Title: Error concealment in scalable video transmissions
Inventor: HARE JONATHON STEPHEN
IPC: H04N19/89
Filed: 2001-11-07
Abstract: A method for improving a quality of MPEG4, or similar, scalable video enhancement layers transmitted over an error-prone network. The method includes the steps of inserting one or more re-synchronisation markers (660, 760, 860) into one or more enhancement layers of a scalable video sequence. When one or more errors (630, 730, 830) is detected in said one or more enhancement layers of said scalable video sequence, data is concealed (640, 740, 840) in the video sequence from a video bit position at which said one or more errors is detected, to a video bit position of a subsequent error free re-synchronisation marker. In this manner, a reduction in the amount of error-free data that has to be discarded can be achieved. This, in turn, reduces the amount of visual degradation in the video transmission.

Title: Organic light emitting device
Inventor: GILMOUR SANDRA
IPC: G09F9/30
Filed: 2003-06-20
Abstract: A light-emitting device comprises a substrate (13), a light-emissive layer (15) disposed over the substrate, and a grating (17) for aligning the light-emissive layer (15). The grating (17) aligns molecules of the emissive layer (15), so that the device emits polarised. The grating also reduces waveguiding effects in the device, so increasing the useful light output of the device. The invention may be applied to an organic light-emitting device (OLED). The grating (17) may align substantially the entire area of the light-emissive layer (15) in a first direction. In this case, substantially the entire emissive area of the device will emit layer of a single polarisation. Alternatively, the grating (17) may align a first region of the light-emissive layer in a first direction and may align a second region of the light-emissive layer in a second direction different from the first direction.

Title: Determining blood pressure using pressure pulse duty cycle
Inventor: KULIK ROBERT STANLEY
IPC: A61B5/022
Filed: 2003-07-31
Abstract: Blood pressure parameters are determined by obtaining oscillometric blood pressure pulse data of a subject using a occlusion cuff and then analysing the shape of pressure pulse data. The pressure pulse period of a cardiac cycle of a subject is determined, the duration of a pressure pulse detected within a pulse period is identified and the duty cycle of the pressure pulse is calculated with respect to the pressure pulse period (duty cycle =pulse duration / pulse period). Blood pressure parameters are then determined from the duty cycle (e.g. by comparison with numerical thresholds). Blood pressure is hence determined using a temporal (rather than amplitude) based calculation.
