Abstract

An optical source (100) generates optical pulses, and directs them to a first path arrangement (102), which splits and directs them to targets (104, 106). A second path arrangement (108) transfers the optical radiation to a wavelength separator (110), which directs wavelengths to SPAD elements of a detector (112). Unique propagation delays cause receptions of the optical radiation to separate temporally at the SPAD elements. A timing controller (114) triggers detection intervals of the SPAD elements ON/OFF synchronously with the delays of the paths (102, 108) and generation of the pulses, and allows the SPAD elements to detect photons only during the detection intervals that are temporally matched with the interactions. The SPAD elements output electric signals synchronously with the detection intervals for causing them to correspond to distribution of wavelengths of the optical radiation of only one of the targets (104, 106) at each output moment.

Abstract

A method for measuring intracranial dynamics, by performing (2200) an optoelectronic measurement of the intracranial neuronal and fluids dynamics, brain tissue pulsation and glymphatic activity through the cranium by an optoelectronic measurement arrangement (120). Applying (2202), by the data processing unit (150), at least one of the following analyses to electrical signals received from the optoelectronic measurement arrangement (120) and carrying information on said dynamics. At least one of the pulses of the of the dynamics is decomposed for processing with a relation between the characteristic pulses. A moment of statistical analysis of the pulses of said dynamics is determined. A brain fluid, particularly water-hemodynamic, coupling is determined from the pulses of said dynamics based on a definition that a sum of volumes of the brain tissue, cerebrospinal fluid (CSF) and intracranial blood is constant. A ratio between a power spectral density of a fraction of a whole measured frequency band and a power spectral density of the whole measured frequency band is determined. Entropy relating to the electrical signals is determined. A G-index based on said analysis of the electrical signals and a reference, which is based on an analysis of a control group with known and/or estimated intracranial dynamics, is determined, the G-index representing a relative dynamics of the brain.

The first ceramic powder is mixed with NaCl, Li2MoO4 or other ceramic powder having a particle size of 0.5-20 micron, in a ratio of 60-90 vol-% said first ceramic powder and 10-40 vol-% NaCl, Li2MoO4 or other ceramic powder. The obtained ceramic powder mixture is mixed with aqueous solution of NaCl, Li2MoO4 or said other ceramic, in a ratio of 70-90 wt-% the ceramic powder mixture, and 10-30 wt-% the aqueous solution. The obtained homogeneous mass is compressed in a mould for 2-10 min in room temperature and in a pressure of 100-400 MPa. The compressed homogeneous mass is removed from the mould, thereby obtaining electroceramic composite material. Alternatively to the use of the water soluble salt an organometallic precursor compound can be used.

Abstract

A range imaging apparatus comprises a semiconductor laser transmitter, a receiver, and a data processing unit, a field-of-illumination of the semiconductor transmitter and a field-of-view of the receiver being overlapping. The receiver comprises single photon avalanche detector elements arranged two-dimensionally and operate in a Geiger mode. The semiconductor laser transmitter generates optical pulses repeatedly, a single optical pulse of the optical pulses being output as an optical beam with one or more stripes, which are parallel, one above another, and separate from each other. Each of the stripes of optical beams, which are reflected from objects within the field-of-view, illuminates a detector element configuration of the single photon avalanche detector elements. The data processing unit performs, synchronously with the optical pulses repeatedly generated, a selection of single photon avalanche detector elements of the detector element configurations in response to a generation of an optical pulse that illuminates one or more detector element configurations with the one or more stripes, and determines values corresponding to time-of-flights of said optical pulse based on electrical signals from the single photon avalanche detector elements of the selection for performing range imaging.

Abstract

A semiconductor laser source of a transmitter (102) in a range imaging apparatus (100) generates an optical pulse at repeated moments, and outputs spatially separate optical beams towards a target zone (114), such that the semiconductor laser source outputs each of the spatially separate of the optical beams at different moments from each other. A detector (105) of a receiver (104) comprises single-photon sub-detector units, at least two groups of the single-photon sub-detector units have separate field of views towards the target zone (114), and the at least two groups of sub-detector units are associated with different optical beams of the spatially separated optical beams on the basis of the separate field-of-views. A timing unit (106) determines a value corresponding to a time-of-flight of the optical pulse output at each of the repeated moments on the basis of a signal from a group of the sub-detector units associated with an optical beams output at said moment. In an embodiment, the semiconductor laser source comprises a plurality of sub-source units each of which may output a unique optical beam. In an embodiment, the timing unit (106) comprises a selector and a number of time-to-digital converters (108). The receiver selector connects a number of the sub-detector units, which detect the optical pulse (110) and the number of which corresponds to the number of output beams, with the number of the time-to-digital converters (108). In an embodiment, the apparatus (100) comprises an electric power source (192) which supplies a constant electric power to the semiconductor laser source at each of the repeated moments in order to increase brightness of the optical beams. Elongated optical beams may be produced by a laser diode bar (several emitting stripes) and a cylinder lens system or a holographic diffuser. Partially overlapping optical beams may provide illuminated rectangles of the optical beams on the target (112).

Abstract

A semiconductor laser source of a transmitter (102) in a range imaging apparatus (100) generates an optical pulse at repeated moments, and outputs spatially separate optical beams towards a target zone (114), such that the semiconductor laser source outputs each of the spatially separate of the optical beams at different moments from each other. A detector (105) of a receiver (104) comprises single-photon sub-detector units, at least two groups of the single-photon sub-detector units have separate field of views towards the target zone (114), and the at least two groups of sub-detector units are associated with different optical beams of the spatially separated optical beams on the basis of the separate field-of-views. A timing unit (106) determines a value corresponding to a time-of-flight of the optical pulse output at each of the repeated moments on the basis of a signal from a group of the sub-detector units associated with an optical beams output at said moment. In an embodiment, the semiconductor laser source comprises a plurality of sub-source units each of which may output a unique optical beam. In an embodiment, the timing unit (106) comprises a selector and a number of time-to-digital converters (108). The receiver selector connects a number of the sub-detector units, which detect the optical pulse (110) and the number of which corresponds to the number of output beams, with the number of the time-to-digital converters (108). In an embodiment, the apparatus (100) comprises an electric power source (192) which supplies a constant electric power to the semiconductor laser source at each of the repeated moments in order to increase brightness of the optical beams. Elongated optical beams may be produced by a laser diode bar (several emitting stripes) and a cylinder lens system or a holographic diffuser. Partially overlapping optical beams may provide illuminated rectangles of the optical beams on the target (112).

Abstract

An optical time-of-flight distance measuring device comprises a transmitter and a receiver. The transmitter comprises a semiconductor laser for outputting optical pulses of controllably variable temporal widths. The semiconductor laser operates in an enhanced switching regime for the optical pulses of a minimum generable temporal width of the laser. The receiver comprises a matrix of single photon avalanche detector elements of a Geiger mode, a receiver controller, and one or more time-to-digital converters. The single photon avalanche detector elements detect optical pulses reflected from the target to the matrix, and each of the single photon avalanche detector element outputs an electric signal in response to each detection. A number of the time-to-digital converters is smaller than a number of the single photon avalanche detector elements of the matrix. The receiver controller connects at least two of the single photon avalanche detector elements with different time-to-digital converters. The time-to-digital converters connected with the single photon avalanche detector elements provide timings of detected optical pulses on the basis of each output electrical signal for determination of information associated with a distance of the target.

Abstract

Improvements on latency are achieved for highest priority messaging and channel utilization in a time-slotted access channel structure. New superframe structures are presented where scheduled, but unused access slots can be utilized by secondary nodes. The messaging is accomplished by defining user priorities for nodes and the nodes sensing an ongoing transmission in the network. The time slotted channel access structure has at least one access phase which is divided into access slots. In the beginning of the access phase the nodes sense if a highest priority transmission exist and if not, another node with a lower user priority may initiate transmission.

The invention relates to a multichannel electrode used in measuring electrical and chemical activity in biological tissue and a method for manufacturing the multi-channel electrode. For manufacturing the multichannel electrode a carbon fiber and a conductor are first attached together. Electrodes are electrically insulated from each other by directly applying insulation on their surface, or by inserting them in capillary tubes made of glass or plastic. Insulated single electrodes are then integrated into a bunch. If capillary tubes are used as insulator, the bunch is drawn to a fine tip by using heat. In both variations, distance between the tips of the electrodes is 5-50 micrometers. Electro active area at the tip can be precisely adjusted using electrochemical etching and partial insulation with suitable dielectric such as electrophoretic deposition paint. The tips may additionally be coated with suitable material such as carbon nanotubes, conductive polymer, metals of different kind, or synthetic or biological molecules.

Abstract

The present invention provides a method for controlling the growth of microbes grown in a medium to high cell-densities by the fed-batch technology, wherein a two-phase system, having a liquid phase (cultivation medium) and a solid or gel phase, the solid or gel phase provides a source of substrate-delivering polymer which is turned by an enzyme in a controlled way into a growth-limiting substrate or pH adjusting agent. The present invention also provides a method for restricting the synthesis of growth-limiting metabolites and preventing oxygen-depletion in microbial cell cultures.

Abstract

The invention relates to a method and an arrangement for performing triggering and for determining a triggering moment. In the solution, a unipolar electrical pulse of a detector (106, 118) is converted between the detector (106, 118) and a first amplifier (108, 120) succeeding the detector into at least one bipolar electrical oscillation. The bipolar electrical oscillation is amplified with at least one amplifier (108, 120) and triggering is performed at a zero level between the extreme values of the bipolar electrical oscillation. In addition, a triggering moment is determined, at which the amplified bipolar electrical oscillation crosses the zero level between its extreme values.
