Title: Method of Soft Handoff in a Mobile Radio Communication System
Inventor: TANOUE KATSUMI
IPC: H04W36/08
Filed: 1996-05-16
Abstract: When the reception electric field from a radio base station 40 weakens beyond a preset level during communication, the mobile station 80 receives a TDMA frame of reception electric fields intermittently from other radio base stations 41-50 during communication with the radio base station 40, and selects a radio base station 41 to be switched to based on the reception electric field which is the strongest. The mobile station 80 then performs intermittent operations the same for preparing channel re-connection with the radio base station 41 while continuing the communication with the radio base station 40, and then, terminates the communication with the radio base station 40 and commences the communication with the radio base station 41 when the preparation operations for channel re-connection have been completed. The disconnection time for the handoff is thereby reduced.

Title: Video presentation system
Inventor: FURUSAWA TOYOAKI
IPC: G06F3/048
Filed: 1996-08-12
Abstract: A video presentation system is provided which permits a process in which, when an object in motion video image is handled, an action relating to the object is executed, without increasing load on a central processing unit or a memory. Subject-of-operation information, which defines objects to be handled by a user in relation to each of frames of video data at a transitional phase of time-varying motion of each object, is stored in video operation information retaining means, and when a user operation takes place, the frame position of a currently reproduced video image is acquired from video driving/processing means while screen coordinates of the object are acquired from a coordinates specifying device. Based on the acquired data, video operation information processing means searches the subject-of-operation information to identify the object handled by the user. The subject-of-operation information retains only information associated with each transitional phase of motion of the object, whereby the size of information can be reduced, thus permitting the object specifying process and a like process to be executed at high speed.

Title: Dinitrate esters
Inventor: COLCLOUGH MARTIN EAMON
IPC: C07F7/18
Filed: 1996-09-05
Abstract: A process for preparing 1,2- and 1,3-dinitrate esters (some of which are novel compounds) from polyols containing 1,2-or 1,3-diol fragments involves using an alkyl or aryl boronic acid to form a cyclic boronate ester derivative which is then reacted with dinitrogen pentoxide to directly generate the dinitrate ester. In the cyclic ester form the 1,2- or 1,3-hydroxyl groups are protected and other reactions may then be carried out on other parts of the molecule of which the fragment forms a part, leaving the dinitrate ester to be produced subsequently in the final step. High yields are obtained at both stages.

Title: Switched optical beam generator for imaging
Inventor: WHEELER JOSEPH A
IPC: G02B6/42
Filed: 1997-07-01
Abstract: A laser light source 12 is powered by a current greater than the lasing threshold (36, Figure 2) from source 26 to generate a coherent, single mode beam or by a current below the lasing threshold to generate an incoherent, multimode beam. The beam is input to a filter, for example a single mode optical fibre 16. When the beam is in the coherent, single mode state, it passes through the fibre with minimal attenuation whilst those modes of the incoherent, multimode beam which are not the single mode are attenuated by the fibre. The beam 22 in the coherent state has a power level which is sufficient to expose a substrate 24, whilst the component of the incoherent beam which is transmitted by the fibre has a power level which will not expose the substrate. The coherent and incoherent modes correspond respectively to "on" and "off" states of the imaging beam and can be switched more quickly than if the beam is switched off completely.

Title: Method for motion estimation in a moving picture
Inventor: PARK KYE-HO
IPC: H04N19/50
Filed: 1997-12-24
Abstract: A method for estimating the motion within a moving picture using a two-dimensional triangle-patch wireframe model, comprising the steps of dividing (200) the current frame of an input image signal into N 1 N 2  macroblock units, dividing (202) each of the macroblocks into two to create triangle patches, calculating (204) pixel differences between a reference block and search blocks of the previous frame in a predetermined range on the basis of the coordinate values of the respective apexes of the triangle patches, and calculating (206) a motion vector of the reference block of the current frame from the coordinate value of the matching block of the previous frame having a minimum pixel difference value among the calculated pixel differences. Thus, it is possible to obtain a picture of good quality compared with a picture reconstructed by the conventional BMA method for estimating the motion.

Patent GB-2319208-A (GB)
Title: Pipe joint
Inventor: KAYE ALAN
IPC: B29C65/56
Filed: 1996-07-17
Abstract: A method of making a pipe joint comprises providing a mould for forming substantially half the joint split longitudinally, moulding half the joint including strengthening webs, and assembling two halves so moulded to form the finished pipe joint. Moulding the joint in two complementary halves (12) enables strengthening webs (22) to be produced within the elbow, which is difficult or impossible with the conventional injection moulding technique. Since the webs can be designed to provide the strength where necessary, the thickness of the remainder of the elbow can be reduced, leading to an overall saving in weight and material. Moreover, by careful choice of the shape and positioning of the strengthening webs, a single mould is sufficient to produce both halves of the joint. By these means, savings of over 50 % on the cost of conventionally produced joints can be made.

Title: High conductivity buried layer in optical waveguide
Inventor: BOZEAT ROBERT JOHN
IPC: G02F1/025
Filed: 1998-02-24
Abstract: An optical device (300) comprises a multilayer structure, formed by wafer bonding, incorporating in sequence a silicon dioxide layer (304), a buried silicide layer (306), a contact layer (308) and a silicon surface layer (310). The surface layer (310) is selectively etched to form an exposed rib (312). An upper surface of the rib (312) is doped to form an elongate electrode (314) therealong. The surface layer (310) is selectively etched to the contact layer (308) in regions remote from the rib (312) to form via channels (316a, 316b) for making electrical connection to the contact layer (308). The rib (312) forms a waveguide along which radiation propagates. When the electrode (314) is biased relative to the contact layer (308), charge carriers are injected into the rib (312) and induce refractive index changes in a central, region (324) thereof where most of the radiation propagates along the rib (312). The silicide layer (306) provides an efficient current conduction path for injecting the carriers, thereby providing enhanced device operating bandwidth and reduced power dissipation.
