摘要:
Waveguide filters utilizing the TM modes in an evanescent waveguide are provided. The Q of such filters surpasses any evanescent, dual and triple mode filters in propagating or evanescent waveguides. The waveguide filter in accordance with the present invention features a small size, as well as ease and simplicity in its manufacture when compared with conventional filters. Filters of exceptionally high Q and very low loss, when compared to conventional filters, can be obtained by employing TM modes in an evanescent waveguide. The TM mode evanescent filter has a higher Q than either the evanescent TE mode standard filter of a single mode propagating waveguide (TM or TE) or even the dual or triple mode filters in evanescent or propagating waveguides.

A circuit for monitoring future Universal Serial Bus (USB) activities is described. Specifically, the circuit may comprise a Direct Memory Access (DMA) engine schedule prefetcher. The DMA engine schedule prefetcher accesses linked list schedule structures in main memory. The structures are checked for future frames where the linked list has USB activity scheduled. A periodic DMA engine subsequently accesses main memory only during frames where USB traffic is scheduled.

A system determines whether to grants access to a network server by a user. Initially, a user attempts to gain access to a network server, such as a web server. Prior to granting access to the network server, the network server authenticates the user by sending an authentication request to an authentication server. The authentication server determines whether the user was already authenticated by the authentication server. If the user was already authenticated by the authentication server, then the network server is notified that the user is authenticated. The network server then grants the user access to the network server. If the user was not already authenticated by the authentication server, then login information is retrieved from the user and compared to authentication information maintained by the authentication server. If the retrieved login information matches the authentication information, then the network server is notified that the user is authenticated. The retrieved login information and the authentication information is concealed from the network server. If the user is authenticated, then a user profile is communicated to the network server along with the notification that the user is authenticated. If the user is successfully authenticated, then a cookie is provided to an Internet browser operated by the user. The cookie contains information regarding user authentication, the user's profile, and a list of network servers previously visited by the user.

摘要:
Remote sensing of the temperature of a greybody or blackbody radiator is effected by passing its radiation (24) through a modulated infrared filter spectrometer. The infrared filter comprises, in sequence, a band pass filter (20), a first polariser (21) which polarises the radiation, an electro-optical element (22) which splits the polarised radiation into two orthogonally polarised components, and a second polariser (23). A lens (28) images the radiation leaving the second polariser onto a detector (27). The electrical signal from the detector (27) is input to a numerical analyser. The electro-optical element (22), typically comprising a birefringent crystal assembly (25) and a birefringent trim plate (26), is configured so that the net optical delay of the orthogonally polarised components passed through it is such that the recombined components are at or near a peak or trough in their interferogram. A sinusoidally varying voltage is applied to the electro-optical element to modulate the net delay of the components passed through the electro-optical element. The numerical analyser is programmed to compute the harmonic amplitude ratio (the ratio of signal amplitudes at the fundamental and second harmonic of the frequency of the modulating voltage) of the signal that it receives from the detector (27). The harmonic amplitude ratio is a function of the temperature of the radiator, which can be estimated by reference to a calibration look-up table.
