Title: Down conversion mixer
Inventor: SOKOLER IZYDOR
IPC: H03D9/00
Filed: 1997-05-09
Abstract: A down conversion mixer comprises first and second mixers 1.1, 1.2 in two parallel paths provided with the received signal and a respective one of two oscillator signals in anti-phase relationship. By filtering and combining the output signals from the mixers in the two paths, the disturbing second order terms from the mixers may be substantially eliminated. In a modification (fig.3 not shown), the input signal and the oscillator signal phase shifted by 90 and 270 degrees respectively are applied to additional mixers in third and fourth paths, the outputs of the mixers being combined to derive a signal in phase quadrature with the combined output signal of the first and second channels. A further modification (fig.4 not shown) applies balanced input and oscillator signals to mixers of the balanced type. The received input signal may be a phase and amplitude modulated signal.

Title: An electronic television programme guide
Inventor: ROBARTS JAMES O
IPC: H04N5/445
Filed: 1998-03-17
Abstract: An electronic programme guide (EPG) database is interrogated to produce a list of programmes that may be of interest to a viewer. Queries may be composed by users or may be developed automatically by inspection of viewing habits or viewer profiles. Viewer profiles may be produced by interrogation of the viewer. User queries may be stored hierarchically and queries relating to different viewers may be merged. Queries may be allowed to run continually to uncover programmes of interest as they arise in the EPG. Queries may restrict selection of certain categories. A 10-key alphanumeric keypad may be used to enter query data. The EPG interprets the data from each key to mean any of the numbers or letters associated therewith and identifies all possible programmes and channels and networks. As the viewer continues to add letters or numbers, the list narrows dynamically until only a few choices remain. The EPG data may be transmitted with the TV signals and may contain links to Web pages.

Title: Optimising device driver debug tracing
Inventor: COBBETT MICHAEL
IPC: G06F11/36
Filed: 1999-03-24
Abstract: In a method for executing, in a computer system (5, Figure 1) a device driver 10 which is used by applications running on the system, first 12 and second 11, versions of the device driver code are provided. The first version is optimised, and the second version contains debug code for providing trace information, whereby upon discovering a problem with the device driver, it is possible to selectively switch to the debug version of the code without any of the applications already using the device driver being aware of the switch. Having gathered the necessary trace data, it is then possible to transparently switch back to the optimised version. Switching between the first and second versions of the software component occurs in response to a system call, which sets a boolean flag of which the value determines which version of the software component is executed. Conventionally, device drivers form part of the operating system within a computer and so are difficult to remove and re-load without taking the whole system down and re-booting. This method, however, affords continuous service to any application already using the device driver and does not require a time-wasting reboot which may, in any event, remove the error condition.

Title: Determining program availability in a client-server network
Inventor: CIRALDO ROBERT
IPC: H04L29/00
Filed: 1999-12-29
Abstract: An apparatus and method for determining a program neighborhood of a client node in a client-server network are described. The program neighborhood of the client node includes application programs hosted by application servers on the network. A user of a client node can learn of these application programs. The user is not required to know where to find such applications or to manually establish links to such applications. To make the client node aware of its program neighborhood, a host server collects application-related information corresponding to application programs hosted by the servers in the network. The application-related information can include the application name, the server location of the application, minimum capabilities required of client nodes for executing the application, and those users who are authorized to use that application. User credentials are received from the client system. The user credentials are used to filter the application-related information. Information representing those application programs that are available to the client node is transmitted from the host server to the client system for displays, e.g. a graphical icon for each available application program.
