摘要:
A method of verifying the accuracy or authenticity of alphanumeric magnetic data on a document, wherein the configuration of a pictorial or graphic magnetic reference image in the document is made visible by bringing movable particulate magnetic material into proximity therewith such that the particulate magnetic material takes up a distribution corresponding to the magnetic field of the reference image; and the magnetic image configuration thus revealed is compared with the reference image to identify any significant disconformity suggesting past exposure of the document to a magnetic field capable of altering said magnetic data.

A magnetically-activatable sheet product is provided comprising a pair of laminated outer sheets between which is a magnetic layer comprising magnetically-activatable particles in a binder matrix, the outer sheets having sufficient opacity to mask the appearance of the magnetic layer, at least one of the outer sheets being provided on its outward facing surface with a coating which comprises either microcapsules containing a solution of at least one chromogenic material, or dispersed droplets containing at least one chromogenic material in a pressure-rupturable matrix, or a colour developer composition, or both microcapsules containing at least one chromogenic material and also a colour developer.
摘要:
A method for forming a stent and for also forming channels in the outer surface of selected regions of the stent structure. The method includes impinging a laser beam generated by a diode pumped Q-switched pulsed Nd/YAG laser operating at the third harmonic on an outer surface of a stent and controllably machining channels in the outer surface of the stent. The depth of the channels may be controlled by adjusting the power and pulse rate of the laser, and also by adjusting the rate at which the stent moves relative to the laser beam.

Methods for streaming web content data via a computer-readable medium. The web content data comprises one or more media samples. The media samples are encoded in a streaming media format as a web component stream. The web component stream is combined with other component streams comprising additional data other than web content data into a presentation stream. The presentation stream is transmitted via a media server to a client. Rendering commands, which are included in one or more rendering samples encoded in the web component stream along with the media samples, coordinate synchronization between the media samples and the additional data when the client renders the presentation stream.

The invention provides a process for the production of a compound of formula (I): wherein P1 and P2, which may be the same or different, are amino protecting groups, which comprises protection of a compound of formula (II) in solution phase continuous operation mode. This confers advantages over batch mode operation. The process is usually conducted in reaction equipment adapted for use in continuous processing mode, for example comprising one or more static mixers or a plug flow reactor. Preferably, the plug flow reactor comprises a jacketed tubular reactor fitted inside with internal mixing elements which continually split and remix the reaction streams promoting mass and heat transfer, whereby a uniform plug flow profile with turbulent fluid flow is achieved. The invention also provides a process for production of the antibacterial compound gemifloxacin or a pharmaceutically acceptable salt and/or hydrate thereof, comprising converting a compound of formula (I). The invention also provides a process for the production of a compound of formula (VIIIa).

The present disclosure provides systems and methods of the play of skill-based games of squares that maintains player engagement, and in contrast to existing sports fan games, provide opportunities for less avid sports fans to participate enjoyably. In accordance with aspects and embodiments, weighted point values are assigned to squares based on the desirability of the squares. In certain cases, the desirability of squares may be determined by a computerized system having a central hub and processor in communication with players via the internet.
摘要:
Apparatus and method for volumetric removal of cerebrospinal fluid (CSF) from the brain of patients suffering from hydrocephalus. The apparatus comprises a drainage conduit, which interconnects the cerebral ventricle system to a body cavity and an open and close pinch flow restrictor external to the drainage conduit to control flow. The flow restrictor has a controller that is remotely programmable. Also, the method provides for drainage of the CSF through the conduit by opening and closing the pinch flow restrictor for programmed durations. The actual opening and closing of the flow restrictor to actuate the drainage is determined by patient response to excessive or inadequate CSF diversion.
