Abstract: A non-systematic convolutional decoder of a convolutionally encoded multi-level data stream includes a shift register and two or more paths of exclusive-OR (XOR) gates, arranged to reconstruct an original input information stream, each path having a quantiser arranged to quantise the signal to two levels, and a set of XOR gates arranged to match an encoding path in an associated convolutional encoder, and a selector arranged to feed an output from each path to a single input of the shift register. If the paths have differing values at their output, the selector may choose the value from the path based upon a function of the multi-level signals associated with each path, such as the path with the largest absolute signal level. The decoder provides a simple means for decoding signals while allowing the signal to also or instead be decoded using e.g. a Viterbi decoder if higher performance is required.

Abstract: A system for compensating for phase noise, with particular application in lidar, includes a compensation interferometer that receives a signal from a source, and splits it into a first and second path, with a path length difference ?? between them. Typically the path length is significantly less than that of the return distance to a target. The output of the compensation interferometer, which consists of phase noise generated in time ?? is vectorially summed during a time similar to a signal flight time to a target, and the result used to reduce phase noise present on measurements of a target. It further includes means for selecting ?? such that competing noise elements are reduced or optimised.

Abstract: A bipolar battery (1) comprising a stack of multiple bipolar plates (9) sandwiched between two monopolar plates (6, 8) is disclosed. The bipolar plates (9) each comprise a conductive polymer core (22) and an integrally formed non-conductive polymer surround (4), a layer of cathode material (16) on a first side of the bipolar plate (9), and a layer of anode material (28) on a second, opposite side of the bipolar plate (9). The integrally formed non-conductive polymer surround (4) extends from the conductive polymer core (22) further on one side than the other, such that on one side a first recess (19) is defined for accommodating electrolyte material of the battery (1). The layers of anode material (28) and cathode material (16) are contained within a casing formed at least in part by the integrally formed non-conductive polymer surrounds (4) of all of the bipolar plates (9).

Abstract: The present invention concerns a method for manufacturing a proppant for a particular stimulation fluid, or for manufacturing a stimulation fluid for a particular proppant. The present invention also concerns a proppant for hydrocarbon stimulation, wherein the proppant comprises a plurality of amorphous spherical glass particles which have not undergone any further chemical or thermal treatment, a method of preparing the proppant, and uses of the proppant in hydrocarbon stimulation.

Abstract: Methods and apparatus are disclosed for monitoring incontinence events using inexpensive sensors coupled to an incontinence brief worn by a patient. In some examples of the disclosed technology, a radio frequency identification (RFID) tag is queried to return a sensor value indicating a level of moisture in an incontinence brief. A mobile device carried by a patient caregiver analyzes the sensor value and provides a display indicating a course of action to take, for example, whether to change the patient's incontinence brief.

Abstract: A radio receiver includes a downconverter for downconverting dual sideband signals such as Binary Offset Carrier (BOC) signals from multiple sources to produce an upper and a lower sideband signal, and chip-matched filters for filtering each of the sideband signals. The output of each filter is provided to a series of separate channels, one for each source, where there are at least Early, Prompt and Late gates. Each gate has a nearest-neighbour sampler and a multiplier for multiplying with an appropriate part of a spreading code, a mixer for removing Doppler or other frequency offsets and an integrator. The invention provides a means for demodulating signals such as BOC modulated satellite navigation signals in an efficient manner by using a single downconverter for the received signals of interest from the multiple sources.

Abstract: The present disclosure provides methodologies for manufacturing photovoltaic devices. In particular, the disclosure relates to the use of hydrogen during manufacturing of photovoltaic devices for passivating defects in the silicon and addressing light-induced degradation. The methodologies in the present disclosures take advantage of generation and manipulation of hydrogen in the neutral or charged state to optimise defect passivation. Some of the methodologies disclose use thermal treatments, illumination with sub-bandgap photons, electric fields or defects in the silicon to control the state of charge or hydrogen, move hydrogen to different locations in the device or retain hydrogen at specific locations.
