Abstract: An atomizing pump dispenser which includes a valve member (11) having a flattened top so that the diameter of the sealing area (14) in the outlet is increased substantially. A recess (21) within the valve member (11) is modified to provide conical ball sealing portions (27) tapered at predetermined angles to provide a tight seal between the ball (23) and the valve member (11). The innermost end of an inner hollow part (15) of the valve member (11) is a reduced diameter portion (18) such that the initial movement of the valve member (11) is easier. This in effect, tricks the user's finger by easing the initiation of movement of the actuator so as to give the feel of free movement. The inner part (15) of the valve member (11) is provided with a molded-in slotted protrusion (16) for breaking the seal between the valve member (11) and a flexible annular seal, thus alleviating the creation of the vacuum caused by the seal between the ball (23) and the ball seat.

Abstract: There is disclosed a helmet mountable display system which, in the stereoscopic version, includes separate optical paths for providing respective images to the left and right eyes of an observer for stereoscopic viewing, these paths sharing in common, however, a mechanical scanning arrangement. Each of a first and second plurality of spaced apart, substantially point light sources (14,15) supply a respective group of modulated rays of light. The rays of each group are collimated by a respective input lens (16,18) and the collimated rays from each input lens are directed so that their envelopes all intersect at the same point. A horizontal (27) and a vertical (25) deflect­ing surface are disposed on opposite sides of the inter­section point. Electro-mechanical drivers (26,24) move the surfaces which scan all the collimated rays. The scanned rays from each group are focused onto a respective screen (32,34) by a respective output lens (28,30) to form a raster scanned image. Preferably the screens are divided into a plurality of contiguous zones with a ray from each light source assigned to a corresponding zone, which reduces the vertical scan angle excursions required. Simultaneous scan lines from the rays are displayed in each zone on the screen which reduces the video bandwidth requirement of the system. The image from the screens (32,34) is supplied to the inside surface of a visor from which it is reflected to a corresponding eye of the observer.

Abstract: A control processor in a robotic system treats optically sensed locations along the seam path ahead of the tool, which are classified in relation to elapsed distances and identified in 3-D coordinates and 3-axes tool orientation, to apply in real time and under feedforward a control signal representing the error between anticipated tool position and anticipated sensed location on the path. In the process, the anticipated sensed location is obtained by interpolation between actually sensed locations. A taught path is recovered from the robot. The control processor operation is also based on elapsed distances and related to actual tool position provided by the robot.

Abstract: A high speed, high performance CMOS to GPI interface circuit is disclosed. The interface circuit contains an input stage  (21), clamping circuitry (22), an output stage (23) and feed­back circuitry (26). The clamping circuitry (22) clamps the voltage level presented to the output stage (23) at a level below the power supply voltage when the input from the CMOS circuit is at a high logic level. As the voltage level of the signal presented to the GPI circuitry rises, feedback circuitry (26) feeds this signal back to the clamping circuit­ry, which in turn decreases the voltage level presented to the output stage. This assures the signal presented to the GPI circuit falls within the speci-fied voltage level from 1.51 and 2.2 volts. The feedback circuitry (26) contains a single pole filter that filters out high frequency reflections presented to the feedback circuitry (26), and a slew rate limiter that slows the rise and fall of the voltage level presented to the output stage (23) thereby reducing noise on the power supply and ground lines. The feedback circuitry (26) uses bilateral (push-pull) gain tech­niques to control the voltage level presented to the output stage (23) as the input signal from the CMOS circuit swings from low to high logic levels. The interface circuit is made up exclusively from standard threshold FETs. The interface circuit also contains discharge circuitry (24) that discharges the voltage level of the feed­back circuitry (26) when the input from the CMOS circuit chang­es from a high level to a low level, thereby preventing a latch-up condition.

Abstract: A multimedia protocol interface for 64 kbit/s data flow, organised according to the frame structure specified in CCITT Recommendation H221 and transmitted and received according to the standard 64 kbit/s protocol to 256 kbit/s IOM protocol, which is apt to operate autonomously or aided by an external microprocessor and comprises a receiver, a transmitter, a control block and means for the local test of the operation of the interface itself. 
     The external microprocessor can read both the received data and the information relevant to the receiver conditions, and can also send data to be transmitted or can read information relevant to the transmitter conditions. 
     The receiver receives the data and clock and synchronism signals and emits at the output the received data, associated with timing signals useful for the external devices connected to the interface for data recovery. 
     Analogously, the transmitter emits the data, receives clock and synchronism signals and supplies data and timings to the external devices. 
     The local test is carried out by verifying whether the receiver succeeds in recovering the synchronism from the signal emitted by the transmitter of the same interface, under microprocessor supervision, and whether the data are correctly transmitted and received.

Abstract: In an optical unit (2) incorporated in a laser beam printer, a laser beam generated by a laser diode (l2) is converted by a group of conversion lenses (l0) into a laser beam having a predetermined-size cross section. The laser beam is directed toward a photosensitive body (90) by a scanner unit (50), so as to scan the photosensitive body. A focusing lens (72) allows the rotating angle of the reflecting faces of the scanner unit to correspond to a desirable point on the surface of the photosensitive body (90). In other words, the rotating angle is made to correspond to the distance between the optical axis center determined with respect to a main scanning direction and a point to which the laser beam is irradiated for scanning. The conversion lenses (l0) include at least one aspheric glass lens (l4). The conversion lenses further includes a pair of plastic lenses (l6, l8) which have substantially the same power and opposite polarities with respect to either the main scanning direction or a sub-scanning direction. Among the lenses (l4, l6, l8) mentioned above, that lens (l6) which is located closest to the glass lens (l4) is integral with the laser diode (l2). The focusing lens (72) is formed of a material having substantially equivalent characteristics to those of the paired plastic lenses.
