Title: Contact lens steriliser having a thermostat
Inventor: ANDO TETSUYA
IPC: A61L12/04
Filed: 1986-03-14
Abstract: An apparatus for heat-sterilizing contact lenses, particularly soft contact lenses, comprises a housing (3, 4, 5) having a sterilizing chamber (7), heating means (12-15, 31) for heating the sterilizing chamber, and a temperature sensor (17) adapted to detect the temperature of the sterilizing chamber. The temperature sensor comprises a flexible sensor container (18), a material (20) sealed into th sensor container, and an end closure (23) having a rod (21) extending into the body of said material. The material sealed in the container has a melting point or liquefaction point corresponding to a maximum permitted temperature in a zone (19) adjacent the sterilizing chamber. Liquefaction of the material permits the rod to move under a strong bias (27') causing the container to deform and the end closure to move to actuate a switch (9) to turn off heating means. <IMAGE>

Title: Semiconductor switch array
Inventor: ROGERS DENNIS JOHN
IPC: H04Q3/52
Filed: 1986-03-18
Abstract: A semiconductor switch array includes two sets of co-ordinates (1, 2), made from respective layers of metal separated by a substrate of insulating material. At each intersection there is a decode and latch circuit (3) which controls a set of gates for its intersection. In the arrangement shown there are 24 lines in each of the buses, so each such set of gates consists of 24 similar gates which are controlled together. To set up a connection between a bus in one co-ordinate and a bus in the other co-ordinate, a coded signal is applied to lines of one of these buses and this is offered to all decode and latch circuits of that bus. One of these circuits recognises that it is the "wanted" circuit, and responds to close its set of gates to complete the required bus connection. With such an arrangement two or more buses in one direction can be connected to the same bus in the other direction. <IMAGE>

Title: Harmonying the optical axes of combined heat imaging apparatus and sight
Inventor: WEIGEL WOLFGANG
IPC: H04N5/33
Filed: 1986-04-18
Abstract: The invention relates to a method of and circuit arrangement for harmonising opto-electronic axes of a heat image apparatus. In the direction of ray incidence, the heat image apparatus comprises a detector channel with a scanning mirror 4 and rows of detectors 6. The radiated energy received by these latter is depicted on rows of light emitting diodes 9, the radiation from which is reflected via the reproduction side of the scanning mirror 4 and a heat image channel 14 into a periscope 12 in which the observer can make cross hairs coincide with other axes of the apparatus by means of rotating wedges 17 provided in the heat image channel 14 and can therefore harmonise the axes. A scan position sensor 19 senses the reproduction side of the mirror 4 and with the reflected radiation from the scan positions sensor 19, a trigger signal is generated in its own detector. In order to be able to evaluate additionally the harmonisation of axes for an electronic display of a target or of its heat image in a further instrument (which may if necessary be connected to the aiming instrument), there is provided in parallel with the heat image channel a multiplexer channel with a facility for the connection of a tracker, for instance, which together with the rows of light emitting diodes, can be operated through a processor and serve to provide trigger signals from the scan positions sensor for time-synchronous interrogation of the detector signals. <IMAGE>

Title: Driving simulator
Inventor: WONG SIU LEUNG
IPC: G09B9/05
Filed: 1987-08-26
Abstract: A toy driving simulator device comprising a body having a screen on which a driving scene is displayed and a steering wheel for a user to move the image of a vehicle also visible through the screen relative that scene. The driving scene is formed by projecting a segment of an image from a circular disk onto the screen, that disc being rotated about its axis to provide a moving and changing scene on the screen to give the impression of the vehicle driving past that scene. Cam means on the disc correspond with the path in the scene which the vehicle should follow. A cam follower engages the cam means and cooperates with means detecting the position of the vehicle under the control of the steering wheel to detect times when the position of the vehicle does not correspond with the intended path and at such times actuating a warning signal. <IMAGE>

IPC: G10L13/04
Filed: 1989-03-30
Abstract: A user speaks predetermined trigger phrases which are transmitted from an input device such as a multiline telephone 12 to a voice recognition system 20. This associates the trigger phrases with predetermined blocks of text message and, in response to a sequence of trigger phrases, creates a report. The text is then output to a voice synthesizer system 40 for the creation of synthetic voice signals corresponding to the full text of the report and the synthetic voice signals are output to a voice storage and forward system 50 for later retrieval. It also provides a printed copy of the report full text. In one embodiment, an exception dictionary is provided which substitutes replacement words having a modified spelling for exception words whose pronunciation, as synthesized is not considered acceptable. This can be used for hospital radiologists reports.

IPC: H02M1/38
Filed: 1990-05-08
Abstract: Control is provided for prevention of a short circuit between controllable elements used as switching elements in a pulse-width modulation inverter which outputs a variable a.c. voltage or an a.c. indicative of a variable frequency. The pulse- width modulation inverter has a selecting means 80 which selects an output from a processing means 65 within a period during which the result of detection by a current detector 90 falls within a region of substantially zero level and also selects only a signal corresponding to each switching element which effectively acts on the generation of the output current, out of signals generated by a PWM signal generating means during a period other than the above-described period, thereby to output the same as a drive signal for the switching element. The current detector 90 is used to determine the polarity of the output and the control ensures that only the switching elements providing the correct polarity output are allowed to be driven. …<IMAGE>…
