Title: PAPR minimisation in OFDM by allocating the same information to two groups of sub-carriers and transposing the information in one of the groups
Inventor: PARKER STEVE CARL JAMIESON
IPC: H04B1/713
Filed: 2006-01-26
Abstract: This invention relates to a method of minimising Peak-to-Average-Power Ratio (PAPR) in OFDM transmission. The sub-carriers are divided into a first group (e.g. X2 to X63 of Fig. 5 on the fight hand side of the DC baseband carrier) and a second group (e.g. X67 to X128 on the left hand side of the DC baseband carrier). Symbols for transmission are mapped to the first group of caters, and the same symbols are copied and then transposed before being mapped to the second group of carriers. Transposition is by means of a transposition algorithm such as equations 8 and 9. In one embodiment the transposition associated with each one of the even numbered carriers of the second group is based on symbol information from both an even subcarrier and an odd sub-carrier of the first group, and may incorporate a mutual polarity function. Preferably transposition involves rendering a symbol into its negative form (i.e. reversing the sign of real and imaginary components). The invention is particularly suited to multiband-OFDM, especially in the case of conjugate symmetric mapping or dual cater modulation.

Filed: 2006-05-04
Abstract: A collapsible scaffold has a platform 11, folding legs 12 and a guardrail 13, wherein the angle of the legs to the platform when in use is variable. The guardrail preferably comprises two side frames 14 pivotally mounted on the platform and foldable about a second axis parallel to the first pivot axis. The first pivot axes of the two side frames may be at slightly different heights to allow compact folding. Each side frame may also carry an end gate 15 pivoted by a collar 29 on one end thereof and latchable onto the other side frame. Preferably each end gate is stowed flat against an upper part of the side frame. The deck platform 11 may have vertically extending corner posts 18 from which the guardrails pivot. Each corner post preferably houses a pin which comprises the first pivot axis and a recess for a second pin which may hold the gate vertical, the gate being vertically slidable to release the second pin. Vertical gate bars are preferably curved to accommodate the horizontal bars of the side frame when collapsed. The folding legs 12 are preferably pivotally mounted on the corner posts and are preferably telescopically extensible, being pinned at a desired length. The pin may comprise a spring-loaded internal pin or alternatively an external spring clip held pin. A support stay 34 may be provided to hold each leg at a predetermined angle. The stay preferably has a number of slots to provide different leg angles. The legs, preferably mounted in pairs by a horizontal bar which acts as ladder rung, may be pivotally mounted on the platform for folding flat. The guardrail may be demountably supported in sockets on the upper end of the corner posts. The folded scaffold is preferably adapted for compact stacking.

Title: Improved core of cylinder lock
Inventor: LIU TIEN-KAO
IPC: E05B27/00
Filed: 2008-06-13
Abstract: A cylinder lock comprises a core saddle assembly (10), a core (20), plural pin tumbler retaining stackers 3 of a linked upper pin tumbler bore 12 and lower pin tumbler bore 21, which contains a cap 31, a retaining spring 32, upper tumbler beads (50), a stacking globule 341-5 and a lower tumbler bead 35, and plural holding dimples on the peripheral surface at one parallel side of the lower pin tumbler bores. The core can be operated by multiple keys. Upon the first key being inserted into the core, the pin tumbler retaining stackers are pushed upwards to let the top surface of each stacking globule flush with the outer core surface so that the core and each lower tumbler bead together with each stacking globule become simultaneously rotated into un-locked state. Upon the second key being inserted into the core, the pin tumbler retaining stackers are pushed upwards to let the bottom surface of first stacking globule flush with the outer core surface so that the core and each lower tumbler bead together with rest stacking globules become simultaneously rotated into un-locked state. The first stacking globule drops in the corresponding holding dimples to disable operation of the first key. This applies to other keys by analogy. A reset piece may be provided to recover stacking globule into pin tumbler retaining stacker so that previous disabled keys are reset to operable condition. Not only convenience in only replacing the key is available, but also the burglarproof capability of the lock can be enhanced.
