Title: Hollow solder structure and its method of manufacture
Inventor: KIM SANG-YOUNG
IPC: B23K35/14
Filed: 2002-05-31
Abstract: A solder structure comprising a radially-curved exterior surface 26 enclosing a predetermined-sized cavity 28 is used for flexibly joining together at predetermined conductive contact points 30,32 two planar elements 14,18 having dissimilar properties. By assembling the two planar elements 14,18 in a tiered arrangement, with one planar element 14 having an annular conductive pad 30 and the other planar element 18 having either a corresponding annular or circular conductive pad 32 separated by a spherical solder compound, the compound comprising solder and a fluxing agent, a hollow solder structure can be created during a melting and subsequent cooling of the solder compound. The plasticity/resiliency characteristics of the resulting hollow solder structure absorbs lateral movement of the two planar elements relative to each other without degradation of the solder joint. The solder structure may be spherical or cylindrical.

Filed: 2001-10-25
Abstract: A fluorescent lamp circuit has fluorescent lamps U10, U11 a transformer TF and ballast capacitors C1, C2 located not more than one quarter of the length of the lamp away from the lamps, thus enabling good matching of currents through the lamps U10, U11. The circuit also has regulator SR, the primary circuit of the transformer TF, electronic switches TR2A, TR2B and current sensing device Rsense connected successively in series across power supply PSF. Controller CTRL is connected to create a feed back loop. The secondary circuit of the transformer TF is coupled to fluorescent lamps U10, U11 via the ballast capacitors C1, C2. Diode D1 creates unidirectional current flow so current sensing device Rsense indicates only energy input to lamps U10, U11. Pulse width modulator PM with predetermined input is connected to regulator SR, and via delay circuit TD to controller CTRL, thus permitting a larger dimming ratio, and further control of input power. Overvoltage detector OVD is connected to sense the voltage across inductor L3 and transformer TF giving further control in the event of excess voltage.

IPC: F15B21/14
Filed: 2002-04-25
Abstract: A hydraulic system (10) controls the flow of fluid to and from several functions (12; 14) on a machine. Each function has a valve assembly (21, 22, 23, 24; 31, 32, 33, 34) through which fluid is supplied under pressure from a source (20) to an actuator (16, 36) and through which fluid returns form the actuator to a shared return line (28) connected by a return line metering valve (46) to the system tank (48). There are several regeneration mode of operation in which fluid exhausted from one port is supplied into the other port of the same actuator, which eliminates or reduces the amount of hydraulic fluid that must be supplied from the source. In some regeneration modes, input fluid for an actuator is obtained from another hydraulic function via the shared return line. In these regeneration modes an electronic controller (44) operates the return line metering valve (46) to restrict fluid from flowing into the tank (48) from the shared return line (28), so that the fluid will be available to be supplied into an actuator port.

Title: Wireless telecommunications
Inventor: CARTER PHILLIP
IPC: H04W4/00
Filed: 2004-02-24
Abstract: A cellular telephony system is described, having possibly overlapping 3G and 2G service areas together with 3G and 2G handsets having inter-operability at least as far as voice calls are concerned. At least some of the 3G handsets have voice telephony (VT) capability so that each of these handsets is able to communicate with another similarly equipped 3G handset when in a 3G service area - though not able to communicate with a similarly equipped 3G handset when it is off or unreachable in a 3G service area or when in a 2G service area - and not able at all to make VT communication with a 2G handset. The system provides a VT mailbox 9 for receiving, storing and forwarding a VT call when addressed to a 3G handset with VT capability but not currently able to receive the VT call (because it is switched off or unreachable in a 3G service area or is in a 2G service area). If the VT call is directed to a handset not having VT capability, the system automatically invites 11 the caller to leave a message for forwarding to the called handset, which may be a voice message or may be a video message based on the VT call and sent as an MMS message or possibly as an emailed link.

Title: Sheet feeding device with automatic thickness set-up
Inventor: HOWARD DONALD ANTHONY
IPC: G01B7/06
Filed: 2004-04-02
Abstract: A product feeding device A (e.g. to feed items of mail) measures the thickness of an item C passing between the device and a roller B or plate (figure 2), in order to prevent two items being fed instead of one. A potentiometer detects the thickness via the linear displacement of a sensor tip due to deflection of a wheel on the device as an item passes between the wheel and the roller. The device learns the average thickness of the product to be fed from the measurements taken. An alarm is raised if the fed thickness is greater or less than the self-taught average thickness, or if no item is fed at all. The device is set up automatically and needs no operator intervention to set the item thickness.

Title: The Copy Protection Of Optical Disks
Inventor: BASILE CARMEN LAURA
IPC: G11B20/00
Filed: 2004-05-19
Abstract: Subversive DSV (SDSV) sequences of data symbols having a large absolute value of DSV are extremely valuable in the copy protection of optical discs as they can induce uncorrectable read errors. However, very few SDSV sequences of data symbols can be found in multimodal codes such as Eight-to-Sixteen Modulation (ESM), also referred to as Eight-to-Fourteen plus (EFM Plus), utilised in DVDs. It is required to select data symbols, for encoding using a multimodal code, which are capable of forcing an encoder to produce at least one subversive sequence of code words. A possible code word for a data symbol is selected if the code word has a large absolute value of DSV and there are no alternative code words, or all alternative code words are equivalent, or all alternatives except one are ruled out by RLL rules. The figure shows a sequence of data symbols D-1, D0 in states S-1, S0 which force an encoder to choose code words C-1 and C0 with a large absolute value of DSV. The selected data symbols are incorporated with user data for encoding to an optical disk in order to copy protect the optical disk.
