Title: Photographic Printing Apparatus
Inventor: IWASAKI RYUICHI
IPC: G03B27/72
Filed: 1994-06-06
Abstract: A photographic printing apparatus includes a reading device for reading image information from a film, and an exposure condition computing device for computing exposure conditions for exposing a photosensitive material based on the image information read by the reading device. The apparatus further includes an image information converter for converting the image information read by the reading device into image information expected to appear on the photosensitive material when the photosensitive material is exposed to the image information on the film under the exposure conditions computed by the exposure condition computing device. The image information converted by the image information converter is displayed on a monitor. The exposure condition computing device receives instructions through a control panel to correct the exposure conditions for the image information displayed on the monitor, car instructions not to correct the exposure conditions. An exposure device exposes the photosensitive material under exposure condition computed by the exposure condition computing device based on correcting instructions inputted through the control panel. The exposure device is operable in parallel with an input from the control panel to the exposure condition computing device, to exposure the photosensitive material to image information for which the exposure conditions have been corrected based on the correcting instructions from the control panel or for which non-correction instructions have been received.

Title: Video display system with digital de-interlacing
Inventor: GOVE ROBERT J
IPC: H04N7/01
Filed: 1994-12-22
Abstract: A line generator (31) for receiving fields of pixel data sampled from a video input signal and for generating additional lines of pixel data so that the display frames will have more lines than the fields. The line generator (31) has a motion detector (31a) that determines, on a pixel by pixel basis, whether some part of the current field is in motion. A motion signal from the motion detector (31a) is used to select between outputs of two or more pixel generators (31b, 31c). One of the pixel generators (31b) provides pixel values that are better suited for display when the image is not in motion. The other pixel generator (31c) provides pixel values that are better suited for display when the image is in motion.

Dans un exemple de méthode de traitement d'un signal qui inclut les étapes consistant à appliquer un processus de codage à étalement de spectre, y compris le codage d'un premier segment du signal à l'aide d'un premier codeur de canal fonctionnant à un premier débit afin de générer un premier segment de codage avec des bits plus importants par le biais d'un premier processus de protection contre les erreurs. L'étape suivante consiste à coder un deuxième segment du signal à l'aide d'un deuxième codeur de canal fonctionnant à un deuxième débit afin de générer un deuxième segment codé avec des bits moins importants par le biais d'un deuxième processus de protection contre les erreurs. Le deuxième débit est différent du premier débit et le premier processus de protection contre les erreurs fournit un meilleur niveau de protection contre les erreurs que le deuxième processus de protection contre les erreurs.

Inventor: SMITH DAVID B
IPC: H04M15/00
Filed: 1995-07-25
Abstract: A limit is placed on charges to be incurred on a telecommunications call. Normally, this limit is specified by the caller. The telecommunications network maintains a running tally of the charges being incurred and notifies thecaller when the charges approach the limit. At that time, the caller may specify a new limit, simply disconnect, or be automatically disconnected when the limit isreached. Advantageously, callers can limit the charges on a particular call without having to be aware of the exact charging parameters for that call.

Title: Elliptic curve encryption systems
Inventor: AGNEW GORDON B
IPC: G06F7/72
Filed: 1995-07-31
Abstract: An elliptic curve encryption system represents coordinates of a point on the curve as a vector of binary digits in a normal basis representation in F2m. A key is generated from multiple additions of one or more points in a finite field. Inverses of values are computed using a finite field multiplier and successive exponentiations. A key is represented as the coordinates of a point on the curve and key transfer may be accomplished with the transmission of only one coordinate and identifying information of the second. An encryption protocol using one of the coordinates and a further function of that coordinate is also described.

Title: Method and apparatus for precipitation detection and differentiation
Inventor: INENAGA ANDREW S
IPC: G01W1/14
Filed: 1995-08-24
Abstract: A direct backscatter technique provides for the detection of precipitation in a measuring volume.  A source light beam is projected into the measuring volume. Light in the volume, including source light scattered from any precipitation within the volume, is collected and detected. A signal is generated corresponding to the detected light.  This signal is used to determine whether precipitation is present in the measuring volume. The light scattered from precipitation within the measuring volume may also be used to differentiate between types of particles.  Rain and snow, for example, can be differentiated based on whether the transmitted light changed from its original polarization state.

IPC: E06B7/23
Filed: 1996-01-17
Abstract: A mobile partition wall includes several wall elements (1, 1') that are each suspended from a track (2) secured to the ceiling of a room.  Each wall element is provided with coupling valves (30, 32) which pneumatically interconnect the wall elements to allow the continuous throughflow of compressed air.   The com-pressed air actuates pneumatic stroke devices to press respective seal bars (8, 9) against the ceiling and the floor in order to achieve good noise insulation and stability of the wall elements. The terminal wall element (1') includes a laterally extendable sliding termination panel (70) that is connected to a pneumatic drive device for extending the termination panel from the wall element (1').  In this manner, any vertical gap remaining between the terminal wall element and a wall of the room can be simply close and sealed by the termination panel.  Pneumatic valves are arranged to control the pressurization sequence of the pneumatic elements.  An extension limit valve is actuated when the termina-tion panel is extended against the room wall, and only then is the compressed air directed to the pneumatic stroke devices for extending the seal bars.
