摘要:
An apparatus includes: a first apparatus port receiving a first signal having a first frequency; a second apparatus port outputting the first signal having the first frequency; a first passive device connected between the first and second apparatus ports; a second passive device connected between the first and second apparatus ports; a plurality of phase shifters each providing a corresponding phase shift, wherein at least one of the phase shifters provides its phase shift in a first signal path between the first and second apparatus ports through the first passive device, and wherein at least another phase shifter provides its phase shift in a second signal path between the first and second apparatus ports through the second passive device. The phase shifts are selected to cancel an upper or lower intermodulation product between the first signal and a second signal having a second frequency received at the second apparatus port.

摘要:
A single cavity acoustic resonator comprises: a first electrode; a second electrode; a third electrode disposed between the first electrode and the second electrode. The single cavity acoustic resonator also comprises: a first piezoelectric layer disposed between the third electrode and the first electrode, and comprising a first C-axis having an orientation; and a second piezoelectric layer disposed between the third electrode and the second electrode, and comprising a second C-axis having an orientation parallel to the first C-axis. Application of a time varying electrical signal at a drive frequency to either the third electrode or to the first and second electrodes results in a resonance of the single cavity acoustic resonator at twice a fundamental resonant frequency and a cancellation of substantially all even-order mixing products in the single cavity resonator. An electrical filter and a duplexer are also described.

摘要:
A method and apparatus is disclosed for the customization of electronic equipment of which portable audio players, portable disc players, portable digital games and laptop computers are representative. The electronic equipment may be fitted with a substantially transparent faceplate that may cover removable inserts. These inserts may be customizable to provide unique decorative appearances to the electronic equipment upon which they may be fitted. Decorative designs may either be preprinted on the inserts or a user may produce a customized design.
摘要:
The invention proposes several improvements related to the management of secure elements, like UICCs embedding Sim applications, these secure elements being installed, fixedly or not, in terminals, like for example mobile phones. In some cases, the terminals are constituted by machines that communicate with other machines for M2M (Machine to Machine) applications.
摘要:
A status monitoring and reporting mechanism which distinguishes more significant events and prominently displays events pertaining to nodes, interconnections, and other network entities which may present problems, and to suppresses benign messages which may not require immediate attention, provides an “at a glance” view of overall system health. By processing and displaying aggregate status events from a plurality of agent components to highlight the most severe and critical events from among a large volume of general status events allows an operator to quickly diagnose potential problems before detrimental results occur, and helps maintain a general efficient system health by isolating less efficient areas to allow for timely remedial action prior to failure. Various agents disseminated in a storage area network determine and report status events back to a central server. The server receives, aggregates, and processes the status events to display a status array indicative of overall system health.
摘要:
A tetrakis(hydroxyphenyl)chlorin, bacteriochlorin or isobacteriochlorin, derivatised at one or more of the hydroxy groups by addition reaction with a diisocyanate, diisothiocyanate or isocyanate-isothiocyanate at one isocyanate or isothiocyanate group thereof, the other isocyanate or isothiocyanate group being itself derivatised by addition reaction with the hydroxy group of an w-alkylated or acylated poly(alkylene oxide) or to a hydroxy group of a link residue itself carrying a residue of such poly(alkylene oxide).
摘要:
A method and circuit matches a device to n filters, wherein each filter is a SAW filter, BAW filter, or FBAR filter. The method and system: (a) provide an inductor or transmission line connected between a common terminal and ground; (b) provide a plurality of capacitance values (C1m, C2m, . . . , Cnm) each corresponding to one of the n filters; and (c) for each of the n filters, directly connect a first terminal of the filter to either: (1) the common terminal, or (2) a first terminal of a corresponding capacitor having the correspondence capacitance value calculated in step (b), where a second terminal of the corresponding capacitor is directly connected to the common terminal.
