Title: Method of video data broadcast in a sectorized cellular communication network
Inventor: GUO ZIHUA
IPC: H04W4/02
Filed: 2007-09-24
Abstract: Allocations of frequencies and timeslots for broadcasts in sectors controlled by a plurality of base stations are included in control information transmitted to the base stations from a central node, thereby realising video broadcast and data communication in the cellular network while avoiding a reduced efficiency of use of frequency spectrum during video broadcasting due to sectorization.

Title: MIMO decoder with QR decomposition performed before and after lattice reduction, using a feedback arrangement
Inventor: LILLIE ANDREW GEORGE
IPC: H04L1/06
Filed: 2007-10-18
Abstract: A lattice reduction aided MIMO detector is disclosed which is operable to detect information in a packet based signal comprising a header and one or more data symbols. The detector comprises a pre-processing section 12 operable to derive channel decoding information (<B>C</B>, <B>R</B>, <B>P</B>, <B>T</B> on the basis of a channel estimate <B>H</B> from said header, and a data processing section 14 operable to process said one or more data symbols with reference to said channel decoding information. The pre-processing section comprises QR decomposition means 24 and lattice reduction means 26, wherein an output from the lattice reduction means <B>HT</B> is fed back to the input of the QR decomposition means. Thus the QR decomposition means can be used as a first stage of lattice reduction to, for example, operate on the channel estimate input <B>H</B> to provide an upper triangular matrix <B>R</B> as input to the lattice reduction means. Crucially, the QR decomposition means can also operate on the reduced channel matrix <B>HT</B> to derive channel decoding information such as CORDIC information <B>C</B> based on QH . Fig. 4 is particularly relevant.

Title: Apparatus and methods for energy output prediction of renewable energy devices
Inventor: BOAIT PETER
IPC: F03B13/12
Filed: 2007-02-08
Abstract: The apparatus includes an electronic control unit 10 and an energy sensor 16. The energy sensor 16 measures an energy parameter that is affected by an energy output of the renewable energy device. The energy sensor 16 is a temperature sensor that measures the temperature of the water in a domestic hot water cylinder 2. Water is drawn out of the hot water cylinder 2 and heated by the solar panel 4 before being returned to the hot water cylinder 2. The energy sensor 16 provides energy data in the form of temperature measurements to the electronic control unit 10. The electronic control unit 10 uses this energy data to derive a profile of the changes over time in the energy parameter. It then correlates the derived profile with one or more reference profiles corresponding to a particular renewable energy source and uses the results of the correlation to determine a quantitative relationship between the reference profile and the energy output of the renewable energy device at an instant in time. This quantitative relationship and the reference profile are then used to predict the energy output of the renewable energy device at a future instant in time. The electric immersion heater 8 can therefore be controlled in an efficient manner to exploit the predicted energy provided by the renewable energy device.

Title: Vibrator with concave cross-section
Inventor: ROBERTS ANDREW JOHN
IPC: A61H19/00
Filed: 2008-07-16
Abstract: A vibrator for stimulating the genitals has a head 10 of generally concave cross-section. The vibrator has a handle and a motor and produces vibrations of sufficient amplitude (preferably 2-3mm) that it can used through a person's clothing rather than in direct skin contact. The vibrator head may have a sliding connector 12 allowing the head to be attached or removed easily. The vibrations may be produced by an offset cam rotated by an induction motor and connected to a vibration plate. Damping means may limit the vibration amplitude whilst a surge protector and overheating cut-out protect the motor. The vibration frequency may be controlled by a dial and the device operated by an on-off switch of the momentary type.

Filed: 2008-06-17
Abstract: In a downloadable conditional access system (DCAS), preferably all DCAS-specific code is implemented in a configurable secure (CS) processor that is in communication with the host processor. Preferably, no DCAS-specific code is executed in the host processor. The host processor delivers commands to the CS processor, which the CS processor performs to configure itself in accordance with the particular DCAS encryption scheme used by the DCAS. Once configured, the CS processor executes a DCAS software module that has been downloaded to the CS processor, which looks for the corresponding EMMs and ECMs, processes them to obtain the CW, and then uses the CW to decrypt the content stream.

Abstract: 473,284. Projectile fuzes. SCHENK, E. H., and INDUSTRIAL COMMODITIES DEVELOPMENT CORPORATION. April 6, 1936, No. 10146. Convention date, Aug. 27, 1935. [Class 9 (i)] A clockwork time fuze according to the invention comprises a rotary timing member 60 in one piece with the casing 21 of the clockwork and rotating therewith within the setting cap 4, and a release bolt 54 movable forward longitudinally and parallel to the axis of the fuze under the action of a spring 56 to release the striker when at the appointed time a notch 59 in the timing member comes opposite a lug 58 on the bolt. The forward movement of the release bolt allows a ball 51 to escape into a recess 55 in the bolt to release the striker 47. The friction between the setting cap 4 and the body 1 of the fuze is adjusted by three setscrews 40, only one shown, bearing on a friction ring 41. The clockwork casing 21 is keyed to the setting cap until the moment of discharge by means of balls 42. On discharge, the clockwork sets back and the balls escape into lateral holes 43. At the same time, a lead washer 61 formed with a tooth 62 normally blocking the notch 59 is empaled on spikes 63 on the body of the fuze. When acceleration is over, the lead washer remains behind while the clockwork is returned forward by the striker spring 46. The clockwork casing then rotates between ball bearings, one in front, not shown, and one 44 behind. The striker 47 fires a detonator 64 and the explosion is transmitted by a " booster " charge 65 to the main charge of the projectile.

Abstract: 953,055. Semi-conductor devices. Y. WATANABE, and J. NISHIZAWA. March 23, 1960 [March 25, 1959], No. 10361/60. Heading H1K. A device with an inductance of at least a millihenry comprises a number of semi-conductor regions. One of these has a higher resistivity than the rest and is disposed between a second region for injecting carriers into it and a third region with a hooked potential distribution characteristic to which the injector carriers flow. The current flow time lag due to the length of the first region and other parameters of the device produces the required inductance. In a typical diode device of NPIP type (Fig. 1) the hooked potential occurs in the P zone 5. In alternative arrangements the P region 7 is replaced by a P region or point contact on the side of zone 6, and an ohmic contact made to the end of the intrinsic zone. In any of these arrangements an N-type region may be provided between P region 7 and its contact 3 in which case ohmic contacts may also be provided on the two P regions. A further arrangement, Fig. 7, consists of an intrinsic region with NP zone configurations at both ends and on one side. In this case all the N zones are provided with contacts. Two of the P zones may also be provided with contacts.
