Title: Safety device for telescopic boom
Inventor: TORVINEN VOITTO
IPC: B66F17/00
Filed: 1990-12-24
Abstract: An outreach limit (11) is provided in order to prevent overloading leading to overturning of the boom crane (10) of a telescopic boom having a main boom (12) and at least one extension boom (17). The support points (19, 20) between the main boom and the extension boom have been connected to the main boom so that the distance (a) between the support points will remain constant when the extension boom is pulled out. The function of the outreach limit is based on the measurement of main boom deflection. According to the invention, the outreach limit (11) involves a measuring bridge (31) fastened at both ends (21, 34) to the main boom (12). The bridge will bend to the opposite direction compared with the main boom so that when the outreach limit is in operation, its sensors (24, 25 and 30) will feel the total deflection of the main boom and the measuring bridge. <IMAGE>

Title: Method and apparatus for recovering data, such as teletext data encoded into television signals
Inventor: WOODWARD THOMAS R
IPC: H04N7/26
Filed: 1992-03-11
Abstract: A receiver for recovering serial digital data, such as teletext, achieves an effective sampling rate which is a multiple of the local receiver clock frequency by passing the data signal through a multitap delay line. The delay line outputs are supplied to a register, and the register output which yields the lowest bit error rate is determined and used as the data sampling point. The optimum sampling point is determined by first ascertaining a nominal sampling point from the signal preamble and then programmatically incrementing through the available sampling points (register outputs) until there is no improvement in bit error rate. <IMAGE>

Title: Method of generating data for pcb assembly mounters
Inventor: JYOKO NOBUHIRO
IPC: B23P21/00
Filed: 1992-06-25
Abstract: An assembly line for e.g. hybrid circuit boards is constructed of a plurality of multi-function machines which can mount various types of parts or, for each type of part to be mounted, a plurality of dedicated machines of the same type. Assembly time is minimised by extracting data, in process 10, from parts mounting information which is different for each printed circuit board. The total assembly, the so-called "tact" time of each automatic machine, which depends on the type and the number of parts to be mounted, is calculated in the load calculation process 20. Assembly tasks are transferred from an automatic machine having a large load to an automatic machine having a small load to equalize the mounting "tact" time of each automatic machine, in the alteration process 30. When the machine loads have been thus equalised. NC data for each automatic machine is automatically generated in the decision process 40. <IMAGE>

Title: Optical beam smoke sensor
Inventor: APPLEBY DAVID
IPC: G08B17/103
Filed: 1992-08-11
Abstract: A sensor which comprises emitters 2a to 2g which can emit narrow beams of infra-red light via optical elements 3a to 3g, each beam being angled in a different direction. Each emitter may be driven individually via electronic means 4a to 4g under the control of a microcomputer 5, such as to control the direction and the energy of the beam. Light receivers 8 and optical elements 9 have a field of view which includes the total emission field. For any combination of emitters selected the quantity of light received may be analysed. Used in a singlepath optical beam smoke sensor, control of the beam permits a reflective target to be imaged and the sensor to be automatically aligned, improving the performance and reliability. The sensor may also be used without a target by utilising reflections from the walls of the room in which it is installed, or by utilising an auxiliary receiver/emitter unit which detects the pulses of light and emits a return pulse after a short time delay. <IMAGE>

Title: Radio-based hearing aid system
Inventor: HALL ANDREW JAMES JAMIESON
IPC: H04R25/00
Filed: 1993-06-21
Abstract: One embodiment provides a personal radio-based hearing aid system which interfaces with existing hearing aids using the "T" facility (28). The system comprises switchable unidirectional or omnidirectional microphone (18); a line input (22); an FM radio transmitter (31). The components are housed in a discrete hand-held unit (17) with integral stand (21), and an FM receiver unit (23) connected to an inductive loop (27) to form a discrete pendant and necklace. The prime use of said system is to give the user greater control over his environment by using the system to compensate for the loss of natural aural focus. The system addresses the problems of a "background noise", by capturing the desired sounds by selection. The captured sound is superior to that captured by existing hearing aids which, although incorporating complex audio processing circuitry, have not been capable of distinguishing between desired and undesired sounds. Furthermore the system is cheaper than existing systems.

IPC: G09F21/04
Filed: 1993-10-08
Abstract: In a London taxi, a passenger compartment includes two seats for occasional use when more than two passengers are to be carried. The occasional seats are arranged to tip up when not required and the seat undersides can thus carry a display panel located to confront a passenger on the taxi rear seat. The panel may carry advertisement material. The invention provides a seat underside display unit comprising a seat underside frame (11), a light box (14) including a panel (16) for supporting display material, the light box (14) being fixed relative to the frame (11), and a seat pad (13) located on the underside frame. This gives a light source for the display panel so the display remains effective for both day and night time operation. The frame (11) may carry hinge means by which the unit may be mounted on a support. The hinge means may include a hinge pin of hollow construction to accommodate wiring, connecting the light box to an electrical power supply. The light box may be activated by switches in passenger and or driver compartment, by simultaneous activation of side lights or by incorporation of an attitude-sensitive switch in the tip-up seat. <IMAGE>

Title: High resolution laser beam scanner and method for operation thereof
Inventor: KHATTAK ANWAR S
IPC: G02B26/10
Filed: 1993-03-09
Abstract: A laser beam scanner in its preferred form has a laser source (62) which emits a laser beam (70) at a prism (76). The prism receives and deflects the laser beam toward a spherical lens (66), which receives the laser beam and converges it. A spherical reflector (68) then redirects and focuses the converging laser beam to a laser scan spot (82) along a scan line (83). The laser beam scanner may include one or multiple prisms, wherein individual prisms may be single or multi-faceted prisms (142, 144). The laser beam scanner effectively eliminates across-scan error and generates a mathematically perfect scan line. The scanner has a high optical efficiency and a very short retrace time or blackout time. A method for laser scanning using a prism, spherical lens, and spherical reflector is also disclosed. <IMAGE>
