A cable protection system is provided. The cable protection system comprises one or more annular elements for location around at least part of an item in use. Each annular element comprises a first shell member and at least a second shell member. The first and/or at least second shell member having a cavity defined therein, therethrough or therebetween for the location of said item part in use. The first and at least second shell members are arranged to move between an open position, wherein said item part can be located in or removed from the cavity in use, and a closed position, wherein access to the cavity is restricted or prevented. Connection means are provided for connecting the first and at least second shell members together in use. The first and at least second shell members are non-overcentre or non-overlapping shell members, and the connection means are arranged to be connected to the first and/or at least second shell members in a circumferential direction in use.

Acoustic models accurately predict ear-canal acoustics in children using standard clinical immittance measures to improve the accuracy of hearing aid fitting when measurements cannot be made in the child's ear canal. Physical models of ear canal geometry have been associated to indirect acoustic estimates, which makes is possible to develop models that can predict physical and acoustic characteristics of the ear canal. Such a model predicts ear-canal geometry and acoustics to product earmolds without the need for ear impressions or repeated verification. The combination of predicting ear canal geometry and acoustics improves the quality of hearing aid fitting in children, positively impacts developmental outcomes, and reduces the burden for children and their families. This is especially seen in rural areas, developing countries, and other areas where the ratio of patients to care provides is reduced.

Dimension measurement apparatus is provided including: image capture means for capturing one or more images of at least one item in use; and micro-processing means arranged in use to receive and process the one or more captured images, and calculate one or more dimensions of the at least one item in the one or more captured images.The image capture means are arranged to capture a plurality of the images of the at least one item in a pre-determined period of time in use. The micro-processing means are further arranged in use to: identify the presence of one or more objects, which may or may not include the at least one item, within each of the plurality of captured images in the pre-determined period of time to provide a measure of identified objects; identify one or more of the captured images from the plurality of captured images for which the measure of identified objects is the lowest during the pre-determined period of time; and use the identified one or more captured images for which the measure of identified objects is the lowest to calculate one or more dimensions of the at least one item in use.

Image capture means positioning apparatus is provided including image capture means capable of capturing one or more images in use; visual identification means arranged so as to be capable of being captured in the one or more images taken by the image capture means in use; and micro-processing means. The micro-processing means are arranged to undertake the following: a) process the one or more images captured by the image capture means and identify a current image position of the visual identification means in said images; b) compare the current image position of the visual identification means in the images to a previously known image position of the visual identification means; c) determine if there is a difference between the current image position of the visual identification means and the previously known image position of the visual identification means and, if a difference is detected, initiate a pre-determined action or actions in respect of the same.
