Title: An apnoea monitor for use during sleep
Inventor: JENKINS CHRISSO VESSELINOVA
IPC: A61B5/113
Filed: 1988-01-11
Abstract: An apnoea monitor for detecting both central and obstructive apnoeas comprises two microphones 1, 2 or other electric transducers for positioning adjacent breathing passages being monitored and respond to the sound of breathing. The output of the transducer 1, 2 is connected to amplifiers 3, 4. The threshold voltage of a comparator amplifier 5 is set so that a train of pulses is emitted for normal breathing. These are applied to a NAND gate 6 and a timer 7 pre-set for determining the minimum period to have occurred, e.g. 6 or 12 secs. A D-type flip-flop 8 and NAND gates 9, 10 are designed so that an output is emitted if there is cessation of air-flow within the period and the output is applied to an LCD counter 11 for displaying the total number of apnoeas. An audio-visual alarm 14, 15 is triggered by a parallel circuit 6 - 10 and controller 12 if there is a prolonged apnoea and this is reset by a button 16 without affecting the counter 11. <IMAGE>

Title: Frequency synthesisers
Inventor: BROWN DAVID ALAN
IPC: H03L7/16
Filed: 1988-03-15
Abstract: A frequency synthesiser for use in a radar or a frequency hopping equipment comprises a frequency adaptive divider- less phase lock loop 100 having elements in its feed-back path for mixing selected local oscillator frequencies 2L0; 40 or 60 with a portion of the loop output. A wide loop band-width for fast switching of frequency channels and high spectral purity of output are obtained. In an input control logic 400, the desired output frequency is preset manually or automatically by an external source and an output signal 1 pre-tunes the loop oscillator to desired output frequency and control signals 3-5 select the required local oscillator frequencies 2L0, 40, 60. A phase control signal 2 is applied to the loop phase/frequency detector. The reference unit 300 includes a single crystal oscillator and provides a number of different fixed frequencies, some of which are applied to a direct synthesiser unit 200 to derive a selectable local oscillator frequency 2L0. The main loop operates over a number of sub-bands in each of which 2L0 is switchable over a fixed range with a frequency spacing. <IMAGE>

Title: Method and system for high speed, 3-D imaging of an object at a vision station
Inventor: SVETKOFF DONALD J
IPC: G01B11/03
Filed: 1988-04-07
Abstract: A method and system for high-speed, 3-D imaging of an object (not shown) at a vision station including a flying spot laser scanner (not shown), a dynamically configurable spatial filter 33, 34 and a diffuser 35 for spatial averaging (smoothing), which are used in conjunction with a variable transmission filter 36 in an optical depth or height sensing system. The reflected laser signal received by the sensing system is first spatially filtered and averaged at 33, 34, 35 and then spin at 39 into first and second beams 40, 41 which are imaged onto a pair of highly sensitive photodetectors (45, 46, Figure 5) which introduce capability for high-speed, 3-D sensing under low light level conditions. The first split beam passes through the variable transmission filter 36 which is used to encode position which, in turn, is proportional to the depth or height of the object. The second or reference split beam 41 is provided to compensate for changes in the reflectance of the object and the power of the laser scanner. A high-speed signal processing unit 51 normalises the signals from the photodetectors to lie within a predetermined range and computes the ratio of the transmitted signal to the sum of the reference signal and the transmitted signal to determine depth or height information. The signal processing unit also contains noise rejection circuitry which is activated during "off" and "on" periods of laser diode TTL modulation and includes feedback control for pulse amplitude modulation of the laser diode source if necessary to increase dynamic range of the system. The object may be a printed circuit board. <IMAGE>

Title: Filament driver for dimmable fluorescent lamp
Inventor: YATES GREGORY
IPC: H05B41/392
Filed: 1988-04-27
Abstract: A filament driver circuit 33, interposed between a fluorescent lamp 30 and a phase controlled dimmer 32, comprises a transformer 38 having a primary winding 39 connected to the dimmer 32 and secondaries 40 connected to the lamp filaments, and a high pass filter which passes to the filaments only harmonic components of the output voltage from dimmer 32. The filter may be an active device, or may be formed by the primary 39 and a capacitor 41. A bleed device 43 discharges capacitor 41 before each firing cycle of the dimmer 32 and may be formed by a switched device or a resistor such as an incandescent lamp. Circuit components may be arranged so that secondaries 40 have an output that rises from 3 volts with the dimmer 32 at a maximum light setting, to 4.5 volts with dimmer 32 at a minimum light setting. The transformer 38 may have a further secondary (44), (Fig. 4) auto wound with primary 39 to provide an increased lamp starting voltage, a capacitor (45) acting effectively to open circuit secondary (44) when the lamp is operating. <IMAGE>

Title: Message network monitoring
Inventor: HARPER JOHN ANTHONY
IPC: H04L12/14
Filed: 1992-10-01
Abstract: A digital message routing network has at least some nodes at which messages are monitored for accounting purposes. Such a node contains means for generating and compressing accounting digests, each of which consists of a key K representing the nature and route of the message and a value V associated with the message. For each message, a digest is produced in register 30, and copied into a location in a first memory 22D at a location determined by hashing its key; further digests with the same key are compressed into the digest already in that location. A second memory 23D is operated as a cyclic buffer with head and tail counters HDCT 40 and TLCT 41. The address of the head of the buffer, ie the valid area of memory 23D, is included as an index I in each digest in the first memory 22D as that digest is created. Each time a digest is created or changed in the first memory 22D, it is copied into the second memory at the location in the second memory determined by its index. Digests are read out from the second memory in blocks; the corresponding digests in the first memory thereby become invalid, and have to be restarted by initializing their values and giving them new indexes. <IMAGE>

IPC: F02P17/12
Filed: 1992-12-09
Abstract: In a system which detects a misfire in an internal combustion engine, the detected value (17) of the sparking voltage at a plug (16) is compared (5b) with a first predetermined value (Vmis1) and the degree to which the detected value of the sparking voltage exceeds the first predetermined value is measured; this is compared (5b) with a second predetermined value set in dependence on detected values of operating parameters of the engine; and it is determined based upon results of the latter comparison whether or not a misfire occurred in the engine. The determination of misfire is inhibited when the engine is in a predetermined operating condition. <IMAGE>

Title: Digital processor for simulating operation of a parallel processing array
Inventor: JOHNSON MARTIN
IPC: G06F15/16
Filed: 1993-02-03
Abstract: A digital processor for simulating operation of a parallel processing array incorporates digital processing units (P1 to P8) communicating data to one another via addresses in memories (M0 to M8) and registers (R11 to R41). Each processing unit (e.g. P1) is programmed to input data and execute a computation involving updating of a stored coefficient followed by data output. Each computation involves use of a respective set of data addresses for data input and output, and each processing unit (e.g. P1) is programmed with a list of such sets employed in succession by that unit. On reaching the end of its list, the processing unit (e.g. P1) repeats it. Each address set is associated with a conceptual internal cell location in the simulated array (10), and each list is associated with a respective sub-array of the simulated array (10). Data is input cyclically to the processor (40) via input/output ports (I/O5 to I/O8) of some of the processing units (P5 to P8). Each processing unit (e.g. P1) executes its list of address sets within a cycle at a rate of one address set per subcycle. At the end of its list, each of the processing units (P1 to P8) has executed the functions associated with a conceptual respective sub-array of simulated cells (12), and the processor (40) as a whole has simulated operation of one cycle of a systolic array (10). Repeating the address set lists with further processor input provides successive simulated array cycles. <IMAGE>
