    Abstract: In a positioning system (100) for estimating the position of a mobile device (7), a processing system (9) receives external-range data, representative of a range between the mobile device and an external unit (2, 3, 4, 5), and acceleration data representative of acceleration of the mobile device due to its movement as it is carried by a person (6). The acceleration data is processed in a step-detection algorithm to determine step-distance data representative of a time series of step- data-based distances travelled by the mobile device, and step-distance data is processed to determine a step-data-based position estimate for the mobile device. A position estimate for the mobile device is determined by solving an optimisation problem comprising a first cost term based on distance to positions located at said range from the external unit, and a second cost term based on distance to the step- data-based position estimate or to positions located at a step-data-based distance from said step-data-based position estimate.

    Abstract: The invention provides a method for monitoring peripheral microcirculation in a vertebrate animal subject undergoing or recovering from surgery, wherein said method uses unfocused ultrasound pulses to determine a characteristic of blood flow within in the minor peripheral vasculature of the subject and said characteristic or the profile of said characteristic over time is indicative or predictive of a change in the peripheral microcirculation of the subject. The invention further provides a method for monitoring or predicting the onset of and/or progression of dysfunction of the microvasculature and/or a response to treatment thereof in a vertebrate animal subject, wherein said method uses unfocused ultrasound pulses to determine a characteristic of blood flow within in the minor peripheral vasculature of the subject and said characteristic or the profile of said characteristic over time is indicative or predictive of dysfunction of the microvasculature or response to treatment thereof or variation in said characteristic or a profile of said characteristic over time is indicative or predictive of dysfunction of the microvasculature or is indicative or predictive of a change in the dysfunction of the microvasculature or response to treatment thereof.

    Abstract: A radio communication apparatus(1) receives or generates a base address seed, and generates data-channel access addresses from the seed. Each access address corresponds to a respective data-channel identifier, and is generated by setting a bit at a common first bit position to the value of a bit at a first common predetermined bit position in the base address seed or in the respective data-channel identifier; by setting a bit at a common second bit position to the bitwise complement of this value; and by setting one or more remaining bit positions in dependence on values atone or more bit positions in the base address seed and one or more bit positions in the respective data-channel identifier that are not thefirst common predetermined bit position. The apparatus (1) can send or receive a radio data packet comprising an access address from the generated set.

    Abstract: A system(1)for determining three-dimensional spatial information about an object(2), such as a fish, comprises a projector(4), a camera(5, 6), and a processing subsystem (3). The projector(4)emits structured light towards the object(2). The light has a periodic intensity pattern, having a first spatial frequency in a first direction. The camera(5, 6)captures images of the object(2)over time. The processing subsystem (3)determines aspeed of the object(2), relative to the projector(4), and instructs the projector(4)to control the emitted structured light in dependence on the speed, such that the intensity pattern is shifted, relative to the object(2), between successive images, by a spatial-phase step that is independent of the speed of the object(2). The processing subsystem(3)then usesimages from at least two time frames to calculate spatial phase values for points on the object(2), and uses these spatial phase values to determine three-dimensional spatial information about the object (2).

    Abstract: A resettable microcontroller (1) comprising a processor (7), a memory (11, 13), a memory bus, and memory protection logic (9). The microcontroller (1) is arranged to clear a set of memory- protection configuration registers (26) whenever the microcontroller (1) is reset. The memory protection logic (9) is arranged to access the set of memory-protection configuration registers (26) and is configured to monitor memory access requests on the bus; detect when a memory access request attempts to access a memory address in a protectable region of the memory (11, 13); determine whether the memory access request satisfies an access criterion for the protectable region, the access criterion depending on data stored in the set of memory- protection configuration registers (26); block the memory access request when the access criterion is not satisfied; and prevent writing to any memory-protection configuration register (26) unless the memory-protection configuration register (26) is in a cleared state.

    Abstract: A radio receiver (5) is arranged to receive radio signals. The radio receiver (5) includes a tuner (4), which outputs an electronic signal representing radio waves received by the radio receiver; a correlator (18), which cross-correlates a predetermined signal pattern with the electronic signal, and outputs a correlation signal; and a clear channel assessment module (22). The clear channel assessment module determines when the number of peaks in the correlation signal, over a fixed time window, exceeds a threshold count value, and outputs a busy signal in response to determining that the number of peaks exceeds the threshold count value.

    Abstract: A digital radio receiver (7) is arranged to receive and process data frames, each data frame comprising (i) a plurality of identical synchronization sequences; (ii) identification data different from the synchronization sequences; and (iii) convolution-encoded message data. An initial-synchronization section of the receiver (7) uses the plurality of synchronization sequences in a received data frame to perform a frequency- synchronization or symbol-timing-synchronization operation. A frame-synchronization section determines frame-synchronization information by correlating at least a part of the received identification data against reference identification data stored in a memory. A convolution-decoding section uses the frame-synchronization information to decode the message data.
