Title: Interrupt-driven keypad scanning method and apparatus.
Inventor: ZIMMERMAN DANIEL F
IPC: H03M11/20
Filed: 1997-11-19
Abstract: The interrupt-driven keypad scanning method and apparatus accurately interprets keypresses in single-keypress applications. Initially, interrupts (16, 26, 36, 46) associated with each column line (10, 20, 30, 40) of a keypad matrix (70) are set to trigger when a key is pressed. One an interrupt triggers, a microcontroller (99) polls the row liner (15, 25, 35, 45, 55, 65) to determine which key, if any, was validly pressed. If exactly one keypress is detected, the keypress is valid. Next, the interrupt for the valid key's column line is enabled while the other column line interrupts are disabled. When a next interrupt is received, the keypad returns to the row-scan state for determination of which keys are depressed. If no keys are depre-sed, which occurs when the validly-pressed key has been released, the keypad returns to the keypress-detect state. The method also interprets pathological keypresses such as key rollover, multiple keypresses, and key mis-hits.

Title: Roof and wall sandwich panel - formed by casting foam mixture on outer layer and pressing on metal profile
IPC: E04D3/35
Filed: 1981-07-02
Abstract: The outer layer of an isolating panel for building construction, to which pref. a profiled inner plate is attached, have between them a mass of foamed filling material, is to be regarded as the outer, finished, waterproof, non-metallic surface of the roof or wall. Down one long edge an overlapping strip projects and this is glued along the edge of the adjacent panel in the finished structure. The filling along the edge which is to come into contact with an adjacent panel is profiled obliquely to suit. The outer, waterproof layer is a mixture of bitumen and polypropylene with a reinforcement formed by non-woven polyester fibres. The profiled inner layer is a steel plate. The filling is a polyurethane foam and at one side the profiled plate projects beyond it. This facilitates the making of the joint and in particular with a roof, sagging is prevented when it is walked on so that the filling is not easily broken up.
