摘要： An apparatus (1) for adjustably changing the polarisation state of incident light having at least a first wavelength. The apparatus (1) includes a polarisation changing optical metasurface (OMS) (3) arranged to reflect light of a first polarisation state, and to transmit light of a second polarisation state, said second polarisation state being different to said first polarisation state. The apparatus (1) also includes a mirror (9) arranged to reflect the transmitted light of the second polarisation state, wherein the apparatus (1) is arranged to move the mirror (9) and/or the polarisation changing OMS (3) relative to one another to alter a separation between the polarisation changing OMS (3) and the mirror (9), thereby altering a phase difference between the light reflected by the polarisation changing OMS (3) and the light reflected by the mirror (9) such that a combined polarisation state of light reflected by the apparatus (1) is adjustable.

摘要： A hearing protection device (500) arranged to provide an acoustic barrier is disclosed. The hearing protection device (500) includes a microphone (502) arranged to measure sound behind the acoustic barrier. The device (500) determines whether a sound level characteristic of the sound measured by the microphone (502) is above a predetermined threshold. When the sound level characteristic measured by the microphone (502) is above the predetermined threshold, the device (500) compares the sound level characteristic of the sound behind and outside the acoustic barrier to determine an attenuation of the device (500). If the determined attenuation is below a cut-off level of attenuation, the device (500) provides an alert.

摘要： A radio frequency receiver is provided that comprises an antenna (2), an RF amplifier (36), at least one down conversion mixer stage (16, 18) and a variable notch filter. The at least one down-conversion mixer stage (16, 18) is arranged to act on signals provided by the RF amplifier (36) and is tuned to a tuned frequency ft which is selected from a plurality of possible tuned frequencies corresponding to a frequency of the RF signal to be received at the antenna (2). The variable notch filter is arranged to act on signals passing from the antenna (2) to the RF amplifier (36) and has a resonance frequency fr which is selected from a plurality of possible resonance frequencies such that fr = ft /n where n is a whole number between 2 and 10. The variable notch filter thereby acts to attenuate signals from the antenna (2) at said resonance frequency.

摘要： A voltage regulator (2) is arranged to receive an input voltage (V in ) and produce a regulated output voltage (V out ) and comprises: a current source transistor (M source ) and a current sink transistor (M sink ) arranged to provide the output voltage at a node therebetween; a first error amplifier (10); and a second error amplifier (12). The first error amplifier is arranged to apply a first control voltage to the gate terminal of the current source transistor, wherein the first control voltage is dependent on the difference between the feedback voltage (V fb ) and the reference voltage (V ref ). The second error amplifier arranged in parallel to the first error amplifier, the second error amplifier being arranged to apply a second control voltage to the gate terminal of the current sink transistor, wherein the second control voltage is dependent on the difference between the feedback voltage and the reference voltage. The feedback voltage is derived from the output voltage.
