Patent EP-0594183-A1 (EP)
Inventor: GRIFFIN ROBERT M
IPC: H01K1/24
Filed: 1993-10-21
Abstract: A self-supporting/self-centering filament for a double-ended lamp envelope includes two inlead portions, an active center segment, two inactive end segments and two skip turns. The two end segments are attached to the inlead portions and contact an inner surface of the lamp envelope so that the filament is supported and centered within the lamp envelope. The two skip turns interconnect the end segments and the center segment. The end segments, the center segment and the skip turns have a coiled coil configuration and have a common central axis. The filament is particularly useful in a tubular incandescent lamp capsule having an infrared reflective coating on its outer surface as the filament exhibits excellent self-supporting and self-centering characteristics.

IPC: H04B7/212

Abstract: A multiple channel demand assignment multiple access (DAMA) system is configured as a spoke-and-hub star network in which a satellite relays information between each of many small-aperture terminals (SATs), which may be portable terminals (PTs), and a hub network control terminal (NCT) which receives requests from the PTs, allocates channel resources, and broadcasts housekeeping messages. The system has a reservation protocol using at least three separate data channels to take advantage of the inherent lack of adequate radiated power at the PTs: a NCT outbound channel is tightly packed with data, without guard spaces, and it uses typically 98% of the allocated power; separate return channels for data and reservations use little satellite power, with no need for extremely tight data packing. Guard spaces are included in the reservation channel to overcome the total range of propagation delay uncertainty without requiring knowledge of the location of a particular PT.

Abstract: A vertical cavity of a rectangular shape having short and long sides (a,b) is defined between first and second mirror layers (2,4). Thus, two resonant wavelengths are obtained in a vertical-to-surface optical semiconductor device having the vertical cavity. The resonant wavelengths (950.0nm, 950.4nm) are shifted in an increasing wavelength direction due to the heat generated in operation of the optical semiconductor device to shifted wavelengths (950.4nm, 950.8nm). Light of the shifted short wavelength (950.4nm) emitted from the first optical semiconductor device has its plane of polarization rotated by 90°, and is then received by the second optical semiconductor device as light of the non-shifted long wavelength .

Filed: 1993-09-24
Abstract: The present method describes precise temperature measurement with two-wavelength pyrometers on bodies in which the environmental radiation is neglible by comparison with the infrared radiation of the measurement material. The method is particularly suitable for pyrometric temperature measurement of materials having variable surface characteristics and having a very low emittance, in particular a wavelength-dependent emittance. In this case, the surface temperature of the measurement material is detected using a two-wavelength pyrometer and determined by a correlation analysis of the functional relationship between the two emittances. The parameters of the functional relationship are determined by reference temperature measurements. The temperature determination of the measurement material is then performed by solving a system of nonlinear equations which contains the functional relationship between the two emittances and the Planck equations for real emitters which are valid for the two measurement wavelengths. <IMAGE>

Abstract: An exhalation valve (14) for a filtering face mask (10) has a flexible flap (24) that makes contact with a curved seal ridge (30) of a valve seat (26) when the valve (14) is in the closed position. The curvature of the seal ridge (30) corresponds to a deformation curve exhibited by the flexible flap (24) when secured as a cantilever at one end and exposed at its free portion to a uniform force and/or a force of at least the weight of the free portion of the flexible flap. A seal ridge curvature corresponding to a flexible flap exposed to uniform force allows the flexible flap (24) to exert a generally uniform pressure on the seal ridge to provide a good seal. A seal ridge curvature corresponding to a flexible flap exposed to a force of at least the weight of the flap's free portion allows the flexible flap (24) to be held in an abutting relationship to the seal ridge (30) under any static orientation by a minimum amount of force, thereby providing a face mask (10) with an extraordinary low pressure drop during an exhalation.
