Abstract: Control device for a computer mouse. In order to enhance comfort as much as possible and to avoid or even cure RSI phenomena, a control device is proposed with a curved finger- supporting element and thumb-supporting element with varying curvatures. Optimum support for the hand and fingers (thumb) is obtained if there is a certain correlation between the length over which the hand, including the fingers, is supported and the width available for supporting the fingers. This value is preferably in the range 0.3-0.6 and more specifically is 0.45. Furthermore, the curvature and height of the finger-supporting element and thumb-supporting element must be implemented such that they are a function of the length of the control device. According to a particular embodiment the finger-supporting element is implemented such that, when viewed transversely, this descends from the highest point in a circle.

Abstract: An active infra-red surveillance illuminator uses a statistically mono-directional micro-diffractive material overlaid on a bank of light emitting diodes (LEDs) to refract light from the LEDs onto a target image. This delivers energy distribution profiles out to a distance to match the aspect ratios of current wide-angle target and wide-angle camera surveillance systems. The distribution of refracted light is elliptical. This distribution can vary by using different diffractive material in conjunction with various numbers, brightness and angles of the LEDs in an LED bank. The effective range of the illuminators is greatly extended with this type of illumination. By limiting infrared (IR) radiation down to a 10 degree vertical window it renders the IR illumination much more effective for surveillance imaging by providing much more effective power on wide, ground-level scenes, and particularly enables multi-lane license plate capture.
