Abstract

A method for autoconfiguration of a plurality of nodes in a linear network allows extracting the address and position of each node. The method includes applying an identifier field for transmitting to the bus the bit sequence of the identifier of a chosen node. Then for at least for the first node to the last but one node, a field comprising a predetermined bit sequence is applied. The field comprises dominant bits, so a current is transmitted. Then, a further field is applied for transmitting any stored direction bit associated to that node and obtained in any previous iteration. The iteration continues by choosing a node different from a node chosen in any previous cycle, starting the communication, until all nodes are identified.

Abstract

A method for autoconfiguration of a plurality of nodes in a linear network allows extracting the address and position of each node. The nodes are identified by a unique identifier. The method comprises choosing a node in a network and extracting its identifier, and for the first node to the last but one node, transmitting a current in the network from the chosen node, and reading the direction of the current flowing through at least the nodes not chosen in previous iteration cycles. The identifier is linked with the direction of the current for said not chosen nodes, obtaining the position of said not chosen nodes relative to the chosen node. These steps are repeated by choosing a different node not chosen before.

Abstract

In a heating appliance comprising a substrate for receiving an item of cookware, a method of measuring reflectivity comprises emitting a time-varying electromagnetic signal from a first side of the substrate, a portion of the time-varying electromagnetic signal propagating through the substrate. Electromagnetic radiation is then received at the first side of the substrate, the received electromagnetic radiation comprising a background ambient component received and a component reflected by the substrate. A gain factor is applied to translate the received electromagnetic radiation to a receive electrical signal. An offset signal component is then identified from the receive electrical signal, the offset signal component arising from the background ambient component of the received electromagnetic radiation. The gain factor from the offset signal component is then estimated using a characterisation of the offset signal component, and the reflectivity is calculated using the receive electrical signal and the estimated gain factor.

Abstract

A method of manufacturing a sensor device comprising: configuring a moulding support structure and a packaging mould so as to provide predetermined pathways to accommodate a moulding compound, the moulding support structure defining a first notional volume adjacent a second notional volume. An elongate sensor element and the moulding support structure are configured so that the moulding support structure fixedly carries the elongate sensor element and the elongate sensor element resides substantially in the first notional volume and extends towards the second notional volume, the elongate sensor element having an electrical contact electrically coupled to another electrical contact disposed within the second notional volume. The moulding support structure carrying (102) the elongate sensor element is disposed within the packaging mould (106). The moulding compound is then introduced (110) into the packaging mould during a predetermined period of time (112) so that the moulding compound fills the predetermined pathways, thereby filling the second notional volume and surrounding the elongate sensor element within the second notional volume without contacting the elongate sensor element.

Abstract

A method of generating a de-interlacing filter comprises: analysing a pixel array comprising an interlacing pattern of pixels. The interlacing pattern of pixels comprises first and second pluralities of pixels configured to be read during a first measurement subframe and a second measurement subframe, respectively. An n-state representation of the interlacing pattern of pixels is generated and distinguishes between the first plurality of pixels and the second plurality of pixels. The n-state representation of the interlacing pattern is translated to a spatial frequency domain, thereby generating a spatial frequency domain representation of the n-state representation of the interlacing pattern. A DC signal component is then removed from the spatial frequency domain representation of the n-state representation of the interlacing pattern, thereby generating a DC-less spatial frequency domain representation. A kernel filter is then selected and configured to blur before convolving the DC-less spatial frequency representation with the selected kernel filter.

The control circuit is adapted for controlling the first magnetic sensor to measure magnetic fields under presence of a first set of magnetic fields, and for controlling the second magnetic sensor to measure magnetic fields under presence of a second set of magnetic fields generated by the inductors. The control circuit calculates a relative sensitivity matching value that converts magnetic field values measured by the second magnetic sensor to a comparable magnetic field value measured by the first magnetic sensor or vice versa. The control circuit is further adapted for correcting a measurement by the second magnetic sensor using the relative sensitivity matching value to produce a corrected measurement, and for calculating a magnetic field gradient by combining a measurement by the first magnetic sensor with the corrected measurement.

Abstract

A thermal imaging apparatus comprising: a thermal detector device (100) comprising an array of thermal sensing pixels (102) and signal processing circuitry (104) coupled to the detector device (100). The circuitry (104) supports a background identifier (110) and a pixel classifier (112), the background identifier (110) comprising a common intensity identifier (114) and an expected background intensity calculator (116). The background identifier (110) receives pixel measurement data captured by the detector device (100) in respect of pixels of the array (102) and the common intensity identifier (114) identifies a largest number of substantially the same pixel intensity values from the pixel measurement data. The expected background intensity calculator (116) uses the largest number of substantially the same pixel intensity values to generate a model of expected background intensity levels. The pixel classifier (112) uses the model to determine whether an intensity measurement by a pixel (118) of the array (102) corresponds to a background or an object in an image.

The carrier signal is phase shifted in response to the code sequence (406) depending upon a value of a symbol (408, 410, 412, 414, 416). The modulated carrier signal is applied to a light source, thereby modulating the light which is emitted. An electrical sensor signal is generated in response to received reflected light. A plurality of predetermined phase offset values is applied to the modulated carrier signal, and a plurality of electrical output signals is generated and stored by applying said resulting signal to the electrical sensor signal in accordance with the indirect time of flight measurement technique over the exposure time period. Each symbol (408, 410, 412, 414, 416) has a duration greater than the carrier signal period.

Abstract

An indirect time of flight range calculation apparatus comprises a light source, a photonic mixer that generates a plurality of output signals corresponding to a first plurality of phase values. A signal processor is also provided to calculate a first vector and a first angle from the first vector. The photonic mixer generates a second plurality of electrical output signals corresponding to a second plurality of phase values. Each phase value of the second plurality of phase values is respectively offset with respect to each phase value of the first plurality of phase values by a predetermined phase offset value. The signal processor processes the second plurality of electrical output signals in order to calculate a second vector, and de-rotates the second vector calculated and calculates a second angle from the de-rotated vector before offsetting the second angle against the first angle, thereby generating a corrected output angle.

A controller receives the measurement and correction signal in both the first and second state, and calculates an error value indicative of the measurement error and/or a sensor readout value that is corrected for the measurement error by taking the measurement and correction signal into account as obtained in both the first and second state.

  • G01R 33/00 - Arrangements or instruments for measuring magnetic variables
