Abstract: An electronic device for measuring an ambient temperature (Tair) of the environment of an electronic device is described. It comprises at least one integrated infrared sensor, a blinded window preventing infrared radiation to directly impinge on the integrated infrared sensor and being in thermal contact with the environment as well as with a cover of the device resulting in the blinded window being at a surface temperature (Tsurface). The at least one integrated infrared sensor is adapted for sensing the temperature of the blinded window (Tsurface). The device also comprises at least one absolute temperature sensor for measuring a temperature of the at least one infrared sensor (Tsensor) itself, and a processing means for determining a temperature difference (ΔT) between the sensed surface temperature (Tsurface) and the temperature of the infrared sensor (Tsensor) and for calculating based thereon the ambient temperature (Tair).

Abstract: A toggled buffer memory apparatus comprising a first memory block (134) arranged to support the first memory function over a first time frame and to toggle to support the second memory function over a second time frame. A second memory block (136) is also arranged to support the second memory function over the first time frame and to toggle to support the first memory function over the second time frame. A data input and a self-test block are respectively operably and selectively coupled to the first and second memory blocks. A controller is arranged to control toggling of the memory blocks (134, 136) which are each arranged to toggle between the first and second memory functions in respect of time frames subsequent to the second time frame. The self-test block is arranged to test the first memory block subsequent to the first memory block performing the first memory function and prior to toggling to perform the second memory function, and to test the second memory block subsequent to the second memory block performing the first memory function and prior to toggling to perform the second memory function.

Abstract: A method of manufacturing a sensor device (100) comprises providing (200) a package (102) having a first die-receiving subframe volume (104) separated from a second die-receiving subframe volume (106) by a partition wall (116). An elongate sensor element (120) is disposed (202) within the package (102) so as to bridge the first and second subframe volumes (104, 106) and to overlie the partition wall (116). The elongate sensor element (120) resides substantially in the first subframe volume (104) and partially in the second subframe volume (106). The elongate sensor element (120) is electrically connected within the second subframe volume (106).

Abstract: An oscillator-based sensor interface circuit includes an oscillator and a switching means is arranged for switching between at least two signals to be applied to the oscillator via that input. At least one of the signals is an electrical signal representative of an electrical quantity. A counter is arranged to count a number of cycles produced by the oscillator. A control logic is arranged to control the switching means and to derive a control output signal from a first number of counted oscillator cycles. A feedback element is arranged for converting a representation of the control output signal into a feedback signal used directly or indirectly to maintain a given relation between the first number of counted oscillator cycles.

Abstract: An infrared sensor assembly for sensing infrared radiation comprises infrared sensing elements and the infrared sensing compensation elements that are different so that, for a same flux on the infrared sensing elements and the infrared sensing compensation elements, the radiation responsive element of the infrared sensing elements absorbs more radiation than the radiation responsive element of the infrared sensing compensation elements, as to receive substantially more radiation than the radiation responsive element of the infrared sensing compensation elements. An output of the sensor array is a subtractive function of a sum of the signals of the plurality of infrared sensing elements and a sum of the signals of the plurality of the infrared sensing compensation elements such that at least linear and/or non-linear parasitic thermal fluxes are at least partly compensated for.
