Title: Biological sensors
IPC: G01N21/43
Filed: 1989-06-02
Abstract: A surface plasmon resonance (SPR) sensor in which the phenomenon of long-range surface plasmon resonance is used to develop a highly sensitive detector for use in biological, biochemical or general chemical testing. The sensor comprises a laminar structure consisting of a high refractive index glass block (10), a membrane (11) of dielectric material, a thin metal layer (13), and a sensitive layer (14). A sample (15) to be tested is brought into contact with the sensitive layer (14). The refractive index of the dielectric layer and that of the layer (14/15) on the opposite side of the metallic layer (13) should be equal, or nearly so, and the refractive index of the glass block (10) should be higher than this so that total internal reflection takes place at the interface between the block (10) and the membrane (11). Light (1) from a laser source (8) is totally internally reflected at this interface, and the strength of the reflected beam (4) is monitored by a light detector (9). Provided conditions are correct, long-range SPR will take place which will sensitively alter the strength of beam (4) in dependence upon the progress of the reaction between the sensitive layer (14) and sample (15).

Title: Apparatus and method for increased operand availability in a data processing unit with a store through cache memory unit strategy
IPC: G06F9/38
Filed: 1990-01-02
Abstract: In a data processing system in which each of the 
data processing units is implemented using pipeline 
techniques and has a cache memory unit employing a 
store through strategy, the time required to prepare 
a write instruction operand address can be 
substantially shorter than the time required by the 
execution unit to prepare the associated write 
instruction operand. In order to utilize time 
difference, apparatus is included in the execution 
(E-)cache unit for storing the write instruction 
operand address during the preparation of the 
associated write instruction operand. After storing 
the write instruction operand address, a next address 
is entered in an input register of the E-cache unit. 
When the newly entered address is associated with a 
read instruction, does not conflict with the write 
instruction operand address, and produces a "hit" 
signal when applied to the E-cache unit tag 
directory, the read instruction is processed by the 
E-cache unit. When a second write instruction 
operand address is entered in the input register, the 
read instruction operand address conflicts with the 
stored write instruction operand address or the read 
instruction operand address results in a "miss" when 
applied to the E-cache tag directory unit, the 
address is stored in the input register until the 
 
 
write instruction operand has been determined and the 
associated write instruction has been processed by 
the E-cache unit.

Filed: 1990-01-30
Abstract: Conventional night vision goggles are, according 
to the invention, provided with heads up display 
information at the same focus and in the same field 
of view as the intensified image. The heads up display 
information is typically generated by a remotely located

duced from a beam expander or taper (37) into one of 
the eyepieces (20), which eyepiece is modified to include 
an image combiner (45) placed inside its outer lens (52) 
in order to provide substantially the same eye relief 
and physical dimensions as an unmodified eyepiece. The 
image combiner includes a partially reflective mirror 
(46). Additional lenses (41, 42, 43) are provided 
between the heads up display from the beam expander 
(37), and the beam combiner (45), to ensure that this 
additional information is presented to the eye at the 
same focus as the intensified image.

Title: Energy control circuit for a thermal inkjet printhead
IPC: B41J2/05
Filed: 1992-01-24
Abstract: A circuit (10) for controlling the energy 
delivered to a heater resistor (RH) of a thermal inkjet 
printhead. The circuit includes a decoder (12) for 
receiving an address for the heater resistor in a 
multiplexed environment. When the heater resistor is 
addressed, the output of the decoder is level shifted 
through a pair of inverters (24, 26) and transmitted to 
the gate of a PMOS driver (34) that delivers the energy to 
the heater resistor (RH). The PMOS driver (34) responds 
to the voltage level of the adjacent inverter output in 
setting the level of the driver output voltage that is 
applied to the resistor (RH). Feedback circuitry in the 
form of an analog (32) or digital (42) comparator compares 
the driver output voltage (VOUT) against a reference 
voltage (VREF). The comparator's output signal is fed 
back through the level shifter (16) as the inverter output 
that is applied to the gate of the PMOS driver (34). The 
inverter output adjusts the driver output voltage so as to 
maintain the voltage (Vo) across the heater resistor at a 
level that delivers a desired amount of energy to the 
heater resistor (RH).
