Title: Portable colour measurement device and system and dye determination system
Inventor: ANDREW HUGH LAURISTON
IPC: G01J3/50
Filed: 2016-11-14
Abstract: A portable colour measurement device 10 has a body 20 including a light source 30 and a sensor 40. A measurement zone 21 within the body 20 accommodates an element 100 to be measured for colour. The light source 30a emits light along a path 31a within the body 20 to the sensor 40, and the measurement zone 21 is in the path. Properties of the element 100 are measured depending on the sensor 40 outputs. The sensor 40 may receive light reflected by the element 100. There may be a second light source 30b and a second path 31b to allow measurement of light transmitted through the element 100. A pair of jaws (22, 23, fig 4) may hold the element 100 within the measurement zone 21. There may be a short-range wireless communications system to communicate measured data to a user device, such as a smartphone. There may also be an interface or base station including a processor to transform received data into a scheme value representing colour. The device 10 may be used as part of a dye determination system to determine the correct hair dye for a desired colour.

Title: Range extension for optical fiber sensing systems
Inventor: TOM PARKER
IPC: G01H9/00
Filed: 2015-12-02
Abstract: In an optical fiber sensing system of embodiments of the present invention one or more optical fiber amplifiers are provided in series with the sensing fiber in order to increase the power of any sensing pulses being sent in a forward direction along the fiber. Optical circulators are provided either side of the optical amplifier, to allow backscattered light to be routed around the forward path optical amplifier. In some embodiments an optical amplifier may also be provided in the backscatter and/or reflections feedback path, to increase the power of the backscatter. In further embodiments signal conditioning circuitry may be used, such that the forward optical pulse signal is filtered and/or reconstructed so as to be more like the original pulse (i.e. typically with less time spreading) when output by the amplifier. In some embodiments this may be done within the optical domain by the provision of appropriate bandpass filters, or in other embodiments electronically, with an incoming pulse being electronically sampled and then fed to a controller, which then electronically controls an optical amplifier to reproduce a re-conditioned (with respect to amplitude, wavelength and time) pulse for onward transmission along the next length of fiber.
