Title: Leg exercising apparatus
IPC: A63B21/00
Filed: 2001-01-26
Abstract: Leg exercising apparatus (100) is formed from a first, substantially pear-shaped sheet (110) being bonded face-to-face with a second substantially pear-shaped sheet, around the periphery of each. The two sheets (110) are also bonded to one another along a line of symmetry of each pear-shaped sheet (110) so as to create two air-tight chambers joined to one another by a restriction. The apparatus (100) is inflatable by way of a valve (130). Each chamber is arranged to receive a respective foot of an operator and arranged to be deflated under action of the respective foot to pass air, via the restriction, to the respective other chamber. Each chamber, when inflated is substantially wedge-shaped, a narrow end of each chamber corresponding to a heel-receiving portion of that chamber. Thus, movement of each foot during operation is angular movement pivoting about the respective heel, the heel remaining on a surface on which the apparatus (100) is positioned.
Patent GB-0214545-D0 (GB)
Title: Fluid analysis
IPC: G01N21/05
Filed: 2002-06-24
Abstract: Fluid analysis may be achieved according to embodiments of the present invention by introducing a water-based analyte into a hollow core region (1000) of a photonic crystal waveguide, for example a photonic crystal fibre, acting as a liquid core waveguide. The waveguide has, around the core region, a microstructured cladding region (1020), which comprises a silica matrix (1060) filled with a periodic array of air holes (1040). The waveguide is able to guide a wide range of wavelengths of light, including excitation and sensing wavelengths of light, through the analyte by total internal reflection in the core region. This is possible because the cladding region of a photonic crystal waveguide can be arranged to have an effective refractive index lower than water, even though silica has a refractive index higher than water. Many other analytes, with even lower refractive indices than water, may be tested according to other embodiments of the present invention.

Title: Composite structure
IPC: B29D99/00
Filed: 2007-04-30
Abstract: A composite structure which may form, for example, the skin of an aircraft wing or fuselage comprises a panel (20) and a series of stringers (21-23) bonded to the surface of the panel (20). Each stringer comprises a web (24) extending at right angles to the panel (20) and a pair of flanges (25, 26) which are coplanar with the panel. The web (24) is tapered at the run-out in order to facilitate load transfer from the skin to the stringer, by providing a gradual increase in transverse bending and axial stiffness and relieving local stress concentrations. XA pad (27) protrudes downwardly from the base of the stringer (22) and extends beyond the ends of the web (24) and flanges (25, 26). The pad (27) is embedded in a recess in the panel. The recess has a right-hand end wall (30) and a left-hand end wall (31). The walls (30, 31) are oriented in substantially opposite directions, and extend across the width of the stringer substantially at right angles to its length. The end wall (30) engages a right-hand end surface (32) of the pad (27), and the end wall (31) engages a left-hand end surface (33) of the pad (27).

Title: Improvements in and relating to engine monitoring
Filed: 2007-06-01
Abstract: A method and device for creating an accurate simulation or model of the performance of a vehicle or an internal combustion engine in accordance with the invention comprises accessing the engine on-board diagnostic port (OBD), reading data from the desired industry standard parameter indicators (PID), using these data to produce a basic simulation of the engine operating characteristics, accessing and reading non-industry standard PIDs and using the output from the basic simulation in order to identify the non-industry standard PIDs with a high degree of certainty. As it may not be possible to identify some or all of the required non-industry standard PIDs or their scale due to timing delays or coding, an additional feature of the invention is to prompt a driver of a vehicle to drive the vehicle in a certain way or to perform a certain operation of the engine in order to trigger an event which will assist in identifying the missing non-industry standard PID(s) or will increase the degree of correlation or certainty in identifying the function or the scale of the said non-industry standard PID.

Title: Heat transfer apparatus
IPC: F28F3/10
Filed: 1983-08-23
Abstract: A heat transfer plate for heat transfer apparatus, such as heat exchangers or evaporators is disclosed which is at least partially bounded by a groove (32) for receiving a gasket for general conformity therewith and to seal against an adjacent plate, wherein; the groove comprises an inner side wall and an outer side wall; the outer side wall of the groove is provided with a number of lateral bays (30), the gasket being formed with a number of corresponding spaced projections engaging in and matching with said bays; the base (33) of each bay is at a level other than the base (34) of the groove, and; each bay (30) does not communicate with the ambient thereby limiting movement of the gasket material along each said bay.   The embodiments of the invention have a common feature that the gasket sealingly engages the rear wall (27). This engagement limits extrusion of the gasket material along the bay of the groove and thereby prevents <<blowing-out>> of the gasket at these points. Furthermore the floor of the bay, (40) is at a level other than the floor of the groove (42). This difference in level aids engagement between the gasket and the heat-transfer plate.

Title: Image enhancement method and circuit using quantized mean-matching histogram equalization
IPC: H04N19/136
Filed: 1997-08-14
Abstract: An image enhancement circuit and a method therefor including the steps of quantizing the level of an input image signal, obtaining a cumulative density function on the basis of a gray level distribution of a screen unit with respect to the quantized image signal, outputting a cumulative density function value interpolated on the basis of the quantized cumulative density function value, calculating the mean level of the input image signal in a screen unit, and controlling a transform function to map the input image signal to a gray level and map the mean level to itself, by using the interpolated cumulative density function as the transform function. In addition, the image enhancement method includes the steps of outputting a compensated mean level by adding a corrected value depending on a predetermined correction function to the mean level, and controlling the interpolated cumulative density function as a transform function to map an input image signal to a new gray level on the basis of the interpolated cumulative density function value and to map the mean level to the compensated mean level. Thus, contrast is enhanced, and the mean brightness of a given image is continuously maintained.

Abstract: A mop squeezer (104) is carried by a wheel-mounted frame (102). The squeezer comprises a squeezing surface (2) and at least one squeezing head (10,11) carried on a pivot bar (6). Downward movement of an operating linkage (31) rotates a pivoted plate (27) within the squeezer (104) which acts via a link (33) to rotate the pivot bar (6) thereby causing the squeezing head (10,11) to move towards the fixed squeezing surface (2).

Filed: 1997-11-20
Abstract: A coordinate positioning machine has an operating module such as a tool or probe (10) mounted for translational motion relative to a table (16) with three degrees of freedom by means of three articulated linkages (18). Each of the linkages is made up of a torsion box (22) which is pivotally mounted to a vertical pillar (20) with one degree of freedom, and a pair of struts (26), each of which is pivotally mounted with two degrees of freedom to the torsion box at one end, and to the operating module at the other. The linkages cooperate to prevent all rotational motion of the operating module, while allowing translation. Motion of the operating module is actuated manually, and the mass thereof is counterbalanced by an articulated counterbalance arm (90) which guides a cable (96) that is in turn connected to a fusee. Displacement of the operating module is measured using scale and readhead encoders (40,50). Motion of the operating module can be restricted to a single plane by means of locking devices (132) operating between the struts (26), thereby to enable scanning of a surface in a series of parallel planes.
