Inventor: TAKEMOTO TAKATOSHI
IPC: A63F7/02
Filed: 1991-09-17
Abstract: La présente invention est constituée par un appareil comportant une ligne de transmission de signaux repliée utilisée pour transmettre un courant générateur d'un champ magnétique, et d'une ligne de réception de signaux repliée qui est installée à un endroit tel qu'elle est couplée électromagnétiquement avec la ligne de transmission de signaux, et qui sert à détecter les variations d'induction magnétique causées par l'approche d'une pièce de métal. Les multiples lignes de transmission de signaux sont en montage coplanaire, ainsi que les multiples lignes de réception de signaux. Les plans des lignes de transmission de signaux et de réception de signaux sont maintenus parallèles, dans des directions perpendiculaires l'un avec l'autre, et forment par conséquent une matrice de détection. Celle-ci est montée en opposition avec un panneau le long duquel le corps métallique à détecter se déplace, la matrice et le panneau étant suffisamment espacés l'un de l'autre pour que le corps métallique puisse passer entre les deux. Des dispositifs de transmission et de réception de signaux sont connectés à la matrice de détection pour localiser le corps métallique.

Abstract: A public cordless telephone system includes an arrangement for informing a public handset unit when it is within the reception range of a public base unit even though all communication channels are then occupied or all public baseunits in the reception area are then busy communicating with other handset units. In operation, each public base unit while communicating with any public handset unit inserts in the communication channel it is then occupying spectrum energy such as is provided either by a pilot signal or a frequency shift keying (FSK) signal. By providing this additional spectrum energy along with normal voice signal energy in the communication channel, a public handset unit while searching for an available channel and interrogating this channel will be able to determine, even though the channel is occupied, that there is a public base unit within its reception range. If no available communication channel is found and a signal from one or more public base units is detected, the handset unit generates a first alerting signal for its user thereby informing the user of the one or more public base units in the area even though a telephone call may not be initiated due to all of the communication channels then being occupied. If an available communication channel is found, an attempt to establish communication with a public base unit is initiated by the handset unit over this available channel. If no response is received from a public base unit and if a signal from one or more public base units is detected, the handset unit generates a second alerting signal which thereby informs the user of the one or more public base units in the area even though a telephone call may not be initiated due to all of these public base units then being busy.

Title: Volumetric effects pixel processing
Inventor: SODERBERG BRIAN T
IPC: G06T15/50
Filed: 1992-08-06
Abstract: Abstract of the Disclosure In the real time image generation system disclosed herein, opaque or planal object pixels are defined by at least a color attribute and a depth value and volumetric pixels are defined by at least a color attribute, a depth value and an opacity gradient value.  A volumetric data buffer is provided for storing attributes and values associated with volumetric pixels  and the volumetric items are processed first to load that buffer.  Successive object pixel definitions are then read and the depth value of each current object pixel definition is compared with the depth value in the buffer and, a relative weight for the volumetric effect is calculated as a function of the relative depth values and the corresponding volume gradient value.  The color attributes of the object pixel and the volumetric data are then mixed as a function of the relative weighting to obtain a result color attribute which is output as the color for the respective pixel.

Title: Lock detector for switched reluctance machine rotor position estimator
Inventor: LYONS JAMES P
IPC: H02P25/08
Filed: 1992-08-13
Abstract: RD-20,393 LOCK DETECTOR FOR SWITCHED RELUCTANCE    MACHINE ROTOR POSITION ESTIMATOR        Abstract A lock detector for a switched reluctance motor (SRM) position estimator monitors the rotor angle estimates from a SRM rotor position estimator to make sure that the estimator is accurately tracking rotor position. Phase flux and current measurements corresponding to the rotor angle estimate of the sampled phase are supplied to dividing circuitry which generates a phase inductance estimate.  The phase inductance estimate is compared by logic circuitry to lower and upper inductance limits to determine whether the rotor angle estimate falls within a specified tolerance of a theoretical inductance value.  Alternatively, a flux-current map is used to generate a phase flux reference for comparison to the phase flux estimate.  A lock detector flip-flop is reset whenever the phase inductance estimate (or phase flux estimate) is outside the specified tolerance, and a signal is sent thereby to disable the SRM.

Title: Desensitizing anti-tartar dentifrice
Inventor: NORFLEET JAMES
IPC: A61K8/19
Filed: 1992-09-17
Abstract: An oral composition, such as a toothpaste, includes an anti-tartar proportion of a polyphosphate anti-tartar agent (preferably with synthetic anionic polymeric polycarboxylate or equivalent, and fluoride) and a desensitizing proportion of a tooth pain inhibiting potassium salt which passes through exposed dentin tubules to tooth nerves or neurons, which salt can be potassium nitrate, potassium citrate or potassium oxalate, so that it helps to prevent tartar from forming on the teeth and also lessens any pain experienced by persons contacting their sensitive teeth with the oral composition. Preferably the oral composition is a desensi-tizing anti-tartar toothpaste or gel which, when the teeth are brushed with it, aids in removal of at least some tartar and prevents its reappearance, and at the same time diminishes any tooth pain that the brusher would otherwise experience due to such brushing. In preferred toothpastes the anti-tartar agent and the desensitizing agent are both potassium compounds and other components of the toothpaste, such as the detergent or surfactant, thickener, water soluble fluoride, anionic polymeric polycarboxylate, sweetener and any anti-calculus agent present, when they may be present as salts, will also be potassium salts. In place of the mentioned anti-tartar agents there may be employed other anti-calculus compounds, such as AHP (azacycloheptane-2-2-diphosphonic acid) or corresponding alkali metal salt, preferably the potassium salt, and in such case it is very desirable for other components of the toothpaste to be in the forms of their potassium salts.

Title: Vascular stent
Inventor: FONTAINE ARTHUR B
IPC: A61F2/86
Filed: 1993-03-24
Abstract: Abstract of the Disclosure A vascular stent   (8)   for reducing hemodynamic disturbances caused by angioplasty.   In one aspect,  the stent is formed from a single,  continuous filament  (11) having a series of U-shaped bends (1-7'). The filament (11) is wrapped around a mandril (31), in a circular fashion, to align the curved portions of each bend (1-7') which are then connected.   In another aspect of the vascular stent, the filament is formed into a substantially tubular body (22) having a plurality of oblong, open cells which are staggered around the circumference of the tube.   When the body is formed in its unexpanded state, the long sides (14) of each oblong cell (39) are arranged substantially parallel to the longitudinal axis of the tubular body.   The filament is preferably bonded at the point of tangency between adjacent sides (34, 36 and 38, 40) of a cell (39).  When the body is expanded, the adjacent sides  (34,  36)  of each cell  (39) extend oblique to the longitudinal axis of the body.  In yet another aspect of the vascular stent, the single, continuous filament or wire is half-round  (i.e.,  semi-circular)  in transverse cross-section.  In a completed stent, the semi-circular wire profiles (25) are all on the exterior of the stent body while the planar portions (27) of the wire are all on the interior for providing a generally smooth interior surface. 39
