A projection apparatus for generating a moving star field and a cloud-like effect comprises a means for generating a cloud-like effect using at least one non-coherent light source, a means for generating a moving star field using at least one coherent light source and a means for regulating and supplying electric power. The means for generating cloud-like effect using at least one non-coherent light source comprises at least one pair of condenser lenses and an interferential filter wheel rotated by a motor, disposed between at least one pair of condenser lenses. The means for generating the moving star field using a coherent light source comprises a grating wheel rotated by a motor and a diffractive optical element disposed between the at least one coherent light source and the grating wheel.

An electrostatic discharge protection circuit employing an extended resistive structure having bimodal resistance characteristics in series with an input/output buffer circuit and an input/output electrical contact pad on an integrated circuit. The extended resistive structure is integrally formed with the device or devices in the buffer circuit most susceptible to damage due to ESD breakdown effects. In a first resistance mode during normal circuit operations, the resistor has a low resistance value and introduces virtually no additional load to the input/output buffer circuitry. In a second mode of operation during ESD discharge, the resistor has a second significantly higher resistance which reduces current values during the ESD event thereby protecting the buffer circuit. Thick oxide snap-back device is also employed to provide a parallel ESD discharge path with low power dissipation.

In an area image sensor, the on-chip capacitances driven by the sensor photosite elements during sensor readout are made equal. This is accomplished by adjusting the lengths and widths of the conductors (and leads) carrying the output signals so that each signal conductor (and lead) covers equal areas on the sensor substrate. Additionally, the invention teaches fabricating individual integrated circuit buffer amplifiers on the sensor chip which isolate the normalized capacitances from loading effects due to externally connected circuits.

An electrostatic discharge protection circuit for an integrated circuit employing a segmented field effect buffer transistor between the input/output pad and the active devices on the integrated cicuit. An extended resistive structure is configured in series with the segmented buffer transistor and the input/output electrical contact pad. The extended resistive structure is integrally formed with the individual segments of the buffer FET. The resistive structure may be implemented as an extended n well structure adjacent the FET segments. In a first resistance mode during normal circuit operations, the extended resistive structure has a low resistance value and introduces virtually no additional load to the input/output buffer circuitry. In a second mode of operation during ESD discharge, the resistive structure has a second significantly higher resistance which reduces current values during the ESD event thereby protecting the buffer circuit. A thick oxide snap-back device is also employed to provide a parallel EDS discharge path with low power dissipation.

A computer-implemented method, computer program product, and system is provided for creating calculated metrics. In an implementation, a method may include providing a user interface including a calculator with a plurality of buttons. The method may also include receiving, via the user interface, a selection of at least one stored metric and a selection of at least one operation, resulting in a new metric. The method may further include storing the new metric with a new metric name.
