Patent GB-2499615-A (GB)
Title: Waveform generation
Inventor: CHETTIMADA VINAYAK KARIAPPA
IPC: G06F1/02
Filed: 2012-02-22
Abstract: A predetermined waveform is generated using a lower frequency clock signal (16) and a higher frequency clock signal (18). The waveform transitions between first and second states (12,14) in synchrony with timing signals (18-1 to 18-Â­11) of the higher frequency clock signal (18). The higher frequency clock is operated if the waveform will transition between the first and second states (12, 14) before the next timing signal (16-2) of the lower frequency clock. The higher frequency clock is powered down if the waveform will not transition between the first and second states (12, 14) before the next timing signal (16-3) of the lower frequency clock. The predetermined waveform can thus be generated having higher resolution but with lower power consumption. A state-change count is set at the beginning of the first state (12) and reduced by one for each high clock timing signal. On the low clock timing signal a power-save count is implemented. At a synchronisation point (16-2) the counts are compared with the result determining if higher speed clock is powered down.

Title: Continuous score-coded pitch correction and harmony generation techniques for geographically distributed glee club
Inventor: COOK PERRY R
IPC: G10L25/90
Filed: 2011-04-12
Abstract: Despite many practical limitations imposed by mobile device platforms and application execution environments, vocal musical performances may be captured and continuously pitch-corrected for mixing and rendering with backing tracks in ways that create compelling user experiences. In some cases, the vocal performances of individual users are captured on mobile devices in the context of a karaoke-style presentation of lyrics in correspondence with audible renderings of a backing track. Such performances can be pitch-corrected in real-time at a portable computing device (such as a mobile phone, personal digital assistant, laptop computer, notebook computer, pad-type computer or netbook) in accord with pitch correction settings. In some cases, pitch correction settings include a scorecoded melody and/or harmonies supplied with, or for association with, the lyrics and backing tracks. Harmonies notes or chords may be coded as explicit targets or relative to the score coded melody or even actual pitches sounded by a vocalist.

Title: Speech synthesis by combining probability distributions from different linguistic levels
Inventor: LATORRE-MARTINEZ JAVIER
IPC: G10L13/08
Filed: 2012-11-30
Abstract: In a text-to-speech synthesiser which converts text input (15, fig. 1) to audio output (17), a multi-level probability model relating all potential speech vectors to a specific utterance is generated at a range of linguistic levels. Text is first converted into linguistic units of different level (eg. syllables on one level, words on another) each having a duration of several frames, and linguistic context (eg. phonetic, prosodic, semantic or syntactic information) associated with each unit. Each unit is then related to linear parameters of a speech signal contour according to probability distributions (fig. 3) in a model of speech vectors (eg. fundamental frequency F0, lsp, aperiodicity, S405 fig. 4), whose mean and variance are determined during the training of the system (figs. 6-9). The probability distributions of all the different levels are finally combined a la Bayes and Expectation Maximization algorithms to give a total Gaussian distribution for speech vector x having a mean x and a variance P.

Title: Parallel optical communications system with electromagnetic interference (EMI) containment
Inventor: MEADOWCROFT DAVID J K
IPC: G02B6/42
Filed: 2013-01-18
Abstract: Electromagnetic interference (EMI) is contained in a parallel optical communications system 1. A curved surface 10a is formed in a housing 2 near an opening 12 through which a stack 13 of ribbon cables passes. The stack 13 of ribbon cables is sandwiched in between the curved surface 10a and a spring 10b. The spring 10b exerts a force on the stack 13 of ribbon cables and presses the stack 13 against the curved surface 10a and forms a sharp bend in the stack 13 just before it passes through the opening 12. Because EMI radiation is restricted to propagation along the sharply bent pathway of the stack of ribbon cables, most or all of the EMI radiation travelling along that pathway is either attenuated or reflected before it reaches the opening.

Title: Disc drive with three sensors for rotational and linear vibration compensation
Inventor: HUANG FU-YING
IPC: G11B19/04
Filed: 2013-03-21
Abstract: A magnetic recording disk drive has three vibration sensors 201, 202 and 203 mounted to the disk drive base 16 to provide feed forward vibration compensation signals. First 201 and second 202 spaced-apart sensors have their primary sensitivity axes 201a and 202a aligned generally parallel to a radius from the disc rotational axis 13 to the head 24 positioned along an arcuate path 90 on the disc between the inside diameter position hID and outside diameter position hOD, for detecting rotational vibration about the disk rotational axis and linear vibration in the cross-track direction. A third vibration sensor 203 has its primary sensitivity axis 203a aligned generally orthogonal to the primary axes of the first and second vibration sensors for detecting primarily linear vibrations in the along-the-track or track circumferential direction. The disk drive servo control processor calculates, from the signals from the three sensors, a rotational vibration feed forward signal, a radial linear vibration feed forward signal, and a circumferential linear vibration feed forward signal which are summed with the actuator control signal to compensate for the vibrations.

Title: Water diverter valve
Inventor: ARIS ROBERT JOHN
IPC: F16K11/10
Filed: 2013-03-27
Abstract: A water diverter valve 1 comprises a body 3 having a bifurcated water inlet pipe 2, a primary, flow pipe 9 and outlet pipe 10. Within the body 3 there are two shuttle valves 4, 6 that slide to allow their ports either to align with the respective pipes or to seal the respective pipes. Shuttle valve 4 acts as a control shuttle valve driven by static or induced pressure against the action of spring 5. Shuttle valve 6 acts as a diverter shuttle valve against spring 7 driven by a heat sensing device 8. Water inlet pipe 2 is connected to primary flow pipe 9 via port 13 in control shuttle valve 4. Similarly water inlet pipe 2 is interconnected to both primary flow pipe 9 and outlet pipe 10 via port 14, passage 12, port 16 and port 17. Water flowing below the design temperature is diverted to outlet pipe 10 and thence to a conserved water capture system. Once the water reaches design temperature heat sensing device 8 redirects the water to the end user tap. A passage 11 permits pressure equalization on both faces of shuttle valve 6.
