QM systems has extensive knowledge and expertise in creating vision test solutions. QM has used a range of proprietary vision tools to accommodate the client's in-house standards. QM has created comprehensive vision test solutions using National Instruments' versatile IMAC range. The latter was used to produce a fully integrated vision and functional test station for mobile phones. A particular benefit is the display testing feature. Click here for case study.

To meet the challenge of duplicating the complex communications system in a mine-sweeper, flexibility in configuration and mounting within the constraints of operational panels QM developed COMSIM 16. The unit is a case where the latest technology was used to simulate a novel system. QM Systems supplied a complete solution including consoles, mechanical housings, switch and display panels. The system firmware is loaded from a PC over an RS232 link enabling the user to modify the personality of the system. The system is controlled through an implementation of ARCNET. Generic outstations are linked to the main control unit on a star network for data and a star configuration for audio. The audio is a dual balanced 600 ohm twisted pair. The configuration is bidirectional.

To overcome the problem of being tied to a particular supplier for video conferencing QM Systems developed a CODEC switch. The QM CODEC switch overcomes the interfacing problem by matching the audio and video drive levels for proprietary makes such as Picturetel and CL. The switches are bidirectional between two sources for audio and video switching with level translation and buffered outputs. Return signals are converted back to the original system.

The remote camera control system was developed to control a CCTV system in a Marks and Spencer store through a video conferencing system and deliver pictures to the video conferencing terminal either in the office or a security point. The system comprises a controller/transmitter and a system interface. The controller is a small desktop unit equipped with a keypad for camera selection and joystick controls.

One of the largest building societies and also UK Government bodies wanted to view a discussion group and graphical information at the same time over video conferencing links. The split screen generator allows any two video images to be stacked and transmitted to the far end over the ISDN conferencing link. At the far end the images may be displayed on a signal or separate monitors. Each end is able to stack and send video images simultaneously.
