Title: Protection circuit for current-driven loudspeakers
Inventor: MERILAEINEN ESA
IPC: H04R3/00
Filed: 2010-09-23
Abstract: The power protection of a current-driven speaker 1 can be accomplished dynamically and without breaking the operation by connecting, through a rectification bridge 2a-d, a power transistor 5 in parallel with the driver to be protected 1; the control voltage of said power transistor 5 being indicative of the voice coil warming in said driver 1. The voltage to be monitored may yet be filtered before rectification (16, fig 3), so that the voltage would better represent the voltage dropped in the voice coil resistance. Other embodiments are disclosed (figs 4 and 5). By driving an electro-dynamic loudspeaker with a current signal instead of the conventional voltage signal, one can achieve, in addition to superior sound quality, also better-performing protection against driver overloading.

Title: Shifted pilot sequences repeated across VDSL sub-carriers for crosstalk cancelling vector training
Inventor: CLAUSEN AXEL
IPC: H04B3/32
Filed: 2010-10-26
Abstract: A training sequence, for instance a Walsh-Hadamard sequenc, F1to Fmis applied to each of the tones y of a VDSL system such that the sequences are offset from their neighbours by one symbol. The tones are transmitted on a subscriber loop and used to estimate cross talk, in particular far end cross talk (FEXT), between subscriber loops. These estima tes can then train a vectoring system for pre/post cancellation of cross talk. The estimation may involve obtaining errors in transmitted pilot sequences, which form the basis for calculating intermediate vectors and crosstalk couplings.

Title: Anticipation of server responses and roll back in distributed application
Inventor: LANNI LEONARDO
IPC: G06F15/173
Filed: 2013-02-13
Abstract: On client-side of a distributed application, a current submission of a user request is transmitted to a server-side of the distributed application so as to receive a current server response. A default value is set for the current server response if the current server response is not received from the server-side within a time-limit with respect to the cut-rent submission of the user request. A log of operations performed against the distributed application is started from the assignment of the default value to the current server response. On receiving an actual value that is different from the default the logged operations are rolled back and the current server response reset to the actual value. The default value may be set according to prior responses, using a frequency distribution, or using the highest frequency, perhaps within a group, such as a particular time period. An error condition may be entered if the server side response is not received within a further period, these delays may be set based on prior experience of return speed. An indication of the current server response may be displayed in a web page. The current submission may disable the caching mechanism of the browser.
Patent GB-2513198-A (GB)
Title: Security systems and methods
Inventor: VALLEE NEIL ANTHONY LE
IPC: H04L9/08
Filed: 2013-04-19
Abstract: Authorising a payment using a card e.g. debit, credit and store cards, between a user having a wireless device 2 e.g. a mobile phone, and a remote registration location B e.g. a registration database, comprises using four codes to generate a unique authorisation code. The first code is associated with the device 2, e.g. produced from an IMEI or serial number and a licence code. On registration this is transmitted to the registration location B with returns a registration code to be stored on the device. The device 2 may generate a test message using the two codes to confirm registration. A third code is read from the card 26 by a device 25 integral with or connected to the wireless device 2 e.g. using a magnetic strip or chip reader or using near field detection and a fourth code is entered by the user, e.g. a PIN or biometric data. The wireless device transmits the third and fourth codes using a predetermined card registration call number, these being checked at the registration location which may check the card has not previously been registered, and returns card registration information to the wireless device including encryption instructions and a call number to use for that particular card. To process a payment the wireless device uses in part a standard encryption key and in part an encryption key constructed from the four codes to encrypt an authorisation code for sending to the remote location via the predetermined number.

Abstract: The invention describes a nuclear reactor having a core comprising an array of closed bottom hollow tubes which contain fissile isotopes in a molten form. The core is at least partially immersed in a tank of coolant (the blanket) which may also contain a heat exchange mechanism. In such an arrangement, a convective flow of blanket fluid moves up between the tubes in the array of the core and down through said heat exchange structure, thereby eliminating the need for pumps. The liquid fuel preferably comprises fissile isotopes dissolved in a molten salt, but a liquid metal may also be used. The coolant is preferably also a molten salt, but may also contain a fertile isotope such as thorium or uranium.

Title: Method of identifying a fault
Inventor: BRISCOE STUART
IPC: F01P11/16
Filed: 2013-11-22
Abstract: A method of identifying the condition of a temperature responsive valve, eg mechanical thermostat 107, which controls the flow of coolant in an engine cooling system 101 having a radiator 103 comprises (i) measuring t1, the temperature of coolant fluid as it exits the engine; (ii) measuring t2, the temperature of coolant fluid as it exits the radiator; and (iii) diagnosing the condition of the temperature responsive valve, eg whether it stuck, dependent upon the measured values of t1 and t2. The thermostat 107 may be identified as stuck open if t1 and t2 meet a first criterion or as stuck closed if they meet a second criterion. The method may also involve calculating a radiator cooling factor tr = (t2 t3)/(t1 t3) where t3 is ambient temperature. A fault in the thermostat may be reported if the fault occurs more than a predetermined number of times.

Title: Method and apparatus for improved QAM constellations
Inventor: STOTT JONATHAN
IPC: H04L27/34
Filed: 2014-03-10
Abstract: A method of determining non-uniform constellation positions of a two-dimensional Quadrature Amplitude Modulation scheme (NU-QAM) is provided. The scheme has words of n coded bits mapped to each constellation point, for a signal to be transmitted over a channel in a system using a forward error corrector (FEC). The method selects a signal to noise ratio (SNR) appropriate for the channel and the forward error corrector and then constrains the positions of at least some constellation points to have n-fold symmetry, where n is an integer > 4, e.g. n = 8 or 16. The method then determines the positions of the constellation points that maximise a measure of channel capacity at the selected SNR. The constraint to n-fold symmetry simplifies calculations whilst ensuring appropriate constellations positions are selected.
