. osteoporosis. Down-regulation is effected by inducing an immune response against OPGL in an individual in need thereof. Immune responses can be raised by classical immunization with immunogenic variants of OPGL or by nucleic acid immunization where the nucleic acids encode the OPGL variant. The invention also pertains to compositions, polypeptides and nucleic acids useful in the invention, as well as to vectors and transformed host cells useful in the preparation thereof.

Abstract: For reducing a peak value in single-carrier modulated or multi-carrier modulated digital transmitter signals, the peak value is first determined from a plurality of transmitter symbols contained in the digital signal. If a predetermined value is exceeded, a replacement symbol is generated which replaces a predetermined transmitter symbol. The replacement symbol is so chosen that it lowers the peak value and is convertible into the original transmitter symbol without error using a coding which was used to create the transmitter symbols.

Abstract: Systems and methods for ultrasound sensing a compound's concentration in aqueous solution are provided. As a result of the ultrasound sensing, an accurate real time measurement of the concentration of the compound of interest in aqueous solution is obtained. In various non-limiting embodiments, the invention provides ultrasound sensing of methanol's concentration in aqueous solution in connection with a fuel circulation process for a direct methanol fuel cell. Since the speed of sound in a water-methanol system increases significantly with methanol content, techniques for measuring characteristic sound velocities are used to give sufficient resolution for a fuel circulation process.
