Patent GB-2314176-A (GB)
Title: Fluorescent lamps with current-mode driver control
Inventor: VITELLO ROBERT J
IPC: H05B41/392
Filed: 1997-06-13
Abstract: Light from a fluorescent lamp 230 is dimmed by modulating the width of current pulses. A current command signal is applied to a resonant bridge lamp driver 226 in response to a voltage-level corresponding to a given, selectable level of desired lamp brightness. The lamp driver operates as a flyback AC power source that advantageously uses a FET switch 222 to decouple the lamp and resonant bridge 226 from the current-sampling process. A resistor 232 only samples the current in an inductor 224 while the FET switch 222 is active. Because the current sample is decoupled from the lamp and bridge, particularly tight control of the regulation process is provided to control incoming noise and transients that affect the power supplied to the lamp, which may be used in a backit avionics display. The lamp driver can also operate as a synchronously driven resonant forward converter that senses the current actually supplied to the lamp and responds to changes in the lamp's condition (Fig Il).

Title: Digital receiver in which user is audibly informed on drop in signal quality
Inventor: RICHARDSON JULIAN HOWARD
IPC: H04M1/724
Filed: 1997-10-18
Abstract: In analog receivers hissing accompanies poor reception. In digital receivers no such forewarning of signal loss occurs and so some indication may be artificially provided. This application describes the use of audible tones whose number indicates the signal quality. The tones may be delivered at a convenient position in the speech signal.

Patent GB-2336494-A (GB)
Title: Digital filter
Inventor: RICHARDS DAVID CHARLES WILLIAM
IPC: H03H17/04
Filed: 1998-04-03
Abstract: A method of generating filter coefficients to provide a desired nth order filter response comprises adding one or more pole and zero pairs substantially collocated in the z-plane to form an (n+m)th order filter structure having the desired nth order filter response. (e.g. the third order structure shown has a second order response). A filter constructed in this way has an improved limit cycle behaviour compared with a conventional nth order filter. To further reduce limit cycle effects a dither signal may be added to input samples by a dither generator 300.

Title: Module for a space structure
Inventor: BAVEREL OLIVIER
IPC: E04B1/32
Filed: 1998-08-17
Abstract: A module (10) for a space structure (28) comprises three elongate members (12a, 12b, 12c), each member having a first free end (14a, 14b, 14c) and a second end (16a, 16b, 16c) connected at or adjacent said second end to one other of said members intermediate (18a, 18b, 18c) the ends of said one other member, thereby to form a triangle (26). The external angle formed at each junction between the members may be approximately 120 so that an approximately equilateral triangle (26) is formed. The preferred module is assembled with other similar modules to form a space structure of an equilateral hexagon grid. The grid may define a portion of the surface of a cone (figures 8b, 9b, 10b) and may be assembled with other such cones linked by structural joints formed by a plurality of modules of non-triangular polygonal, preferably parallelogram form. The interconnection of only two members at each joint (18a, 18b, 18c) enables simple joints to be used, in contrast to those used in for example geodesic structures where a large plurality of members may meet at each joint.

Title: Thin encapsulation process for making thin film read/write heads
Inventor: PAN WEI
IPC: C23C14/34
Filed: 1999-04-14
Abstract: Process for encapsulating a thin film recording head 10 in which a chamber 50 is provided in which a sputtering system deposits a encapsulation layer onto a fabricated stack of recording head components. The target 54 and the substrate 52 within the chamber are at different voltages relative to the chamber. Material is deposited from the target onto the stack 10 until there is a sufficient depth to cover the components of the stack. Then the relative bias voltage between the substrate and the chamber is increased over time whilst material continues to be deposited onto the stack. The higher bias voltage causes the layer to be deposited in a planar manner and also stress to the head is minimised because the voltage is gradually increased over a period of thirty minutes. Furthermore a process for creating bond pads on a thin film recording head is disclosed (Fig. 5A - 5F). In this process the encapsulation layer 92 is etched back in the vicinity of a stud 90 to form encapsulation side walls having an angle of less than 60 degrees from the horizontal and a metallic bond pad 100 is plated between these walls.
