Title: Improved condylar platen and pad construction
Inventor: YOUNG DAVID ERNEST
IPC: A61F5/01
Filed: 1995-09-04
Abstract: The construction, which may be used with most types of orthopaedic and orthotic hinge, integrates by moulding a hinge backplate 16 with a joint pad platen 14 and shimming means 18. The platen has a flexible marginal portion 56 disposed about an extension 54 moulded peripherally to the enclosed hinge backplate, which portion may be contoured for conformability to a joint. The extension creates a recess between the flexible margin and the backplate. A joint pad is air- and foam-filled and a central portion thereof fits within said recess while a peripheral portion locates on the flexible margin. The condylar pad is covered overall by a bonnet. The construction eliminates drag between a platen and hinge arms and facilitates manufacture by reducing and combining parts.

Title: Cat-flap entry validation system
Inventor: HASLIP GRAHAM HAROLD
IPC: A01K11/00
Filed: 1996-09-17
Abstract: A cat-flap entry validation system fixed to the entrance of a cat-flap of the actuated flap-release mechanism variety, to inhibit the entry of a prey-carrying cat, is constructed from three pairs of energy beam transmitters 1 and associated receivers 2 mounted in a fixed plane and direction and angled to the horizontal and so positioned that the interruption of the central beam by the cat's pointed face prior to the interruption of either or both side beams allows the cat admission due to the resultant transmission of an actuating signal to the release mechanism; whilst interruption of either or both side beams by the cat's prey prior to the interruption of the central beam inhibits admission of the cat and prey due to the generation of signal that inhibits the transmission of the actuating signal to the release mechanism. The beams may be infrared or visible light, or ultrasonic or audible sound.

Title: Discriminating text from pictorial data by sensing paired edges and enhancing the text data before printing
Inventor: NOH JAE JUNG
IPC: B41J2/485
Filed: 1997-04-24
Abstract: Text 1K, DK is recognized in a scanned image by sensing left and right edges 123, 125, preferably in coincidence in all three color planes or otherwise to determine edges in black. Such edge sensing is preferably done by convolution of the input pixel stream with a windowed vertical jump (11, Fig 1) yielding narrow peaks 127, D27, 129, D29 of opposite directivity at beginning and end of each character stroke 1K, DK. Textual material is indicated where such peaks alternate in direction. Concurrent testing is desirable also for dark pixels 124, D24 between beginning and end of each stroke - and light pixels 122, 126, D22, D26 between end of one stroke and beginning of the next. In addition it is preferable to test for an appropriate (black and white) mix of pixels in each candidate text region. A preliminary test is conducted to determine whether a region being scanned is pictorial; in this case the entire edge-detection protocol with associated tests is bypassed on the operating assumption that black-and-white text 1K, DK cannot be present in a region PG etc., 770-850 that is pictorial. The pictorial-region test consists of determining whether only very few light pixels are present.
