A general catalogue in two cross-referenced volumes presents the entire line of motion control components available from a specialist supplier. Available in English and German versions, the catalogue provides full information about linear guides, linear actuators, ball screws, rotary bearings, and other products and accessories. One volume of the catalogue contains technical product information, including load evaluation and life calculations; product tolerances and accuracy values; available options; and mounting information. The other volume presents product details through the medium of dimensional charts and drawings and explains the model number coding for each product. To facilitate navigation, the catalogue features a pictorial product overview at the beginning of the technical-information volume and includes an alphabetical index.

A white paper issued by a US contract manufacturer and provider of related contract testing services discusses how engineers can make the most of packaging validation programmes, and presents available options in the testing of medical device packaging. Specifically addressing package validation requirements for medical devices and combination products, the document, which can be downloaded from the contractor’s website, provides insight into the general requirements of microbiological and physical testing programmes. Its argument is that programmes for validating medical device packaging should be designed to encompass actual product storage and shipment conditions. The paper makes the points that a robust packaging validation regimen is essential, that the programme should include transportation simulation testing with concomitant sterility testing, and that a comprehensive regulatory approach to validation during early product development can save weeks of design revision and testing activities later.

A fully illustrated 12-page design guide describes the types of membrane switches a company offers and provides assistance in determining the suitability of a membrane switch for a particular product or instrument. The booklet includes presentations of various user interfaces with graphic overlays that have such features as embossing, display windows, selective texturing, and interchangeable legends and come in a choice of materials. It also discusses equipment interface criteria and support panels and offers technical specifications. Developed in part to help customers understand the design parameters necessary to solicit quotations, the membrane switch design guide outlines factors to consider with regard to use and installation of each type of switch, including material selection, connectivity, and shielding against electrostatic discharge, electromagnetic interference, and radio-frequency interference.
