Title: Apparatus for and method of simulating ocular optical system
Inventor: QI HUA
IPC: G06F19/00
Filed: 1996-03-22
Granted: 1999-01-26
Abstract: An apparatus for simulating an ocular optical system simulates a retinal image produced by a human eye through an optical lens. Optical system data are produced from an optical system including a cornea, a pupil, an intraocular lens, a retina, etc. Based on the optical system data, point spread functions each indicative of a distribution on an image plane of light emitted from a certain point are calculated by PSF (Point Spread Function) calculating means. Image data are subjected to convolutional integration with the point spread functions, determining retinal image data. The retinal image data are converted into display data, which are supplied to a display unit to display a retinal image thereon. The retinal image displayed on the display unit is an image that would be actually formed on the retina of the human eye, and provides an accurate objective indication of how the image is seen by the patient.

Title: Recepteur a conversion directe
Inventor: SMITH CHRISTOPHER NIGEL
IPC: H04L27/14

Granted: 2001-07-24
Abstract: Le récepteur de la présente invention comporte un dispositif d'entrée composé d'une antenne et d'un filtre d'arrêt dont la sortie est connectée à un amplificateur. Le signal d'entrée est divisé et mélangé avec un signal en phase et en quadrature généré par un oscillateur dans un circuit de mélange, respectivement. Une sortie de chaque circuit de mélange est appliquée à un filtre passe-bas et à une entrée d'un circuit limiteur. La sortie de chaque filtre passe-bas est appliquée à une entrée d'un circuit sommateur, respectivement, dont le premier est conçu pour additionner les signaux en phase et en quadrature et le second est conçu pour soustraire les signaux en phase et en quadrature afin de générer un signal de sortie respectif ayant un axe intermédiaire entre les axes des signaux en phase et en quadrature. Ces signaux, ainsi que les signaux en phase et en quadrature, sont passés à travers un circuit limiteur respectivement et acheminés vers un circuit décodeur en vue de la récupération des données. La sortie des circuits limiteurs représente des signaux quantifiés à huit états de phase possibles séparés de 45~. Lorsque le signal d'entrée est modulé par déplacement de fréquence gaussien, le vecteur coupe toujours au moins un axe, si bien que la direction de rotation peut être établie avant la récupération des données. Dans un autre mode de réalisation, un combineur quotientométrique peut être utilisé au lieu des circuits sommateurs, et cela est particulièrement utile pour la modulation différentielle par déplacement de phase en quadrature .pi./4 dans laquelle l'exécution de phase par symbole est de ~ 45~ ou ~ 135~ selon la combinaison de paires de bits et dans ce mode de réalisation, un minimum de huit axes sont générés, produisant seize secteurs et une résolution de phase de 22,5~.

Abstract: A vehicle computer system has a housing sized to be mounted in a vehicle dashboard or other appropriate location, a computer mounted within the housing, and an open platform operating system which executes on an open hardware architecture computer. The open platform operating system supports multiple different applications that can be supplied by a vehicle user. For instance, the operating system can support applications pertaining io entertainment, navigation, communications, security, diagnostics, and others. The computer has one or more storage drive (e.g., CD drive, sloppy disk drive, cassette player, or hard disk drive) which permits the vehicle user to download programs from a storage medium (e.g., CD, diskette, cassette, or hard disk) to the computer. In the described implementation, the computer has two independent processors. One processor, which runs the operating system, is mounted in a stationary base unit of the housing and the other processor is mounted to a faceplate which is detachable from the base unit. When the faceplate is attached, the first processor provides the primacy control over all operating systems (i.e., entertainment, navigation, communications, security, diagnostics, and others) and the faceplate processor is subservient. When the faceplate is detached, it forms a portable RF device with the faceplate processor providing radio and communications capabilities.

Abstract: Système pour sensiblement éliminer la distorsion non linéaire, telle que les produits d'intermodulation, introduite lorsqu'un signal est traité par un dispositif non linéaire (106). Le système ajoute un signal hors bande (111) à un signal d'entrée (101) pour produire un signal combiné (105) ayant une puissance sensiblement égale à la puissance du point de fonctionnement nominal pour un dispositif non linéaire (106). De préférence, la puissance instantanée du signal hors bande (111) est ajustée par un amplificateur de gain automatique (120). Le signal combiné (105) est envoyé au dispositif non linéaire (106) de sorte qu'une sortie soit produite. Un filtre (108) traite la sortie du dispositif non linéaire (106) pour récupérer la teneur en information du signal d'origine (101) après traitement par le dispositif non linéaire (106). Par exemple, si le dispositif non linéaire (106) est un amplificateur de puissance, la sortie (109) après filtrage est une amplification du signal d'entrée (101).

Abstract: This invention provides a process for polymerizing a vinyl chloride monomer wherein the vinyl chloride monomer is subject to homopolymerization or (co)polymerization with a monomer copolymerizable with the vinyl chloride monomer in an aqueous solvent, comprising applying in advance a coating liquid containing a cocondensation product obtained by reacting either a phenothiazine derivative and an aldehyde or a phenothiazine derivative, a naphthol derivative and an aldehyde to give an initial condensation product and then reacting the initial product with a polyphenol, to an inner wall of a polymerization tank and parts of an apparatus in contact with the monomers during the polymerization process.  The process of this invention makes it possible to apply the cocondensation product as an aqueous solution to, e.g., an inner wall of a polymerization tank; to quite effectively prevent polymer adhesion in, e.g., a polymerization tank, without affecting a polymerization rate or physical properties of the product; and thus to eliminate the need for removing adhered polymer after every polymerization process and to realize closed polymerization in which a manhole should not be opened for every polymerization process.

Abstract: A vehicle-installed supporting seat for a passenger (28) is provided, which includes a seat back (12) provided with an integral head-neck restraint (14) comprising a cranium support portion (16) and a cervical spine support portion (18). Each portion includes a layer of resilient material (20) supported on an underlying inflexible support shell (22), which together act to effectively define a contour (24) that interfits with the posterior contour (26) of the passenger's cranium and cervical spine.

Title: Rail vision system
Inventor: KULL ROBERT C
IPC: B61L3/06
Filed: 1998-01-07
Granted: 2000-09-19
Abstract: A rail vision system visually reads signal aspect information from each wayside signal device of a wayside signaling system.          It also warn a train operator of the more restrictive signal aspects and imposes a penalty brake application should the train operator fail to acknowledge the warning.  Each wayside signal device communicates from a railway operating authority information including directions as to how the train should proceed along the upcoming segment of railway track.  The rail vision system includes a signal locating system and a rail navigation  system.    The  signal  locating  system  isolates visually the upcoming wayside signal device and reads the information therefrom as the train approaches thereto.   The rail navigation system determines the position that the train occupies on the railway track and provides the signal locating system with data as to the whereabouts of the upcoming wayside signal device relative to the position of the train.   This enables the signal locating system to isolate visually the upcoming wayside signal device and to provide the information read therefrom to  the  rail  navigation  system.   The  rail navigation system can then warn the train operator of the more restrictive signal aspects, and should the train operator fail to acknowledge the warning, impose a penalty brake application.
