Title: Cooling apparatus
Inventor: JONES TIMOTHY ROY TRELEAVEN
IPC: B67D1/08
Filed: 1996-08-08
Abstract: A cooling apparatus, which is suitable for use in a soft drinks machine or like liquid dispenser, and is compact and can cool the liquid fast enough to be acceptable in a demand-led arrangement and yet not cool it so much that it actually freezes, comprises a cooling system (11) that utilises a combination of a heat pump (17: typically a Peltier-effect device) coupled with a liquid/solid phase-change material (15) operating in the required temperature range (which will usually be from just above 0{C to around +5{C). A temperature-sensitive switching device, such as a thermistor (19) is thermally coupled to the liquid/solid phase-change material (15) and operatively linked to the heat pump (17) so as effectively to control the pump on or off as required. In one embodiment a series of copper pipes act to transfer heat between the heat pump (17) and the phase change material (15). In another embodiment, a heat exhanger containing liquid to be dispensed, contacts the outside of a thermally-conductive cone-shaped former.

Patent GB-2337676-A (GB)
Title: Modifying filter implementing HRTF for virtual sound
Inventor: SIBBALD ALASTAIR
IPC: H04S3/00
Filed: 1998-05-22
Abstract: A head-related transfer function (HRTF) is used to place a virtual sound source at a particular position in 3D space. The absence of modelled sound reflections from the virtual sound source, and the presence of unwanted real reflections from real sound sources, can impair the effectiveness of the positioning of the virtual sound source. By modifying a filter for implementing an HRTF, the spectral profile of the HRTF is. exaggerated by convolving the near-ear and/or far-ear transfer function with itself. This results in more effective placement of virtual sound images in 3D space, giving improved realism of 3D effects. This is of particular use in the virtualisation of multi-channel surround sound systems.

Patent GB-2333601-A (GB)
Title: Method and apparatus for measuring acoustic power flow within an ear canal
Inventor: JENG PATRICIA S
IPC: A61B5/12
Filed: 1997-08-12
Abstract: A system and method for accurately determining the power flow within a test subject's ear canal. A calibration device (300) is used in conjunction with a probe device (400) that measures the frequency response of a cavity. The probe (400), with earphone (440), is inserted into a patient's ear and a transducer (460, 470) emits a periodic signal into the ear canal. The transducer (460, 470) also measures the frequency response of the ear canal and relays the data back to a digital signal processor. The same probe setup (400) is then calibrated by measuring the frequency response of a plurality of cavities (340a, 340b, 340c, 340d) having known geometries. Mean cavity length is solved for based upon the known geometries of the plurality of cavities. Consideration is also given to spreading mass wave phenomena due to point source transducer emission. Cavity temperature for calibration purposes is maintained as close as possible to body temperature thereby negating a further source of error. Several measurements, including cavity impedance and pressure reflectance, are calculated from the frequency response data obtained. This data, in turn, yields valuable diagnostic information for determining ear pathologies in humans The method and apparatus of the present invention is quick, easy, and efficient thereby lending itself to clinical use.

Title: Manufacture of liquid crystal alignment layer having areas with different alignment properties
Inventor: TUFFIN RACHEL PATRICIA
IPC: G02F1/1337
Filed: 1999-06-01
Abstract: In the manufacture of a ferroelectric liquid crystal cell 20, the alignment layers 7 and 8 provided on the inside surfaces of the substrate structures 13 and 14 for imparting a preferred alignment to the molecules of the liquid crystal layer 10 in the vicinity of the layers 7 and 8 are formed by deposition of two different alignment solutions, such as LQT120 and JALS212 for example, on the substrate structures 13 and 14. A mixture of the alignment solutions was applied by spin coating and subsequently the solvent was evaporated by prebaking prior to a further baking step and a rubbing step to impart a preferred alignment direction. The resulting alignment layers 7, 8 have a speckled structure in which areas 30 are interspersed within areas 31. The different areas 30, 31 have different alignment properties which serve to control switching of molecules of the liquid crystal material between alignment states in response to an applied electric field. In this manner it is possible to effect control of the partial switching behaviour of the device and to control the analogue greyscale in a display device.
