The radicals L1 and L2 are identical or different and are charge-transfer units. L3 is likewise a charge-transfer unit which is substituted by a group A-X. In this, A is an alkylene group which can optionally be substituted by -SO2-NH-, -S-, -O-, -COO- or -CO-NH-, and X is an aldehyde, carboxyl, amino, hydroxyl, thiocyanato group, halogen or a phosphite or a phosphate group or a modified phosphate group, for example a phosphonate or thiophosphonate group or any other suitable group. The RNA or DNA sequence is covalently linked, either in modified form or in unmodified form, directly or via a spacer group by reaction with the ruthenium complex. The charge-transfer units L1, L2 and L3 can be identical or different and can be bipyridyl, bathophenanthroline or banzbathophenanthroline, each of which can optionally be substituted.

Abstract: A method and apparatus for synchronizing two inde­pendent rasters, such that a standard TV video and a high resolution computer generated graphics video may each be displayed on a high resolution graphics monitor. This is accomplished utilizing dual frame buffers. A TV frame buffer, comprises a dual port VRAM, with the serial and random ports operating asynchronously. The primary port receives incoming TV video synchronously as it comes in, and the secondary port reads the TV video out synchronously with the high resolution graphics monitor. A high resolution frame buffer in a computer is utilized to store high resolution graphics which is read out synchronously with the high resolution graphics monitor. A switch­ing mechanism selects which of the TV video and the high resolution graphics video is to be displayed at a given time. The TV frame buffer includes an on screen and off screen portion. The computer provides com­puter data, including high resolution graphics data and audio data to the TV frame buffer, with the graphics data being stored in the on screen portion and the audio data being stored in the off screen portion. The audio data is read out to an audio circuit for replay. The graphics data is combined with the TV video for purposes of windowing.

An optional load device (14a), an optional pull-down device (12), an optional second capacitor (13), an optional string of diode-connected devices (10), and an optional feedback device (15) may be included. Device channel lengths are specified for proper operation. In one embodiment, the circuit includes only a detector field-effect transistor and a load field-effect transistor, the detector transistor having a channel length substantially longer than the channel length of the load transistor. 
     The circuit described and claimed herein is immune to the unpredictable behavior of static logic gates during the initial part of the power-on transient when the supply voltage is less than the threshold voltage of the integrated circuit transistors. In particular, the circuit does not have a node connected to both a static pull-up path and a static pull-down path, both of which are on at the same time, forming a linear circuit.

Abstract: An amplifier which has special application as an induction coil driver (10). A multi-frequency signal is used to modulate the pulse width of a square wave, resulting in a pulse modulated signal (70). The pulse modulated signal (70) is divided into two delay signals. The falling edge of each pulse is delayed in one of the delay signals, while the rising edge of each pulse is delayed in the other delay signal. This creates a "dead band" between the two signals for each pulse. The signals are used to drive two metal oxide semiconducting field-effect transistors (108,110), which are connected to positive and negative power supplies (V+,V-). The switching of the MOSFETs (108,110) occurs during the dead band which, when combined with a novel inductor-diode (126,128) circuit, results in high-efficiency power transfer. The amplified modulated signal is then subjected to a low-pass filter (24) which cancels out the square wave carrier and switching noise. The amplified analog signal may then be applied to a non-tuned induction coil (26a).

Abstract: A damped cradle (22) for a pressure sensitive device (10) is constructed in a unitary form. The cradle has a base that is attached to a substrate (15). Extending upward from the base are side arms (24) with pairs of spring, or compliant, tips (25) that contact the sides of the pressure sensitive device. Also extending upward from the base over the top of the pressure sensitive device are spring arms (26) with compliant tips (27) that contact the top surface of the pressure sensitive device in non-active areas. Vibrational forces in lateral (X-Y plane) directions are damped by friction between the bottom of the pressure sensitive device and the surface of the substrate, and vibration motion in the vertical, or Z, direction is stopped by enough spring force to overcome the maximum acceleration force the crystal mass encompasses for a given application. The spring forces of the spring tips and spring arms are balanced to produce a near zero pressure on the pressure sensitive device in both static and dynamic modes.
